Quality Changes of Burger from Vegetable, Wheat Flour, Rice Flour with Fat Emulsion during Frozen Storage

Abstract

Animal ScienceChanges in physico-chemicals, microbial and sensory quality of newly formulated veggie burgers prepared from rice flour, wheat flour with (RW5E) and without (RI0E) fat emulsion, rice flour isolated soya protein (ISP) with (RI5E) and without (RI0E) fat emulsion were periodically analyzed during frozen storage at -18°C for 90 days. Sensorial attributes were altered with fat emulsion and rice flour wheat flour addition (p<0.05). RW5E was found to be the best sample based on sensory method. Further proximate analysis revealed that RW5E had gained 51.68% moisture, 8.38% fat, 48.33% TS, 36.84% ONF and 3.1% ash after 90 days of storage and RW5E was the best option to lessen purge and increase WHC followed by others. The results of microbial, pH and peroxide value indicated that all four products were well within the recommended standards. This study indicated that the addition of RW5E to veggie burger exhibited reasonable shelf-life and acceptable in terms of nutritional value and sensory attributes. J. Food Sci. Technol.
