The present invention is directed towards the use of substituted chroman-6-ols with extended lipophilic side chains of formula (I) wherein one of the two substituents R1 and R2 is C12-21-alkyl and the other of the two substituents R1 and R2 is either hydrogen or C1-5-alkyl or (CH2)n—OH with n being an integer from 1 to 5, and wherein A is CH(R3), and wherein R3, R4 and R6 are independently from each other H or C1-4-alkyl, and wherein R5 is H or OH or C1-4-alkyl or C1-4-alkoxy; with the proviso that at least two of R4, R5 and R6 are not methyl, when R3 is H and one of the substituents R1 and R2 is methyl and the other of the two substituents R1 and R2 is C12-21-alkyl, as antioxidants, especially in feed such as pet food and feed ingredients such as fish meal, insect meal and poultry meal, as well as PUFA-containing oil such as marine oil, microbial oil, fungal oil, algal oil and PUFA-containing plant oil. The present invention is further directed towards feed ingredients and feed for insects, aquatic and terrestrial animals comprising such substituted chroman-6-ols with extended lipophilic side chains of formula (I).
本发明的目的是使用具有式(I)扩展亲脂侧链的取代色满-6-醇,其中两个取代基 R1 和 R2 中的一个是 C12-21 烷基,两个取代基 R1 和 R2 中的另一个是氢或 C1-5 烷基或 (CH2)n-OH (n 为 1 至 5 的整数),A 是 CH(R3),R3、R4 和 R6 相互独立地是 H 或 C1-4 烷基,R5 是 H 或 OH 或 C1-4 烷基或 C1-4 烷氧基;但 R4、R5 和 R6 中至少有两个不是甲基,当 R3 是 H,取代基 R1 和 R2 中的一个是甲基,两个取代基 R1 和 R2 中的另一个是 C12-21-烷基时,作为抗氧化剂,特别是在饲料中,如宠物食品和饲料配料,如鱼粉、昆虫粉和家禽粉,以及含 PUFA 的油,如海洋油、微生物油、真菌油、藻类油和含 PUFA 的植物油。本发明还涉及用于昆虫、水生和陆生动物的饲料原料和饲料,这些饲料原料和饲料包含具有式(I)扩展亲脂侧链的此类取代的色烷-6-醇。
