Grapes from rootstock 420A produced lower pH must than 110R, however other maturity indices like soluble solids content and titratable acidity were not different between the two rootstocks (LEE; STEENWERTH, 2013).
Increment in dehydration temperature resulted in substantial decrease of total titratable acidity (TTA), approximately 15.
7 mg 100 g-1) contents were obtained from the control treatment, the highest titratable acidity (0.
The dry matter (DM), pH, titratable acidity (TA) and fat were determined according to the standard Association of Official Analytical Chemists (AOAC) methods [19], at seven days intervals for a 21 days' storage period under refrigeration conditions (4 - 6[degrees]C).
Thus, with increase in NAA concentrations the titratable acidity was decreased which may be due to early ripening of fruits caused by treatment, where acid might have been used during respiration or rapidly converted into sugars.
Then, fruits were taken to the Postharvest Laboratory of the Physiology Department at Federal Rural University of Semi-Arid (UFERSA), where the following physical and chemical characteristics were evaluated using 10 fruits in three maturity stages: weight, length, diameter, soluble solids, pH, titratable acidity, firmness and vitamin C.
Part of fresh silage after opening the silos was separated for analysis of pH, titratable acidity (TA) and buffering capacity (PT) by the method described by Silva and Queiroz (2002).
In total, 12 extracts were prepared, 6 from raw coffee powder and 6 from roasted coffee powder, for evaluation of pH, total solids and titratable acidity.
The titratable acidity (TA) was determined by titration of the filtrate (dilution 1:5) with NaOH 0.
