ABSTRACT
This study was attempted to investigate the sensory and textural characteristics of mungbean starch gels with soy bean oil and sucrose fatty acid ester(SE) addition during room temperature storage. Freshly prepared mungbean starch gels, with and without soy bean oil and SE, were stored at 25℃ for 24, 48 and 72 hours. The color value, syneresis, texture and sensory properties of the gels were measured. The lightness(L) of the gels with soy bean oil and without additives was similar whereas that with SE was lower than that without additives. Syneresis of the gels with soy bean oil and SE was lower than that without additives. Rupture stress, rupture strain and rupture energy of the freshly prepared gel with 2∼4% soy bean oil were increased, but there were no differences in rupture properties between the gel with soy bean oil and that without additives. Rupture stress, rupture stain and rupture energy of all the gels with SE were decreased. Addition of soy bean oil to the gel did not change the texture profile of the gel, whereas hardness, springiness and chewiness of the gel with SE were decreased. In sensory evaluation, the acceptability of freshly prepared gel with soy bean oil was similar to that without additives, whereas that of the gel with 2% soy bean oil stored for 24 hours was higher than that without additives. The acceptability of the gel with SE was decreased significantly.
