The thicking of secondary cell wall may be one of the reason of ethanol accumulation. The activities peak value of CAT, PPO and POD were advanced and the activity of AAO gradually increased, the content of total phenol decreased sharply, the production rate of superoxide anion ,the content of MDA and H2O2 in flesh of 'brumal jujube' increased treated with ABA during storage, this showed ABA accelerated the scenescence of fruit, the effects of ABA on 'brumal jujube'fruit was contrary to GA.

点红冬枣贮藏过程中，各有机酸(柠檬酸、t-顺乌头酸、琥珀酸、延胡索酸)含量逐渐下降，苹果酸略有增加，丙酮酸含量逐渐增加，峰值出现后下降，说明丙酮酸的增加与进入三羧酸循环的有机酸流量的降低是导致果实乙醇发酵的机制之一；点红冬枣中蔗糖含量较高，贮藏期间，蔗糖含量下降，葡萄糖和果糖含量增加，气调贮藏可延缓果实蔗糖降解和葡萄糖和果糖含量的增加。

Kefir manufactured by goat milk powder had significantly higher medium chain fatty acid than by fresh goat milk. This could be explained by the higher fat content in goat milk powder. Addition of growth promoters decreased the level of medium chain fatty acids. By comparing both growth promoters, adding peptide had significantly lower caproic acid and caprylic acid than isomaltooligosaccharide did.

羊乳克弗尔中链脂肪酸之研究结果显示，羊乳粉制作的羊乳克弗尔的羊油酸、羊脂酸及葵酸含量均比鲜羊乳的含量高：克弗尔的中链肪酸随著添加物之不同而有所改变，整体来说，以不添加任何生长促进物的对照组其C6、C8和C10脂肪酸含量为高，添加肽类组最低。

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

试验表明在以松香、重烷磺酸钠、石油磺酸钠为主要乳化剂时，要获得优良的乳化液，需满足以下几个条件：(1)需在乳化油配方中加入适量的乳化剂，且其中阴离子乳化剂总量与非离子乳化剂总量的应保持适当的比例；(2)乳化油中环烷酸锌的量与其它乳化剂总量要保持正比关系；(3)乳化油中松香的量不易过大，且油酸的加入量应与松香量成正比；(4)乳化油中水分含量不易过高(一般不能大于8％)，过高时稳定性不好，易分层。

A-Methylnaphthalene contains a methyl group, which is a strong donor group, so the reaction of a-methylnaphthalene with C14 AOS acid had a higher conversion of aromatic than did the reaction of benzene with C14 AOS acid. After alkylaryl sulfonic acid is formed, it will continue to react with another AOS acid to rapidly produce dialkylaryl disulfonic acids owing to the electron- donating effect of the long alkyl chain in the alkylaryl sulfonic acid molecule.
