It was showed that high CO2 treatment was a positive way to control .

An ethanol-resistant and heat-resistant mutant (UV-7-36-12-17) of Saccharomyces cerevisiea was successfully bred by the techniques of UVB radiation culture and heat-shock treatment,which could grow well in the triangular flask under the conditions of 16 %(v/v)ethanol content,temperature at 36 ℃,and alcohol content reached 14.

Rigor mortis , ageing, tenderization mechanism,pulsed electrical current-termed electrical stimulation, calcium chloride processing, exotic proteinase processing, stretching techniques , pH control processing, high pressure process, hydrodynamic shock waves process etc.

Through comparing the variations of their contents after different cold shock treatments and the chilling injuries (CI), the regularity of phytohormone variations and the relationship between phytohormones level and the chilling tolerance of Nai-plum fruits during the cold storage were discussed.

The results showed that cold shock treatment refrained desiccation, and the degree of refrainment was increasing with the duration of cold shock treatment.

The experiment showed that cold shock treat-ment refrained the activity of polygalacturonase,and the degree of refrainment was increasingwith the time of cold shock treatment.
