いる。The quality of rice, especially its taste, depends on its variety, production area, cultivation method,
There are a wide variety of factors, including those determined by production methods such as harvesting methods, those determined at post-harvest processing stages such as drying, storage, and milling, and those affected during rice cooking. It is said that the biggest influence on the production stage is the production stage, followed by the variety.

をとる、所謂、官能試験により行われている。Traditionally, rice taste evaluation involves cooking white rice, having multiple expert examiners eat the cooked rice, and comparing various aspects such as the appearance, aroma, taste, stickiness, and hardness of the rice to be evaluated. This is done through a so-called sensory test, in which rice is repeatedly tested to see how superior or inferior it is to the standard rice used as the basis for evaluation, and the average value is taken.

あることが判明しつつある。In recent years, the composition and physical and chemical properties of rice have been scientifically measured and analyzed, and the correlation between them and the taste evaluation values obtained in the aforementioned sensory tests has been investigated, and finally, the scientifically obtained measured values. As a result of research that attempts to evaluate the quality of rice, it has been found that among the components that make up rice, those that are particularly important in evaluating the quality of rice are amylose and amylopectin, which make up the starch of rice. It is becoming clear that the ratio, protein content and water content.

。Next, we will explain how the content of each component that makes up rice affects its taste. -Koshihikari and Sasanishiki are popular brands of rice with good taste in Japan. - As an example, Table 1 shows a comparison of the protein content and amylose content of starch in several brands of white rice, including Koshihikari and Sasanishiki, with standard milling levels. . Note that the content of each component of the same brand is not always the same as shown in Table 1, and may vary depending on the geological conditions (soil quality, water quality) of the region where it was grown, and the meteorological conditions (temperature, sunshine hours,
It goes without saying that the content of each component changes slightly depending on the amount of rainfall, etc. From Table 1, Koshihikari and Sasanishiki have lower protein content and lower amylose content in starch than other general brands of rice.
第 １ 表

米の食味に大きな影響を及ぼすこととは別に、白米の含
水率も米飯の粘度、硬度に関連して食味に大きな影響を
及ぼす。Table 1 (Protein content indicates weight ratio; amylose content indicates ratio to 100% starch.) As mentioned above, protein content and amylose content ratio in starch have a large effect on the taste of rice. Apart from this, the moisture content of white rice also has a great effect on the taste, as it relates to the viscosity and hardness of the rice.
白米の含水率が１５％程度の場合、水中に浸漬しても白

めて小さい）との水分差による体積歪みによって瞬間的
に亀裂を起こし、炊飯すると、その亀裂の割目から澱粉
粒子が吹きでて噛み応えも粘りもないべとついた低品質
の米飯となる。If the moisture content of white rice is around 15%, the rice will not crack even when soaked in water and will be cooked into perfect rice grains. Water absorption progresses rapidly from the ventral side of polished rice (where there are relatively many intercellular spaces for water to penetrate) to the endosperm, causing instantaneous cracks due to the volume strain caused by the difference in water content with the dorsal side (where the intercellular spaces are extremely small). When rice is raised and cooked, starch particles blow out from the cracks, resulting in sticky, low-quality rice that is neither chewy nor sticky.
また、砕米も同様に一気に吸水するのでべたついた米飯
に炊き上がり、しかも米飯が崩れているため噛み応えも
粘りもない低品質の米飯となることが知られている。It is also known that broken rice similarly absorbs water all at once, resulting in sticky cooked rice, and the rice is crumbly, resulting in low-quality cooked rice that lacks chewiness and stickiness.
一方、米の生産者にあっては、政府の水分検査の上限で

とが知られている。On the other hand, rice producers tend to supply rice that is too dry because they are overly concerned about exceeding the government's upper limit of 15% for moisture testing. It is known that 0.5% to 1.0% of water is lost from rice grains.
そこで、米粒（玄米、白米）を水（水蒸気）と接触させ
、米粒の含水率を１５％に維持する調湿が行われるので
ある。しかし、古米とか元来食味の悪い米は細胞間隙が
狭くなっており、浸漬しても米粒の隅々まで吸水せず、
炊飯した場合、α化程度が低く食味の劣る米飯となる。Therefore, humidity control is performed by bringing rice grains (brown rice, white rice) into contact with water (steam) to maintain the moisture content of the rice grains at 15%. However, in old rice and rice that has a poor taste, the intercellular spaces are narrow, and even when soaked, water cannot be absorbed into every corner of the rice grain.
When the rice is cooked, the degree of gelatinization is low, resulting in rice with poor taste.

わち硬さで除し、この値をバランス度とするもので、一
般にバランス度の大きい方が食味が良いといわれる。The texturometer uses a plunger to repeatedly press and pull rice grains placed in a saucer, matching the chewing speed of humans, and calculates this value by dividing the tensile force, or stickiness, by the pressing force, or hardness. It is a measure of balance, and it is generally said that the higher the balance, the better the taste.

噴霧するなどの手段により米粒表面から内部に吸収させ
るようにしても、炊飯時に若干の溶出はあるが、それな
りの効果を得ることはできる。Furthermore, even if the additive for rice grains is dissolved in water and sprayed to absorb it from the surface of the rice grains into the rice grains when conditioning the humidity of the rice grains, some effects may be obtained, although some elution may occur during cooking. I can.
前記のように米粒の調湿時に水に前記米粒用添加剤を溶
かして噴霧せずにあらかじめ酸を添加しておいて後に調
湿することにより、米粒に確実に付着させることができ
ると米粒内部へ浸透させることもできる。As mentioned above, when conditioning the rice grains, instead of dissolving the rice grain additive in water and spraying it, by adding acid in advance and then conditioning the humidity, it is possible to ensure that it adheres to the rice grains. It can also be infiltrated.
その他に、あらかじめ一定量の前記米粒用添加剤を米粒
内部に浸透させるか、または米粒表面にコーティングし
た米粒を準備し、計Ｍ包装時または炊飯時に前記処理を
施していない白米粒と混合して炊飯しても応分の効果を
得られる。In addition, a certain amount of the rice grain additive may be infiltrated into the interior of the rice grains or coated on the surface of the rice grains, and then mixed with untreated white rice grains during packaging or cooking. Even if you cook the rice, you can get the appropriate effect.
不揮発性の酸は炊飯後食べる際に異臭を発散させること
が少なく、食味の向上を阻害することが少ない。Non-volatile acids are less likely to emit off-flavors when eaten after cooking, and are less likely to impede improvement in taste.
