Abstract: Four preservatives with better preservation effects on Lentinus edodes were chosen from six natural and safe preservatives,namely L-cysteine,NaCl,citric acid(CA),vitamin C(VC),chitosan and phytic acid by single-factor test. Their optimal proportions are L-Cys 2.5 g/L,CA 8.0 g/L,VC 0.5 g/L and NaCl 6% by L9(34) orthogonal test. The complex preservative can extend the shelf life of L. edodes for 15 to 16 d at 10 ℃. This treatment can efficiently decrease the respiration rate,weight lose rate and cell membrane permeability of Lentinus edodes. Compared with the treatment of single-factor preservative or distilled water,the complex preservative has the best preservation effect on Lentinus edodes.
