What Is Glutinous Rice?
Glutinous rice is the sticky rice which is commonly used in Asian countries.
In Japan, it is used to make, for example, rice cakes (mochi), red rice (steamed rice with red beans), and mixed glutinous rice (okowa). Also, a Japanese sweet called ohagi (rice ball coated with sweetened red beans) made from glutinous rice is popular.
Glutinous rice has nice and chewy texture which is totally different from the regular rice. You must be going to be addicted to this amazing texture and taste.
There are actually various easy recipe that you can make those foods using glutinous rice at home these days. And, I think it’s difficult to use the surplus rice for those who bought it in a big bag. Some of them maybe say “when did I buy this glutinous rice?”.
Here, I would like to introduce glutinous rice shelf life, long-lasting storage method, what happens when it rots, and so on. Please check it out!
What Is the Shelf Life of Glutinous Rice?
The shelf life of glutinous rice is about a year to a year and a half after the rice is polished which is longer than the regular rice (non-glutinous rice). The polishing date is probably stated in most of the glutinous rice sold at grocery stores, so you should refer to it.
It is possible to eat after this period, by the way. Please check the following section.
Is the Shelf Life Different Between Unopened and Opened?
Usually, food has an unopened best-by date written on it. There is an image that you have to eat early when opened, regardless of the expiration date, right?
But, the expiration date of the glutinous rice is the same whether it is unopened or after opening. (Non-glutinous rice is the same thing.)
The reason is that there are already a lot of small holes in the bag containing rice because the outside air can go in and out.
According to the story of the rice maker, it seems that a hole is made in the bag to remove the air in order to prevent the bag from tearing due to the weight of the rice piled up during transportation.
Can You Use Glutinous Rice After Expiration Date?
The shelf life of glutinous rice is usually a year to a year and a half after the rice is polished. However, you can eat it for about 2 years after the expiration date has passed.
