Physical and chemical properties, antioxidant capacity and total phenolic content of tamarind (Tamarindus indica) seed xyloglucan component extracted using subcritical water.

AbstractTamarind kernel powder was utilized as raw material for xyloglucan component extraction. The main aims were to determine the potential of applying subcritical water in xyloglucan component extraction and to investigate effects on yield and properties of extracted xyloglucan components. Ratio of tamarind kernel powder to water for all extractions was 1:20 (w/v) with extraction temperatures of 100–200°C. Extracted xyloglucan component samples were determined for their color, pasting property, viscosity, water absorption index (WAI), water solubility index (WSI), molecular weight, antioxidant capacity, and total phenolic content. It appeared that xyloglucan components extracted by subcritical water, especially in cases where severe conditions were applied, had greater color intensity and WSI than conventional method but less holding strength, setback from trough, final viscosity, WAI, antioxidant capacity, and total phenolic content. Subcritical water extraction at 175°C provided the highest production yield of 62.28% which was remarkably higher than conventional method.
