Description

A kind of rice made products using Rhizoma Dioscoreae modification and preparation method thereof
Technical field
The invention belongs to food technology field, be specifically related to a kind of rice made products using Rhizoma Dioscoreae modification and preparation method thereof, Major product is rice flour and new year cake, belongs to food technology field.
Background technology
One, rice noodle and bait block and new year cake rice flour
Rice noodle, also referred to as rice flour, meter Si or rice and flour, be a kind of rice-made food of liking of south China people, and Gu has " north noodles, south Side rice noodle " edible tradition, the most fashionable whole world.
Among ancient cookbook " food ", note rice noodle is " bright ".Traditional rice noodle is with rice as primary raw material, after soaking Rice grinds, water mixing is mixed thoroughly, cooks into cake block;Take advantage of heat that cake block utensil is squeezed into lines, cook under fresh and alive state.Five Say " powder rice steams bits " in Dai Xukai " origin of Chinese character system biography ", i.e. rice is broken into pieces.
Bait block, it is simply that the punching of the above-mentioned cake block cooked smash, kneading becomes variously-shaped, such as block, silk, sheet, can steam that can boil can Fry, be a kind of rice-made foods of liking of southwest people.People from Jiangsu and Zhejiang Provinces custom is " new year cake "." anxious with regard to a piece " has that " cakes wheat meal is sweet Bean thick soup ", Yan Shigu's explanations one: " rice and flour steaming of urinating then for bait ".Homecraft makes, and the most only need to be steamed by rice and parboil, Just can be smash by punching, kneading forms bait block.
The tradition taste of rice noodle bait block, nutritive value are the most single, it is necessary to be further improved.
It is noted that the area based on wheaten food, traditional consciousness thinks that rice does not has steamed bread, pancake, noodles to disappear well Changing, the most just lacked the selection of a kind of meals, rice noodle bait block has been considered as then the rice made products of digestion, this rice noodle the most in recent years Bait block is in fashion a major reason in the north.And having added the rice noodle bait block of Rhizoma Dioscoreae, the approval of " nourishing the stomach " will be the most universal.
Two, the change of rice noodle bait block
Rice noodle of generally living makes two methods: one, makes, be commonly called as " Calyx seu fructus physalis rice noodle ", its complex process after taking the fermentation of rice water mill, Produce time-consuming, be difficult to preserve.Its two, directly extrude in the machine after taking rice pulverizing, temperature frictionally makes its gelatinizing molding, It is referred to as " dry pulp rice noodle ".
Owing to form is different with feature, and regional difference, people be accustomed to distinguishing rice noodle be " Calyx seu fructus physalis rice noodle ", " acid powder ", " dry pulp rice noodle ", " rice flour ", " dried rice noodle ";It is generally acknowledged that in the industry " dry pulp rice noodle " and " rice flour " are the same thing;Special one carries It is that first four kinds refer generally to fresh and alive rice noodle (being also water rice noodle), and latter refers to the dry pulp rice noodle dried.
Now system live rice noodle have well-done rapidly, steaming and decocting fry that the most suitable, tasty uniformly resistant to cook is the most rotten, tasty and refreshing cunning is tender, boils rear soup The most turbid, it is easy to the feature of digestion, it is particularly suitable for leisure fast food and eats.
" dry pulp rice noodle " can cook before again cooking water send out, be convenient for carrying storage;Though so chewy is good, tasty insufficient, mouth Feel the best.
The change of bait block is mainly reflected in the introducing of machine power, and traditional " treadle-operated tilt hammer for hulling rice is pounded " kneading mode almost disappeares, take and Instead of be to utilize machine kneading, raw material also becomes " steaming powder " from " rice ".
In view of the nutrition of rice bait block is single, people start the coarse grain such as Semen Maydis, Sorghum vulgare Pers., Semen Fagopyri Esculenti are also taked bait block in recent years Production method makes semi-finished product food materials, is named to " corn bait " " sorghum bait " etc..
