Abstract

The invention provides a preparation method of selenium-enriched brown sugar, which comprises the following steps of: S1, peeling sugarcane, cutting the sugarcane into sections, juicing, filtering juice, adding sucrase and maltase, adjusting conditions for enzymolysis, adjusting conditions, adding selenium-enriched yeast, and performing enzymolysis, enzyme deactivation, filtration and concentration to obtain concentrated sugarcane juice; S2, boiling the concentrated sugarcane juice at 150-190 DEG C for 30-50 minutes, adding brown granulated sugar, stirring for dissolving, boiling at 190-220 DEG C for 60-100 minutes, adding stevioside, stirring for dissolving, boiling at 220-270 DEG C for 30-60 minutes, and cooling to 100-120 DEG C; and S3, spreading the boiled liquid on a cold bed, neatly scribing the liquid by using a scribing tool, and packaging and selling the liquid after the liquid is completely cooled and formed. The selenium-enriched yeast is added, so that the brown sugar is more fragrant and sweet in taste and rich in selenium element, and the health-care effect is broadened.

Description

technical field [0001] The invention relates to the technical field of brown sugar processing, in particular to a selenium-enriched brown sugar and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for the human body, which can improve human immunity, and has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers. Its intermediate metabolite methyl enol in the body It has strong anti-cancer activity, and at the same time has the effect of reducing and alleviating the toxicity of heavy metals. Selenium in the human body is mainly obtained from daily diet, and the content of selenium in food directly affects people's daily selenium intake. The lack of selenium can lead to Keshan disease, Kaschin-Beck disease, cancer, cardiovascular disease, cataract, cystic fibrosis, hypertension, goiter, immunodeficiency, lymphoblastic anemia, retinal spot degeneration, muscle Mal...
