The purpose of the study was the attempt of the isolation of the thermophilic fungi from raw coffee beans. The material constituted of 24 coffee beans samples came from 12 countries. The isolation and the identification of the thermophilic fungi was conducted according to Biłaj [2], Biłaj and Zacharczenko [3]. The study proved, that raw coffee beans were the rich source of the thermophilic mycoflora. From all tested samples 270 species were isolated. The most refused sample came from Ecuador--81% coffee beans were infected. The most of species (90% from among isolated) were species belonged to the Thermomyces lanuginosus.

The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State Spain and co-rapporteur Member State Germany for the pesticide active substance phosphine are reported. 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).

Chlorogenic acids (CGAs) play a key role in defining the quality and functionality of coffee products. CGA fingerprints of black instant coffee (BIC) and coffee bean extract (CBE) were profiled using ultra-performance liquid chromatography-mass spectrometry and analyzed by chemometrics. A total of 25 CGAs were identified.

Unlabelled: (Arabica) and (Robusta) are valuable agricultural products traded worldwide. In this study, we designed specific primer pairs for Arabica and Robusta using chloroplast genes to distinguish and quantify the two types of coffee beans. We assessed the specificity, sensitivity, and applicability of the qRT-PCR assay using all the primer pairs.

Article Synopsis
- This study measured acrylamide levels in traditionally brewed Ethiopian coffee varieties from regions including Jimma and Sidama.
- Acrylamide concentrations varied among coffee types, with the highest levels found in Hararge and Nekemte, while brewed coffee showed significantly lower concentrations for both first and second brews.
- Daily acrylamide intake from coffee was well within safe limits, though some concerns were noted for Nekemte coffee in specific areas, suggesting a need for strategies to reduce acrylamide levels to protect health.