Contemporary rice noodle, due to the intervention of mechanized production, the innovation of materials, occurs in that many is broken up especially:
One of differentiation: live rice noodle and two points of world of rice flour of living.From mouthfeel, rice noodle of living mostly is " bright and beautiful muscles and bones ", and rice flour of living is many For " mellow muscles and bones ", rice noodle entrance of living is the most smooth, and rice flour entrance of living more glues glutinous.Particularly " Calyx seu fructus physalis rice noodle " and " acid powder " Distinguish the hugest: acid powder entrance " continuous easyization of acid ", Calyx seu fructus physalis rice noodle entrance " acid embrittlement somersault ".The root of this difference essentially consists in The employing that rice " hangs sizing process ".
The two of differentiation: dried rice noodle and half dried rice noodle are caught up from behind." dried rice noodle " is similar with " dry rice flour ", after drying not only Can preserve for a long time, and be not easy to go bad.Dried rice noodle is simple owing to making, and replaces Calyx seu fructus physalis rice noodle the most step by step.And half-dried rice Line has reduction effect good, and water sends out time short feature, has begun at supermarket semi-finished product cabinet mass selling.
The three of differentiation: existing system rice noodle alive is saved up strength to start out.In view of the storage of Calyx seu fructus physalis rice noodle is transported extremely inconvenient, and the shelf-life is non- The shortest;Generally, Calyx seu fructus physalis rice noodle contained by bamboo basket among the people, covers with wet towel simultaneously, can pass through bamboo basket at this and " ventilate ", And in the environment of down discharging micro-moisture " moisturizing " with wet towel, Calyx seu fructus physalis rice noodle can preserve 18~24 hours;When exceeding Between then break broken substantially, or stiff being difficult to is swallowed.Additionally, too many illegal retailer is in order to seek exorbitant profit, with rice inferior add Alumen, The additive that " sodium formaldehyde sulfoxylate " etc. are harmful to health is moulding, makes consumer be difficult to distinguish.Based on both, commodity section is now making rice noodle alive Become trend.
The four of differentiation: diversification of feedstock.In view of the popular acceptance of rice noodle is the highest, use for reference the way of " dry pulp rice noodle ", closely Over Nian, people start also to take rice noodle production method to make semi-finished product food materials, even add the coarse grain such as Semen Maydis, Sorghum vulgare Pers., Semen Fagopyri Esculenti Fruit and vegerable, now make existing food or take-away in dining room.
Three, the nutritional labeling of rice noodle bait block
People are using rice as usual staple food, and amount is big, are to supplement energy and the basal diet of nutrient.Refined rice master To be made up of starch, protein, lipid, vitamin, mineral and cellulose.
Rice noodle and the nutritional labeling of bait block and rice are basically identical, and rice every hectogram leading indicator is about: energy 355,000 Card, 7.4 grams of protein, 0.1 gram of fat, carbohydrate 81.5 grams, dietary fiber 0.3 gram, thiamine 0.02 milligram, riboflavin 0.02 milligram, 0.6 milligram of nicotinic acid, calcium 6 milligrams, 62 milligrams of phosphorus, 14 milligrams of potassium, 16.3 milligrams of sodium, 16 milligrams of magnesium, ferrum 3.2 milligrams, 0.8 milligram of zinc, selenium 7.48 microgram, copper 0.3 milligram, 0.6 milligram of manganese.
Starch and protein are the main components of rice, and wherein content of starch reaches about 80%, and protein accounts for about 8%.Rice Medicated porridge has stomach function regulating, spleen reinforcing, lung heat clearing effect.Rice water has yin nourishing, QI invigorating, the function moisturized, and nature and flavor are sweet flat, with rice water rush milk powder or to It is all more satisfactory that baby makees to assist diet.In the daily life of modern, the chance having rice water and congee is little, adds Select polished rice for pursuing mouthfeel, cause the nutrient of rice to be lost too much.Rice noodle and bait block technique, the most preferably remain this A little nutritional labelings.
While it is true, compare with coarse grain such as Semen Maydiss, the nutritional labeling of rice is the most single, particularly in rice " alcohol soluble protein " and " lysine " content is the most on the low side, adds some coarse grain, again not a slip of tongue sense in rice, becomes a kind of reason Want to select.
Four, nutrition and the theory of absorption
Absorb (absorption) this concept be commonly used in medical science, physics, in biology, and produce, excretion the meaning Relatively.
The mankind are unicellular organism and higher mammal, and the absorption process of nutrient is all that material molecule passes cell membrane entrance Intracellular, or left cell by the intracellular cell membrane through opposite side again, enter tissue fluid or blood.Entered through 10000000 year Changing, the narrow spectrum special mechanism of absorption of different material is occupied more importantly position by the mankind.
