Chocolate flavors vary depending on the origin of the cocoa beans used. Differences in soil, microorganisms, and environmental factors contribute to the formation of flavor precursors in cocoa beans. During cocoa bean fermentation, environmental temperature has been shown to alter metabolite concentrations. However, the correlation between the metabolite profile of cocoa beans and the temperature of their region of origin has not been fully defined. In this study, the metabolite profiles of Indonesian cocoa beans of various origins were evaluated using gas chromatography/mass spectrometry-based analysis, and were found to differ depending on the origin of the bean. Subsequently, the correlation between metabolite profile and environmental temperature of the origin was assessed using orthogonal projection to latent structure regression (OPLS-R) analysis. The analysis revealed that seven metabolites were associated with temperature: γ-aminobutyric acid (GABA), ethanolamine, glycerol, isocitric acid + citric acid, succinic acid, malic acid, and saccharic acid. The findings of this study will be valuable to chocolate industries for the production of single-origin chocolates.

Broad beans, a seasonal leguminous vegetable renowned for their distinctive flavor and high-quality plant protein, present unique opportunities for culinary and nutritional applications. To better understand the impact of various blanching processes on their characteristics, we employed headspace gas chromatography-ion mobility mass spectrometry (HS-GC-IMS) and biochemical tests to evaluate changes in color, volatile compound content, and levels of antioxidant-related substances following different blanching treatments. Our findings revealed that microwave blanching significantly influenced the a* metric and antioxidant capacity of broad beans.

In this work, the functional activities including α-glucosidase, α-amylase, angiotensin converting enzyme (ACE) inhibitory activity, and antioxidant activity of mixed grains (mung beans, cowpeas, and quinoa) fermented with Bacillus amyloliquefaciens SY07 were investigated. The volatile flavor of the mixed grains collected every 12 h during 72 h-fermentation were further detected as well. The inhibition on α-glucosidase and α-amylase reached up to 89.

This paper presents a comprehensive dataset of mid-infrared spectra for dried and roasted cocoa beans ( L.), along with their corresponding theobromine and caffeine content. Infrared data were acquired using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy, while High-Performance Liquid Chromatography (HPLC) was employed to accurately quantify theobromine and caffeine in the dried cocoa beans.

Cadmium (Cd) concentrations in cacao beans from Latin America often exceed limits for trading. A better understanding of the mechanisms of Cd accumulation in Theobroma cacao L. trees is necessary to advance mitigation strategies.

The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012. The conclusions were reached on the basis of the evaluation of the representative uses of phosphine as a post-harvest indoor insecticide to control insects infesting stored grains (barley, oat, rye, wheat), cacao and coffee beans, tree nuts and oilseeds and dried fruit via gassing application (gas-tight rooms/container).
