Abstract: This application provides an arecoline salt and a preparation method and a product thereof. The arecoline salt is a benzoate of arecoline, with a structural formula shown as follows: where X is a molar ratio of arecoline to benzoic acid. The arecoline salt, with good physicochemical stability, is convenient to use and widely used.

Abstract: This application provides an areca nut-flavored product, containing an arecoline salt. Because an arecoline salt is used in the product, a user absorbs arecoline when consuming the product, and an effect similar to chewing areca nuts is produced, with relatively little irritation.

Abstract: This application provides a composition and a product thereof. The composition includes arecoline and an acid. The composition is convenient to use and widely used, with a low pH value and weak irritation.
