with the pH of the solution adjusted using 0.1 M HCl or 0.1 M NaOH, as required. Using spectrophotometry atλmax = 518 nm, the concentration of the AR73 dye was determined after a 0.5 mL sample of the solution was taken out at different times until equilibrium was established. All ...
19,20. In citrus, investigation of the vacuoles of the acid lime juice cell suggests citrate uptake can be accounted for by direct primary active transport mechanisms involving ATP21. In addition, the studies in acidic lemon and limes indicated that citric acid accumulation was accompanied by a ...
Materials for the manufacture of pectin on an industrial scale are fruits and, in addition to strained lees (mostly comprising endocarp) after preparing juice of citrus fruits such as lemon and lime, the strained lees after preparation of apple juice is used as well. Such strained lees mostly ...
