Abstract
(EN)
A process for purifying vitamin A consisting of heating a vitamin A preparation in an inert atmosphere, at a temperature below 170 °C and a pressure of less than 4 mm of mercury, said heating taking place in a vessel shielded from light is disclosed. The vitamin A obtained from this process is mixed with from 0.5:1 to 2:1 parts of tocopherol to vitamin A. The vitamin A and tocopherol mixture can be encapsulated in acacia gum, starch, pectins or other suitable materials. When the vitamin A is encapsulated, the level of tocopherol required is less, preferably from 0.05:1 to about 1:1 parts of tocopherol to vitamin A is used in an encapsulated vitamin A composition. Other antioxidants can be added.

Procédé de purification de la vitamine A consistant à porter une préparation de vitamine A en atmosphère inerte à une température inférieure à 170 °C et sous une pression de moins de 4 mm de mercure, cette chauffe s'effectuant dans un récipient isolé de la lumière. La vitamine A obtenue selon ce procédé est mélangée avec du tocophérol sous un rapport de 0,5 à 2 parties pour une de vitamine A. Ce mélange de tocophérol et de vitamine peut être enrobé dans de la gomme arabique, de l'amidon, des pectines ou toute autre matière appropriée. Lorsque la vitamine A est enrobée, le niveau de tocophérol nécessaire est moins élevé: on utilise de préférence de 0,05 à 1 partie de tocophérol pour une partie de vitamine A pour une composition de vitamine A enrobée. On peut ajouter d'autres antioxydants.
