Nonessential amino acids (g/100 g protein) of defatted oilseed protein isolates.

Amino acid	SPI	FPI	CPI
Alanine	3.23 ± 0.03^a	3.30 ± 0.08^a	2.66 ± 0.11^b
Arginine	7.43 ± 0.28^a	7.49 ± 0.18^a	3.91 ± 0.06^b
Aspartic acid	5.87 ± 0.29^a	5.86 ± 0.08^a	0.51 ± 0.02^b
Glutamic acid	12.52 ± 0.07^a	12.70 ± 0.76^a	9.70 ± 0.33^b
Glycine	3.05 ± 0.15^a	3.09 ± 0.12^a	2.82 ± 0.13^b
