Abstract

The invention discloses an activated freshness-keeping carton comprising a carbon body and a freshness-keeping agent layer arranged on the inner wall of the carbon body. The freshness-keeping agent layer is composed of, by mass, 25%-40% of a freshness-keeping material and 60%-75% of ink. The freshness-keeping material in the freshness-keeping agent layer has the freshness-keeping function on fruits and vegetables in the packaging carton, especially tropical fruits. The manufacturing technology of the activated freshness-keeping carton is simple, and cost is low. The activated freshness-keeping carton is convenient to use in daily storage or in the transportation process and occupies small space, and common peasant households can purchase the activated freshness-keeping carton. Compared with a traditional refrigeration house and a controlled atmosphere fresh-keeping manner, the activated freshness-keeping carton significantly lowers the storage cost of the fruits, and the storage time of the fruits is effectively prolonged to 1-3 times. The invention further discloses a manufacturing method of the activated freshness-keeping carton. The manufacturing technological process is simple, the manufacturing conditions are gentle, and the activated freshness-keeping carton is suitable for mass industrial production.

Description

technical field [0001] The invention belongs to the technical field of fruit freshness preservation, and relates to a freshness preservation carton, in particular to an active freshness preservation carton for fruits and a preparation method thereof. Background technique [0002] According to statistics, my country loses more than 8 million tons of fruits and vegetables due to rot every year, ranking first in the world, especially for tropical fruits such as kiwi, mango, and banana. If damaged or attacked by pathogens, rot is more likely to occur. These problems make it difficult for these tropical fruits to be stored for a long time and transported over long distances, and the supply range is relatively limited. [0003] In order to reduce the loss rate of fruits and vegetables, various methods have been adopted in the industry to preserve the freshness of fruits and vegetables, mainly including cold storage storage, controlled atmosphere preservation, and chemical reagent p...
