Abstract: The present invention is directed towards the use of 2H-chromens and their derivatives of formula (I) and/or of formula (II) wherein R1 and R2 are independently from each other H or C1-11-alkyl or (CH2)n—OH with n being an integer from 1 to 6 or R1 and R2 together represent a keto group, and wherein R3, R4, R5, and R6 are independently from each other H or C1-6-alkyl or C1-6-alkoxy, and R7 is H or C1-6-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 2H- chromens and their derivatives of formula (I) and/or of formula (II).

Abstract: The present invention is directed towards the use of at least one compound of formula (I) wherein R1, R2 and R3 are independently from each other H or linear C1-6-alkyl or branched C3-8-alkyl, as antioxidant, especially in feed such as pet food and feed ingredients such as fish meal, insect meal and poultry meal, as well as PUFA-containing oils 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 twin chromanols of formula (I).

Abstract: The present invention is directed towards the use of substituted chroman-6-ols of formula (I) wherein R1 and R2 are independently from each other H or C1-11-alkyl or (CH2)n—OH with n being an integer from 1 to 4, or R1 and R2 represent together a keto group, 10 A is CHR3 or C(═O), 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, 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 of formula (I).

Abstract: 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).
