Barley germ rice and processing method thereof
Technical field
The present invention relates to a kind of hullessbarley seed be made the processing method of barley germ rice and the barley germ rice by the acquisition of described method.
Background technology
Highland barley is a kind of of barley, claims hull-less barley, highland barley, Huaihe River wheat, Mi Damai again.At the extremely frigid zones of 4200~4500 meters of height above sea level, highland barley almost is unique crop.
According to supplement to the Herbal record, highland barley is used as medicine " flavor saltiness Pingliang ", its major function be the therapeutic method to keep the adverse qi flowing downward wide in, strong lean power, dehumidifying sweating, antidiarrheal.Record in the Tibetan medicine ancient books and records " Tibetan medicine will " " brilliant pearl book on Chinese herbal medicine ", white highland barley flavor is sweet, and property is rough, cool, heavy, and is uncomfortable in the stomach of food back.The effect therapeutic method to keep the adverse qi flowing downward, establishing-Yang is controlled and is had oil material, Baconic's disease, red crust disease, flu in the urine.Blue highland barley is controlled infantile lung heat, intestinal colic; Control tuberculosis after the stir-fry; Black highland barley is controlled impetigo.
The modern scientific research data shows, be grown in the highland barley in high and cold areas such as Qinghai-Tibet Platean, because Special geography position, ecological environment and weather conditions (high and cold, pollution-free, day and night temperature is big etc.), nutritional labeling is abundant, general kind contains protein 10%~14%, reaches as high as 20.3%; Fatty is 1.5%; Contain thiamine (Cobastab in every 100g highland barley flour
1) 0.32mg, riboflavin (Cobastab
2) 0.21mg, niacin 3.6mg, vitamin E 0.25mg, beta glucan 6%~8.62%, these materials and health and growth all have relation.
At present, biomedical boundary generally believes that beta glucan has four big physiological actions such as gut purge, adjusting blood sugar, reduction cholesterol, raising immunity, and its angiocardiopathy preventing and antineoplastic action are also by extensive concern.44 above old men at the age of one hundred years old are just arranged among the average every million people in the Tibet of high and cold anoxic, are one of maximum provinces and regions of China centenarian, and the outstanding health care of highland barley is one of key factor of Tibetans' longevity.
From the angle of traditional food processing, mainly be to be applied to make barley wine to traditional processing and utilization of highland barley, make beer or liquor with highland barley by fermentation as raw material; The grain processed product of highland barley mainly is hullessbarley seed to be fried wear into the zanba, roasted qingke barley flour that powder is made, and highland barley is also as the usefulness of feed in addition.
Chinese patent application CN 1586221A discloses a kind of highland barley biscuit and preparation method thereof, and this method comprises highland barley flour, strong refined flour, vegetable oil, refined salt, white granulated sugar, leavening agent etc. through steps such as batching, moulding, oven dry, oil spouts.Be processed into the biscuits that is rich in beta glucan, crude protein.
Chinese patent application CN1718104A has instructed a kind of highland barley health care food, by konjaku flour, highland barley flour, wheat flour, edible wet goods are mixed well, moulding forms.
Though these methods have utilized the nutritional labeling of highland barley to make various food, what they used is that highland barley flour is as raw material.According to the study, there are many defectives in highland barley flour as the raw material of food processing.Though highland barley flour has abundant beta glucan, glutenin is lower with other binding proteins on the other hand owing to it, the gluten content deficiency.Thereby the highland barley food mouthfeel of making is more solid, harder, can not liked by the consumer.
Chinese patent application CN 1799402A discloses a kind of preparation method of particle product of highland barley, this method comprises highland barley raw material screening, removal of impurities, takes off epidermis chaff skin, the highland barley meat that separates is added water softening, deironing and press forming, and made particle is flat sheet.It is said that made goods can be suitable for boiling into the congee meal.
Though said method uses highland barley grains as raw material separately, it pays attention to provide the nutrition of highland barley goods, has ignored mouthfeel of highland barley own and the relatively poor characteristics of edible quality.Make that the highland barley food of making is coarse, viscosity is bigger.
