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, Chinese herb extract, plant P.E., Herb extract Xi'an Day Natural Inc. , https://www.dayextract.com
What is Natural Extracts?
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.
Bag silage technology
If the scale of cultivation is not large, silage materials can be added into plastic bags for silage after adding additives. This method is simple and convenient and easy to promote. Plastic bag silage referred to as bag-type silage, it only needs to cut silage materials, into plastic bags, so that the temperature is moderate, remove the bag of air, and try to compact the bag material can be. If there is no suction equipment, it must be packed tightly to minimize the amount of air in the bag. For example, if the corn stalk after the wax ripening stage is crushed to 0.6–1 cm long, as a silage material, add 3 g of formic acid per kilogram of corn stalk with a small sprayer, mix evenly, and then put it into a silage plastic bag. Compacted and sealed. The silage bag has two layers, the outer layer is a woven bag and the inner layer is a non-toxic polyethylene plastic film; the bag has a width of 1 meter and a length of 1.5 meters. The silage thus processed can be preserved for one year. In addition to the use of corn stalks, silage in plastic bags can also use grasses, sorghum stalks, bean stalks, peanut vines, sweet potato vines, and lettuce leaves. Because there is no need for civil engineering, there is less investment, and the success rate is high, and the promotion has a good future. When using a plastic bag for silage, pay attention to the following points: First, the film used to make plastic bags should not be too thin, preferably 0.9 to 1 mm. Second, the corners and bottom of the bag must be tightly sealed to ensure that they will not break when pressed on the side. Silage raw materials should be chopped and chopped. Their length should not exceed 1 to 1.5 cm. This facilitates compaction of the silage material. Thirdly, after the plastic bag is packed and compacted, it is necessary to fasten the bag as soon as possible and try to squeeze out the air when it is tied. Fourth, the moisture content of silage raw materials should be about 65%, that is, a handful of silage material should be grasped by hand. After releasing the finger, the mass will slowly spread out and the hands will not wet. Fifth, silage plastic bags should avoid livestock, poultry, animals and agricultural implements and other sharp instruments to avoid scratching plastic bags. Sixth, each time you take a silage of feed, you should tie it tightly. The silage material in the bag can be seen in the silage of the plastic bag. If the color of the silage is found to be yellow and the veins are blurred, attention must be paid to it. If the temperature in the bag rises to 60~70°C, the seal should be opened and the uncompressed area in the bag should be compacted. Then, the bag opening should be quickly tightened. Silage process, the silage temperature, will lead to a rapid decline in silage quality, poor palatability, animal husbandry refused to eat. Silages in plastic bags, such as corn stalks, are best cut and chopped and chopped. Overdrying straw can be used to adjust the humidity to achieve the optimum moisture content. Such as sweet potato vine silage, it is best to dry and then silage. Pastures and field weeds can also be stored in bags, and can also be carried out during the freezing season. Judging from the protein content, the best period of silage is before the weeds are seeded.
