In Brazil, however, the consumption of soybean and soybean products such as tofu is limited mainly due to its astringent flavor. Soybean quality for food processing includes gel strength of tofu, soybean flavor and color. The aim of this assignment was to investigate the effects of cultivars and curdling agent on gelling properties for tofu production. In this study one breeding line (BRM94-52273) and thirteen cultivars (BRS 155, BRS 156, BRS 183, BRS 184, BRS 185, BRS 212, BRS 213, BRS 214, BRS 215, BRS 216, BRS230, BRS231 and BRS 233) developed by the breeding program of Embrapa Soybean, and three curdling agents: gluconolactone, magnesium chloride anhydrous (MgCl2) and calcium sulfate dihydrate (CaSO4.2H2O) were evaluated for tofu production. Gel strength of tofu (firmness) was measured in a Shimadzu Texture Analyzer - EZ Test Series. Tofu samples, which presented higher firmness, were submitted to sensory analysis. This analysis was accomplished with 80 non-trained panelists. Cultivar BRS 155 showed highest firmness (1.719 N) when treated with gluconolactone. Cultivar BRS 212 treated with MgCl2 showed firmness of 1.010 N and firmness value of 0.584 N. when it was treated with CaSO4. For sensory analysis the chosen samples were those which obtained high values of firmness with each one of the curdling agents (BRS 155/gluconolactone, BRS 212/CaSO4 and BRS 212/MgCl2). Results of tofu curd sensory analysis indicated that BRS 212 treated with MgCl2 had the highest acceptance, around 77,5%.1 aALIGLERI, T.
