[0021] 2. The preparation process of proanthocyanidins (extraction is rose particle feeding-ultrasonic continuous countercurrent extraction-primary filtration-membrane fine filtration (ultrafiltration / nanofiltration)-membrane concentration (reverse osmosis membrane concentration)-vacuum freeze-drying-powder collection-packaging ). The specific process includes:

[0022] extraction:

[0023] Take raw material A and put it into ultrasonic continuous countercurrent low-temperature extraction equipment for extraction, add purified water (conductivity lower than 0.1) with a mass ratio of raw materials of 1:1-10 times, extraction temperature 5-40°C, ultrasonic power 15-100 Hz (Hz) , continuous countercurrent extraction for 1-10 hours to obtain extract B and rose petal residue.

[0024] Preliminary filtration: Prefilter the extract B, and use a 100-300 mesh filter for preliminary filtration, and then filter through a ceramic membrane treatment equipment to obtain filtrate C, and st...

[0031] Pretreatment: Take fresh roses - remove the calyx and keep the petals - dry with a low-temperature heat pump (this is the only way to do this, other methods may have no fragrance and deteriorate the quality of anthocyanins) - crush to a size of 60 mesh - get double roses raw material A;

[0032] Extraction: Take raw material A and put it into ultrasonic continuous countercurrent low-temperature extraction equipment for extraction, add purified water (conductivity lower than 0.1) with a mass ratio of raw materials of 1:4 times, extraction temperature 20 ° C, ultrasonic power 50 Hz (Hz), countercurrent extraction 3 hours, to obtain extract B and rose petal slag.

[0033] Preliminary filtration: The extract B is prefiltered, and the 200-mesh filter is used for preliminary filtration, and then the filtrate C is obtained by ceramic membrane filtration with ceramic membrane processing equipment, and stored at 5°C.

Abstract

The invention relates to a method for extracting natural procyanidine from rosa rugosa plena. The method includes the steps that fresh roses are pretreated, and a rosa-rugosa-plena raw material A is obtained; the raw material A is put into an ultrasonic continuous countercurrent low-temperature extracting device and extracted, purified water is added, continuous countercurrent extracting is carried out, and extracting liquid B is obtained; the extracting liquid B is primarily filtered to be subjected to ceramic membrane filtering through a ceramic membrane treating device, and filter liquid Cis obtained, and is preserved at the temperature of 5 DEG C to 20 DEG C; the filter liquid C is subjected to ultrafiltration or nanofiltration, impurity molecules with the molecular weight larger than500 Dalton-100,000 Dalton are cut off, and membrane refined filter liquid D is obtained; the membrane refined filter liquid D is subjected to membrane concentration dehydration processing through a reverse osmosis membrane concentration device, and concentrated liquid E with the solid content of 5% to 20% is obtained; the concentrated liquid E is frozen, concentrated solid F is obtained, the concentrated solid F is vacuumed, frozen and dried, and a natural procyanidine product is obtained. The rose procyanidine produced with the method is deep in color, easy to preserve and low in productioncost and can be applied to the food field or the cosmetic field.
