Sensory evaluation of Zingiber Officinale and Tinospora Cordifolia mix powder with enhanced synergetic antioxidant efficacy by fuzzy logic and general mathematical formula

Abstract

The Zingiber officinale (ginger) and Tinospora cordifolia (giloy) are rich sources of antioxidant compounds and have been used for several decades to improve human health with relatively low side effects. The present research attempted to carry out the sensory and antioxidant activity evaluation of dried mixed paste powder of Z. officinale and T. cordifolia by establishing fuzzy logic, the newly proposed General Mathematical Formula (GMF) and the radical scavenging assay. Antioxidant activity was higher in the powder obtained in combinatorial process than the powders obtained in the separate processing of ginger or giloy. The sample containing powder, sugar and salt at 5, 5 and 1 % were more acceptable (good) and attributes generally fell under ‘important’ by both methods. Fuzzy logic and GMF results were matched perfectly for the category of samples, and quality attributes in general, and GMF method is simple and accurate for sensory evaluation.
