Hops Flower Extract

Hops Flower Extract is a botanical extract derived from the dried female flowers (cones) of Humulus lupulus using a controlled extraction and concentration process to retain naturally occurring plant compounds like flavonoids, prenylated flavonoids, and bitter acids. It can be offered in various standard specifications and can be extracted from water or hydroalcoholic solutions to offer flexibility for the manufacturers in product development as per the formulation objective and market requirements. The extract is known for its characteristic botanical profile, formulation compatibility, and batch-to-batch uniformity and is a good raw material for manufacturers of dietary supplements, functional foods, beverages, and personal care products that are looking for plant-derived raw materials. For industrial applications, a standardized production, identity verification, purity testing, and quality management system are usually included in the workflow of professional suppliers, providing reliable composition, traceability, and manufacturing consistency. Its properties of stable processing and versatility in product formats enable customers to create differentiated products, while meeting the wide range of formulation, regulatory, and market needs, all with ease.

Humulus Lupulus Flower Extract contains a complex spectrum of naturally occurring phytochemicals, the most interesting of which is the prenylated flavonoids, especially the well-known xanthohumol, which is considered to be the major marker compound for standardized hop flower extracts in the botanical ingredient industry. The extract also contains naturally occurring related prenylflavonoids such as isoxanthohumol and 8-prenylnaringenin in differing concentrations depending on the extraction method and quality of the raw material. It also lends unique hop bitters to the extract, such as alpha acids (humulones) and beta acids (lupulones), as well as naturally occurring polyphenols, flavonoids, tannins, and aromatic volatile compounds that give the extract its unique botanical profile. The relative proportion of these constituents may change depending on the cultivar, harvest conditions, extraction technology, and standardization specifications. It is typically standardized at a specific concentration of xanthohumol or total flavonoids for commercial applications to ensure that the product is uniform and reproducible in its performance from batch to batch and in various formulations, including dietary supplements, functional food, beverage, and cosmetic products.

1. Raw Material Selection

Dried hop flowers (Humulus lupulus) are harvested at the proper stage of development and quality checked to confirm botanical identity, purity, moisture content, and general quality for consistent production for industry.

2. Cleaning and Grinding

The raw material is cleaned to get rid of impurities and milled to make the material uniform, which will enhance extraction efficiency and process uniformity.

3. Ethanol-Water Extraction

The controlled temperature, time, and ethanol-water ratio extraction of the ground hop flowers yields a consistent botanical extract without the use of food-grade solvents. The ground hop flowers are extracted with a food-grade ethanol-water solution in a controlled manner under specific temperature, time, and solvent ratio to yield a consistent botanical extract without the use of food-grade solvents.

4. Filtration and Concentration

The plant material is filtered to eliminate the plant mass and concentrated under vacuum to allow a reduction of the amount of solvent and an increase in concentration of the main plant constituents.

5. Standardization

The concentrated extract is standardized to meet the target specifications (xanthohumol or total amount of flavonoids), assuring the uniformity of the product from one batch to another for commercial use.

6. Spray Drying

The liquid extract is standardised and spray-dried to a stable free-flowing powder, optionally with a food-grade carrier.

7. Quality Control

Every batch is subjected to various tests for specification compliance such as active substance content, moisture, microbiological quality, heavy metals, residual solvents, and other routine tests.

8. Packaging and Storage

The final Hops Extract product is repacked in sealed, light- and moisture-resistant containers and stored in a cool and dry area to ensure product quality during storage and transit.

Humulus Lupulus Hops Extract is generally added to a finished product used for adult consumers in food, beverage, and supplement applications that are naturally derived or plant-based formulations. These end products are typically targeted at those who are looking for botanical blends, plant-forward products, or clean-label alternatives, such as people who adopt a general health and wellness lifestyle or those with a preference for plant-based or clean-label products. It is also frequently used in formulations aimed at the consumer market, including nutritional supplements, functional beverages, and nutraceuticals, to add to product differentiation and complexity through the use of botanical extracts. Moreover, its cosmetic and personal care suitability makes it a popular ingredient in topical formulations that appeal to those who seek to use naturally derived ingredient formulations and botanical skin care formulations. It has a wide applicability in the commercial product development realm and can be used across a variety of common consumer demographics, depending upon the product positioning, regulatory concerns, and market approach.
