2025年4月24日，歐盟食品安全局（EFSA）發布消息，歐盟食品安全局（EFSA）發布關于無水甜菜堿（betaine anhydrous）和鹽酸甜菜堿（betaine hydrochloride）作為所有動物飼料添加劑的授權更新申請的評估。
經過評估，專家小組得出結論，該添加劑在授權使用條件下對目標物種、消費者和環境都是安全的。在授權更新的情況下，無需評估添加劑的功效。部分原文報道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of betaine anhydrous and betaine hydrochloride for the renewal of its authorisation. The applicant provided evidence that the additives betaine anhydrous (solid form) and betaine hydrochloride (solid form) both produced by chemical synthesis currently on the market comply with the existing conditions of authorisation. The use of betaine anhydrous and betaine hydrochloride as feed additives in animal nutrition remains safe for target species, consumers and the environment under the current authorised conditions. Regarding user safety, betaine anhydrous and betaine hydrochloride are irritant to skin and eyes. Betaine hydrochloride is also a dermal and respiratory sensitiser. Any exposure to these additives is considered a risk. These conclusions apply, in principle, to any preparations containing the active substances. There is no need for assessing the efficacy of the additives in the context of this renewal of the authorisation.