Nutrient substance in food in addition to vitamin, water and inorganic salt can directly be absorbed, protein, fat and The materials such as saccharide all directly can not be absorbed by body, need to be broken down into the small-molecule substance of simple in construction in digestive tract, Just can be absorbed and used.Food is broken down into simple in construction in digestive tube, can the process of absorbed small-molecule substance just claim For " digestion ".
In digestion process, include physics and food is decomposed by chemical mode: except chewing, enterogastric peristalsis grinds Mill, also includes, by the various Digestive systems secreted by digestive gland, complicated various nutrient substance are decomposed into the letter that intestinal wall can absorb Single compound, if carbohydrate breakdown is monosaccharide, breaks down proteins is aminoacid, and lipidolysis is glycerol and fatty acid.Then this Nutrient substance after a little decomposition is absorbed into internal by small intestinal (mainly jejunum), and then enters blood and lymph fluid.
No matter it is mechanicalness digestion or chemical digestion, the most all depends on the spleen and stomach function of health.Namely Saying, if food itself is relatively beneficial to invigorating the spleen and regulating the stomach, then contributing to the equilibrium of human nutrition structure, rice food adds Rhizoma Dioscoreae, It it is a good option.
Five, nutritive yam is worth
Rhizoma Dioscoreae is one of material of using as new resource for food of health ministry approval, is also the integration of edible and medicinal herbs authorized of Ministry of Public Health One of kind, be to use as vegetable or coarse grain by traditional habit.
China eats the Rhizoma Dioscoreae history of existing thousand of years, has " Rhizoma Dioscoreae sweet in the mouth, property described in the Shennong's Herbal of Han dynasty Flat, main support, qi-restoratives is won, except cold and heat pathogen, invigorating the spleen and replenishing QI power, long muscle, take normal hearing and eyesight for a long time ", rise at that time Rhizoma Dioscoreae the most by As good nutritious tonifying Chinese herbal medicine.
Traditional medicine is thought, Rhizoma Dioscoreae has the functions such as spleen invigorating, the kidney invigorating, benefit essence, to animal and people's weakness of the spleen and stomach, inappetence, Diabetes, constipation etc. have certain curative effect.Wherein, more preferably, the effect to lungs kidney is more for effect of fresh Rhizoma dioscoreae YIN nourishing;Dry The effect of Rhizoma Dioscoreae spleen reinforcing is strong;Rhizoma Dioscoreae is partial to kidney-tonifying sperm-generating, the moon of lung benefiting kidney;Stir-baked RHIZOMA DIOSCOREAE with soil is partial to tonifying spleen and stopping diarrhea;Parched with bran Rhizoma Dioscoreae is partial to strengthening the spleen stomach function regulating, supplementing the kidney to control the nocturnal.
Modern medicine measures, and Rhizoma Dioscoreae is starch-containing, polysaccharide, polyphenol oxidase, cholesterol, ergosterol, cupreol, manna The compositions such as polysaccharide, allantoin, dopamine, Rhizoma Dioscoreae alkali, phytic acid, also rich in multiple inorganic units such as several amino acids and iodine, phosphorus, calcium Element.Comparing other starch foods, polysaccharide and allantoin activity in Rhizoma Dioscoreae are higher.
Polysaccharide (polysaccharide) is to be formed by the condensation dehydration of multiple monosaccharide molecule, be molecule structure complicated and Huge glucide.All carbohydrates meeting macromolecular compound concept and derivant thereof are referred to as polysaccharide.In Rhizoma Dioscoreae Rich in unartificial yeast glucosan, be the one of polysaccharide, immunomodulating, radioprotective, regulation the intestines and stomach, help organizational structure regeneration Or repair, promote that wound healing and the prevention aspect such as cardiovascular and cerebrovascular vessel and diabetes are respectively provided with outstanding behaviours, to hepatitis, tumor, the heart Blood vessel, diabetes, blood fat reducing, anti-ageing aspect of waiting for a long time all have unique biological activity.
