2021年6月9日，欧盟食品安全局就食品酶凝乳酶和胃蛋白酶（chymosin and pepsin）的安全性评价发布意见。
据了解，这种食品酶来自牛犊和奶牛的皱胃，旨在用于奶酪生产的牛奶加工中。
经过评估，专家小组认为，在预期的使用条件下，不能排除通过饮食接触引起的过敏性致敏和诱发反应的风险，但这种情况发生的可能性很低。根据所提供的数据，小组得出结论，该食品酶在预期的使用条件下不会引起安全问题。部分原文报道如下：
The food enzyme containing chymosin (EC 3.4.23.4) and pepsin (EC 3.4.23.1) is produced from the abomasum of Bos taurus purchased from different rennet manufacturers by Laboratorios Arroyo S.A. The food enzyme is intended to be used in milk processing for cheese production. As no concerns arise from the source of the food enzyme, from its manufacture, and based on the history of safe use and consumption, the Panel considered that toxicological data were not required, and no exposure assessment was necessary. On the basis of literature data, the Panel considered that, under the intended conditions of use, the risk of allergic sensitisation and elicitation reactions by dietary exposure could not be excluded, but the likelihood for this to occur was considered to be low. based on the data provided, the Panel concluded that this food enzyme does not give rise to safety concerns under the intended conditions of use.
