What is the difference between soybeans and black beans bio 35

1. Different morphological characteristics.

Morphological characteristics of black beans: black beans are kidney-shaped or round-like 1 The surface is black-red or purple-red, shiny, the seed coat is thin and brittle, and it is easy to break. The seed kernel is yellow and white, weak, sweet, flat and non-toxic.

Microscopic identification: all the cells in the outer layer of the seed coat are stone-cellular, polygonal or slightly elongated, uniform in size, thick in wall, very fine in pore groove, and large in cell cavity.

Morphological characteristics of soybean: pods are hypertrophied, oblong, slightly curved, drooping, yellowish-green, long cm, 8-15 mm wide, densely covered with long brownish-yellow hairs; Seeds 2-5, oval, nearly spherical, oval to oblong, about 1 cm long, about 5-8 mm wide, smooth seed coat, pale green, yellow, brown and black, etc., vary depending on the variety, the seed umbilicus is distinct, oval. The flowering period is from June to July, and the fruiting period is from July to September.

2. Different growth characteristics.

Black soybean growth characteristics: strong adaptability, drought tolerance, barren tolerance, salt and alkali tolerance.

Soybean growth characteristics: warm-loving, seeds begin to germinate in 10-12, 15-20 is the best, growth temperature is 20-25, flowering and pod-setting period is 20-28, pod-setting is delayed at low temperature, less than 14 can not flower, and the plant will end growth early if the temperature is too high.

3. The distribution of resources is different.

Distribution of black soybean resources: Black beans are produced in all parts of China. China's black soybean resources are abundant, the types are diverse, some precious black soybean varieties are still in production and utilization, such as Taixing black soybean in Jiangsu, belongs to the Yangtze River basin early maturing spring soybean, early maturity, high yield, strong adaptability, is still the national soybean regional test of the southern early maturing spring bean group of the control variety.

Dandong medicine black soybean is green cotyledonous black soybean, with large grains, excellent varieties and high nutritional value.

Distribution of soybean resources: Soybean originated in China. It is cultivated all over China, with Heilongjiang soybean being the most famous, and is also widely cultivated all over the world.

1. Black beans and soybeans, as two kinds of beans, are very rich in nutrients, such as protein and amino acids, fatty acids, etc., some nutrients are similar to soybeans, but the calories of black beans themselves are relatively high.

2. The content of carotene and vitamin E in soybeans is higher than that in black soybeans.

3. Black beans also contain some relatively rich, such as black bean saponins and black bean pigments have a relatively good antioxidant effect, you can choose to eat more multigrain beans in daily life, which helps to enhance physical fitness and maintain good eating habits and living habits.

4. Eating black beans can achieve the effects of nourishing the spleen and stomach, invigorating blood, diluting water and reducing swelling. Eating soybeans can achieve the effects of beauty, detoxification, cancer prevention, and promotion of body metabolism.

Difference Between Black Beans and Black Yellow Beans:

The varieties are different, black beans are leguminous soybeans, and black soybeans are a variety of soybeans, which are essentially soybeans.

The nutrients are different, black beans have higher protein content, easy to digest, and are of great significance to meet the body's needs for protein, and black beans are also high in niacin, vitamins B1, B2, B6 and trace elements such as copper, cobalt, and iron.

The function is different, the nutritional and medicinal value of black beans is similar to that of soybeans, and generally soybeans can be squeezed for oil without black beans.

Genetically modified soybeans are inactive, cannot germinate, are prone to odor, and have serious pollution to water bodies. Non-GMO soybeans have good activity, can germinate, have no peculiar smell, and have no pollution to water bodies.

Genetically modified black beans have larger grains, the color is not particularly black, and the beans are about the same size. Non-GMO black beans have small, somewhat flattened grains, light colors, and beans of different sizes.

Black beans have the characteristics of high protein and low calorie, with a protein content of more than 45%. Among them, the high-quality protein is about 1 4 higher than soybeans, ranking first among all kinds of beans, so it has also won the reputation of "the king of beans". Compared with protein-rich meat, black beans are not only not inferior, but even better, with a protein content equivalent to twice that of meat (pork, chicken), three times that of eggs, and 12 times that of milk, so it is also known as "plant-based protein meat".

The principle of transgenic technology is to introduce artificially isolated and modified high-quality genes into the genome of organisms, so as to achieve the purpose of modifying organisms. Due to the expression of introduced genes, the traits of the organism are caused to change the heritable modifications, and this technology is called artificial transgene technology.

Artificial transgenic technology is a biotechnology that transfers genes from one organism into the DNA of another organism. There is uncertainty. Commonly used methods and tools include microinjection, gene gun, electrolysis, liposomes, etc.

Transgenesis was originally used to study the function of genes, that is, to introduce foreign genes into the genome of recipient organisms (generally model organisms, such as Arabidopsis thaliana or zebrafish, etc.), to observe the traits exhibited by the organism, so as to achieve the purpose of revealing the function of genes.

First from left, genetically modified black beans, second from left, genetically modified soybeans, first from right, non-genetically modified black beans.

First, the morphological characteristics are different.

1. Black beans: oval or spherical, slightly flattened, 6 12 mm long, 5 9 mm in diameter. The surface is black or grayish-black, smooth or wrinkled, shiny, with a yellowish-white oblong umbilicus on one side.

Hard. The seed coat is thin and brittle, cotyledons 2, hypertrophic, yellow-green or pale yellow. The breath is slight and the taste is light.

2. Black soybean: similar to soybean, the surface is black and smooth, shiny, thin skin, and has a white seed umbilicus.

2. Nutrients.

1. Black beans: rich in protein, unsaturated fatty acids, phosphoesters, calcium, phosphorus, iron, potassium, sodium, carotene, vitamin B1, vitamin B2, vitamin B12, niacin, folic acid, raffinose, stachyose, choline, soy flavonoids, saponins, etc.

2. Black soybeans: containing calcium, phosphorus, iron, copper, zinc, iodine, as well as riboflavin, niacin, vitamin E, soybean sprouts are rich in vitamin C, which is a good source of minerals, trace elements and vitamins.

3. Efficacy. 1. Black beans: high protein and low calorie, anti-aging and anti-aging, enhance vitality, prevent brain aging, brighten the eyes and black hair, make the skin whiter and delicate, and prevent constipation.

2. Black soybean: nourish the spleen and kidney, benefit yin and invigorate blood, calm the nerves and eyes, promote dampness and drenching, clear heat and detoxify, nourish blood and relieve wind.

What is the difference between black beans and soybeans? Black beans and soybeans are both soy products with high nutritional value, and their rich plant protein is high-quality protein. The difference between the two is mainly in appearance, efficacy, and consumption methods.

2.Different effects: black beans have the effects of strengthening the spleen and kidneys, invigorating blood and water, dispelling wind and detoxifying, strengthening the brain, improving blood circulation, preventing and treating constipation, and intellectual.

Soybeans have the effects of skin care, water dilution, swelling, spleen strengthening, stagnation, detoxification, cancer prevention, and blood circulation. Traditional Chinese medicine believes that black beans have a good effect on the kidney.

3.The edible methods are different: black beans can be fried and eaten directly or soaked in vinegar, and traditional Chinese medicine believes that it has a good effect of tonifying the kidney, and can also be boiled in water, soup, etc.; Soybeans can be eaten as soy milk, tofu, tofu, soybean flour, bean sprouts and other soy products, or as porridge with other grains.

Most of the soy products we usually see are made from soybeans.