The lifes such as in Rhizoma Dioscoreae, the highest allantoin of activity has promotion cell growth, accelerates wound healing, horny layer softening albumen Reason function, is good consolidant and the antiulcer agents of skin trauma.Can be used as alleviating and treatment xeroderma, scaling skin Skin disease, skin ulcer, digestive tract ulcer and inflammation, all have good therapeutic effect to osteomyelitis, diabetes, liver cirrhosis, acne.Until 2009, the new technique extracting and using natural allantoin just started by legend group of Switzerland legend skin protection institute.
Machining experiment is it is also shown that compared with the Rhizoma Dioscoreae do not cut, cutting can cause Rhizoma Dioscoreae catalase, peroxidase And the rising of the antioxidation related enzyme activity such as polyphenol oxidase, but cause Vc, total phenols, flavonoid, reduced glutathion etc. The decline of Antioxidants, and its antioxidation relevant enzyme of whole non-divided Rhizoma Dioscoreae and antioxidant are kept at stable Level.
After measured, one kilogram of Rhizoma Dioscoreae powder is generally containing 112 grams of protein, total sugar 6.2 grams, reducing sugar 4.7 grams, fat 133.6 Gram, starch 287.3 grams, carotene 13.27 grams, P1261.84 milligram, K718.26 milligram, Na80.11 milligram, Ca54.17 Milligram, Fe678.26 milligram, Mn115.14 milligram, Zn204.62 milligram.Compare with fresh Rhizoma dioscoreae, total sugar, reducing sugar, carotene Substantially content reduces.
Modern nutriology also confirms that, Rhizoma Dioscoreae contains abundant starch, vitamin and phosphorus, calcium, magnesium, ferrum, zinc, copper, potassium etc. Mineral element, is all-ages nutriment.Meanwhile, in food aminoacid composition determine protein quality, and Rhizoma Dioscoreae must Although needing amino acid content slightly below Chicken Albumin standard, but apparently higher than WHO/ FAO standards of grading, this can making up with corn The deficiency of lysine during particularly rice is main meals person's food, improves people's utilization rate to protein.
Six, Rhizoma Dioscoreae biological nature
According to morphological characteristic, Chinese yam idioplasm resource is divided into 4 big kinds by gardening: long Rhizoma Dioscoreae (Dioscorea Polystachya), Dioscarea persimilis Prain et Burkill. (Dioscorea persimilis), mountain potato (Dioscorea fordii) and ginseng potato (Dioscorea alata).The Rhizoma Dioscoreae of this 4 type differs greatly in leaf portion and underground tuber's characters, it is easy to distinguish.
Use as vegetable, or medicine-food two-purpose, generally select long Rhizoma Dioscoreae, formal name used at school: Dioscorea polystachya, have another name called Rhizoma dioscoreae (Dioscorea polystachya Turcz.), Rhizoma Dioscoreae, Chinese yam, field potato, Buddhist palm potato etc., be a master of Rhizoma Dioscoreae Wanting category, plant classification is: plant kingdom, Angiospermae, Monocotyledonae, Dioscoreales, Dioscoreaceae (Dioscoreaceae), Wild yam (Dioscorea).
Long Rhizoma Dioscoreae is also commonly called as Rhizoma Dioscoreae, and Rhizoma Dioscoreae is, Dioscorea opposita, perennial winding liana, underground is cylinder Shape meat tuber, typical diameters 2-10cm, long 50-150cm, quality 300-3000g.
Long Rhizoma Dioscoreae be distributed widely in (height above sea level 150-850 rice) on the south China northeast, Hebei, Shandong, Henan, Huaihe River, Anhui, Jiangsu, Zhejiang (height above sea level 450-1000 rice), Jiangxi, Fujian, Taiwan, Hubei, Hunan, In Northern Guangxi, Guizhou, Eastern Yunnan the north (height above sea level 1500-2500 rice), Sichuan (height above sea level 700-500 rice), In Eastern Gansu (height above sea level 950-1100 rice) and Southern Shaanxi (height above sea level 350-1500 rice) etc. ground.Also there is distribution Korea, Japan, Caribbean area.
