标准范围
This International Standard specifies a method for the simultaneous quantitative determination ofvitamin E (α-tocopherol and α-tocopheryl acetate) and vitamin A (13-cis and all-trans isomers of retinylpalmitate and retinyl acetate) present in all forms of infant and adult formulas (powders, ready-to-feedliquids and liquid concentrates).Retinol is not used for fortification purposes and therefore is not addressed in this method. The innateamount in products is insignificant.Stereoisomers of vitamin E, α-tocopherol and α-tocopheryl acetate, are not differentiated in this method.
