Question 1: How to identify the quality of rice. The quality of rice in my country is graded based on processing accuracy. Processing accuracy refers to the degree of skin retention on the back groove and grain surface of rice. According to the national standard "Rice GB1354-86", rice is divided into four grades according to its processing accuracy: special grade, standard first grade, standard second grade, and third grade.

The classification of rice is closely related to the classification of rice. In my country and the international market, rice is usually divided into three categories: indica rice, japonica rice, and glutinous rice based on grain shape and grain quality. The details are as follows:

(1) Indica rice

Indica rice is made from indica non-waxy rice and is called indica rice. Rice grains are slender or oblong in shape, with the length of the longest being more than 7 mm. After cooking, the rice yield is high, the stickiness is low, the rice is brittle and easily broken during processing, the cross-section is oblate, and the color is white and transparent. There are many, including translucent and opaque. According to the rice harvest season, it is divided into early indica rice and late indica rice. The grains of early indica rice are thick and short, pinkish-white, with a large white belly, rich in powder, fragile and brittle texture, less viscous than late indica rice, and of poorer quality. Late indica rice has slender and slightly flat grains, fine texture, generally transparent or translucent, smaller belly white, more hard grains, greater oiliness, and better quality.

In the international market, indica rice is divided into long-grain rice and medium-grain rice according to the length of the rice grains. Long-grain rice is slender in shape, with a length-to-width ratio generally greater than 3. It is generally waxy white, transparent or translucent. It is brittle and oily. It is soft, tough but not sticky after being boiled. It has a delicate and delicious taste. It is the best quality among indica rice. Qimei and Si Miao produced in Guangdong Province of my country and Blue Crown from the United States are all long-grain rice.

Medium-grain rice has an oblong shape and is slightly thicker than long-grain rice. The length-to-width ratio is between 2 and 3. It is generally translucent, has a white belly, and is more powdery. It becomes loose after cooking and tastes bad when eaten. Rougher. The quality is not as good as long grain rice. Most of the rice produced in my country's Hunan, Guangxi, Jiangxi, Sichuan and other provinces is medium-grained. American Zinais is also a medium-grain rice.

According to the length of rice, Thai rice standards are divided into four types: extra long (above 7 mm), long (6.6~7 mm), medium (6.2~6.6 mm) and short (below 6.2 mm). .

(2) Japonica rice

Japonica rice is rice made from japonica-type non-waxy rice. Rice grains are generally oval or round. The rice grains are plump and thick, the cross-section is nearly round, the ratio of length to width is less than 2, the color is waxy white, transparent or translucent, the texture is hard and tough, the viscosity and oiliness are high after cooking, soft and delicious, but the rice yield rate is low .

According to the harvest season, japonica rice is divided into early japonica rice and late japonica rice. Early japonica rice is translucent, has larger white belly, fewer hard grains, and poor rice quality. Late japonica rice is white or waxy white, with small belly white, many hard grains, and high quality.

Japonica rice is mainly produced in North my country, Northeast China and Southern Jiangsu. The famous Xiaozhan rice and Shanghai white japonica rice are all excellent japonica rice. The yield of japonica rice is much lower than that of indica rice.

(3) Glutinous rice

Glutinous rice, also known as glutinous rice, is milky white, opaque, and transparent after cooking. It has high stickiness and low swelling. It is generally not used as a staple food. It is mostly used to make pastries, rice dumplings, Yuanxiao, etc., as well as raw materials for making wine.

Glutinous rice can also be divided into indica and japonica. The grain shape of indica and japonica rice is generally oblong or elongated, milky white and opaque, and some are translucent and sticky. Japonica and glutinous rice are generally oval, milky white and opaque, and some are translucent and sticky. The rice quality is better than that of indica. Japonica rice.

Among the above three types of rice, indica rice and japonica rice are particularly important, and indica rice has the largest trade volume. Southeast Asia, Africa and Latin America mainly consume indica rice, with long-grain rice being the most popular. People in Japan, North Korea, Italy and other countries like to eat japonica rice. In Europe, both indica and japonica rice are consumed.

In the international market, rice is classified as follows according to the degree of rice processing and processing methods:

(1) Brown rice

Rice is processed Brown rice is a complete fruit after only grinding off the chaff. Brown rice generally requires further processing before it can be eaten. Brown rice is not heavily traded.

(2) White rice

Brown rice continues to be processed, and the cortex and embryo (i.e. fine bran) are ground away, leaving basically only the endosperm, which is the white rice or rice we usually eat. Rice in my country is divided into four levels: special grade, standard first grade, standard second grade, and standard third grade.

Thai white rice refers to non-glutinous brown rice that has been processed and milled to remove the hull. ***It is divided into 11 levels, including 100A, 100B, 100C, 5, 10, 15, 20, 25 (upper), 25, 35, and 45.

(3) Parboiled rice

Parboiled rice is rice made by soaking rice in hot water, heating it with steam and drying it, and then grinding it. Parboiled rice has enhanced rigidity, and the rice yield rate is higher than that of ordinary rice; the nutrients in the bran are absorbed by water...gt;gt;

Question 2: Which unit should be responsible for investigating and handling problems with rice quality? 1. Industrial and Commercial Bureau. 2. Food and Drug Administration 3. Technical Supervision Bureau

Question 3: Is there a quality problem if the rice is more watery? Let’s put it this way. If the rice you make is made of new rice, then you can add water. Put less because new rice does not absorb water. If the rice is made with old rice, add more water than the normal amount, because old rice is dry and easy to drink water. Therefore, the water content of rice has nothing to do with the quality, but has something to do with the newness of the rice.

Question 4: There is a quality problem with the rice I bought, but the manufacturer won’t solve it. How to expose the local netizen group, real pictures, related quality problems, and send netizen links. The power of the Internet is powerful, and the speed of dissemination is Very fast, this kind of real spread, the manufacturer will not be far away.

Question 5: Is it considered a quality problem if there are rice worms in the rice? If the rice is left out for too long, there will be worms.

If there were worms when you bought it,

The description has expired.

It’s a quality issue. Request a return.

Question 6: Raw rice is not a potentially harmful food. Like melon seeds and peanuts, it is easy for children to inhale the trachea and cause danger.

Question 7: Are there any serious quality problems with Hunan rice? All refined rice has problems and is the main culprit of modern diseases. It is recommended that you eat whole grains (sweet potatoes, rice with rice skin)

Question 8: Rice starts to crack after being taken out of the package. What's going on? Is it a rice quality problem? How to identify good rice? Thank you. The grains are plump, no broken rice, long in length, sweet and delicious when cooked, you can tell with a kiss

Question 9: What are the rice brands in my country? Rice is divided into three categories: indica rice, japonica rice and glutinous rice. Indica rice is made from indica-type non-waxy rice, and the rice grains are generally oblong or elongated. According to the harvest season of indica rice, it is divided into two types: early indica rice and late indica rice. Which brand of rice is more delicious, and what are the delicious rice brands?
