Understanding mechanisms that are involved in heating foods in a microwave field is necessary to develop novel foods for microwave applications. You’ve supercharged your research process with ACS and Mendeley! Engineered biochar derived from food waste digestate for activation of peroxymonosulfate to remove organic pollutants.

The results of this study provide indicators for treatment process assessment and measures to increase value-added products from food waste. The specific heat capacities were determined for RFW and DFW, while their morphological properties at different temperatures were equally considered using scanning electron microscopy and Fourier transform infrared spectroscopy. latent heat of fusion to form ice, or latent heat of vaporisation to change water to vapour) where the temperature remains constant while the phase change takes place. A schematic DSC thermogram showing an endothermal, first-order phase transition, for example, melting. The required pressure and temperature of process steam are controlled by the rate of heating in the boiler (see also section 10.2). The importance of thermal conductivity is shown in sample problem 10.1 and sample problem 11.1 (Chapter 11). Heat exchangers are commonly used for the purposes of heating and cooling foods. Thermal diffusivity is a measure of a material’s ability to conduct heat relative to its ability to store heat. M.J. Lewis, in Physical Properties of Foods and Food Processing Systems, 1996. Composition data for foods are readily available in the literature. The retort processing method is one of the most mature processing technologies. Equations for predicting the thermal properties of these food components have been developed as functions of temperature in the range of − 40 to 150 °C. Theoretically, it is possible to apply a mathematical modeling method combined with modern computation techniques for the simulation of thermal processing of solid or particulate liquid foods, provided all the processing conditions can be discovered and all the thermo-physical properties of the food obtained by independent experiments. Suraj Adebayo Opatokun, Lina F. Yousef, Vladimir Strezov. The definition of specific heat can be formulated as follows: The specific heat of a material can be determined experimentally by static (adiabatic) calorimetry or differential scanning calorimetry or calculated from measurements involving other thermal properties. Naturally, the latter would only be used where there is a hermetically sealed skin packaging. As shown in Figure 3.10 thermograms showing first-order transitions can be analyzed to obtain transition temperatures. Properties of saturated steam, Adapted from Singh and Heldman (2001b) original data from Keenan, J.H., Keyes, F.G., Hill, P.G. Fan Lü, Zhang Hua, Liming Shao, Pinjing He. Specific heat cp (kJ.kg−1.K−1) is among the most fundamentals of thermal properties. A phase transition causes a temperature difference between the sample and the reference, which is recorded. It is a ratio involving thermal conductivity, density and specific heat, and is found using Equation 10.6: where α (m2s− 1) = thermal diffusivity and ρ (kg m− 3) = density. Valorization of digestates from urban or centralized biogas plants: a critical review. Equation 10.3 is used to estimate specific heat and takes account of the mass fraction of the solids contained in the food: where M = moisture content (wet-weight basis, expressed as a fraction not percentage). DTA and DSC are closely related methods, which are probably the most common techniques in the determination of phase transitions in inorganic, organic, polymeric, and also food materials. DSC may also measure the amount of energy supplied to the sample and the reference. Refrigerated meats are generally classified as chilled or frozen. The amount of electrical energy used by the consumer is measured in terms of kilowatt hours or units. These represent cheaper energy sources than mechanical refrigeration or expendable refrigerants, which are required for achieving the statutory temperatures, which lie below 10°C. Sampriti Kataki, Samarendra Hazarika, D.C. Baruah. Effect of pre-treatment on sequential anaerobic co-digestion of chicken litter with agricultural and food wastes under semi-solid conditions and comparison with wet anaerobic digestion. When a current flows through a potential difference, a quantity of energy is dissipated in the form of heat. Immediately after heat treatment or cooking, it will be necessary to commence cooling under controlled conditions. The key thermal properties include specific heat, thermal conductivity, and thermal diffusivity.

Electricity costs can be reduced by trying to spread the load throughout the day, thereby ensuring that there are no excessive peaks in electrical demand. A formula to predict thermal conductivity based on the composition of foods is shown in Equation 10.5: where kW (W m− 1 °C− 1) = thermal conductivity of water, Xw = mass fraction of water, ks = (W m− 1 °C− 1) = thermal conductivity of solids (assumed to be 0.259 W m− 1 °C− 1). Table 10.3. CAB Direct provides where X = mass fraction and subscripts w = water, p = protein, f = fat, c = carbohydrate and a = ash. Pyrolysis coupled anaerobic digestion process for food waste and recalcitrant residues: Fundamentals, challenges, and considerations. Instruments used for measuring potential difference are known as voltmeters. A reduction in moisture content causes a substantial reduction in thermal conductivity.
