| titleOfInvention | A kind of preparation method of non agricultural chemical residuum black rice anthocyanin |
| abstract | Disclosed by the invention is the process that extraction purification prepares non agricultural chemical residuum anthocyanidin from black rice, and this method comprises the following steps：（1）Black rice extracts：Black rice raw material is taken, first adds raw material weight 5% 9%, the aqueous citric acid solution that mass fraction is 50 60%, it is 1 to be supplemented pure water to solid-liquid ratio:2‑1:3, after extracting 8 10 hours, coarse filtration, centrifugation, centrifugate using aperture as 0.5 micron of ceramic membrane filter, obtain filtrate again respectively；（2）Purifying：Purified using macroporous absorbent resin, eluted using the ethanol water that mass fraction is 40 60%；（3）Extraction：Extract and separate is carried out using the petroleum ether of 12 times of volumes, removes part residues of pesticides；（4）Silica gel column chromatography：Residues of pesticides are further removed through silica gel column chromatography；（5）Dry：Spray-dried that powdered black rice anthocyanin product is made, its anthocyanidin content is more than 30%, and residues of pesticides do not detect；Present invention process is simple, non agricultural chemical residuum, and anthocyanidin content is high, can fully meet the market demand, ensures food security. |
