1. Prepare the paste: Start with 50 kilograms of sweet potato starch, mix it with 60 kilograms of water and 150 grams of white peony root. Stir everything thoroughly until you get a smooth, thin paste. This step is crucial to ensure the texture is consistent and suitable for the next stage.
2. Spinning process: Use a flat-bottomed hot plate for this step. Place the hot plate inside a pot filled with water. Once the paste is ready, carefully pour it onto the hot plate. Immediately start rotating the plate to spread the mixture evenly across its surface. As the paste begins to thicken due to heat, quickly lift the plate and submerge it into boiling water to complete the cooking process.
3. Cooling and preparation: After the pink skin (gouache) is cooked, transfer it into cold water for a short period to cool down. Then, remove it and prepare it for use. Gouache can be finely chopped and used in various dishes or eaten on its own with simple seasonings like onions, oil, salt, and monosodium glutamate. If you plan to sell the dried version, the gouache can be bleached in a pulp solution, rinsed with fresh water, and then dried for storage and sale.
This traditional method not only preserves the unique texture and flavor of the sweet potato starch but also allows for versatile usage in both fresh and dried forms. It's a time-honored technique that has been passed down through generations, offering a delicious and nutritious option for many different meals.
What is Natural Extracts?
Natural extracts are biologically active compounds or mixtures extracted from various plants and animals or microorganisms in nature. These extracts contain a wealth of chemicals, Such as alkaloids, flavonoids, saponins, polysaccharides, volatile oils, collagen, proteins, peptides, enzymes, antibodies, antibiotics, Amino Acids, nucleic acids, enzymes, monosaccharides, oligosaccharides, polysaccharides, glycoproteins, resins, colloids, lignin, vitamins, fats, oils, waxes, alkaloids, volatile oils, flavonoids, glycosides, phenylpropanoids, organic acids, phenols, quinones, steroids And antibiotics, etc.
Natural extracts have received attention in several fields due to their wide range of sources and potential multiple uses. They can be used in the pharmaceutical industry as ingredients in medicines or health supplements; In the cosmetic industry, as a functional or active ingredient to improve skin health; In the food industry, as an additive or flavoring agent to increase the nutritional value and taste of food; In addition, they have different applications in the fields of agriculture, environmental protection and scientific research.
Extraction methods include solvent extraction method, ultrasonic extraction method, microwave extraction method, enzyme extraction method, supercritical fluid extraction method and microwave assisted extraction method, etc. The choice of which method usually depends on the nature of the substance to be extracted and the target requirements of the final product. With the development of technology, the extraction process is continuously optimized to improve extraction efficiency, reduce environmental impact and maintain the biological activity of the extract.
