The food enzyme phosphoinositide phospholipase C (1-phosphatidyl-1D-myo-inositol-4,5-bisphosphate inositoltrisphosphohydrolase, EC 3.1.4.11) is produced with the genetically modified strain NZYM-DI by Novozymes A/S. The genetic modifications did not give rise to safety concerns. The production strain has been shown to qualify for the qualified presumption of safety (QPS) status. The food enzyme was co nsidered free from viable cells of the production organism and its DNA. It is intended to be used for degumming of fats and oils. Since residual amounts of total organic solids are removed during washing and purification steps applied during degumming, dietary exposure was not estimated. As the production strain B. NZYM-DI qualifies for the QPS approach to safety assessment and no issue of concern arose from the production process, no toxicological data were required. A search for similarity of the amino acid sequence of the food enzyme to known allergens was made and no match was found. 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 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.
食品酶磷酸肌醇磷脂酶C(1-磷脂酰-1D-肌醇-4,5-二磷酸肌醇三磷酸水解酶,EC 3.1.4.11)由诺维信公司(Novozymes A/S)使用转基因菌株NZYM-DI生产。基因改造未引发安全问题。生产菌株已被证明符合安全合格假定(QPS)状态。该食品酶被认为不含生产生物体的活细胞及其DNA。它旨在用于油脂脱胶。由于在脱胶过程中应用的洗涤和纯化步骤会去除总有机固体的残留量,因此未估算膳食暴露量。由于生产菌株B. NZYM-DI符合QPS安全评估方法,且生产过程未出现任何问题,因此无需毒理学数据。对该食品酶的氨基酸序列与已知过敏原进行了相似性搜索,未发现匹配项。专家小组认为,在预期使用条件下,不能排除膳食暴露引发过敏致敏和激发反应的风险,但认为发生这种情况的可能性较低。根据提供的数据,专家小组得出结论,在预期使用条件下,这种食品酶不会引发安全问题。
