Pinenut polypeptide beverage and preparation method thereof
Technical field the present invention relates to a kind of drink, particularly is the drink of primary raw material with the pinenut.
The background technology pinenut is a kind of food that contains multiple nutritional components.Eat for convenience and store, people have designed the scheme that is processed into beverage, as on December 29th, 1993 Gazette of Patent for Invention disclosed a kind of<all-natural pine nut milk and pinenut breast preparation method (application number 93103388.8) it be to adopt pinenut as primary raw material, add additive and water such as sugar, salt, emulsifying agent, stabilizing agent, antioxidant, fumet then again, can obtain all-natural pine nut milk through main programs such as the enzyme that goes out, peeling, defibrination, ultra-fine high pressure homogenate, sterilizations.Its weak point is that the protein of pinenut is to exist with big molecular forms, is difficult for being absorbed by human body.
Summary of the invention the present invention is to be primary raw material with the pinenut, through a kind of polypeptide beverage that enzymolysis is made, protein content in this drink 〉=0.5%, solubility in acid peptide yield 〉=25%, fat content 〉=0.6%, soluble solid content 〉=6%, remaining amount are water.
Preparation method's technological process of drink of the present invention is referring to Fig. 1, and concrete operations are as follows:
One, primary raw material and processing: main material of the present invention is the pinenut that shells.
1, selection: choose and remove the rotten pinenut that shells that goes rotten.
2, preliminary treatment: with will shell the pinenut of underwear of 0.2% sodium hydroxide solution is to soak 4 minutes under 80 ℃ the condition in temperature, and water is rinsed well then.
3, defibrination: adopt one of following method to carry out defibrination, control pinenut: water=1: 15 (weight ratio)
1. adopt conventional fiberizer, pinenut is mixed with 1: 5 weight ratio with water, use paste mill grinding, slurries are crossed 100 mesh sieves, the water of equivalent carries out defibrination second time when getting filter residue and adding with defibrination for the first time, and slurries are crossed 100 mesh sieves, get filter residue add again with the first time during defibrination water of equivalent carry out defibrination for the third time, slurries are crossed 100 mesh sieves, and it is stand-by to merge three defibrination gained filtrates.
2. use three roller stone mills that pinenut is levigate, add then pinenut and water with 1: 15 weight ratio again by the colloid mill defibrination, then slurries are crossed 100 mesh sieves, it is stand-by to get filtrate.
Two, auxiliary material and processing: it is that pinenut is made raw material that the present invention can all adopt primary raw material, but because the fatty amount of pinenut is higher, therefore adding too much pinenut easily makes fat floating, increases cost simultaneously again.For guaranteeing protein content in the finished product, can adopt casein, collagen and soybean to replenish as auxiliary material.Wherein casein is mammiferous dairy products, and it contains rich in protein, and now as the important source of physiologically active peptide, it can become various immune peptides through enzyme hydrolysis, and as the antithrombotic peptide, the mineral element binding peptide is CPP (CPP).Collagen is the main component of animal connective tissue, its enzymolysis is become collagen polypeptide, the molecular weight ratio collagen is much smaller, being beneficial to human consumption absorbs, and it has functions such as fine solubility, absorbability, foaming characteristic, water imbibition, not only can be used as foodstuff base material but also can be used as NMF, emulsion stabilizer and blowing agent.When replenishing casein or collagen, need to take out a certain amount of pinenut filtrate, heating makes temperature to 50 ℃, then added casein or collagen is beaten repeatedly, is mixed with mixer, last and filtrate merging.The method of replenishing soybean is: earlier soybean is handled, its method is as follows: soybean is through impurity elimination, places 95 ℃ of water enzyme that carries out going out in 5~20 minutes to handle.Utilize peeling machine that skin of beancurd is taken off, slough lipoxidase contained in the skin of beancurd simultaneously, remove beany flavor and bitter taste.Place the water of 3 times of soybean weight to soak then, fully hydration.The adding soybean is measured 6 times water mill slurry after pulling soybean out, crosses 150 eye mesh screens.Adopt 19.6~26.7KPa vacuum to carry out deodorization, moment boils off bad smell, and the product that obtains is the soybean slurries, wherein contains abundant soybean protein.
Three, enzymolysis
1, the enzyme that enzymolysis adopted be protease as
Bromelain (500,000 units/gram enzymes are lived)
As1398 neutral proteinase (180,000 units/gram enzymes are lived)
COROLASE PN-L (200,000 units/gram enzymes are lived)
2, the consumption of enzyme is represented with following formula
Wherein: W
Enzyme---enzyme dosage
W
Former---protein quality in the raw material
3, the consumption of raw material can adopt following raw material for guaranteeing protein content 〉=0.5% in the finished product
1. raw material all is the pinenut that shells: the pinenut consumption calculates with following formula
2. raw material is pinenut and casein mixture: the pinenut consumption that shells is 1~2% * finished weight, casein consumption 〉=0.4% * finished weight.
3. raw material is pinenut and collagen mixture: the pinenut consumption that shells is 1~2% * finished weight, collagen consumption 〉=0.4% * finished weight.
4. raw material is pinenut and soybean mixture, and the pinenut consumption that shells is 1~2% * finished weight, soybean consumption 〉=1.5~2% * finished weight.
4, enzymatic hydrolysis condition
30~50 ℃ of temperature, 1~2 hour time, pH value 7.5~8
5, the enzyme that goes out: with the product behind the enzymolysis 80~90 ℃ of insulations 10~15 minutes
Four, allotment
1, allotment:, in enzymolysis product, add 4~6% white granulated sugars and 0.1~0.3% molecule distillating monoglyceride and 0.1~0.3% octadecyl sodium lactate with respect to finished weight for adjusting beverage mouthfeel.
2, dilution, filtration: thin up is crossed 300 mesh sieves then to the concentration of predesignating in material.
3, homogeneous: the material after will filtering is heated to 62~80 ℃ temperature, twice of 25~30MPa homogeneous.
4, sterilization can: the material that will cross through homogeneous was through 137~140 ℃ of ultra high temperature sterilizations 3~8 seconds, and outlet temperature is controlled at 80~90 ℃.Can be adopted dual mode, and a kind of is the material behind the ultra high temperature sterilization to be squeezed into the sterile filling production line with pump carry out can, and what obtain promptly is finished product.Another kind of mode is that the material hot filling is gone in the heatproof container, and again through 121 ℃ of temperature sterilizations 30 minutes, what obtain promptly is finished product after sealing.
Pinenut polypeptide beverage is to decompose the product that makes through enzyme by pure pinenut albumen, pinenut albumen and casein, pinenut albumen and collagen, pinenut albumen and soybean protein.Its many peptide species molecular mixing after by proteolysis is formed, and its nutritive value equates with the protein of constitutive material.But compare just like feature with traditional pinenut drink:
1. Pinenut polypeptide beverage is is easily digested and assimilated;
2. can provide energy to body rapidly;
3. there is not protein denaturation, no residue, molecular weight is little, and is soluble in water;
4. do not produce precipitation under acid condition, solution viscosity is little, is heated not solidify;
5. the polypeptide mass-energy in the Pinenut polypeptide beverage combines with cholic acid in the body, has functions such as the human serum of reduction cholesterol, hypotensive and fat-reducing.
