A kind of preparation method of barley green
One, technical field: the present invention relates to barley green finished product preparation method technical field, more particularly relating to the tender seedling of highland barley is the preparation method of the barley green of raw material.
Two, background technology: Barley Greeg is the abbreviation of wheat seeding spire juice.The nutrition of wheat seeding and medical value were just found as far back as China Ming Dynasty.Put down in writing according to Compendium of Material Medica: wheat seeding is hot cold nontoxic.Cure mainly wine poison sudden-heat, wine subcutaneous ulcer order Huang.Separate handleless cup poison, liquor filter clothes again, disease fanaticism when separating is moved back septum pectorale heat, and sharp small intestine is made the vegetarian food, very beneficial color.Modern biochemistry studies show that the wheat seeding metabolism before the heading is active, and the potassium that is richly stored with, magnesium, iron, calcium, copper, selenium, manganese etc. are kept the mineral matter of cell health growth, contain and enrich vitamin A, C, B
6And kind of needed by human but the bioactivator that can not synthesize in vivo surplus the superoxide dismutase (SOD) etc. 200.
In recent years, medical science, nutrition research and clinical practice both at home and abroad prove, effects such as Barley Greeg has the intestines and stomach of protection, reconciles digestion and absorption function, promotes metabolism, protects liver, anticancer, balancing blood fat and blood sugar, eliminating toxin.Take for a long time, can make us body keep fit, energetic, reduce disease and take place, can be used as the auxiliary dietotherapy instrument of the not good enough and whelk of chronic digestive system disease, liver diseases, high fat of blood, diabetic and skin physiology state, also can be used for replenishing vitamin A, C, the E of needed by human and increasing chlorophyllous intake, is a kind of good function health food.
Highland barley is being commonly called as of Qinghai-Tibet hull-less barley, belongs to one of mutation of grass family Hordeum barley on Plant Taxonomy, has precocity, cold-resistant, characteristics such as anti-carbuncle thin, stable yields and wide adaptability.As everyone knows, be grown in the hull-less barley-highland barley of Qinghai-Tibet Platean, because growing environment is with fresh air, away from atmosphere pollution, the sunshine-duration is lacked 3.5 hours than other regional as many as, the active component height.Therefore, have reason to believe that the highland barley seedling is more preferably as the raw material of producing Barley Greeg than other wheat classes.
At present, existing is to have defectives such as crushing juice rate is low, the wheat seeding resource is not fully utilized among the Barley Greeg preparation method that makes of raw material with the wheat wheat seeding, has seriously hindered the Barley Greeg Products Development and has popularized.
Three, summary of the invention:
The object of the present invention is to provide a kind of barley green preparation method of high crushing juice rate, the product that makes has the yield height, the active component advantages of higher.This preparation method is realized by following processing step:
1, preliminary treatment: with growing height is to select after the bright highland barley seedling of 25~40cm extracts, and removes withered leaf seedling, earth and weeds.The seedling of preferably select no air pollution, no soil pollution for use, not using chemical fertilizer.The highland barley seedling water of selecting is cleaned up, stand-by after carrying out blanching under 80~95 ℃ of temperature, the condition of 1~5 minute time to protect the look processing.
2, making beating: the highland barley seedling is processed into slurries.In actual production, can select plant equipment such as beater, colloid mill for use.
3, enzymolysis: in the highland barley bacterin, add cellulase, under certain condition degradation treatment.The enzymolysis parameter is: the mass ratio of cellulase and highland barley bacterin is 1: 1000~10000,30~60 ℃ of temperature, and pH value is 3.5-6, stirs enzymolysis time 0.5~4 hour.The available hydrochloric acid of the adjusting of pH value, acetic acid or other acid are regulated.
4, squeeze the juice: the highland barley bacterin liquid that enzymolysis is good places juice extractor to squeeze the juice, and the water infiltration of 0.8~1.5 times of weight of residue obtained usefulness residue weight is squeezed the juice after 0.5~1.5 hour once more, merges gained highland barley seedling juice twice, and is stand-by.In actual production, preferentially select spiral juice extractor for use.
5, filter: adopt filter plant that highland barley seedling juice and insoluble residue are further separated.In actual production, preferentially select filter centrifugal for use.
6, drying: make the moisture in the highland barley seedling juice reduce to 7~10% with drying equipment.In actual production, preferentially select spray-drying for use.
7, sterilization packaging: with the highland barley seedling powder of preparation with microwave or Co
60Sterilization, vacuum packaging.
Active component leaching rate and barley green productive rate significantly improve among the present invention, and active component that has such as SOD improve about 40%, and the Barley Greeg productive rate improves about 30%.This is because highland barley seedling cell membrane mainly is materials such as cellulose, hemicellulose and lignin fine and close the composition, and conventional expressing process can't destroy the cell wall skeleton structure, and active ingredient is separated out abundant inadequately in the cell.Behind the enzymolysis, the skeleton structure of cell membrane is degraded step by step by cellulase, is beneficial to separating out of active component.Processing technology has intactly kept the natural nutrition composition, particularly active ingredient in the highland barley seedling tender leaf.
Four, the specific embodiment
