1. The physiological and biochemical mechanisms of litchi browning and the causes of peel browning were studied in terms of enzymes, pH value, ascorbic acid, phenols, and respiration. The paper was published as a paper and was read at an international post-harvest symposium. 2. On the basis of theoretical research, formulate comprehensive technical regulations for storage and transportation of litchi. According to this regulation, litchi can be stored for 30-35 days at a suitable low temperature. Good fruit rate 85-90%, shelf life 1-2 days. Litchi can be kept fresh for 4-5 days under normal temperature conditions. 3. To ensure that the quality of litchi sources is an important condition for good storage and preservation, it is best to control the pre-harvest cultivation management and pest control work. The advanced nature of technology: The research on the storage, transportation and preservation of litchi is the focus of the Ministry of Commerce's “6th Five-Year Planâ€, the provincial “Eighth Five-Year Plan†and the Ministry of Agriculture. This technology is advanced, convenient and practical, and has strong operability. This study won the third prize for scientific and technological progress of the Ministry of Agriculture and the second prize for scientific and technological achievements of Guangdong Province. This technology is characterized by the integration of pre-harvest cultivation, pest control technology and post-harvest preservation technology assembly. This is the world's advanced mode of fruit production and commodity circulation. Scope of application: Applicable to fruit companies, export trading companies and fruit farms and other units or specialized households. Production conditions: 1. Low-temperature storage and transportation: cold storage and refrigerated trucks, ships, preservatives and packaging are required. 2. Storage and transportation at normal temperature: general warehouses and trucks, ships, preservatives and packaging. Market Analysis: In recent years, the production of litchi in Guangdong, Guangxi, and Fujian provinces has developed rapidly. The demand for litchi in the northern provinces, Hong Kong and Macao markets and foreign markets is very large. However, due to the lack of preservation technology, the post-harvest losses are generally serious. Litchi is China's strongest competitive product in domestic and foreign fruit markets. This technology will play an important role in promoting domestic sales of litchi. Investment analysis: Cold storage or refrigerated trucks need to be rented at low temperature, and those who have conditions can invest in cold storage (about 800-100,000 RMB for 100 tons of cold storage). Preservatives are about 50 yuan/ton. Application examples: This technology has been promoted and applied in production. It has successively instructed Xili Lake Fruit Farm in Nanshan District of Shenzhen City, Guangzhou Cereals, Oils and Foodstuffs Import & Export Corporation, Guangzhou Agricultural Development Corporation, Dongguan Fruit Development Company, Fujian Zhangzhou Jinyu Company and other units. The storage of litchi origin, north transport or export has achieved significant economic and social benefits.
These goji come from Himalayan area, plateau snow irrigation, pure and pollution free. Goji berries taste sweet, can be eaten directly as snack, it's a very popular healthy food in the world.
We are Goji Berry's manufacturer, the annual output of 2000 tons wolfberry fruits. The bases are close to the Yellow River, with plenty of sunlight, and the temperature differences of day and night, which is conducive to the growth of goji berry.
