The cantharellus cibarius freezing technics was studied through analyzing the freezing curve at different temperature,freezing speed and juice leakage by liquid nitrogen flash freezer.The results showed that there were obvious three freezing stages by freezing in -60℃,but the three freezing stages were not obvious by liquid nitrogen flash freezer in other temperature.The author proposed that freeze this mushrooms under -80℃,frozen food were stored 6 months at (-26℃,)its juice leakage less than 2.7% after thawing.
