IR heating is useful in inactivating bacteria, spores, yeast, and molds in both liquid and solid foods by considering the following parameters: An increase in the power of the infrared heating source produces more energy and thus total energy absorbed by microorganisms (M/Os) increases, leading to microbial inactivation. 4.6 out of 5 stars 37. Other options New from $59.47. Impacts of broadband and selected infrared wavelength treatments on inactivation of microbes on rough rice. Lipooxygenase, an enzyme responsible for deterioration in soybeans, was inactivated 95.5% within 60 s of IR treatment (Kouzeh and others 1982). From the earliest, Shuman and Staley (1950) discussed that orange juice has a minimum absorption at the range between 3 and 4 μm, whereas dried orange solids have a maximum absorption at the same region.

Shorter treatment time was enough to inactivate pathogens at higher temperatures and the estimated Z value was 23 °C. Planck’s law gives the spectral-energy distribution of radiation emitted by the black body, as a function of temperature and wavelength E (λ, T). Fish and Fishery Products: Quality Indices, Production of High-Quality, Semi-dried Dorumuk (. A 10‐min treatment with infrared heating resulted in more than 90% reduction in B. subtilis population (Daisuke and others 2001). Far Infrared Irradiation Enhances Nutraceutical Compounds and Antioxidant Properties in Angelica gigas Nakai Powder. Drying and dehydration Infrared heating provides an imperative place in drying technology and extensive research work has been conducted in this area. The amount of the IR radiation that is incident on any surface has a spectral dependence because energy coming out of an emitter is composed of different wavelengths and the fraction of the radiation in each band, dependent upon the temperature and emissivity of the emitter. The rate of water loss increased due to a higher heat transfer rate, but the total water loss was reduced because of a shorter heating time. Along with the sound theoretical background on IR heating, the review also encompasses application of IR heating in food processing operations such as drying, dehydration, blanching, thawing, pasteurization, sterilization, and other miscellaneous food applications such as roasting, frying, broiling, and cooking, as well as in‐depth assessment of pathogen inactivation. Applications of IR heating in food processing operations The application of infrared radiation to food processing has gained momentum due to its inherent advantages over the con-ventional heating systems. A Short Update on Heat Transfer Modelling for Computational Food Processing in Conventional and Innovative Processing. curing of coatings, forming of plastics, annealing, plastic welding, and print drying. It depicts the principal absorption bands of the major food components compared to the absorption spectrum of water, indicating that the absorption spectra of food components overlap with one another in the spectral regions considered. IR heating is also gaining popularity because of its higher thermal efficiency and fast heating rate/response time in comparison to conventional heating. Workshop Agricultural Engineering and Agro‐Products Processing Toward Mechanization and Modernization in Agriculture and Rural areas, Water in biological systems (Seitaikei no mizu), An overview of new infrared radiation processes for various agricultural products, Thermal degradation kinetics of nutrients in orange juice heated by electromagnetic and conventional methods, Comparative study of heating processes for full‐fat soybeans. As the food is subjected to infrared radiation, it is absorbed, reflected, or scattered (a blackbody does not reflect or scatter). Infrared technology is used in many food manufacturing processes, such as drying, boiling, heating, peeling, polyphenol recovery, freeze-drying, antioxidant recovery, microbiological inhibition, sterilization grains, bread, roasting of food, manufacture of juices, and cooking food. Physical properties of infrared (IR) assisted hot air dried nutmeg (Myristica fragrans) seeds. For instance, at NIR wavelength region (λ < 1.25 μm), approximately 50% of the radiation is reflected back, while less than 10% radiation is reflected back at the FIR wavelength region (Skjoldebrand 2001). Such a controlled radiation can stimulate the maximum optical response of the target object when the emission band of infrared and the peak absorbance band of the target object are identical. What Is Radiant Heating. of Agricultural and Biological Engineering, Purdue Univ., West Lafayette, IN 47907, U.S.A. Impingement of infrared energy on the food surface may induce changes in the electronic, vibrational, and rotational states of atoms and molecules. The Wien Law explains the shift of the peak to shorter wavelengths as the temperature increases. Using concrete numbers, it highlights emphatically that Welltherm’s efficient infrared heaters can hold their own in a direct cost comparison with established heating systems like oil and gas, but also with heat pumps or pellet heating