The invention relates to a method for preparing phosphatidyserine. The method for preparing phosphatidyserine comprises the following steps of mixing phosphatidylcholine or natural phospholipid containing phosphatidylcholine with tween-80, L-serine, calcium chloride, buffer solution and phospholipase D, and stirring and reacting the above materials at 35-45 DEG C for 8-10h; separating out the crude products from reaction and floating, carrying out centrifugal separation on the aqueous phase and crude products, washing the crude products subjected to separation and carrying out centrifugal filtration; adding the crude products subjected to centrifugal filtration into absolute ethyl alcohol for immersing, stirring, and carrying out centrifugal filtration; and carrying out vacuum drying on the products subjected to centrifugal filtration to obtain the phosphatidyserine. The invention aims to provide a new method for preparing phosphatidyserine to solve the problems that in the prior art, the byproduct of phosphatidic acid is large in amount, the conversion rate is unsatisfactory and the product cost is high.

The invention relates to the technical field of agriculture, and in particular relates to a wall-mounted agricultural planting frame intelligent environment management and control system. The system includes a main frame, a hanging curtain, a circular scale net, a water control system, a light control system, a temperature control system, and a retractable curling module; a plurality of planting units are arranged on the hanging curtain, a plurality of planting boxes and light modules corresponding to the planting boxes are arranged on each planting unit, and a planting frame is provided witha humidity detection device, a brightness detection device and a temperature detection device, and when the humidity, temperature, and illumination do not meet requirements, management and control isperformed automatically. The intelligent environment management and control system provided by the invention has the beneficial effects that the wall-mounted agricultural planting frame intelligent environment management and control system utilizes sensors to collect environmental factors, and performs intelligent environmental management and automatically manage light, water, and temperature according to environmental management and control strategies; light is supplemented at nights and the temperature is raised automatically, so that the production efficiency of plants is improved, and theyield is improved; and a physical method is adopted to kill insects, thereby eliminating the use of pesticides, and ensuring the greenness and health of planted products.

The invention relates to a method for extracting and purifying phytosterols from corn silk, which comprises the following steps: 1) adding 1 g of crushed and dried corn silk to 2-6ml saponification liquid, saponifying at 85±10°C for 2-4 hours, and then Add absolute ethanol for ultrasonic extraction for 0.5-1h, centrifuge after ultrasonic extraction, take the supernatant and rotary evaporate to obtain the crude extract; the saponified solution is potassium hydroxide ethanol solution with a concentration of 2-5mol / L; 2) the crude extract is used After solvent extraction, it is recrystallized from ethyl acetate to obtain the finished product. The method of the invention has simple operation, short technological process, low production cost, high product yield and high purity (up to 83%), and opens up a new way for the full utilization of waste resource corn silk.

The invention discloses a production method of freeze-dried instant egg powder. The production method of the freeze-dried instant egg powder comprises the following steps of adding edible oil into eggliquid during processing process of the egg liquid, wherein the addition amount of the edible oil is 0.1-1% in percentage by mass, and carrying out stirring by using a stirrer for three minutes so asto obtain a uniform mixture; and then, containing the mixture in a plate, carrying out steaming, and carrying out freeze-drying. In addition, the production method of the freeze-dried instant egg powder is also capable of reducing internal bubble production during the steaming-curing process of the egg liquid, so that the freeze-drying rate can be improved.

The invention discloses ceramic quartz paint. The ceramic quartz paint is prepared from, by weight, 3-7% of inorganic pigment, 58-62% of quartz sand, 10-15% of water, 18-25% of acrylic emulsion, 0.2-0.5% of cellulose, 0.1-0.2% of bactericide, 0.6-0.9% of film forming matter and 0.6-0.9% of silica sol, and the total percentage of the components is 100%. The invention also provides a preparing process of the ceramic quartz paint. According to the preparing process, raw materials are matched according to a scientific and refined ratio for production, and regulation is conducted for each step in strict accordance with technical requirements, so that the optimum state of a product is guaranteed. The environment-friendly, healthy and pollution-free principle is followed during production, environment friendliness of the preparing process is guaranteed, and the national policy requirement for green building materials is met.

The invention relates to a method for preparing high-purity nano-crystalline cellulose from textile plants and relates to the utilization of textile plants. The method comprises the following steps: 1), after being crushed and screened for purification, textile plants are added into a sulfuric acid aqueous solution for treatment, so as to dissolve out glycan, and then through washing and squeezing, a preprocessed fibrous material A is obtained; 2), the fibrous material A obtained in the step 1), magnesium oxide and water are added into a reaction kettle, oxygen is introduced, then washing and squeezing are performed after reaction, and a crude fibre B is obtained; and 3), the crude fibre B obtained in the step 2), hydrogen peroxide and water are added into a reaction kettle for reaction, after reaction, the high-purity nano-crystalline cellulose can be obtained through washing, squeezing, diluted homogenizing, high-pressure homogenizing and drying. Hemicelluloses and lignin in the textile plants are effectively removed; further the purity and the whiteness of the cellulose are further improved; not only is an environmental physical method adopted for preparing nano-crystalline cellulose, but also high purity cellulose can be made from the textile plants in a sulfur-free and chloride-free way, and the method can be well applied to the fields of foods, medicines and the like.
