| 摘要 |
FIELD: biotechnology, in particular production of bioactive product. ^ SUBSTANCE: invention relates to production of bioactive product by purification of mineral-origin natural raw material. Claimed method includes stone oil breaking up to particle size not more than 0.1 mm, extraction thereof with water at 15-25°C and simultaneous addition of citric acid. Further obtained extract is filtered, boiled down under vacuum and at temperature of 60-70°C up to dry matter content of 88-90 mass %. ^ EFFECT: increased effectiveness of raw material treatment due to enhanced ratio of target product in extraction process. ^ 2 tbl, 2 ex |
