Impact of protein standardization of milk powder with lactose or pemeate on whey protein nitrogen index and heat classification
Whey protein nitrogen index (WPNI) is a well-known method of classifying nonfat dry milk powder (NFDM) based on its heat treatment. This classification scheme provides one criterion for the selection of NFDM for food applications. However, the effects of variation in NFDM composition on WPNI are not well documented. The objective of this study was to determine the effects of changing protein co...

Energy concentration and phosphorus digestibility in whey powder, whey permeate, and low-ash whey permeate fed to weanling pigs.
Two experiments were conducted to determine DE and ME, the apparent total tract digestibility (ATTD) of P, and the standardized total tract digestibility (STTD) of P in whey powder (3,646 kcal/kg), whey permeate (3,426 kcal/kg), and low-ash whey permeate (3,657 kcal/kg) fed to weanling pigs. The DE and ME in the 3 whey products were determined using 32 barrows (9.2 ± 0.4 kg of BW). A basal diet...
متن کاملFermentation of lactose to ethanol in cheese whey permeate and concentrated permeate by engineered Escherichia coli
BACKGROUND Whey permeate is a lactose-rich effluent remaining after protein extraction from milk-resulting cheese whey, an abundant dairy waste. The lactose to ethanol fermentation can complete whey valorization chain by decreasing dairy waste polluting potential, due to its nutritional load, and producing a biofuel from renewable source at the same time. Wild type and engineered microorganisms...
متن کاملEffect of pH on Structural Properties of Heat-Induced Whey Protein Gels
Formation and structure of whey protein heat-induced gels (100 mg mL-1) through heat treatment at 80 °C and pH modifications at three pH values of acidic (2), isoelectric (5.6) and neutral (7) were studied. The obtained results indicated that the nature of the primary gel networks was different at each pH value. The heat-induced gels produced at pH of 2 and 7, had acceptab...
