As the saying goes: garlic is afraid of moving and freezing. In other words, garlic should not be moved often (which is why fresh garlic should be patched up and hung up), but garlic, like onions, is not afraid of freezing.
Changes of garlic freezing;
1. Garlic can be eaten in the cold room without spoilage. Although the storage temperature of garlic is not below zero, garlic will not change its nature and taste in a short time. If the time is too long, some changes may occur. If the quality of garlic itself is not good, it is probably inedible.
2. Garlic should keep its intact shape after freezing. If it is frozen rot, it is likely that garlic itself is of poor quality and easy to deteriorate. Therefore, eating garlic is not recommended. What happens when garlic is frozen?
3, garlic in the freezer for a long time, some effective ingredients will be oxidized, leading to yellowing. When garlic is put into the freezer, it will evaporate some water, which will lead to the decrease of garlic water content. Garlic frozen for a long time will have a special garlic flavor for a long time, which will affect the taste of garlic. Changes in nutritional components Some easily oxidized vitamins and other components will be oxidized, resulting in decreased nutrition.
4. Frozen germinated garlic can also be eaten. In the germination process of garlic, some antioxidant effects are much stronger than those of ungerminated garlic, and the effect of sterilization and cancer prevention after eating is better; Only protein, carbohydrates, selenium and other mineral elements will be consumed, but will not produce toxins, so you can eat frozen garlic.
Extended data
There are many ways to store garlic. According to the storage purpose and conditions, hanging storage, stacking storage, burial, radiation storage, chemical treatment storage and other methods can be adopted. Details are as follows.
① Hanging storage method: When garlic is harvested, it is necessary to strictly select the garlic that is hung and stored, remove the garlic that is too small, rotten, damaged and damp, and then spread it on the ground to dry until the stems and leaves become soft and yellow and the garlic skin is dry. Finally, 50- 100 pieces of garlic with the same size were woven and hung under a cool, ventilated and rainproof eaves to dry and preserve.
② Stacking method: After garlic is harvested, garlic with loose petals, moth-eaten, mildew and injury should be removed to avoid rain rot. A week or so, and then the second yard. Repeat this twice to dry all garlic, then transfer it to a ventilated place indoors, pile it in a storage room or bamboo basket, keep it in a low humidity and cool condition, and check it frequently.
③ Burying method: the width of burying ditch is1~1.5m. After garlic is buried, it can't be checked at any time. In order to avoid decay and loss during storage, garlic without disease and damage should be strictly selected for storage before burial. Generally, chaff is used as a covering for garlic burial. First, lay a layer of 2 cm thick chaff on the bottom of the ditch, and then pile garlic layer by layer until it is about 5 cm above the ground. Covered with chaff, garlic is not exposed to the air, resulting in a certain sealing condition, which inhibits the respiration of garlic and reduces the oxygen content, which is beneficial to the deposition of carbon dioxide in the storage environment and is suitable for garlic storage.
④ Radiation storage: Radiation treatment is to irradiate garlic with gamma rays with lethal dose of 14000 roentgen. When irradiated, water and other substances in garlic will be ionized by R-rays passing through bulbs, producing free radicals or ions, thus inhibiting metabolism. The method has simple operation and high fresh-keeping quality, and can be stored at room temperature for about 1-2 years.
⑤ Treatment and storage of chemical agents: Qingxin is the commonly used chemical agent, and its sodium, potassium and ammonium salts are easily soluble in water and have low toxicity to people and animals. The method is: bolting garlic until one week before harvest, adding 120 to 180 times of water to dilute and spraying on garlic leaves to inhibit garlic germination. The sprayer for spraying medicine should be cleaned after use, and be careful not to spray garlic seeds, so as not to affect germination.
