Horn meals

Mechanical foam A substance introduced into the water line by various means at a 6% concentration. Air is then introduced to yield foam consisting generally of 90 volumes air, 9.4 volumes water, and 0.6 volumes foam hquid. It uses hydrolyzed soybean, fish scales, hoof and horn meal, and peanut or com protein as a base. 

A European Council decision of 4 December 2000, which remains in force but under review, defined processed animal proteins as meat and bone meal, meat meal, bone meal, blood meal, dried plasma and other blood products, hydrolysed proteins, hoof meal, horn meal, poultry offal meal, dry greaves, fishmeal, dicalcium phosphate and gelatin. It directs that member states shall prohibit the use of processed animal proteins as food for farmed animals that are kept, fattened or bred for the production of food for human beings. Rshmeal may be given to non-ruminants, and the prohibition does not apply to milk and milk products.

Protein foam concentrates are produced by hydrolysis products of proteinaceous matter, such as hoof and horn meal, chicken feathers, or fish meal. Fluoro-protein concentrates are protein foam concentrates with fluorinated surfactants added. The fluorinated surfactants add to the cost of the protein-based foam agents but enhance fire-extinguishing efficiency by repelling hydrocarbon fuel when the foam is covered with fuel. Fluoroprotein foam introduced to a base of a burning fuel tank rises through the fuel and extinguishes the fire. The low surface tension allows fluoroprotein foam to move rapidly over a hydrocarbon fuel surface [133-138]. 

Meat and Bone Meal is the rendered product from mammal tissues, including bone, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach, and rumen contents, except in such amounts as may occur unavoidably in good processing practices. It shall contain a minimum of 4.0% phosphorous (P), and the calcium (Ca) level shall not be more than 2.2 times the actual phosphorous (P) level.

Bone is found occasionally on archaeological sites when conditions of preservation permit. Bone most often occurs at the inedible waste of meals or the remains of human burial. In addition, bone and other skeletal tissue from animals (teeth, antler, shell, horn) was often used to make certain kinds of tools and equipment. Archaeozoologists are trained to identify the genus and species of animal from small pieces of bone, as well as to determine the age and sex of the animals, how bone was fragmented, and how many individual animals are represented in a set of bones. Bone can answer questions about whether animals were scavenged, hunted, or herded, their age and sex, about how animals were butchered, about how important meat was to the diet, when animals died, and the process of domestication. 

Ford researchers found more practical uses for the soybean. They mixed the oil into enamel car paint, and they molded soybean meal to make horn buttons, gearshift knobs, door handles, and even acceleration pedals. Robert Boyer, Ford s main soy researcher, made plastic sheets of soybeans that could replace steel. He installed a soy trunk lid on one of Henry s... 

Dried blood, ground hoof and horn and meat and bone meal are also used the plant food content is variable. 

The two schemes usually followed in the isolation of peanut proteins from oil-free meals are (1) the salting-in and salting-out method of Jones and Horn (122) for the preparation of arachin and conarachin and (2) extraction of the proteins with dilute aqueous sodium hydroxide at pH 7.5 and precipitation of the proteins with gaseous sulfur dioxide at pH 4.5 (7,10,36,47-50,54,127,139-141,163,166). The method of Jones and Horn (122) previously outlined is used in preparing purified fractions of peanut protein for physical chemical investigations. 

Other protein materials utilized in the production of formaldeh> de-modified resins and plastics include dried blood, yeast, leather waste, and ege-table proteins such as gluten, zein, ground-nut protein, cottonseed meal, and keratin from hoofs, horn, hah, and feathers.
