Description

A kind of liquid diary product that adds tartary buckwheat powder and naked oats flour and preparation method thereof

Technical field

The present invention relates to dairy product processing field, particularly, the present invention relates to a kind of liquid diary product that adds tartary buckwheat powder and naked oats flour and preparation method thereof.

Background technology

Duck wheat is one of traditional small coarse cereals of China, mainly is distributed in ground such as mountain area, China southwest, the Yunnan-Guizhou Plateau and Shaanxi, Shanxi, and it has drought-enduring, cold-resistant, acidproof, anti-lean, adaptability is strong, lack growth period characteristics.The protein content of duck wheat is higher, generally about 10%, apparently higher than rice, wheat, corn and Chinese sorghum; Its protein is formed and is different from general cereal crops, mainly is made up of glutelin, water-soluble albumin and salt dissolubility globulin, is rich in arginine, lysine, tryptophan, histidine, and other cereal protein is had good complementarity.The essential amino acids content of duck wheat protein matter is abundant, proportion of composing is more reasonable, the utilization that is easy to be absorbed by the body, and its biological value, BV is 93, and the aleuronat biological value is 63, the rice protein biological value is 67.The content of fatty acid of duck wheat is generally 2.1%～2.8%, mainly be oleic acid, linoleic acid and a spot of leukotrienes that can prevent dry skin, blood urine, fatty liver diseases, these unrighted acids have the stercorin that promotes in the ight soil and the Excretion of cholic acid, low-density lipoprotein is also reduced, relatively HDL then rises, and effect for reducing blood fat is arranged.The unique distinction of duck wheat vitamin is to contain the Flavonoid substances that other Cereals does not have, accounting for more than 2% of dry weight, mainly is rutin wherein, accounts for 80%, rutin is a kind of polyhydric phenols, belong to rutinoside, human body is had different physiological roles, have the resistance of keeping capillary, reduce its permeability and fragility function, promote hyperplasia and prevent the aggegation of haemocyte, and the effect of hemangiectasis, can improve cardiovascular system, suppress malignant growth and cancer.In addition, duck wheat is at anti-diabetic, anti-inflammatory, treatment ulcer and respiratory tract system disease etc. had good effect.In addition, the content of the vitamin B1 in the duck wheat, B2, nicotinic acid also is higher than other staple food crop.The duck wheat content of mineral substances is very abundant, and iron, calcium, copper, zinc, magnesium, potassium, chromium, selenium, iodine equal size all are much higher than cereal crop; Iron content is 3～20 times of wheat; The existence of selenium is particularly valuable, and the F082 buckwheat Se content that wherein originates in Shanxi reaches 73.8lg/100g.Selenium is the insulin cell trace elements necessary, and Wheat Protein, can regulate immune function of human body, is important cancer-resisting substance, and selenium also helps to mediate the poisonous element in the human body.Magnesium has the effect of regulating cardiac function, is to keep heart normal function and the necessary material of structure.Contain more dietary fiber in the duck wheat, the glucan of colloidal substance especially, these dietary fibers have positive effect to preventing and treating diabetes and high fat of blood.

Duck wheat is a kind of good nutrient source, can be used as pure natural, pollution-free green food, can be used for developing the base-material of health food again.In recent years, along with the raising of people's level of cultural life, people pay much attention to health food and dietary function thereof.This conventional food of duck wheat more and more is subjected to people's favor, and the novel foodstuff as diseases prevention, the food and medicament dual-purpose of curing the disease can develop and utilize from many aspects.

Naked oats also claim oat, and salt tolerant becomes, and is anti-high and cold, should do in the knob field cultivation early.Naked oats just can be processed naked oats flour after threshing.Per 100 grams of naked oats flour contain protein 12.2 grams, lipase 37 .2 gram, carbohydrate 67.8 grams, dietary fiber 4.6 grams, carrotene 20 micrograms, 3-Hydroxyretinol microgram; Contain eight seed amino acids of needed by human, its content of vitamin E also is higher than rice and fine flour.Naked oats are sweet in flavor and warm in property, have strengthen the spleen and stomach, laxation is hastened parturition, end abnormal sweating and hemostasia effect, and is all-ages, is more suitable for the elderly and patients with diabetes mellitus.Water-soluble dietary fiber contained in the naked oats reduces the generation cardiovascular disease risk by reducing harmful low-density lipoprotein sterol levels, helps to control blood sugar, reduces cholesterol, hypotensive.

Milk is nutritious, digest and assimilate easily, inexpensive, instant, is near perfect food, and person " white blood " is optimal wholefood.Comprise amounts of protein in the milk, be mainly casein, albumin, globulin etc., 8 seed amino acids of needed by human are arranged in the 20 contained several amino acids, milk proem matter is complete protein, and digestibility is is easily digested and assimilated up to 98%, is desirable wholefood.

At present, duck wheat can be used for making duck wheat biscuit, duck wheat bread, duck wheat vermicelli, duck wheat macaroni, duck wheat instant noodles, duck wheat cake etc. on the market.But, edible these duck wheat goods of people do not come into one's own, main cause is that the edible common tartary buckwheat powder viscosity of people is big, poor processability, coarse mouthfeel, and have certain bitter taste, processing and eating is very inconvenient, present domestic buckwheat flour goods buckwheat content is substantially between 20%～40%, and mouthfeel is relatively poor, makes the function factor of buckwheat be difficult to play a role in diet.

For naked oats, naked oats are cold in nature, need could take food through " three is ripe ", namely earlier naked oats fried, and wear into powder, and are bold and vigorous ripe with boiling water naked oats flour again, make various styles after becoming reconciled and cook, and could eat.As seen, the processing of naked oats food is but rather time-consuming, has limited the edible naked oats food of many people, has also limited the sale of naked oats food.

As seen, all there are certain unfavorable factor separately in duck wheat, naked oats, thereby have limited the edible of them and sold.In the market, also do not see the product that duck wheat, naked oats and milk are combined.How duck wheat, naked oats, milk three being mixed, realize the perfect combination of three's local flavor, is a great difficult problem.Reason mainly contains: (1), can cause a large amount of disappearances of nutritional labeling, and can not form good local flavor in manufacturing process if just utilize simple process to make tartary buckwheat powder, naked oats flour; (2) tartary buckwheat powder, naked oats flour have unique separately local flavor, just simple the adding, are difficult to realize coordinating with the milk local flavor; (3) will tartary buckwheat powder, naked oats flour adds the stability that how to guarantee dairy products after the milk, the come-up of bleed, fat does not take place in shelf life and still can keep good mouthfeel and local flavor etc.Therefore duck wheat, naked oats and milk are combined and to be overcome above-mentioned problem.

Summary of the invention

The object of the present invention is to provide a kind of liquid diary product that adds tartary buckwheat powder and naked oats flour.

The preparation method of the interpolation tartary buckwheat powder that a further object of the present invention is to provide above-mentioned and the liquid diary product of naked oats flour.

According to the liquid diary product of interpolation tartary buckwheat powder of the present invention and naked oats flour, based on 100 weight portion raw materials, it comprises:
