The preservation method comprises the steps of firstly, carrying out sealed fumigation on the cold-sensitive fruits and vegetables for 12 hours by jasmonic acid methyl ester at room temperature, soaking and carrying out cold shock on the fruits and vegetables for 1 hour in the ice water mixed solution, taking out the fruits and vegetables and airing the surface water. The cold-resistant preservative does not generate obvious symptoms of chilling injury after being placed for two weeks in an environment at 0-4 DEG C; corruption mildew and quality drop of the fruits and vegetables stored in the environment at room temperature and proper low temperature can be effectively restrained; and the refreshing time is obviously prolonged.

Preparation method for selenium-rich astaxanthin chlorella powder
The invention discloses a preparation method for selenium-rich astaxanthin chlorella powder. The method comprises the following steps: selecting fine chlorella strain bred with ultraviolet ray and performing irradiation mutagenic treatment, thereby acquiring a fine new strain; culturing in a creative optimized BG11 culture medium; using a series of parallel 40.0W red light tubes and 1.2m long 28.0W blue light tubes for irradiating the chlorella liquid, continuously culturing till reaching the logarithmic phase and determining D600nm; inducing the chlorella to generate selenium-rich protein; adopting 1.2m long blue light tubes, high luminous intensity, nitrogen starvation, 51.8g / L glucose and 20.0g / L xylose for performing biomass fermentation and inducing a part of astaxanthin; increasing the illumination intensity in steps in a wide inducing stage; adopting jasmonic acid methyl ester, salicylic acid and ethephon for inducing, thereby acquiring astaxanthin selenium chlorella strain; lastly, adopting a creative combined enzymic method and the optimized high-pressure homogeneous wall breaking for acquiring the chlorella powder and adopting novel shrimp head endogenous enzyme for assisting in extracting astaxanthin.
