A total of 62 volatile compounds were identified, including aldehydes, esters, alcohols, ketones, pyrazines, and furans, among which aldehydes were the most abundant compounds. Based on the principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) models, infant nutritional powder (YYB) from different manufacturers could be clearly distinguished. Among them, 2-hydroxybenzaldehyde, 1, 2-dimethoxyethane, 2-isobutyl-3-methoxypyrazine, and methyl butyrate were the four most critical differential volatiles. In addition, these differences were also manifested in changes in fatty acids. The reason for this phenomenon can be attributed to the difference in the proportion of raw materials used in nutrition powder, micronutrient content, and the packaging process. In conclusion, this study provides comprehensive information on the flavor quality of YYB, which can be used as a basis for quality control of YYB.<\/jats:p>","DOI":"10.3390\/foods13050648","type":"journal-article","created":{"date-parts":[[2024,2,21]],"date-time":"2024-02-21T05:42:46Z","timestamp":1708494166000},"page":"648","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Comparative Analysis of Characteristic Volatile Compounds in Five Types of Infant Nutrition Powders by HS-GC-IMS and GC-MS"],"prefix":"10.3390","volume":"13","author":[{"given":"Zhihua","family":"Yang","sequence":"first","affiliation":[{"name":"Shenzhen Institute of Standards and Technology, Shenzhen 518033, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinjin","family":"Li","sequence":"additional","affiliation":[{"name":"Shenzhen Key Laboratory of Food Nutrition and Health, College of Chemistry and Environmental Engineering, Institute for Innovative Development of Food Industry, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoming","family":"Guo","sequence":"additional","affiliation":[{"name":"Shenzhen Key Laboratory of Food Nutrition and Health, College of Chemistry and Environmental Engineering, Institute for Innovative Development of Food Industry, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e4161","DOI":"10.1097\/MD.0000000000004161","article-title":"Effect of Prenatal and Postnatal Malnutrition on Intellectual Functioning in Early School-Aged Children in Rural Western China","volume":"95","author":"Li","year":"2016","journal-title":"Medicine"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"ckab165.152","DOI":"10.1093\/eurpub\/ckab165.152","article-title":"A Study of Commercially Available Complementary Foods for Infants and Young Children under 36 Months","volume":"31","author":"Santos","year":"2021","journal-title":"Eur.
