China is a big agricultural country with a large population, and its fruit and vegetable production and food industry are developing rapidly. However, due to the high demand for time and space in agricultural products logistics, agricultural products are produced seasonally, consumed all year round, produced regionally and consumed nationwide; The related technologies of product preservation, storage and transportation are kept in boudoir, so it is difficult to enter the gate of the farm, which leads to the gap between food hygiene indicators and international norms, and food safety often does not meet the hygiene requirements.

1, the transportation rate of food in cold storage is low.

At present, the demand for cold chain logistics in China is huge, but as far as the overall cold chain system is concerned, the food cold chain in China has not yet formed a system, and the hardware facilities of the food cold chain are far behind. No matter from the domestic consumption demand of China's economic development, or compared with developed countries, the gap is very obvious.

2. There are few third-party logistics services.

China is in the initial stage of transforming from traditional logistics service to modern logistics socialization. The cold and fresh food circulation service has just started in China, and the proportion of logistics enterprises that can provide full-service is very small.

3. The cold chain operation management is not standardized.

Professional cold chain logistics has quite strict standards. Delivery must be classified and loaded, and the temperature should be adjusted according to different goods. There are also monitoring and temperature records throughout the transportation.

(2) China's cold chain logistics faces problems such as insufficient facilities and equipment, lack of technical standards and imperfect industrial support.

The development of cold chain industry in China needs to break through three major constraints:

1, insufficient facilities and equipment.

At present, China's cold chain facilities and cold chain equipment are insufficient, and there are too many debts in the construction of hardware facilities. The original facilities and equipment are outdated and uneven in development and distribution. They are mainly distributed in the main fruit and vegetable producing areas and vegetable bases in the suburbs of large and medium-sized cities, as well as in the cold storage of large and medium-sized cities to meet the government's task of storing frozen meat, and can not systematically provide effective low-temperature protection for the circulation of perishable foods.

2. Lack of technical standards

Because the food cold chain is a supply chain system with the aim of ensuring the quality of perishable food and the core requirement of maintaining a low temperature environment, it is more demanding and complicated than the general normal temperature logistics system, and the construction investment is much larger.

3. Incomplete industrial support.

The timeliness of perishable food requires that all links in the cold chain must have high organization and coordination.

(3) The development of cold chain is lagging behind, which has a great impact on resource conservation, food safety and farmers' income.

The backward development of cold chain in China has brought five direct adverse consequences.

1, serious waste of resources.

The development of cold chain lags behind, which leads to the loss of perishable food, especially primary agricultural products.

2, food safety hazards

A large number of toxins will be produced in the process of decay and mildew of agricultural products and processed food, which will cause great harm to human body and affect people's quality of life and health.

3. Affect farmers' income.

"Agriculture, countryside and farmers" has become an important issue affecting national economic and social development.

4, affect the price stability

As mentioned above, the time difference between supply and demand leads to high quality and low price in production season and low quality and high price in non-production season; On the other hand, when the earthquake, snowstorm, freezing damage and so on cause poor supply or insufficient output, the market price soars.

5. The circulation cost is too high.

Due to the high loss during transportation,

4) Guangdong, as a big economy and population province, has a serious shortage of cold chain development.

Guangdong is a province with a large economy and population, but the cold chain logistics closely related to people's lives and agricultural production is also quite backward.

(E) China's food safety problems are frequent, and government supervision departments have been pushed to the forefront.
