Sodium caseinate (88.03% protein based on dry weight) was hydrolyzed by Alcalase 2.4L and Protamex to 5%, 10%, 15% and 20% degree of hydrolysis (DH) respectively. Sodium caseinate and its hydrolysates were analyzed, compared and used for measuring some functional properties.
Protein solubility increased with increasing DH and all hydrolysates were from 84.8%~98% soluble between pH4.0~5.0 at 10%~20% DH. This result indicated solubility improvement of sodium caseinate at its isoelectric pH.
Through Two level design,three main effects:sodium caseinate(SC),vegetable oil and Span60 were selected from several factors that influence the Whipping Ability of non dairy cream.
The fractionation of sodium caseinate peptide by ultrafiltration separation was studied. Sodium caseinate peptide products (hydrolysis degree of 11.5%) can be separated into five components (>10 ku, 10~5 ku, 5~3 ku, 3~1 ku,<1 ku) in terms of molecular weight. The molecular weight distribution of each retentate was determined by SDS-PAGE.

Tween-stabilized emulsions oxidized faster as pH increased from 3 to 7, whereas a different behavior was observed in emulsions stabilized with sodium caseinate or a mixture of both emulsifiers.
Combined injections of sodium caseinate and phenobollne, the stimulant of protein synthesis, resulted in the development of more intensive morphological and functional manifestations of amyloidosis in old rats.
Investigation of behavioral phenomena showed that after injections of sodium caseinate the ability to memorize becomes suppressed, and manifestations of the depressive state are intensified.
Together with the structural impairments, injections of sodium caseinate evoke considerable shifts of the parameters of background mass electrical activity in the basolateral amygdala, dorsal hippocampus, and parietal cortex.
In this paper,a microencapsulated palm oil was made by spray drying with malt dextrin and sodium caseinate as wall material,glyceryl monostearate and sucrose esters of fatty acids as emulsifier.A optimum formula was got.The resulting microencapsulation has good solublility,flowability and emulsibility.
Through Two level design,three main effects:sodium caseinate(SC),vegetable oil and Span60 were selected from several factors that influence the Whipping Ability of non dairy cream.Then Box Behnken design and response surface analysis were used to determine the optimum level of the main effects.It is demonstrated that at SC 2.05%,vegetable oil 25.1%,Span60 0.43%,the overrun of non dairy cream can reach maximum,that is 332%.
The fractionation of sodium caseinate peptide by ultrafiltration separation was studied. Sodium caseinate peptide products (hydrolysis degree of 11.5%) can be separated into five components (>10 ku, 10~5 ku, 5~3 ku, 3~1 ku,<1 ku) in terms of molecular weight. The molecular weight distribution of each retentate was determined by SDS-PAGE. The result showed that fractional ultrafiltration separation can effectively separate sodium caseinate peptides.
