Influence of short chain fructo-oligosaccharide (SC-FOS) on the dough rheological, microstructural properties and, bread quality during storage.

Objective of this study was to understand the impact of short chain fructo-oligosachharides (SC-FOS) on the
dough rheological characteristics and bread quality. SC-FOS was used in place of sucrose and studied for dough
rheology, bread making and sensory characteristics. Farinograph, extensograph, amylograph and rheometer
were used to evaluate the rheological characteristics. The interaction of SC-FOS with starch was explored from a
structural perspective, as well as how SC-FOS influences to keep the bread softer over a period of time. For
mechanistic insight, FT-IR (Fourier transform infrared spectroscopy), PXRD (Powder X-ray diffraction), and SEM
(Scanning electron microscope) were used to investigate the structural changes. Starch crystallization through
molecular and supramolecular reorganization primarily dictates the texture of bakery products, particularly the
firmness of product like bread where moisture content is higher; SC-FOS can successfully slow down the crystallization
of starch and yield softer product during a shelf life of 7 d. Bread with SC-FOS has shown better
retention of water and modulating mobility of water. As a result, incorporating SC-FOS to bread has led to a
positive outcome, with improved quality and an excellent sugar replacer.
