This study aimed to optimize drying conditions to enhance the umami composition and sensory properties of honeybee brood umami powder (HBb-UP). A factorial design was employed to evaluate the effects of drying temperature and time on umami-related amino acids, 5\u2032-nucleotides, and equivalent umami concentration (EUC). Drying temperature and time significantly influenced the formation of umami compounds, with the optimized drying condition (65 \u00b0C for 3 h) promoting higher umami composition and improved sensory attributes of HBb-UP. Volatile flavor analysis using GC\u2013MS and an electronic nose revealed a diverse range of aroma compounds contributing to the overall flavor profile. Descriptive sensory evaluation and electronic tongue analysis indicated that umami and saltiness were the dominant taste attributes, accompanied by mild seasoning and fishy notes associated with interactions between amino acids and nucleotides. Principal component analysis demonstrated positive correlations among umami-related amino acids, nucleotides, EUC, and sensory attributes, confirming their combined contribution to taste perception. These findings highlight the potential of optimized HBb-UP as a natural flavor enhancer and functional ingredient for use in sustainable food systems.<\/jats:p>","DOI":"10.3390\/foods15122234","type":"journal-article","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T08:19:52Z","timestamp":1782202792000},"page":"2234","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Characterization of Umami Compounds and Volatile Profiles of Honeybee Brood Umami Powder Under Optimized Drying Conditions: Implications for Sensory Properties"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9817-306X","authenticated-orcid":false,"given":"Supakit","family":"Chaipoot","sequence":"first","affiliation":[{"name":"Multidisciplinary Research Institute, Chiang Mai University, Chiang Mai 50200, Thailand"},{"name":"Center of Excellence in Microbial Diversity and Sustainable Utilization, Chiang Mai University, Chiang Mai 50200, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0831-7457","authenticated-orcid":false,"given":"Sirinthip","family":"Jaijoi","sequence":"additional","affiliation":[{"name":"Multidisciplinary Research Institute, Chiang Mai University, Chiang Mai 50200, Thailand"},{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2956-3581","authenticated-orcid":false,"given":"Gochakorn","family":"Kanthakat","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6874-8726","authenticated-orcid":false,"given":"Kuntathee","family":"Chaimueng","sequence":"additional","affiliation":[{"name":"Multidisciplinary Research Institute, Chiang Mai University, Chiang Mai 50200, Thailand"},{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0347-4979","authenticated-orcid":false,"given":"Chalermkwan","family":"Somjai","sequence":"additional","affiliation":[{"name":"Processing and Product Development Factory, The Royal Project Foundation, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7052-0779","authenticated-orcid":false,"given":"Pairote","family":"Wiriyacharee","sequence":"additional","affiliation":[{"name":"Processing and Product Development Factory, The Royal Project Foundation, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9917-390X","authenticated-orcid":false,"given":"Rajnibhas Sukeaw","family":"Samakradhamrongthai","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9426-0043","authenticated-orcid":false,"given":"Pattavara","family":"Pathomrungsiyounggul","sequence":"additional","affiliation":[{"name":"Faculty of Agro-Industry, Chiang Mai University, Chiang Mai 50100, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Worachai","family":"Wongwatcharayothin","sequence":"additional","affiliation":[{"name":"Faculty of Humanities, Chiang Mai University, Chiang Mai 50200, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1038-176X","authenticated-orcid":false,"given":"Rewat","family":"Phongphisutthinant","sequence":"additional","affiliation":[{"name":"Multidisciplinary Research Institute, Chiang Mai University, Chiang Mai 50200, Thailand"},{"name":"Center of Excellence in Microbial Diversity and Sustainable Utilization, Chiang Mai University, Chiang Mai 50200, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lange, K.W., and Nakamura, Y.
