Old refrigerator VS fresh refrigerator food preservation effect in the end can be much worse?

Preservation is the most essential function of the refrigerator. The appearance of the refrigerator provides people with space for food to be refrigerated and frozen, which delays the process of oxidation and dehydration of food. In the past few years, domestic refrigerators have been exerting efforts in air-cooling, multi-door, and frequency conversion. However, in 2018, refrigerator companies have returned to the essence of the refrigerator, and began to re-examine the preservation of the refrigerator. The preservation of the refrigerator not only ensures the natural freshness of the ingredients, but more importantly, ensures the health of the ingredients. Then, how much difference can an ordinary old refrigerator and a new type of fresh-keeping refrigerator have in terms of food preservation? In order to solve this confusion, Jingdong Home Appliances launched a refrigerator fresh-keeping sealing test.

On June 23, Jingdong Appliances, together with seven well-known refrigerator brands such as Midea, Siemens and Meiling, launched a storage refrigerator storage test in Beijing Longde Plaza with the theme of “sensitive freezing time and locking fresh”. At the event site, the fresh-keeping effect of seven new fresh-keeping refrigerators and two old refrigerators was carried out, and a 15-day food storage and preservation effect test was launched.

For the function of the refrigerator, many consumers only stay on the level of refrigerating and freezing. It is not known that the different refrigerators have different freshness levels for the ingredients. In the past concept of people, ordinary vegetables and fruits stayed in the refrigerator for a week, even if they would not deteriorate and rot, they would shrink into a ball.

But in fact, many new refrigerators have been able to extend the shelf life of the ingredients. Sun Zhitao, general manager of the ice washing and sales department of the Home Appliances Division of Jingdong Electronic Entertainment Group, said that the purpose of this activity was to let more consumers understand this, understand the preservation function and technology of the refrigerator, and let consumers More intuitive recognition of the drawbacks of the old refrigerator.

When it comes to the drawbacks of old refrigerators, many consumers may not be clear. First of all, the old refrigerator has an unstable cooling effect, and the ingredients will accelerate the rate of spoilage at the temperature of “fresh and hot”. Secondly, it is unsanitary. Even if the old refrigerator is cleaned every day, it will inevitably affect the mutual influence of food, odor and bacteria. Long-term use will threaten the health of family members.

However, these difficulties in the old refrigerator can be solved with new-style preservation technology. According to the general manager of the Meiling Beijing branch, the refrigerator that participated in the test has the function of water molecule activation and preservation, and has a 0.1 degree frequency conversion, achieving 990-4500 wide speed regulation, allowing the food to linger at a constant temperature and improving preservation. Freshness and taste. At the same time, 360 ° cycle air supply, anti-stringency, food cooling and mild, more effective to avoid the breeding of bacteria.

At the event, under the leadership of the host, the heads of seven brands including Midea, Siemens, Meiling, Jinghong, Hisense, Samsung and LG put the prepared ingredients into new and old refrigerators and put them on the seal. The sealing ceremony and start the countdown. This also means that in the next 15 days, the nine refrigerators participating in the sealing and fresh-keeping test will not be opened until the unpacking activity on July 8 reveals the effect of the fresh-keeping storage test of the new and old refrigerators.

It is understood that during the fruit fruit storage test, the China Household Electrical Appliances Research Institute will simultaneously launch a new fresh-keeping refrigerator and an old refrigerator for the preservation of vegetables. The spinach and green pepper will be preserved and stored, and the weight loss rate and vitamins of the test vegetables will be 7 days later. C retention rate and chlorophyll retention rate were scientifically tested. The evaluation results will be announced at the same time at the opening ceremony on July 8th, so that consumers can not only clearly understand the gap between the old and new refrigerators through professional data, but also have very intuitive photos, so that consumers can clearly see The daily changes in the fruits and vegetables that are eaten in the refrigerator every day.

Want to know how much difference between fresh and old refrigerators in terms of food preservation? Please continue to pay attention to the relevant reports of China National Grid. After 15 days, we will verify together!
