Description

A kind of processing method of potato fermentation Flour product
Technical field
The present invention relates to field of food, and in particular to a kind of processing method of potato fermentation Flour product.
Background technology
Fermentation Flour product generally refer to using wheat flour as primary raw material, by with face, fermentation, shaping and decatize shortening and Into a kind of wheat powder instant noodles food.
Flour product of fermenting kind mainly includes the main Types such as solid steamed bun, steamed twisted roll, loin chop, steamed stuffed bun and lightly fried dumpling steamed bun.
Solid steamed bun is steamed bun in the narrow sense, also known as " steamed bun ", " steamed bun ", " volume cake ", " big steamed bun ", " steamed bun ", " bun ", " face head " etc..Such product is using single flour or several flour as major ingredient, and other are auxiliary for general less addition in addition to leavening Material (addition auxiliary material to produce designs and varieties steamed bun), by with face, ferment and the food that technique is process such as steam.
Steamed twisted roll can be described as layer volume steamed bun, be dough after rubbing and rolling into piece, the alternate stacking of different dough sheets or applied on dough sheet One layer of auxiliary material is smeared, then rolls to form different colours level or separation level, is formed again by turning round volume or folding after also rolling Various pattern shapes, then proof and steam as steamed bun kind attractive in appearance and nice, there are many kinds of patterns.Steamed twisted roll taste is only Spy, the flavor that can more embody auxiliary material is simply mixed than two or more simple materials, and forms obvious sensory difference and be in A kind of existing special pleasure of the senses.
Steamed stuffed bun is a kind of band filling steamed bun, is that fermented dough is rolled into musculus cutaneus, a kind of band filling of bag people's fillings kneading shaping steams Wheaten food processed.Product cladding is warm and sunny soft, the flavor of prominent fillings, has the unique taste, deep to be welcome by national people.The species pole of steamed stuffed bun It is more, it is generally divided into big bag (50 1 80g wheat flours are cooked 1 one 2), parcel (50g wheat flours are cooked 3 one 5) two classes.Large and small steamed stuffed bun In addition to attenuation degree is different (big steamed stuffed bun fermentation foot, small steamed stuffed bun Fermented), small steamed stuffed bun shaping, heart of filling are all relatively finer, more with small Cage steams, and with bag with steaming with selling, in some places of south, this kind of small steamed stuffed bun of fermentation is referred to as steamed bun.In terms of shape, it is further divided into Carry pleat, autumn leaves, pincers flower, Buddha's hand, Taoist priest's cap etc..From heart of filling taste, also there is sweet tea salty other.
Loin chop includes fermentation loin chop, steamed cake, characteristic loin chop, wherein, fermentation loin chop is also known as steamed sponge cake, be it is a kind of very Warm and sunny soft steamed bun, its dough preparing obtain relatively soft, even pasty state, through everfermentation, are molded, proof, steam.Product is most For sweet taste.Common steamed sponge cake has coarse cereals steamed sponge cake, big fermented rice cake, cream steamed sponge cake etc..Often add when coarse cereals or rice flour production steamed sponge cake Add a certain amount of wheat flour to increase dough holds gas.Traditional steamed sponge cake is that raw material is modulated into pasty state, after fermented, is poured into The shapes such as square, rhombus or triangle are cut into after being steamed in mould.Raw material is modulated into soft dough by many steamed bun factories now, through hair Ferment moulding or the direct moulding of azymic, then fully proof, the product steamed can keep shape, and often stick in product surface Some preserved fruits, sesame, raisins etc. are decorated, and can also carry out mounting colored decoration after product cooling.Steamed cake with egg, Flour and white sugar are primary raw material, are bubbled by beating egg, and admixing flour and holding the method for gas makes product soft.In steamed cake High-titer protein content is high, because steaming, compared with being baked, temperature is low, and the validity of protein is more preferable.Its with egg fragrance and Very soft tissue characteristics, it is the food kind for having very much development potentiality.But it needs without the burnt odor flavor and taste of baking Appropriate regulation flavor, makes it be welcome by more people.Characteristic loin chop with different flour admix some have flavour and The dispensing of color and luster, dough or batter are modulated into, is formed by steaming.Its flavor and outward appearance are special, typically with local characteristic.
