Self-induced anaerobiosis fermentation in coffees inoculated with yeast: Effect on key enzymes of the germination process and its relationship with the decrease in seed germination.
Food Res Int
January 2025
Article Synopsis
- - The study aimed to track key enzymes and chemical changes in coffee during Self-Induced Anaerobiosis Fermentation (SIAF) with different yeasts, assessing their effects on seed germination.
- - Yeasts like Saccharomyces cerevisiae and Torulospora delbrueckii showed high enzyme activity and cell populations after fermentation, with significant changes in organic acids detected.
- - The findings indicate that fermentation methods affect seed quality differently, with conventional processing preserving more viable seeds compared to SIAF.
Allelopathic activity of coffee extracts: implications for germination and initial growth in select weeds and polyploidy in L.
J Toxicol Environ Health A
December 2024
Coffee beans contain compounds with allelopathic activity, such that some beans that do not meet quality standards might rather be used to obtain a natural herbicide which consequently might be employed to control undesired plants and avoid economic losses. Thus, the objectives of this study were: (1) to investigate the allelopathic effect of different concentrations of green (GC) and roasted (RC) coffee extracts on the inhibition of germination and initial growth of L. L.

Determining the maximum period that coffee can remain storaged is important aiming to reduce losses in quality and, consequently, allow the producer to achieve maximum profitability. The aim was to determine the suitable storage period for natural and fully washed coffees, under different conditions.
