Autohydrolysis was demonstrated to be an efficient technique
to recover polysaccharides with high antioxidant activity from SCG,
particularly when applied at 160 ◦C for 10 min, and using a liquid/solid
ratio of 15 ml water/g SCG. Under these conditions, it was
possible to obtain a lyophilized material containing 29.29%(w/w) of
polysaccharides,from which galactose was the most representative
sugar, followed by mannose, glucose, and arabinose. Additionally,
the lyophilized material contained a high content of phenolic compounds
(234.14 07 mg GAE/g LM) and reducing sugars (93.93 mg
GLU/g LM), and presented high antioxidant activity, which as con-
firmedby fourdifferentmethods. Furthermore,thepolysaccharides
presented thermostability in a large range of temperature, being
therefore of great interest for industrial applications, mainly in the
food industry, for encapsulation of additives or as prebiotics, for
example, due to their high antioxidant potential and other functional
properties.
