In this study, retting was carried out by Aspergillus niger. The pH, galacturonic acid (GA), and total reducing sugar were determined; the end point was identified by the classic empirical processes and by the maximal GA content of the retting water. The process gave clear and resistent fibers, and the retting time was similar to that of current industrial processes with bacterial enzymes. Control of total acidity was not required, since the pH remained close to neutrality throughout the entire process.
RESUMO
The empirical test was compared with the determination of pH, total acidity, and galacturonic acid (GA) as methods for establishing the termination time of the retting process in flax. The GA dosage was the best method for determining the end point of this process by distinctly dividing the phases of retting and over-retting in the bacterial loosening of flax fiber. This end point is critical in the production of standard fibers for the weaving industry.