Long Rhizoma Dioscoreae tuber is medicine-food two-purpose food materials, is also important tuber vegetable, or multiple Far-away Backward Areas is special Being the local speciality in mountain area, the most famous has Ya'an Sichuan province Erlongshan Mountains Rhizoma Dioscoreae, Anshun of Guizhou Rhizoma Dioscoreae, Yunnan sieve time Rhizoma Dioscoreae, cloud Yaoan, south Rhizoma Dioscoreae, Feng County, Jiangsu Rhizoma Dioscoreae, Guannan, Jiangsu Rhizoma dioscoreae, Ruichang, Jiangxi Rhizoma Dioscoreae, Gaoyang, Gaoyang, Hebei fiber crops Rhizoma Dioscoreae, Hebei peace Rhizoma Dioscoreae, Lixian County, Hebei fiber crops Rhizoma Dioscoreae, Jiaozhuo, Henan RHIIZOMA DIOSCOREAE fr0m Henan of China, Henan temperature line Rhizoma Dioscoreae, Xiangyang, Hubei Rhizoma Dioscoreae, Lichuan County, Hubei for no reason Rhizoma Dioscoreae, state, Weihe River Basin, shaanxi Province Nanhua Rhizoma Dioscoreae, Pishan Rhizoma Dioscoreae and Pingliang, Gansu Rhizoma Dioscoreae etc..
Seven, Rhizoma Dioscoreae processing
The eating method of Rhizoma Dioscoreae based on fresh Rhizoma dioscoreae section, drink raw yam slice, food Rhizoma Dioscoreae powder;The existing best eating method of Rhizoma Dioscoreae is to take Boil, Baoshang or steamed wheaten foods;Although the use of Rhizoma Dioscoreae powder is convenient, assimilation effect is optimal, but does not popularize, and main cause is mountain The plant alkaloid contained in Escin contained in coating or mucus, a few peoples' contact can cause Rhizoma Dioscoreae allergy to itch, have the fear heart Reason.
It is by Exposure to Sunlight, baking after section by fresh Rhizoma dioscoreae that the Rhizoma Dioscoreae powder processing method generally taked at present is mainly two kinds: one Bake and wait dried directly grinds, Rhizoma Dioscoreae powder ripening, reconstitute the most at any time and drink.Two is to use spray drying technology, true After empty dry technology or Freeze Drying Technique, the Rhizoma Dioscoreae powder that reprocessing makes, such Rhizoma Dioscoreae powder is that moisture is low but do not have There is processed to process, have certain toxin because of in the Rhizoma Dioscoreae made a living, be not suitable for reconstituting at any time drinking.
Parched with bran is one of Rhizoma Dioscoreae medicinal tradition concocted method, refers to the process of preparing Chinese medicine stirred by Rhizoma Dioscoreae raw cook with a certain amount of Testa Tritici Method.Someone with thin layer chromatography scanning respectively to Rhizoma Dioscoreae and the water-soluble extractives of 3 kinds of different processed products, ethanol-soluble extractives It is determined with the active component Content of Allantoin of Rhizoma Dioscoreae.Found that 4 kinds of sample water-soluble extractivess and alcohol-soluble leach Thing content basic simlarity, Content of Allantoin is then that parched with bran product are the highest.Wang Haibo of Nanjing University of Traditional Chinese Medicine et al. uses simultaneously HPLC method determines the content of allantoin in dried rhizoma of Dioscorea opposita before and after parched with bran respectively, it has been found that in Rhizoma Dioscoreae (parched with bran), Content of Allantoin is the highest, recognizes The dissolution of allantoin in dried rhizoma of Dioscorea opposita is conducive to for parched with bran.
Additionally, have invention disclosed provide a kind of by low temperature baking device manufacture without any additive Pure natural low temperature bakees ripe Rhizoma Dioscoreae powder, and this production technology is simple, and with short production cycle, made Rhizoma Dioscoreae powder can keep Rhizoma Dioscoreae Former perfume (or spice), powder is fine and smooth, moisture, sterilization thoroughly, long shelf-life, instant edible, but be still difficult to popularization and come.
Also having a kind of mode is will to clean the Rhizoma Dioscoreae removing epidermis or process the substandard relic that Rhizoma Dioscoreae dry tablet is left over, Send into defibrination in fiberizer.Being sieved twice with 80 mesh scalpings and 100 mesh dusting covers respectively by levigate slurry, screening thing is sent into centrifugal Machine, centrifugal rotation 5 minutes.Again precipitated powder is sent into baking operation.At a temperature of 40-50 DEG C, dry that to reach 10% to moisture left Right.By pulverizing after drying, screening, after 100 mesh or 120 mesh sieves, it is finished product, uses plastic bag or vial etc. to hold Device is packed.
