Abstract

Germinated-brown-rice potato puree and a preparing method thereof are provided. The method includes germinating and culturing brown rice, pre-gelatinizing the germinated brown rice, dehydrating the pregelatinized germinated brown rice, and preparing the dehydrated pregelatinized germinated brown rice into the germinated-brown-rice potato puree. The germinated-brown-rice potato puree comprises the dehydrated germinated brown rice, potato starch, protein powder, dehydrated porphyra and salt. According to the germinated-brown-rice potato puree, the germinated brown rice, the potato starch and the protein powder are compounded scientifically, so that the characteristic that the germinated brown rice is rich in gamma aminobutyric acid is maintained, and balance matching of nutritions is achieved. By the method, taste and nutrition value of the brown rice are improved. The germinated-brown-rice potato puree can be ate only by dipping with hot water, and is free of steaming and cooking and convenient to eat.

Description

A kind of sprouted unpolished rice mashed potatoes and preparation method
Technical field
The invention belongs to food processing technology field, particularly a kind of Novel instant food---sprouted unpolished rice mashed potatoes and preparation method thereof.
Background technology
Brown rice is the caryopsis after outer protection cortex rice husk sloughed by paddy, pericarp, seed coat, the Rice Kernel that megarchidium layer is intact, and because the more mouthfeels such as interior protection cortex crude fibre, chaff wax are comparatively thick, quality is tight, boil also more time-consuming, but its slimming effect is remarkable.Brown rice is more rich in much vitamin, mineral matter and dietary fiber compared with common exquisite rice, is considered to be a kind of healthy food of green.
Brown rice is cultivated under uniform temperature, humidity, until brown rice germination to a certain extent time be dried, namely the goods be made up of the endosperm of young shoot and band chaff layer obtained are called sprouted unpolished rice.The essence of sprouted unpolished rice is under certain physiologically active metallization processes condition, and a large amount of enzymes contained by it such as amylase, protease, phytase etc. are activated and discharge, and from being converted into the enzymolysis process of free state in conjunction with state.Just because of this physiological activation process, the crude fibre shell of sprouted unpolished rice is softened by enzymolysis, partially protein is decomposed into amino acid, starch transition is carbohydrate, the organoleptic properties of food and local flavor are improved, and while remaining abundant vitamin (VB1, VB2, VB6, VC, VE), mineral matter (Mg, K, Zn, Fe), dietary fiber nutrient composition, create especially multiple have promote health and the composition of disease preventing and treating, especially gamma aminobutyric acid, IP6 equal size significantly improve.
The factors such as sprouted unpolished rice is that consumer accepts because being rich in the nutriment such as gamma aminobutyric acid and dietary fiber day by day, but mouthfeel is not good, and lysine and tryptophane relative deficiency, hot digestion operation are loaded down with trivial details have impact on further genralrlization and development.Potato full-powder almost remains whole nutritional labeling and the local flavor of fresh potato, and mouthfeel is good, comprehensive nutrition, amino acid reasonable mixture ratio, has day by day become food and the raw-food material of Chinese Consumer's favor.The present invention is directed to the following major defect of traditional sprouted unpolished rice, propose a kind of new instant food---sprouted unpolished rice facilitates mashed potatoes and production method thereof.
Summary of the invention
Main purpose of the present invention is to provide a kind of sprouted unpolished rice mashed potatoes and preparation method thereof, and the sprouted unpolished rice mashed potatoes obtained by the method can improve the eating mouth feel of brown rice, promotes nutritive value, without the need to boiling before edible, and instant edible.
The invention provides a kind of preparation method of sprouted unpolished rice mashed potatoes, comprise the following steps:
Brown rice germination is cultivated.Be not placed in constant-temperature constant-humidity environment with water logging after taking the brown rice cleaning of certain mass, design temperature is 20-35 DEG C, and humidity is 80-95%; Drained after 12-14h and be layered on moistening gauze, observed every 4-6h moisturizing of once spraying in time; About 3-4 days, brown rice germinates successively; Ozone sterilization is used to prevent microbial contamination in germination process.
Sprouted unpolished rice pre-gelatinized.Sprouted unpolished rice clean water is placed on 1-4h in the thermostat water bath of 40-70 DEG C, with 0.5-2h in the water at low temperature bath being placed on 10-30 DEG C, crosses and filter excessive water, then boiling 10-30min, cook that rear to put into rapidly the environment of less than-30 DEG C freezing.
The dehydration of pre-gelatinized sprouted unpolished rice.Pre-gelatinized sprouted unpolished rice is placed in freeze drying equipment, through 8-24h freeze drying, makes its water content be reduced to less than 4%, and form the cavernous structure being beneficial to rehydration.
Dehydration sprouted unpolished rice obtains sprouted unpolished rice mashed potatoes.To dewater sprouted unpolished rice, potato full-powder, soybean or peanut protein powder mixing, and pack or box after microwave disinfection, be product again.Comprehensive reference human body essential amino acid every day average requirement and brewed mouthfeel show that good compound proportion is: dehydration sprouted unpolished rice 10g, potato full-powder 23g, soybean or peanut protein powder 3g.Can suitably add other auxiliary material, as dehydration laver and salt etc., carry out the seasoning of different mouthfeel.
The present invention also provides a kind of sprouted unpolished rice mashed potatoes, comprises dehydration sprouted unpolished rice, potato full-powder and albumen powder.
Described sprouted unpolished rice mashed potatoes also can suitably add other auxiliary material, includes but not limited to dehydration laver, salt, dehydration egg flower or other dehydrated vegetables.
Described sprouted unpolished rice mashed potatoes comprises dehydration sprouted unpolished rice 10g, potato full-powder 23g, albumen powder 3g, dehydration laver 1g and salt 0.5g.
Described albumen powder is soyabean protein powder or peanut protein powder.
Beneficial effect of the present invention is: it is composite that sprouted unpolished rice and potato full-powder and soybean or corn protein powder are carried out science by the present invention, not only remain the feature that sprouted unpolished rice is rich in gamma aminobutyric acid, significantly improve the bad mouthfeel of brown rice, also achieve the balanced proportioning of nutrition, in such as potato full-powder, lysine relative abundance supplements the lysine relatively lacked in brown rice, and soybean or peanut protein powder supplement the tryptophan that brown rice lacks.Brown rice after germination through pre-gelatinized and processed, only needs, with hot-water soak, to reach the effect without the need to boiling, instant edible before edible by the present invention simultaneously.
Specific embodiment
Hereafter in detail embodiments of the invention will be described.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they mutually can be combined and be combined with each other thus reach better technique effect.
