First, the reason why it is difficult to save:
1. Litchi has the characteristics of strong perishability and poor storage resistance during storage, mainly due to the special physiological structure and chemical composition of litchi, storage conditions and treatment methods.
2. Litchi peel is thin and easy to fall off, which makes the taste and flavor of litchi very good, but it is also easy to cause bacteria, mold and other microorganisms to grow on the peel, which in turn leads to litchi rot.
Second, the influence of chemical composition:
1, litchi contains unsaturated fatty acids and a large number of ester compounds, which are easily reacted by oxidase, releasing harmful substances and causing corruption. In addition, litchi is also rich in sugars and acids, which will promote the growth and reproduction of microorganisms, thus accelerating the process of litchi corruption.
2. Litchi needs a high temperature and high humidity storage environment. However, if the storage environment is too humid, litchi is prone to mildew and deterioration. At the same time, litchi needs ventilation during storage, otherwise too much water in litchi will lead to corruption.
Three. Improper transportation and handling methods:
1. Litchi has short picking time and short storage period. If we don't pay attention to environmental sanitation and temperature control during litchi picking, transportation and treatment, it is easy to produce mildew, maggots and other phenomena, resulting in litchi rot.
2. According to the perishable characteristics of litchi, we can also keep it fresh by processing, such as making litchi into dried litchi or litchi drink, which can effectively prolong the service life of litchi. These measures can effectively reduce the loss of litchi and ensure the healthy development of litchi industry.
Fourth, the preservation method:
1. During picking, transportation and treatment, attention should be paid to environmental sanitation and temperature control to keep litchi fresh, and litchi should be protected with packaging materials to prevent external pollution and microbial invasion.
2. During the storage of litchi, it is necessary to control the temperature and humidity, avoid excessive humidity and high temperature, check the quality of litchi regularly, and deal with problems such as rot, mildew and deterioration in time.
