Low-temperature fresh-keeping technology builds a strict fresh-keeping defense line for the food in the refrigerator through precise control of temperature, humidity and gas environment, and comprehensively guarantees the quality of food.
The core of low-temperature fresh-keeping technology lies in stable and precise temperature control. Different from the frequent temperature fluctuations of ordinary refrigerators, refrigerators equipped with this technology can maintain the internal temperature in an extremely stable low-temperature range. When food is placed in the refrigerator, the suitable and constant low-temperature environment can effectively reduce the activity and respiration intensity of microorganisms in the food. This is like pressing the "slow-motion button" for food, slowing down the metabolism of cells inside the food, so that the food can be kept in its initial fresh state for a longer time after picking or slaughtering, and avoiding the rapid decay and deterioration of food due to unstable temperature.
On the basis of precise temperature control, low-temperature fresh-keeping technology also pays great attention to the regulation of humidity environment. During the storage process, many ingredients are prone to water loss due to the dry environment in the refrigerator, which leads to poor taste and loss of nutrition. The refrigerator with low-temperature fresh-keeping technology can maintain moderate humidity in the internal space under low temperature environment through special moisturizing devices and circulation systems. In this way, the moisture on the surface of fresh fruits and vegetables will not be quickly drained, and they can still remain plump and moist; the meat will not become dry and woody due to excessive loss of moisture, and it will always maintain a fresh and juicy taste, so that the ingredients can maintain their original quality for a long time.
In addition to temperature and humidity, the optimization of the gas environment is also an important part of low-temperature fresh-keeping technology. The oxygen inside the refrigerator will accelerate the oxidation process of the ingredients, causing the ingredients to change color, taste, and even lose nutrients. Low-temperature fresh-keeping technology effectively reduces the oxygen content in the refrigerator through the gas circulation and purification system, and promptly discharges the ethylene and other ripening gases produced by the respiration of the food. At the same time, the concentration of carbon dioxide is appropriately increased to form a gas environment that is not conducive to the growth of microorganisms and the oxidation of the food itself. This improvement in the gas environment is like creating an exclusive "fresh-keeping cabin" for the food, further extending the shelf life of the food and locking the color, flavor and nutrition of the food.
Low-temperature fresh-keeping technology also has the ability of intelligent adjustment. It can automatically adjust the temperature, humidity and gas environment parameters according to the type and quantity of food placed in the refrigerator. When a large amount of fresh vegetables are put in, How does low-temperature fresh-keeping technology ensure the quality of food in a stainless steel vertical refrigerator? will automatically enhance the moisturizing function and optimize the gas circulation to provide the most suitable storage conditions for vegetables; when meat and other ingredients that need to be stored at a lower temperature are put in, How does low-temperature fresh-keeping technology ensure the quality of food in a stainless steel vertical refrigerator can quickly adjust the temperature to the appropriate range and enhance the effect of low-temperature fresh-keeping, ensuring that different types of ingredients can be stored in the best environment and fully guaranteeing the quality of ingredients.
In terms of space design, low-temperature fresh-keeping technology is closely combined with the zoning layout of How does low-temperature fresh-keeping technology ensure the quality of food in a stainless steel vertical refrigerator?. How does low-temperature fresh-keeping technology ensure the quality of food in a stainless steel vertical refrigerator? is usually equipped with special low-temperature fresh-keeping cabins, which use special insulation materials and sealing designs to minimize the interference of external heat and moisture and maintain a stable low-temperature fresh-keeping environment in the cabin. Whether it is storing precious seafood ingredients, or medicines and health products that require special preservation, the low-temperature fresh-keeping chamber can provide precise temperature and humidity control to avoid mutual influence between different ingredients, so that each ingredient can be carefully cared for.
Low-temperature fresh-keeping technology also further guarantees the quality of ingredients by reducing the loss of nutrients in ingredients. Under stable low temperature, moderate humidity and optimized gas environment, the vitamins, minerals and other nutrients in the ingredients can be better preserved. When people eat these ingredients preserved by low-temperature fresh-keeping, they can not only taste the fresh taste, but also take in sufficient nutrition, which truly realizes the strict guarantee of the quality of ingredients from storage to consumption, so that every ingredient can play its maximum value.
