Traditionally, the McGill #2 mill has been used for lab milling to assess rice milling performance as per the recommendation of the Federal Grain Inspection Service (FGIS). However, as the FGIS is phasing out the use of the McGill #2 mill, there is a need to recalibrate milling assessments for standardized milling evaluation across various labs. Thus, the objective of this study was to assess the milling performance of three laboratory mills (McGill #2, Satake, and Zaccaria mills) on the head rice yield (HRY), milled rice yield (MRY), and whiteness index (WI) of rice.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Findings</h3>\u0000 \u0000 <p>MRY was greater than 60%, while HRY varied between 28% and 60% over all treatments. The Satake mill demonstrated a higher MRY and is significantly different from the McGill #2 and Zaccaria mills. Similarly, the Satake mill produced the highest HRY, followed by the Zaccaria mill and the McGill #2. On the contrary, the Satake mill exhibited the lowest WI, about 0.6 and 0.9 percentage points (pp) lower than McGill #2 and the Zaccaria mill, respectively.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Rice cultivars and mill types had the most significant impact on the aforementioned explored variables. Among the mills, the Satake mill displayed the highest MRY and HRY but had the lowest WI. We recommend that the 0.4 SLC value associated with well-milled rice be reviewed, which could perhaps lead to more HRY and impact the economic value of rice for growers.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Significance and Novelty</h3>\u0000 \u0000 <p>This study offers insights into the milling capabilities of the evaluated mills. However, further research is necessary to understand and optimize other modern laboratory mills.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9807,"journal":{"name":"Cereal Chemistry","volume":"102 1","pages":"199-210"},"PeriodicalIF":2.2,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cche.10856","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143110647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
