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 application discloses use of Bacteroides thetaiotaomicron in preparation of products for reducing cold stress response of ruminants. It is found that feeding Bacteroides thetaiotaomicron to ruminants, especially young calves, can effectively reduce the cold stress response of the ruminants.
