Incorporation of Minced Trout (Oncorhynchus Mykiss) Into Egg-Based Noodles

Recovering minced fish from fish frames following filleting operations is a common way to increase fish muscle yield as well as fully utilize aquatic food resources. Therefore, it is important to develop new and feasible applications for minced fish that will add value to fishery products. In this study, washed minced trout (Oncorhynchus mykiss) was incorporated at 10 and 20% flour replacement level into a conventional egg noodle formulation. Textural attributes (by TPA) of cooked noodles were evaluated. In addition, textural, functional and sensory attributes of fried noodles, a snack food item, were also evaluated. Visual color (CIE )-Lab of fresh noodles containing minced trout was less red and yellow than the control and the overall difference in color (ΔE) increased as the level of minced trout increased. Noodles incorporating 10% minced trout had cooked texture profiles similar to the control; however, there were significant decreases in hardness, gumminess and chewiness in the cooked noodles containing 20% minced trout. For the fried noodles, adding fish tended to reduce the yellow color and yielded a product with texture profiles similar to the control at a 10% substitution level. The experimental and control products were acceptable. Product preference was evenly divided between the control fried noodle and the noodle containing 10% minced trout.