systems. Hebbar and others (2004) developed a continuous combined infrared and convective dryer for vegetables. Due to a lack of information, data on absorption of infrared radiation by the principal food constituents can be regarded as approximate values. Certain studies have been found in the literature applied to electronics (Bischorf 1990; Sakuyama and others 1995). Furthermore, infrared heating leading to a higher dehydration ratio implies that infrared heating reduces serious product shrinkage (Lin and others 2007). John is very interested in learning how infrared radiant heating works and what benefits the technology has over forced air units. However, the studies did not elaborate on the details or its implementation. of Hawaii, Honolulu, HI 96822, U.S.A. It is quite likely that the utilization of IR heating in the food processing sector will augment in the near future, especially in the area of drying and minimal processing. The solution procedure uses a fully implicit time‐stepping scheme to simulate the drying of potato during infrared heating in 3‐dimensional Cartesian coordinates. Water and organic compounds such as proteins and starches, which are the main components of food, absorb FIR energy at wavelengths greater than 2.5 μm (Sakai and Hanzawa 1994). However, research need for upcoming years may include the following: Selective heating: There is not much literature on selective heating using IR radiation in foods. Potential application of infrared assisted freeze drying (IRAFD) for banana snacks: Drying kinetics, energy consumption, and texture. Pungency of onions following infrared radiation decreased with reduction in moisture (Gabel and others 2006). In conventional heating, which is achieved by combustion of fuels or by an electric resistive heater, heat is generated outside of the object to be heated and is conveyed to the material by convection of hot air or by thermal conduction. There seems to be a lack of consistent methods to explore the intrinsic selective heating process in the area of food engineering. The system had the capability to selectively heat higher absorbing components to a greater extent using optical band pass filters that can emit radiation in the spectral ranges as needed. The effect of short and medium infrared radiation on some drying and quality characteristics of quince slices under vacuum condition. The chemical composition and resistance of the M/Os in various growth phases are different. Head rice yield was improved by infrared heating and the whiteness of the rice was maintained (Meeso and others 2004). Infrared heating can be applied to various food processing operations, namely, drying, baking, roasting, blanching, pasteurization, and sterilization. Course material. European Journal of Lipid Science and Technology. Therefore, it is obvious that inactivation efficiency is associated with the radiation spectrum (Hamanaka and others 2006). Some are briefly discussed are, The use of IR radiation technology for dehydrating foods has shown several advantages such as a reduction in drying time, alternate energy source, increased energy efficiency, the uniform temperature in the product while drying, better-quality finished products, a reduced necessity for airflow across the product, a high degree of process control parameters, and space-saving along with the clean working environment. Masamura and others (1988) confirmed increased drying rates of potatoes with increasing surface temperature of the radiator. For example, S. aureus population was reduced by approximately 2 and 5 log10 CFU/mL at 321 °K, when the sample depths were 2.9 and 0.9 mm, respectively. Infrared heating raised the internal temperature of the strawberries not above 50 °C, while the surface temperature was high enough to effectively inactivate microorganisms. It was also found that the pasteurization effect of FIR irradiation was much higher than conductive heating on exponential phase cells under the same conditions. Effects of infrared radiation combined with heating on grape seeds and oil quality. For materials with a rough surface, both regular and body reflection can be observed. Heat and Mass Transfer, Energy and Product Quality Aspects in Drying Processes Using Infrared Radiation. D values of B. subtilis at 120, 140, 160, and 180 °C were 26 min, 66, 9.3, and 3.2 s, respectively. Moreover, a single equation was derived to predict the moisture ratio change during infrared drying (0 to 240 min) of apple in the temperature range of 50 to 80 °C. Soy protein was heated about 6 °C higher than glucose after 5 min of heating, exhibiting a reverse phenomenon when heating without the filter. Amino acids, polypeptides, and proteins reveal 2 strong absorption bands localized at 3 to 4 and 6 to 9 μm. Journal of Thermal Analysis and Calorimetry. Then vegetative cells formed from spores will be activated and thus spores will be inactivated. Table 6 lists advantages and disadvantages of IR heating compared to other thermal processing techniques (Dostie and others 1989; Sakai and Hanzawa 1994; Mongpreneet and others 2002). Exponential