摘要： 为了研究蜂王浆酶解产物在不同湿度环境下的吸湿保湿性能，利用碱性蛋白酶对蜂王浆进行酶解，以蜂王浆冻干粉和骨胶原为对照，对蜂王浆酶解产物在25 ℃，相对湿度分别为20%、50%和65%条件下酶解产物的吸湿和保湿性能进行测定。结果表明：在本实验湿度环境范围内，在底物质量分数为8%、酶与底物含量比1%、酶解温度45 ℃、酶解时间3 h、pH值9.5的酶解条件下，酶解产物的吸湿和保湿性能均高于蜂王浆冻干粉，且明显优于骨胶原。说明蜂王浆通过碱性蛋白酶酶解的产物具有良好的保湿和吸湿性能，在吸湿保湿化妆品开发方面具有广阔的开发前景。
Abstract: In order to research the moisture adsorption and retention capacity of enzymatic hydrolysates from royal jelly under different  humidity conditions, the royal jelly proteins were  hydrolyzed  by alkali protease, and the moisture adsorption and retention capacity of their hydrolysates were determined under the conditions of 25 ℃, relative humidities of 20%, 50% and 65%, respectively, in comparison with lyophilized royal jelly powder and bone collagen. The results showed that the enzymatic hydrolysates exhibited better performance both in moisture adsorption and retention test than lyophilized royal jelly powder and bone collagen did. The optimum conditions were as follows: substrate concentration of 8%, enzymatic concentration of 1%, temperature of 45 ℃, enzymatic hydrolysis time of 3 h and pH 9.5. It is safe to draw the conclusion that enzymatic hydrolysis will be an efficient method for obtaining ingredients from royal jelly with good moisture adsorption and retention capacity and it has a bright future in exploitation of moisturekeeping or moistureadsorbing cosmetic.
