How does rice become white? 

Rice becomes white by a series of processes involving the removal of husk, bran, and germ part of the rice.

To manufacture rice, firstly, the hand-pounding technique is used, in which a huge mortar and pestle type equipment is used before any mechanical technology, but if the mechanical technique is used, it can result in the generation of a large quantity of effort and capital. 

The husk, bran, and germ of rice are removed during the milling process. This method extends the shelf life of rice, however, it also removes the majority of the rice’s fiber, vitamins, and minerals.

What are different types of rice?

How can you store white rice for long-term use?

Below are given different methods for long-term storage of rice:

PET Bottles (Polyethylene terephthalate)

If you purchase rice per kilo, storing them will be easy. There are a lot of plastic bottles that are made from PET or Polyethylene terephthalate.

Soda bottles, jams, and even water bottles are made from PET. You can dry them out thoroughly and then put the excess uncooked rice inside. Moreover, keep them away from direct light for better and longer storage.

Mylar Bags with Oxygen Absorbents

Mylar bags are common food storage. It is made of a material called a clear ‘mylar’ that is laminated to an aluminum foil.

Mostly beans like coffee are sealed inside the mylar bags to avoid oxidation and seal in the freshness. They usually go along with oxygen absorbents to ensure the freshness and longevity of food.

Resealable airtight containers

If the above two options are not available, you can use any resealable containers as long as you ensure that the lids are secured and airtight. Some use plastic bags with locks and simply remove all the excess air inside by using a vacuum and store it away from direct light.

Buckets

Food-grade buckets are also safe to use when it comes to food storage. Simply add oxygen absorbents inside along with the rice and store them properly.
