Abstract:

The endosperm and plumule of germinating tartary buckwheat seeds were stripped and analyzed for distribution
and change of various nutrients such as moisture, crude protein, starch, α-amylase activity, β-amylase activity, reducing
sugar and total flavonoid. Based on an overall consideration of all the nutrients, the optimal germination time for tartary
buckwheat pulping was 5 days. Using one-factor-at-a-time and orthogonal array designs, the optimal pulping parameters
were determined as 1:4 (g/mL), 7, 50 ℃ and 3 min for material/liquid ratio, pH, temperature and time, respectively. The
utilization of raw material was 73.38% and the total flavonoid content was 25.59 mg/100 mL.

Key words: tararty buckwheat, germination, nutrient substance, change and distribution, extraction
