A: juice diluted to 8 Bx and supplemented with molasses up to 12 Bx. B: juice diluted to 10 Bx and supplemented with molasses up to 12 Bx. Head fractions were collected
at temperatures ranging between 45 and 77 C, body fractions at 78–85 C and tail fractions at 89–95 C. Volume and ethanol concentration are mean values ± SD (n = 3). 1 Ethanol production was calculated as milliliter of ethanol produced per 100 mL of fermentation broth. 2 In ethanol production column, means with the same letter are not significantly different.
