Modern canned food has a history of more than 200 years since its birth. Although food production technology is changing with each passing day, and a variety of processed foods are dazzling, canned food, as a safe, hygienic, nutritious and convenient food, has always been closely related to people's lives and plays an important role in such scenes as aerospace, military supplies, disaster relief, exploration, tourism and daily life. The canned food industry is a traditional food industry in China. For many years, it has played an important role in supplying domestic demand, earning foreign exchange through exports, serving agriculture, rural areas and farmers, meeting healthy consumption, and steadily expanding employment. Canning industry is a typical industry and a powerful hand to enhance the added value of agricultural products. The production, purchase and supply of raw materials for the canning industry originate from the countryside. The development of the canning industry is of great value for improving the added value of agricultural products, increasing farmers' income and realizing a virtuous cycle of rural economy. Consolidating and developing the international market is an important direction of China's can industry. Canned food is an important part of the daily diet of many overseas consumers. In European and American countries, the per capita annual consumption of cans can reach 50-90 kg. During the epidemic period, especially in 2020, the sales of canned meat, canned chickpeas and canned tuna in the United States increased by 31.8%, 25.6% and 24.9% year on year, respectively. The sales of canned vegetables in Germany increased by 80% and the sales of canned fruits increased by 70%. The sudden epidemic has highlighted the emergency security attribute of canned food. Canned food has won more attention, which is also an important opportunity for China's canned food industry. China is a big country in canning production and export in the world. In more than 70 years of development of the contemporary can industry, small-scale, multi variety, small batch, single machine and manual operation based production type can factories have grown into production and operation type can enterprises with different characteristics in large, small and medium-sized, basically realizing specialization and mechanization. However, compared with the international advanced level, the overall mechanization, automation and intelligence of China's canning industry still lags far behind. The construction of a safe, high-quality and stable raw material base cannot meet the needs of production development. There is a lack of strong brands in the international market, and the industry's weaknesses need to be supplemented. To lead the industrial transformation and upgrading with scientific and technological innovation, and promote the industry to move towards quality and efficiency. Innovation is the key to the sustainable and stable development of the industry. The automated production lines for canned fruits, such as yellow peach and orange, are maturing, the processing process is speeding up, and the efficiency is constantly improving; The tin plate ultra-thin can manufacturing technology can effectively save the cost of can making materials, reduce resource and energy consumption; The new material of coated iron has been successfully developed to fill the gap in China and become the first choice for canned food packaging. Canning enterprises have made some achievements in realizing mechanization and automation of processing, improving the competitiveness of products, but they still need to continue to work hard. Extending the industrial chain, upgrading the value chain and improving the supply chain are the "golden keys" to improve the quality and efficiency of the industry. We will strengthen the pre production analysis of bulk export varieties, discuss countermeasures and jointly build rules, adhere to the principle of reasonable raw material prices, protect farmers' interests, do not hurt farmers by depressing prices, and keep the bottom line of the industry. To stabilize export prices, determine production based on sales, ensure processing interests, hold the profit threshold, and promote complementary advantages, coordinated development, and mutual benefit and win-win results among industry enterprises. Deeply implement the quality improvement action, and promote the canned industry to "increase varieties, improve quality, and create brands".