Lightly fried dumpling steamed bun is also known as burnt bottom steamed bun, eschar steamed bun, is in shortening, and decatize and heated kang heat simultaneously, and product is special Point is that surface and the sense of organization are identical with other cooking foods, and the sallow delicious and crisp in bottom surface, and it is very special to be that China's folklore gets off Other food.Before there is not aluminium pan, China common people are with sharp floor iron pot cooking and cook, in order to save time and energy, Steamed bun, steamed twisted roll or steamed stuffed bun are pasted when cooking in the pot wall of non-waterflooding, when meal is cooked, lightly fried dumpling is also cooked.Afterwards by people's Grope and improve, createed some local characteristic products, as Shanghai Pan-Fried Steamed Bun, Henan lightly fried Chinese bread, field sowthistle herb steamed bun, Shanxi are small The corn lightly fried dumpling in rice cake and Central Plains area etc..
Certain yeast and other auxiliary materials are added in wheat flour, after mixing plus water stirs, and obtains having certain elasticity, modeling Property, the dough of extensibility, the dough are fermented under certain temperature and humidity so that dough rises and has fermenting aroma (sponge dough method without forming operation is directly carried out after this process, and face), then add remaining former, the auxiliary material progress of people secondary and Face, slightly standing makes dough relaxes, after steamed bun making machine shaping and trimmer (rubbing steamed bun machine with the hands) shaping, or dough kneeding machine roller sheet are carried out to dough Knife is cut into type, or rolls skin and wrap into preprepared fillings, is then placed in fermentation room or certain time is proofed in steaming tray, make Dough surface is smooth, volumetric expansion, dough is finally put into steamer, steam tunnel or steamer in decatize shortening.Due to using former The difference of material and molding mode, can obtain the fermentation Flour product product of many kinds.
At present, the production procedure for Flour product of fermenting mainly includes the following steps that:
First, dispensing with and face, and face be also known as dough preparing, adjust powder, stirring, kneading, be fermentation Flour product production in most One of crucial process.
2nd, dough fermentation;Dough fermentation is after the various supplementary materials such as flour stir into dough, when generally requiring by one section Between fermentation process.Fermentation Flour product base only can just process enlarged volume through everfermentation, and soft texture is flexible, and mouthfeel is dredged Pine, the tempting product of flavor.
3rd, Flour product of fermenting shaping and shaping, fermentation Flour product shaping include fermenting Flour product machine are molded and kneaded dough and hand Work is molded two kinds, and fermentation Flour product machine typically has a shortcoming, and the molding effect Flour product machine that preferably ferments is expensive, and body Product is larger, is unfavorable in the popularization and application of small-sized fermentation Flour Products Mill.Fermentation Flour product machine makes fermentation Flour product green compact have one More fixed shape and appearance more attractive in appearance, still, green compact made from traditional fermentation Flour product machine or have save bar, or shape Shape differs.Thus, the shaping to the Flour product green compact that ferment seems very necessary.
4th, dough proofs;Proof also known as treacle hair, treacle steamed bun.Proof be dough last time fermentation, control temperature and Under conditions of humidity, make it is shaped after dough (fermentation Flour product base) reach due volume and shape.It is fermentation face system Product produce a vital step, its success or failure operated, directly affect the terminal quality of product.
5th, fermentation Flour product steams;Decatize is to steam the shortening process of wheaten food processing, and the difference of mode of heating to ferment Flour product is different from bread, and has the distinctive flavor of fermentation Flour product and nutrition.During steaming, there occurs a series of for product Physics, chemistry and biochemical change.With respect to west for the research of baking process, China's tradition steams the research of technique It is also very shallow.
