Chicken bone extract was hydrolyzed using Protamex™ and Flavourzyme™ to obtain chicken bone enzymatic hydrolysate (CBEE), which was subjected to the Maillard reaction to produce Maillard reaction chicken flavoring (MRCF). The volatile compounds in CBEE and MRCF were comprehensively analyzed using solvent-assisted flavor evaporation (SAFE) and solid-phase microextraction (SPME) combined with two-dimensional gas chromatography–olfactometry–mass spectrometry (GC×GC-O-MS). A total of 40 odor active compounds were identified and their odor activity values (OAV) were calculated. Among them, 11 compounds contributed significantly to the overall aroma (OAV ≥ 1). Key contributors, including 2-methyl-3-furanethiol, furaneol, 5-(2-hydroxyethyl)-4-methylthiazole, and maltol, were confirmed through aroma recombination and omission experiments. The results highlight that the Maillard reaction significantly enhances the richness and complexity of the meaty and roasted aromas, driven primarily by the increased levels of sulfur-containing and heterocyclic compounds.

However, the high nutrient content and moisture levels in fresh rose hips make them highly susceptible to microbial spoilage, which significantly reduces their shelf life and increases food waste. Despite the importance of understanding the microbial communities responsible for spoilage, limited research has focused on this aspect of rose hip preservation. This study aims to bridge this gap by investigating the microbial communities involved in the spoilage of four varieties of Rosa rugosa from Pingyin, Shandong Province, using high-throughput sequencing, MALDI-TOF-MS, and gas chromatography-mass spectrometry (GC-MS) for microbial and volatile organic compound analysis. High-throughput sequencing of 16S rRNA and ITS genes identified a diverse microbial community consisting of both bacteria and fungi, including spoilage-associated species such as Bacillus, Pantoea, Rahnella, Alternaria, and Aspergillus. MALDI-TOF-MS further confirmed these findings, revealing a broader range of microbial species. GC-MS analysis of volatile organic compounds (VOCs) identified key spoilage-related compounds, such as alcohols, ketones, and esters, with correlations between specific VOCs and microbial populations. This study provides valuable insights into the microbial dynamics of rose hip spoilage and offers potential markers for spoilage detection. The integration of high-throughput sequencing, MALDI-TOF-MS, and GC-MS sets a new benchmark for food preservation research, enhancing our ability to monitor and control microbial contamination in fresh fruits.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"142 ","pages":"Article 107471"},"PeriodicalIF":4.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
