After the snow has turned solar, the northeast wind has become a frequent visitor. Therefore, the diet should follow the principle of “the cold is warm and the deficiency is the deficiencyâ€. Food and nutrition should be based on nourishing the liver and kidneys, clearing away the inner fire, and eating warm or hot. Food to improve the body's ability to withstand cold. According to experts, some black foods are actually better choices during this season. Let's take a look at what is best for them after the solar terms.
Black food
Within the five internal organs, black food is most beneficial to the kidneys. In winter, we eat some nourishing foods. Black food is the first choice. The following Xiaobian recommends some black food for you.
black rice
Black rice is a treasure of rice, known as “Gongmi†and “Longevity Rice†and has a special nutritional value. The reason why the color of black rice is different from other rice is mainly because its outer skin contains anti-aging anthocyanin pigment. The deeper the color of rice, the stronger the anti-aging effect of epidermal pigments. In addition, this pigment is also rich in flavonoid active substances, equivalent to five times as much as white rice, which is of great benefit in preventing arteriosclerosis.
Long-term consumption of black rice can not only promote sleep, but also treat dizziness, dizziness, anemia, white hair, eye diseases, and weakness in the waist and legs. In addition, black rice also has a certain effect on blood, pain, and internal and external injuries. Maternal eat more black rice food, the body can be restored as soon as possible, also has a good effect on children's white hair.
In winter, nourishing the body to eat black rice can be matched with other foods. Black rice can be cooked with white rice, or porridge with walnut, jujube, white fungus, lotus seeds, etc. Because the outer layer of black rice is a kind of tough seed coat, so it needs to be soaked beforehand, then it can be boiled and eaten, otherwise it will easily cause indigestion. In addition, soaked rice must be cooked together with rice to preserve the nutrients.
Squid
In the cold and windy winter, the squid has a lot of fat and fat, and it is especially delicious, so folks say "Winter, Summer and Summer." The carp is delicate in meat quality, sweet in flesh and high in nutritional value. It contains 13 grams of protein per 100 grams of meat and 11 grams of fat, and contains a lot of calcium, phosphorus, iron and other minerals. The medicinal value of squid is extremely high, its sweetness, flatness, warmth, into the stomach, kidney, and in the tonic, dehumidification, water, tonic win, warm stomach to eat, make up the effect of angry.
The protein contained in squid is excellent, complete, easy to digest and absorb, and it is a good source of protein for liver and kidney diseases and cardiovascular and cerebrovascular diseases. Regular food can enhance disease resistance, prevent and treat hypertension, arteriosclerosis, coronary heart disease, and is an excellent food for liver, kidney, chronic bronchitis and other diseases. Regular consumption can supplement nutrition and enhance disease resistance.
Because of its low fat content, squid is fresh and not fatty, making it ideal for women who want both beauty and fat. Carp contains a comprehensive and high-quality protein, which can play an important role in strengthening the elastic fiber structure of the skin. Regular consumption can improve the condition of rough skin, and it can eliminate the wrinkles caused by stress, lack of sleep and other factors.
Preparation of Fenebute
1. Prepare the first intermediate
Benzaldehyde and ethyl acetoacetate into ethanol, stir at room temperature under the catalysis of organic alkali reaction with filter cake filtration after 45 ~ 50 h, after the completion of the filter with ethanol elution filter cake, dry cake solids, then ethanol filtrate concentrated to a quarter of the original volume, to cold, concentrate filtering alcohol washing, solid, merging two solid is the first intermediate; The mole ratio of benzaldehyde, ethyl acetoacetate and ethanol is 1:2.5 -3:12-15.
2. Prepare the second intermediate
The first intermediate is added to the mass concentration of 20% sodium hydroxide solution, and the reaction is stirred at 85-90°C for 2-5 hours. After filtration, the filter cake is used for filtration. After filtration, the filter cake is washed, the filtrate is combined and cooled, and the filtrate is cooled by stirring for 3h. Solid second intermediate; The mass ratio of the first intermediate to the sodium hydroxide solution is I: 1.8-2.0;
3. Prepare the third intermediate
The second intermediate was dissolved in pure acetic anhydride solution for reflux 3 ~ 5h. After the reflux, the acetic anhydride was concentrated and dissolved with toluene. After the dissolution, ammonia water was added, and the reaction took place at 60_65°C for 1 ~ 1.5 h. Filtrate, wash and dry the precipitated solid to get the solid third intermediate; The mass ratio of the second intermediate, pure acetic anhydride solution, toluene and ammonia water is 5:1-1.2:0.5-0.8:0.5-0.8;
4. Prepare Finebute
The third intermediate was dissolved in 25% sodium hydroxide solution and cooled to _5°C ~ 10°C. After cooling, sodium hypochlorite was added slowly within 15-20min for 1h reaction, followed by ice bath reaction of 0.5 ~ 1.5 h and water bath reaction of 0.5 ~ 1.5 h. Finally, the temperature was gradually increased to 60 ~ 80°C for 1-5 h, and the reaction was cooled again after completion. After cooling, hydrochloric acid was added in the ice water bath to adjust the PH to 2, and the decolorization was stirred at room temperature. After filtration, sodium hydroxide was added in the ice water bath to adjust the PH to 6-7, and the cooling was stirred for 2 hours. The mass ratio of the third intermediate, sodium hydroxide solution and sodium hypochlorite is 1.0:0.8-1.0:1.0-1.1.
