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...

Abstract

The invention discloses a modified atmosphere preservation method of fresh-cut green pepper. Precooled fresh-cut green pepper is put in a packaging container; the relative humidity is 91-99% and the temperature is 0 to 4 DEG C in the packaging container; mixed gas of oxygen, carbon dioxide and nitrogen is introduced into the packaging container until the concentration of nitrogen, oxygen and carbon dioxide is 85-95%, 1-8% and 1-6% respectively. According to the method disclosed by the invention, fresh-cut green pepper (the shredded pepper or the diced pepper and the like) is extremely easy to oxidize and discolor to keep the freshness and the unchanged color in 10 days.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and relates to a modified atmosphere preservation method for fresh-cut green peppers. The fresh-cut green peppers include shredded green peppers, sliced ​​green peppers, chunks of green peppers, diced green peppers and the like. Background technique [0002] In recent years, with the acceleration of the pace of urban life, changes in the living and consumption habits of urban people and the improvement of consumption levels, convenient, fast, safe and pollution-free clean vegetables are becoming more and more popular among consumers as a fashionable consumer product; at the same time Consumers have higher and higher requirements for the freshness of clean vegetables. Coupled with the national agricultural departments at all levels paying attention to how to reduce the loss of agricultural products and the advancement of the convenience project of vegetable baskets, and the health depart...