6th, cooling and packaging;For the ease of large-scale production and a wide range of sale, fermentation Flour product must cool down, and then wrap Dress.If Flour product of fermenting, without appropriate cooling, because temperature is high after packaging, caused water vapor condensation forms water droplet, is attached to Packaging bag and fermentation Flour product surface, thus Flour product epidermis whiting of fermenting, are easy to corruption.General fermentation Flour product is cooled to 50 Pack ideal at one 60 DEG C, so unnecessary vapor will not both be evaporated and lose internal moisture, and keep product Softness, also will not because of high temperature and caused by dew in packaging bag.It is determined that it is very that it is ideal, which will to lose how much water, for fermentation Flour product Difficult, because this must be determined depending on product packaging and storage situation.General fermentation Flour product factory all lacks cooling device, Allow its natural cooling.But due to the variation in season, the temperature and humidity of air can all change, so should rule of thumb be subject to Adjustment.The warm-served food sale of the product or store in front of workshop of general insulation sale then slightly cools down, and does not cool down even and also may be used.Fermentation The migration and evaporation of moisture occur after taking the dish out of the pot for Flour product, and the gradual weightlessness of product is hardened.Except appearance has one layer of table after taking the dish out of the pot Outside skin, almost each section is all highly uniform for the temperature for Flour product of fermenting, but moisture distribution and uneven, exocuticle moisture It is more.After taking the dish out of the pot, epidermis cools rapidly, moisture elder generation rapid evaporation, then occurs evaporating and condense while carry out.Inside is due to temperature Height, moisture spread to fermentation Flour product low temperature crust.The distribution of moisture and the result of variations of temperature, moisture are distributed to table from center Skin, then by epidermis be evaporated to outside air.The most important reason of moisture evaporation is the effect of vapour pressure, vapour pressure and temperature phase Close, it is bigger that temperature is cured high-vapor-pressure.The atmospheric vapor in winter forces down, and the epidermis evaporation of fermentation Flour product is fast;The steam of summer air Pressure is high, and the epidermis evaporation of fermentation Flour product is slow.If being air-dried when therefore cooling down, fermentation Flour product evaporates more moisture to reduce Ferment Flour product self-temperature, and this phenomenon is the physical equilibrium phenomenon of nature.The result of a large amount of evaporation moisture causes to ferment Flour product weight substantially mitigates, epidermis hair wrinkle even breach, and fermentation Flour product quality is hardened, and quality is bad.If high humidity, steam Pressure is then small, and fermentation Flour product transepidermal water has appropriate evaporation, and even cooling down will not also make excessive water scatter long again, product Surface is smooth, it is weightless less, tissue it is soft.Therefore, the cooling procedure for Flour product of fermenting should improve ambient humidity as far as possible, avoid doing The blow-through of dry air.In order to improve cooldown rate, can accelerate to cool with moist cold air convection.Between general cooling packing not Can have " draught ", under dry weather conditions, humidification device is disposed in room.The conventional cooling means of Flour product of fermenting It is to be placed on the fermentation Flour product for steamer to steam on car or be poured on cooling bench, allows its natural cooling 20 1 30min.Cooling degree With product non-scald on hand, still there is heat, keep softness to be advisable.Need the production fermentation Flour product that the long period sells in supermarket production During product, need thoroughly to cool down fermentation Flour product, and be stacked in packing case after being hardened.Cooling condition should be according to actual conditions Grope to adjust, be worth reminding, the cooling technique condition of Various Seasonal should be different.Product packaging;When fermentation face system When product centre is cooled to 50 1 60 DEG C, it should be packed immediately.Such as continue to be exposed in air for a long time, Flour product of fermenting Product easily aging, fungal infection, moisture loss is too big, influences flavor and taste.It is old that product packaging can postpone fermentation Flour product Change, the hard drying of fermentation Flour product after age of starch, fuse is nonelastic, both influences flavor, and the digestion for reducing human body again is inhaled Yield.Aging phenomenon is the inexorable trend in fermentation Flour product storage, but the product after packaging can be acted on delaying aging, and it is former Cause is that fermentation