How to effectively prolong the freshness period of fresh agricultural products is a problem to be solved in the production and circulation of fruits and vegetables. According to Mr. Zhao Rongliang from Lushang Liangpin Agricultural Technology Linyi Co., Ltd.: the company has made a breakthrough in the room temperature preservation technology of fruits and vegetables. One of the core products, the "preservation liquid" is applied to the outer packaging of fruits and vegetables, which can extend the freshness period by more than 4-19 days on the original basis.

"The principle is to use a variety of raw material synthesis technology to inhibit the factors that cause the rot and deterioration of fruits and vegetables, such as the production of microorganisms and the efficiency of enzyme action, so as to prolong the preservation period. This technology is obtained by the R&D team through the integration of multidisciplinary fields including minerals, polymers and nanomaterials, and biochemistry, with targeted experiments. With this fresh-keeping solution, fruits that are close to ripeness can be picked at the source of production. Part of the air transport can be converted to land transport, which helps to reduce transportation costs and logistics losses," said Zhao, when introducing the principle and value of this technical product.
"In application, we provide materials and technologies to manufacturers of packaging. This product is currently more suitable for paper packaging boxes. When manufacturers produce cartons, they add this preservative solution during the process of producing corrugated paper from coated paper. The composite material in it plays a role so that the produced "fresh-keeping cartons" can extend the fresh-keeping period and retain the aroma and nutrition of fruits and vegetables to a certain extent.

"The advantages of this product also include controllable costs and that it is environmentally friendly. Our goal is that the cost of adding this technology to cartons only needs to increase by 20%. This will reduce the logistics loss of products and the expenditure on the post-sale of fresh products. On the other hand, reducing the loss and reusing fresh-keeping cartons are all conducive to energy conservation, environmental protection and pollution reduction.”
According to Zhao, the company's founding team includes experts and professors from various scientific research institutes, and currently has 11 authorized patents. The core of the product technology is fresh-keeping at room temperature, and the product solutions based on this include fresh-keeping cartons, fresh-keeping films, fresh-keeping paper, and fresh-keeping liquids. The product is currently suitable for the outer packaging of 29 kinds of fruits including apples, apricots, avocados and bananas, and 17 kinds of vegetables including broccoli and cabbage.
