Enzymatic production of cassava flour using pectinase
This paper presents the studies of enzymatic activity of pectinase enzyme in liberation of starch from cassava (Manihot esculenta), especially in cassava flour. The starch granules in cassava is hold up by pectin molecules, in which its cell wall can be broken by pectinase enzyme activity. Hence, th...
