Effect of inulin on physico-chemical, sensory, fatty acid profile and microstructure of processed cheese spread

Abstract

To develop a functional processed cheese spread (PCS) different levels of inulin (0, 4, 6 and 8%) addition into PCS was studied with its physico-chemical, sensory and fatty acid profile and micro-structural quality. As the level of inulin addition increased moisture, a_w and titratable acidity, decreased. At the highest level of inulin addition (8%) sensory panelists reported a significant decrease in total sensory score. PCS with 6% insulin was found to have optimum from quantity. The addition of inulin in cheese spread decreased both total saturated fatty acid and unsaturated fatty acid and in unsaturated fatty acid, mono unsaturated fatty acid decreased; however, polyunsaturated fatty acids increased as compared to the control. Scanning Electron Micrograph of PCS containing insulin showed uniform distribution of insulin with diameter ranged 4–10 µm in the protein matrix.
