Some indexs were assayed during cold storage. The results suggested that this treatment can sustain the content of soluble solid substance, VC and titratable acid and cut down the weight loss. The microbial growth of treated fruit is inhibited, so the decay of treated strawberry is much less than the control, and shelf life is prolonged.
