Description

The processing method of buckwheat potato quality control of fried instant food
Technical field
The present invention relates to field of food, and in particular to a kind of processing method of buckwheat potato quality control of fried instant food.
Background technology
Buckwheat, scientific name hull buckwheat (Tartar, pronunciation d á d á, are the general designations to Chinese ancient northern ethnic group), alias Buckwheat leaf seven, wild blue buckwheat, Wan Nianqiao, spinach wheat, black wheat, Hua Qiao.It is higher by much than the nutritive value that sweet tea buckwheat is buckwheat.It is particularly biological The content of flavonoids is 13.5 times of buckwheat.Buckwheat -- seven major nutrient rolls into one completely, is not medicine, is not health products, is Can but there are the healthy nutritive value of brilliance and outstanding dietotherapy effect when the food that meal is eaten.It does not belong to grass family, and belongs to knotweed Section, polygonaceae is belonged to together with " fleece-flower root, rheum officinale " familiar to people etc., be typical case's embodiment of China's integration of drinking and medicinal herbs culture.Buckwheat quilt It is described as " kings of five cereals ", three drop food (hypotensive, hypoglycemic, reducing blood lipid).Nutrition unique, comprehensively, abundant that buckwheat possesses into Part, and medicinal characteristic is good, there is a variety of nutritions necessary to human body.Buckwheat has the effect of catharsis and toxin expelling, among the people to be also known as it For " net intestines grass ".Buckwheat can be to make tea-drinking after frying, drink has auxiliary therapeutic action daily to the three high patients.
Buckwheat originates from Southwestern China portion, and it is habitually attributed to Cereal, wheat class, Gui little Zong by people for grain with purpose Grain bean crop, actually buckwheat are the food sources for eating medicine dual-purpose.Chinese Scientists research is found:Buckwheat is strange in five cereals Flower, there are very high edibility and medical care effect, be a kind of functional food ingredient of great exploitation potential.Edible buckwheat is straight It is diuresis defaecation to see display effect.Detection data show that buckwheat has hypoglycemic, reducing blood lipid, urine glucose lowering, treats stomach disease and improve just The diet therapy nutritional function of secret " it is logical that three drops one treat two ".
The buckwheat that in the market is much sold makes buckwheat tea more, but buckwheat tea passes through expanding treatment, or powder mostly Reprocessed after broken, although appearance is preferable, the active ingredient of buckwheat can be destroyed.In addition, raw buckwheat needs to pass through suitably Can just do tea-drinking use after baking and banking up with earth processing, but buckwheat to bake and bank up with earth technological requirement higher, it is easy to fried the duration and degree of heating that is fried, or frying Less than destroying the effective ingredient of buckwheat, influence the leaching rate of mouthfeel and rutin.Protein, the fat of buckwheat are all higher than wheat Flour and rice, protein are higher than corn flour.Vitamin B2 is higher than wheat flour, rice, is 4~24 times of corn flour. Mineral nutrient element is also all higher than other grain kinds in various degree.Buckwheat also containing rice, face and other cereal without nutritional activities The factor:Buckwheat flavone:Containing aldehydes matters such as rutin, Quercetin, double-colored element, camphane phenanthrene alcohol, there is softening blood vessel, improve microcirculation, clearly Thermal detoxification, promoting blood circulation and removing blood stasis, hypoglycemic, glucose in urine, blood fat, strengthen insulin peripheral action.
Buckwheat sugar alcohol can degrade D-chiro-inositol in the presence of human body intestinal canal microorganism, improve the sensitiveness of insulin, So as to reduce the blood glucose of animal and human body, blood lipid level.The cis cinnamic acid of 2,4-dihydroxy:Black is generated containing skin is suppressed Plain material, senile plaque expelling and freckle can be prevented.Protein hinders enzyme:There is the proliferation function for hindering leukaemia.Anti- (slow) digestion Starch plays the role of to prevent blood glucose from rising and lose weight soon.850 Yi nationality's polls are tabled look-up bright, eating 100 grams of buckwheat wheat flour daily can Reduce cholesterol and low-density lipoprotein.62 Hans' patients with NIDDM drink 6 grams of buckwheat blood-sugar reducing teas per Tianchong, after 18 months Reduce on an empty stomach with postprandial blood sugar positive effect, it is effective to account for 90.32% with effectively total.Constipation patient and ordinary people's edible buckwheat tea 7-10 days, easily go to toilet.
