From commercially available apple pectin, pectic acid was isolated by
alkaline catalysed hydrolysis and physico-chemically characterised. Th
e densities and viscosities of aqueous solutions of pectic acid and it
s lithium salt were determined at concentrations up to 0.016 g cm(-3).
The effect of the addition of simple salt and the degree of neutralis
ation on the apparent specific volume and on the limiting viscosity nu
mber of dilute aqueous solutions of pectic acid and its lithium salt w
as investigated. (C) 1998 Published by Elsevier Science Ltd. All right
