Quality of Canadian food-type soybeans 2021
Canadian natto-type soybeans
Table 4 displays the quality data for 2021 Canadian natto-type soybeans. Mean 100-seed weight for 2021 natto-type soybean was 8.8 g, which is slightly lower than for 2020 (9.0 g). The water absorption value was 1.19 g of water per g of seeds and water uptake factor was 2.19, similar to that for 2020.
The mean protein content for 2021 Canadian natto-type soybean was 38.3 g per 100 g of dry matter, lower that for 2020 (Table 4). The mean oil content was 22.0 g per 100 g of dry matter, higher than the mean for 2020.
The mean sucrose content for 2021 Canadian natto-type soybean was 50.9 g per kg of dry matter, lower than in 2020 (Table 4). The mean oligosaccharides content was 44.3 g per kg of dry matter, which was similar to that for 2020. The mean total isoflavones content was 3419 mg per kg of dry matter, which was lower than the mean for 2020.
