Rice is the staple food of nearly half of the world's population, and people in many regions are accustomed to using rice to supplement their daily needs for calories, vitamins, proteins and some trace elements. In our country, rice is also one of the staple foods that every household must have. Friends who often buy rice should find that sometimes, the color of the rice bought at home will change, for example, if the storage time is too long, the color of the rice will be dark, and the storage place is too heavy with moisture, and there may be yellow grain rice or even carrot-colored rice. These are all color changes caused by improper storage, so can these rice that have changed color still be edible?In this issue, I will reveal the secret for you, can you still eat color-changing rice?
1. Causes of discoloration of rice.
There are three main cases of rice discoloration, one is dark color, no luster, and cracks in the skin, the other is that the rice grains are slightly yellow, and the third is more special, which is caused by mold, and the rice may be grayish-white, yellow or orange like a carrot.
1.The color is dull and dull.
The color of the rice is dark, there is no luster, the skin is cracked, and the rice becomes brittle, which is due to the fact that the rice is stored for too long, and the water in the rice grains volatilizes a lot, resulting in a change in the appearance of the rice, which will lead to the poor taste of the steamed rice, but there is no mildew, and it does not affect the consumption.
2.The rice is yellow.
When many friends buy rice in the supermarket, especially bulk rice, they will also find that there are a few yellowish rice grains in the rice, and some friends think that this is the normal color of rice, indicating that there is no excessive processing, and specially select this kind of rice that is slightly yellowish and similar in color to brown rice. In fact, this kind of rice is the color of yellowing caused by rainy weather when rice is harvested, and it is not dried in time, also known as yellow grain rice, this kind of rice is non-toxic and harmless, and the taste is the same as ordinary rice, but the color is slightly yellow, and this kind of rice can be eaten normally. However, this kind of rice is not dried in time, and has higher requirements for the preservation environment.
3.Discoloration caused by mold.
If the rice is not stored properly and placed in an environment with high humidity and temperature, the rice will be easily contaminated by molds during the preservation process, mainly including Penicillium citritica, Penicillium aeruginogenus, etc., which will produce toxic metabolites under suitable conditions, resulting in yellowing of rice, and gray-white, brownish-black mildew may also appear. In addition, the rice is carrot-colored rice, and everyone needs to be vigilant, which may be caused by aflatoxin contamination. This kind of rice caused by mold is not recommended for everyone to eat, it may cause stomach pain, diarrhea and may even contain carcinogens, which has a greater impact on health.
In general, when we store rice, we should pay attention to storing it in a ventilated, dry and cool place, away from light and high temperature, and when buying rice, we should do a small amount of rice many times, avoid storing rice for more than 3 months in summer, and not more than 6 months in winter.
