Embodiment 1
[0023] like figure 1 As shown, a modified atmosphere fresh-keeping method for fresh-cut green peppers, the pre-cooled fresh-cut green peppers are placed in a packaging container, the relative humidity in the packaging container is 95 ± 4%, the temperature is 0-4 ° C, and The mixed gas of oxygen, carbon dioxide and nitrogen is passed into the packaging container, so that the concentration of nitrogen in the packaging container is 85-95%, the concentration of oxygen is 1-8%, and the concentration of carbon dioxide is 1-6%.
[0024] The fresh-cut green peppers include shredded green peppers, sliced green peppers, diced green peppers and chunks of green peppers.
[0025] The fresh-cut green peppers are sterilized by an aqueous solution of chlorine dioxide at a concentration of 100 mg / l for 10-20 minutes before precooling. Sterilization with chlorine dioxide aqueous solution (100mg / l) reduces the total number of initial bacteria and can effectively control the scale of bacterial...
Embodiment 2
[0031] Embodiment two: a kind of modified atmosphere fresh-keeping method of fresh-cut green pepper,
[0032] like figure 1 shown, including the following steps:
[0033] 1. Sorting of green peppers: When sorting green peppers, remove those green peppers that are mechanically damaged, spoiled, germinated, etc. that are not suitable for consumption.
[0034] 2. Peeling and cleaning: Use an automatic green pepper peeling machine to peel the sorted green peppers.
[0035] 3. Cutting: use the automatic green pepper cutting machine to cut the peeled green pepper into shreds, blocks, cubes, slices and other shapes.
[0036] 4. Sterilization: The sterilization method for fresh-cut green peppers (shredded, block, diced, sliced, etc.) is sterilized by chlorine dioxide aqueous solution at a concentration of 100mg / l for 10-20 minutes.
[0037] 5. Rinsing: Use sterile purified water to rinse the sterilized fresh-cut green peppers (shredded, block, diced, sliced, etc.), while controllin...
