This study determined the effects of addition of medicinal herb extracts (Zanthoxylum piperitum extract(TZ), Acanthopanax sessiliflorus(TA), Panax ginseng(TP), Cinnamomum lureitri Nees(TC), Angelica gigantis radix(TAG) and Crataegii fructus extract (TCF) to teriyaki sauce with regard to taste and health benefit. After adding the medicinal herb extracts to teriyaki sauce, moisture content was found to be inversely proportional to the viscosity. The sauce with Panax ginseng extract(TP) had lowest sweetness, but highest salinity. The results showed that the sauce with Korean herb extracts had lower salinity content. In terms of colour value, the sauce with Crataegii fructus extract(TCF) had much higher lightness, redness, and yellowness than sauce prepared with other herb extracts. It had the strongest acidic taste and lowest pH. Sensory evaluation test revealed that the sauce with Anthoxylum piperitum extract(TZ) was the most preferred sauce among all the sauces tested. The degree of brown color of teriyaki sauces was correlated positively with taste preference(r=.570, p<0.01) and overall preference(r=.505, p<0.01).
