Canadian natto-type soybeans
Table 4 displays the quality data for 2020 Canadian natto-type soybeans. Mean 100-seed weight for 2020 natto-type soybean was 9.0 g, lower than in 2019 (9.8 g). Water absorption value was 1.21 g H2O per g seeds and water uptake factor was 2.21, similar to that for 2019.
The mean protein content for 2020 Canadian natto-type soybean was 39.0 g per 100 g dry matter, similar to that in 2019 (Table 4). The mean oil content was 20.7 g per 100 g dry matter, higher than the mean for 2019.
The mean sucrose content for 2020 Canadian natto-type soybean was 54.6 g per kg dry matter, lower than in 2019 (Table 4). The mean oligosaccharides content was 46.3 g per kg dry matter, higher than in 2019. The mean total isoflavones content was 3625 mg per kg dry matter, which was lower than the mean for 2019.
