    When the temperature is high and the humidity is high, the taste of the rice will drop rapidly.

    Especially during periods of frequent rainfall, rice is prone to mildew.

    Many families will choose to keep their rice in the refrigerator for preservation.

    to avoid insects and mold in the rice.

    Not really. Rice can be stored at room temperature and does not need to be stored in the refrigerator.

    There is nothing wrong with this, because the refrigerator is a low-temperature environment, which reduces the activity of the enzymes and also inhibits the normal "respiration" of the rice, which reduces the oxidation reaction of the rice.

    So that the rice is not so easy to spoil.

    However, it is rumored that when rice is placed in the refrigerator, it is prone to a type of aflatoxin called aflatoxin.

    This substance can easily induce cancer after entering the human body.

    of the appearance. In fact, rice is indeed susceptible to various mold infections, but if it is kept in the refrigerator, mold activity will also stop, including aflatoxin.

    From a scientific point of view, mold is at 20 degrees Celsius.

    In fact, it has already begun to decrease a lot, and when it reaches 10 degrees Celsius, it will basically stop moving. The temperature in the refrigerator is about 3-5 degrees Celsius, and in this low temperature environment, it is difficult for aflatoxins to move and multiply quickly, so it is impossible to contaminate the rice.

    Because rice should not be stored at the same time as fish, meat, vegetables and other foods with high moisture, otherwise it is easy to absorb water and cause mildew; Therefore, although it is a good practice to store rice in the refrigerator, the operation method is not right, which is more unfavorable to the preservation of rice.

    In addition, rice storage should not be placed directly on the ground, and should be placed on a dry, ventilated and clean pad; It is taboo to store food with high moisture indoors at the same time, otherwise it is easy to absorb water and cause mildew; Families taboo rice storage in the kitchen because the kitchen temperature is high and the humidity has a great impact on the quality of rice.

    The shelf life of rice.

    Rice hulling is the same as losing the umbrella, so rice spoils faster than rice. Generally, the rice produced by milling is produced after 1 week.

    The fatty acid value of rice will increase significantly.

    In the past, the living conditions were not good, and we could not eat fresh rice at any time, and every household developed the habit of tun rice, which was actually very unhealthy.

    In general, the shelf life of bulk rice is 3 months in spring and summer, and 6 months in autumn and winter; Embryo rice.

    The embryo is easy to deteriorate, and the shelf life is 1 month; The shelf life of rice that has been polished to form a protective film can be extended; Vacuum packaging also extends the shelf life of rice. Therefore, the rice you buy home should be eaten within 1 month as much as possible. So try to buy vacuum-packed rice!

    Vacuum-packed rice.

    Oxygen that comes into contact with the rice is completely blocked.

    This prevents oxidation of the rice.

    This is a vacuum-pumped, individual packet.

    Let the rice be as fresh as if it had just been polished.

    Because the more time passes, the more moisture forms on the surface of the rice, which slowly penetrates the rice, and then takes it out of the refrigerator and when it thaws, it will naturally become powdery.

    Generally speaking, rice can be frozen in the refrigerator, but it cannot be frozen for a long time, otherwise the nutrients in it will be reduced and the taste will also decrease. If you want to preserve rice, it is recommended to send it to the refrigerator freezer in batches and freeze it for 24 hours, so that it will not be easy to get insects in the summer after it gets used to the cold. Rice is not recommended to be frozen in the refrigerator, which will affect the quality of the rice, we can put it in a plastic bag, and then put it in the refrigerator fresh-keeping layer for preservation, or put it in some dry and ventilated places, which can also extend the shelf life.

    Well, freezing is indeed effective, my rice has been frozen for about three days after being wormed, it will not be powdered, and the taste will not change much, which is still very useful.

    Before freezing, my daughter-in-law used a cardboard box with sugar to put it next to the rice bag for a few days to attract the insects out before freezing, so that there would be a lot fewer insects in the rice, and if the insects were just born, they could even attract most of the insects.

    But if the rice is a big bag. It is best to freeze it. If the refrigerator is frozen, one is that there may not be enough space, and the other is that the refrigerator often puts some meat and fish and the like, and the rice will smell when it is placed, so it is best to wash it carefully before freezing.

    How can the frozen rice be powdered, the rice in the Northeast is not minus twenty or thirty degrees in winter, it is not just like that, I have not heard of it being powdered as soon as it is frozen.

    It only takes more than four hours for frozen rice to freeze the bugs to death. Frozen rice will not be powdered, and the taste will not be affected. The premise is that you can't get wet.
