Snow fungus (
) with functional contents has satisfactory effects on various diseases, including atherosclerosis, high cholesterol, healthy skin, cancer, diabetes, and anti-inflammation. In this study, the extraction yield and functional contents (ergothioneine and
-glucan) of white jelly fungus were compared based on the extraction conditions using response
surface methodology. Results revealed the extraction conditions for optimization
of the dependent variables to be 60
C and 4.33 h, when 16.6 mg/mL of sample concentration was used. Under these conditions, the extraction yield was 24.9%, including ergothioneine (66.8
-glucan (34.9 g/100 g). These results can be useful in understanding the functional ingredients and mass extraction process in mushroom.
