Factors affecting the preservation of fruits and vegetables:  

The factors that affect the metabolic activity and storage effect of fruits are mainly divided into two categories: external factors and factors of the fruit itself. The main external factors are temperature, gas composition and humidity. Low temperature can inhibit fruit respiration and other metabolic processes, thereby delaying aging. Under the premise of no chilling injury, the lowest possible temperature should be used to extend the storage period; gas supermarkets store vegetables and fruits

The components also have an important effect on the preservation of fruits, changing the gas composition in the surrounding environment, such as reducing the oxygen content, increasing the carbon dioxide content can slow down the metabolism, and can extend the fruit storage time; the process of harvesting the fruit to absorb water from the roots of the plant is terminated. It can cause changes in structure, texture and surface, so maintaining a certain humidity and reducing water loss also play a key role in maintaining the freshness and quality of fruits! In order to reduce the impact of humidity on the preservation of fruits and vegetables, ultrasonic humidifiers are used in various large supermarkets to keep fruits and vegetables fresh and humidify, reduce water loss and maintain the color quality of fruits and vegetables.

The brand NAISIDA of Guangdong Aoyu Electrical Appliance Co., Ltd. mainly develops and sells "household dehumidifiers, commercial dehumidifiers, industrial dehumidifiers, fresh air purifying dehumidifiers, cooling dehumidifiers, temperature regulating dehumidifiers," with constant temperature and humidity products. Constant temperature and humidity machine, rotary dehumidifier, ultrasonic humidifier, wet film humidifier and non-standard product development".
