Effect of microwave heating on vitamins A, E, B₁, B₂and B₆in milk

Milk Flash Pasteurization by the Microwave and Study its Chemical, Microbiological and Thermo Physical Characteristics

“…Microwave pasteurization gives less damaged product comparison with traditional thermal treatment, this is due to the short treatment time and thermal radiation [4,5]. Sieber et al [5], Lau et al [6], Wang et al [7], and Albert et al [8], founds that the loss of free amino acids was less than the traditional way.…”

“…Sieber et al [5], Lau et al [6], Wang et al [7], and Albert et al [8], founds that the loss of free amino acids was less than the traditional way. Sieber et al [5] stated that pasteurized milk by microwave has not harmful effects on health.…”

“…Sieber et al [5], Lau et al [6], Wang et al [7], and Albert et al [8], founds that the loss of free amino acids was less than the traditional way. Sieber et al [5] stated that pasteurized milk by microwave has not harmful effects on health. John et al used a microwave for pasteurization of milk in HTST at 72°C for 15 seconds as a quick method, also they found a reduction in total bacteria, psychotropic bacteria counts, E. coli and alkaline phosphates in comparison with pasteurized milk in fast way.…”

Physical and Chemical Charateristics of Milk. Variation due to Microwave Radiation

“…So, Demel et al (1990) found no loss of vitamin A, β-carotene and vitamin B1 or B2 in microwave-treated pasteurized milk and a loss of approximately 17 % for vitamin E and 36 % for vitamin C. Vitamin A was reduced slightly in milk (1.5 or 3.5 % milk fat) heated to 80 to 90 °C on a hotplate or microwaved for 4, 5 min, regardless of the heat source. 27 According to Sieber et al (1993) vitamin B1 was not diminished in the upper and lower parts of microwave-treated milk and in stirred or unstirred milk. In both cases, the content of vitamin C was reduced.…”

“…Furthermore, the retinol present in milk could suffer from the influence of the microwaves used for defrosting. 20 These results suggest that it is important to protect milk stored in glass flasks from light, including through preventative measures such as simply wrapping the flasks in aluminum foil. Another prophylactic measure could be vitamin A supplementation to guarantee infants their necessary supply, avoiding increased risks of morbidity and mortality.…”
