The invention discloses a composite
plant source and functional
sugar powder composition for assisting in reducing
blood sugar. The composition is prepared from the following raw materials in parts by weight: 5 to 10 parts of
stevia rebaudiana polyphenol, 8 to 15 parts of angelica keiskei extract, 10 to 20 parts of
aronia melanocarpa fruit extract, 15 to 25 parts of
lithocarpus litseifolius extract, 3 to 8 parts of
tagatose, 15 to 20 parts of oat beta-
glucan, 20 to 30 parts of resistant
dextrin, 2 to 5 parts of L-
arabinose, 50 to 100 parts of a
drying aid, 1 to 3 parts of a flow aid and 2 to 5 parts of a stabilizer. The
powder is prepared through targeted extraction
process optimization (55%
ethanol aqueous solution extraction of
stevia rebaudiana polyphenol, ultrasonic-assisted
water extraction of angelica keiskei, acidic
ethanol extraction of
aronia melanocarpa fruits and composite enzymolysis-membrane separation of
lithocarpus litseifolius) and low-temperature
spray drying, and the
retention rate of active ingredients is greater than or equal to 92%; experiments show that the
powder can enable the blood glucose reduction amplitude of high-glucose diet mice to reach 38%-46% within 2 h after
meal, the
dissolution speed is smaller than or equal to 30 s, and the powder is free of
gastrointestinal tract side effects and suitable for being brewed and drunk by people with hyperglycemia or added into food to serve as a health care product for assisting in reducing blood glucose.
