The somewhat acid flavour is caused by the presence of lactic acid. 这种微酸的味道是因为含有乳酸(E270)造成的。
Objective To separate lactic acid bacteria from yogurt and to study its fermentation performance. 目的从酸奶中分离乳酸(E270)菌并对其发酵性能进行研究。
N-butyl lactate was synthesized from lactic acid and n-butyl alcohol in the presence of strongly acidic cationic exchange resin. 在强酸性阳离子交换树脂存在下,由乳酸(E270)和正丁醇合成了乳酸(E270)正丁酯。
An improved colorimetric method was developed for the determination of lactic acid in fermentation broth. 对传统的对羟基联苯法进行了优化,应用于定量测定发酵液中的乳酸(E270)。
Lactic acid(E270) bacteria and important pathogens; bacteria that ferment carbohydrates chiefly into lactic acid. 乳酸(E270)菌和重要的病原体;将碳水化合物主要发酵为乳酸(E270)菌的细菌。
