Abstract
The focus of this investigation was to utilize the
protein present in tuna waste by enzyme hydrolysis
and characterization of protein hydrolysate (TPH).
Yellowfin tuna waste was used to prepare the
hydrolysate using 0.5% (w/w) bromelain enzyme. It
was characterized for nutritional, functional and
antioxidant properties. The protein content in the
derived protein hydrolysate was 95.3 ± 3.1%. The
foaming capacity as well as foam stability was
maximum at pH 6.0 and the property decreased
when pH deviated from neutral. Emulsifying
properties viz., emulsifying activity index as well as
emulsion stability index was least at 4.0 pH. DPPH
radical scavenging activity of TPH revealed an IC50
value of 4.06 mg ml-1.
