Abstract

This study aimed to improve the quality of sterilised chicken bread spread (S-BS) fortified with silkworm pupae using binders (soy protein isolate (SP) and sodium caseinate (SC)). The characteristics of pasteurised chicken bread spread (P-BS) and S-BS were studied. S-BS was browner than P-BS, as indicated by the higher b* value. The higher total expressible fluid (TEF) in S-BS resulted in lower stickiness and spreadability values than those in P-BS, resulting in lower scores for appearance, taste, and overall preference for S-BS. Optimised types (SP and SC) and levels (0% (control), 1%, 2%, 3%, and 4%) of binders for improving S-BS quality were evaluated. The TEF of S-BS significantly decreased with increased SP and SC levels ( P 0.05). SP showed a higher capacity to reduce TEF in S-BS than SC. Increased binder levels resulted in higher shear resistance during compression than the control sample, as indicated by the higher firmness, stickiness, and spreadability. The scores for appearance, colour, texture, and overall preference of S-BS with SC were higher than those of the sample with SP. The suitable binder level was 2% to improve the S-BS quality. The highest preference was shown for S-BS with 2% SC for all sensory attributes.
