1. Bran In the bran, it is often found that talcum powder, rice bran, etc. are mixed, and the amount of the blend is generally 8 to 10%. Insert the hand into a pile of bran and then withdraw. If there is a white powder on the finger, and it is not easy to shake off, it means that talcum powder is added; if it is easy to shake off, it is residual flour; then grab a handful of bran and push it hard. If the bran is in a group, then it is pure bran; when the boiled hand has a feeling of rising, it is mixed with a rice bran; if the bran has a slippery feeling in the palm of the hand, it means that it is mixed with talcum powder. 2. Soybean meal (cake) Soybean meal (cake) is often mixed with sand, broken corn, or 5 to 10% of stone powder, and the protein content of the bean cake is reduced to 30%. Water immersion method: 25 grams of pods (cakes) to be inspected are soaked in a glass filled with 250 ml of water for 2 to 3 hours, and then the pods (cakes) and sediment are read by gently stirring with a wooden stick. The upper layer is cake pancake and the lower layer is sediment. Identification method of iodine: Take a few pods (cakes) on a clean disk, spread out and spread a few drops of iodine on it. After 1 minute, if any of the substances turn blue-black, it means that there is corn, Bran, rice husks and so on. Raw and cooked soybean meal inspection method: commonly used cooked bean cake as raw materials, rather than raw soybean cake, because raw soybean cake contains anti-trypsin, saponin and other substances, affecting the palatability and digestibility of livestock and poultry. The method is to take 0.1 g of urea into a 250 ml conical flask, add 0.1 g of measured soybean meal, add distilled water to 100 ml, and add the stopper to warm water at 45° C. for 1 hour. A piece of red litmus paper is immersed in this solution. If the litmus paper turns blue, it indicates that the pod is raw. If the test paper does not change color, the pod will be cooked. 3. Fish meal Fish meal mixed with cottonseed meal, rapeseed meal, urea, sand and other debris, its protein content will drop to 40%. Sensory detection method: The standard fish meal particles have the same size. A large number of loose fish muscle fibers and a small amount of fish bones, fish scales, and fish eyes can be seen. The color is light yellow, yellow brown or yellow brown. There is a sense of looseness in the hand, no agglomeration, and no hair. Sticky, fish smell, no smell; adulterated fish meal can be seen in particles, shape, color impurities, rare or no fish fiber and bone, thorns, eyeballs, etc., powdery and fine particles, easy to agglomerate was small Cluster, hands clumped, sticky, light fish, smelly. Odor detection method: Take 20 grams of sample into a flask, add 10 grams of soybean cake and the appropriate amount of water, add 15 to 20 minutes after plugging, remove the lid, if you can smell the ammonia odor, indicating that doped with urea. Water immersion method: Take a small amount of sample into a test tube or glass, add 10 times of water, fully shake and stand. If there is gravel or other minerals, it will sink to the bottom of test tube or glass, if there is cotton cake, Feather powder, bran, etc. will surface; true fishmeal does not have this phenomenon. 4. Bone meal Good bone meal contains 23 to 26% calcium and 12 to 14% phosphorus. Adulterated bone powder is often poor in phosphorus, causing both feet (legs) to become stung; undebonded bone meal is prone to spoilage and causes poisoning in livestock and poultry. Common adulterants include lime powder, shell powder, and fine sand. Intuitive visual method: pure bone powder is grayish white powder or granular, some particles are honeycomb, with inherent odor; doped bone meal only a little honeycomb particles; false bone meal without honeycomb particles, bone powder, shell powder White. Dilute hydrochloric acid dissolution method: The bone powder is poured into dilute hydrochloric acid solution. If it is a pure bone powder, it will give off a short “sand†sound. The surface of the bone powder particle will not generate bubbles, and finally it will all dissolve into turbidity. The degummed bone powder will float on the surface of hydrochloric acid solution. There is a very small amount of organic matter; there are many floating surfaces on the surface of bone powder and bone powder, and there are no chemical phenomena above. Burning method: Take a small amount of bone meal in a test tube, place it on fire and roast it. The true bone powder produces steam, and then produces the pungent smell of burning hair. The adulterated bone powder produces less steam and odor, and the bone meal powder has no steam. And odor; undegummed metamorphic bone meal has an odor. 5. Shell powder Fake shuck shell powder was surface or crumb-like, calcium content was 28%; good shell powder should contain more than 70% sorghum grain shell size, less than 30% of the broken surface. It is best to use unprocessed and crushed large shells, own processing, after the crushed calcium containing more than 36%.
