Descriptive sensory characteristics were measured for porridges made from flour samples collected from the 1996 Kansas feed grain sorghum performance tests and from commercial food grain sorghum samples. Totals of eight and 11 sensory attributes characterized the feed grain and food grain samples, respectively. Two screenings provided descriptive sensory data for univariate and multivariate analyses. Four feed grain samples from the performance tests and seven food grain samples were identified as low in astringency and bitterness; six of these were used in 100% sorghum flour muffins to determine consumer acceptability. Flavor acceptability of muffins was perceived as equal, and appearance was an important factor for acceptance. Optimization of all sensory attributes for each specific product is needed to increase acceptability of grain sorghum in consumer products.