Flour product preserves in the state of relative constant humidity, is not easy dehydration, delays the aqueous phase separation of starch-hydrocolloid to act on, Colloid dehydration is also the major reason of aging.Re-heat is needed before the fermentation Flour product of ageing hardening is edible.Product packaging can prevent Pollution, fermentation Flour product is as directly edible food, it is desirable to sanitation and hygiene, prevents from polluting in storage, transport, sales process Foul and mushroom;The fermentation Flour product moisture just to have taken the dish out of the pot is typically 35% one 50%, if proper temperature, has microorganism dirty again Dye, will be easily putrid and deteriorated food.Finished product after packaging prevents from producing infection when contacting with air, container, hand, and prolongs Storage life is grown.Sufficiently cooling and after drying, the preferable packaging material of and can performance, experiment proves, in 30 DEG C of temperature Under the conditions of can store more than 24h.Meanwhile contact of the product with peculiar smell has been isolated in packaging bag, the flavor of existing product is maintained. Product packaging can prevent breakage, and fermentation Flour product does not only have the possibility of pollution in storage, transport and sale, and also has breakage Incomplete disadvantage.The particularly soft product of quality is more easy to occur, with film packaging steamed bun, after can avoiding mutual adhesion It broken skin when taking away, can also play a part of damping, prevent the integrality for colliding, extruding and disfeaturing.Product packaging can beautify Commodity, value is improved, the product after packaging, because of the novel design in packaging and beautiful in colour and very eye-catching, beautifies commodity, Improve product hierarchy.Packaging can also be indicated the manufacturer of product and trade mark, trust consumer.To nutrition in packaging Feature is publicized, it suffices to say that packaging and a kind of form of advertisement, makes product widely known.
Potato, belong to Solanaceae herbaceos perennial, stem tuber can be edible, is the third-largest important cereal crops in the whole world, only Inferior 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, paddy, Sorghum simultaneously turns 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%, slightly Fiber 0.6~0.8%.Contained nutritional ingredient in 100g potatoes: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 yellow Element 0.01~0.04mg, 0.4~1.1mg of niacin.
Potato stem tuber contains substantial amounts of starch.Starch is the main energy sources of edible potato.General early seasonal strain potato contains There is 11%~14% starch, mid-late mature seed contains 14%~20% starch, and the stem tuber of high starch varieties is up to more than 25%. Stem tuber is also containing glucose, fructose and sucrose etc..Potato protein concentrate matter nutritive value is high, and potato stem tuber contains 2% or so albumen Matter, 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 chicken The protein of egg, easily digestion, absorption, better than the protein of other crops.And the protein of potato contains 18 kinds of amino acid, The various essential amino acids that can not be synthesized including human body.The nutritive value of potato is spoken highly of, is to contain high-grade with its stem tuber The protein and lysine of essential amino acid, tryptophan, histidine, arginine, phenylalanine, valine, leucine, different bright The presence of propylhomoserin and methionine is undivided.Potato stem tuber contains multivitamin and inorganic salts.Edible potato is beneficial to strong The effect of health and vitamin is undivided.Particularly vitamin C can prevent scurvy, stimulate hematopoietic function etc., eaten daily Rice, in fine flour be no, 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), vitamin E (tocopherol), vitamin B3 are (general Acid), vitamin B6 (pyridoxol), vitamine M (folic acid) and biotin H etc., be all beneficial to health.In addition, stem tuber In inorganic salts such as calcium, phosphorus, iron, potassium, sodium, zinc, manganese etc., and the indispensable member of growing up to the health and early children development of people Element.Containing abundant dietary fiber in potato stem tuber, and containing abundant sylvite, belong to basic food.There is data expression, it contains Amount and apple are as many.Therefore absorption of the stomach and intestine to potato is slower, and after eating potato, the time rested in enteron aisle is longer than rice It is more, so having more satiety, while can also help to take away some greases and rubbish, there is certain catharsis and toxin expelling to act on. In addition, the stem tuber of potato also contains unexistent carrotene and ascorbic acid in cereal grain.Come from nutritional point See, it has the advantages of more than rice, flour, can supply the substantial amounts of heat energy of human body, can be described as " food perfect in every way ".People It