چکیده انگلیسی
The aim of the present study was to evaluate the off-flavour masking potential of pea dextrin (PD) in emulsions rich in Ï-3 and Ï-6-fatty acids in comparison with maltodextrin (MD) and 2-hydroxypropyl-β-cyclodextrin (HPBCD). After optimisation of the homogenisation procedure, stable emulsions were prepared and stored for up to eight weeks. The development of six secondary lipid oxidation products: propanal, 1-penten-3-one, 1-penten-3-ol, hexanal, (E,E)-2,4-heptadienal and (E,Z)-2,6-nonadienal, was monitored via headspace gas chromatography after solid-phase microextraction. Sensory evaluation of the emulsions was performed by a trained panel. PD already showed masking properties for propanal, 1-penten-3-one, hexanal and (E,E)-2,4-heptadienal during validation of the gas chromatographic analysis, but not for 1-penten-3-ol or (E,Z)-2,6-nonadienal. During storage, the course of lipid oxidation was similar in all emulsions as concluded from the hydroperoxide value. Results from the sensory evaluation confirmed a masking of rancid off-flavour. In conclusion, pea dextrin is suitable for masking off-flavour resulting from early stages of lipid oxidation.
