The formulation of white oyster mushroom (Pleurotus ostreatus (Jacq.) P. Kumm) as natural flavoring and the quality test in temperature and drying time variations

The determination of the drying temperature and time depends to the characteristic of the mushrooms. The use of low temperatures causes the mushrooms to not fully ripen, if the temperature is too high the protein contained in the mushrooms can be denatured and drying too long will change the color of the mushrooms to brown and change its taste. Research on the processing of oyster mushrooms as a raw material for natural flavoring, it is carried out to determine the quality flavoring produced through a descriptive test of the test parameters, color, aroma, taste and texture by variations the temperature 60¼C and 70¼C in drying time 6, 7 and 8 hours. The results of descriptive test of the sixth color of the flavoring have an intensity of attractive colors are light brown; Descriptive taste test F1, F2 and F5 have the intensity of the taste is rather pleasant, the umami is weak while F3, F4 and F6 have taste is quite good, umami tastes; Descriptive test of the six flavoring textures has a good intensity and; Descriptive test of the sixth aroma of flavoring has a slightly fragrant aroma intensity, the aroma of the material is not too smelly. The conclusion of the research is that temperature and drying time do not affect quality of color, aroma and texture. However, they affect the taste where the temperature 60¼C for 8 hours and a temperature of 70¼C within 7 and 8 hours have enough delicious taste with tasteful umami.
