Does crystal light go bad?

In this brief guide, we will discuss the following question, “does crystal light go bad?”, and other queries related to this topic.

Does crystal light go bad? 

Yes, crystal light goes bad and does expire. Crystal light contains many additives and artificial sweeteners. So with time those products lose their quality and may develop a bad taste and their color will change.

However, there is an expiry date stamped on the product which indicates that the product can last for about 3 years. So, check it before buying the product or before using it. Thus, after this expiry date, the artificial sweeteners added start losing their sweet effect.

Furthermore, consuming expired crystal light powder will not cause any health effects but its taste will not be the best. In addition, an unopened package of crystal light can last for about 3 years if stored appropriately.

How to store crystal light powder?

The best way to store your crystal light powder is to put your unopened bag in a cool, dry place, far from direct sunlight, and use it before the expiration date stamped on the product.

Moreover, make sure to use your opened crystal light powder within one month of opening. Also, it is better to store it in its original container. However, if you want to transfer the powder into another container, make sure it is well-sealed.

Because air and moisture can decrease its shelf life and deteriorate the texture of the product.

Does a crystal light drink need to be refrigerated?

Yes, crystal light drinks do need to be refrigerated in order to increase their shelf life and preserve their freshness for a longer time. So, in the fridge, the crystal light drink can last up to two weeks. Moreover, a cooled crystal light drink is more enjoyable.

However, crystal light powder does not need to be refrigerated. Because it is a dry product that does not contain water that enhances the chance of bacteria proliferating within. Also, moisture and humidity in the fridge might make the product bad.

Can you freeze crystal light?

Yes, it is extremely safe to freeze crystal light drinks. In the freezer, your drink can last for about six months. Once you decide to drink your crystal light, remove it from the freezer and thaw it in the refrigerator overnight.

Avoid putting it directly at room temperature in order to thaw it, because its taste might change. Moreover, crystal light powder should not be frozen, until you dissolve it in water.

How to tell crystal light powder has gone bad?

Many signs can tell that your crystal light powder has gone bad. So, first of all, check for the color of your product. If its color changes to brown or yellow, it is a sign of spoilage, so do not use it.

Moreover, once you open the crystal light powder container you might notice a bad and strange smell. So, it means that it is time to throw it away and buy a new pack. However, the smell of the crystal light powder goes bad especially when it is not stored properly.

Furthermore, if none of the previously mentioned signs were obvious and you already prepared your drink, you might feel that its taste changed and it has a bitter and sour taste which is a sign of the product’s spoilage.

One last sign is having clumpy powder. This might be a sign of spoilage. However, the powder will clump eventually once it is stored in a moist and humid place. So, in this case, it will be safe to be consumed but do not take the risk and use it.

Is crystal light a good substitute for water?

No, crystal light is not a good substitute for water, because it contains additives like food colorings and preservatives. Thus, excessive intake of these chemical products might not be safe. So, drink crystal light occasionally.

However, since crystal light contains artificial sweeteners it will not provide you with calories, and the ingredients of this drink are considered safe and approved by the FDA.

Is crystal light healthy?

Crystal light does not have bad health effects as long as it is consumed in moderation. However, crystal light does not provide you with calories nor with any other beneficial nutrients. Hence, it only provides you with sodium which can be consumed from other healthier sources.

Moreover, all the ingredients of crystal light are synthetic. The reason behind not having any calories is the addition of an artificial sweetener called aspartame.

Despite being considered safe by the FDA, there are no long-term studies and evidence that support the hypothesis that aspartame is safe for long-term consumption. In addition, aspartame is forbidden for people suffering from phenylketonuria.

As well as forbidding the consumption of this type of drink for people having phenylketonuria, pregnant women should not be consuming crystal light. Because it was not proven yet its safety during pregnancy.

Also, food colorings were found to be linked to allergic reactions and hyperactivity in children.
