Abstract: PURPOSE:To estimate the mixing ratio of the mixed rices of the different kinds which are to become the intended taste value accurately by determining the intended taste value, investigating the value on the diagram corresponding to this taste value, and finding the mixing ratio of the rices based on the value on the diagram. CONSTITUTION:The contents contained in rice 1 undergo quantitative analysis with a taste meter, and a taste value FA of the rice 1 is obtained. The contents contained in rice 2 undergo quantitative analysis with the taste meter, and a taste value FB of the rice 2 is obtained. Then, the mixing ratios of the rice 1 and the rice 2 are changed for several kinds, and the tastes are tested. Thus, the respective tastes are obtained. The results are plotted on the diagram by interpolating the part between the points. For example, when the mixed rices of the different kinds whose taste value is FA+B are required, the mixing ratio is read from the applicable coordinates on the diagram. Thus, the mixing ratio between the rice 1 and the rice 2 alpha:beta is obtained. The alpha:beta is the mixing ratio of the rices by which the taste value FA+B is obtained. The rices are mixed based on the mixing ratio. In this way, what mixing ratio gives the intended taste value can be accurately estimated.
