  1. All values are mean ± standard deviation of three replicates (n = 3)
  2. Values followed by the same letter in a row and the column do not differ significantly (p ≤ 0.05). The letters ‘a, b, c, d …’ denote differences within a row and ‘P, Q, R …’ within a column
  3. C: control; SDA: gravy treated with 0.25% sodium diacetate; PL: gravy treated with 2.5% potassium lactate; CL: gravy treated with 2.5% calcium lactate
