ABSTRACT:
New stabilizers for carotene, which retard its oxidation and protect it against destruction, and which are 3,5-di-carbonyl derivatives of 2,6-dimethyl-1,4-dihydropyridine, conforming to the general formula ##SPC1##
Where R is a lower alkyl, such as methyl, or an alkoxy, such as an ethoxy group.
The introducing of said stabilizers into fodder products for animals such as, for instance, into grass four, makes it possible to preserve valuable nutritive properties of such products during a long period of time, of at least 6 months.
