| titleOfInvention | A kind of preparation method of food-grade theaflavins substance |
| abstract | The present invention relates to a kind of preparation methods of food-grade theaflavins substance, specially fresh tea leaves are added in buffer containing ethyl alcohol and are homogenized, catechins are added after filtering into filtrate and lead to aerobe fermentation, it is eluted by macroporous resin adsorption on fermentation liquid and with the above-mentioned buffer of 0.3~1.0BV, start collection efflux to elution in adsorption process when occurring catechins in efflux to finish, obtain collection liquid, fresh tea leaves are added in collection liquid again and are homogenized, through filtering, fermentation, absorption, collection liquid is obtained again, aforesaid operations can be repeated several times, after macroporous resin adsorption on last time fermentation liquid, pure water is used respectively, percent by volume is the elution of 20~30% and 60~80% ethanol waters, collect 60~80% ethanol eluates, concentration, it is dry, theaflavins substance is made.This method simple process, strong operability is low in cost, is easy to industrialize, and there is no the security risks such as organic solvent is exceeded for product. |
