Description
Technical Field
The invention belongs to the field of food processing, and relates to selenium-rich polygonatum sibiricum whole powder and a preparation method thereof.
Background
Rhizoma Polygonati (Rhizoma Polygonatum) is dried rhizome of Polygonatum sibiricum of Polygonatum of Liliaceae (Liliaaeea), is a traditional medicinal and edible plant material with homology, and is also a plant resource special in Wuling mountain area. Rhizoma Polygonati contains starch, protein, vitamins, amino acids, microelements, and multiple physiologically active substances such as steroid saponin, polysaccharides, anthraquinone, lignanoid, and alkaloid. According to records of ancient books of famous physicians and others, polygonatum sibiricum can remove rheumatism, calm five internal organs, lighten body after long-term taking, prolong life and avoid hunger, and is one of the commonly used traditional Chinese medicines for resisting aging and preserving health. The selenium resource of Enshi is abundant, and the selenium content of the produced crops, traditional Chinese medicinal materials and the like is generally higher. Through determination, the selenium content in wild rhizoma polygonati tubers in Enshi Bifeng, Xuan En and the like reaches 0.4-0.8mg/kg, is 8-20 times of the selenium content in rhizoma polygonati tubers in other areas, and reaches the standard of selenium enrichment.
The traditional rhizoma polygonati processing method is nine times of steaming and nine times of drying in the sun, namely, the rhizoma polygonati and yellow wine are steamed together, then the rhizoma polygonati and the yellow wine are dried in the sun until the epidermis becomes dry, then the rhizoma polygonati and the yellow wine are soaked and then steamed, the steps are repeated for 9 times, and the consumed time is as long as about 1 month; and extracting rhizoma Polygonati functional components with water, concentrating into paste, and packaging to obtain rhizoma Polygonati paste, with high loss of functional components and high concentration cost. Because rhizoma polygonati is rich in polysaccharide, starch, dietary cellulose and other water-absorbing components, the traditional grinding process, the powdering process and the like can not prepare the rhizoma polygonati powder.
CN103931861A discloses a processing technology of selenium-rich polygonatum sibiricum preserved fruit, which sequentially comprises the steps of selecting materials, cleaning, rehydrating, dicing, soaking, blanching, sugar soaking, drying and packaging, wherein the sugar soaking treatment comprises the steps of adding clear water into mannitol to be placed in a boiling pot, preparing sweet solution, adding citric acid, heating until the mannitol is completely dissolved, adding the blanched polygonatum sibiricum dices, boiling until the polygonatum sibiricum dices are uniform, and taking out when the polygonatum sibiricum dices are sweet and sour, and putting the polygonatum sibiricum dices into a heat-preservation barrel for heat preservation. CN 105349356A discloses a method for preparing a fresh bamboo wine containing selenium-rich rhizoma Polygonati, which comprises soaking fresh selenium-rich rhizoma Polygonati in a white spirit jar of 52 degree in proportion for one year to obtain selenium-rich rhizoma Polygonati wine; selecting more than 2 years old moso bamboos without scabs and green mottles 10 days after the Qingming festival, selecting a bamboo joint section 1-2 m away from the ground, injecting selenium-rich yellow wine, allowing the bamboo joint section to grow, and taking out the moso bamboos after one year.
