Abstract:
The focus of this study was to develop the best formulation of concentrated stock from
blood cockle (Anadara Granosa) formulation that will be accept by panels. This study
also involved the determine of physicochemical and proximate characteristics of the end
product. Anadara granosa species were used due to cheap source of protein compared to
other aquatic food and it is abundantly available in Malaysia. Results for analysis were
evaluated in value of mean and standard deviation with significant different of p<0.05.
Five formulation were produced differentiate by the amount of cockle stock extract used,
which are formulation A (10%), formulation B (30%), formulation C (50%), formulation
D (70%) and formulation E (90%). Fresh blood cockle was purchased at local market.
Shucking method was used by using steaming process. Physicochemical analyses were
conducted for pH, viscosity, colour and water activity. Proximate analysis were
conducted include crude protein, crude fat, ash and moisture where significant different
(p<0.05) were reported in all the attributes. Attributes in sensory evaluation were smell,
gravy colour, salty taste, foreign taste, taste and overall acceptance. In Physicochemical
analysis, formulation B recorded highest pH (5.42a), Formulation E have highest viscosity
(58.4a) and formulation A has highest water activity (0.989a). While in proximate
analysis, formulation E with the highest amount of cockle stock extract (90%) was
recorded high in crude protein (30.09%), crude fat (0.63%) and ash (1.73%), but it has the
lowest content of moisture (88.38%). In sensory evaluation, only attributes colour,
foreign taste and overall acceptance has significant different (p<0.05) recorded. Among
five formulations, majority of 40 panels has accepted formulation A with the lowest
amount of cockle stock extract ( 10%) as their preference better than others with mean
score 4.93. Thus, it can be concluded that the cockle concentrated not only well accepted,
but minimized in raw ingredient used. The product is economically safe and high in
protein.
