In the hot summer, high temperatures not only test people's endurance, but also affect our diet. In people's traditional impressions, want to maintain the freshness of the ingredients, the low temperature environment of the refrigerator is the key to preservation. However, more and more consumers have found that although the old refrigerators in the home can keep the temperature low, the preservation effect is not satisfactory. Why? In fact, this has a lot to do with the unstable temperature control of the old refrigerator and the lack of fresh-keeping technology. The fresh-keeping technology of the new fresh-keeping refrigerator is often not available in the old refrigerator, which is the root cause of the “poor preservationâ€. In order to more directly prove the above viewpoint and popularize the healthier and correct method of fresh-keeping foods for consumers, Jingdong Appliances has launched a period of preservation for the fresh-keeping refrigerators of the seven brands of Midea, Siemens, Meiling, Jinghong, Hisense, Samsung and LG. 15 days of "refrigerator preservation test"; at the same time, Jingdong Appliances commissioned China Household Electrical Appliances Research Institute for 7 days of professional data evaluation and sensory evaluation, supporting and endorsing the new fresh-keeping refrigerators participating in this event. 　　 In the experiment, fresh fruits were sealed into the new fresh-keeping refrigerators of the above seven brands, and compared with the old refrigerators. After 15 days of waiting, the result of long-lasting fruit preservation was unexpected. Comparison of fruit changes in new and old refrigerators (left is the new fresh-keeping refrigerator) It can be seen that the surface of the fruit sealed in the fresh-keeping refrigerator has some water loss. It is still relatively solid when the fruit is cut inside. However, the fruit in the old refrigerator has obvious dry state, and some have begun to undergo mildew, and there are obvious Odor. A group of pictures directly allows consumers to see the changes in fruits and vegetables in these 15 days, and the strength witnesses the preservation effect of the seven brands of refrigerator products. Home appliance institute test comparison of fruits and vegetables in new and old refrigerators (left is the new fresh-keeping refrigerator) It can be clearly seen from the above figure that in the daily life state, the daily changes of fruits and vegetables in the new and old refrigerators clearly show that the preservation effect shows a significant difference. In order to judge the fresh-keeping effect of new and old refrigerators more rigorously, the “Microbiology Research Office†of China Household Electric Appliance Research Institute launched a seven-day evaluation of vegetable storage and preservation effect, using scientific algorithms, using weight loss rate (weighing before and after storage), vitamins. Calculated formulas such as C retention rate and chlorophyll retention rate, and calculated the freshness of the ingredients in different refrigerators. According to the data released on the spot, it can be seen that the weight loss rate and vitamin C retention rate of the old refrigerators are unqualified. The fresh-keeping refrigerator has a vitamin C retention rate of 95.07 and a chlorophyll retention rate of 95.87, which is higher than that of the old refrigerator. Event site home appliance institute announced & displayed data So, what kind of preservation technology is there, so that the refrigerator can have such a qualitative leap in the nutrition and preservation of ingredients? At present, there are roughly five common preservation technologies on the market, namely “zero-degree preservation technology, VC preservation technology, vacuum preservation technology, photosynthetic preservation technology and silver ion antibacterial preservation technologyâ€, and their focuses are different. For example, the “Zero Bio-preservation Technology†of Siemens Home Appliances, through the iSensoric intelligent system, monitors the temperature and humidity status at any time, so that the refrigerator storage room is always in a relatively stable, independent, very close to 0 ° C temperature state, and maintain a certain humidity It will not freeze the food, but also benefit from the ultimate preservation status brought by the freezing point. It is especially suitable for storing sashimi foods. The "vacuum preservation technology" can extract the air in the refrigerator storage room to create a dry and gas-tight environment for the ingredients. Like the “Platinum Cleansing Technologyâ€, the Platinum Cleansing Device built into the air-conditioning system continuously decomposes the odor in the refrigerator to provide a healthier storage environment for food. Beautiful platinum pure taste preservation technology More like Meiling's "water molecule activation and preservation technology", by vibrating the water in the food, activating water molecules, reducing the activity of the enzyme, reducing the damage to the cell membrane, reducing the loss of juice, solving the short preservation time of the food, thawing blood, The painful consumption of bags in the fresh-keeping period provides users with a new experience of long-term preservation. In addition to the advancement of fresh-keeping technology, the new fresh-keeping refrigerators are not too much in other respects. Take refrigeration, the application of intelligent temperature sensing, temperature control system and high-efficiency inverter compressor, so that the new fresh-keeping refrigerator will never be "suddenly hot". In addition, the more scientific and reasonable multi-circulation system also provides great help for fresh-keeping; through the multiple air ducts inside the refrigerator, the solenoid valve and the fan are used to realize the conversion between the loops, where is the need for cold air to send, At the same time, it maintains a stable low temperature state, and the temperature fluctuation is smaller. Some new fresh-keeping refrigerators adopt a dual-system multi-cycle design, so that the refrigerator has two sets of heat exchange systems, and the refrigeration and refrigeration independently operate without mutual interference, completely solving the trouble of food odor. . Compared with the old refrigerator, the new fresh-keeping refrigerator with excellent preservation technology and new design can greatly change our life and make our diet more healthy and fresher. As one of the large-scale industry platforms, Jingdong Appliances not only wants to popularize the health preservation refrigerator, but also gives consumers a welfare discount. It is reported that July 10 will usher in the Jingdong platform refrigerator washing machine super category day, many refrigerators participating in this test are also in the promotion activities, there are 455 liters cross-air-cooled refrigerator as low as 1999 yuan, 10 kg inverter drum fell below 2,000 yuan, every 100 famous brands to reduce 100 activities, but also enjoy the "white interest-free" activities, can be said to be a package of health benefits.
