grapefruit juice

Grapefruit juice is the citrus-flavored liquid expressed from fresh pulp of Citrus paradisi, widely used as a flavoring and cosmetic ingredient.

General Material Description

Grapefruit juice, derived from the fresh pulp of Citrus paradisi in the Rutaceae family, is a liquid notable for its characteristic citrus odor and flavor. Known also as citrus paradisi juice or by various trade names such as Extrapone Grapefruit and Extrapone Pink Grapefruit GW from Symrise, this juice is a natural extract presenting sensory qualities typical of citrus fruits. The compound is commonly obtained through mechanical expression of the fruit's pulp. As a natural ingredient, grapefruit juice is referenced in authoritative chemical information repositories such as PubChem. It serves as a source material in both flavor and cosmetic industries due to its fresh, citrus sensory profile.

Occurrence, Applicability & Potential Uses

Grapefruit juice naturally occurs in the fruit of Citrus paradisi, a species cultivated extensively for fresh consumption and juice production. The juice carries the typical citrus sensory characteristics and is extensively employed in cosmetic formulations as a perfuming agent and for skin conditioning. It is also utilized in flavor applications to impart citrus notes. Standards such as FEMA (US) regulate its use within flavorings and personal care products to ensure quality and safety compliance.

Physico-Chemical Properties Summary

The physico-chemical profile of grapefruit juice is influenced by its aqueous nature and the presence of volatile compounds that confer the citrus odor and flavor. These properties make it suitable for incorporation into various formulations requiring fresh citrus notes. The juice's compatibility with cosmetic ingredients supports its use as a skin-conditioning product and perfuming additive. Additionally, the juice’s chemical constituents suggest stability under formulation conditions typical of cosmetic and flavor applications, although it is not recommended for fragrancing due to regulatory considerations.
