Description

Isohumulonealead CAS NO 128442-25-1 is a specialized chemical compound belonging to the class of hop-derived alpha acids, specifically an isomerized derivative. This product is critical for ensuring consistent bitterness, flavor stability, and foam quality in the brewing process. It is primarily required by industrial-scale breweries, beverage flavoring manufacturers, and research institutions focused on fermentation science and product development.

Application

• Primary Bittering Agent in Beer Production: Used to provide a clean, consistent bitterness in lagers, ales, and other malt beverages.
• Flavor Standardization: Essential for achieving precise and reproducible flavor profiles across large production batches.
• Foam Stability Enhancement: Contributes to the formation and retention of a stable, creamy head on finished beer.
• Research & Development: Serves as a high-purity reference standard for analytical method development and quality control laboratories.
• Pre-Isomerized Hop Product Formulation: A key ingredient in the manufacture of advanced, shelf-stable hop extracts and products.
• Non-Alcoholic and Craft Beverage Innovation: Applied in the development of novel bitter flavors for craft sodas and non-alcoholic beers.
