Abstract
ABSTRACTKnowledge of relationships between kernel composition and sensory attributes of sweet corn could be helpful in selection of corn genotypes for the food industry. Frozen samples of four shrunken2 sweet corn inbred lines and two commercial hybrids were assayed for dimethyl sulfide (DMS), phytoglycogen and sugar concentrations. Sensory evaluation of the same samples by a trained descriptive panel was conducted to determine intensity of attributes of the three main components of sweet corn quality (aroma, flavor and texture). The relationships between sensory attributes, overall liking and kernel characteristics were determined. Sweetness was strongly correlated with sweet corn flavor, total sugars and sucrose. Grassy flavor and aroma were logarithmically correlated with DMS. Volatiles present in the inbred lines, but not in the commercial samples, could also contribute to the grassy flavor. Sweetness, starchy flavor, crispness and tenderness were the key sensory attributes correlated with overall liking. Selection for tender genotypes with high sugar concentration would increase the eating quality of the product.
