However, it may be carried out for other assorted grains, or the grain before the quality determination. May be targeted. The same applies to the hygiene evaluation device 3.

値に頼るものでないから便利である。Further, the hygiene degree measuring means 3 has a structure in which the number of microorganisms can be estimated from the ATP concentration in the above-mentioned embodiment, but it may have a form capable of measuring the residual pesticide. In addition,
The internal quality measuring means 2 is configured such that the taste evaluation value is calculated by near-infrared spectroscopic analysis of the components of grain and the like, and the measurement value is an absolute evaluation value. However,
Grain harvest and its quality are easily affected by the weather conditions of the year, and for example, the amount of sunshine and the cumulative temperature affect the components. Therefore, according to the conventional method, the score and the like for evaluating grains with different meteorological conditions greatly depend on the year, and are not suitable for showing relative superiority or inferiority in the year. Therefore, by setting the taste evaluation value in consideration of the above-mentioned weather conditions, it is possible to evaluate rice under different weather conditions under the same conditions. For this reason, for example, as shown in FIG. 5, an evaluation value line that is established in a predetermined relationship is obtained in a three-dimensional map composed of the amount of sunshine, integrated temperature, and taste evaluation value, and the sunshine of the grain to be measured is obtained. The position on this line is determined from the amount and the integrated temperature, and the taste evaluation value corresponding to that point is determined.
Although this value is the taste evaluation value of absolute evaluation, the highest value of the relevant year is calculated by the same method. This is assumed to be 80 points. That is, this year means that the absolute evaluation value of 80 points is the highest even if the weather is bad and the cultivation is good compared to the usual year. Then from the 3D map in the same way 60
When you get a score for a point, the relative score for this year is 75
This is the point (Fig. 6). With such a calculation, the relative evaluation value for the relevant year can be calculated,
This is convenient because it is possible to obtain a relative evaluation score out of a perfect score and not rely on extreme numbers.

より明確となる。In general, the degree of fatty acid is used for determining old rice, and the determination of old rice can be further clarified by examining the relationship between the degree of fatty acid and the amount of maltose. That is, the degree of fatty acid P 1 (when the degree of fatty acid increases, when brown rice is whitened and its iodine coloration starts to decrease on a plane in which the horizontal axis is the degree of brown rice fatty acid and the vertical axis is the amount of brown rice maltose Since fatty acid enters the helical structure of starch, iodine coloration tends to decrease), and fatty acid content measurement limit value P 2 (about 80).

If areas A, B, C, and D are divided by the vertical axis passing through, A is evaluated as new rice and D is evaluated as old rice. In addition, it becomes A, B, C, D in order from the new rice. Conventionally, it is difficult to find a qualitative difference when only the degree of fatty acid is used as the measurement of old rice, but the judgment of old rice becomes clearer by adding the judgment of the amount of maltose.
