Pectinase in pears
Acta botanica neerlandica , Volume 3 - Issue 1 p. 108- 113
Finely minced tissue of Doyenne Boussoch pears was either extracted with dilute acid or treated with alkali prior to extraction to obtain pulp residues or extracts in which the ratio of pectinase inhibitor to pectinase has been changed in favour of the enzyme. The presence of pectinase in either the pulp residue or the extract was then demonstrated by reductometric and viscosimetric methods.
