The invention relates to a green antibacterial and brittle fresh-keeping packaging method for sugar-heart Fuji apples. The steps are as follows: Step 1: fermenting Bacillus natto under the auxiliary action of a corona electric field on a needle plate and obtaining metabolites, which are biological inhibitors Bacterial liquid, spray the biological antibacterial liquid on the surface of sugar heart apple by atomization technology; the second step: use ion crosslinking combined with O/W method to prepare essential oil antibacterial and crispy particles, and then spray the essential oil antibacterial and crispy particles On the polymer plasticized packaging film, and then vacuum treatment to achieve the film to tightly wrap the sugar heart Fuji apples; the third step: use PE film to make packaging bags to pack apples, use a single CO 2 gas to inflate the packaging bags, and then Use medium-dose ionizing radiation for irradiation treatment; fourth step: cryogenic storage. The method of the invention can effectively improve the bacteriostatic effect and prolong the preservation time. |
