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

[Chinese Packaging Network News] "The same is a peach packaging box, the 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 or even abroad have no problem. The important thing is that each box is 1-2 yuan more expensive, and it is allocated to 1,2 cents per peach. Compared with transportation costs and losses, the freshness of the storage box is too high!" During the hot period of Jingtao, Qian Junhao, an associate professor at Jiangnan University, and the new peach fresh-keeping package box developed by the R&D team were very popular. The Yangshan fruit growers rushed to buy, and the first 5,000 listings 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 selling radius of peaches has not been opened. To solve this problem, Jiangnan University, together with Beijing Institute of Graphic Communication, Xi'an University of Technology and China National 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, and gained initial recognition and praise from 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, 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; it is now directly used in boxes, and it is packed in the same way as regular peaches. 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 government of the “First Chinese Honey Peach County” Mengyin County of Shandong Province and the Association of Fruit Farmers. Qian Junhao said the next step The packaging and packaging structure of fruit fresh-keeping products will be refined, and will continue to study the technology of fresh-keeping packaging of bayberry, clams, litchi, and fruits of Gannan navel oranges, medlars of Ningxia, and so on, to accelerate the development of the fruit industry.