Buckwheat is the natural function food for integrating " nutrition, health care, medical treatment ".On buckwheat wheat diseases prevention in China's ancient books The record cured the disease.《Qimin yaoshu》Have " intermittent headache fears cold person, using noodle soup and powder as cake, more makes net for catching birds or fish perspire, though many decades are also cured ". 《Figure is through book on Chinese herbal medicine》There is the record of " real stomach, benefiting energy ".《Herbal guiding principle wood》Have that " sending down abnormally ascending wide intestines mill is stagnant, the swollen wind pain of the heat that disappears, except white The discussion of turbid stasis, spleen product diarrhea ".It is bitter in taste, flat, cold to record buckwheat wheat, has benefiting energy, continue spiritual, sharp knowledge, the wide intestines of sending down abnormally ascending The effect of stomach invigorating.《The Illustrated Book on Plants》Claim buckwheat " performance disperse accumulations, custom exhale net intestines grass ".Buckwheat energy hypotensive, hypoglycemic, drop blood Fat, improve the effect such as microcirculation, also known as " three drops " food.
One investigation of Public Health College, Harbin Medical Univ shows, the crowd in staple food buckwheat area, its blood sugar level With crowd of the diabetes prevalence significantly lower than not edible buckwheat area.Wherein, resident's elevated blood glucose levels of staple food buckwheat are (i.e. high In the blood sugar level of normal value) recall rate be 1.6%;Rather than the crowd of staple food buckwheat, the recall rate of hyperglycaemia is 7.33%, The latter is higher than the former nearly 4 times.The regional diabetes prevalence of staple food buckwheat and not edible buckwheat also differs about 1 times, Qian Zhewei 1.88%, the latter 3.84%.This conclusion is prompted, and buckwheat is as the effectively reduction pathogenetic rain fed crops of glycosuria, it should more On the dining table for appearing in common people more.
Zoopery shows that buckwheat flavone can make the triglyceride levels of hyperlipidemic mice and the courage of hyperlipemia rat Sterol and triglyceride levels substantially reduce;But it does not reduce the hdl level of the two, therefore buckwheat flavone With effect for reducing blood fat.Raw buckwheat needs just do tea-drinking use after appropriate baking and banking up with earth is processed in addition, but the baking of buckwheat It is higher to train technological requirement, it is easy to fried it is fried, or the duration and degree of heating fried less than, destroy the effective ingredient of buckwheat, influence mouthfeel with And the leaching rate of rutin.Because Quercetin being rich in buckwheat bioflavonoid etc. can reduce triglycerides and total courage is consolidated Alcohol content, reduce atherosclerosis index.
The bioflavonoid main component being rich in buckwheat is rutin, also known as VP, its primary efficacy are softening blood vessels, are improved Microcirculation, clearing heat and detoxicating, promoting blood circulation and removing blood stasis, removing toxic substances and promoting tissue regeneration, QI invigorating are refreshed oneself, and play the role of hypoglycemic and glucose in urine.Dutch Michele The male doctors of He Tuoge are determined to the content of bioflavonoid in 805 elderly men meals, as a result find, daily intake The amount of bioflavonoid is not less than 30mg group, and 19mg group is not more than than daily intaking bioflavonoid amount, dies from coronary heart disease Danger reduce 50%.Magnesium has well-tuned effect to cardiac activity, can make cardiac rhythm and heart conduction of putting forth energy slows down, increase Myocardial blood supply amount, favourable diastole and rest.Content of magnesium in buckwheat wheat is more than 11 times of wheat flour.
There is buckwheat bioflavonoid many physiological functions, Quercetin and morin therein etc. can improve body The contraction of vascular smooth muscle and diastolic function;Rutin has the function that to expand blood vessel, can maintain the resistance of capillary, reduce Its permeability and fragility, promote hyperplasia and prevent the aggegation of haemocyte, also reducing blood lipid, coronary artery dilator, enhancing hat Shape blood flow volume etc. acts on.Contained abundant vitamin plays the role of to reduce human body blood fat and cholesterol in buckwheat, is to control Treat important auxiliary food (medicine) thing of hypertension and cardiovascular disease.Some micro- (such as magnesium, iron, copper, the potassium contained in buckwheat Deng) there is protective effect for angiocarpy.
Research confirms that Quercetin that buckwheat bioflavonoid is rich in, morin, kaempferol have antibacterial and antiviral work With.The clinical practice flavones, there is the peculiar curative effect of putrefaction-removing granulation-promoting, anti-inflammatory analgesic to ulcer caused by a variety of causes.
