The United States Department of Agriculture’s Food Safety and Inspection Service suggests that it is perfectly fine to freeze any type of yogurt in air tight containers or placing the serving-sized cups in thick plastic bags to preserve it and prolong its shelf life.

Another very popular type of yogurt is Greek yogurt. It is a healthy snack and also a part of many recipes. Many popular chefs and food bloggers will also authenticate the fact that it is perfectly fine to freeze Greek yogurt; it is known to extend the life of the yogurt by at least a month. A cup of yogurt that is thawed may have some change in its texture and taste.

What Happens When You Freeze Yogurt?

When the yogurt is frozen, the bacterial activity becomes somewhat dormant, except for the cryogenic bacteria if they are present. However, that is not the case with thawed foods. On the whole, one should be careful with foods that are thawed because they may not remain fresh and edible.

Thawing is the stage when the bacteria become active and when the yogurt is kept at room temperature, it is likely to be infested by outside bacteria if not thawed under the right conditions…

How to Freeze Different Types of Yogurt?

Whether it is a homemade, Yoplait, or Greek yogurt, both the freezing process and the consumption process remain more or less the same.

If yogurt cans or cups are unopened, you might risk the cup bursting in deep freeze as the yogurt may expand. Placing the cups in airtight zip-lock bags prevents the yogurt from overflowing in case the cup does burst and it also prevents the yogurt from picking up odor from other stuff in the refrigerator. Meat and fish are popular candidates to pass on their odor to other items.

Another idea to ensure equal and homogeneous freezing is to open the cup, stir the contents with a spoon and then reseal it with a cling wrap or aluminum foil. Take out from the freezer as needed and thaw in the refrigerator for a couple of hours.

Mix or stir it again before eating to get the same taste as before.

How Does Freezing Affect the Quality of Yogurt?

If frozen properly, the quality of the yogurt is not affected. However, some of the yogurt may separate when thawed. It is, however, still perfectly fine to consume. A little stirring to make the mixture homogeneous again can help to bring the texture back to its original form.

A thawed out yogurt cup may also cause the yogurt to become grainy and watery. As long as the grainy structure does not bother you; even this yogurt cup is good to consume. It is critical to note that if the yogurt remains outside the refrigerator for more than two hours after thawing, it may not be consumable and should be discarded.

Effect of Different Supplements on Frozen Yogurt

A number of studies have been conducted to check if any supplements can be added to improve its texture, life, and nutrients. Consuming yogurt that has probiotic culture added to it is known to improve digestion because of the friendly bacteria in it.

An independent study conducted jointly at the University Of Washington, USA and the University of Agriculture, Pakistan studied the effect of adding supplements like inulin and glycerol in probiotic frozen yogurt.

Inulin, a Healthy Addition to Yogurt

Inulin is basically a carb, a type of dietary fiber or polysaccharide produced by certain plants. So, it helps with regulating metabolism, bowel movements and may aid in managing weight. Some research conducted by the Department of Health and Nutritional Sciences at the University Of Guelph, Canada, says that inulin, when added to yogurt and eaten for breakfast, helps reduce post-prandial appetite without dropping the energy levels. So the goodness of yogurt along with all its protein content plus inulin seems an extremely healthy combination.

When certain quantities of supplements were added, the overall quality and certain physical, as well as chemical properties of the frozen yogurt, improved. The softness as well as overrun could be controlled and changed to suit the preference of the consumers.

Details of another study also focused on the addition of inulin as a supplement. It was seen to improve the overrun, viscosity, and melting properties of yogurt significantly.

You can add your own supplements to your homemade yogurt in the form of fruits. That will also make it rich in fiber and other nutrients present in the fruits along with protein content in the yogurt. However, make sure to eat it fresh; avoid freezing it as much as you can.

How Long Can You Freeze Yogurt?

When we take the proper precautions to freeze yogurt, it can easily last for months. And sometimes even for upto three weeks beyond its use by date. Here is a quick summary of how much it lasts when opened and unopened:
