摘  要:
为了进一步提升南瓜的经济价值,通过对南瓜中环丙基甘氨酸和环丙基丙氨酸两种非蛋白质氨基酸提取工艺中温度、提取时间、料液比、磺基水杨酸浓度等影响因素的试验分析,确定南瓜中环丙基甘氨酸和环丙基丙氨酸的最佳提取条件:提取温度为80℃,磺基水杨酸浓度为1%,提取时间为3h,料液比为1:30,并采用氨基酸分析仪对南瓜中这两种氨基酸含量进行了测定;确定南瓜中环丙基甘氨酸和环丙基丙氨酸含量分别为96.48mg·100g-1和162.60mg·100g-1。

摘  要:
To promote commercial value of pumpkin power,the effects of the temperature,extraction duration,sulfosalicylic acid concentration and the solute to solvent ratio on the Cyclopropylgly-cine and Cyclopropylalanine extraction efficiency from pumpkin power was studied.The optimal conditions were determined.The result showed that the optimal condition was 80 ℃,3.0 h,sulfosalicylic acid concentration 1%,and the solute to solvent ratio was 1:30,which determined that cyclopropylglycine and cyclopropylalanine contents of pumpkins were respectively 96.48 mg·100 g-1 and 162.60 mg·100 g-1 by using L-8800 amino acid analyzer.
