Summary: This study aimed to identify compounds in minor Zingiberaceae spices grown in Indonesia that are linked with antioxidant and alpha-glucosidase inhibitor activities. The results showed that Zingiber aromaticum Val., Alpinia malaccensis (Burm.f.) Roscoe, Amomum compactum Sol. ex Maton, and Zingiber purpureum Roscoe exhibited the highest antioxidant and alpha-glucosidase inhibitor activities. Furthermore, the total phenolic content positively influenced the antioxidant activities.

Summary: This study identified the volatile compounds in Jinhua ham samples using different extraction methods and analysis techniques. The results showed that needle trap (NT) extraction method extracted the highest number of volatile compounds, while solid-phase microextraction (SPME) headspace adsorption had the highest extraction efficiency. Principal component analysis effectively distinguished the changes in aroma due to aging time in the Jinhua hams. Butyrolactone, 2,6-dimethylpyrazine, 2,3,5-trimethylpyrazine, phenylacetaldehyde, and acetic acid were identified as the main volatile compounds in the three-year aged Jinhua ham samples. This study provides a theoretical basis for the selection of extraction methods for volatile aroma compounds in Jinhua ham.

Summary: This study analyzed the volatile organic compounds of different lemon varieties during fruit ripening and found that the proportions of different volatiles changed at different stages. Monoterpenes decreased while sesquiterpenes, alcohols, aldehydes, and esters increased during fruit ripening. Disease-resistant varieties had a higher proportion of oxygenated volatiles. These findings provide important theoretical support for the utilization of lemon fruits and the innovation of disease-resistant germplasm resources.

Summary: Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HSSPME-GC-MS) was used to analyze volatile compounds in minced pork meat during storage, with the origin of aromatic hydrocarbons in pork being verified by a migration test. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were utilized to characterize the profile of volatile compounds and identify potential volatile markers associated with pork spoilage. Three compounds were identified as additional indicators for quality control of pork based on their importance in discrimination of pork with different storage times.

Summary: A novel headspace solid-phase microextraction method combined with gas chromatography-mass spectrometry was developed to extract volatiles from fresh Amomum tsaoko (FAT) from four districts. Fifty compounds were identified in FATs from four regions, and 32 volatiles determined by orthogonal partial least squares-discriminant analysis contributed to the differentiation of FATs from the four distinct regions. This study not only developed a feasible method to extract volatiles from FAT but also established a theoretical basis for differentiating FATs from different regions.

Summary: In this study, a high-efficiency enrichment method using solid-phase micro extraction (SPME) arrow configuration was developed for determining trace-level volatile terpenes in fish tissue. The method demonstrated good linearity and repeatability, with the thicker coating providing higher sensitivity and expanding the range of detected compounds for headspace SPME. Theoretical calculations validated the benefits of increased coating thickness in enhancing method sensitivity.
