Apple cider vinegar powder is simply dehydrated cider vinegar. It is a convenient and easy-to-use substitute for liquid vinegar, although it can be reconstituted by mixing 1 part powder with 1.5 parts water.

The powder is used to add tangy flavor to salad dressings, marinades, sauces and BBQ rubs and seasoning blends. ACV powder is also used in the food industry as a preservative and flavoring agent in functional foods and drink mixes, and in the cosmetic industry for various skin care products.
