Beverage spoilage yeast detection methods and control technologies: A review of Brettanomyces.

Beverage spoilage yeast detection methods and control technologies: A review of Brettanomyces. Int J Food Microbiol. 2018 Oct 20;283:65-76 Authors: Tubia I, Prasad K, Pérez-Lorenzo E, Abadín C, Zumárraga M, Oyanguren I, Barbero F, Paredes J, Arana S Abstract Spoilage yeasts detection is the key to improve the quality of alcoholic fermentation beverages such as wine and cider. The metabolic activity of the spoilage yeast causes irreparable damage to many liters of final products every year. Therefore, winemakers and cider-house companies suffer a substantial economic impact. Thus, over the years, many detection techniques have been proposed to control the occurrence of spoilage yeast. Out of the many spoilage yeast genera, Brettanomyces is one of the most commonly encountered in the beverage industry. Leveraging its ability to thrive in wine and cider conditions (low pH, high levels of ethanol, and low oxygenation levels), Brettanomyces can proliferate inside beverage production tanks. Moreover, their resultant by products reduce the quality of the beverage. While the beverage industry has made great strides in detecting harmful organisms, gaps remain. Traditional methods such as microscopy, cell plating, gas chromatography-mass spectrometry, etc. are often imprecise, expensive, and/or complicated. New emerging spoilage yeast detection platforms, such as biosensors and microfluidic devices, aim to alleviate these constraints. Novel...
