According to the technological method, a squeezing-type low-temperature low-pressure technology is employed for full separation of lycium ruthenicum murr pulp, and the concentrated juice has no impurity and less precipitation; and also the technological method mainly employs physical methods, less chemical reagents are used and no antiseptic is included.

Description

Extract the processing method of anthocyanidin from black matrimony vine

technical field:

The present invention relates to a kind of extracting method of anthocyanidin, particularly a kind of processing method of extracting anthocyanidin from black matrimony vine.

background technology:

Anthocyanidin is a kind of water colo(u)r, claims again cyanidin(e), is that nature one class extensively is present in the water-soluble natural pigment in plant, belongs to flavonoids.Be also the main present-color material in plant petals, the multicoloured color major parts such as fruit, vegetables, flowers are relevant with it.Anthocyanidin is present in the vacuole of vegetable cell, can be transformed by chlorophyll, can change color along with the soda acid of enchylema.It is partially red that enchylema is acidity, and it is partially blue that enchylema is alkalescence.Anthocyanidin (anthocyanins) is one of main pigment formed petal and fruit color.Anthocyanidin is plant secondary metabolism product, plays the part of important role on physiology.The color of petal and fruit can attract animal to pollinate and seed dispersal (Stintzing and Carle, 2004).Be common in the tissue of flower, fruit and epidermic cell and the following table cortex of cauline leaf.

Anthocyanidin is the antidotal nutritious supplementary of pure natural, studies have shown that it is that mankind nowadays is found good antioxidant, and its antioxidant property exceeds 50 times than vitamin-E, than vitamins C, exceeds 20 times.It is 100% to the biological effectiveness of human body, after taking, within 20 minutes, just can in blood, detect.It not only can prevent generating ahead of time of wrinkle of skin, also can maintain that normal cell links, blood vessel stable, strengthen the fine vascular circulation, improve flowing of capillary blood vessel and vein, and then reach the rapid healing of abnormal skin.Anthocyanidin is natural sunlight overcover, can prevent ultraviolet ray infringement skin, and skin belongs to reticular tissue, and wherein contained collagen protein and rigid albumen play an important role to the total of skin.

Anthocyanidin, in Europe, is called as " oral skin cosmetics " especially vaccinium oxycoccus pigment, and skin nutrition strengthens skin immunization power, tackles various allergic conditions.The discovery of black matrimony vine, having overturned original blueberry is the fruit containing the king of anthocyanidin, the black contained anthocyanidin of matrimony vine is several times even tens times more than of blueberry, is the most effective antioxidant of current nature.

summary of the invention:

Given this, be necessary to develop a kind of processing method of extracting anthocyanidin from black matrimony vine.

A kind of processing method of extracting anthocyanidin from black matrimony vine, comprise the steps:

rehydration: will deceive dried fruit of lycium barbarum and soak 4 hours rehydrations with pure water in material-compound tank, every 100 kilograms of black matrimony vines add 30 kilograms of pure water);

broken: by spiral beating pulp grinder fragmentation for the black matrimony vine after rehydration; After the epidermis fragmentation, be the wax layer fragmentation, contact area is large, therefore anthocyanidin extracts soon;

gel: to the pure water that adds 4 times of black dried fruit of lycium barbarum weight in the black matrimony vine after fragmentation, put into extractor, be warming up to 34 ~ 38 ℃, add the albumen prozyme of 1g/L, insulation is warming up to 40 ~ 44 ℃ of insulations 1.5 hours after half an hour, be warming up to 78 ~ 82 ℃ of insulations 10 minutes, then be cooled to below 30 ℃, gel solid material is separated out;

vacuum extraction: by step

move in circles vacuumizing filtration three times of the black medlar liquid obtained, discharge waste residue, obtains extracting solution;

uniform filtration: extracting solution is sheared macrobead by shears, be pumped to afterwards superhigh-voltage homogenizing machine, the high-speed stirring rotation mixes, and through 80 ~ 120 order cottonseed cakes, filters, and adds afterwards 1g/L zymin insulation 4 ~ 8 hours;

economic benefits and social benefits are concentrated: by step

the solution obtained is squeezed into economic benefits and social benefits and is vacuumized concentration tank, controls vacuum tightness 8Mpa, vacuumizes concentrated 6 hours under 60 ~ 65 ℃, obtains thick anthocyanidin inspissated juice.

sterilization packaging: the anthocyanidin inspissated juice is squeezed into to the instantaneous sterilizing device, 92 ℃ of lower sterilizings 4 minutes, be cooled to rapidly 32 ~ 42 degree packs.

Perhaps, step

also can vacuumize 8 hours under 8 ~ 10Mpa by vacuumizing drying machine at 60 ~ 72 ℃, add afterwards starch 30% to carry out spraying drying, then carry out micronizing, obtain powdery anthocyanidin.

Step

in the albumen prozyme also can use polygalacturonase to replace.

The present invention adopts press type low-temp low-pressure technique to fill the black matrimony vine pulp of part separation, and free from foreign meter in fruit juice concentrate, precipitation is few, and simultaneously, the technique that the present invention adopts mostly is physical method, and chemical reagent is few, does not contain sanitas.

embodiment:

rehydration: will deceive dried fruit of lycium barbarum and soak 4 hours rehydrations with pure water in material-compound tank, every 100 kilograms of black matrimony vines add 30 kilograms of pure water);

broken: by spiral beating pulp grinder fragmentation for the black matrimony vine after rehydration; After the epidermis fragmentation, be the wax layer fragmentation, contact area is large, therefore anthocyanidin extracts soon;

gel: to the pure water that adds 4 times of black dried fruit of lycium barbarum weight in the black matrimony vine after fragmentation, put into extractor, be warming up to 34 ~ 38 ℃, add the albumen prozyme of 1g/L, insulation is warming up to 40 ~ 44 ℃ of insulations 1.5 hours after half an hour, be warming up to 78 ~ 82 ℃ of insulations 10 minutes, then be cooled to below 30 ℃, gel solid material is separated out;

vacuum extraction: by step move in circles vacuumizing filtration three times of the black medlar liquid obtained, discharge waste residue, obtains extracting solution;

uniform filtration: extracting solution is sheared macrobead by shears, be pumped to afterwards superhigh-voltage homogenizing machine, the high-speed stirring rotation mixes, and through 80 ~ 120 order cottonseed cakes, filters, and adds afterwards 1g/L zymin insulation 4 ~ 8 hours;

economic benefits and social benefits are concentrated: by step the solution obtained is squeezed into economic benefits and social benefits and is vacuumized concentration tank, controls vacuum tightness 8Mpa, vacuumizes concentrated 6 hours under 60-65 ℃, obtains thick anthocyanidin inspissated juice.
