“…Supercritical fluid extraction (SFE) with carbon dioxide is also used to collect the extract for beer brewing. [25][26][27][28] Another modern method is pressurized fluid extraction (PFE), which is employed for extracting different polyphenols. [29][30][31][32][33] PFE has been developed to extract bitter acids.…”

The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of Humulus Lupulus (Hops) Extract (reported functions include antimicrobial agent and hair conditioning agent) and Humulus Lupulus (Hops) Oil (reported function is fragrance). The Panel reviewed the relevant data related to these ingredients. Because final product formulations may contain multiple botanicals, each containing the same constituents of concern, formulators are advised to be aware of these constituents and to avoid reaching levels that may be hazardous to consumers. For these ingredients, the Panel was concerned about the presence of 8-prenylnaringenin, β-myrcene, and quercetin in cosmetics, which could result in estrogenic effects, dermal irritation, and genotoxicity, respectively. Industry should use current good manufacturing practices to limit impurities and constituents of concern. The Panel concluded that Humulus Lupulus (Hops) Extract and Humulus Lupulus (Hops) Oil are safe in cosmetics in the present practices of use and concentration when formulated to be non-sensitizing.

“…Among the state-of-the-art extraction methods used for extracting bitter compounds from hops, the most widespread is supercritical fluid extraction with carbon dioxide [8][9][10][11]14 . Another modern method, pressurized fluid extraction (PFE), has so far been employed for extracting different representatives of polyphenols 7,[15][16][17] .…”

The EBC method 7.7, currently used for determination of bitter acids in hop products, is a time‐consuming and laborious extraction technique. In this paper, our aim was to propose a new extraction method based on Pressurized Solvent Extraction (PSE) sometimes also called Pressurized Fluid Extraction (PFE) or Accelerated Solvent Extraction (ASE). Compared to conventional extractions, PSE offers a number of important benefits. PSE on OnePSE® automated extractor was used for extraction of α‐ and β‐acids from hops and hop products and the parameters influencing extraction efficiency and the influence of the sample preparation method were studied. The quantitative determination of α‐ and β‐acids in the extracts was accomplished by using an HPLC apparatus equipped with diode array detector. The experimental results were compared with those obtained by the standard EBC 7.7 method and the two methods were found to be fully compatible

LIQUID CO₂AND ETHANOL EXTRACTION OF HOPS PART III- EFFECT OF HOP DETERIORATION ON UTILISATION AND BEER QUALITY

Abstract: The quality of beers bittered with liquid CO2 and ethanoi extracts derived from fresh and deteriorated hops and the percentage utilization of alpha-acids therefrom were comparable. The importance of using analytical methods which measure bitterness substances per se is emphasized.
