The production method comprises soilless culture of heavy-metal-free rice and processing of rice protein, wherein each liter of a soilless culture nutrient solution in the formula comprises the following components by weight: 0.6g-0.8g of potassium nitrate, 0.1g-0.3g of calcium nitrate, 0.6g-0.8g of magnesium sulfate, 0.4g-0.5g of ammonium phosphate, 0.2g-0.3g of potassium sulfate, 0.2g-0.3g of potassium dihydrogen phosphate, 15mg-30mg of ferrous sulfate, 6mg-10mg of boric acid, 4mg-6mg of manganese sulfate, 1mg-3mg of zinc sulfate, 0.2mg-0.3mg of copper sulfate and 0.4mg-0.6mg of ammonium molybdate; after soaking and grinding the rice, carrying out liquidation standardization, wherein the enzyme dose is 1%-2%, and the pH is 5.8-6.2; and carrying out jetting liquidation at 108 DEG C and dextrinization at 95-98 DEG C on materials, filtering, collecting rice residue with high protein concentration, inputting the rice residue into a slurry mixing tank, injecting hot water of 80-95 DEG C to blend into a protein fluid with the concentration of 10%-30%, carrying out colloid milling and dehydration, drying, and grinding. According to the production method, heavy metal pollution in soil is fundamentally avoided, a production process is simplified, the production cost is lowered, the work hour is shortened, meanwhile, the yield of protein is increased, and the taste and the flavor of protein are guaranteed.
Description
Technical field
The invention belongs to food processing field.
Background technology
The features such as it is reasonable that rice protein has amino acid Compositional balance, and biological value is high, and nutritive value is high, can compare favourably with egg, cow's milk, beef.In addition, rice protein is opposing original shape albumen, can not produce anaphylaxis, can be used for producing infant or baby food.The trophic function of the uniqueness had because of rice protein and nourishing function.In recent years, market is all the more fervent to the demand of rice protein.
Produce rice protein by the by product rice residue of producing β-amylose, not only can obtain the rice protein of high density, also can save production cost, be one of means of current domestic production rice protein.But no matter be use rice or rice residue to produce in rice protein process, due to the heavy metal of Raw Materials Rice in process of growth in easy Enriching soil, cause rice heavy metal content higher, so need in production technique to remove cadmium by acid (hydrochloric acid) method, avoid the serious problems of product heavy metals exceeding standard.But the acids that removing heavy metals is used, often makes amylolysis, make protein denaturation, thus affect local flavor and the mouthfeel of product.Further, after acid system removing heavy metals, material needed sheet frame to be separated with heavy metal by albumen further, and this can cause protein yield greatly to reduce, and increased production cost and man-hour.
Summary of the invention
The object of the present invention's invention overcomes the deficiencies in the prior art, proposes a kind of production method of heavy metal free rice protein.
The present invention is that scheme realizes by the following technical programs.
Production method of the present invention, comprises soilless culture and the rice protein processing of heavy metal free rice.
(1) soilless culture of heavy metal free rice.
The soilless culture of heavy metal free rice of the present invention, comprise the preparation of soilless culture nutrient fluid, the formula of soilless culture nutrient fluid is as follows: containing saltpetre 0.6 ~ 0.8 g, nitrocalcite 0.1 ~ 0.3g in often liter of soilless culture nutrient fluid, magnesium sulfate 0.6 ~ 0.8 g, ammonium phosphate 0.4 ~ 0.5 g; Potassium sulfate 0.2 ~ 0.3 g, potassium primary phosphate 0.2 ~ 0.3 g, ferrous sulfate 15 ~ 30 mg; Boric acid 6 ~ 10 mg, manganous sulfate 4 ~ 6 mg, zinc sulfate 1 ~ 3 mg, copper sulfate 0.2 ~ 0.3mg, ammonium molybdate 0.4 ~ 0.6 mg.
(2) working method of heavy metal free rice protein: the heavy metal free rice adopting the soilless culture of step (1) is raw material, with rice: water is that 1 ﹕ 1 ~ 1 ﹕ 2 proportioning soaks 1 ~ 2h.Crossed by material after 60 orders are pulverized and carry out liquefaction stdn, wherein enzyme concentration is 1% ~ 2%, pH5.8 ~ 6.2.Material after stdn is steam ejection liquefaction 3 ~ 5min at 108 DEG C.Dextrinization is carried out subsequently in 95 ~ 98 DEG C.By the material filtering after dextrinization, the byproduct high protein concentration rice residue of collecting gained directly inputs sizes mixing in tank, injects 80 ~ 95 DEG C of hot water, is deployed into the protein liquid that concentration is 10% ~ 30%.Protein liquid is dewatered after colloidal mill 2 ~ 3 fine grindings, dry at 90 DEG C ~ 160 DEG C.Be finally 100 ~ 300 orders by dried albumen Crushing of Ultrafine, carry out metal detection, packaging, gets product.
Soilless culture (soilless culture) refers to and does not use soil, and do seedling medium with light materials such as the peat composed of rotten mosses or forest leaf-humidified soil, vermiculites and fix plant, root system of plant is allowed directly to contact nutritive medium, adopt the modernization seeding raising technology of mechanize precision drilling once-seedling forming, comprise water planting, mist (gas) training, substrate culture.Select seedling dish to be lattice room, sow lattice one, seedling one Room one strain, root system and the matrix of seedling are intertwined mutually, the stopper shape that root sticks together big up and small down, generally make cave coil non-soil culture.
Soilless culture can manually be prepared because of nutrient solution used, growing environment artificial adjustment, and the root system of vegetables is complete and soil is isolated, effectively can stop soil-borne disease, the heavy metal ion that minimizing plant absorbs from soil and nitrite content.Meanwhile, the vegetables of soilless culture, owing to not contacting fertilizer and pesticide, no matter outward appearance and mouthfeel are all better than common vegetable.So soilless culture according to the different growth needs change nutritive mediums of plant, can not only reach the needs of cultivating optimum nutritional status, has also fundamentally completely cut off the absorption of plant heavy metal, solve the problem that plant heavy metal content exceeds standard.
The invention has the beneficial effects as follows: adopt soilless culture to cultivate rice, from rice vegetative period, just stopped the heavy metal contamination in soil.The later stage with soilless culture rice for raw material production rice protein time, can directly obtain heavy metal free polluted product, save albumen in traditional technology " acid system except cadmium " step, cost-saving, shorten man-hour.Meanwhile, can also avoid except cadmium hydrochloric acid is to the disadvantageous effect of albumen mouthfeel, local flavor etc.Compared with traditional technology, present method, owing to using soilless culture raw material, fundamentally can stop the heavy metal contamination of product, in simplification production technique, while reducing production cost, promote albumen yield, ensure albumen mouthfeel and local flavor, there are wide market outlook.
