2) fluid formed by the weight ratio of 2 ~ 3:4 ~ 7 with propane and dme is for extraction agent, carry out subcritical abstraction to pre-treatment Semen Vitis viniferae powder, Extracting temperature is 49 ~ 53 DEG C, and extraction pressure is 2.5 ~ 2.9MPa, extraction time is 30 ~ 60min, and the extract obtained is raisin seed oil; After raisin seed oil extraction completely, change into dehydrated alcohol is that extraction agent carries out subcritical abstraction, extraction temperature is 58 ~ 63 DEG C, extracting pressure is 3.4 ~ 3.7MPa, extraction time is 30 ~ 50min, extract is evaporated to 1/3 ~ 1/6 of original volume, and concentrated solution is after active carbon adsorption drying, and the sorrel meal obtained is procyanidin extract.
In technique scheme,
Described active carbon adsorption is that concentrated solution is crossed activated carbon column with the flow velocity of 0.5 ~ 1.0BV/h, with 70% ethanolic soln eluent, then by elutriant concentrate drying.
Preferably, added water and yeast are respectively 35% and 0.1% of Semen Vitis viniferae weight.
Preferably, when first time extracts, the weight ratio of propane and dme is 2.5:6, and Extracting temperature is 52.5 DEG C, and extraction pressure is 2.7MPa, and extraction time is 40min.
Compared with prior art, the present invention has the following advantages:
Extracting method provided by the invention combines various effective extracting method, effectively can improve the purity of yield and extract, thus obtains the product of very high quality.Wherein, obtained raisin seed oil residual oil content is lower than 1.5%; Obtained pycnogenols yield can up to 85%, and purity can up to 98%.
