The article studied on processing technology of tomato beverage using tomato as material, they did experiment aim to increase juice yield , stability of the beverge and to keep colour. The results indicated juice yield is able to reach 81.5% after preheating, adding pectase , pressure filtering, the processing technology improved the utilization of tomato.

以番茄为原料进行饮料的加工，针对提高番茄出汁率、饮料稳定性、饮料色泽的保持工艺研究实验，结果发现，对番茄预热后，再加果胶酶处理、加压过滤工艺可使番茄的出汁率达到81.5%，提高了番茄的利用率；番茄饮料中添加2‰，质量比5：2：3的羧甲基纤维素钠、黄原胶、琼脂复配增稠剂可使饮料在常温保存三个月仍具有良好的稳定性。

ABSTRACT Immobilized penicillin acylase (from E.coli) was used to catalyze 7 phenylacetamido 3 E propenyl cephalosporanic acid hydrolyzation into 7 amino 3 E propenyl cephalosporanic acid. Then, trans APRA was acylated with hydroxyethyl ester of 4 hydroxy D phenylglycine to obtain trans cefprozil.

以7 苯乙酰氨基 3 E 丙烯基 3 头孢菌素 4 羧酸为原料，在青霉素酰化酶作用下，首先酶法水解得到3 E 丙烯基 3 头孢菌素 4 羧酸，过滤固相酶，滤液调pH分离得到反式APRA固体；在青霉素酰化酶作用下，反式APRA再与对羟基苯甘氨酸乙二醇酯缩合，得到反式头孢丙烯；酶法合成所得的产品与进口反式头孢丙烯对照品一致。
