| Abstract: | Bone protein hydrolysates were prepared by limited alcalase hydrolysis (5 h). The hydrolysates were formulated (0-3%,w/w) into pork patties to determine the antioxidant efficacy. 0.02% BHA (butylated hydroxyanisole) was used as a positive control.Lipid oxidation in patties during storage was analyzed by measuring the TBARS and protein carbonyl content. The results showed that bone protein hydrolysates possessed significant antioxidant activity, and antioxidant activity increased with the increasing hydrolysates concentration. Sensory evaluation indicated that bone protein hydrolysates improved the color and decreased lipid oxidation flavor of pork patties. The 2% bone hydrolysates possessed the highest antioxidant activity and better sensory quality, and its effect was closed to 0.02% BHA. |
