Abstract:
A kind of nutrient was made from black soybean and black sesame through extruding, blending and grinding. Its nutrient components were determined with the national standards. Kunming mice were used to evaluate the anti-fatigue activities of the black soybean nutrient (black soybean nutrient was added in the feed) with different dosages(15, 30, 45 g/kg?bw) for 45 days, by measuring the swimming time, serum urea, hepatic glycogen and blood lactic acid. The results showed that the nutrient was in accordance with FAO/WHO high quality protein pattern. Amino acid score(AAS)，chemical score(CS) and essential amino acid index(EAAI) of the black soybean nutrient was 1.02，0.65 and 78.77, respectively. Black health nutrition paste increased the swimming time of the mice and promote the level of their hepatic glycogen. In addition, the nutrient decreased the serum urea content and the area under the curve of blood lactic acid. The optimal dosage of nutrition paste was 30g/kg?bw．This research showed that the black soybean nutrient was a good protein supplement with alleviating fatigue function.
