The effects of polyunsaturated phospholipids on changes in the thermal and physical properties of starch systems during mixing, baking and storage were studied. In the presence of phospholipids (PLs) or polyunsaturated fatty acidcontaining PLs (PUFA-PLs), the viscoelastic properties of starch dough, such as stress, modulus of elasticity and viscosity coefficient were decreased, and the gelatinization enthalpy (⌬h g ) of dough also decreased slightly, but the starchlipid complexes (⌬h s-l ) of dough and bread increased distinctly. Twenty-one days after its storage, the retrogradation rate (k) that was estimated by the change of re-gelatinization enthalpy (⌬h t ) of starch containing PLs or PUFA-PLs, was slowed by a factor of 1.98 or 3.28 for dough; and 1.60 or 2.07 for bread, respectively, when compared with that of the control. The changes in retrogradation value of starch in bread seemed to correlate with the retrogradation value of starch in dough in differential scanning calorimetric data (r 2 =0.93). These changes in thermal and physical properties of dough and bread appeared to be caused by the formation of complexes between starch and the PLs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
