Frozen vegetables are frozen foods, which are small packaged foods made by processing fresh vegetables such as peppers, tomatoes, beans, and cucumbers at the lowest possible temperature and as fast as possible.
Many people think that frozen food is unhealthy, so they also think that frozen vegetables are not as fresh and nutritious as ordinary fresh vegetables. However, the latest research shows that the nutritional value of frozen vegetables is actually higher than that of ordinary fresh vegetables.
Once fruits and vegetables are harvested, nutrients are slowly degraded and lost. When most agricultural products are delivered to the market, they are not as fresh and nutritious as when they were just picked.
Sometimes, in order to facilitate long-distance transportation or maintain a good appearance, farmers will harvest fruits and vegetables before they are ripe, and the time for vegetables and fruits to develop complete vitamins and minerals will be reduced. Nutrients are no longer comparable to full ripe fruits and vegetables. In addition, fruits and vegetables will be exposed to a lot of heat and light during transportation, which will degrade some nutrients, such as the more fragile vitamin C and vitamin B1.
However, frozen vegetables are usually frozen at the peak of vegetable maturity. At this time, the nutritional value of vegetables and fruits is the highest, which can lock in the most nutrients and antioxidants, and retain the freshness and nutrients of vegetables without affecting the its flavor.
This processing method makes the water in the vegetables quickly form regular and fine ice crystals, which are evenly distributed in the cells, and the vegetable tissue will not be destroyed. . Quick-frozen vegetables are very convenient to eat, and there is no need to wash, cut, and thaw them indoors. Because most of the frozen vegetables have been steamed, and some may also be seasoned with salt, so they are cooked in a flash, and their taste, color and vitamin content are almost the same as those of fresh vegetables.
