Controlled atmosphere fresh-keeping packaging box for fresh-cut fruits or vegetables

Abstract

The invention discloses a controlled atmosphere fresh-keeping packaging box for fresh-cut fruits or vegetables, and belongs to the field of fruit and vegetable fresh-keeping packaging. The packaging box consists of three parts, specifically, a box cover, a storage box and a water storage box, wherein a controlled atmosphere hole and a groove with a cover are formed in the box cover, draining through holes are formed in the bottom surface of the storage box, a preservative storage cavity is formed in the vertical direction, and fresh-keeping vent holes are formed in the surface of the preservative storage cavity. According to the packaging box, the gas environment in the box is effectively controlled through the controlled atmosphere hole in the box cover, so that the quality of the fruit and vegetable is reduced caused by excessive anaerobic respiration is avoided, the bottom of the box is connected to the detachable preservative storage cavity, the preservative agent gas is uniformlyreleased through through holes in four walls of the cavity to inhibit the physiological activity and mildew rot of the fresh-cut fruits and vegetables, and a box body is arranged to store water so asto keep certain humidity in the box, and the shelf life of the fresh-cut fruits and vegetables is prolonged.

Description

technical field [0001] The invention relates to a modified atmosphere fresh-keeping packaging box for fresh-cut fruits and vegetables, belonging to the field of fresh-keeping packaging for fruits and vegetables. Background technique [0002] Fresh-cut fruits and vegetables, also known as minimally processed fruits and vegetables, refer to the use of fresh fruits as raw materials, after grading, cleaning, trimming, peeling, cutting, fresh-keeping, packaging and other treatments, and then transported at low temperature into the Ready-to-eat fruit and vegetable products sold in refrigerators. Fresh-cut fruits and vegetables have been widely favored by people because of their natural, nutritious, fresh, convenient and high availability. However, due to mechanical cutting, the respiration intensity of fresh fruits and vegetables will be significantly increased and browning will occur, which will be easily attacked by microorganisms to cause corruption, damage the quality and red...

AI Technical Summary

Problems solved by technology

However, due to mechanical cutting, the respiration intensity of fresh fruits and vegetables will be significantly increased and browning will occur, which will be easily attacked by microorganisms and cause corruption, damage the quality and reduce the nutritional value.

Although there are many preservation methods for fresh-cut fruits and vegetables in China, most of them are preserved by adding chemical additives, and fresh-cut fruits and vegetables are kept fresh without the use of chemical additives. The products that mainly use packaging to transport and store fresh-cut fruits and vegetables and extend the shelf life are relatively rare.
