Summary: A sustainable valorization platform for organic waste has yet to be fully developed. This study focuses on a new valorization route that converts food/agricultural waste to biodiesel using yellow mealworm larvae. The non-catalytic conversion process shows high tolerance against water and impurities, making it a promising method for biodiesel production.

Summary: This study compared the chemical composition and antioxidant potential of essential oils from the Lippia genus through chemometric analysis. The results showed that the essential oils exhibited significant antioxidant activity, with different compounds in Lippia alba being effective in various antioxidant methods. The findings highlight the importance of Lippia compounds for protecting against oxidative stress and their potential use in food preservation.

Summary: This study aimed to optimize the parameters for polydimethylsiloxane (PDMS) analysis and detection by looking at resolution and number of scans. Experimental parameters were refined through a full factorial experimental design (FFD) and extended to a face centered central composite design (FCCD) for optimization. Repeatability of the results was investigated using principal component analysis (PCA) and hierarchical cluster analysis (HCA) to select the most relevant analytical parameters.

Summary: This study aims to identify discriminating chemical constituents in banana odors from the Philippines and Ecuador using GC-MS characterization. Ester is recognized as a major chemical class in selected banana odors, and compounds like 2-hexenal, ethyl acetate, and hexanoic acid, ethyl ester have been identified. Principal component analysis and hierarchical cluster analysis successfully differentiated the banana odors, achieving 100% discrimination of selected banana odors.

Summary: This study investigated the use of Raman spectroscopy as a promising analytical tool in medical diagnostics and a method to distinguish between healthy individuals and those with cholangiocarcinoma. The results showed that there were differences in the Raman spectra of amino acids, proteins, and lipid vibrations between healthy individuals and cancer patients. Specific ranges in the Raman spectra were identified as effective in distinguishing between the two groups.

Summary: This study aimed to identify patterns in water quality data of pit lakes through principal component analysis and hierarchical cluster analysis, revealing differences among different types of pit lakes. While surface water parameters could separate elements into clusters based on chemical groups in most cases, the clustering of pit lake data did not clearly differentiate between types. Principal component analysis showed that three components for both water and sediment data explained a significant portion of the variance.

Summary: The study tested the biological activities of primary and secondary metabolites of 69 green cabbage varieties, showing significant differences in amino acid and polyphenol content among varieties. Glutamate and rutin were found to be the most abundant, with high genetic diversity. PCA analysis grouped cabbage varieties based on amino acid and polyphenol content, providing a theoretical basis for improving cabbage nutritional quality.
