The product uses high-quality fresh grass or green hay or forage plants of leaf vegetables and soybean as raw materials and the process flow includes the following steps: (1) producing paste of leaf protein capable of renaturating and soybean milk; (2) boiling soybean milk; (3) diluting leaf protein paste; (4) mixing soybean milk with leaf protein solution; (5) adding coagulant; (6) filling; (7) thermal coagulating and shaping. The color of the product varies from tiny green to light green, the quality is fine and smooth, the product is rich in chlorophyll, carotene and other vitamins, the nutrition value is better than common filling bean curd, and has a preservation character same with other filling bean curds. The invention provides important pathways for producing human daily food using a large amount of leaf protein, for producing leaf protein products with high-efficiency and low-energy consumption, for producing leaf protein foods with high water contents in large-scale, for producing leaf protein bean curd capable of transporting for long distances and preserving on shelf for long times.
Description
Affiliated technical field
The present invention relates to fresh herbage or green hay or leaf vegetable plant is main or important source material, is equipped with an amount of soybean, and takes the method for heating coagulation forming is produced after the liquid can a kind of bean curd appearance processed food and processing and fabricating method thereof.
Technical background
In the face of the population pressure that continues to increase and the raising of people's living standard; The exploitation protein resource; Need become countries in the world with what satisfy human lives, production, especially resemble nervous country faced the long-term and difficult task of the such per capita cultivated land of China.Plant leaf blade is considered to maximum and cheap a kind of renewable protein resource on the earth; Angle evaluation from amino acid balance; Leaf protein quality and soybean protein are similar; And leaf protein if can be developed as the human food effectively because of being rich in chlorophyll, carrotene, VE and other vitamin, will have the incomparable advantage of seed albumen.
The annual leaf protein of producing in the whole world is in the only tens thousand of tons of dry product at present, and with respect to its huge raw material resources and human demand to albumen, this production scale all is very limited even inappreciable.According to one's analysis, a large amount of reasons of development of restriction leaf protein production mainly are production cost problem and product purpose problem.Because the processing and utilization mode that extensively adopts in the world needs to carry out dried to condensing the high-moisture albumen that through heating or fermentation or other lixiviate coprecipitation mode in the leaf juice; Make that power consumption of polymer processing is too high (as adopting spray drying process, to be produced one kilogram of dry powder and consume 10 approximately and spend; As adopt novel low-temperature vacuum drying method, and power consumption is also between 2.5～3 degree/kg), proportion of products too small (account for forage fresh weight 2.5～3%); And product is mainly used in feeding purposes; Price is limited, makes its economic benefit humble, thereby has restricted the development of leaf protein extraction and application.
National inventing patent " vegetable protein marbling bean curd and processing and fabricating method thereof " be one be reduce to produce the energy consumption of leaf protein product, and be used for the important exploration that human daily bread is done to leaf protein in large quantities.But because the technical characterstic of this invention, it can only produce plate bean curd, and can not production can bean curd, thereby aspect guaranteeing the quality, has limitation, is not easy to scale ground centralized production.The product that the present invention is directed to leaf protein bean curd problem of guaranteeing the quality has proposed new processing technology, has solved the problem of utilizing leaf protein to produce filling type bean curd, for the large-scale production of leaf protein bean curd provides guarantee.
Summary of the invention
The object of the invention and meaning are:
1, providing a kind of is main with the plant leaf protein or important component, color and luster little green to light green, quality is fine and smooth, taste is salubrious, nutritious, be rich in chlorophyll and multivitamin filling type bean curd appearance product and processing and fabricating method thereof.
2, the present invention is on the basis of the energy-conservation of national inventing patent " vegetable protein marbling bean curd and processing and fabricating method thereof " and the thinking of expanding the leaf protein product purpose; Take new processing technology; Realized producing the target of filling type leaf protein bean curd, thereby important leverage is provided for the large-scale production of leaf protein bean curd.
Technical scheme of the present invention is:
1, raw material and proportioning:
Press natural air drying restatement amount, fresh leguminous forage or green hay or leaf vegetable plant: soybean=2～8: 1
Wherein said leguminous forage is alfalfa, Bai Sanye, red clover, big winged bean, sieve pause bright grass or the green hay of pure, the of fine quality nontoxic leguminous forage of beans, crowtoe, Chinese milk vetch, sainfoin and other smell, and the leaf vegetable plant refers to green vegetables, wide heart dish, pakchoi, spinach, Grain Production of Amaranthus, wild cabbage, leaf beet and pure, the of fine quality nontoxic leaf vegetable plant of other smell.When producing a product, can be simultaneously cooperate with soybean with multiple in the above-mentioned forage plant, also can use in the above-mentioned forage any one to cooperate with soybean.
Herbage that provides and the ratio of soybean adopt natural wind dry weight ratio; This is because bright careless water content has than big-difference because of differences such as kind, season, the places of production; As measuring with fresh weight; Then be unfavorable for controlling the ratio of leaf protein and soybean protein in the present invention's the product, thereby influence moulding, external appearance characteristic and the local flavor of product.Add man-hour as being raw material with bright forage actual, need at first go out the ratio of forage fresh weight and soybean according to the ratiometric conversion of careless cobalt blue pigment of aquatic foods and air-dry thing, prepare burden in gained herbage fresh weight and soybean ratio then.
2, processing and fabricating method:
(1) its main work flow is:
1. forage pull an oar → add alkali lixiviate protein → thick slag of mistake elimination → centrifugal go thin slag → add acid deposition → centrifugal and washing precipitation → the wet cream of leaf protein → add water furnishing pulpous state is for use
As use bright forage, the consideration from reducing discharging can economize the link of lixiviating lixiviate.
2. soybean defibrination → filter → boil → cool off → mix soya-bean milk and leaf protein → adding coagulating agent → can → heating coagulation forming → cooling
(2) its technology characteristics is:
Regulate pH to 8～10 when 1. the forage slurry adds alkali lixiviate protein, lixiviate 1～2h stirs with 20～30r/min speed therebetween;
2. the forage slurry is through the thick slag of 60～80 order eliminations, again through the thin slag of the centrifugal elimination of 200～300 orders;
Regulate pH to 3.5～5 when 3. adding acid deposition leaf protein, deposition 20～30min;
Make water content be controlled at 60%～65% when 4. adding water modulation leaf protein slurry;
5. soybean slurrying total water amount is 9～10: 1 with the ratio of dried soybean;
6. be cooled to after soya-bean milk boils below 30 ℃ and mix with the leaf protein slurry again;
7. the coagulating agent consumption is 0.2%～0.3% of leaf protein and a soya-bean milk mixed pulp;
8. the temperature that heats coagulation forming is controlled at 85～90 ℃, and setting time is 20～25 minutes;
