Selenium-enriched Polygonatum full powder and preparation method thereof

Abstract

The present invention relates to selenium-enriched rhizoma polygonati full powder and a preparation method thereof. The selenium-enriched rhizoma polygonati full powder contains 60-80% of rhizoma polygonati and 20-40% of maltodextrin. A processing method of the selenium-enriched rhizoma polygonati full powder is as follows: the selenium-enriched rhizoma polygonati in selenium-enriched production places is washed and impurities are removed, the impurity removed rhizoma polygonati is soaked by using a rhizoma polygonati peeling agent, and the soaked rhizoma polygonati is peeled by using nylon rolling brushers; after the peeling, citric acid solution is used to wash and neutralize surface residual alkaline liquor; the peeled selenium enriched rhizoma polygonati is subjected to treatment at a high temperature of 105-115 DEG C and under a high pressure for 90-180 min; the processed selenium-enriched rhizoma polygonati is beat into slurry and then the slurry is subjected to high-temperature saccharifying enzyme enzymolysis; a certain amount of a drying aid (the maltodextrin) is added into the enzymolyzed selenium-rich rhizoma polygonati homogenate, and the mixture is homogenized by using a colloid mill; and after the homogenization, the rhizoma polygonati homogenate is subjected to spray drying to obtain the selenium-enriched rhizoma polygonati full powder. The obtained products are light yellow powdery solid, have a certain water solubility, are rich in organic selenium, rhizoma polygonati polysaccharides and other functional ingredients, and have the characteristics of being simple in consumption, high in functional ingredient content, etc., and the preparation method is simple in technology, convenient in operation and relatively low in costs.

Description

technical field [0001] The invention belongs to the field of food processing, and relates to selenium-enriched yellow essence whole powder and a preparation method thereof. Background technique [0002] Rhizoma polygonati (Rhizoma polygonati) is the dried rhizome of the perennial herb Polygonatum Mill. in the Liliaceae family (Liliaeea). Polygonatum contains starch, protein, vitamins, amino acids and trace elements, as well as steroidal saponins, polysaccharides, anthraquinones, lignans, alkaloids and other physiologically active substances. The ancient book "Bielu of Famous Doctors" records that Polygonatum can "eliminate rheumatism, calm the five internal organs, take a long time to lighten the body, prolong life without hunger", and is one of the commonly used traditional Chinese medicines for anti-aging and health preservation. Enshi Prefecture is rich in selenium resources, and the selenium content of the produced crops and traditional Chinese medicinal materials is ge...

Problems solved by technology

[0003] The traditional processing method of Polygonatum is nine steaming and nine drying, that is, steaming Polygonatum and rice wine together, then drying until the skin becomes dry, then soaking with rice wine and steaming, repeating this 9 times, and it takes as long as one month; then the functional components of Polygonatum Extracted with water, then concentrated into a paste, after packaging, it is Huangjing paste, the loss of functional components is large during the extraction process, and the concentration cost is high

Because Polygonatum is rich in polysaccharides, starch, dietary cellulose and other water-absorbing components, traditional milling and powdering processes cannot produce Polygonatum powder
