Genetically modified foods have always attracted attention and their safety has always been highly controversial. At present, no consensus has been reached in the world. Before the country announced the list of genetically modified foods in China, the issue of genetically modified foods, which has received much attention, has returned to people's perspective.
Genetically modified foods are really "terrible." In fact, genetically modified foods are actually only one aspect of dietary balance and nutrition. Everyone does not need to panic too much. The following rumors about genetically modified foods should not be taken lightly.
Rumor 1: Fruits and vegetables that are not perishable are genetically modified products
Correct solution conditions can be long-term preservation
Some vegetables, fruits, etc. can be stored for a week or more. Is this related to genetic modification? Experts explain that it is not uncommon for a pumpkin or a tomato to be preserved for one week.
First of all, some varieties are inherently shelf-stable varieties. For example, the Guoguo apple skin, which was common 20 years ago, can be stored for two or three months without being stored in cold storage. People can use these traditional methods to breed these not easily damaged varieties.
Secondly, fruits and vegetables have their own preservation conditions, so long as they are stored under conditions, they can be stored for a long time. For example, apples can be stored in cold storage for 12 months. This has nothing to do with genes. It's just that people use the method of lowering temperature and adjusting the gas composition in cold storage to make apples fall into a state similar to “hibernation†and reduce Its respiration and aging process only.
Even if not in the cold storage, many vegetables and fruits can be kept in the shade for more than a week.
Rumor 2 Off-season vegetables are genetically modified foods
Positive solution Breeding cultivation has nothing to do with transgene
From the perspective of agricultural production, seasonal product quality is better than off-season products. Taking tomato as an example, the content of vitamin C in anti-season tomatoes grown in greenhouses is only half that of open-air planting products in summer. Precocious fruits that are deliberately selected and cultivated often have inferior taste and nutritional value to naturally late-maturing fruits, but this selection and cultivation have nothing to do with genetic modification.
From the perspective of dietary nutrition, no matter which season, eating more fruits and vegetables is the most critical health issue. Numerous studies have confirmed that the greater the total intake of fruits and vegetables, the lower the risk of cancer and heart disease. Eating fruits and vegetables in winter is better than not eating.
In addition, its realization of many anti-season fruits and vegetables, is not necessarily a product of greenhouses, which also have products from the south, or even abroad, there is no seasonal problems, and its nutritional value is not necessarily lower than the seasonal products in the north.
Rumor 3 There is no genetically modified product in processed food
Positive solution of genetically modified components found in processed foods
Processed products come from raw materials for agricultural products. All kinds of pollution ingredients in raw materials, as well as genetically modified ingredients, will go into processed foods. Usually people pay attention to the raw materials of agricultural products and there are concerns about pesticide pollution, residues and genetically modified components in fruits and vegetables. In fact, many genetically modified ingredients are derived from processed products.
For example, the fries that some fast food restaurants sell abroad use mostly genetically modified potatoes; the flours used in hamburgers and hot dogs are also likely flours made from genetically modified wheat. Another way to get genetically modified food into the home is to market the "harmonic oil" and soybean oil.
When buying oils, if you are very concerned about genetic problems, you can avoid soybean oil and rapeseed oil. It should be noted that due to the high fat content and low protein content of imported GM soybeans, it is suitable for oil extraction and is not suitable for tofu. The marketed soybean products are mostly domestically produced non-genetically modified soybeans. There is no need to worry about it.
Refrigerator is a kind of refrigeration equipment which keeps a constant low temperature, and also a kind of civil product which keeps food or other articles in a constant low temperature and cold state. There is a compressor or, ice maker for freezing cabinet or box, with refrigeration device storage box.
The characteristic of the products:
1 Ideal chemical inertia and can be widely used in various temperature-controlled heat dissipation occasions;
2 The low boiling point is a very moderate one. There is evaporation in the course of work, which take heat away through the heat of evaporation, thus ensuring the heating parts can work well and stably;
3 Non-dangerous goods, non-flammable and non-explosive, no fire point and flash point;
4 Good electrical insulation, extremely high breakdown voltage above 40KV;
5 The dielectric constant below 2 doesn`t make data lost in data center applications ;
6 Good fluidity, lower viscosity than clear water; Can flow well and dissipate heat in the temperature control system;
7 Nontoxic, harmless, non-irritating;
8 Environmentally friendly, have ODP value of 0 and extremely low GWP value