is enough to sustain life if only leaning on potato and whole milk and healthy.Because the nutritional ingredient of potato is very comprehensive, nutrition knot Also relatively rationally, simply the amount of protein, calcium and vitamin A is slightly lower for structure;And this is just supplemented with whole milk.Potato stem tuber water Point more, lean, unit volume heats are at a fairly low, and contained vitamin C is 4 times of apple or so, and B family vitamin is apple 4 times, various mineral matters are several times to tens times of apple, and potato is hypotensive food, and certain nutrition is more in meals Or lack 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, it Containing the B family vitamin such as abundant vitamin B1, B2, B6 and pantothenic acid and substantial amounts of good fiber quality element, also containing trace element, ammonia The nutrients such as base acid, protein, fat and high-quality starch.Potato is carbohydrate, but its content is only equivalent weight 1/4 or so of rice, research shows, the starch in potato is a kind of resistant starch, has the function that to reduce adipocyte.Potato It is extraordinary hyperkalemia hyponatremia food, is well suited for edema type overweight people and eats, enriched plus its potassium content, almost in vegetables most High, so also having the effect of thin leg.It follows that potato has very high nutritive value and medical value, therefore, potato Various products are fabricated to extensively.
Full potato starch is one kind in dehydrated potatoes product, cleaned, remove the peel, select, cutting using fresh potato as raw material Piece, rinse, precook, cooling down, boiling, smashing the technical process such as mud, shape or powdered is considered to be worth doing through fine particulate, piece obtained by dehydrating Product system is referred to as full potato starch, and full potato starch has cured in process, and therefore, there is full potato starch very strong sticking to glue Property, still, its corresponding ductility is poor, and a kind of Flour product base-material is formed after full potato starch is mixed with flour, if should The content of full potato starch is difficult to maintain the original processing characteristics of flour, example more than 25% when making and curing Flour product in base-material Such as, it is poor in the fermentation Flour product bulkiness being fabricated to using the base-material, have a great impact to the mouthfeel for Flour product of fermenting.
Potato starch is with fresh potato, cleans, crushes by raw material, filtering, being dehydrated, drying, at the process such as subpackage Reason forms, have the characteristics that it is pure white it is sparkling and crystal-clear, quality is fine and smooth, viscosity is high, therefore, potato starch has good ductility, but It is that the glutinous viscosity of corresponding potato starch is poor, is not easy a kind of agglomerating, Flour product base of formation after potato starch is mixed with flour Material, if the content of potato starch 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, during fermentation Flour product is made using the base-material, fermentation Flour product is difficult to be molded, it is difficult to process.
Potato fermentation Flour product refers to using flour as primary raw material, and a certain amount of full potato starch or potato are added in flour Starch, facilitate flour-made food by the one kind formed with face, fermentation, shaping and decatize shortening, at present, on potato fermentation face system The processing method of product has a lot, the processing method of existing potato fermentation Flour product be mostly directly by full potato starch directly and face Powder is processed after individually mixing, and due to the characteristic of full potato starch, the full potato starch content added in flour is no more than 25%;Or individually mix potato starch with flour, due to the characteristic of potato starch, the potato starch added in flour contains Amount no more than 25%:Thus, using in potato fermentation Flour product made of the processing method of existing potato fermentation Flour product Potato content is not high, moreover, the content of the potato contained in potato fermentation Flour product is higher, is more difficult to maintenance face in processing The original processing characteristics of powder, its processing characteristics is poor, causes the production efficiency of potato fermentation Flour product relatively low, product qualification rate It is relatively low.

In the process of fermentation Flour product, yeast is very important, and yeast generally has following three kinds, yeast cake, Active dry yeast, send out active dry yeast.
Whether the application method of yeast correct, be directly connected to dough can normal fermentation and fermentation Flour product product matter Amount.The principle of proper use of yeast is that the activity of yeast will be kept in whole production process, will be advantageous to per procedure The abundant breeding and growth of yeast.