phase cells are more sensitive to IR heating than stationary phase cells. Infrared (IR) radiation heating, a promising drying method, can penetrate the material and be converted into thermal energy by molecular vibration to heat the product. Based on the wavelength, it can be divided into three regions namely near- (0.78-1.4 μm), mid- (1.4-3.0 μm) and far-IR (3.0-1000 μm) among which far-IR radiation is considered as more advantageous for food processing, Since most food components absorb radiative energy in this region. Advanced Food Process & Production Engineering. Save my name, email, and website in this browser for the next time I comment. Drying Performance and Product Quality of Sliced Carrots by Infrared Blanching Followed by Different Drying Methods. A novel dryer design with carbonic heating film technology and drying of high moisture lignite coal. The total energy being emitted at all wavelengths (ET) by the black body at a specific temperature from an IR source. In general, numerical methods applied to solve the set of equations are finite elements, finite difference, and finite volume or the control volume method. The Two conventional types of infrared radiators used for process heating are: – Tubular/flat metallic heaters (long waves), – Quartz tube heaters (medium- and short wave). The effect of IR on food quality attributes is discussed in the context of samples and process parameters. It is often difficult to decide which solution strategy would give the best results and which would require the least computing time (Ranjan and others 2001). FREE Shipping. Infrared radiation transfers thermal energy in the form of electromagnetic waves. Water molecules inside M/Os readily absorb infrared radiation. Extending Shelf Life of Brown Rice Using Infrared Heating. Application of infrared radiation in a stepwise manner by slowly increasing the power, with short cooling between power levels, resulted in less color degradation than with intermittent infrared heating (Chua and Chou 2005). The populations in a suspension of bacterial spores subjected to lethal heat treatment were simulated using a composite model involving simultaneous, independent activation and inactivation of dormant but viable spores, and inactivation of activated spores. State and amount of water inside spores, bonding conditions of water molecules, and location of water molecule within M/Os affect their responses to infrared heating (Hamanaka and others 2006). With conductive heating, similar damages were observed; however, RNA, protein, and cell wall showed more vulnerability to IR heating than conductive heating. Recently, Tanaka and others (2007) combined Monte Carlo FIR radiation simulations with convection–diffusion air flow and heat transfer simulations to investigate the suitability of the method for surface decontamination in strawberries. Food must be packed, in cans, foil or paper and cardboard - food safe and leak proof. Tsai and Nixon (1986) investigated the transient temperature distribution in a multilayer composite, semitransparent or transparent, absorbing and emitting medium exposed to a thermal radiative heat flux. However, in the last few years significant research efforts have been made in the area of IR heating of foods. $155.84 $ 155. Designing thermal functional materials by coupling thermal transport calculations and machine learning. LWT – Food Science and Technology. Selective IR heating was found to differentially deliver a higher degree of lethality to individual fungal spores. Comparison of lipid degradation in raw and infrared stabilized rice bran and rice bran oil: matrix effect. However, this method is inappropriate when dried … Similarly, Das and others (2004) also reported that the Page model adequately fitted the experimental drying data while studying the drying characteristics of high‐moisture paddy. A hybrid non-invasive method for internal/external quality assessment of potatoes. Compared to regular freeze‐drying, IR‐assisted freeze‐drying of yam brought about lower color differences as well as faster dehydration. Quantitative Microbiology in Food Processing. An 8‐min infrared radiation at a wattage of 3.22 kW/m2 resulted in approximately 1.8, 1.9, 2.7, and 3.2 log10 reduction of E. coli, when NA, PCG, RFP, and CP enriched agars were used for enumeration, respectively. Moreover, IR emitters react very quickly and can therefore be well controlled - an important precondition for the quality of food. Application of FIR drying in the food industry is expected to represent a new process for the production of high‐quality dried foods at low cost (Sakai and Hanzawa 1994). To take account of this, the concept of grey bodies is used, and the Stefan-Boltzmann equation is modified to, The radiator is the main component of any IR equipment that comes in different types and shapes. It’s been nearly 40 years since the last book on infrared heating for food processing was published, and in the meantime, the field has seen significant progress in understanding the mechanism of the infrared (IR) heating of food products and interactions between IR radiation and food components. Water effect on absorption of incident radiation is predominant over all the wavelengths, suggesting that selective heating based on distinct absorptivities for a target food material can be more effective when predominant energy absorption of water is eliminated. Certain characteristics of IR heating such as efficiency, wavelength, and reflectivity set it apart from and make it more effective for some applications than others. 