Herbal extract

An extract is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol or water. Extracts may be sold as tinctures or in powder form.

The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, and wintergreen.

The distinctive flavors of nearly all fruits, in the popular acceptance of the word, are desirable adjuncts to many food preparations, but only a few are practical sources of sufficiently concentrated flavor extract.

The majority of concentrated fruit flavors such as banana, cherry, peach, pineapple, raspberry and strawberry, are produced by combining a variety of esters with special oils. The desired colors are generally obtained by the use of dyes. Among the esters most generally employed are ethyl acetate and ethyl butyrate. The chief factors in the production of artificial banana, pineapple, and strawberry extract are amyl acetate and amyl butyrate.
