NOVEL USE OF SUBSTITUTED CHROMAN-6-OLS WITH EXTENDED LIPOPHILIC SIDE CHAINS
-
Page/Page column 19; 20, (2019/10/23)
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 in PUFA-containing edible oils such as marine oil, microbial oil, fungal oil, algal oil and PUFA-containing plant oil for human consumption. The present invention is further directed towards these PUFA containing edible oils comprising such substituted chroman-6-ols with extended lipophilic side chains of formula (I). The present invention is further directed to a method of preserving the shelf life of PUFAs and/or their esters in an edible oil comprising the step of adding at least one compound of formula (I) to said edible oil, as well as to a method of limiting the amount of oxidation of PUFAs and/or their esters in an edible oil which is exposed to air, comprising adding at least one compound of formula (I) to said edible oil, preferably in an amount of said compound of formula (I) ranging from 10 to 500 ppm, preferably ranging from 30 to 300 ppm, more preferably ranging from 100 to 250 ppm, based on the total amount of the edible oil.

, p. 1961 - 1964 (2007/10/02)
The natural α-tocopherol was synthesized by enzyme-catalyzed enantioselective hydrolysis.The unnatural enantiomer as a by-product was also converted to natural α-tocopherol by racemization and repeated enzyme-catalyzed hydrolysis.