78:281-288. Hence, it is a challenge to cut off the entire spectral distribution to obtain a specific bandwidth. Stabilization of rice bran milling fractions using microwave heating and its effect on storage. The heat is similar in nature to that of sunlight, which is why it is also known as a synthetic means to provide warmth. Energy would thereafter be transported by heat conduction in the food. This reaction occurs below the ignition temperature of gas so that no flame is produced. Calculation of heat penetration during infra‐red frying of meat products, Infra‐red radiation for food processing I. However, in a proposal suggested for the solution of heat transfer problems for food materials, it was recommended that if the solution region represents a simple rectangular domain, then the traditional finite difference methods should be the preferred discretization strategy (Turner and Perre 1996). Exploring the IR convective drying of onion slices, Sharma and others (2005) observed that the drying time increased with the increase in air velocity at all infrared powers applied; however, it reduced with an increase in infrared power and the drying took place in the falling drying rate period. Heat transfer occurs through one of 3 methods, conduction, convection, and radiation. Detailed insight into the theoretical explanation of IR effects, especially with regard to its interaction with food components, changes in taste and flavor compounds and living organisms. Although infrared heat‐treated turkey samples were slightly darker than the controls after treatments, refrigerated storage for an hour resulted in no significant difference in color values as measured by L*, a*, and b* values (Huang 2004). Stefan-Boltzmann’s law gives the mathematical expression which tells that the black body emission radiance is proportional to the fourth power of the temperature. Effects of Pre-cooking Methods on Quality Characteristics of Reheated Role of Individual Heat Transfer Mechanisms Within a Model Baking Oven Heated by Porous Volumetric Ceramic Burners. Demand of infrared (IR) heating technology has been increasing in industrial heat treatment processes to replace traditional heating methods because of this technology’s high energy efficiency. Khan and Vandermey (1985) prepared ground beef patties by IR broiling in a conveyorized broiler. Number of times cited according to CrossRef: A Review on Applications of Infrared Heating for Food Processing in Comparison to Other Industries. However, this method is inappropriate when dried vegetables are used as ingredients of instant foods because of low rehydration rate of the vegetables. IR heating is attractive primarily for surface heating applications. Emerging Pet Food Drying and Storage Strategies to Maintain Safety. A similar study explored by Dagerskog (1979) used 2 alternative types of infrared radiators for frying equipment, which were quartz tube heaters (Philips 1kW, type 13195X) whose filament temperature was 2340 °C at 220 V rating, corresponding to λmax of 1.24 μm as NIR region, and tubular metallic electric heaters (Backer 500W, type 9N5.5) at a temperature of 680 °C at 220 V, corresponding to λmax of 3.0 μm as FIR region. A wide variety of infrared heating of food options are available to you, such as cb, ce. Infrared heating works differently from convection heating in that it provides warmth to a solid body rather than warming up the surrounding air. Zhongli Pan. Journal of Food Measurement and Characterization. Impingement of infrared energy on the food surface may induce changes in the electronic, vibrational, and rotational states of atoms and molecules. Critical Reviews in Food Science and Nutrition. IR‐heating was found to improve rehydration rate and degree of swelling of pinto beans; however, cooking time of pinto beans significantly increased. Electric infrared emitters also provide flexibility in producing the desired wavelength for a particular application. Types of food materials: As described earlier, IR radiation has a poor penetration capacity. Infrared drying of dill leaves: Drying characteristics, temperature distributions, performance analyses and colour changes. Development of a continuous drying apparatus equipped with FIR heaters, NIR heaters, and hot air blast can reduce the economic costs, drying time, and operating temperature. Furthermore, canola seeds had higher dehulling capacity after infrared heating (McCurdy 1992). Journal of the American Oil Chemists' Society. It was experimentally observed that as the thickness of the layer increases, a simultaneous decrease in transmittance and