Soybeans (10 g) were washed three times using tap water one time rinsing using de-ionized water followed by soaking in deionized water (1 L) for 14 h at room temperature (Wang, Yu,
Yang, & Chou, 2003). Excess water was then drained off and the
shells were removed. The swollen beans were blended with 250 mL
of boiling water in a laboratory blender (Waring, New Hartford, CT,
USA) at low speed followed by boiling for 5 min. The blended
soybean was then passed through 4 layers of cheesecloth. The soy
milk fat content (1.86%) was corrected to 3.4% using 1.54 g soy oil/
100 g soy milk. The soy milk was reheated to 80 C for 10 min and
immediately chilled (4 C) prior to making ice cream.
