Abstract
Tubers, especially potato and sweet potato besides offering numerous desirable nutritional
and health benefits remain underexploited. In the current study, potato and sweet potato were
processed into different forms (flour and mash) to access their potential for development of
specialty pasta. Potato and sweet potato flour (20 to 40%) and mash (8 to 24%) were mixed
with wheat semolina for formulation of pasta blends. Resultant pasta was evaluated for its
nutritional and biochemical composition, pasting profile, functional properties, cooking
quality and in-vitro starch digestibility. Significant (p<0.05) increase in the nutritional
composition, bioactive constituents and antioxidant activity in pasta from potato and sweet
potato (flour and mash) was observed. Pasting profiles of specialty pasta showed variable
patterns. Resultant potato and sweet potato (flour) pasta at varying proportions portrayed an
increase in the water absorption capacity, water solubility index and gruel solid loss. Sweet
potato mash pasta depicted lower starch digestibility. Specialty (potato and sweet potato)
pasta with 30% flour and 16% mash were selected as best compositions on the basis of their
sensory attributes. Significant influence over the colour characteristics (L*, a*, b*, hue and
chroma values) of potato and sweet potato pasta was examined. The selected samples of
specialty pasta were packed in polypropylene and their storage studies were conducted at
ambient conditions for 5 months. Specialty pasta remained acceptable in terms of quality
(cooking, moisture content, free fatty acid content and overall acceptability) with progression
of storage period. This can be a newer way for development of non-conventional pasta with
health benefits.
