Abstract: The results showed as follows: After the fresh vegetable soybean was heating in 92~100℃ water for 80~100 seconds, it kept pod and grain emerald green, lost fat oxidase activity, and tasted nicely with no bean smell. Hence heating in 92~ 100℃ water for 80 seconds, cooling in three 0, 5 and 10℃ water respectively ,then freezed at -18℃,there is no significant difference on the contents of crude protein and fat of dry vegetable soybean between different heating and cooling temperature.

Key words: green soybean, heating, cooling, quality
