"We have obtained preservative sales qualifications in many places globally"

Recently, Shandong Aoweite Biotechnology Co., Ltd., a Chinese preservative manufacturer, announced that the company has obtained sales qualifications in multiple markets in Europe, North America, and South America.

Its series of preservative products can now be formally sold directly in these markets.

Shandong Aoweite has been engaged in the research and development of the fresh-keeping industry of fruits and vegetables for more than 25 years and is committed to the post-harvest physiological research of flowers, fruits and vegetables and related technology.

"At present, our series of preservatives include 1-MCP powder, tablets, sachets and other products," introduces Wang, who is international sales manager of Shandong Aoweite: "We have successively obtained sales qualifications in these markets since 2021. At present, the regions where we can sell include Poland, the United States, and Argentina. However, due to the pandemic, market competition, and many other reasons, we have not made an official announcement. With the easing of the pandemic, there are more and more inquiries from customers, and we think it is necessary to announce this news.”

Taking apples as an example Wang introduced the application for that specific crop: "For producers, whether they use cold storage or controlled atmosphere storage, as long as they control the activity of ethylene, they can extend the storage period of apples by 3 months while maintaining their nutrition, firmness and taste."

"1-MCP is a competitive inhibitor of ethylene. When 1-MCP is applied before endogenous ethylene production or exogenous ethylene action in plants, it will pre-emptively bind to ethylene receptors, thereby the maturation process of apples is suspended. Only when the fruit leaves the cold storage and is exposed to normal air, the pulp cells will produce new ethylene receptors again, and a series of physiological and biochemical reactions related to ripening will restart," explains Wang.

"The freshness of apples will be well preserved during this period. Treated with our Logfresh technology, the fruit's ethylene receptors are combined with 1-MCP in just 24 hours in cold storage. After 24 hours, routine storage management of apples in cold storage can be carried out, which can effectively reduce storage diseases of apples, maintain product hardness, crispness, color, flavor, aroma and nutrition. "

"For small and medium-sized customers who do not have large-scale cold storage, they can use our small-sized products in fruit cartons." Wang said, "The use of the product is very simple, just put it in the fruit carton. 1 piece can handle 10-15KG fruit."

Modified anti-fog atmosphere packages
In addition, anti-fog modified atmosphere fresh-keeping packaging is also one of the main products of Shandong Aoweite.

"Our Logfresh anti-fog modified atmosphere packaging combines moisture-permeable, modified atmosphere, anti-fog and other functions in one packaging solution to provide the highest quality fruit and vegetable products in the market. By changing the proportion of each component in the formula, the moisture permeability of different films can be adjusted according to the needs. It has strong adjustability and a wide range of applications, and is suitable for fresh-keeping and storage of many varieties of fruits and vegetables."

Wang continues: "The advantage of anti-fog modified atmosphere packaging is that the hydrophilic group in the product can absorb water molecules in the air and reduce the surface tension of the film, so that the water molecules can wet and diffuse on the film surface before forming tiny water droplets on the film surface, thus forming a layer of the super thin and transparent water film."

The product  will no longer scatter incidental light, and will not interfere with the line of sight, thus playing the role of anti-fog. While prolonging the fresh-keeping time, it does not affect the taste of the fruit. Under the same storage conditions, Logfresh anti-fog modified atmosphere packaging can extend the fresh-keeping time by 1.5-3 times.

Shandong Aoweite Biotechnology Co., Ltd. is committed to providing fresh-keeping solutions for major fruit and vegetable suppliers around the world. The company's products cover the entire agricultural product supply chain. "Whether it's in the farmer's field, the cold storage of the warehouse, the logistics transport vehicle, or the packaging factory, we can customize according to the demand for product preservation and provide the products required by the customer.
