Development history
In order to avoid the inherent defects of traditional organic antibacterial agents and inorganic antibacterial agents, Rong Sheng refrigerator shifted the research focus of antibacterial agents to the field of bioengineering technology.
(1)1999, the first generation of Rong Sheng Xianhuanbao technology was born. According to food preservation experts, the ripening of fruits and vegetables by ethylene gas and the reproductive damage of microorganisms (bacteria) have always been two major obstacles to the preservation of food in the refrigerator, and the technology of nourishing fresh magic treasure uses rare metals to decompose the ripening gas ethylene produced during the storage of fruits and vegetables, which effectively overcomes the problem of keeping fruits and vegetables fresh in the refrigerator.
② In 20065438+0, the second generation of "Magic Treasure for Enzyme Sterilization and Preservation" came out, which added lysozyme sterilization technology and nanotechnology on the basis of palladium particle decomposition technology. Tested by Guangdong Institute of Microbiology according to relevant national standards, the removal rates of Staphylococcus aureus and Escherichia coli, the most common spoilage bacteria in food, reached 99.88% and 99.99% respectively. The mildew-proof grade reaches the first level, and the ethylene removal capacity is doubled.
(3) In 2002, the third generation of "the magic weapon for keeping fresh with negative ions" came out and was applied to Rong Sheng series refrigerator products. On the basis of the second generation of fresh-keeping magic treasure, the negative ion generating block is added, which can continuously generate negative ions, effectively inhibit the activity of enzymes in the metabolism of fruits and vegetables, inhibit the production of ethylene and the growth and reproduction of germs, increase the moisture in the air, and achieve the best humidity of fresh-keeping fruits and vegetables.
④ In 2004, Rong Sheng introduced Poké mon preservation technology with VC. VC nourishing magic treasure has triple preservation, the first is: PU deodorizing layer+catechin, which can deodorize quickly and effectively sterilize and inhibit bacteria; The second weight: palladium-carbon catalyst preservation block+transparent silica gel, which absorbs and decomposes ethylene and delays the self-ripening of vegetables and fruits; The third weight: VC fresh-keeping block, which can slowly release VC molecules into the refrigerator and reduce the loss of vitamin C content in fruits and vegetables.
According to the experimental data of South China Agricultural University, using VC to raise fresh magic treasure refrigerator has obvious effect on keeping the water content of fruits and vegetables and reducing the loss of vitamin C content, in which the water content and VC retention rate of spinach and cabbage are increased by more than 20%.
VC technology is still widely used in Rong Sheng series refrigerators. The Ayffre series refrigerators, which are still being popularized in Rong Sheng, still use this technology, and cooperate with the nano-water mist preservation technology to pursue better preservation effect.
