- Abstract:
- ... Coffee is considered an important source of organic nutrients and minerals, and these resources are strongly affected by agricultural management. Among the minerals, the element Mg is important, which is essential for both plants and humans. In this work, the effects of agricultural management on the absorption and storage of Mg by commercial, ground, roasted Arabica coffee were investigated. For ...

Response surface methodology was utilised to maximise the efficiency of GCO extraction. Structural changes occurring in the coffee residue were explored using scanning electron microscopy, and extraction kinetics was establis ...

- Abstract:
- ... Coffee is the second most traded commodity worldwide after oil both in terms of volume and value. The study was therefore initiated to evaluate the quality of highland coffee varieties grown in the region. For this purpose, coffee bean samples of the varieties Merdacheriko, Yachi, Wush Wush, Buno wash, 741, 7440, Ababuna, and Ageze were collected from trees which were grown in Adet and Woramit Agr ...

- Abstract:

We analyzed the concentrations of 44 trace elements in 53 samples of roasted Arabica coffee beans (Coffea arabica) from 21 different countries. Variations in absolute elemental concentrations of coffee beans arise through varying degrees of roasting (from green through dar ...

With this, new technologies and several harvester models have emerged. These harvesters have regulations that can influence the efficiency of harvesting, the selectivity of fruits and the preservation of the crop. In this way, the understanding of the behavior of ...

Estimating coffee yield by measuring components of yield rather than complete harvests can improve the ability to account for heterogeneous conditions common in shade-grown farms and other agroforestry systems. We developed a rapid estimation technique that predicts yield per plant from (1) a visual estimation of the number of fruits per lateral summed across all laterals per plant, and (2) an ave ...

Coffee, like many other crops, is sensitive to climate change and recent studies have suggested that future changes in climate will have a negative impact on its yield and quality. An urgent development and application of strategies against negative impacts of climate change on coffee production is important. Agroforestry-based system ...

The acknowledged marker of Robusta coffee, 16-O-methylcafestol (16-OMC), can be quantified by NMR as a mixture with 16-O-methylkahweol (16-OMK), which accounts for approximately 10% of the mixture. In the present study, we detected and quantified 16-O-methylated diterpenes (16-OMD) in 248 samples of green Coffea arabica beans by NMR. We did not observe any differences between genotypes introgresse ...

- Abstract:
- ... For decades coffees were associated with the genus Coffea. In 2011, the closely related genus Psilanthus was subsumed into Coffea. However, results obtained in 2017—based on 28,800 nuclear SNPs—indicated that there is not substantial phylogenetic support for this incorporation. In addition, a recent study of 16 plastid full-genome sequences highlighted an incongruous placement of Coffea canephora ...

- Abstract:
- ... Coffee (Coffea arabica) flowers synchronously and flowers are only open for a few days before senescing. Flower petals often decompose easily, containing higher concentrations of nutrients relative to other plant tissues. Thus, a pulse of petals into the detrital pool could be beneficial for the decomposer community and accelerate decomposition processes. Our research assessed the magnitude of the ...
