The presence of hickory and black soybean had no significant
effect on the total count of lactic acid bacteria of the HBY (p > 0.05),
but improved the WHC and decreased the STS of the yogurt.
Texture, amino acids and protein content of yogurt had been
improved by adding hickory-black soybean milk. HBY also exhibited
higher antioxidant activity than CMY. HBY can be promoted in
the dairy market as the higher nutrition and stronger antioxidant
activity of this yogurt, and it also will be favored by more
consumers. The antioxidant mechanism of HBY will have been
studied in the future work.
