Trash fish has several weaknesses, such as having tight spines,
having little meat, and being highly perishable. The purpose of this study
was to determine the functional characteristics of trash fish through fillet
preparation techniques and types of fish. This study used a completely
randomized design method. The first factor is the type of fish consisting of
Orangefin ponyfish (Leiognathus bindus Valenciennes, 1835), Chacunda
gizzard-shad (Anodontostoma chacunda Hamilton, 1822) and Sardine
(Sardinella Fimbriata Valenciennes, 1847). The second factor was the type
of preparation technique which consisted of mechanical, blanching, 1 % acid
immersion and 1 % papain enzyme immersion. The data obtained were then
analyzed descriptively from the preparation technique for each observation
parameter and presented in tabular form and plotted in graphical form. The
results of this study indicate that Orangefin ponyfish, Chacunda gizzardshad and Sardine fish have a range of functional properties of the three types
of fish, namely: foaming power (17.68 % to 61.87 %), foam stability (50 %
to 57.14 %), emulsifying power (3.31 % to 4.29 %), emulsion stability
(1.91 % to 3.37 %), WHC (33.9 % to 46.64 %), and OHC (24.75 %
to 29.57 %).
