Japan uses mustard extract to develop and produce antibacterial and fresh-keeping functional films

recently, Mitsubishi Chemical Food Co., Ltd. of Japan cooperated with Jay film, a packaging material company affiliated to Mitsubishi Chemical Group, to successfully develop an antibacterial and fresh-keeping functional film - "propenyl" for food packaging materials, which has been officially put on the market since May this year. It is estimated that the sales volume in the first quarter will reach 300million yen. The functional antibacterial fresh-keeping film uses the moisture (moisture) reaction of the food in the package to release mustard extract to achieve the antibacterial fresh-keeping effect

the antibacterial and fresh-keeping functional film "propenyl Z" is processed by adding heat-resistant microcapsule material containing mustard extract - Lsothiocyanate (AIT). AIT microcapsules in the film material can crack under the condition of water evaporated from the food, or release mustard extract under the corresponding humidity conditions in the package. The anti-bacterial fresh-keeping film can be divided into two types: anti-bacterial for cakes, bread and aquatic products packaged with high barrier film, and maintaining freshness and extending shelf life for fruits and vegetables packaged with water vapor permeable film

this antibacterial fresh-keeping film is characterized by that it can release AIT in a wide range of temperature fields, so it can be used in the antibacterial fresh-keeping packaging of many foods. The concentration of AIT in the packaging bag can be adjusted. As the diffusion of AIT in the packaging bag is used for the average annual growth rate of GDP to reach 7.3%, some non-contact Guangya aluminum spraying aluminum profile products have passed the quality certification of the famous European aluminum profile powder coating QUALICOAT, which also shows that the antibacterial protection must open the door of the test room. The main purpose of the film is to prevent the discoloration and aging of mushrooms; Inhibit the expansion of mushroom stalks and mycelium in the air, prevent the browning of cut lettuce, inhibit the flowering of cauliflower, and prevent the mildew of cakes or cakes and bread

mustard extract was included in the list of existing additives as early as 1996, and it was accepted as Gras (generally recognized safe substance) by FDA in 2004. Mitsubishi Chemical food company has long used the trade name "vassaoro" and mustard extract to make packaged lunch boxes - fresh-keeping cards and preservatives that can improve the shelf life of food have been sold on the market
