牛奶中助眠功能成分研究进展

Advances in Research on Functional Components of Sleep Aid in Milk

失眠不仅给人们带来了精神和生理困扰,还带来了巨大的经济损失。牛奶是一种潜在的促睡眠食品。通过调整牧场光照条件和奶牛日粮配方,可以增加奶牛体内褪黑素合成,牛奶中天然褪黑素含量增加。牛奶中α-乳白蛋白富含色氨酸等活性物质,能够对睡眠起到促进作用。此外,向牛奶中加入γ-氨基丁酸、酪蛋白水解肽、缬草提取物等具有助睡眠功效的活性成分,也能起到一定的促睡眠作用。

Insomnia not only brings mental and physical problems,but also causes huge economic losses.Milk is a potential sleep-aid food.By adjusting the light conditions of the house and the formula of the cow diet,the melatonin synthesis in the cows could be increased,and the natural melatonin content in the milk is increased.Alpha-lactalbumin in milk is rich in active components such as tryptophan,which can promote sleep.In addition,the addition of active ingredients such as gamma aminobutyric acid,casein hydrolyzed peptide,and valerian extract to the milk can also play a positive role in promoting sleep.
