Indicators of ice cream quality with the NF-concentrate of curd whey

The influence of whey concentrate obtained by nano-filtration on organoleptic characteristics, thermal and dimensional stability of creamy ice-cream is studied. According to experimental data the curves of melting are built, their mathematical processing is carried out and the resulting equation to calculate the average speed of the ice cream with different concentration of whey protein concentrate melting is obtained. Generalized results of the taste analysis are presented graphically in the form of profile diagrams.

Milk protein composition and its technological properties at Saanen goat’s breed depending on their genotype by beta-lactoglobulin level

The research has been carried out in Vysokogorsk district of the Tatarstan Republic where the protein composition of milk from 80 Saanen goat’s breed by electrophoresis in polyacrylamide gel have been studied. It has been found that goat’s and cow’s milk has the similar protein composition. Interspecies differences are more strongly observed in the concentration of individual fractions. It has been found the studied animals in locus β-Lg have two genetic variants: among AA and BB the prevailing one is genotype AA.
