This study was performed to investigate the effect of Gastrodia elata extract on the quality characteristics of Non-glutinous rice porridge Jochung, saccharide by barley malt. Non-glutionous Rice Porridge Jochung with 0% (NGR1), 5% (NGR2), 10% (NGR3), 15% (NGR4) and 20% (NGR5) Gastrodia elata extract were produced. Moisture content and Solids content the interaction of two factors, the pH decreased with increasing Gastrodia elata extract concentration. Reducing sugar was significantly higher in groups containing Non-glutinous Rice Porridge Jochung (NGR) with Gastrodia elata extract added than the control group, especially the 15% NGR4 addition group with 1.22±0.02 g/L. Free acidity contents were 27.27 meq/kg control and 29.67~41.03 meq/kg among the samples with p<0.001. There were significant levels of total phenolics and TEAC found for the antioxidant activity of the Jochung samples with Gastrodia elata extract added. Increasing the ratio of Gastrodia elata Extract in Jochung tended to decrease color value. The results showed that Jochung containng less than 15% Gastrodia elata Extract gave the highest scores in quality characteristics and sensory evaluation.
