Abstract: A fruit sterilizing and cooling device using a plasma-activated ice-water mixture includes a top-opened tank body, where the tank body includes a front side provided with an ice-water tank, and a rear side provided with a cooling tank; a clapboard is provided between the ice-water tank and the cooling tank; a water passing port is formed in an upper portion of the clapboard; a grid plate is inserted at the water passing port; ice cubes are added to an upper portion of the ice-water tank; one side of a lower portion of the ice-water tank is connected to a plasma-activated water (PAW) generator; a valve is provided at a water outlet of the PAW generator; a fixed fence frame and a movable fence frame are provided in the cooling tank; and fruits to be treated are placed in the movable fence frame.

Abstract: A method for simultaneously separating and purifying myricetin-3-O-(2?-O-galloyl)-a-L-rhamnoside and myricetin-3-O-(4?-O-galloyl)-a-L-rhamnoside from Bayberry leaves, and the use of the compounds prepared by the method. The method includes: (1) alcohol extraction and concentration: mixing Bayberry leaves with an alcohol solution; (2) solid-phase extraction column adsorption: injecting the crude Bayberry leaf flavonol alcohol extract into a solid-phase extraction column; washing with a mobile phase for the first gradient elution; (3) preparative liquid chromatography purification: using a solid-phase chromatography column; wherein the solid-phase extraction powder obtained from step (2) is subjected to a second gradient elution with a mobile phase and then processed to obtain the target products: myricetin-3-O-(2?-galloyl)-?-L-rhamnoside monomer and myricetin-3-O-(4?-galloyl)-?-L-rhamnoside monomer.

Abstract: Embodiments of the present disclosure provide a method for reduced-medicine treatment for post-harvest preservation of bayberries. The method includes: (1) packing after picking: placing ripe bayberries into a skeletonized injection-molded package after picking, the bayberries being spaced apart and evenly arranged in the skeletonized injection-molded package; (2) low-concentration peroxyacetic acid solution treatment: spraying a peroxyacetic acid solution with a concentration of 0.1% onto a surface of the bayberries; and (3) atmospheric plasma treatment: performing an atmospheric plasma treatment on the bayberries treated with the peroxyacetic acid solution for 5 minutes, and temporarily storing the bayberries in a refrigerated warehouse at 4° C. after the treatment. By combining peroxyacetic acid with atmospheric plasma, an amount of peroxyacetic acid solution used can be effectively reduced and efficacy of the treatment can be increased.

Abstract: A method for guiding a sales strategy of loquat fruits by evaluating and predicting quality of the loquat fruits is provided. The method slices and stains an equatorial plane of an loquat fruit and calculates a lignified cell density P of the equatorial plane of the loquat fruit, so as to guide a current price of a batch of loquat fruits. The current price of the loquat fruits increases as P decreases. The method analyzes a growth stage of the lignified cells and predicts a quality change trend value T of the batch of loquat fruits, so as to guide a storage strategy based on T. The loquat fruits are suitable for storage and transportation when T is high, and the loquat fruits need to be sold as soon as possible when T is low.
