Potted yellow mealworms can be used with old washbasins and other feeding equipment. These utensils are required to have no holes and smooth inner walls. If the inner wall is not smooth, stick a tape around it to form a smooth belt to prevent insects from fleeing. In addition, a 60-mesh sieve is required. After the insect species are obtained, they are first carefully screened to select a large individual with strong vigor and bright color. The ordinary washbasin can raise 0.3 to 0.6 kg of larvae. Put the feed in the pot, such as wheat bran, corn flour, etc., and then put into the larval insect species, the amount of feed is 10% to 20% of the weight of the insect. After 3 to 5 days, the insects eat the feed, and the insect feces is sieved out with a 60 mesh sieve. Continue to feed the feed, and feed some vegetables and melons with high water content. When the larvae larvae, they should be picked out and stored in time. After 8 to 15 days, eclosion became adult. Spread a piece of paper on the bottom of the pot, then lay a layer of fine feed about 1 cm thick on the paper and put the feathered adult on the feed. At a temperature of 25°C, adult mating began about 6 days after emergence. Tenebrio are social insects, mating and spawning must have a population density of 1500-3000 per square meter. During the oviposition period of adults, better concentrate feeds should be fed, in addition to mixed feed plus multivitamins, and appropriate amounts of feed with high moisture content. When the adult spawns, the ovipositor is extended to the feed and the eggs are laid on the paper. After 3 to 5 days, the eggs are stuck on the egg paper and the new egg paper should be replaced. The eggs were removed and placed in a pot on the same date until they hatched. When the temperature is 24°C to 34°C, it can hatch after 6 to 9 days. The newly hatched larvae are very soft, so try not to touch them with your hands so as not to injure them. The newly hatched larvae are kept together and the larvae go through 15 to 20 days. After the feed in the pot is basically consumed, the insect excrement can be screened for the first time. Sieves and feces use a 60-mesh sieve, after which the insect feces is sieved once every 3 to 5 days, and the feed is fed once. The input amount of feed can be sorted by larvae for 3 to 5 days. Feeding leaves or melon peels should be on the day before the worm screening. The amount of larvae fed can be given in one night, or the worms can be screened out before feeding the leaves or melons. As soon as the next day, the uneaten leaves and melons are picked.
Natural Extracts
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.
