EFFECTS OF STARCH PROPERTIES ON TEXTURAL CHARACTERISTICS OF FISH BURGERS: SENSORY AND INSTRUMENTAL APPROACHES

Abstract

The objective of this study was to evaluate the effects of starch in the texture of fish burgers (surimi seafood) using starches from different botanical origins by sensory and instrumental analysis and to try to correlate the sensory and instrumental data. Three fish burger samples formulated with different types of starch were evaluated for texture by descriptive analysis and were subjected to instrumental texture profile analysis. On the basis of texture data (instrumental), formulation 3 (modified cassava starch) was categorized into a cluster representing a hard, gummy and chewy product. Sensory evaluation by a panel of eight judges categorized formulations 2 and 3 into a hard and springy product cluster. Hardness (instrumental) was positively correlated to sensory texture attributes such as hardness, springiness, gumminess, chewiness and fracturability. These sensory attributes can be used to describe fish burger that is perceived as hard during mastication.
