hop absolute

Hop absolute is a concentrated aromatic extract obtained from the flowers of Humulus lupulus, commonly known as hop. It presents as a dense, viscous substance with a strong herbal character noted for its deep green, spicy, and leafy qualities, closely associated with valerian notes. This absolute is used primarily for its distinctive herbal odor and flavor properties, making it valuable in both perfumery and food flavoring sectors. Known synonyms include humulus lupulus absolute and humulus lupulus flower extract. The material is derived through solvent extraction of hop flowers and is recognized in chemical databases such as PubChem. Its natural botanical origin and concentrated sensory characteristics make it a specialized ingredient in flavour and fragrance formulations.

Hop absolute is sourced naturally from the flowers of the hop plant, Humulus lupulus, which grows widely in temperate climates. This extract captures the complex herbal and spicy aroma of the hop plant and finds application chiefly as a flavor and fragrance agent. In flavoring, it is notably employed to enhance beer's characteristic taste, contributing to its distinctive herbal and bitter notes. As a fragrance ingredient, hop absolute imparts aldehydic, fern-like, forest, hyacinth, and tobacco nuances to complex aroma formulations. Usage recommendations and safety guidelines are outlined by IFRA (Global), which limits its inclusion to a maximum of 0.0800% in fragrance concentrates, ensuring compliance with global standards for safe use.

Hop absolute is characterized by its solubility properties, being soluble in alcohol but insoluble in water. This selective solubility impacts formulation strategies, facilitating incorporation into alcohol-based perfumes and flavor solutions while limiting aqueous applications. Its dense, viscous consistency and herbal aromatic profile arise from a complex mixture of volatile compounds extracted from hop flowers. The chemical nature of hop absolute contributes to its stability and performance in fragrance and flavor compositions, where its herbal, spicy, and green notes are desired. The absence of significant hazards based on available safety data supports its controlled use within recommended concentration limits.
