Abstract
The invention relates to a processing method of lotus nut buffing powder. The processing method comprises the following specific steps of: lotus nut buffing powder, screening, distribution, enzyme adding, liquification and hydrolyzing, enzyme deactivation, diatomite filtration-centrifugal filtration, and vacuum concentration (drying), so that a product is obtained. The processing method provided by the invention has the advantages that during the process, moderate-temperature amylase and protein enzyme are adopted for performing enzymolysis under the condition that the temperature is 50-80 DEG C, the starch liquefacation in buffing powder generates oligosaccharide such as dextrin, trisaccharide and disaccharide, meanwhile, the protein is hydrolyzed into polypeptide and amino acid, and a hydrolysate can be used for fully removing impurities such as sand through the diatomite filtration and centrifugal separation; the hydrolysate remains nutrition in the lotus nut buffing powder and health care components, and the processing method is used in food burdening field of cakes and biscuits and the like.
Description
Technical field
The present invention relates to lotus seeds mill skin pink collar territory, be specifically related to a kind of processing method of lotus seeds mill skin powder.
Background technology
Lotus seeds mill skin powder is the accessory substance producing in lotus seeds machinery decortication process, accounts for greatly 20% of lotus seeds raw material.Mill skin powder is nutritious, health care value is high, contains protein more than 19%, carbohydrate 60% left and right, the health-care components that also has vitamin, mineral matter and other lotus seeds to have.Because mill Pi Fenzhong contains sand (sand that sand milling wheel comes off in mill skin process), sand is very thin, and existing mechanical separation method is difficult to separate from mill Pi Fenzhong, and major part can only be worked as offal treatment, causes and large waste.
At present the main application of lotus seeds mill skin powder is as feed or as the culture medium (number of patent application 201210242920.5) of mushroom, has recently people to be added into (patent application 201310012794.9) in yellow rice wine.How lotus seeds mill skin powder is processed but all do not relate in these prior aries, in removing sand, farthest utilized the nutritive value of lotus seeds mill skin powder.
Summary of the invention
For making full use of the accessory substance lotus seeds mill skin powder producing in lotus seeds process, the present invention proposes a kind of processing method of lotus seeds mill skin powder, the method adopts enzymolysis, starch liquefacation in mill skin powder is produced to compound sugar, the proteolysis such as dextrin and become polypeptide and amino acid, by diatomite filtration and centrifugation, sand can be removed completely, hydrolyzate has retained the nutrition and health care composition of mill skin powder, after concentrated or concentrate drying, can be for the food ingredient such as cake and biscuit field.The method products obtained therefrom quality is high, farthest utilizes the nutritive value of lotus seeds mill skin powder in removing sand.
Technology path of the present invention is: lotus seeds mill skin powder → sieve → allocate → enzyme-added liquefaction and the hydrolysis → enzyme → diatomite filtration → centrifugal filtration → Vacuum Concentration that goes out (being dried) → product.
For achieving the above object, technical scheme of the present invention is:
A processing method for lotus seeds mill skin powder, concrete steps are:
1) sieve: lotus seeds are ground to skin powder and cross 80-120 mesh sieve, remove lotus nut and other large granular impurities in mill skin powder;
2) size mixing: the lotus seeds mill Pi Fenzhong after sieving adds water, and powder slurry concentration is adjusted to 16 Be-20Be, obtains slurry;
3) enzyme-added liquefaction and hydrolysis: add middle temperature amylase and protease in slurry, the 20-40 minute that liquefies at the temperature of 50 DEG C-80 DEG C, measures through rare Iodine test, is terminal in the time reacting to rufous, is now warmed up to 100 DEG C and kills enzyme, obtains enzymolysis product; The diastatic addition of described middle temperature be every gram of lotus seeds mill skin powder with enzyme amount be 6-10 unit; The addition of described protease is the 0.2%-1% of lotus seeds mill skin powder consumption;
4) filter: by enzymolysis product diatomite filtration, the filtrate centrifugation 20 min-30min after filtration, gets supernatant;
5) concentrated: by supernatant vacuum evaporation, being concentrated into solid content is 40%-70%, obtains concentrated product.
Preferably, in described in step 3), warm diastatic addition is that every gram of lotus seeds mill skin powder enzyme amount is 8-10 unit; The addition of described protease is the 0.6%-0.8% of lotus seeds mill skin powder consumption.
Further preferably, in described in step 3), warm amylase is middle temperature 7658 amylase; Described protease is papain.55-60 DEG C of papain optimum temperature (general 10-85 DEG C all can, heat resistance is strong), middle temperature 7658 amylase optimum temperatures 60-70
οc.This technique is carried out enzymolysis under the temperate condition of 50-80 DEG C, has ensured the activity of two kinds of enzymes, has retained to greatest extent the nutrition and health care functional mass of mill skin powder simultaneously.
Filtration described in step 4) is divided into diatomite filtration and centrifuge filters, and wherein diatomite filtration is mainly to remove large suspension, and centrifuge filters the sand of bringing into for removing mill skin powder.
Preferably concentrated product described in step 5) is dried, makes biodiversity content below 3%.
Described dry being preferably: concentrated product, through heat exchanger heats to 110 DEG C-120 DEG C, is sprayed in hothouse and arrives moisture below 3% with the hot-air contact drying of 150 DEG C-200 DEG C through nozzle with high-pressure pump.
The present invention is taking lotus seeds mills skin powder as raw material, through sieving, size mixing, enzyme-added liquefaction and hydrolysis, filtration, concentrated and dry, obtains for the production of cake and biscuit batching.Warm starch liquefacation enzyme and protease in this process using, carry out enzymolysis at 50-80 DEG C, the starch liquefacation that makes to grind in skin powder produces the compound sugar such as dextrin, trisaccharide, disaccharides, proteolysis becomes polypeptide and amino acid simultaneously, hydrolyzate, by diatomite filtration and centrifugation, can be removed the impurity such as sand completely.In hydrolyzate, retain the nutrition and health care composition of mill skin powder, after concentrate drying, for the batching of cake and biscuit production.
Compared with prior art, advantage of the present invention is:
1, the processing method of of the present invention kind of lotus seeds mill skin powder, removal of impurities is thorough, making to grind skin powder turns waste into wealth, mill skin powder solution becomes clear solution under amylase and protease effect, by diatomite filtration and centrifugation, the impurity such as sand are removed completely, and making to grind skin powder becomes edible raw material.
2, the method adopts enzymolysis, the starch liquefacation in mill skin powder is produced to compound sugar, the proteolysis such as dextrin and become polypeptide and amino acid, and hydrolyzate has retained the nutrition and health care composition of mill skin powder.
3, the method products obtained therefrom quality is high, farthest utilizes the nutritive value of lotus seeds mill skin powder in removing sand, protein (amino acid) >=12%, and dextrin and compound sugar >=50%, the shelf-life reaches more than 1 year.
