Frozen Vegetables are Poor In Nutrition?
Many people believe that the freezing and thawing process will destroy vitamins, and the nutrition of frozen vegetables and Frozen Fruits is definitely not as good as fresh ones. Is the nutrition of frozen vegetables really worse than that of fresh vegetables? The answer was unexpected—not necessarily.
When fruits and vegetables are picked from the tree, they are still undergoing biochemical activities such as breathing, and they are also degraded in the process. This is the law of nature. Before fruits and vegetables enter supermarkets and farmer's markets, they have to go through processes such as transportation and storage, and finally reach consumers' homes, often after a long journey. In this process, the nutrition of fruits and vegetables will also be lost.
Frozen Green Beans
As for frozen fruits and vegetables, once they are picked, they will soon be frozen at minus 18 degrees Celsius. At this temperature, the respiration of fruits and vegetables is almost stagnant, and microorganisms cannot grow and reproduce. Theoretically, the preservation of nutrients in fruits and vegetables by the freezing process is not harmful, but beneficial.
In view of the nutrients in common fruits and vegetables, such as vitamin C, B vitamins, polyphenols, carotenoids, etc., the US Department of Agriculture has conducted an investigation on the market. The results show that although there are differences in certain nutrients between frozen vegetables and fresh vegetables, there is no obvious difference overall; even, in some cases, the preservation rate of vitamin C, B vitamins, carotenoids and other nutrients in Frozen Vegetables and fruits , It is higher than fresh fruits and vegetables.
Scientists at Sheffield Hallam University in the United Kingdom found that there is not much nutritional difference between fresh food and frozen food after studying 37 products. The study also found that Frozen Green Beans and fresh green beans have higher levels of beta carotene after cooking.
For this reason, international health organizations believe that frozen fruits and vegetables and fresh fruits and vegetables are both healthy foods. The stereotype of "frozen fruits and vegetables are of poor quality" is outdated.
