Abstract
The invention relates to food processing technologies and in particular relates to a method for preparing sugar-free and smell-free pumpkin powder. The method comprises the following steps: with fresh old mature pumpkins as raw materials, mixing and processing by virtue of a colloid grinding pulping process, a biological enzymatic hydrolysis and smell removal technology, an ultrasonic flocculation effect and a low-temperature sedimentation solid-liquid separation process. According to the method, the smell of the pumpkins is removed and the mouth feel and the solubility of the pumpkin powder are improved. The pumpkin powder prepared by the method is high in soluble dietary fiber content, low in sugar content and suitable for patients with diabetes and hypertension, can serve as a raw material for a mixing process in the food industry and also can be processed and eaten according to personal taste. The method has the characteristics of low cost, low energy consumption and low heat-sensitive nutrition loss.
Description
Technical field
The invention belongs to food processing field, is a kind of method of preparing the de-raw meat pumpkin powder of desaccharification specifically.
Background technology
China's traditional medicine has found that pumpkin has higher medical value and health-care efficacy very early.In the book on Chinese herbal medicine > > of traditional Chinese medical science history records < < the southern regions of the Yunnan Province, record, " pumpkin is warm in nature, taste is sweet tasteless; enter spleen, stomach two warps; energy moistening lung qi-benefitting; the apocenosis of reducing phlegm; expelling parasite removing toxic substances, controls the illnesss such as cough, asthma, lung carbuncle, constipation ".Modern pharmacology disclosed pumpkin have hypoglycemic, adjust blood fat, hypotensive, anti-inflammatory, antitumor and prevent and treat the effects such as artery sclerosis.
In pumpkin, contain rich in protein, amino acid (citrulling, arginine, asparatate etc.), pectin, vitamin (V
c, V
e, V
bdeng) and multi mineral prime element (Zn, Co, Cr, Fe, Mg etc.), contain in addition the various bioactivators such as polysaccharide, alkaloid, Soluble Fiber, beta carotene and lutein, and fat content is low.Polysaccharide in pumpkin can improve the proliferation activity of beta Cell of islet, reduces calcium overload in islet cells, promotes the secretion of insulin.Abundant dietary fiber and pectin substance in pumpkin, can effectively delay the absorption of enteron aisle to sugar and lipid, heavy metal and some radioactive elements such as cytotoxin in human body, part agricultural chemicals and lead cohered, neutralize, removed, and liver, renal function can be helped to weaken the power of regeneration that patient strengthens liver and kidney cells.Meanwhile, the zinc in pumpkin, chromium are the important component parts of insulin, and insulin cell is had to protective effect.
Pumpkin powder is very important food industry intermediate raw material, and the special efficacy health food that the pumpkin of take is produced as raw material, because its unique nutritive value and health-care efficacy are well received by consumers.At present, the production method of pumpkin powder mainly contains following three kinds:
One, through peeling, go the technological process processing such as seed, (pretreatment) are dry, pulverizing and make pumpkin powder, there is poorly water-soluble while reconstituting, the shortcoming that mouthfeel is relatively coarse in the pumpkin powder that this kind of mode produced.
Chinese patent: CN1159891 " with superfine cushaw flour production by air flow pulverizing ", is that fresh pumpkin pulp is diced, and dry airing is made after dried pumpkin, then pulverizes and make pumpkin powder with airslide disintegrating mill.
Chinese invention patent application number 96106800.0 publication number CN1144056A disclose a kind of processing method of large moon pumpkin powder, after the method adopts carbohydrase to soak, dry, pulverize and make pumpkin powder.
Chinese invention patent application number 201210003933.7 publication number CN1025246974A disclose a kind of processing method of pumpkin powder, and the method adopts blanching technique to process pumpkin fourth, and then pumpkin powder is made in drying, pulverizing.
Chinese invention patent application number 201110456698 publication number CN102511751A disclose a kind of processing method of pumpkin powder, and it is raw material that the method is selected " towards southern No. one " pumpkin, after dicing, removes free water, through microwave drying, pulverizes and makes pumpkin powder.
Chinese invention patent application number 201110307455 publication number CN102366061A disclose a kind of production technology of pumpkin powder, and the method is removed seed after adopting clear water to soak, and the method for drying, pulverizing is made pumpkin powder.
Two, adopt making beating, the flow process processing such as concentrated spray is dry and the pumpkin powder made, there is juice poor fluidity in this mode of production, the problem that pumpkin powder yield is low and nutrient loss is large.
Chinese invention patent application number 200710002970.5 publication number CN101002610A disclose a kind of pumpkin powder and processing method thereof, and the method adopts and to squeeze the juice, fine grinding, homogeneous, allotment, the dry processing of spraying and the pumpkin powder made.
Although Chinese invention patent application number 201210348514.7 publication number CN102835633A have adopted the method for pectase and cellulase hydrolysis to solve the problem of spray drying process juice poor fluidity, but still can not avoid heat-sensitive ingredients degraded, nutriment decomposes this problem that runs off.
Three, adopt natural sedimentation after slurrying or centrifugal method is made separately pumpkin powder, the method exists Separation of Solid and Liquid not thoroughly and the shortcoming of long processing time.
Chinese invention patent application number 200810150331.8 publication number CN101623073A disclose a kind of processing method of pumpkin powder, and this method adopts watermill process, natural sedimentation, and filter-press dehydration, then muffin is pulverized, dried and make pumpkin powder.
Chinese invention patent application number 201010042826 publication number CN101731536A disclose a kind of low energy consumption pumpkin powder production process, and this process using making beating, centrifugalization and juice-removing, method dry, that pulverize are made pumpkin powder.
In addition, said method does not all have to propose a solution for this problem of dried pumpkin powder product fishy smell.Although the method for conventional high-temperature boiling can be removed pumpkin fishy smell, also make its thermal sensitivity composition greatly lose.
Chinese invention patent application number 02111589.3 publication number CN1381191A discloses a kind of preparation method of desaccharified deodoured nutritive compoiste pumpkin powder, the method is by after pumpkin juice processed, add strain fermentation 72~120 hours, the dry powder process of spraying, the method can effectively be removed the fishy smell in pumpkin, but it is longer to remove raw meat required time.
Summary of the invention
Object of the present invention, is to propose a kind of new method of preparing the de-raw meat pumpkin powder of desaccharification, and the method can improve the production efficiency of product effectively, avoids the waste of resource; Adding of biological complex enzyme contributes to reduce juice viscosity, effectively reduces the resistance of Separation of Solid and Liquid, and reaches the object of de-raw meat; Adopt colloidal grinding pulping process assistance enzymolysis deodorization technology, can reach effective fragmentation and shorten the double effects of enzymolysis time; Utilize ultrasonic wave flocculating effect in conjunction with low temperature sedimentation solid-liquid separation process, can greatly improve the rate of departure of non-even phase material, and effectively prevented the decomposition of heat-sensitive substance, above method has overcome the shortcoming and defect of existing production method, strengthened again the quality of this intermediate raw material, this method is that independent pulping process and independent enzymolysis processing method do not reach at all.
