Amount of TCA soluble peptides present in the three meat
systems was estimated according to the method of Ketnawa and
Rawdkuen(2011). Meat samples were homogenised with TCA
(5%), chilled for 1 h and then centrifuged (2500g for 15min).
Soluble peptides present in the centrifugate calculated as
micromoles of tyrosine/g of sample were estimated by Lowry method.