Free radical (free radical) be cause cancer, aging, cardiovascular and cerebrovascular degenerative disorders crime source.Because Buckwheat flavone material is easily oxidized, and just makes it have the function of removing free radical.The molecule knot of buckwheat bioflavonoid composition Structure meets effective phenolic hydroxyl group theory, has extremely strong radical scavenging activity, they have 5 hydroxyls, can sufficiently conduct Hydrogen donor, make radical reduction, so as to play a part of removing free radical, reach health care, anticancer, the mesh of resisting cardiovascular disease 's.Liver protection effect buckwheat bioflavonoid is to acute, chronic hepatitis, hepatic sclerosis, fatty liver, and because galactosamine and CCl4 etc. draw The toxic liver injury risen has the effect of certain.Research shows that buckwheat bioflavonoid is to liver MDA caused by CCl4 (MDA liver lipid peroxidations end-product) increasing for content has obvious inhibitory action;Hepatic injury can be mitigated to glutathione (GSH) Consumption;Cyto-architectural integrality can be protected, prevents the lyoenzymes such as the transaminase in liver cell because being spilt from cell And activity rise.The protect liver mechanism of buckwheat bioflavonoid is finally the effect of its anti-oxidant and Green Tea Extract.
Potato, belonging to Solanaceae herbaceos perennial, stem tuber can be edible, is the third-largest important cereal crops in the whole world, It is only second to wheat and corn.Potato is also known as potato, potato, foreign sweet potato etc., the stem tuber of plant of Solanaceae.With wheat, corn, rice Paddy, sorghum simultaneously turn into five big crop of the world.
Ingredient in general fresh potato:Starch 9~20%, protein 1.5~2.3%, fat 0.1~1.1%, Crude fibre 0.6~0.8%.Contained nutritional ingredient in 100g potatos:The kilojoule of energy 318,5~8mg of calcium, 15~40mg of phosphorus, Iron 0.4mg~0.8mg, 200~340mg of potassium, iodine 0.8~1.2,12~30mg of carrotene, 0.03~0.08mg of thiamine, core 0.01~0.04mg of flavine, 0.4~1.1mg of niacin.
Potato tubers contains substantial amounts of starch.Starch is the main energy sources of food potato.General early seasonal strain horse Bell potato contains 11%~14% starch, and mid-late mature seed contains 14%~20% starch, and the stem tuber of high starch varieties is reachable More than 25%.Stem tuber is also containing glucose, fructose and sucrose etc..Potato protein nutritive value is high, and potato tubers contains 2% or so protein, protein content is 8%~9% during potato is dry.It was found that the protein nutritive value of potato is very high, Its quality is equivalent to the protein of egg, easily digestion, absorption, better than the protein of other crops.And the albumen of potato Matter contains 18 kinds of amino acid, including the various essential amino acids that human body can not synthesize.The nutritive value of potato is spoken highly of, is With its stem tuber contain the lysine of high-grade protein and essential amino acid, tryptophan, histidine, arginine, phenylalanine, The presence of valine, leucine, isoleucine and methionine is undivided.Potato tubers contains multivitamin and inorganic Salt.The effect that food potato is good for one's health with vitamin is undivided.Particularly vitamin C can prevent scurvy, thorn Swash hematopoietic function etc., be no in the daily rice eaten, fine flour, and potato can provide substantial amounts of vitamin c.In stem tuber Also containing vitamin A (carrotene), vitamin B1, (thiamine), vitamin B2 (riboflavin), pellagra preventive factor (nicotinic acid), dimension life Plain E (tocopherol), vitamin B3 (pantothenic acid), vitamin B6 (pyridoxol), vitamine M (folic acid) and biotin H etc., are good for human body Health is all beneficial.In addition, inorganic salts such as calcium, phosphorus, iron, potassium, sodium, zinc, manganese etc. in stem tuber, and the health to people and child The indispensable element of growing.Containing abundant dietary fiber in potato tubers, and containing abundant sylvite, belong to alkali Property food.There is data expression, its content and apple are as many.Therefore absorption of the stomach and intestine to potato is slower, after food potato, The time rested in enteron aisle much longer than rice, so having more satiety, while can also help to take away some greases and rubbish Rubbish, there is certain catharsis and toxin expelling to act on.In addition, the stem tuber of potato also contains unexistent Hu trailing plants in cereal grain Bu Su and ascorbic acid.From the point of view of nutritional point, it has the advantages of more than rice, flour, and it is largely hot to supply human body Can, it can be described as " food perfect in every way ".People is enough to sustain life if only leaning on potato and whole milk and health.Because The nutritional ingredient of potato is very comprehensive, and also relatively rationally, simply the amount of protein, calcium and vitamin A is slightly lower for trophic structure;And this Just supplemented with whole milk.Potato tubers washiness, lean, unit