There were no significant differences in contents of iron, zinc and cadmium between the two strains, and was 4.0%, 7.8% and 7.3% higher than BPY, respectively. Contents of total amino acids, required amino acids and required amino acids for baby development in BPY were significantly higher than that in IRY. Contents of protein and soluble sugar in BPY were higher than that in IRY, but crude fiber content in BPY was lower than that in IRY. ［Conclusion］ The nutritional value of BPY was higher than that of IRY.
