But tamarind chili paste shows that pH 4.20 that is lower than tamarind chili paste mixed with karonda fruit, pH 4.49. The chemical composition of tamarind chili paste that substituted with karonda fruit 75% provides energy 237 kcal, protein 11.5%, fat 10.5%, ash 4.47% ,carbohydrate 23.7% (fiber 5.20%) and moisture content 49.33%. Moreover, tamarind chili paste mixed with karonda fruit contents iron 1.71±0.01%, Phenolic content 1.49 mg GAE/g extract and it has antioxidant activity DPPH 4.68 μmole Trolox/g extract.
