Abstract

Goshtaba is a restructured meat product of Kashmiri wazwan prepared from meat emulsion with added fat (20 %), salt, spices and condiments and cooked in the curd. The present study was undertaken for the development of low fat goshtaba with the addition of xanthan gum as a fat replacer and was evaluated for proximate composition, pH, colour, lipid and protein oxidation, texture, microstructure and sensory properties. Low fat goshtaba formulations containing xanthan gum were higher in protein and moisture contents but, lower in fat content and pH value than the high fat control (p < 0.05). Colour evaluation revealed that high fat goshtaba had significantly higher L* value, but lower a* value than its low fat counterparts (p < 0.05). The significant decrease of TBARS values, protein carbonyls and loss of protein sulphydryl groups in low fat goshtaba formulations reflects the potential antioxidant activity of xanthan gum (p < 0.05). Hardness was significantly higher in high fat control but, cohesiveness, gumminess, and chewiness did not show any significant difference. Springiness increased with the increasing concentration of xanthan gum (0.5-1.5 %) and was higher in low fat product containing 1.5 % xanthan gum. SEM results indicate that xanthan gum lead to formation of an additional gel network which holds more water. Sensory evaluation revealed that goshtaba product with 0.5 % xanthan gum had quality characteristics that were similar to the control product containing 20 % fat.
