Nanchang Taikang develops edible strawberry preservative

Recently, an edible composite strawberry preservative was successfully developed at Nanchang Taikang Food Science and Technology Co., Ltd. The preservative adopts natural edible ingredients, has simple operation and low cost, does not affect the original appearance, taste and flavor of fresh strawberries. It can be preserved under refrigeration conditions for 15 days, and can be maintained at room temperature for about 7 days, greatly prolonging the storage period. , providing a strong guarantee for the circulation of fresh strawberries.

According to reports, the company's edible composite coating strawberry preservative (TKB-CM) is based on edible thickeners as raw materials, using the complementarity of carrageenan and guar gum film and thickening, and then adding complementary The emulsifier is formulated.

The preservative can form a semipermeable membrane atmosphere on the surface of strawberry, and utilizes the microporous structure of the membrane to control the respiratory intensity of the strawberry cells so that the cellular tissues enter a dormant state and inhibit the oxidation and enzymatic browning of the strawberry. Can prevent and inhibit the growth and reproduction of microorganisms, so as to achieve color protection, water retention, preservation, greatly reduce the loss of soluble solids and Vc content during storage, so that the fresh strawberry's sensory quality is good, extend the shelf life of strawberries. After testing, fresh strawberries are treated with the film preservative and can be stored for 15 days under refrigerated conditions and can be stored for about 7 days at room temperature. Untreated fresh strawberries can only be stored for 2-3 days. At present, the company is applying for a national patent and is planning to produce it on a large scale.
