Now Foods Citric Acid, 1 lb (Pack of 1)

If you're into sprouting then you're already familiar with Citric Acid, a natural preservative typically found in citrus fruits such as lemons and limes. Citric Acid helps to inhibit the formation of mold and other bacterial growth, an all-too-common occurrence when sprouting in a jar due to high temperatures and humidity. Citric Acid is also useful for canning vegetables and fruit preserves.
