Variations in cell wall monosaccharide composition during seed development in Coffea arabica L. Comparison between Coffea arabica var. Bourbon and Coffea arabica var. Laurina

open access: yesTrees, 2015
Cell wall polysaccharide composition changed over seed development. Differences between B and BP only concerned the fruit growth period. Coffea arabica var. Laurina, also known as ‘Bourbon Pointu’ (BP), is a natural mutant of Coffea arabica var. Bourbon (B).

Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, Volume 16, Issue 5, Page 906-920, May 2026.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

Genetic Diversity ofCoffea arabica

open access: yes, 2021
Coffea arabica L. is a native coffee species probably originated in Abyssinia, now Ethiopia. The genetic diversity of C. arabica has economic implications directly related to profits by breeding for developing new varieties to a global market. The economic value of C. arabica genetic resources are estimated at US$ 420 million, considered a 10% discount

Exploring portable NIR spectroscopy in transmittance and reflectance modes for the authentication of Brazilian coffees with geographical indications

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4038-4048, May 2026.
Abstract BACKGROUND Geographical indications (GIs) certify the link between coffee origin and quality, enabling premium pricing and protecting producers. However, the high market value of GI coffees increases their vulnerability to fraud, underscoring the need for reliable and practical authentication methods.
