Physicochemical, textural, sensory characteristics and storage stability of goat meat patties extended with full‐fat soy paste and soy granules

Abstract

SummaryThe performance of full‐fat soy paste (FFSP) with reduced beany flavour made by simple processing technology was compared with the commercially available textured soy granules in goat meat patties. Addition of soy proteins (soy paste and soy granules) did not significantly affect the emulsion stability and product yield. Shrinkage of patties with soy paste was comparable with control. A significant (P < 0.05) reduction in redness and increase in yellowness of patties was due to addition of soy proteins than in control. Patties with soy paste had comparable but slightly higher total lipid and cholesterol content with that of control but significantly (P < 0.05) higher than patties with soy granules. Lower force was required to compress or shear the sample, as hardness decreased in soy‐added patties. Flavour and overall acceptability scores between control and patties with soy paste did not differ significantly, whereas patties with soy granules were rated significantly lower. The patties remained stable with minor changes in physicochemical, microbiological and sensory quality during refrigerated storage (4 ± 1 °C) for 20 days. It is concluded from this study that FFSP had potential application similar to commercially available textured soy granules in comminuted meat products.
