The characteristic of the Japanese rice is as follows. The rice cannot use medicine in post harvest. A distribution channel is short. I display the day when I removed rice bran. I can trace it. On this account the rice sold commonly is safe. The rice keeps it in a low temperature warehouse since harvest it. By low temperature safekeeping, it can supply delicious rice. The rice is produced in a rice factory. Impurities are removed with color sorters and various sorters. It is rice refined in this way, but the objection occurs in a ratio of 30-100ppm. As for about 90% of the objection, a consumer has a cause. The contents of the objection are other things enter, harmful insect mixture, a bad smell, bad quality, a color is strange. The rice is eaten from old days. However, there is a many people without interest in how to handle rice. I think that many people can do reduce an objection by teaching how to handle rice.
