3.2. Ethanol yield
The alcohol yield of the F. communis flower stalks was estimated
through five trials. The highest alcohol yield was
67 cm3 kg1 based on dry flower stalks (0.020 m3 m3 juice) and
the lowest yield 44 cm3 kg1 (0.013 m3 m3 juice). The average
alcohol yield was 55.8 cm3 kg1 dry flower stalks (0.017 m3 m3
juice). The standard deviation of the ethanol yield was
12.5 cm3 kg1 dry flower stalks (0.004 m3 m3 juice).
