The additive 'Zinc chelate of methionine sulfate' is zinc chelated with methionine in a molar ratio 1:1, with a minimum zinc content of 19.1%. Owing to the limitations of the tolerance study, it could not be used for the assessment of safety for target animals; therefore, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP Panel) cannot conclude on the safety of zinc chelate of methionine sulfate for the target species. No concerns for consumer safety are expected from the use of the zinc chelate of methionine sulfate in animal nutrition when used up to the maximum EU authorised zinc levels in feed. Zinc chelate of methionine sulfate should be considered as a skin and eye irritant, and as a skin sensitiser; it is considered to pose a risk by inhalation to the users. The additive under assessment, zinc chelate of methionine sulfate, is intended to be a substitute for other authorised zinc additives and will not further increase the environmental burden of zinc; therefore, the FEEDAP Panel considers that the use of the additive in animal nutrition would not pose an additional risk for the environment. Based on literature studies and a specific study conducted with the additive under assessment, zinc chelate of methionine sulfate is an available source of zinc for all animal species.
添加剂“蛋氨酸锌螯合物”是锌与蛋氨酸以1:1摩尔比螯合而成,锌含量最低为19.1%。由于耐受性研究存在局限性,无法用于评估对目标动物的安全性;因此,欧洲食品安全局动物饲料添加剂和产品或物质专家小组(饲料添加剂和产品或物质专家小组)无法就蛋氨酸锌螯合物对目标物种的安全性得出结论。在动物营养中使用蛋氨酸锌螯合物时,若使用量不超过欧盟饲料中锌的最大授权水平,则预计不会对消费者安全造成担忧。蛋氨酸锌螯合物应被视为皮肤和眼睛刺激物以及皮肤致敏剂;认为其对使用者有吸入风险。所评估的添加剂蛋氨酸锌螯合物旨在替代其他已获授权的锌添加剂,且不会进一步增加锌的环境负担;因此,饲料添加剂和产品或物质专家小组认为在动物营养中使用该添加剂不会对环境造成额外风险。基于文献研究以及对所评估添加剂进行的一项特定研究,蛋氨酸锌螯合物是所有动物物种可用的锌来源。
