摘要
采用水提法提取燕窝唾液酸,并运用Box-Behnken设计(BBD)确定唾液酸的最优水提工艺;在果蝇培养基中添加燕窝水解物,研究其对果蝇寿命的影响.结果表明,燕窝唾液酸的最优水提工艺条件为:液料比20∶1、水提温度103℃、水提时间23 min,按此工艺条件得到的唾液酸提取率为(9.08±0.12)%.燕窝水解物可延长雌雄性果蝇的半数死亡时间,在果蝇培养基中添加1.2 g·L-1燕窝水解物均可延长雌雄性果蝇的寿命,寿命延长率分别达20.4%和16.8%,表明燕窝在延长果蝇存活时间方面有一定的作用.
The aqueous extraction process of birds nest sialie acid and the effect of sialie acid on drosophila life were verified. The results showed that the experimental sialic acid yield of （9.08 ± 0.12） % was achieved under the conditions of solid-liquid ratio 20 ： 1, temperature 103 ℃, time 23 mln, and pH 7. Compared to the control group, each test group of drosophila had longer mean time to death. Medium dose groups extended the life of the female and male drosophila to 20.4% and 16.8% respectively. It suggests that bird nest sialic acid has the function of anti-aging.