volume heat are at a fairly low, the life of contained dimension Plain C is 4 times of apple or so, and B family vitamin is 4 times of apple, and various mineral matters are several times to tens times of apple, horse Bell potato is hypotensive food, and certain nutrition is more in meals or has lacked and can cause a disease.As a same reason, meals are adjusted, also can " eating " falls corresponding disease.Potato has the effect of anti-aging, and it contains the B races such as abundant vitamin B1, B2, B6 and pantothenic acid dimension Raw element and substantial amounts of good fiber quality element, also containing nutrients such as trace element, amino acid, protein, fat and high-quality starch. Potato is carbohydrate, but its content is only 1/4 or so of equivalent weight rice, and research shows, the shallow lake in potato Powder is a kind of resistant starch, has the function that to reduce adipocyte.Potato is extraordinary hyperkalemia hyponatremia food, is well suited for water Swollen type overweight people eats, and is enriched plus its potassium content, almost highest in vegetables, so also having the effect of thin leg.Thus Understand, potato has very high nutritive value and medical value, and therefore, potato is fabricated to various productions extensively Product.
Potato full-powder is one kind in dehydrated potato products, cleaned, remove the peel, choose using fresh potato as raw material Select, cut into slices, rinsing, precooking, cooling down, boiling, smashing the technical process such as mud, through fine particulate, piece obtained by dehydrating consider to be worth doing shape or Powdery product system is referred to as potato full-powder, and potato full-powder has cured in process, and therefore, potato full-powder has Very strong glutinous viscosity, still, its corresponding ductility are poor, and a kind of Flour product is formed after potato full-powder is mixed with flour Base-material, if the content of potato full-powder is more than 25% in the base-material, it is difficult to maintain flour original when making and curing Flour product Processing characteristics, for example, poor in the quality control of fried instant food bulkiness being fabricated to using the base-material, to the mouth of quality control of fried instant food Sense has a great impact.
Farina is with fresh potato, cleans, crushes by raw material, filtering, being dehydrated, drying, the work such as subpackage Sequence processing forms, have the characteristics that it is pure white it is sparkling and crystal-clear, quality is fine and smooth, viscosity is high, therefore, farina has extension well Property, still, the glutinous viscosity of corresponding farina is poor, is not easy agglomerating, formation one after farina is mixed with flour Kind Flour product base-material, if the content of farina is more than 25% in the base-material, it is difficult to tie up when making and curing Flour product The original processing characteristics of flour are held, for example, during quality control of fried instant food is made using the base-material, quality control of fried instant food is difficult With shaping, it is difficult to process.
Fried food is one of traditional food in China, fried fried dough twist either on New Year's Day or other festivals, fried spring roll, Deep-fried meatballs, is gone back It is deep-fried twisted dough sticks, oil cake, the face nest that daily breakfast is eaten;Children like chips, fried bread and zero in edible foreign fast food Chrips, fried biscuit in food etc., none is not fried food.Fried food can be promoted because of its palatable crisp, with fragrance striking the nose Appetite, so deep liked by many adults and children.
Potato quality control of fried instant food refers to, using flour as primary raw material, a certain amount of potato full-powder be added in flour Or farina, by sorting → dispensing → mixing → stirring → shaping → boiling → frying → cooling → packaging → finished product, At present, the processing method on potato quality control of fried instant food has a lot, the processing side of existing potato quality control of fried instant food Method is processed after directly potato full-powder is directly individually mixed with flour, due to the characteristic of potato full-powder, The potato full-powder content added in flour is no more than 25%;Or individually mix farina with flour, due to horse The characteristic of bell sweet potato starch, the farina content added in flour are no more than 25%:Thus, utilize existing potato Potato content is not high in potato quality control of fried instant food made of the processing method of quality control of fried instant food, moreover, potato The content of the potato contained in quality control of fried instant food is higher, is more difficult to maintain the original processing characteristics of flour in processing, its Processing characteristics are poor, cause that the production efficiency of potato quality control of fried instant food is relatively low, and product qualification rate is relatively low.
