A method for sterilizing and preserving fresh mulberry fruits is provided, relating to the technical field of fruit preservation. The method comprises the following steps: (1) laying fresh mulberry fruits in a single layer in a hermetic container; and (2) introducing atmospheric plasma into the hermetic container for sterilization to obtain sterilized fresh mulberry fruits. The method provided in the present disclosure can effectively inactivate bacteria, yeast and fungi on the surface of the mulberry fruits, such as Botrytis cinerea, Salmonella, Escherichia coli, Staphylococcus aureus and Bacillus cereus. The method provided in the present disclosure has no significant impact on mulberry fruit qualities such as pH, TSS, hardness and color, and can significantly reduce rotting incidence and mildew incidence. The rotting incidence can be reduced by up to 30.00% and the mildew incidence can be reduced by up to 25.14%.
A: Disclosed in the present invention are derivatives of naftifine hydrochloride, and a preparation method and use thereof. The derivatives of naftifine hydrochloride of the present invention have a structure as shown by formula (I), wherein Ar has the definition as described in the description and claims. By inhibiting the expression and/or function of key catalyzing enzyme CrtN in a golden yellow pigment synthesis pathway and powerfully inhibiting the synthesis of golden yellow pigments, the virulence of bacteria can thus be lowered. The key catalyzing enzyme CrtN in the golden yellow pigment synthesis pathway can be used as a drug target; and compounds capable of inhibiting the expression and/or function of the catalyzing enzyme CrtN can be used for preparing anti-bacterial drugs. The naftifine hydrochloride and the derivatives thereof in the present invention can be used as inhibitors for the catalyzing enzyme CrtN to powerfully inhibit the synthesis of golden yellow pigments, so that the virulence of  Staphylococcus aureus  can be lowered, and same can thus be used for preparing the anti-bacterial drug, and especially a drug for resisting  Staphylococcus aureus  infections.
B: A preservation method for fruit transportation, comprising the following steps: an inactivation step, comprising disrupting fruit cells, releasing cell content and stopping cellular bio-metabolism; and a preservation step, comprising freezing a disrupted cell product for ease of transportation. The preservation method and the product thereof release cell content in a novel way by means of inactivation by disrupting fruit cells, thereby obtaining cell content necessary for high quality fruit aroma and texture, and stopping the bio-metabolism of the fruit cells, thereby preventing freezing damage to fruit at low temperatures. Freezing after inactivation can delay and even stop chemical reactions of various components in fruits, preserving freshness without needing to add any additives or preservatives, and also preserving the fresh texture and aroma of fruits for a long time. The product prepared using the preservation method is easy and elegant to use, facilitates transport, has high efficiency and resolves the global issue of fruit transportation and preservation.
C: The present invention relates to the field of disinfectants. Provided in the present invention is a disinfectant composition, which comprises, in percentages by mass: 59-88% of ethanol, 1.5-8% of isopropanol, 0.2-8% of urea, 0.2-6% of an organic acid, 0.1-2% of borneol, 0.1-3% of a zinc salt, and the balance of water. The disinfectant composition provided by the present invention can be applied to the surface disinfection of various inanimate objects, and can also be applied to skin disinfection to effectively play a role in killing Staphylococcus aureus, Escherichia coli, Candida albicans, Pseudomonas aeruginosa, poliovirus, adenoviruses, norovirus, polyomavirus, etc. Strict disinfection requirements are met, and no skin irritation is caused.
D: Disclosed are a method and a device for the deodorization, sterilization and disinfection of a refrigerator, wherein a modified silicon dioxide non-metal nano-material (I) is first purified and then formed into a powder; the powder is then placed on a special electron-generating device (III), and the electron-generating device (III) can continuously generate a large number of positive and negative ions; and meanwhile, the powdery modified silicon dioxide nano-material (I) is mixed with a new environmentally friendly biological preparation material drug (II). In the method, a large number of positive and negative ions are generated by means of the electron-generating device (III), which can not only sterilize and disinfect on its own, but also improve the adsorption strength of the modified silicon dioxide nano-material, and achieve the bi-directional adsorption by positive and negative ions of odors, bacteria, heavy metals and chemicals such as carcinogenic chemicals to the modified silicon dioxide nano-material (I), and the mixed environmentally friendly biological preparation (II) is also capable of killing bacteria and toxins such as Escherichia coli, Candida albicans, Staphylococcus aureus, and Aspergillus niger, and the three work together to have a significant effect in the deodorization, sterilization and disinfection of a refrigerator.
