Yes you can freeze the chicken base.
Just place the chicken base in a freezer safe container and then place it in the freezer.
The chicken base will last in the freezer for up to a year but it's best to use the chicken base before 6 months for the best taste.
The longer the chicken base stays in the freezer the less tasty it becomes but it remains safe to use and eat.
Chicken base is used in recipes such as soups, stews and sauces.
The main purpose of chicken base is to add flavor to soups, stews, sauces etc.
You can make the soups, stews, sauces etc without chicken base but if you make the soups, stews, sauces etc with the chicken base it will have a much better flavor.
You can get chicken base in powder form or in liquid form.
Adding chicken base to your recipes helps add some good flavor to the food you're cooking and makes it more enjoyable and more tasty.
I always just use the powder based chicken base to add to the food.
