Jiangnan University R & D Fruit Peach Fresh-keeping Packaging Technology Makes New Achievements

"The same is a peach packing box, ordinary can only save 2-3 days, and this application of preservation technology can be preserved, preserved for 6 or 7 days, shipped to Beijing and even abroad have no problem. More importantly, each The box is 1-2 yuan more expensive and is allocated to 1,2 cents per peach. Compared to transportation costs and losses, the freshness of the storage box is too high!" Qian Junhao, an associate professor at Jiangnan University, and the new Peach Fresh Packing Box produced by the R&D team were very popular. The Yangshan farmers were scrambling to purchase the first batch of 5,000 listed products that were almost sold out in only half a month.

Wuxi Yangshan peaches are loved by consumers because of their brilliant colors, good taste, and rich juice. However, because of its high moisture content, perishability, and difficulty in long-distance transportation, the sales radius of peaches has not been opened. In order to solve this problem, Jiangnan University, together with Beijing Institute of Graphic Communication, Xi'an University of Technology and China Packaging Corporation, and other organizations, after nearly 10 years, jointly research and development of "peach peach fresh-keeping technology and materials at room temperature."

According to Qian Junhao, technical director of the project, Jiangnan University’s associate professor and master’s tutor, “Peach fresh-keeping packaging film, made of food-grade nanomaterials, has the function of automatically adjusting the concentration of oxygen, carbon dioxide, and water vapor. Naturally slows down the aging process of peaches without spraying any chemical preservatives.” After laboratory tests and field applications, the peaches using this technology can be stored for 7-8 days at room temperature of 25°C-39°C at room temperature. Small fresh-keeping bags, up to about 15 days, and no difference in color, flavor, taste and just picking.

Jiangsu Wanguo Peach Fresh-keeping Technology Co., Ltd., with this technology as its core, officially released new products such as new technology, fresh-keeping bags and fresh-keeping moisture-proof stickers last year, which has been initially recognized and praised by the market. But at the same time, fruit growers also reflect issues such as cost and inconvenience.

"Good technology has been achieved, but there is still a need for good ways and products to really benefit the market." Qian Junhao told reporters that during the year, they thought of the combination of cling film and fruit box, and independently developed a set of automatic The film production line realizes mass production. “Originally, the fruit growers need to open the storage bags one by one and then put the peaches one by one to tie them in. This has increased a lot of packaging links; now they use boxes directly, just like ordinary peach boxes. Convenient, and the cost is reduced, but the freshness can be extended by 4-5 days."

With the maturity of room temperature preservation technology and deep market exploration, the Jiangsu Wanguo scientific research team has received invitations and cooperation from the governments of the “China's First Peach County” and Mengyin County of Shandong Province and the Fruit Farmers Association. Qian Junhao said that The packaging and packaging structure of fresh fruit products will be refined, and will continue to study the technology of fresh-keeping packaging of bayberry, clams, litchi, and fruits of Gannan navel orange and Chinese wolfberry fruit of Ningxia, and will accelerate the development of the fruit industry.
