objective: whey protein is a byproduct of dairy industry, where cheese and casein are manufactured.this is the major protein content which is loss during the formation of yogurt and cheese. methods: if this is added to the diet then that can enhance the nutritioal value for the diet, which will be very usefull. results: in this study we try to find it out that the whey protein has the antibioti...

Growth parameters and biochemical composition of the green microalga Chlorella vulgaris cultivated under different mixotrophic conditions were determined and compared to those obtained from a photoautotrophic control culture. Mixotrophic microalgae showed higher specific growth rate, final biomass concentration and productivities of lipids, starch and proteins than microalgae cultivated under p...

The construction of Saccharomyces cerevisiae strains that ferment lactose has biotechnological interest, particularly for cheese whey fermentation. A flocculent lactose-consuming S. cerevisiae recombinant expressing the LAC12 (lactose permease) and LAC4 (beta-galactosidase) genes of Kluyveromyces lactis was constructed previously but showed poor efficiency in lactose fermentation. This strain w...

The present work was aimed to define and validate farmstead production of lactose-free Pecorino di Osilo cheese, fresh ricotta cheese, and salted and smoked ricotta cheese (Ricotta mustia). The enzymatic activity of the commercial preparation containing lactase (1.1 g/mL), preliminarily tested using a spectrophotometric titration, showed activity equal to 4950±40 neutral lactase unit/g. The amo...

Chitosan, a cationic carbohydrate polymer manufactured from chitin in shrimp and crab wastes, coagulated suspended solids in cheese whey as effectively or more so than ten commercial synthetic polymers. Concentrations of suspended solids after settling were reduced over 90% by coagulation at pH 6.0 with a ratio of chitosan to suspended solids of 2.15% (1:46.5). The yield of coagulated solids wa...

Whey is a green-yellowish fluid that derives from cheese-making and casein manufacture. The compositional quality and properties of whey can differ greatly, which depends on production technology and milk quality used. The main constituents of whey’s dry matter are lactose (46-52 g/L) and whey proteins (6-10 g/L) (Jelen, 2003; Adam et al., 2004; Jeličić et al., 2008). Whey fermentation is initi...

Whey, a by-product of cheese manufacturing is rich in nutrients such as lactose, proteins, and mineral salts. The fungus Mortierella isabellina was used for production of oil containing γ-linoleic acid (GLA) during fermentation on deproteinized whey permeate (DP-WP) with and without lactase addition. The maximum oil concentration was 3.65 g/L in DP-whey (16.0% lactose) without enzyme treatment....

Whey is a by product in the process of cheese production. Composition and characteristics of whey are depending on the production technology of the end product and on the quality of the used milk. Liquid whey consists approximately 93% of water and contains almost 50% of total solids present in the milk of which lactose is the main constituent. Lactose is the main constituent of whey while prot...
