Summary: Cocoa beans, which are used to produce chocolate and related products, are greatly influenced by microbial activity during post-harvest handling, especially fermentation, drying, and storage. This review explores the factors affecting each stage, the process mechanisms, and the latest technologies for improving cocoa bean quality. Fermentation plays a crucial role in determining cocoa bean quality as it involves various microorganisms that produce flavor compounds. Drying and storage processes are also important to maintain quality and prevent microbial contaminants. Various technologies, including the use of microbial starters during fermentation and vacuum drying and controlled atmosphere during storage, can enhance cocoa bean quality. However, controlling microbial activity remains a challenge, necessitating continuous development of post-harvest technology.

Summary: Our study demonstrated that fermentation by Pediococcus pentosaceus degrades allergenic proteins in Tartary buckwheat, leading to a reduction in IgE-binding activity. Comparison with unfermented Tartary buckwheat peptides showed that 756 fragments associated with allergenic proteins were upregulated and the expression of 213 fragments was reduced by 71.83% after fermentation. Bioactivity prediction identified six peptide fragments derived from Fagt 1, potentially contributing to the residual allergenicity in the fermented product.

Summary: The comparative chemical composition of different parts of Faustrime fruits was analyzed using GC-MS and UHPLC-HRMS QTof. The data obtained were combined to define the fruit's complex antioxidant activity. The principal component analysis showed the occurrence of specific compounds in different parts of the fruit, such as alpha-bisabolol and alpha-trans-bergamotol in the pulp and albedo, hexanoic acid in the seeds, and various coumarins and phenolics in the peels. The higher radical scavenging activity of the pulp was attributed to the presence of citric acid.

Summary: This study elucidated the transfer pathways of Cd from soil to cacao nibs in a high Cd accumulating cacao cultivar. The results showed that the transfer from branches to nibs was more direct than from leaves to nibs. It also suggested that the main contribution of Cd in nibs came from the phloem tissues of the branches rather than leaf remobilization.

Summary: Classifying food samples based on their countries of origin is essential in the food industry, utilizing LC-MS for detailed chemical analysis. Challenges such as experimental conditions and instrumental effects make this task difficult, with PCA offering limited separation and LDA being influenced by non-linear compound dependencies. Introducing a compound selection criterion based on Gaussian distribution of intensities can enhance origin clustering in the dataset.

Summary: This study focused on mathematical modeling of cocoa bean fermentation, revealing the importance of fermentation mechanisms and parameters for quality control. The results supported biochemical mechanisms such as consumption of fructose by lactic acid bacteria and production of acetic acid by yeast, while showing the sensitivity of model parameters to factors like cocoa bean variety, temperature control, and container material. The findings suggest that mathematical modeling could serve as an alternative to traditional chemical fingerprinting for interpreting fermentation data.

Summary: We report the discovery of the first two cationic palladium(II)-oxo clusters (POCs) containing f-metal ions, and investigate their physicochemical characterization. The molecular structure of these novel POCs consists of an octahedral {Pd6O12} core capped by eight M-IV ions, forming a cationic, cubic assembly {Pd6O12M8IV}. We also found that these POCs can form host-guest inclusion complexes with 4-sulfocalix[n]arenes, and can be used as pre-catalysts for electrocatalytic CO2 reduction and HCOOH oxidation.
