Vitamin A Palmitate, chemical name as retinol acetate, is the earliest vitamin being discovered. There are two types of Vitamin A: one is retinol which is the initial form of VA, it only exists in animals; another one is carotene. Retinol can be composited by β-carotene coming from plants. Inside the body, under the catalysis of β-carotene-15 and 15′-double oxygenase, β-carotene is transformed into ratinal which is returned to retinol by the performance of ratinal reductase. Thus β-carotene is also called as vitamin precursor. Vitamin A Palmitate Powder is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, among which beta-carotene is the most important.
Compared with retinol, retinyl palmitate resists oxidation and activity loss, tolerates high temperature and long-term storage, ideal for powders, softgels and premixes.
Soluble in vegetable oils, insoluble in water; two mainstream forms: oil and microcapsule powder.
