VEGETABLE OIL REFINEMENT METHOD Russian patent published in 2014 - IPC C11B3/00 

FIELD: food industry.

SUBSTANCE: invention relates to fat-and-oil industry. The vegetable oil refinement method envisages mixing of unrefined vegetable oil with a water solution of a hydrating agent represented by a culinary salt solution having concentration equal to 11- 16% in an amount of 0.5-0.8% of the oil weight; after mixing one performs the produced mixture stirring during 16-20 minutes, treatment with an acidic reagent solution having concentration equal to 21-25% in an amount of 0.35-0.80% of the oil weight and stirring during 16-25 minutes; into the produced mixture one adds a water solution of an alkali reagent represented by a liquid sodium glass solution or a solution of SilicaGel RAF 200 reagent for refinement of vegetable oils in an amount of 50% of the required estimated quantity; one proceeds with further continuous stirring for silicic acid gel formation and then determines acid number of oil; for neutralisation of free fatty acids one adds a solution of liquid sodium glass solution or a solution of SilicaGel RAF 200 reagent for refinement of vegetable oils in an amount of 50% the required estimated quantity. After neutralisation and soapstock flakes formation, one adds 5-6% solution of FL 45 C polycationite in an amount of 60-70 g per 1 ton of vegetable oil into the produced mixture and stirs the mixture during 16-25 minutes; then oil is settled, filtered and frozen out; treatment with reagents is performed at a temperature of 25-30°C.

EFFECT: invention allows to create a high-tech refinement method allowing to increase performance of production of refined oil with improved organoleptic properties, reduce the prime cost of the product manufacture as well as enhance the product organoleptic indices due to the mixture homogeneity.
