To freeze yogurt starter, make sure it’s in a clean, airtight container. You can use a small freezer-safe plastic container or ice cube trays for individual portions. Fill the container leaving a small space at the top to allow for expansion as the starter freezes.
Yogurt Starter: What is it and How to Store it?
Yogurt starter is a key ingredient in making homemade yogurt. It is a specific combination of live bacteria cultures that are responsible for fermenting the milk and turning it into creamy, tangy yogurt. These cultures include Lactobacillus bulgaricus and Streptococcus thermophilus, which work together to convert lactose into lactic acid.
If you want to make yogurt at home, you’ll need to get your hands on a yogurt starter. This can be obtained in the form of a powdered starter culture or by using a store-bought plain yogurt with active cultures as a starter.
Once you have your yogurt starter, it is important to store it properly to maintain its potency. The best way to store yogurt starter is in the freezer. Freezing the starter suspends the bacterial activity and allows it to remain dormant for an extended period of time.
To store yogurt starter in the freezer, follow these steps:
- Transfer the yogurt starter into small airtight containers or ice cube trays.
- Label each container with the date of freezing to keep track of its freshness.
- Place the containers or ice cube trays in the freezer, ensuring they are tightly sealed to prevent freezer burn.
When properly stored in the freezer, yogurt starter can last for up to one year. However, it is recommended to use the starter within three months for optimal results.
Pro tip: Before using frozen yogurt starter, allow it to thaw in the refrigerator overnight. This will ensure that the bacteria cultures are reactivated and ready to ferment the milk.
In conclusion, yogurt starter is an essential component in making homemade yogurt. By properly storing it in the freezer, you can extend its shelf life and continue to enjoy delicious homemade yogurt for months to come!
