Yield, humidity, acceptance and preference of tilapia submitted to smoking process

Abstract

On account of being considered a species of great importance for the global aquaculture the Oreochromis niloticus (Nile tilapia) was selected to execute this experiment. The aim was to evaluate yield, humidity, acceptance and preference for individuals of this species submitted to the hot and liquid smoking processes. The flattened fish yields were 38.46 and 54.44% for the hot and liquid smoking processes, respectively. The humidity verified during the treatment was 81.01% for individuals submitted to the liquid treatment and 69.30% for the hot-smoked ones. The sensorial analysis reveals that both treatments exhibited good acceptance, however the hot-smoked ones were preferred. Thus, the smoking process, whatever the form, traditional or liquid, is an alternative to aggregate value to the fish.
