南瓜叶浓缩蛋白制品的食用安全性初步评价

Preliminary dietary safety evaluation on protein concentrates from pumpkins(Cucurbita moschata) leaves

采用我国《食品安全性毒理学评价程序》中所规定的标准方法和实验模型,对南瓜叶浓缩蛋白制品的食用安全性进行评价。结果显示,该产品小鼠经口LD50值大于21.501g/kg·bw,属无毒级;小鼠30d喂养未显示任何毒副作用。因此,该产品对实验动物不具有急性毒性作用。

The dietary safety of pumpkin leaf protein products was evaluated in this experiment by using standard methods and experimental models described in the procedures for toxicological assessment on food safety. The result suggested that the LDso of pumpkin leaf protein concentrate would be higher than 21.501g/kg.bw, which indicated the non-acute toxicity of the experimental material according to the procedures for toxicological assessment on food safety. And,no abnormality was observed after feeding the experimental animals for 30d. Therefore,it was concluded that the pumpkin leaf protein concentrate experimente.d should not be acutely toxic to the experimental animals.
