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