The present work aimed to evaluate the biochemical, physicochemical and melissopalynological characteristics of two honey types obtained from the same production period (a light one and a dark one) and to apply them in the fermentative process of mead by three yeasts (Saccharomyces cerevisiae Montrachet, Saccharomyces bayanus Premier Blanc and Saccharomyces cerevisiae Safbrew T-58), incubated at 30 °C and 150 rpm for 24 h. The fermentations were carried out in 500 mL Erlenmeyer flasks containing honey must (30 oBrix), supplemented with yeast extract (5 g.L−1), malt extract (5 g.L−1), peptone (10 g.L−1), magnesium chloride (0.05 g.L−1), ammonium sulfate (0.3 g. L−1) and ammonium phosphate (0.05 g.L−1), inoculated with an initial culture of 106 cells. mL−1 and incubated at 30 °C for 264 h. A difference in the honey’s melissopalynological profile was observed, as well as a consequent difference in the physicochemical characteristics. Higher cell growth was observed: S. cerevisiae Montrachet (9.5 x 107 cells.mL−1, 72 h), S. bayanus Premier Blanc (9.2 x 107 cells.mL−1, 72 h) and S. cerevisiae Safbrew T-58 (6.1 x 107 cells.mL−1, 96 h), as well as a higher substrate consumption (80.7, 86.3 and 73.8%) and higher ethanol production (14.0, 15.0 and 12.7%), respectively, in the fermentation of the must with dark honey.

巴西两种多花蜂蜜类型的生化、物理化学和花粉分析及其对蜂蜜酒生产的影响

目前的工作旨在评估从同一生产时期获得的两种蜂蜜类型(浅色蜂蜜和深色蜂蜜)的生化、物理化学和蜂花粉学特征,并将它们应用于三种酵母(Saccharomyces cerevisiae Montrachet,Saccharomyces bayanus Premier Blanc 和Saccharomyces cerevisiae Safbrew T-58),在 30 °C 和 150 rpm 下孵育 24 小时。发酵在 500 mL 锥形瓶中进行,该烧瓶含有蜂蜜葡萄汁(30 o Brix),并补充有酵母提取物(5 gL -1)、麦芽提取物(5 gL -1)、蛋白胨(10 gL -1)、氯化镁( 0.05 克-1)、硫酸铵(0.3g.L -1 )和磷酸铵(0.05gL -1 ),用10 6 个细胞的初始培养物接种。mL -1并在 30°C 下孵育 264 小时。观察到蜂蜜的蜂花粉特征的差异,以及随之而来的物理化学特征的差异。观察到更高的细胞生长:S. cerevisiae Montrachet (9.5 x 10 7 cells.mL -1 , 72 h)、S. bayanus Premier Blanc (9.2 x 10 7 cells.mL -1 , 72 h)和S. cerevisiae Safbrew T -58 (6.1 x 10 7 个细胞.mL -1, 96 h),以及在用黑蜂蜜发酵葡萄汁时,底物消耗量更高(80.7%、86.3% 和 73.8%)和乙醇产量更高(14.0%、15.0% 和 12.7%)。
