Seven varieties of pelleted hops were extracted in ethanol with ultrasound and separated with SFC using carbon dioxide modified with ethanol as the mobile phase. The major terpenes and terpenoids, as well as the alpha and beta hop acids, were separated in a single run. The injection-to-injection run time was 13 min. At the current state of development, this method provides a rapid fingerprint of an extracted hop sample. Refinement of the extraction procedures and of the chromatographic parameters can be expected to yield more detailed analytical information on both the hop acids and the hop oils.","PeriodicalId":17225,"journal":{"name":"Journal of the American Society of Brewing Chemists","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46176538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, since they comprise many compounds with different physical properties and their concentration in beer is low, their simultaneous analysis has been a difficult task in the past, resulting in no method being proposed for inclusion in the Methods of Analysis of BCOJ. We propose a method for simultaneously analyzing the low-concentration compounds in beer using HS/SPME/GC/MS as one of the potential Methods of Analysis of BCOJ and evaluated its concurrent accuracy and inter-room repeatability and reproducibility. The collaborative work was conducted in 12 laboratories in Japan. The statistical summary of results is as follows: The relative standard deviation of repeatability (RSDr) ranged from 4.8 to 20.3% for β-myrcene, 3.7 to 5.2% for linalool, and 5.7 to 9.6% for geraniol; and the repeatability at 95% probability (r95) ranged from 1.5 to 15.3 µg/L for β-myrcene, 2.7 to 6.2 µg/L for linalool, and 0.7 to 2.1 µg/L for geraniol. The relative standard deviation of reproducibility (RSDR) ranged from 11.0 to 41.2% for β-myrcene, 8.1 to 11.6% for linalool, and 12.7 to 25.8% for geraniol; and the reproducibility at 95% probability (R95) ranged from 3.4 to 22.8 µg/L for β-myrcene, 5.6 to 15.6 µg/L for linalool, and 2.7 to 4.3 µg/L for geraniol. The obtained results were deemed acceptable. It was concluded that the method can determine hop aroma compounds in beer, low-malt beer, and third-category beer.","PeriodicalId":17225,"journal":{"name":"Journal of the American Society of Brewing Chemists","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2023-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43658925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
