technical field

[0001] The invention relates to the technical field of fruit and vegetable storage and preservation, in particular to a grape preservation paper and a preparation method thereof. Background technique

[0002] The postharvest loss of fruits and vegetables in our country is huge. According to rough estimates, the postharvest loss rate of fruits is 20% to 25%, and the postharvest loss rate of vegetables is 25% to 30%. If calculated according to the current production level, only the annual loss of vegetables Just over 100 million tons, and the value of fruit and vegetable losses amounted to hundreds of billions of yuan. Therefore, it is of great significance to effectively prolong and maintain the postharvest commercial quality of fruits and vegetables. Affected by the level of development, at present, the preservation of agricultural products in my country mainly adopts the method of refrigeration + MAP + preservatives, that is, combined with low-temperature f...