increase in reflection occurs. Along with microwave, radiofrequency (RF), and induction, IR radiation transfers thermal energy in the form of electromagnetic (EM) waves and encompasses that portion of the EM spectrum that borders on visible light and microwaves (Figure 1). Energy and mass balance developed by Ratti and Mujumdar (1995) accounts for the shrinkage of the heated particle and absorption of infrared energy. Drying time with infrared heating was reduced to 7 h, as opposed to 11 h with convectional drying. Hashimoto and others (1990, 1994) studied the penetration of FIR energy into sweetpotato and found that FIR radiation absorbed by the vegetable model was damped to 1% of the initial values at a depth of 0.26 to 0.36 mm below the surface, whereas NIR showed a similar reduction at a depth of 0.38 to 2.54 mm. Food and Feed Safety Systems and Analysis. This observation implies that approximately 0.1, 0.9, and 1.4 log reductions were caused by inhibitory actions of PCG, RFP, and CP, respectively. Application of combined electromagnetic radiation and conventional convective heating is considered to be more efficient over radiation or convective heating alone, as it gives a synergistic effect. This article reviews aspects of IR heating and presents a theoretical basis for IR heat processing of food materials and the interaction of IR radiation with food components. Performance of electrochemical micromachining of copper through infrared heated electrolyte. FIR energy penetration into the food has gained ceaseless concern. An initial increase in B. subtilis population was caused by heat shock germination of spores. Jun and Irudayaraj (2003) utilized selective infrared heating in the wavelength range of 5.88 to 6.66 μm using optical bandpass filters for inactivation of Aspergillus niger and Fusarium proliferatum in corn meal. The infrared frequency range is between 300 gigahertz and 400 terahertz and wavelength of 0.78 to 1000 µm and thus occupies the part of the electromagnetic spectrum with a frequency less than that of visible light and greater than that of most radio waves with some overlaps. Computations were validated against measurements with a thermographic camera. A Comprehensive Review on Infrared Heating Applications in Food Processing. Sterilization of wheat surface was investigated by Hamanaka and others (2000). … Absorption intensities at different wavelengths depending on the food components. Technicalities. Surface temperature of petri dish was 100 °C after a 2‐min exposure for all the heaters. Optimization of the FIR heating process for shrimp dehydration found that the effect of plate distance on the drying rate was not significant, whereas the drying rate increased monotonically with an increase in the plate and air temperature (Fu and Lien 1998). When radiant electromagnetic energy impinges upon a food surface, it may induce changes in the electronic, vibrational, and rotational states of atoms and molecules. Innovative Food Science & Emerging Technologies. 3D modeling of food products: Studies on IR heating have generally been applied to foods with a simple 1D or 2D geometry.

Maximum D values of B. subtilis spores inactivated by IR heat differed with initial water activities ranging from 0.6 to 0.9. Abe and Afzal (1997) investigated 4 mathematical drying models, namely, an exponential model, a Page model, a diffusion model based on spherical grain shape, and an approximation of the diffusion model to address the thin‐layer infrared drying characteristics of rough rice. Dielectric | Ohmic | Infrared Heating PRO Ch. It should be noted that Dagerskog and Österström (1979) first used a bandpass filter (Optical Coating Laboratory Inc., type nr L‐01436‐7) in their frying experiment of pork to transmit only the wavelength above 1.507 μm, which turned out be a good example for design of selective IR heating systems to emit the spectral regions of interest. Sakai and Hanzawa (1994) have discussed the effects of the radiant characteristics of heaters on the crust formation and color development at the surfaces of foods such as white bread and wheat flour. Gabel and others (2006) compared the drying and quality characteristics of sliced high‐solids onions dried with catalytic infrared (CIR) heating and forced air convection (FAC) heating. IR heat‐treated lentils were found to be darker than raw lentils, though there was no visible indication (Arntfield and others 2001). Effect of peak wavelength and bandwidth: As indicated earlier, food and microbial components absorb certain wavelengths of infrared radiation. Direct inquiries to author Jun (E‐mail: However, vegetable size should be restricted to no more than 5 mm in thickness to improve drying efficiency (Sakai and Hanzawa 1994). However, with the lower energy source (FIR), the increasing rate of core temperature was dependent on the fat content, showing that targeted core temperature was achieved more quickly as fat content increased. Effects of voltage gradient and fat content on changes of electrical conductivity of frozen minced beef meat during ohmic thawing.
