dc.description.abstractMultivariate image analysis applied to quantitative structureeproperty relationships (MIA-QSPR) was used to model the sweetness values relative to sucrose, log (RS), of a series of 40 disaccharides. Two dimensional molecular shape and atomic sizes were capable of predicting the changes in log (RS), giving results of calibration (R 2 1⁄4 0.97) and validation (R 2CV 1⁄4 0.86 and R 2test 1⁄4 0.94) very satisfactory. A novel polyhalogenated derivative with high estimated sweetness was proposed and a glucophoric pattern based on the well-known AH-B- g system has been discussed. The technique avoids unnecessary time and cost-demanding procedures, since new compounds (e.g. food additives) can be designed and their property estimated prior to compound preparation.pt_BR
