【Abstract】 Objective: To determine the moisture absorption and retention capacity of enzymatic hydrolysates from royal jelly under different conditions. Methods: In comparison with royal jelly and bone collagen, the moisture absorption and retention capacity of enzymatic hydrolysates from royal jelly were determined under conditions of 20 ℃, 81% and 43% relative humidities. Results: The enzymatic hydrolysates showed better performance both in moisture absorption and retention test than royal jelly and bone collagen did. The optimum conditions were as follows: substrate concentration 7.5%; enzyme concentration 1.25%; temperature 50 ℃; time of hydrolysis 4 h and pH 8. Conclusion: Enzymatic hydrolysis can raise the moisture absorption and retention capacity of royal jelly. Moreover, both sides might be improved by modifying the process conditions of enzymatic hydrolysis. So enzymatic hydrolysis would be an efficient method for obtaining ingredients from royal jelly with good moisture absorption and retention capacity, resolvability and low relative molecular weight.更多还原
