Microbiological Characteristics and Alcohol Content By Raman Spectroscopy.
The alcohol content varies in function of the fermentation time reaching percentages of 10.35 % (v/v) and 9.01 % (v/v) in the so called «run» stage. They are determined by gas chromatography and Raman spectroscopy. The end product has a high content of proteins (1 g/l), sugar reducers (4.75 g/l) and microbial populations in ranks of 45x108 UFC/mL for Saccharomyces sp., 41x107 UFC/mL for Zymomonas sp and 34x106 UFC/mL for Lactobacillus sp, that give the drink a high nutritional value. The microorganisms could be beneficial to the digestive system when ingested orally.
