Dielectric properties of mashed potatoes relevant to microwave and radio-frequency (RF) pasteurization and sterilization processes were measured over 1 to 1800 MHz and 20 °C to 120 °C. Effects of moisture content (81.6% to 87.8%, wb) and salt content (0.8% to 2.8%, wb) were investigated. Dielectric loss factors and constants decreased with frequency. Dielectric loss factors increased with tempe...

In an attempt to correlate freezable water with freezing injury, the thermal behavior of pea (Pisum sativum L.) and soybean (Glycine max L. Merr) seed parts at different moisture contents were compared with survival of the seeds when exposed to low temperatures. Thermal transitions between -150 and 10 degrees C were studied using differential scanning calorimetry. In pea, reduction of germinabi...

Seafood is an important food source for many. Consumers should be entitled to an informed choice, and there is growing concern about correct composition labeling of seafood. Due to its high price, it has been shown to be vulnerable to adulteration. In the present study, we focus on moisture levels in seafood. Moisture and crude protein contents of chilled and frozen cod, pangasius, salmon, shri...

Gelatinisation and retrogradation of starch in wheat flour systems and whole wheat grains were studied using differential scanning calorimetry (DSC) and the impact of these events on starch digestibility was investigated. Retrogradation of starch was studied with partially and fully cooked (boiled at 100°C for 12 min and 32 min, respectively) wheat grains that were subjected to storage at 22°C ...

Negative impacts on the environment, bird well-being, and farm worker health indicate the need for abatement strategies for poultry litter NH(3) generation. Type of bedding affects many parameters related to poultry production including NH(3) losses. In a randomized complete block design, 3 trials compared the cumulative NH(3) volatilization for laboratory-prepared litter (4 bedding types mixed...

Distribution of lipid classes and groups and fatty acid composition of neutral and polar lipid fractions corresponding to two edible sites (head and tail) were investigated. Proximate composition and essential and toxic mineral contents wer...

Seed priming is a physiological seed enhancement method. Hydroor osmotic priming can advance germination under adequate moisture conditions. During direct seeding on well-drained paddy and upland fields, rice seeds occasionally encounter low soil moisture conditions. Under these conditions, rice seeds need to undergo rapid germination and secure emergence through improved water absorption capac...

Background and Objectives: Desiccation is a necessary procedure to eliminate moisture from foodstuffs in industries, especially pharmaceutical, food and tobacco industries. In the present study, a mathematical modeling was assessed for vacuum drying of the licorice roots. Materials and Methods: Fresh licorice roots were dried at 50 mbar. Temperatures included 22to 150°C and diameters of roots ...

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...
