First limiting amino acid was sulfur-containing amino acid. Mean value of protein score in June and November was 75.5 in School A, and 74 in School B.3) E/T ratio was 2.46 in School A, and 2.42 in School B. Mean value of E/T ratio in both months was 2.45 in School A, and 2.42 in School B.4) Egg score was 68 in School A and 66 in School B. First limiting amino acid in both cities was sulfur-containing amino acid. These tendencies were the same to results obtained in June.5) Human's milk score was 84 in School A and first limiting amino acid was tryptophan or lysine.
