Embodiment 1

[0021] Such as figure 1 As shown, a modified atmosphere fresh-keeping method for fresh peaches, the pre-cooled fresh peaches are placed in a packaging container, and a mixed gas of oxygen, carbon dioxide and nitrogen is introduced 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%. Put the packed fresh peaches into the cold storage for refrigeration.

[0022] The freshly eaten peaches are freshly picked eighth-maturity peaches. Screen and remove the damaged and spoiled peach raw materials to prevent mutual influence.

[0023] When the fresh peaches are pre-cooled, the temperature of the pre-cooler is 0-4°C, and the pre-cooling time is greater than or equal to 48 hours.

[0024] When the fresh peaches are pre-cooled, an air sterilization system is configured in the pre-cooler to sterilize with a certain concentration of ozone.

[0025] T...

Embodiment 2

[0027] Embodiment two: a kind of modified atmosphere fresh-keeping method of fresh juicy peaches,

[0028] Such as figure 1 shown, including the following steps:

[0029] 1. Picking: When picking, choose peaches that are about 80% ripe.

[0030] 2. Sorting: Screening and removal of damaged and rotten peaches to prevent mutual influence.

[0031] 3. Pre-cooling: Pre-cooling in time after picking, the temperature of the pre-cooling room is 0-4°C, and the pre-cooling time is more than 48 hours. While preventing cold damage, ensure that the central temperature of the peaches meets the requirements; the temperature of pre-cooling and packaging , The humidity should be kept consistent to prevent condensation.

[0032] 4. Sterilization: The pre-cooler is equipped with an air sterilization system, and a certain concentration of ozone is used for sterilization.

[0033] 5. Modified atmosphere packaging: The pre-cooled peaches are packaged in a modified atmosphere packaging method, ...

Abstract

The invention discloses a modified atmosphere preservation method of fresh honey peaches. Precooled fresh honey peaches are put in a 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 preservation method disclosed by the invention, the problems that honey peaches are extremely difficult to store and the time for preservation is short can be mainly solved, and the refreshing time the honey peaches lasts for as long as 25 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 peaches, which is suitable for freshness preservation of freshly picked peaches. Background technique [0002] Peach is very nutritious, and the peach meat is tender and delicious. It is a nutritious fruit suitable for all ages. According to the inspection by experts from the Municipal Academy of Agricultural Sciences, its main nutrients are rich in vitamin C and a large amount of cellulose, carotene, lycopene, red pigment and various trace elements, such as selenium and zinc, which are needed by the human body. It is obviously higher than other common peaches, and it also contains malic acid, citric acid and other ingredients. Eating two peaches a day can play a role in laxative, lowering blood sugar, lowering blood fat, resisting free radicals, removing dark spots, delaying aging, improving immune function, and can al...
