摘要：The aim of the research was to evaluate the effect of the encapsulation process on collagen hydrolysate. Commercial collagen hydrolysate (CH) was spray-dried with maltodextrin (MD) with two different dextrose equivalents (MD12: 10-12 dextrose equivalent (DE) maltodextrin and MD 19: 19-20 DE maltodextrin) and two different core-wall material ratios of 10:90 and 20:80 in pilot scale spray dryer. Four different groups of encapsulated collagen hydrolysate were created such as MD1210 (10% collagen peptide + 90% MD12), MD1220 (20% collagen peptide + 80% MD12), MD1910 (10% collagen peptide + 90% MD19), and MD1920 (20% collagen peptide + 80% MD19). Moisture, water activity, hygroscopicity, solubility and antioxidant activity of collagen peptides significantly (p˂0.01) decreased with encapsulation (p=0.01). The DPPH (1,1- diphenyl-2-picrylhydrazyl) radical scavenging activity analysis results showed that the collagen hydrolysates antioxidant activity was dependent on the dose and the antioxidant activity was significantly decreased by the encapsulation process.
