2.4.3.3. Protein determination. The protein concentrations of the
extracts were measured by the Lowry, Rosebrough, Farr, and
Randall (1951) method, measuring absorbance at 660 nm, with
bovine albumin as a standard.
2.4.4. Ethanol concentration
The ethanol content in peach cubes was determined by using an
enzymatic method (Boehringer Mannheim GMBH, Germany).
Ethanol concentration is expressed as mg alcohol/100 g of sample
