Optimization of fermentation conditions for producing Indian rock bee (Apis dorsata) mead using response surface methodology

Abstract

Mead is a traditional drink which results from the alcoholic fermentation of diluted honey carried out by yeast (Saccharomyces cerevisiae KF233529). The present investigation was carried out for the optimization of fermentation parameters for maximizing the yield of ethanol. Response Surface Methodology (RSM) based central composite design was employed to obtain best combination of temperature, fermentation time and total soluble solids (TSS). The optimum conditions for ethanol yield were temperature 28°C, TSS 15°Brix and 6 days after fermentation. The model showed that the value of R 2 (0.9998) was high and p-value of interaction of variance was <0.0001. Hence the model can be said to be of highly significant.

Utilization of Different Concentration Sugarcane Molasses to the Quality of Goat Feces-Chicken Excreta-Coconut Husk Organic Liquid Fertilizer

“…Composting on liquid materials does not cause an increase in temperature as in composting solid materials because the high water content causes the heat release reaction to being suppressed during the process of organic matter transformation (Srimeena et al, 2014), similar results were shown in previous studies (Fitriyanto et al, 2019). The temperature range during fermentation is classified as mesophilic fermentation (25 o C to 45 o C); most of the fermentation process of liquid organic matter takes place in that temperature range (Grubel et al, 2014).…”
