Consumers preference and perception of smoke-dried white shrimp (Nematopalaemon hastatus) in coastal areas of Ondo State, Nigeria

Abstract

The study assessed consumers' preference and perception of smoke-dried white shrimps in Igbokoda, a coastal area of Ondo State, Nigeria. The community was purposively chosen because the town is a major cluster for natives from coastal communities in Ilaje and Ese-Odo LGAs of Ondo State, Nigeria. Forty shrimp consumers (20 males and 20 females) were randomly selected for this study. They assessed the sensory properties of smoke-dried shrimps collected from processing units in Ayetoro and Bijimi. The two communities were purposively chosen for the predominance of white shrimp processing using smoking method. Five smoke-dried samples (A1-A5 and B1-B5) were collected from Ayetoro and Bijimi respectively. Panelists assessed the sensory attributes of white shrimps using a 9point hedonic scale. Results indicated that there were significant differences (p ≤ 0.05) in the organoleptic properties of the white shrimps. Samples A3, B2 and B3 had low acceptability while samples A1 and B5 were more accepted than the other samples. Taste of the samples was the highest significant factor that influenced general acceptability among assessors as indicated by the magnitude of its t-Stat. All the sensory attributes were positively correlated (R = 0.71) with general acceptability and 50% (R2 = 0.50) dependent on these sensory attributes. Majority of the respondents said they consumed white shrimps with no allergic reactions in dried form. Consumers were highly satisfied with smoked white shrimps in market places; however, off flavour, inadequate taste, odd appearance and the quantity of by-catches were the perceived reasons that determined consumers' satisfaction with shrimps in the market outlets. Hence, more emphasis should be laid on reducing off flavour, odd appearance, by-catches and increased utilization of white shrimp in food products. This would further increase consumers' satisfaction, patronage in market places, boost coastal economy and contribute to healthy living of consumers in Nigeria.

Bacteriological Assessment of Smoked-Dried White Shrimp (Nematopalaemon hastatus Aurivillius, 1898) Sold in Calabar, Nigeria

“…White shrimp (Nematopalaemon hastatus, Aurivillius, 1898) is one of the most important commercially valuable seafood consumed not only in Nigeria but also in sub-Saharan Africa and other regions of the world. Due to its nutritional benefits, they are consumed daily in soups and other recipe among coastal and inland dwellers [1].…”

“…Carbohydrate content in seafood is known to be very little and as such recommended for weight loss [5,3]. In Nigeria, white shrimps are often sold and consumed in dried form, however, most coastal dwellers consume it fresh [1].…”

Bioeconomic feasibility of aquaponics in South Africa: leapfrogging for sustainable development of freshwater aquaculture.

“…Several processing methods such as smoking, drying and freezing are used to increase the shelf life of catfish in Nigeria as a result of its high perishability. Smoking, the most feasible processing method and widely acceptable product form (Eyo, 1999), is very affordable, inhibits microbial spoilage and increases the organoleptic properties of the final product (Omobepade et al, 2018). Smoked catfish are commonly packed in…”
