Description

Instant tartary buckwheat nutrition powder
Technical Field
The invention belongs to the technical field of comprehensive processing of tartary buckwheat, and particularly relates to instant tartary buckwheat nutritional powder.
Background
Solid beverages are becoming a focus of increasing attention because of their convenience in carrying and storage. Meanwhile, with the rapid development of society, the number of patients suffering from modern diseases such as hypertension, hyperglycemia, hyperlipidemia, obesity, etc. caused by excessive intake of refined food is gradually increasing. Therefore, research and development of meal replacement powder with low sugar demand are continued.
The tartary buckwheat is a traditional crop, contains multiple bioactive substances such as polyphenol, protein, polysaccharide and the like, and also has multiple physiological functions such as oxidation resistance, cancer resistance, blood pressure reduction, blood sugar reduction, cholesterol reduction and the like. At present, the number of patents related to the tartary buckwheat nutritional powder is large, but the nutritional powder has poor dissolving performance and long dissolving time, so that the eating experience of consumers is poor.
The patent with publication number CN103919230A discloses the preparation of an instant solid beverage of tartary buckwheat and quinoa. The patent adopts mixing, granulating and infrared drying to prepare the instant solid beverage, wherein the content of active substances in the tartary buckwheat is limited, the energy generated by infrared drying is higher, and the nutritive value of the tartary buckwheat is reduced by easily modifying the nutritive substances in the tartary buckwheat.
Therefore, research and development of the tartary buckwheat nutrition powder which has good dispersion speed and maintains the nutrition components of the tartary buckwheat are urgently needed.
Disclosure of Invention
We find that the content of soluble substances in the tartary buckwheat and the water absorption degree of starch and dietary fiber in the tartary buckwheat can be improved by steel grinding and high-pressure cooking of the tartary buckwheat, so that the instant solubility of the product is improved, and the konjac powder is matched to increase the intestinal tract peristalsis, improve the retention time of the nutrition powder in intestines and stomach and increase the satiety; and the stabilizer low-PI resistant dextrin and the sucrose fatty acid ester are adopted to improve the stability and the dispersibility of the product during eating, and the non-nutritive sweetener is added, so that the low-PI resistant dextrin and the sucrose fatty acid ester are suitable for people with low-sugar intake requirements.
Therefore, the invention aims to provide instant tartary buckwheat nutritional powder which comprises 30-50% of tartary buckwheat activated powder, 1-5% of konjac refined powder, 1-5% of isomaltooligosaccharide, 5-20% of low PI resistant dextrin and 5-10% of non-nutritive sweetener in percentage by weight; the tartary buckwheat activation powder is obtained by carrying out steel grinding-high pressure cooking treatment on tartary buckwheat.
The mechanical acting force generated by the steel grinding treatment enables the tartary buckwheat cells to be broken, the nutritional components in the tartary buckwheat are dissolved out, meanwhile, the broken granularity of the tartary buckwheat grains processed by the steel grinding is lower than the superfine grinding granularity, if the granularity is too small, tartary buckwheat starch in tartary buckwheat powder is dissolved in hot water and is easy to be pasted, and the solubility is poor, so that the eating of the product is influenced. High-pressure cooking makes nutrition macromolecular substance obtain modifying, increases its solubility, and high-pressure cooking can passivate rutin degrading enzyme simultaneously, avoids active substance rutin in the bitter buckwheat to take place the degradation, and the pressure of high-pressure release for the specific surface area of bitter buckwheat powder increases, has increased the area of contact with the hydrone, and then improves its dissolving speed.
The refined rhizoma Amorphophalli powder is rich in konjac glucomannan, and can not be digested by human body after being eaten, and can inhibit intestinal absorption of cholesterol and bile acid. Glucomannan can form a film that surrounds food after it enters the intestines and stomach, thereby preventing digestive enzymes from interacting with the food, thereby cleansing the intestines and reducing caloric intake.
The resistant dextrin can be used as a stabilizer to further improve the stability of the resistant dextrin, and the purity of the resistant dextrin contains a small part of small molecular monosaccharides, so that modification and separation are convenient. Therefore, the resistant dextrin with a low PI value can be obtained by purifying the resistant dextrin, so that the stabilizing effect can be improved, the saccharides in the resistant dextrin can be reduced, and the resistant dextrin with a low PI value can be used as a stabilizer to be applied to low-sugar products. PI is called the polydispersity index of starch, and the polydispersity index refers to the heterogeneity of molecular weight of starch and can be used to characterize the degree of polydispersity of starch. The closer the PI is to 1, the narrower the molecular weight distribution of the starch system and the more uniform the molecular size. Because the polydispersity of the maltodextrin is large, the maltodextrin is difficult to separate and purify, and the resistant dextrin has high purity and low content of micromolecule sugar, therefore, the maltodextrin is simple and easy to separate and purify and is convenient to operate.
The sucrose fatty acid ester has certain hydrophilicity and water solubility, is used as a food additive, has strong chelating force and is easy to disperse uniformly, is an excellent emulsifier and solubilizer, and can reduce the interfacial tension of macromolecular substances in the tartary buckwheat powder by compounding the sucrose fatty acid ester and the resistant dextrin so as to improve the solubility and stability of the product.
The beneficial effects of the invention are as follows:
(1) the tartary buckwheat is subjected to steel grinding-high pressure cooking treatment to obtain tartary buckwheat activated powder with large specific surface area and strong water absorption, the nutritional value of the tartary buckwheat is improved, and the formed product has high dissolution speed and high dispersion degree;
(2) the low PI resistant dextrin with low sugar content is adopted, so that the hygroscopicity of the product is reduced, and the stability of the aqueous solution of the product is kept;
(3) the non-nutritive sweetener is adopted, so that the food is suitable for people with low sugar intake requirements.
