Production and Evaluation of Quality Characteristics of Edible Fish Powder from Tilapia (Oreochromis mossambicus) and Silver Carp (Hypophthalmichthys molitrix)

Abstract

Fish is recognised as the most nutritious animal protein source, but because of its high deterioration nature, a huge number of fish are being wasted and susceptible to nutritional losses, resulting in a significant hurdle for expanding fish production. This research aimed to lessen these losses through the use of fish powder and to enhance the nutrients in people’s diets. In order to prepare fine fish powder, a dried fish paste was milled and sieved. Proximate analysis, mineral content, and physical and microbiological qualities were determined using standard analytical procedures. The protein content of Tilapia and Silver Carp fish powder was 63.63 g/100 g and 73.58 g/100 g, respectively. An appreciable amount of potassium, calcium, magnesium, phosphorus, iron, and zinc was also found in Tilapia and Silver Carp fish powder. The powder also holds an angle of repose of 29.4° and 26.7°, which assures a good flow property. Both Tilapia and Silver Carp fish powder have shown a near neutral pH value (6.40 and 6.32). The hedonic rating scale was used to assess the acceptability of fish powder-fortified cakes. The results showed that the cake fortified with Silver Carp fish powder outperforms the control and Tilapia fish powder sample in terms of taste, flavour, colour, texture, and overall acceptance, while the panellists also preferred the Tilapia fish powder sample. As a result of this research, a high-quality nutritious fish powder from Tilapia and Silver Carp can be prepared and adopted as a food fortifier.
