What’s Mochi?

If you haven’t heard of mochi before, it is a sort of sweet rice cake that originated in Japan but has become popular all over the globe. If you haven’t heard of mochi before, we will explain what it is.

Since the eighth century, people have been using it.

Mochi may be found in a variety of sizes, shapes, and tastes, including sticky cakes, which are square-shaped mochi that are flat on one side, and circular mochi balls.

The sticky and chewy consistency of mochi is one of the characteristics that contributes to the dish’s indelible reputation.

The chewy texture is a result of the use of japonica short-grain glutinous rice in the preparation of the product.

Despite the fact that it is customarily served on New Year’s Day, it is also consumed at other times of the year as a topping for soup or a snack.

Mochi is a delectable treat that also has a number of health advantages to offer.

As a sweet treat, mochi is beneficial to your health due to its low cholesterol and saturated fat content.

In addition, it is an outstanding source of Vitamins A, C, E, and K, as well as Phosphorus, Niacin, Calcium, Folate, Magnesium, Riboflavin, Manganese, and Iron, which makes it an outstanding choice for a snack.

How Long Does Mochi Last? Does Mochi Go Bad?

The quality of the storage determines how long mochi will remain edible. The length of its shelf life changes depending on whether it is kept in the refrigerator or the pantry.

  • Shelf life in Pantry.

When kept in the pantry, mochi has a rather limited shelf life.

If you leave mochi in the pantry at room temperature, it will remain fresh for one to two days, depending on how warm and humid the environment is where you reside.

The only way to ensure that your mochi will remain edible for more than two days is to keep it in the refrigerator.

  • Shelf life in the fridge .

Mochi has a shelf life that is significantly extended when it is kept in the refrigerator.

Its shelf life may be extended to between 7 and 14 days if it is refrigerated.

If the mochi has been stored in the refrigerator for more than 14 days, you should toss it out since there is a great likelihood that it has gone bad.

  • Can Mochi be frozen?

If you want your mochi to have a longer shelf life, storing it in the freezer is the way to go.

The following contains information about how long handmade mochi, mochi purchased from a shop, and mochi created professionally may remain fresh when they are frozen.

Mold may easily spread through homemade mochi. Because of this, you need to put it in the freezer as soon as you can.

If you put the mochi in the freezer, it will remain edible for about a month after you have done so.

Mochi that is purchased will have a longer shelf life. Therefore, you need to make sure that you examine the paper that is on the container to get information about the cake’s expiration date.

When kept at room temperature for a few months, mochi that was prepared commercially and sealed in an airtight container maintains its flavor and texture.

It may maintain its quality for up to a year if you store it in the frozen compartment of the refrigerator.

After being opened, mochi may be kept fresh in the refrigerator for one week, or in the freezer for up to two weeks. Both of these storage methods are recommended.

How to Tell if Mochi is Bad?

You have to examine any mochi that you have stored in your cupboard or refrigerator before consuming them or offering them to any of your visitors.

Mochi that isn’t made properly may make you, your family, and any visitors that you have ill.

Whether you want to know if your mochi is spoiled, look for the indicators that are listed below.

  • Mold .

Mold on the mochi is the most typical indicator that it has gone bad.

If you leave mochi out in the open at room temperature for a lengthy period of time, it will get moldy.

On a mochi, the presence of red or blue mold is not hard to see.

It’s possible that you’ve considered scraping off the mold and eating the mochi.

However, due to the mold’s pervasive presence throughout the mochi, doing so might potentially get you ill.

Because mold produces chemicals that may make you ill, you should avoid eating mochi that has been tainted by mold.

  • Change of color .

The surface of the mochi will become pink or milky white as it begins to rot.

If the outer layer of the mochi begins to become a different color, you should toss it aside.

  • Bad odor .

By giving a mochi a whiff, you can determine whether or not it is of high quality.

If the mochi smells like something that has been fermented, there is a very high chance that it is spoiled.

I beg you, do not consume it; rather, toss it.

  • Change in text and taste.

If the mochi is too dry to eat, this is another indication that it is not good.

If you don’t cover the rice cake before placing it in the refrigerator, the top layer of the cake will rapidly get dry.

Last but not least, you should throw away the mochi if it stops having a chewy and elastic texture and instead becomes hard and flavorless.


In conclusion, mochi is considered an exquisite food not only in Japan, where it was first developed, but also all across the rest of the globe.

If you have any mochi left over, you may be unsure whether you should save it or throw it away. Here’s a look at both options.

It is essential to have some idea of how long mochi will keep and whether or not it will spoil.

You should put mochi that will be used in the next one to two days in the pantry so that it is stored properly.

If you put any mochi that you won’t be eating shortly in the refrigerator, you may get an additional 14 days of use out of it.

Before you consume it, do a mold inspection to make sure it is free of the fungus and is still safe to eat.
