METHOD OF PREPARING LIPID PRODUCT WHEN DEODORIZING OR PHYSICALLY REFINING VEGETABLE OILS AND FATS Russian patent published in 1998 - IPC

FIELD: butter and fats industry. SUBSTANCE: claimed method comprises distilling off free fatty acids, flavor- aromatic and odorizing agents at temperature not lower than 225 C in vacuum at certain values of consumption of live steam and condensation temperature and also at ratio of vapor volatile mixture and refined deodorized butter of 0.1:1 to 15:1. Distillation is carried out so that the desired product contains not more than 300 mg % tocopherols, not more than 20 mcmole/g of carbonyl compounds, not more than 0.8% $$$ peroxide compounds and has melting temperature of not higher than 45 C. The claimed method makes it possible to obtain vitaminized lipid product having high biological and physiological value due to enriching it in tocopherols and sterols and also due to high content of indispensable linoleic acid. This lipid product is useful as feed additive in nutrition ration of fur-bearing animals, fish, poultry, and in livestock breeding. EFFECT: more efficient preparation method.
