The Role of Microorganisms in Cocoa Production and Optimization

Cocoa is a tree from the Malvaceae family, with a height ranging between ۴ and ۱۰ meters. Like other plant foods, the cocoa plant contains antioxidants and substances that reduce the risk of diseases such as heart disease. Pure and unrefined cocoa has a bitter taste that requires processing for consumption. The quality of cocoa depends on several parameters, including cocoa types, environmental growth conditions, cultivation techniques, and post-harvest treatment methods applied to cocoa beans. The purpose of this research is to explore the role of microorganisms in the production and optimization of cocoa. The first stage of chocolate production involves a seven-day microbial fermentation of cocoa beans. A wide range of microorganisms, including yeasts, lactic acid bacteria, and acetic acid bacteria, are involved in this process, where the temperature rises up to ۵۰ degrees Celsius. Microbial products such as ethanol, lactic acid, and acetic acid are produced, forming the precursors to chocolate flavor. Excessive fermentation can lead to the dominance of bacilli and filamentous fungi, which can negatively alter the taste of chocolate. Today, the effects of different microorganisms on the quality and taste of produced chocolate are clear. Therefore, by selecting appropriate microorganisms for fermentation, the taste and quality of desired chocolate can be controlled and predicted.
