Blueberries are a perishable fruit, which are easily to damage during processing, and are also prone to mildew and dehydration in storage and logistics. This also brings great difficulties to the transportation, storage and sales of blueberries. The preservation of blueberries has also become a topic of special concern to the industry.
Sam is the sales manager of Shandong Maigena Materials Technology Co., Ltd., a professional manufacturer and exporter of fruit preservative products. He introduced the company's Logfresh pad for blueberry products to FreshPlaza.
"Sulfur dioxide is an active ingredient that can effectively inhibit mold and has been widely used in the field of table grapes. It is not common to use this gas to extend the shelf life of blueberries. Our Logfresh pad extends the fresh-keeping period of blueberries by releasing sulfur dioxide. "
According to Sam, the Logfresh preservative pad is mainly used in the field of fresh grapes. However, with the continuing increase of blueberry imports and local production, more and more companies contact and consult about blueberry preservative products. Therefore, the company began to improve the technology on the basis of the existing pad for grapes, and developed similar products especially for blueberry products by adjusting the concentration of sulfur dioxide.
"In addition to fruit categories, blueberries of different origins and varieties have different requirements for preservation. To this end, we will understand the characteristics of products and customer needs through communication and make customized solutions. "
"Compared with similar products on the market, the sulfur dioxide emission rate of our Logfresh pad is very stable, which can ensure the uniform and stable gas concentration in the package. In addition, we control the concentration of sulfur dioxide at a low level to avoid the influence of gas on the color and taste of products to the greatest extent. The shelf life of blueberries using fresh-keeping pads can be extended by about 30%."
Experimental comparison: After fresh blueberries were stored at 2°C for 56 days, the changes in blueberries in Logfresh (left) and traditional packaging (right) were compared.
In terms of product research and development, in addition to self-research, Shandong Maigena Materials Technology has cooperated with many domestic scientific research institutions in different forms, constantly optimizing production technology and technological process, improving the function and performance of products and improving the cost performance. At present, the company's fresh-keeping products have been registered in South Africa, Chile, Australia and other countries, and have cooperated with distributors in many regions. Now the company is seeking more partners.
