How to store rice bran and how long can rice bran be stored

Most young people today don't know about rice bran. Only the older generation, who once relied on rice bran to get through difficult times, now even pigs won't eat rice bran. However, this kind of rice bran that people dislike actually contains extremely high nutrients and is a very beneficial food for the human body. However, how to preserve rice bran is a difficult problem. Let's take a look at how to preserve it.

How to store rice bran

1. Hot steam treatment

After being processed by hot steam treatment, the storage time of rice bran will become longer. This is because the high-temperature hot steam directly acts on the rice bran, which can have an excellent sterilization effect. However, this does not have a star effect on the passivation of lipase, resulting in its activity being more repetitive. This processing and preservation method is not perfect.

2. Hydrochloric acid treatment

The reason why rice bran deteriorates is that the activity of lipase is too strong, which easily attracts bacteria. Spraying hydrochloric acid directly on the rice bran can reduce its pH value. This acidic environment has an inhibitory effect on the activity of lipase, which can reduce the growth of bacteria. After treating the rice bran with hydrochloric acid, it can be stored for a longer time.

3. Extrusion processing

Practice has proven that puffed rice bran kills bacteria and microorganisms, and can also inactivate the activity of lipase to prevent it from being contaminated. Puffing rice bran and storing it in a cool and dry place can greatly extend the shelf life of rice bran.

How long can rice bran be stored?

Generally speaking, the storage time of rice bran is about ten days. If it exceeds this time, the rice bran will deteriorate. Eating spoiled rice bran will not only fail to play a health-care role, but also cause diarrhea and vomiting. If you want to store rice bran for a long time, it is best to store it in the above way, which can extend the shelf life of the rice bran.
