1. Look at the appearance of the soybeans. Good soybeans require full, neat, uniform kernels with no mold, no broken valves, no bug eyes, no defects or hanging silk, which is a good soybean. We won't say much about the appearance. You can basically recognize the appearance of soybeans at a glance.
2. Look at the color of the soybeans. The seed coat is brightly colored and the skin is clean. Dull color is worse. Let's mainly talk about color. According to our experience in growing soybeans, the color of soybeans will be lighter after being stored for a period of time, and there is no right or wrong opinion about whether it is yellow soy or white soy. Because the color of soybeans is on the one hand linked to the variety, and on the other hand, it is linked to post-harvest storage. Some varieties of soybeans are more yellow and others whitish. The skin of soybeans can alsomay turn white if exposed to sunlight for a long time after receiving the goods. Therefore, the color of the soybeans is not very important when purchasing soybeans. However, if the soybean is red, black or green, we generally don't buy it. Red means the soybeans are old, black means there are lesions, and green means the soybeans are not fully mature.
3. Look at the humidity. We use a hard object to crush the soybeans, and the sound is crisp. Broken soybeans are crumb-shaped, which means that the soybeans are relatively dry, they are soybeans with too much moisture, so it is. it is not recommended to purchase them.
4. Look at the flesh color of the soybeans. White meat indicates a soy with more protein, while yellow meat indicates a soy with more protein.us of oil. Of course, we are just trying to popularize this issue of flesh color, and it has no practical significance. Because we compared and found that the soybeans we eat at home have no practical significance, whether they contain more oil or more protein. Why do you say that ? Since high oil content and high protein content are relative terms, large-scale processing companies will specifically select soybeans for oil or protein extraction. Due to the large quantity, a little difference can mean a lot of money. As for our soya, there is no need to worry about this difference, it makes no sense.
Soy is soy.
Soybean is included in soybean, which is a type of soybean. Soy is a general term. Beans can be divided into soybeans and other legumes. Soy is the prmajor legumes, including soybeans, black beans, green beans, brown beans and bicolor soybeans. Other beans are miscellaneous beans, including broad beans, peas, mung beans, kidney beans, etc. Soybeans are the seeds of the legume soybean, and soybeans are one of the protein-containing grains.
The height of the soybean plant is approximately 30 to 90 centimeters. The stem is thick and erect, and the stem is densely covered with long brown bristles. There are generally 3 leaflets on the leaves, the stipules are broadly ovate, acuminate and the petiole is 2 to 20 cm long. Racemes, usually with 5-8 flowers, flower color is purple, lilac or white. The pods are plump, oblong in shape, yellow-green in color and densely covered with long brown hairs.
Morphological characteristics of soybean:
Annual grass, 30 to 90 cm high. The stem is large, erecte, or the upper part is almost sinuous and the upper part is more or less ribbed.Densely covered with long brown bristles. The leaves generally have 3 leaflets. The stipules are broadly ovate, acuminate, 3 to 7 mm long, veined, ** pubescent, and the petioles are 2 to 20 cm long, when young they are slightly pubescent or ribbed. leaflets papery, broadly ovate, almost round or elliptical-lanceolate.
The upper one is larger, 5-12 cm long, 2.5-8 cm wide, acuminate or almost rounded apex, rare and blunt shape, with a small convex tip, wide base in wedge or round shape, lateral leaflets are smaller, obliquely ovate, usually strigose on both sides or glabrous below, with 5 lateral veins on each side. The stipules are lanceolate, 1 to 2 mm long, and the petiole is 1.5 to 4 mm long. bristles, short clusters with few flowers and long clusters with manyshady flowers.
