| Abstract: | Objective: To find a method for dehydration of GB - penicillin mushroom dregs and determine the contents of saccharides in dregs. Methods: The water in mushroom dregs was dehydrated with a variety of salt. Dehydration quality of these methods was compared, were contents of water- soluble saccharirides in dregs were determined by phenol - H2SO4 method using UV-751 at 490nm. Results: NaCl and CaO were bett'er as dehydrating substance. The contents of water - soluble sacchrides in dregs was 0.5%. Conclusion: Dehydration of GB - penicillin mushroom dregs could be conducted smoothly by selecting appropriate salt. |
