Abstract:

Soybean and ginger were used as main materials to develop ginger flavored soymilk. The production process of ginger flavored soymilk was investigated by single factor and orthogonal array methods. Results showed that the optimal formula of ginger flavored soymilk made from soybean slurry with a material/water ratio of 1:7 (m/m) consisted of ginger juice 8.0%, cane sugar 9.0%, milk powder 5.0%, carrageenan 0.01% (mass fraction), and xanthan gum 0.02 g/100 g. The optimal values of pH, temperature and temperature-holding time for obtaining an optimal coagulation were determined to be 6.2, 60 ℃ and 5 min, respectively. Processed soymilk under the above conditions showed good gel strength and refreshing taste and no soybean odor was smelled.

Key words: ginger, soymilk, coagulation, formulation, production process
