Physicochemical properties, antioxidant activities and microbial communities of Ethiopian honey wine, Tej

Development of mixed starter culture for the fermentation of Ethiopian honey wine, Tej

“…yeast and lactic acid flora of Tej by using phenotypic characterization method 4 . Similarly, Lactobacillus and Saccharomyces were the dominant taxa for the Tej samples collected from different part of the country 7 . However, the dominance level was substantially different within and across the samples collected from different households.…”

“…Due to the absence of direct inoculation, the fermentative microorganisms responsible for converting honey-water mixture to ethanol during Tej fermentation are thought to be found in raw materials and utensils 2 . This spontaneous honey fermentation could be the primary cause of inconsistency in the quality of Tej produced by different households 7,8 . The honey quality difference might also contribute to this variation in the physicochemical properties of the final product 6 .Traditional Tej producers prefer crude honey instead of purified honey for the making a good quality Tej 5 .…”

“…Furthermore, as the fermentation period drew close to an end, the microbial dynamics moved to this microbial dominance 9 . Moreover, Tej exhibited good antioxidant activity, possibly inherited from honey and "gesho" (R. prinoides) 7 . The antioxidant capacity of Tej was also increased as the fermentation progressed to completion 9 .…”

“…Previous reports on the physicochemical and microbial ecology of Tej did not provide enough information to modernize this spontaneous fermentation system 4,[6][7][8] . The selection of starter culture strains and process variable optimizations are still open gaps to be filled for the complete transformation of this process.…”

Microbiome dataset of spontaneously fermented Ethiopian honey wine, Tej

“…In nutshell, this amplicon sequencing dataset provides a useful collection of data for modernizing this spontaneous fermentation into a directed inoculated fermentation. Detail discussion on microbiome of Tej samples is given in [1] .…”
