The invention discloses an extraction method of rose flavonoids, which comprises the following steps: S1, crushing selected dry Hetian rose buds, and storing for later use; s2, accurately weighing 1g of rose powder and putting the rose powder into a conical flask; s3, then, according to the material-liquid ratio of 1: 40, 40% ethanol is used as a solvent, and the materials are poured into a conical flask to be mixed; and S4, finally, soaking in a constant-temperature water area, extracting for 2 hours, and finally, taking supernate for later use. According to the invention, the solid-liquid ratio of 1: 40 ensures that the rose powder is fully infiltrated by an enough solvent (40% ethanol). Under the proportion, the ethanol can be in full contact with target components (such as flavonoid compounds and the like) in the rose powder. Each 1g of rose powder is surrounded by 40ml of solvent, so that target components have more opportunities to be dissolved out of powder particles to enter the solvent, and the extraction completeness can be improved compared with the condition that a feed liquid is relatively small.

The invention relates to the technical field of plant extraction, in particular to a rose extract. The rose extract comprises at least one of monomer ellagic acid, urolithin M5 and apigenin. The preparation method comprises the following steps: uniformly mixing rose powder with the ternary synergistic solvent, carrying out ultrasonic treatment for 10-60 minutes under the ultrasonic power of 150-250 W, and then stirring for 1-5 hours at the temperature of 20-50 DEG C; centrifuging and collecting supernate to obtain the rose extract. The rose flower extract provided by the invention has relatively strong inhibition capability on human pancreatic lipase.

The application discloses a preparation method of a pollen composition with whitening and anti-wrinkle effects, a product and application thereof, and belongs to the technical field of compositions. The technical problem to be solved is to provide an active component with the double effects of whitening and anti-wrinkle, and the active component is extracted and the component is simple and stable. The technical solution is as follows: at least two or more of pine pollen, sunflower pollen, tea pollen and rose pollen are used as raw materials, the raw materials are physically crushed, then subjected to enzymolysis by using a composite cellulase, and then subjected to hot water extraction, so that whitening components and anti-wrinkle components are enriched, and the prepared pollen composition has excellent whitening effect and anti-wrinkle effect.

The invention relates to the technical field of food processing, in particular to functional rose fine dried noodles highly retaining plant active substances and a preparation method thereof.The method comprises the steps that rose powder obtained after temperature-controlled grinding is mixed with high-gluten wheat flour, gradient rolling, slitting and critical point drying are conducted, and finished fine dried noodles are obtained; in the preparation process, when a quality comprehensive evaluation value is determined and compared with an evaluation threshold value to judge that the current fine dried noodle preparation process does not meet the standard, the grinding rotating speed in the temperature control grinding process and the main drying period temperature in the critical point drying process can be correspondingly adjusted based on the real-time monitoring result of the active component content and the moisture gradient change rate; and correspondingly adjusting the roller pressure of the first calendering in the gradient calendering process based on the grinding rotating speed and the re-measured quality adjustment evaluation value after the temperature adjustment in the main drying period. The fine dried noodles prepared by the method have high plant active substance retention rate, effectively reduce the production cost and improve the quality stability of the fine dried noodles.

The invention relates to the technical field of beverages, in particular to a formula and a preparation method of a pericarpium citri reticulatae-flavored plant beverage. The rose flower beverage is prepared from the following components in percentage by mass: 35 to 85 percent of water, 0.5 to 4.5 percent of erythritol, 0.5 to 4.5 percent of double-petal red rose pollen, 3 to 8 percent of pericarpium citri reticulatae, 0.5 to 4.5 percent of double-petal red rose, 0.5 to 4.5 percent of roselle, 0.5 to 4.5 percent of lotus seed, 0.5 to 4.5 percent of Chinese yam, 0.5 to 4.5 percent of fructus lycii, 0.5 to 4.5 percent of black fructus lycii, 0.01 to 0.1 percent of mulberry, 0.02 to 3.5 percent of fructus hippophae, 0.01 to 0.25 percent of hericium erinaceus, 0.01 to 0.25 percent of ginseng, 0.01 to 0.25 percent of cordyceps militaris, 0.01 to 0.25 percent of poria cocos, 0.2 to 2.5 percent of longan and 0.2 to 2.5 percent of red date. The beverage is prepared from the following raw materials in percentage by weight: 0.01 to 0.25 percent of rhizoma polygonati, 0.01 to 0.25 percent of roxburgh rose, 0.01 to 0.25 percent of corn oligopeptide, 0.01 to 0.09 percent of astragalus mongolicus, 0.01 to 0.09 percent of lucid ganoderma, 0.5 to 4.5 percent of black chokeberry, 0.005 to 0.08 percent of perigord truffle and 0.005 to 0.08 percent of stevioside. The health-care tea has the effects of soothing liver-qi stagnation, promoting blood circulation to remove blood stasis, beautifying, tonifying spleen and stomach, preventing and resisting cancer, delaying senescence, improving immunity and the like.

The invention belongs to the technical field of diet therapy, and particularly discloses a diet therapy formula for sleep disorder, which is prepared from medicinal and edible natural food materials and functional components as raw materials according to a scientific ratio.

Through the synergistic effect of multiple components, the composition can quickly relieve nervous mood and reduce nervous excitability, so that the sleep latency is shortened, the sleep time is prolonged, the sleep quality is improved, no direct sleep effect exists, adverse reactions such as drowsiness and dizziness possibly caused by similar sedative-hypnotic drugs are avoided, and the composition is high in safety, wide in adaptability, smooth in taste and easy to accept and has a good application prospect. And a safe and effective dietary therapy solution is provided for people with sleep disorders.

This invention belongs to the field of microcapsule preparation technology, and particularly relates to a rose pollen microcapsule, its preparation method, and its application. A rose pollen microcapsule has rose pollen as the core material and soybean protein and corn starch as the wall material; wherein the mass ratio of soybean protein to corn starch is 1:1~2; and the mass ratio of the core material to the wall material is 1:3~4. This invention uses rose as the "core function," soybean protein as the "interface construction layer," and corn starch as the "glassy framework layer" to form a ternary composite structure. Through a protein-polysaccharide composite network, a biphasic microcapsule structure is formed, achieving high encapsulation efficiency, significantly improving thermal stability, antioxidant properties, and storage stability, and enabling targeted release in the small intestine.
