Description

A kind of preparation method of barley health-care solid beverage
Technical field
The invention belongs to beverage/food technical field, and in particular to a kind of preparation method of barley health-care solid beverage.
Background technology
Barley is that grass family Hordeum is annual, gives birth to or perennial herb crop in more year, and alias tries to gain wheat, meal wheat, barebacked wheat. Used as one of world's staple food crop, its food therapy function is already recognized barley by people.《Compendium of Materia Medica》Say:Barley is sweet It is salty cool, there are a clearing away heat and promoting diuresis, and the effect of stomach intestines wide.《Mediate class is adjusted to compile》Think:Barley is mild-natured cool, helps stomach Qi.For wheat is won in face, and Without scorching.Moderns like wheat, and dare not or would not speak up barley, surprisingly health.《It is good to help book on Chinese herbal medicine》Upper record:The hair of long term usage is not white, very benefit People, therefore barley cures mainly dysphoria with smothery sensation of relieving summer heat, and has QI invigorating, in tune, qi-restoratives beauty treatment, the work(of disperse accumulations feed.
Contain various functional components in barley, mainly there is several amino acids, beta glucan, alpha-tocotrienol, flavonoids Compound, polyphenol compound, ergot class compound etc..Having 75% in barley endosperm cell membrane is made up of beta glucan, β-Portugal The research report of glycan physiological function is concentrated mainly on reduction cholesterol and hypoglycemic two aspect.Beta glucan is to animal and human body Immunity function have a facilitation, can growth promotion, build up health, improve resistance against diseases.
Alpha-tocotrienol can be eliminated or quenching activity oxygen radical, prevent the chain reaction of lipid peroxidation, so that With oxidation resistant function.There is research to show, during rat liver microsome membrane lipid peroxidatio, alpha-tocotrienol Antioxidation activity protects cytochrome P much stronger than alpha-tocopherol450Ability it is also stronger than alpha-tocopherol, tocotrienols can be with Rat heart is protected from oxidative damage.The antioxidation of tocotrienols has important at the atherosis aspect of prevention of arterial Meaning.Alpha-tocotrienol can reduce cholesterol, and this is the earliest report of tocotrienols reduction cholesterol, causes people Concern.Further study showed that, alpha-tocotrienol can effectively suppress the activity of HMG-COA reductases.HMG-COA Reductase is the rate-limiting enzyme of internal cholesterol biosynthesis, it is suppressed that its activity also may refrain from the synthesis of cholesterol.Cell experiment Prove that tocotrienols has the function of suppressing cholesterol biosynthesis with zoopery.
Flavone compound based on catechin, myricetin, Quercetin, Kaempferol, with antibacterial, it is antiviral, antitumor, Suppress cholesterol increases with Lipid, suppresses effect that blood sugar rises.
Baked barley tea is typically barley frying into sallow, before eating, it is only necessary to can leach strong perfume (or spice) with brewed in hot water Tea.Barley is prepared into the trend that a kind of easily tea-drinking is current barley food development through deep processing.Chinese patent CN104171170A provides a kind of preparation method of instant baked barley tea, with high-quality barley as raw material, by rotating cone destilling tower Method extracts the modes such as the baked barley tea slurry enzymolysis processing after fragrance elite, extraction, elite backfill and spray drying and prepares instant barley Tea.The invention has been sufficiently reserved the active ingredient in barley, and inherits the local flavor of barley giving off a strong fragrance juice alcohol.But spray drying Temperature it is higher so that the alpha-tocotrienol in baked barley tea is largely oxidized, made big simultaneously because the presence of hordenine Wheat tea mouthfeel is more puckery, and consumer's drinking experience is not good.
The content of the invention
The invention provides a kind of preparation method of barley health-care solid beverage, barley in made barley health-care solid beverage Functional component content it is higher, and functional component activity it is higher, beverage mouthfeel is more preferably.
The technical proposal for solving the technical problem of the invention is:
A kind of preparation method of barley health-care solid beverage, comprises the following steps:
(1) high-quality barley cleaned, dry, bakeed in 120-150 DEG C and remove within 30-50 minutes moisture, then be grinding to obtain big Flour, after being gelatinized 20-40 minutes in addition boiling water, is cooled to room temperature, obtains barley slurry.Bakeed by low temperature and replace high temperature to fry System, preferably, functional component is because of high temperature deactivation on the other hand being prevented effectively from barley for the color and luster of one side barley tea-drinking.By barley Powder is first destroyed amylum body therein through boiling water gelatinization, and crystal structure disappears, and becomes amorphism starch, now barley particles Expansion.
(2) step (1) gained barley slurry is used into complex enzyme in 40-60 DEG C, under PH5-6, is digested 6-10 hours, through boiling water The expansion barley particles hydrolysis result of gelatinization is more preferable.
(3) step (2) gained enzymolysis liquid is heated to boiling, is incubated the 5-10 minutes enzyme that goes out, be cooled to room temperature, centrifugation is big Wheat clear liquid;
(4) step (3) the gained barley stillness of night is used into chloroform extraction, takes supernatant liquor, in 60-80 DEG C of vacuum drying After 8-10 hours, then pulverize.Contain a small amount of hordenine in barley, make it have acerbity, influence the mouth of barley tea-drinking Sense, barley clear liquid is extracted using trichloroethanes, and further the hordenine in removal barley clear liquid, improves the mouth of barley tea-drinking Sense.
Preferably, pearling cone meal described in step (1) is 1 with the mass ratio of boiling water:20-30.
Preferably, complex enzyme is made up of cellulase, carboxy-lesterase and AMS described in step (2), the fibre The mass ratio of the plain enzyme of dimension, carboxy-lesterase and AMS is 1:2-5:1.5-3.Using complex enzyme coordinated enzymatic hydrolysis, compared to single Enzyme is digested, and has the advantages that hydrolysis temperature is low, the time is short, efficiency high.AMS and cellulase are constantly by its hydrolysis Carboxy-lesterase provide non-reducing end, effectively increase its concentration of substrate, at the same carboxy-lesterase again constantly consumption AMS and The product of cellulase degradation, promotes the two hydrolysis, so as to improve enzymolysis efficiency, improves product purity.
Preferably, the slurry of barley described in step (2) is 1 with the mass ratio of complex enzyme:0.1-0.3.
Preferably, the rotating speed being centrifuged described in step (3) is 1200-1500r/min, centrifugation time is 8-15 minutes.
Preferably, the barley stillness of night described in step (4) is 1 with the mass ratio of trichloroethanes:8-10.
Beneficial effects of the present invention are:
1st, the present invention is bakeed using low temperature and substitutes high temperature frying, effectively reduces the functional component in barley tea-drinking because of high temperature Inactivation, the reduction cholesterol and effect of lowering blood sugar of made barley health-care solid beverage are more preferably.
2nd, the complex enzyme zymohydrolysis constituted using cellulase, carboxy-lesterase and AMS, with hydrolysis temperature is low, the time Short, efficiency high advantage.
3rd, solid beverage is finally reduced using hordenine in chloroform extraction method removing barley health-care solid beverage Sour and astringent sense, makes its mouthfeel more preferably.