Therefore, as a whole, the food palatability that highland barley is made is poor, coarse mouthfeel, and these factors make present technology that highland barley can only be embodied its traditional nutritional benefits as the application of food, and have been subjected to very big restriction aspect mouthfeel.
Therefore, the present invention will solve the shortcoming of present highland barley as raw materials of food processing, after making that highland barley is handled by processing of the present invention, when keeping the original nutritional labeling of highland barley, improve the mouthfeel of highland barley, it is fine to make it to become palatability, the raw materials of food processing of taste good, thus enrich the kind of highland barley food.
Summary of the invention
The purpose of this invention is to provide a kind of processing method of barley germ rice, may further comprise the steps: hullessbarley seed is soaked; With the hullessbarley seed boiling after soaking; With the hullessbarley seed drying after the boiling, remove the wheat bran of hullessbarley seed and make thick highland barley rice then; Thick highland barley rice is carried out cleaning polishing to be handled.
One of characteristics of the present invention are the traditional processing thought that changes highland barley, and hullessbarley seed is processed into highland barley rice.Two of characteristics of the present invention are to have prevented that in the highland barley rice process, plumule causes the loss of nutriment along with wheat bran removes.By boiling the nutriment in the barley germ is diffused in the highland barley endosperm, make that plumule should not remove in the highland barley rice processing, the rice that makes with barley germ rice is when keeping the original nutritional labeling of highland barley, greatly improved the mouthfeel of highland barley rice, it is glutinous flexible to make it to wriggle more.
Therefore, method of the present invention comprises hullessbarley seed is soaked; Hullessbarley seed boiling after will soaking then.
Before soaking, can choose the raw material of hullessbarley seed, select the raw material of the highland barley seed of those full seeds as processing.The process of selection hullessbarley seed can comprise the highland barley seed of selected full seed, removes flat grain, variegated grain; Remove the impurity such as stone, silt or other cereal that mix in the hullessbarley seed.Hullessbarley seed can be selected any in white highland barley, yellow highland barley, blue highland barley, the black highland barley.
The immersion of hullessbarley seed can be carried out in normal-temperature water, preferably soaks in hot water.Immersion treatment not only can the various active components of passivation, its storage stability is improved greatly, and make water-soluble nutrient substances such as contained B family vitamin of plumule and cortex and inorganic salts, most of with moisture penetration to grain of rice inside, increase the nutritive value of preboiled rice.In addition, the effect of immersion is also to make hullessbarley seed boiling easily in step subsequently.In a preferred scheme, heat water to 80~90 ℃, put into hullessbarley seed then, keep water temperature to remain on about 70 ℃, soaked 3 hours.
Then, with the hullessbarley seed boiling, make it slaking.This process of cooking can adopt this area mode commonly used to carry out.Boiling is preferred in closed container, for example at 0.5kgf/cm
2In the boiling vessel of pressure, boiling 20 minutes.
Hullessbarley seed after the boiling needs drying, makes it moisture and descends.Moisture is reduced to about 14% and is advisable.Drying can adopt any way, for example air-dry, oven dry, drier drying etc. or be used in combination.A kind of optimal way of this dry run is to adopt stage drying, adopts rapid dry process earlier, makes moisture drop to 20%, enters then slowly, and low temperature is dry at a slow speed, and moisture is dropped to about 14%, can reach even and mild drying effect like this.
Therefore, method of the present invention comprises after the boiling and drying, and the wheat bran of hullessbarley seed is removed, and makes thick highland barley rice.
The wheat bran of hullessbarley seed separates and can finish by the plant equipment or the manual method of routine.Rubbing leather method for example.
When removing wheat bran and plumule, the particle that processing produces together can also be removed.
By above-mentioned steps, make thick highland barley boiling rice.Carry out fine finishining on this basis, promptly highland barley rice is carried out cleaning polishing and handle.
