FIELD: food industry. ^ SUBSTANCE: method involves cleaning the vegetable raw material, extracting it with 0.1 hydrochloric acid solution, filtration, sorption by means of sorbent with clay content of 10% minimum. After sorption the sorbent with anthocyanins from the mother solution is centrifugally separated, the mother solution is removed and the following desorption is performed with a solvent which is 1% hydrochloric acid solution in ethanol centrifugally separating re-extract from the sorbent. ^ EFFECT: invention enables to simplify the method, improve the target product quality and increase storage stability. ^ 1 tbl, 2 ex |
