Who invented the refrigerator, a high-tech technology, which really solved human problems, especially when the weather is getting hotter and hotter, and I feel that I can't live without the refrigerator. In fact, this kind of thing has been recorded as early as ancient times.
During the Warring States Period of more than 2,000 years, daily necessities similar to refrigerators appeared. At that time, its name was "Bing Jian". Ice guide is a double-layer container with a bucket inside. In summer, putting ice cubes in the kitchen can play a cooling role.
The long summer is coming and the weather is getting hotter every day. At this time, the refrigerator began to play a role. Many ingredients should be kept fresh in the refrigerator to avoid wasting food due to high temperature deterioration.
However, not all ingredients can be kept fresh in the refrigerator. The following four ingredients can't be put in the refrigerator, because they can't keep fresh and will accelerate decay. Many people don't know that for the health of their families, we should never ignore it.
One: ingredients with high starch content
This kind of food includes potatoes, sweet potatoes, yams and so on. This kind of vegetables have a similar feature, that is, they are rich in starch, which will accelerate decomposition at low temperature and affect the taste. At the same time, the refrigerator will release water vapor due to refrigeration, and the overall environment is humid. Root vegetables, such as potatoes and sweet potatoes, are particularly prone to germination and deterioration in humid environment. Friends with common sense know that sprouted potatoes contain toxins and may vomit after eating them.
Two: tropical fruits
Everyone is used to keeping inedible fruits fresh in the refrigerator, but some tropical fruits not only can't keep fresh, but also accelerate decay. For example, as a tropical fruit, banana's cell wall has no protective mechanism against cold environment, so after being put in the refrigerator, low temperature will change its texture, make it unable to mature normally, and the digestive enzymes in the pulp will slowly lose, so it is not suitable for being stored in the refrigerator. Similarly, it is not suitable for pitaya, kiwi and mango.
Three: overnight seafood
This is the last time to serve seafood. Crabs, shrimps and all kinds of fish are delicious in many people's mouths. However, the endless seafood will be kept in the refrigerator and then taken out for heating the next day. This is absolutely not desirable, because the protein content of seafood such as fish, shrimp and crab is high, and it is easy to produce protein degradation products overnight. After people eat seafood overnight, these protein degradation products will damage liver and kidney functions and affect human health.
Four: overnight cold salad
Everyone will put the inedible cold salad in the refrigerator and take it out for the next meal. It's cool to feel cold. In fact, this is impossible. The process of cutting vegetables and seasoning is also susceptible to bacterial contamination. Cold salad often exceeds the standard after overnight, which is easy to cause gastrointestinal problems after people eat it.
The above is today's sharing. Refrigerator solves many problems in life, but refrigerator is not everything. Not all ingredients are suitable for keeping fresh in the refrigerator. The above four kinds are not suitable for storage in the refrigerator. For the health of family members, everyone must pay attention to it.
