Abstract

This study aims to evaluate the influence of various processing variables, such as coffee type, roast level, and grind size, on fat content and water activity parameters in different types of coffee from the Ecuadorian Amazon. The research focused on analyzing how these variables affect the stability and quality of coffee during storage, which is crucial for preserving its organoleptic properties and shelf life. Coffee samples from different species and varying roast levels and grind sizes were analyzed using specialized equipment for water activity measurement and conventional methods for fat content determination. The results showed that both roast level and grind size significantly impact these parameters. In particular, it was observed that coffees with higher fat content, such as those from the Arabica species, require greater attention during storage to prevent oxidation, while finer grind sizes tend to increase water activity, potentially compromising the product's microbiological stability. These findings are relevant to the coffee industry as they provide valuable information for optimizing processing and storage conditions, ensuring better quality and longer-lasting products.
