Abstract

The study on physical properties (surface granules, solubility and paste clarity) of three differences degree of substitution (DS) octenyl succinylated cassava starch (OSCS; DS value 0.005, 0.010 and 0.015) and native cassava starch (NCS) were carried out. The OSCS granules exhibited slightly rough surfaces and the sides of these granules were porous. More cavities on surface of OSCS were observed when degree of substitution increased. The highest solubility was found in OSCS with DS 0.015 at temperature of 85 ◦C.   Paste clarity of OSCS had significantly increased (p <0.05) with increasing of octenyl succinyl group and OSCS with DS value 0.015 had the highest paste clarity. Applications of OSCS in salad dressing by reducing of the egg yolk in the range of  30% – 80 % were tested. The result showed that using of OSCS at 0.1% by weight in 30% reduced egg yolk salad dressing had similar physical properties with control, and was accepted by the panelists. Key words: native cassava starch, octenyl succinylated cassava starch, reduced - fat salad dressing
