The concentration of orotic acid in dry whey ranged between 64 and 146 mg/100 g and appeared dependent on whey type. The orotic acid of modified whey products, prepared commercially by electrodialysis, ultrafiltration, gel filtration, or polyphosphate precipitation was between 7 and 124 mg/100 g, which was less than that of dry whey. It appears that whey processing methods do not concentrate or...

The aim of this study was identifying a suitable food grade enzymes to hydrolyze whey protein concentrates (WPCs), to give the highest bioactivity. WPCs from ultrafiltration retentate were adjusted to 35% protein (WPC-35) and hydrolyzed by enzymes, alcalase, α-chymotrypsin, pepsin, protease M, protease S, and trypsin at different hydrolysis times (0, 0.5, 1, 2, 3, 4, and 5 h). These 36 types of...

This pre-feasibility study evaluates the use of residual leafy green biomass from broccoli (Brassica oleracea, var. Italica) and kale Sabellica) as feedstock for protein fractionation potential application fractions in food feed products. The concentration, recovery content phenols dietary fibre these sources were investigated. Field produce side-stream analysis showed that among side-streams p...
