Gastrointestinal growth hormones, also known as fruit expanders, are now widely used in agriculture. Therefore, many of the fruits we see on the market are particularly large and their colors are particularly bright. If the use of gastrointestinal growth hormones exceeds the standard, it will cause the fruits to have various strange shapes, or some fruits to grow abnormally. When we eat fruits that have been injected with gastrointestinal growth hormones, it will cause some harm to our body. Bulking hormone It belongs to a type of plant growth regulator. It has the functions of accelerating cell division, promoting cell enlargement, differentiation and protein synthesis, increasing fruit setting rate and promoting fruit enlargement. Commonly used ones are chlorpyrifos and gibberellic acid. These are plant growth regulators allowed for use by my country's Ministry of Agriculture. They can be used on fruits such as watermelon, grapes, and kiwifruit to improve the growth state and quality of the fruit. For example, the "enlargement agent" is used for kiwifruit mainly to regulate its growth and prevent physiological fruit drop. Generally, 20 to 25 days after the kiwifruit blooms, the young fruit is immersed in 10 to 20 mg/L of solution for 30 seconds; 10 to 15 days after the grapes bloom, the young fruit is immersed in 10 to 20 mg/L of solution to increase the fruit set rate, enlarge the fruit, and increase the weight of a single fruit; spray 10 mg/L of solution on picked strawberry fruits or soak the fruits, and pack them in boxes after they are slightly dry, which can keep the strawberry fruits fresh and extend the storage period; during the physiological fruit drop period of navel oranges, 2 mg/L of solution can be used to apply to the fruit stalks to inhibit fruit drop. Are bulking agents harmful to the human body? Experts explained: "Both chlorfenapyr and gibberellins are low-toxic pesticides. There is currently no scientific evidence that these substances remaining on the surface of fruits and vegetables can cause harm to human health. Therefore, many developed countries such as the United States and Japan have listed "enlargement agents" as exempt substances that do not require toxicity management, and their residues do not need to establish safety limit standards. Therefore, it is safe to use "enlargement agents" on fruits and vegetables. It can even be understood that the risk of excessive use of "enlargement agents" is not harm to human health, but to reduce the quality of the fruit." There are also some ways to identify fruit with growth enhancers circulating on the Internet: "If fruits are super large and their colors are bright and look fake, they are usually grown with growth enhancers," experts say. This statement is also inaccurate, as the size and color of fruits vary greatly among varieties. For example, the fruits of polyploid varieties are usually much larger than those of ordinary diploid varieties. In addition, different environmental conditions have a great impact on fruit quality. Temperatures and differences in water and fertilizer supply can also cause fruits to differ in shape and size. Therefore, size and color alone cannot be used to identify whether a fruit has been grown with growth enhancers. If you see super large or deformed fruits, you can only say that "growth enhancers" may have been used, but you cannot be sure that it is "growth enhancer fruit." |
