What is the reason for the yellowing of rice, the reason why the rice is yellow

Due to its high moisture content, rice is contaminated by a variety of molds during storage, and molds multiply in large quantities under suitable conditions and produce toxic metabolites, causing rice to turn yellow. It is recommended that you buy rice in small quantities and store it in a dry and ventilated place. In the north, rice can be stored for 3-6 months, and in the south it can be stored for no more than 3 months.

Due to its high moisture content, rice is contaminated by a variety of molds during storage, and molds multiply in large quantities under suitable conditions and produce toxic metabolites, causing rice to turn yellow. It is recommended that you buy rice in small quantities and store it in a dry and ventilated place. In the north, rice can be stored for 3-6 months, and in the south it can be stored for no more than 3 months.

After harvesting the rice, it cannot be dried in time due to rain. Storing the wet grains together will cause the rice to turn yellow. Yellow rice is also yellow and is called yellow rice. Yellow rice is generally not toxic, but its nutritional value and quality are inferior to white rice, and it is also prone to contamination with mold under the right conditions.

It is best to buy rice in small quantities and store it in a dry and ventilated place. In the north, rice can usually be stored for 3 to 6 months, while in the south, it is best not to exceed 3 months.

There are two different situations that cause rice to turn yellow, one is yellow grained rice, which is due to the fact that the rice is not dried in time after harvest due to rainy weather, and the wet rice is piled together, or it is not properly ventilated when storing rice, which causes the rice to heat up and turn yellow; The second is yellow-grained rice, which is caused by the color reaction of the nutrients in the rice.

Why does rice turn yellow.

Although the yellow grain rice has turned yellow, it does not carry bacteria in it, but it will be worse than ordinary white rice in terms of nutritional value, and it is also easier to breed mold in the adapted environment, so it is recommended to check carefully when buying.

The yellowing rice contains a variety of toxins, these toxins are a mixture of microbial toxins with similar structure, also known as aflatoxin, mostly formed under high temperature and high humidity conditions, according to research, it has clear carcinogenicity, and even causes chronic poisoning, which is extremely harmful to health.

It is recommended not to buy too much rice at one time, a small amount of rice can be used many times, and it should also be stored in a dry and ventilated place. The weather in the south is warm and humid, and it is best not to store rice for more than 3 months, if it is in the north, it can generally be stored for 3-6 months.

The reasons why rice turns yellow are:

1. One is that due to the high moisture content of rice itself, it is easy to be contaminated by molds such as Penicillium indicis, Penicillium citrics, Penicillium aeruginogenus, etc. during storage, and after that, the mold multiplies in large quantities under suitable conditions and produces toxic metabolites, causing rice to turn yellow, which is also known as yellow-turning rice. Yellow-turned rice contains a variety of toxins, which can cause liver lesions, and some can also cause kidney and nerve damage, which has a strong carcinogenic effect.

2. After the rice is harvested, it is dry when it fails to reach the reputation due to rain, and the wet grain is piled together for storage, which will also cause the rice to turn yellow. The rice milled from this yellowed rice is also yellow in color and is called yellow-grained rice. Yellow-grained rice is generally not toxic, but its nutritional value and quality are worse than that of white rice, and it is also easy to contaminate the mould of the sedan clump under suitable conditions.

It is best to buy rice in small quantities and store it in a dry and ventilated place. In the north, rice can generally be stored for 3 to 6 months, and in the south, it is best not to store it for more than 3 months.

The yellowing of rice is caused by moisture in the rice.

Rice is easy to be contaminated by mold during storage, and mold will multiply in large quantities under suitable conditions and produce toxic metabolites of acacia abohydrate, which will cause rice to turn yellow, and this kind of rice is also called liquid loss yellow rice.

How to store rice:

When buying rice, it is necessary to do small quantities many times and store it in a dry and ventilated place. In the north, rice can generally be stored for 3 to 6 months, and in the south, it cannot be stored for more than 3 months. When storing rice in a household rice tank, dry the container thoroughly before filling it in and cover it with a lid.

The amount can be bottled in a cola bottle, placed in a dry and ventilated place, and avoid high temperature and light.
