Fermentation Process Control with CDR CoffeeLab®
Fermentation is a fundamental process for removing mucilage from the bean. During this phase, the coffee undergoes transformations that contribute to the final quality of the product.
By analytically monitoring fermentation during the transformation process of the fruit into dried green coffee, CDR CoffeeLab® makes it possible to verify, differentiate and increase the quality of parchment coffee using objective parameters.
What you can analyse
With CDR CoffeeLab®, you can analyse both the pulp of the fruit and the fermentation liquid to monitor and control the different coffee production processes.
The fermentation process takes place thanks to endogenous microorganisms naturally present in coffee with the aim of removing mucilage.
In this phase, the sugars in the pulp and mucilage are transformed into organic acids and alcohol, characterising the organoleptic profile of the bean.
The different species of microorganisms present, the characteristics of the pulp and environmental factors such as temperature and oxygen influence the microbial activities that occur during fermentation.
The fermentation process therefore has an important impact on the final quality in the cup. The determination of objective parameters is crucial for controlling the transformation process that leads from cherry to green coffee.
Trend of parameters during fermentation
Total acidity and acetc acid increase up tp 36h and then decrease. Lactic acid is initially formed through malolactic fermentation which consumes the malic acid
The fermentable sugars consumed by the microorganisms decrease significantly over time by continuing to increase acidity and then produce alcohol. That alcoholic fermetationtakes place between 24 and 36 hours.
The above data refer to experimentations carried out on washed Honduran coffees during fermentations in November 2022 at CIC-JAP IHCAFE, Research and Training Centre in La Fé, Santa Barbara, Honduras.