Experiment finds to use and processes Rhizoma Dioscoreae at different processing modes, the mucilagenous viscosity change of fresh Chinese yam and mucus In matter protein content change correlation, wherein the complex of polysaccharide-protein be affect Rhizoma Dioscoreae viscosity main because of Element, every complex causing Chinese yam polysaccharide-protein destroys the factor decomposed, and such as acid-base value, water temperature, time etc., also affects Rhizoma Dioscoreae viscosity, selects at about pH8, adds water less as far as possible, and temperature should not be the highest, and beating time should not oversize be comparatively ideal processing Mode.
Eight, the mouthfeel of rice made products
Although China's rice quality is also classified into four grades, but determines grade according to machining accuracy, mouthfeel assessment is at China's mesh Front or blank.
Traditional view is thought, the quality of rice sees rice, and saying of hard spot is sustained, and soft saying is soft glutinous.
Inside rice made products, the mouthfeel after processing is selected, the most significantly distinguishes, be northern " sweet dumplings " and southern " ball of glutinous rice ", are not only material choice general rice or the difference of waxy rice here, and a maximum difference is, " unit Night " use directly pulverize after rice flour, " ball of glutinous rice " rice to be stepped up hangs starch.
Advancing by leaps and bounds in recent years from " ball of glutinous rice " commercialized degree, " sweet dumplings " but shows weak, it can be seen that rice hang slurry Technique has occupied very important status in rice made products.
Nine, Rhizoma Dioscoreae starch and the characteristic of rice starch
Compared with other Structure of Starch Granules In Cereals, rice starch granule is the least, and between 2~8 μm, and granularity is homogeneous.Gelatinizing Rice starch water suction fast, the most soft and smooth similar butter of matter structure, there is the mouthfeel of fat, and easily smear out.
The amylose amount of general rice is less than 40%, Semen Oryzae amylose content 23-27%, Semen oryzae sativae amylose 16- 21%, having dramatically different with both is that the amylose content of Oryza glutinosa (also dividing Xian Oryza glutinosa, milled round grain glutinous rice) is almost nil, the most all Being amylopectin, this is also " glutinous " property place.Semen setariae and yellow Oryza glutinosa, purple rice and Oryza glutinosa, have this species diversity.
Many rice varieties, the resistance starch content in its raw rice is the highest, but after boiling, its resistant starch immediately drops to The lowest, as general rice or lower, become the high-resistance starch rice of a kind of artefact.
There is researcher that preparation and the character thereof of Rhizoma dioscoreae resistant starch have been carried out preliminary study in recent years, optimize enzyme Solution-autoclave process prepares the process conditions of resistant starch, and resistant starch yield reaches 16.47%;Use Acid denaturation and the method for boiling water bath Preparing resistant starch, compared with ative starch, resistant starch acid resistance, opposing enzymolysis ability strengthen, and hygroscopicity increases.
Additionally, find the mensuration of Rhizoma Dioscoreae starch, Rhizoma Dioscoreae starch alkali resistant ability is stronger.The granule profile of Rhizoma Dioscoreae starch is mostly Being circular or oval, dissolubility, swelling degree raise with temperature and increase, and for typical compound expansion process, belong to restricted type Expansion starch.The dissolubility of Rhizoma Dioscoreae starch, swelling power, transparency are higher than corn starch, lower than potato starch, are not susceptible to stick with paste Changing, the retrogradation of paste is very fast, and the viscosity of Rhizoma Dioscoreae starch is all had an impact by concentration, temperature, acid-base value.Along with the rising of temperature, Rhizoma Dioscoreae The viscosity of starch is gradually lowered;Along with the increase of concentration, the viscosity of Rhizoma Dioscoreae starch also increases.
