Data are given as mean values ± SD (n = 3)
Values with different letters within the same column are significantly different at P < 0.05 by Duncan’s multiple range test
FDC freeze-dried concentrate, BDC boil-dried concentrate, SDC steam-dried concentrate, respectively
¹⁾ Yield is weight (g) of roe protein concentrate obtained from 100 g of raw YTR
²⁾ Protein yield (g) = yield x protein (%)
