Can you freeze yogurt?

In this brief article, we will answer the question, “Can you freeze yogurt?” and tell you what would be the consequences to its properties by doing so.

Can you freeze yogurt?

Yes, you can freeze yogurt, who doesn’t like a fresh yogurt popsicle in the middle of the summer, but if it’s not your case, well, by freezing yogurt you may increase its shelf life for a few months, but maybe once it melts, its texture may not be the same.

When freezing yogurt, all its components crystalize, and some of them may get their structures broken, making them more fragile when restored to room temperature, and you may see that it seems milkier with water.

Nonetheless, melted yogurt may not represent any risk to your health if you take it to room temperature in adequate conditions, that is, taking it from the freezer to the fridge, and not leaving it at room temperature, because at room temperature bad bacteria may also grow in the yogurt (1) 

Does freezing yogurt affect its nutritional properties?

Freezing yogurt may affect its nutritional properties, most of the nutrients in food are affected by freezing, but certainly, it would depend on the time that you keep your yogurt frozen. In fact, freezing is a good way to increase the shelf life of food and maintain some of its nutritional properties (2).

When you freeze a yogurt the components that are responsible for the loss of nutrients and the original structure of the food, like enzymes or biochemical processes, are diminished, nonetheless, the sole effect of freezing has been demonstrated to reduce the properties of nutrients.  

The loss of nutrients by freezing doesn’t mean that now you don’t have to freeze any food, sometimes it’s necessary, and increasing the shelf life of the product with a slight decrease in its nutritional properties, surely is best instead of wasting the product (3).

Also freezing is not perfect in all ways, you may see that when a frozen yogurt melts, it certainly will not look like it before, that’s because the water in the yogurt crystalizes, also some carbohydrates and proteins may alter its structure, making the yogurt once melted lumpy (4).

Do live bacteria die when yogurt is frozen?

Live bacteria in yogurt may die when it is frozen, most of these beneficial bacteria are susceptible to freezing (5), but that doesn’t mean that you wouldn´t be able to consume it, in fact, the concentration of live bacteria in yogurt may be very low even before freezing (6).

Even if it’s true that we own yogurt to the friendly bacteria that ferment milk, it’s also true that for getting a health benefit from its consumption the bacteria must be in adequate amounts ( 1×109 UFC), but that is something that most yogurts don’t have (7).

Getting a benefit from yogurt consumption may rely more on its nutritional properties rather than the presence or absence of live beneficial bacteria, also when the bacteria ferments the milk those friendly buds before passing away, leaving some bioactive compounds like fatty acids, that enhance the nutritional properties of yogurt (8).

How long does yogurt last in the freezer?

Yogurt may last two months in the freezer, with barely losing nutritional properties, also two months is the period of time recommended for keeping it in the freezer according to the FDA (9).

Remember that you may take frozen yogurt to room temperature by taking it to the refrigeration temperatures near 4°C, or you can also wait one or two hours, and take a spoon and start scraping a delicious yogurt frappe.
