CHARACTERISATION OF SOYBEAN BREEDING LINES (Glycine Max (L.) Merrill FOR THE PRODUCTION OF SPROUTS Keli Cristina Cantelli March/2015 Advirsors: Dra. Juliana Steffens Dra. Clarice Steffens Dra. Mercedes C. Carrão-Panizzi Soybean (Glycine max (L.) Merrill) is a crop of commercial and nutritional importance. Its use as human food has been encouraged by the diversity of soy products and provide potential health benefits. However, their products still suffer restrictions by consumers because the distinctive taste and presence of anti-nutritional factors. An alternative, is the use of soybean as food, consume it as sprouts, which are healthy and nutritious. For production of soybean sprouts are necessary special cultivars that must have small seed size, as its main characteristic. This study aimed the production and characterization of soybean sprouts from cultivar BRS 216 (developed for this type of product) and the breeding lines A, B and C from the Embrapa ́s breeding program. The germination vigor of the seeds was determined in 100 seeds. The sprouts were produced in trays, in temperature of 25 °C in a controlled chamber, relative humidity of approximately 99%. Soybean grains and sprouts were characterized for moisture, proteins, lipids, ash, isoflavones, Kunitz trypsin inhibitor and phytic acid, the weight and length of sprouts, were also measured. Grains of Line A presented the highest germination vigor (95%), followed by BRS 216 (93%), line C (89%) and line B (87%). With the germination process, protein and the isoflavones content increased in average, 8.96% and 34.56%, respectively, and the antinutritional factors were reduced in 26,91% average activity of the Kunitz trypsin inhibitor and 13,78% in the phytic acid content. The cultivar BRS 216 presented the highest protein content in grains (41,96 g.100g) and in sprouts (47,70 g.100g). The line A showed higher content of trypsin inhibitor in grains (27,56 mg IT.g) and in sprouts (19,62 mg IT.g), however it showed lower content of phytic acid in sprouts (1,13 g.100g). This line also showed a higher concentration of total isoflavones in grains and in sprouts (340.10 and 406,38 mg.100 g, respectively). The lower content of total isoflavones was observed in line B (119,11 mg.100 g in the grains and 153,07 mg.100 g in the sprouts). The weight and length of the sprouts, after four days of germination, were higher for line A (8,03 cm and 214,36 g) and for cultivar BRS 216 (7,31 cm and 140,93 g), respectively. These results show that the lineage A, compared with BRS 216, developed by Embrapa has the potential to produce buds and as an alternative for consumers. |