1. adding method
Yeast is sensitive to temperature change, and its vital movement and temperature change are closely bound up, and its activity and fermenting power are with temperature Degree changes and changed.The critical process for influenceing yeast activity is dough stirring first, due to overwhelming majority manufacturer of China car Between without air-conditioning equipment, mixer is unable to thermostatic control, and the temperature of dough need to adjust water temperature to control according to seasonal variations.Therefore stirring The addition of yeast should determine according to situations below during mixing.
(1) the multi-purpose 30 1 40 DEG C warm water stirring of season in spring and autumn, yeast can be added directly in water, both ensured yeast in face It is dispersed in group, activation is played again.But when water temperature is more than more than 50 DEG C, ten million can not be put into yeast in water, otherwise ferment Mother will be killed.
(2) early summer season uses cold water stirring, and winter uses hot water stirs.Therefore, the two seasons should first mix yeast Enter to put into mixer in flour again and be stirred, can thus avoid yeast from directly contacting hot water or cold water and inactivate.If yeast Less than 15 DEG C of cold water is touched, its activity substantially reduces, and causes the dough fermentation time to grow, acidity is big, there is peculiar smell.If contact Then it is killed quickly to more than 50 DEG C of hot water.Yeast is mixed in people's flour and is stirred for, then flour first neutralizes water temperature, and yeast is risen The effect of umbrella is arrived.
(3) for season in midsummer room temperature more than more than 30 DEG C, yeast should be dry to be sprinkling upon face before dough stirring completion during 5 one 6min Stirred in group.If stirred together with first being mixed with flour, the phenomenon of gassy fermentation while stirring occurs, makes face Group can not be formed, and have impact on the mixing quality of dough.When summer High Temperature season stirs, ten million can not activate yeast in water, It can so make gassy fermentation in whipping process too fast, more uncontrollable dough quality.
(4) in whipping process, hypertonic material, such as salt, sucrose to be avoided direct contact with as far as possible when yeast adds With dietary alkali etc..
2. usage amount
The application method of yeast is relevant with factors, should be adjusted according to following situations.
(1) fermentation process fermentation times are more, and yeast dosage is fewer, otherwise more.Therefore, no dough fermentation method dosage At most, dough sponge dough method dosage is taken second place, and fermenting twice method dosage is minimum.
(2) if formula has other leavenings such as distiller's yeast assisted fermentation, yeast dosage should be reduced.Answered when adding people's auxiliary material Consider that adjustment yeast dosage, such as the addition of coarse cereals, salt etc. may need to increase yeast dosage.
(3) flour strength is bigger, and dough resistance is strong, should increase yeast dosage;Otherwise yeast dosage should be reduced.
(4) seasonal variations summer temp is high, and fermentation is fast, can reduce yeast dosage;Spring, autumn, winter, temperature is low, should increase Yeast dosage, to ensure dough normal fermentation.
(5) dough soft durometer adds the soft dough more than water, and fermentation is fast, can reduce yeast dosage.The few hard dough of water is added then should Multi-purpose yeast.
(6) water quality using hardness high water when should increase yeast dosage, during the softer water of use, then should reduce yeast use Amount.
(7) between different yeast with magnitude relation due to yeast cake, active dry yeast, i.e. send out active dry yeast fermenting power it is poor Very not big, therefore, they are also significantly different in usage amount.Conversion relation between them is:Yeast cake:Active dry yeast: It is 1 to send out active dry yeast:0.5:O.3.
During dough is prepared, add that the number of water or potato liquid is extremely important, and amount of water is fewer, can make dough Time shortening is rolled, and mixing time should be extended in the extension phase after rolling, so that gluten fully extends.But hypohydration meeting The particle of flour is set to be difficult to aquation, the gluten property of formation is more crisp, and stability is poor.Specific feelings should be regarded in fermentation Flour product production Condition determines the addition of water.If using medium strength flour, and being not added with grease and milk powder, amount of water can be controlled in 43% with Under.If amount of water exceedes this amount, the phenomenon of fermentation Flour product machine roll banding may be caused.
The auxiliary material can be sugar, grease, milk powder, salt, spice, fillings etc..
