Research Project: Postharvest Processing to Add Value to Catfish

Location: Food Processing and Sensory Quality Research

Project Number: 6054-43440-045-00
Project Type: Appropriated

Start Date: Dec 07, 2012
End Date: Jun 30, 2014

Objective:
Objective 1: Characterization of off-flavors and color in catfish. This research would evaluate the incidence and diversity of off-flavors and color of hybrid and channel catfish throughout the year across several locales, in order to devise strategies to improve the quality of products entering the market place. In addition, improved methods for sampling catfish ponds would be developed for determining the incidence of off-flavors. Objective 2: Enhance the utilization of byproducts from aquaculture product processing. This research will aim to determine the composition of the catfish processing co-product stream and its seasonal variation, as well as identify and develop +opportunities for value added products from this co-product stream.

Approach:
This project will work closely with the commercial processing industry to improve the perception of catfish quality, and devise new uses for catfish by-products. Research will evaluate the incidence and diversity of off-flavors and color of both hybrid and channel catfish fillets and other primary products throughout the year across several regions, in order to devise strategies to improve the quality of products entering the market place. In addition, improved methods for sampling catfish ponds would be developed for determining the incidence and type of off-flavors and colors present. Approaches will include characterizing off-flavors in catfish products using both sensory evaluations and analytical chemistry techniques. This research will aim to determine the composition of the major individual components that comprise the hybrid and channel catfish processing byproduct streams. Seasonal variation in the composition of the major byproduct components, including heads, frames, viscera components and skin, will be determined as the initial step in developing novel value added products from underutilized catfish waste.