After Rhizoma Dioscoreae starch gelatinizing, most of can formation has the certain elastic and translucent gels of intensity, and its character is between solid Between body and liquid.The characteristic mouthfeels to processing, processability and the food of starchy food product such as the viscoelasticity of gel, intensity Deng there being large effect.R1A1Freitas et al. utilizes the Rhizoma Dioscoreae starch gel after DSC method research cold preservation 24h and para arrowroot Finding after powder gelling properties, the activation energy of Rhizoma Dioscoreae starch gel is higher, and its gel strength is bigger than tapioca gel.A lves etc. People utilizes squeezing and pressing method prepare Rhizoma Dioscoreae starch and have studied the impact on Rhizoma Dioscoreae starch gel of the various condition, and result shows, the highest (24%) gel strength and formed under the humidity of minimum (18%) is bigger, relative to non-extruded starch, the starch gel of extruding preparation Glue rate of ageing will be more slowly.
Ten, rice starch is aging
No matter being consumed as staple food, or make mouthfeel and the acceptance of other products, rice and goods thereof as primary raw material Degree all can be by one important physical property of starch---and-aging (bringing back to life) characteristic is affected, and aging characteristics are also that restriction is big The principal element of rice made products product quality.
Meeting is hardening in storage for starch gel after gelatinizing, become fragile, water holding capacity is gradually deteriorated.This is due to starch Long-term ageing caused by.Long-term ageing is mainly amylopectin outer layer short chain and resets the result of crystallization, and outer layer short chain passes through hydrogen bond It is cross-linked to each other and re-forms ordered crystal structure.Short chain content is the most, and the crystal grain of formation is the most, beneficially the accumulation of crystal, knot Crystalline substance degree will be the highest, so degree of aging is the biggest.
Rice glutinous matter starch is chain length distribution average compared with Semen Maydis glutinous matter starch due to amylopectin branched chain, and aging meeting is tighter Weight.
Use heating can suppress the ageing process of rice flour with the physical method stirred, and rice starch is not had effect, this It is that physical modification makes the structure of protein there occurs change, enhances emulsification property, strengthen associating of albumen and starch, improve Retentiveness, thus inhibit the recrystallization of starch molecule.
Use additive can heat at rice starch, cool down and in storage, by the effect with starch component, change Become some physical property of rice starch system, thus the aging generation on rice starch affects.
Have it is demonstrated experimentally that cereal products add Rhizoma Dioscoreae, not only increase oxidation resistance, slow down deteriorating time, Obvious inhibiting effect is had to cereal starch is aging.
Summary of the invention
The invention aims to solve the deficiencies in the prior art, it is provided that a kind of rice made products using Rhizoma Dioscoreae modified And preparation method thereof, widen coarse grain staple food grain path, also promote new year cake rice flour from the effect of single offer diet energy toward merit Can change in food direction.
For achieving the above object, the technical solution used in the present invention is as follows:
The preparation method of a kind of rice made products using Rhizoma Dioscoreae modification, comprises the steps:
Step (1), the preparation of long Rhizoma Dioscoreae granule:
(1.1) preparation of the long yam slice being dried: take after fresh long Rhizoma Dioscoreae is cleaned and remove the peel, is cut into the thick sheet of 3-5mm, is then immersed in protecting Color liquid soaks 2-3h, takes out, then use cold drying mode to be dried by the yam slice after color fixative to water content less than 15%, Store for future use;Containing vitamin C, citric acid and sodium chloride in described colour-keeping liquid, wherein, ascorbic mass concentration is 0.3%, The mass concentration of citric acid is 0.5%, and the mass concentration of sodium chloride is 0.6%;
(1.2) parched with bran is concocted and is ground: with high heat by after pot burn-out, is sprinkled into Testa Tritici to when playing cigarette, puts into step (1.1) and be prepared into The long yam slice being dried arrived, takes out when long yam slice to the surface that constantly stir-fries is ecru;After sieve goes wheat bran to dry the process of preparing Chinese medicine Yam slice, be ground into 1/3rd grain of rice sizes granule storage standby;
Step (2), rice hangs the preparation of starch:
(2.1) preparation of rice serosity: by rice clean water soak at room temperature 2-3 hour, the rice after then soaking adds Quality is that its water of 2-3 times carries out defibrination, obtains rice serosity;
(2.2) hang slurry and be dried: rice serosity step (2.1) obtained hangs slurry mode, or mechanical compaction mode by tradition That makes aqueous 40-60% hangs lumps, then will hang lumps and use cold drying mode to dry rapidly aqueous to be less than less than 15%, Be then comminuted into the granule of 1/3rd grain of rice sizes, obtain rice hang starch storage standby;
