A kind of processing method of potato flour
Technical field
The invention belongs to flour processing technical field, and in particular to a kind of processing method of potato flour.
Background technology
Flour is the staple food of north of China most area, and food variety is various made of flour, is made a lot of variety, flavor
Totally different, conventional flours are a kind of powders worn into by wheat, and with the improvement of living standards, people are for healthy understanding
Horizontal original higher, health turns into public concern feelings, and the flour of various kinds arises at the historic moment, and wherein potato tubers contains
Substantial amounts of starch, there is good development prospect, potato protein nutritive value height as flour.Potato tubers contains 2%
The protein of left and right, protein content is 8%~9% during potato is dry.It was found that the protein nutritive value of potato is very high, its product
Matter is equivalent to the protein of egg, easily digestion, absorption, better than the protein of other crops.And the protein of potato contains
There are 18 kinds of amino acid, including the various essential amino acids that human body can not synthesize.Speak highly of potato nutritive value, be and its
Stem tuber contains lysine, tryptophan, histidine, arginine, phenylalanine, the figured silk fabrics ammonia of high-grade protein and essential amino acid
The presence of acid, leucine, isoleucine and methionine is undivided.Ingredient in general fresh potato:Starch 9-
20%, protein 1.5-2.3%, fatty 0.1-1.1%, contained nutritional ingredient in crude fibre 0.6-0.8%, 100g potato:Energy
Measure 318 kilojoules, calcium 5-8mg, phosphorus 15-40mg, iron 0.4mg-0.8mg, potassium 200-340mg, iodine 0.8-1.2, carrotene 12-
30mg, thiamine 0.03-0.08mg, riboflavin 0.01-0.04mg, niacin 0.4-1.1mg.
Potato is processed into flour there is the problem of starch colloidality difference, water imbibition is bad, hardly possible fermentation, formability of fermenting
Difference.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of processing method of potato flour, to potato
Handled, farina is modified, obtained flour muscle degree is improved, and can be processed into miscellaneous dessert.
The present invention is achieved by the following technical solutions:
A kind of processing method of potato flour, comprises the following steps:
(1)Prepare following component in parts by weight:Potato 120-130 parts, cassava 20-30 parts, Chinese yam 20-25 parts, Job's tears
Benevolence 15-20 parts, longan 10-15 parts, lotus root piece 10-12 parts, matrimony vine 7-9 parts, extract solution from aloe 1.0-1.5 parts, Semen sojae atricolor extract
0.5-1.0 parts;
(2)After new potato is cleaned up, surface moisture is air-dried, is put at 0-5 DEG C and stores 20-30 days, storage period is kept
Relative air humidity is 70-80%, and carries out shading, obtained peeling potatoes stripping and slicing, using containing Radix Angelicae Sinensis, prepared rhizome of rehmannia, the root of herbaceous peony,
Peach kernel, the herb liquid immersion 2-3 hours of root tuber of aromatic turmeric, the potato ball after immersion is ground into pureed;
(3)Cassava, Chinese yam are removed the peel, it is 10-12% to be air-dried with coix seed, longan, lotus root piece and matrimony vine to water content, is air-dried laggard
Row milling, obtains the particle diameter of 300-350 mesh sizes, is added to step(2)In the mashed potato of preparation, then by extract solution from aloe,
Semen sojae atricolor extract is added in mixture, after being well mixed, puts into expansion extruder, and extrusion temperature is 160-180 DEG C, is obtained
To potato flour.
Further described as to such scheme, step(1)Middle extract solution from aloe is obtained using alcohol extracting method, alcohol extracting temperature
For 50-60 DEG C, Semen sojae atricolor extract is obtained using water extraction, and water extraction temperature is 80-90 DEG C.
Further described as to such scheme, step(2)The herb liquid is in parts by weight by following component system
Into:Radix Angelicae Sinensis 18-21 parts, prepared rhizome of rehmannia 15-18 parts, root of herbaceous peony 11-13 parts, peach kernel 8-10 parts, root tuber of aromatic turmeric 6-8 parts, water 700-750 parts.
Further described as to such scheme, step(3)Middle Extruding particle size is 400-450 mesh.
The present invention has advantages below compared with prior art:It is processed into flour in order to solve existing potato there is shallow lake
Arogel is poor, and water imbibition is bad, hardly possible fermentation, ferment formability difference the problem of, the invention provides a kind of potato flour plus
Work method, after new potato is cleaned up, surface moisture is air-dried, is put at 0-5 DEG C and stores 20-30 days, storage period is kept
Relative air humidity is 70-80%, and carries out shading and potato is handled, and farina is modified, and potato is formed sediment
The problem of arogel is poor, and water imbibition is bad is resolved, and is soaked using the herb liquid containing Radix Angelicae Sinensis, prepared rhizome of rehmannia, the root of herbaceous peony, peach kernel, root tuber of aromatic turmeric
Bubble, improve the nutritive value of potato, addition extract solution from aloe, Semen sojae atricolor extract, it is possible to increase the storage period of flour, from
Insect pest, obtained flour muscle degree are improved, and can be processed into miscellaneous dessert.
