Aspartame Degradation in Solution As Impacted by Buffer Type and Concentration

Storage stability of tagatose in buffer solutions of various compositions

“…These results are similar to those reported by Bell and Wetzel (1995) and Pachapurkar and Bell (2005) for other reactions. Bell and Wetzel (1995) showed that the rates of aspartame degradation increased as buffer concentration and pH increased.…”

“…Bell and Wetzel (1995) showed that the rates of aspartame degradation increased as buffer concentration and pH increased. Aspartame also degraded faster in phosphate buffer than citrate buffer.…”

Combined Effects of a Buffer and Solvent on Tetramethylpyrazine Formation in a 3-Hydroxy-2-butanone/Ammonium Hydroxide System

“…7) Mori and Manning 9 ) have performed a large-scale synthesis of a Schiff base from AlaMHis and glyceraldehyde in a potassium phosphate buffer at pH 7, and the significant bifunctional catalytical effect of phosphate on the Schiff base formation in diketopiperazine from aspartame has recently been reported by Bell and Weetze1. 10 ) Methanol was used as a reaction medium for the Schiff base formation between amines and glucose by Rosen et al…”

Increase of electrical properties using a novel mixed buffer system in an enzyme fuel cell

“…Ionic strength at constant pH can affect the electrical mobility of a protein by the changes in ion atmosphere and the charge of the protein, which might occur due to specific interaction with the ions of buffer [23]. In addition, phosphate buffer salts which are small with proton donating and accepting groups in close proximity can simultaneously donate and accept protons [24]. MP-11 activity seemed to be improved by MOPS, because it reported that both the stabilization and activation of MP-11 effects were observed when MOPS buffer used [25].…”

“…The current density of the electrodes depends on the concentration of the phosphate elution buffer, while the activity of the electrodes does not [31]. In addition, phosphate buffer ions have the same ability as high functional catalysts through their ability to donate or accept protons for the constant ionic strength [24]. Fig.…”
