The nutritional value of freezing tenderstem broccoli is higher than that of ordinary vegetables, not only that, but also particularly comprehensive nutrition. According to research by scientists, broccoli has anti-cancer abilities. Long-term consumption of broccoli can improve the body’s immunity. Fresh broccoli has poor storage, and it can be eaten within 4 days, cold or boiled. Freezing tenderstem broccoli can be stored for more than half a year.
Broccoli can be frozen because its shape allows harmful bacteria to multiply inside, causing it to rot and turn yellow, and low temperatures can inhibit bacterial growth and prolong its shelf life. You can also use newspaper or plastic wrap. Then put the package in the refrigerator so that it is not easy to cause deterioration and the color will not turn yellow.
The normal temperature preservation method for broccoli is to either wrap it completely or place it in a very dry, cool, and ventilated place so that the broccoli will not turn yellow and the color will remain green, or it can be broken and cleaned. Then put it in a pot to scald, take it out and soak it in cold water for a few minutes to control the moisture, put it in a plastic bag, and put it in the refrigerator.
Freeze or refrigerate
Whether broccoli should be refrigerated or frozen depends on different perspectives. The low temperature of the refrigerator is more suitable for the storage temperature of broccoli, which will not destroy the nutrients in it, but the storage time will be shorter. From the perspective of storage time, freezing tenderstem broccoli can be stored for a long time, but because the temperature is too low, the nutrients in the broccoli will be lost to a certain extent.
Nutritional value of freezing tenderstem broccoli
Freezing tenderstem broccoli has high nutritional value and contains a variety of minerals, vitamins, as well as protein, carbohydrates, fat, dietary fiber, etc.
Freezing tenderstem broccoli is rich in dietary fiber, which can promote gastrointestinal motility, thereby promoting defecation. Proper consumption of broccoli by people with poor bowel movements can improve the problem of difficult bowel movements.
Freezing tenderstem broccoli contains very comprehensive minerals, such as calcium, phosphorus, iron, potassium, zinc, manganese, etc., which are relatively rich. Eating broccoli can supplement various minerals needed by the human body, which is beneficial to enhance the human immune system.
Freezing tenderstem broccoli contains various vitamins such as vitamin A and vitamin C, especially the content of vitamin C, which is relatively high. Vitamin C can scavenge free radicals in the human body, promote liver detoxification, and benefit the growth and development of the human body.
Freezing tenderstem broccoli also contains a component called dithiophenol thione, which can reduce the enzymes that synthesize melanin, prevent the formation of skin pigmentation, and thus play a whitening role.
How to freezing tenderstem broccoli
Remove the impurities and damaged parts around the broccoli, then spray some water on it, wrap it with white paper, and finally put it in the refrigerator to refrigerate. When storing the broccoli in the refrigerator, ensure the permeability of the broccoli, do not store it in a sealed container, and ventilate it so as not to cause the broccoli’s own nutrients to interact and deteriorate.
Under the low temperature conditions of the refrigerator, it can help to inhibit the damage of bacteria and other harmful substances to the broccoli, and it can also keep the broccoli fresh. Therefore, under the low temperature condition of the refrigerator, the broccoli can be stored for about 4–5 days.
Wrap the broccoli in a damp paper towel. This method imitates the automatic water supply device in the supermarket, which can also play a role in preserving freshness. Start by filling a clean watering can (not one that has previously been filled with bleach or other cleaners that contain caustic chemicals) with water, then lightly spraying some of the broccoli heads. Gently wrap the head of the broccoli with a paper towel, allowing the paper towel to fully absorb excess moisture. Finally, put the broccoli in the refrigerator. This will keep for about 3 days.
Put the broccoli in a breathable bag for preservation. If you don’t have the time or patience to preserve your broccoli using the above methods, here’s a lazy but effective way to store your broccoli in a regular plastic bag. All you need to do is seal the broccoli in a plastic bag and poke a few holes in the plastic bag near the head of the broccoli to allow for good airflow. Finally, put the broccoli in the refrigerator. This storage will also keep the broccoli fresh for a few days.
Raise broccoli like flowers. This approach may be a bit unconventional, but it works surprisingly well. As long as broccoli is fed like a flower, its fresh-keeping period can be greatly extended. All you need to do is place a broccoli head-up and stem-side down in a bowl and fill it with about 0.7 cm of water. Note that the head must be facing up and above the water surface. Finally, put the broccoli in the refrigerator. This method can extend the shelf life of broccoli to 5-7 days.
