After animals are slaughtered, meat is what the most people need, and the demand of meat and its big economic benefits are the focus of social concern. However, the animal bones are treated as tailpieces with no use value, so they are not getting good utilization, which causes huge waste of available resources, and is not good for creating economic profits and protecting the environment. After bone processing by bone process equipment, such as bone crushing machine and bone paste grinding machine, animal bones can become valuable materials.
What Products We Can Get by Processing Animal Bones
Animal bone products has a wide variety that can be divided into two broad categories: the extractive products and the all-bone-using products.
---All-bone-using Animal Bone Products
The all-bone-using product is to grind the fresh animal bones into particles with different sizes, and then process the particle into special products based on manufacturing requirements. And the major productions includes bone paste, and bone powder that can be an alternative of meats, or nutrition additives to be added into meat-based products to improve their flavors.
1. Bone Paste
Processing animal bones into bone paste is an ideal and widely-adopted method to take advantage of animal bones that are preferred to be discarded in the first place. The research of using fresh animal bones to make edible bone paste dates from the 1970s, which is firstly succeeds in Denmark, Sweden, etc. developed countries, then has a rapid spread in Japan, America, etc., and Japan especially has great achievement.
The bone paste is produced by ultra-fine bone grinding machine, grinding the animal bone into particles sized by 200-400 mesh. The bone paste tastes as good as meat, but with more nutrients, like the calcium, protein, fat, vitamin, collagen, chondroitin and micro-elements. Also the bone paste consists of the phospholipid and phosphoprotein for human brain need; the chondroitin, ossein for supplementing body energy and delaying senescence.
The bone paste can be employed as raw material to make bone paste cookies, high-calcium rice noodles, meatballs, meat stuffing, sausage, rice dumplings and bone paste floss.

2. Bone Powder
The bone powder is high in kalium, calcium, phosphorus, iron, protein, micro-element, amino acid, etc., and the ratio of calcium and phosphorus is 2:1 which is close to the ratio for human body needs, so bone powder is an ideal product for calcium supplement. The edible superfine bone powder can be used as food nutritive fortifier; the crude bone powder can be used as additive for animal feed to help animal growing, or can be used as efficient organic fertilizer to improve acid soil and promote crop growth.
The superfine bone powder is easy to be absorbed by human body to make better use of its nutrition. The superfine bone powder is preferred to use for fast food, snack food, puffed food, catering food, health food and seasoning, etc.
Crude bone powder production process
Fresh animal bones---bones degreasing---bones drying---bones crushing---finished bone powder
Edible superfine bone powder production process
Fresh animal bones---bones cleaning---bones dehydrating---bones crushing---crude bones grinding---fine bones grinding---bones degreasing---superfine bones grinding---cooling and packing---finished bone powder
---Animal Bones Extractive Products
The animal bones extractive product is to use hydrolyzing, separating, etc. process technology to separate and extract the effective components from animal bones, which involves bone oil, bone glue, gelatin, hydrolysis animal protein (HAP) and calcium and phosphorus preparations, etc. And these extractive products are widely employed in medicine and food industries.
