Description

A portable strawberry freshness detection box and strawberry storage box

technical field

The invention relates to the field of strawberry packaging, in particular to a portable strawberry freshness detection box and a strawberry storage box.

Background technique

Strawberries have high nutritional value, contain a variety of nutrients, and have health benefits. After harvesting, strawberries need to be put into packing boxes for storage and transportation. However, strawberry pulp is soft and juicy, with high water content, delicate tissue, no skin protection, and is vulnerable to mechanical damage. Especially strawberry is a class of aggregate fruit, the main edible part is the enlarged receptacle, and the cuticle of epidermal cells on the surface of the enlarged receptacle is very thin, which is most susceptible to mechanical damage. So strawberry is a kind of fruit that is vulnerable to mechanical injury. Especially in the transportation process after picking, it is extremely vulnerable to damage and deterioration due to mechanical vibration of vehicles. On the other hand, after harvesting, strawberries breathe vigorously, consume a lot of internal nutrients, and are easily infected by microorganisms such as gray mold, rhizopus, and skin rot bacteria, and are prone to rot and deterioration. Whether it is mechanical damage or post-harvest senescence and rot, the quality of strawberries will be seriously affected, resulting in a large amount of economic losses.

Strawberries are stored in packing boxes during cold chain logistics transportation and cold storage storage. The storage environment is airtight and dark. It is difficult to assess the degree of mechanical damage by visual observation or camera image detection. However, the volatile substances released by strawberries will change after they are mechanically damaged or senile and rotted. Therefore, by detecting the volatile substances of strawberries, it can be judged whether strawberries have rotted or suffered mechanical damage during storage or transportation, thereby affecting the letterboxiness of strawberries. At present, there is a lack of a detection method and a detection box that can collect in real time the volatile substances of strawberries stored in the transport box, thereby effectively detecting the freshness of strawberries in the box.
