Background technology
Corn is also claimed maize, maize, maize, grass family, annual herb.Corn is one of most widespread cereal crops in the world, and cultivated area is only second to wheat and paddy rice and occupies the 3rd.Planting range from 58 ° of north latitude (Canada and Russia) to 40 ° in south latitude (South America).
The corn sweet property of distinguishing the flavor of is flat, and have in the accent and whet the appetite, the peaceful heart of beneficial lung, clearing away damp-heat, sharp liver and gall, function such as delay senility.Vitamin content in the corn is very high, is rice, wheat 5-10 times.106 kilocalories of per 100 gram corn heat content, cellulose 2.9 grams, protein 4.0 grams, fat 1.2 grams, carbohydrate 22.8 grams, corn also contains special nutritional labeling, has special trophism.The content of its fat of corn, P elements, vitamin B2 occupies first of the cereal; Contain abundant linoleic acid and vitamin E in the corn, the cholesterol in human body level is reduced, thereby reduce arteriosclerotic generation; Calcic in the corn, irony are more, can prevent hypertension, coronary heart disease; Abundant glutathione is arranged in the corn, and this is a kind of anticancer factor, in human body, can combine with multiple external chemical carcinogen, makes it lose toxicity, excretes through alimentary canal then.Contain a large amount of lysine in the corn, can suppress tumor growth; Corn also contains trace elements of selenium, and selenium can quicken the human body inner oxide and decompose, and suppresses malignant tumour; Corn contains rich dietary fiber, can promote enterocinesia, shortens food through the gastral time, reduces the stimulation to colon of absorption and the carcinogen of noxious material, thereby can reduce the generation of colon cancer; Corn contains abundant carrotene, can be converted into vitamin A after being absorbed by the body, and has protective effect on cancer risk; It is aging that the luteole that corn contains can delay eyes.
China is the maize gold ribbon, and corn is one of China staple crops, and output occupies the second place of the world, is China's important food, feed and industrial chemicals.Grain and industrial corn are arranged, stick waxy corn, corn etc. by its starch composition and mouthfeel characteristic.
Contain more crude fibre in the corn, doubly than polished rice, the high 4-10 of smart face.Protein content is on the low side in the corn, and quality is not good enough, amino acid imbalance, lysine, tryptophan and methionine contain quantity not sufficient, be mainly and be difficult for the alcohol soluble protein that absorbed by human consumption.The corn starch pasting temperature is high, easy to be aging, and mouthfeel is thick and stiff, palatability is relatively poor.Not only the mouthfeel change is bad behind the age of starch, and digestibility and nutritive value reduce greatly simultaneously.Therefore, corn is mainly used in animal feeding-stuff and commercial production raw material.The corn that China is used for grain ration and food industry at present accounts for about 5% of corn total output greatly, about 2,500,000 tons of year consumption corns.The unbalanced grain security policy with country of corn consumption is runed counter to, and should adopt advanced method to improve the food flavor of corn, brings into play its natural food attribute, guarantees the supply of high-quality grain ration and food.
Summary of the invention
The present invention provides a kind of production method of corn pinenut pyramid-shaped dumpling, changes the present situation that present corn is used for feed, industrial chemicals in a large number, improves the ageing resistance of product; Make goods be easy to digest and assimilate; Nutritive value improves, and a kind of delicious good to eat corn staple food product is provided, the special alimentary health-care function of performance corn; Improve the edibility of corn, create bigger economic benefit and social benefit.
The technical scheme that the present invention takes comprises the following steps:
(1) the softening and anti-aging processing of corn
Fresh kernel corn is cleaned, and removes not edible impurity such as corncob, sand, stone, grass-seed, presses material-water ratio 1: 2-5 and adds boiling water digestion 10 min-30min; Be cooled to 75 ℃-85 ℃; 0.2%-0.5% by the iblet quality adds anti-70 ℃ of-90 ℃ of AMSs, is incubated 30 min-60min, and insulation is heated to 95 ℃-100 ℃ after finishing; Keep 10 min-20min, enzyme goes out;
(2) the pinenut flavouring is handled
Select that fresh nothing is gone mouldy, free from insect pests, nothing are become sour, the high-quality pinenut of edible impurity invariably; Washes clean flows; Get 20-50 part in per 100 parts of pinenuts and place baking box, adopt 150 ℃-180 ℃ to be baked to golden yellow, strong ripe pinenut fragrance is arranged after, be cooled to normal temperature; The living pinenut of shortening mixes with remaining not, and is subsequent use;
(3) the softening processing of glutinous rice
Inedible parts such as sand, stone, grass-seed are removed in the glutinous rice screening, after elutriation is clean, use 0.02%-0.5% Na
2CO
3Aqueous solution soaking 8-48h slowly cleans 2-3 time with clear water when the grain of rice soaks into no dried core fully, removes alkali lye;
(4) preparation of pinenut and corn pyramid-shaped dumpling filling material
The iblet of the pinenut of handling well and softening and anti-aging processing is by mass ratio 1: 5-20 mixes, and adds the soft white sugar of the 20%-40% of its gross mass, continues to stir, and sugar is dissolved and each material is uniformly dispersed, and is corn pinenut pyramid-shaped dumpling filling material;
(5) processing of rice-pudding leaf
To soft, the clear water washing removes crude removal, is soaked in the clean drinking water ready access upon use with the dry reed leaf cold water soak;
(6) pyramid-shaped dumpling packs and shortening
Pinenut and corn pyramid-shaped dumpling filling material and glutinous rice mass ratio are 1: 1-20, and need to adopt single leaf or double leaf to pack pyramid-shaped dumpling by production, boil or cook to the grain of rice soft and not mashed, glutinous glutinous good to eat.Notice that the filling material occupy the centre, the run-down loss that causes nutritional labeling and local flavor when preventing the pyramid-shaped dumpling boiling as far as possible.
The bright corn of the present invention is common bright corn, glutinous waxy corn or corn.
The present invention adopts special softening and anti-aging processing method; Give the good mouthfeel of corn of high fiber, high starch; Improved its local flavor; Pollution-free, no generation of waste materials, easy to operate has been widened corn range of application in food processing, and a kind of staple food food nutritious, instant is provided.
Softening and the anti-aging technology of the corn that the present invention adopts, mild condition, technology is easy, handling safety, raw material availability is high.
The product that the present invention obtains gets final product aquatic foods steaming, the usefulness of cooking, and also can carry out the quick-frozen processing and get into cold chain storage and sale.
