Abstract :Soybean (Glycine max L.) is a versatile crop characterized by its cholesterol- and saturated fat-free composition and high-quality protein content. Evaluating parameters such as antioxidant capacity, moisture, and ash content is crucial for assessing the nutritional quality of soybeans, which are widely consumed both globally and in Türkiye. Antioxidants are compounds that mitigate or neutralize the harmful effects of free radicals in the body. Dietary natural antioxidants are among the most critical factors for enhancing the body\\\'s antioxidant defense system. This study aimed to evaluate the antioxidant capacity, moisture, and ash content of early-maturing soybean genotypes cultivated under the Sivas ecological conditions. The highest antioxidant activity using the ABTS method was observed in the ÜNV-2 genotype (11.82 μmol TE/g dw), while the DPPH method revealed the ÜNV-15 genotype as the highest (4.03 μmol TE/g dw). The moisture content of the soybean genotypes and varieties used in this study ranged from 8.75% to 12.34%, while the ash content varied between 2.86% and 4.05%. Differences in all investigated traits among the samples were statistically significant at the 1% level. As a result, the ÜNV-2 and ÜNV-15 genotypes were prioritized due to their relatively higher antioxidant activity, and the Ataem-7 variety was preferred for its lower moisture content.
