"Other than as a food, beets have use as a food coloring and as a medicinal plant... A large proportion of the commercial production is processed into boiled and sterilised beets or into pickles. In Eastern Europe, beet soup, such as borsch, is a popular dish. In Indian cuisine, chopped, cooked, spiced beet is a common side dish."

Beet extract prepared by steam distillation to evaluate the volatile components yielded a base fraction with potato-like odor and a neutral fraction with distinct earth-like odor, leading to a single compound, geosmin (known as product of soil-organisms of the order Actinomycetes). \\ | Beet extract prepared by steam distillation to evaluate the volatile components yielded a base fraction with potato-like odor and a neutral fraction with distinct earth-like odor, leading to a single compound, geosmin (known as product of soil-organisms of the order Actinomycetes). \\ | ||
