methods are preferred in food products. Enzymatic methods represent an innovative and clean alternative
for the “green” extraction of pectins reducing water pollution and waste generation. These methods are
based on the degradation of pectins by selective depolymerisation or their isolation by breaking the
plants cell wall [20]. Only few works have reported the use of these methods by comparing the enzymatic
extraction of pectins obtained from gold kiwifruit wastes at different stages of maturity with other
extraction methods [50,51]. In both cases, the enzymatic treatment was conducted at 25 °C for 30 min
with a Celluclast 1.5 L (1.05 mL·kg−1) at pH 3.70 ± 0.05. These methods showed relative low yields
(2.14% for peel, skin and seeds and 4.5% for pomace) when compared to acid/water extraction methods.
Nevertheless, the advantages of enzymatic methods, i.e., low temperatures that contribute to avoid
degradation of pectins and low cost, make this method a promising alternative that deserves further study.
