Resumen
Pectin is a collection of polysaccharides, which play an important
role in controlling the pore size of the plant cell wall,
regulating cell-cell adhesion, and providing a source of signalling
molecules that elicit a range of cellular responses. Apart
from this, pectins are of interest because they are an attractive
hydrocolloid for various food applications. The kind and distribution
of decorative groups in the pectic molecules largely
determines for which application a particular pectin is most
suitable. After the extraction of starch from potato tubers, a
by-product is obtained, which is relatively rich in pectin. However,
the quality of these pectins is poor compared to that from
other sources such as citrus and apple. Rather than trying to
change the structural cha.racteristics of potato pectin post-harvest,
we have embarked on achieving this in the potato plant
itself. This paper summarises the structural features of pectin, the distribution of various peetic
epitopes in tuber cell walls, the enzymes involved in its biosynthesis and degradation, and
strategies employed to alter its fine structure in planta.
