Abstract

|
The purpose of this study was to investigate the appropriate water content in high omega-3 fatty acid Saury nuggets for the desirable texture. The approach was made with adding water and onion at various levels (0~20%). The main ingredients of the nuggets included saury mince, mild pizza cheese, and hydrated textured soy protein concentrate. The formulated products were molded (dia. 4.5, thickness 1.5 cm, 20 g), lightly battered, and flash fried for 4 min. at 160oC, and then frozen until tested. The frozen nuggets were cooked at 165oC and subjected to sensory evaluations, texture analysis, and water content analysis during warming (0~60 min), as well as assessments of acid, peroxide, and TBA values (during 10 days of storage at 24oC). In the sensory evaluation, preference for texture was highest in the nuggets made with a 15% onion level. The hardness of the nuggets increased with increasing onion level. Moisture content was highest in the nuggets made with a 20% water level. Changes in hardness during warming (0~60 min) of Saury nuggets containing various water and onion levels increased in nuggets made with the 20% water level. The acid, peroxide, and TBA values of the Saury nuggets made with herbs and oriental herbal extracts decreased up to 10 days of storage.
