The invention discloses a dodecenyl succinic anhydride starch nanocrystal, a preparation method for preparing an active thin film solution by using the starch nanocrystal and application of the starch nanocrystal to fruit preservation, and the method comprises the following steps: after preparing the starch nanocrystal into a suspension, adding a dodecenyl succinic anhydride (DDSA) ethanol solution to carry out esterification reaction; in the esterification reaction process, normal pressure plasma jet (APPJ) treatment is carried out at the same time, the pH is kept between 8.5 and 9.5 in the whole reaction process, and after the reaction is finished, centrifugation, washing and freeze drying are carried out to obtain the dodecenyl succinic anhydride starch nanocrystal. According to the method, through DDSA esterification and APPJ cooperative treatment, the substitution degree of the DDSA to the SNC can be improved, the critical aggregation concentration of the DDSA-SNC is reduced, and the WCA (water contact angle) is improved. Thymol Pickering emulsion is stabilized through the prepared dodecenyl succinic anhydride starch nanocrystals, and the emulsion is mixed with starch gelatinization liquid, so that thymol is encapsulated in starch film liquid. The prepared composite membrane liquid can well prolong the preservation time of the Zaosu pears.

The invention provides a method for preserving cherry tomatoes through combination of a low-voltage electrostatic field and modified atmosphere packaging and application of the method, and belongs to the technical field of preservation. The method comprises the following steps: pre-cooling cherry tomatoes, packaging the cherry tomatoes with a modified atmosphere packaging material, treating the cherry tomatoes in a low-voltage electrostatic field after packaging, and storing the cherry tomatoes. The low-voltage electrostatic field treatment is combined with the packaging treatment, so that the respiration rate can be reduced, and the gas environment in the package can be changed, thereby reducing the consumption of nutrient substances caused by respiration, improving the capability of cherry tomatoes for removing active oxygen, inhibiting membrane lipid peroxidation, reducing the accumulation of malondialdehyde, enhancing the antioxidant level and delaying the maturation and aging of the picked cherry tomatoes; the fresh quality of the cherry tomatoes is effectively maintained.

The application belongs to the technical field of food preservation, and specifically discloses a kind of postharvest high-voltage alternating electric field and low-temperature synergistic storage preservation method of fresh lotus seeds, comprising the following steps: S1, fresh lotus seed pretreatment, get shelled fresh lotus seed;S2, the shelled fresh lotus seed obtained in S1 is placed in a constant low-temperature incubator with high-voltage alternating electric field for storage preservation.The application adopts the above-mentioned postharvest high-voltage alternating electric field and low-temperature synergistic storage preservation method of fresh lotus seeds, for the first time, high-voltage alternating electric field is applied to the storage preservation of fresh lotus seeds, effectively slows down the metabolism and aging process of lotus, also can reduce the loss of nutrients, the preservation effect is good, and the safety is high, no residue, small harm.This method is simple to implement, cost-effective, and friendly to the environment, has a wide application prospect and market potential.
