Some Physico-Chemical Properties of Lactose: IV. The Influence of Salts and Acids Upon the Mutarotation Velocity of Lactose

摘要: Summary The mutarotation of lactose is accelerated by molecules, and ions other than those hydrogen hydroxyl. This phenomenon attributed to general acid base catalysis. catalytic influence the anions weak acids much greater that cations bases. effect lactate ion relatively small at concentrations below one-tenth normal, but it increases very rapidly as concentration becomes greater. effects salts found in dairy products have not yet been determined, seems probable their would be important, except possibly such concentrated milk powder ice cream. An empirical equation, based upon data Troy Sharp, has derived for estimating velocity solutions 25° C., various values pH.
