Camel milk casein hydrolysates by Alcalase, -Chymotrypsin and Papain were ultra-filtered and different
fractions were assessed for antioxidant and antimicrobial activity. The casein hydrolysate fractions were
analyzed for antioxidant activities viz. 2,2 -azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS),
2,2 -diphenyl-1-picrylhydrazyl (DPPH) and Ferric reducing antioxidant power assay (FRAP), and antimicrobial
activity by inhibition zone assay. In ABTS, DPPH and FRAP assay, the inhibition activity was
recorded significantly (P < 0.05) higher for whole hydrolysares whereas among fractions F2 (1–5 kDa),
F3 (5–10 kDa) of all the three hydrolysates had comperatively higher antioxidant activity. It was also
observed that - Chymotrypsin could produce protein hydrolysates and fractions with higher antioxidant
activities. The antimicrobial activity (zone of inhibition; mm) was also recorded higher for whole
hydrolysates as compared to their fractions; however, among different fractions the inhibition zones
were almost comparable. It was also observed that Alcalase and -Chymotrypsin could produce paptides
with higher antimicrobial activity. The results suggested that camel milk casein hydrolysates could be
fractioned to get specific molecular weight peptides, however, for food application or for direct human
consumption, use of whole hydrolysates could be more beneficial with regards to its functionalities and
cost of production.
