Description

A kind of corn germ drink and preparation method thereof

Technical field

The present invention relates to technical field of beverage, the present invention relates to a kind of corn germ drink and preparation method thereof in particular.

Background technology

Corn is one of northern China staple crops, and maize germ accounts for the 8-10% of corn, and main nutrient composition really accounts for more than 70% of whole corn.Maize germ censorship Beijing City Nutrient Source Inst is carried out among the result of trophic analysis: every 100g maize germ contains protein 20.5g, fatty 28.6g, carbohydrate 40.8g.Contain microelements of calcium 5.9mg, iron 8.5mg, zinc 9.0mg contains VB11.48mg, the particularly outstanding 9.86mg that reaches of VB20.42mg, VE content.Maize germ is described as " natural VE nutrient source " abroad with other grain germ, and VE content is far above meat and other cereal in the plumule, and pigment granule in the pigment in the cell improved skin elasticity when VE can reduce aging, alleviated sexual gland atrophy etc.; Plumule is again the person of being rich in zinc in the plant, and zinc has participated in DNA, RNA in the cell division and the basic process of duplicating, and it can promote teen-age growing and intelligence development, to person in middle and old age's anti-senility tool good health care effect.Also contain a large amount of lecithin, grain alcohol in the plumule and be not full of and aliphatic acid, these materials can suppress fat in the absorption of small intestine and the absorption again of bile acid, reduce the synthetic of cholesterol thereby have, and can prevent artery sclerosis, reduce blood lipid level, regulate effects such as human immunity.

Maize germ is used for extracting grease mostly in recent years, but utilization rate is not high, and only about 20%, the nutrition waste in the plumule is bigger.And utilize maize germ to make beverage, almost absolutely preserved the nutritional labeling of plumule, maize germ is fully utilized, the corn whole body has also just obtained sufficient processing and utilization, be corn deep processing and corn increment, form the corn industrial chain, a brand-brand-new way is provided, its economic benefit and social benefit are very remarkable.

E. with ground plumule slurry temperature adjustment water, stir into plumule liquid, squeeze into Stainless Steel after filtering with 200 mesh sieve cloth and add in layer steam-boiler, add d step gained auxiliary material then successively, add the water constant volume after, transfer pH value to 7.0-7.5 with the carbonic acid sodium acid carbonate, heating is boiled, and removes liquid level juice foam;

F. deployed plumule liquid is crossed 200 mesh sieves, and carry out second homogenate, the first homogenizer pressure is 20Mpa, and the second homogenizer pressure is 30Mpa, and homogenizing temperature remains between 75 ℃-80 ℃;

G. the aseptic iron pop can of plumule liquid behind the homogeneous being packed into while hot;

H. high temperature sterilization under 15 '-20 '-15 '/121 ℃ of conditions is wiped jar when being cooled to 37 ℃ of left and right sides.

Corn germ drink of the present invention contains the seven essential seed amino acids that rich in protein, vitamin and human body can not synthesize, and is outstanding with WE content especially.This beverage non-pigment, preservative free, good to eat, the pure spy of local flavor of taste.

Preparation method's technology of corn germ drink of the present invention is simple, easy operating, and cost of investment is low, is fit to generally promote.

The specific embodiment

The invention will be further described below in conjunction with the detected parameters of embodiment and invention product.

A kind of corn germ drink, form by weight percentage by following raw materials according:

Maize germ 4%

Xylitol sweetener 3.5%

Mixed emulsifying stabilizer 0.3%

Sodium acid carbonate is an amount of

Water surplus

Wherein sodium acid carbonate is used to regulate the beverage pH value to 7.0-7.5.

A kind of preparation method who prepares corn germ drink, produce the raw material of aforementioned proportion as follows:

1. dry method is carried embryo: adopt corn to carry the embryo complete set of equipments and carry out dry method and carry embryo.Through the clean free from admixture of the used plumule of sorting removal of impurities, do not have go mouldy, free from insect pests etc.

2. oven dry: the oxidative rancidity that have various enzymes in the plumule after the separation, causes plumule fat easily causes raw material rotten, so plumule was kept 20 minutes elimination or purifying enzyme activity effectively under 115 ℃, temperature.The plumule of treated mistake needs can be stored into half a year under the normal temperature.

3. grind: grind with three-roll grinder.Uniform pasty state plumule slurry is worn in corase grind, fine grinding then earlier, grind size to 20 micron.

4. allotment: before the allotment, earlier with composite sweeteners such as xylitol, mixed emulsifying stabilizer in proportion consumption dissolve with hot water respectively, and standby after 200 mesh sieves filter.Adopt dosage bunker with ground plumule slurry temperature adjustment water, stir into plumule liquid, squeeze into Stainless Steel with pump after filtering with 200 mesh sieve cloth and add in layer steam-boiler, add above-mentioned auxiliary material then successively, behind the constant volume, add an amount of sodium acid carbonate, transfer pH value to 7.0, heating is boiled, and removes liquid level juice foam.

5. homogeneous: deployed plumule liquid is filtered with 200 mesh sieves once more, carry out second homogenate with high pressure homogenizer, the first homogenizer pressure is 20Mpa, and the second homogenizer pressure is 30Mpa, and homogenizing temperature remains between 78 ℃.

6. tinning sealing: plumule liquid behind the homogeneous is packed in easy-to-draw jar of the 250ml tinplate after aseptic while hot, adopt the vacuum seamer sealing.

7. sterilization: adopt high temperature sterilization, sterilization conditions is 15 '-20 '-15 '/121 ℃, wipes jar when being cooled to 37 ℃ of left and right sides.
