い。2. Description of the Related Art There is known a form in which the grain quality and taste are determined at the time of receiving a cargo, and the grains are sorted for predetermined quality or taste and post-processed (Japanese Patent Laid-Open No. 3-2).
No. 01941). However, in the above-described conventional technology, the appearance quality can be detected by optical means with respect to the quality, but no consideration is given to the germination rate having a high correlation with the taste.

食味を落す。[0003] The germination rate or germination ability of brown rice is generally considered to be higher as phthalate dehydrogenase is present in the embryo, and the degree can be confirmed by TTC (triphenyltetrazolium chloride) color reaction. The germination rate is correlated with the degree of propagation of heat-resistant bacteria that affect the taste of cooked rice (FIG. 2 (a)). Since the germination rate increases as the temperature increases, the germination rate tends to increase as the degree of whitening increases. (B)
After cooking, it increases with time ((c) in the figure). If it exceeds a certain number due to the increase after cooking rice, it smells rancid and loses its taste.
【０００４】したがって、発芽率の高い方が食味はよい
ことが知れるのである。Therefore, it is known that the higher the germination rate, the better the taste.

Focusing on the germination rate as a taste-influencing factor, the aim was to produce high-quality rice, and the following technical measures were taken. That is, brown rice having at least the same level of germination rate or germination ability is stratified to form a brown rice blending method.

Here, in order to estimate the germination rate of brown rice, near infrared analysis of the sample is performed in parallel with observing the actual germination rate of a predetermined sample separately. The germination rate is calculated by creating a calibration curve by calculating the absorbance for each wavelength in the near-infrared region, and calculating the germination rate by accumulating the absorbance characteristics for a plurality of different known germination rates. Can be estimated. For example, as shown in FIG. 4, the absorbance (LOG1 / LOG1) of brown rice having different (known) germination rates in the near infrared region.

る。In order to take out brown rice stored in a predetermined stratified tank and perform rice polishing, the controller 8 outputs a shutter open signal (not shown) to a discharge portion of the stratified tank. Brown rice in a predetermined tank falls onto a discharge conveyor 11 and is discharged outside the machine via a two-way switching valve 12 and a measuring device 13. The procedure for producing the blended rice is as follows. The two-way switching valve 12 is switched to supply brown rice from a predetermined stratified tank, for example, the tank 9a having an abnormal germination rate of 75%, to the blending tank 16. Brown rice from different stratification tanks 9b is similarly supplied to the blending tank 16 and is stirred and mixed by the lower blending device 17. The blended rice that has been stirred and mixed is used in the subsequent blended brown rice storage tank 21a,
It is sent to one of 21b and 21c and stored. At this time, different brown rice groups having the same germination rate division, that is, stratified tanks 9a, 9b, 9c, or stratified tanks 9d, 9e, 9f,
Alternatively, 9j and 9k are blended respectively.

Is easy. In addition to the germination rate during blending, the combination of brown rice with a high protein content and brown rice with a small amount promotes good taste.
