(a)Vitamin D is added to food as the following food ingredients:
(1)Crystalline vitamin D2 (C28H44O, CAS Reg. No. 50-14-6), also known as ergocalciferol, is the chemical 9,10-seco(5Z,7E,22E)-5,7,10(19),22-ergostatetraen-3-ol. The ingredient is produced by ultraviolet irradiation of ergosterol isolated from yeast and related fungi and is purified by crystallization.
(2)Crystalline vitamin D3 (C27H44O, CAS Reg. No. 67-97-0), also known as cholecalciferol, is the chemical 9,10-seco(5Z,7E,)-5,7,10(19)-cholestatrien-3-ol. Vitamin D3 occurs in, and is isolated from, fish liver oils. It is also manufactured by ultraviolet irradiation of 7-dehydrocholesterol produced from cholesterol. It is purified by crystallization. Vitamin D3 is the vitamin D form that is produced endogenously in humans through sunlight activation of 7-dehydrocholesterol in the skin.
(3)Vitamin D2 resin and vitamin D3 resin are the concentrated forms of irradiated ergosterol
(D2)and irradiated 7-dehydrocholesterol
(D3)that are separated from the reacting materials in paragraphs (a)(1) and
(2)of this section. The resulting products are sold as food sources of vitamin D without further purification.
(b)Vitamin D2 and vitamin D3 as crystals meet the specifications of the Food Chemicals Codex, 3d Ed. (1981), pp. 344 and 345, which is incorporated by reference.
