Abstract

This study was conducted to examine contents of mineral, viscosity in the Demi-glace with added quantity of Omija extracts. Firstly, The level of mineral content in order was K, Na, P, Ca, Mg, Fe, Zn, Mn, B. The more Omija extracts, Ca, Mg, Fe, Zn, Mn, B was increased, but K, Na, P was decreased. Secondly, Viscosity of control was 538.13cP at rpm 100, and the sauce added with Omija extracts was $464.80{\sim}578.00cP$. Regardless of Omija quantity there was Psedoplastic characteristic which showed apparent viscosity was decreased even though shear rate was increased. Thirdly, Sensory characteristics of Demi-glace sauces based on preference of 5 tastes, It was founded that 2% added Omija was the best, and 1%, 0%, 3%, 5% added Omija was next in order. Finally, Sensory intensities of Demi-glace sauces based on gender and occupation of the 5 tastes : As the sourness, bitterness, hotness, salines taste of all over was Omija added quantity was many more, appeared strong intensity, it was sensory intensities of 5% Omija added sauce was the highest. But sensory intensities of sweetness, Male showed 2% Omija added sauce, Female student and cook showed control was the highest.
