Nonnutrient Additives. Nonnutritional dietary additives provide antioxidants to preserve freshness, flavor enhancers to stimulate food selection, color to meet the owner s expectations, pellet biaders to minimi2e fine particles, mycostats to minimi2e mold growth, and iagredient-flow enhancers. Pet foods do not iaclude coccidiostats, antibiotics, added hormonal materials, and fly-larval iasecticides used ia other animal feeds. 

As energy costs have escalated in recent years, the use of high moisture food by-products in commercial animal feeds has also escalated, particularly in beef cattie and dairy rations, as a means of reducing production costs. Because of the broad activity spectmm, sorbates are extremely effective in the preservation of wet by-products, eg, brewers and distillers grains, beet pulp, citms pulp, and condensed whey (139). 

The commercial uses of arsenic compounds in 1988, measured in terms of elemental arsenic, are wood (qv) preservatives, 69% agricultural products (herbicides (qv) and desiccants (qv)), 23% glass (qv), 4% nonferrous alloys and electronics, 2% and animal feed additives and pharmaceuticals (qv), 2% (see Feeds AND feed additives). Chromated copper arsenate (CCA) [11125-95-4] is the most widely used arsenic-based wood preservative. The Environmental Protection Agency has, however, restricted the use of arsenical wood preservatives to certified appHcators. 

Zinc sulfate (ZnSO ZH O) is also known as zinc vitriol or white copper. In addition to being used to make rayon, zinc sulfate is used as a wood preservative, a dietary supplement, an animal feed, and as a mordant to prevent dyes from running in printed textiles. It can also be used to stanch bleeding. 

Phosphoric acid is used as an intermediate in the production of animal feed supplements, water treatment chemicals, metal surface treatments, etching agent, and personal care products such as toothpaste. It is used as a catalyst in the petroleum and polymer industry. Phosphoric acid is used in food as a preservative, an acidulant, and flavor enhancer it acidifies carbonated drinks such as Coca Cola and Pepsi, giving them a tangy flavor. Phosphoric acid is used as a rust remover and metal cleaner. Naval Jelly is approximately 25% phosphoric acid. Other uses for phosphoric acid include opacity control in glass production, textile dyeing, rubber latex coagulation, and dental cements. 

Oxidation of the lipid structure in foods containing oils and fats produces carbonyl compounds which are responsible for the flavor and odor associated with rancidity (B-81MI11508) the use of a suitable antioxidant can delay this process. Several heterocyclic compounds are among the antioxidants suitable for use in food ascorbic acid (69) and certain of its derivatives and erythorbic acid. The quinoline derivative (70) is mainly used as an antioxidant in animal feed, but it can also be used to preserve the color of paprika, chili powder and ground chili. 

There are marry sources of variability related to the sampling, handling, transfer, and preservation of samples. The preparation, sampling, and analysis of animal feeds deserve special attention. 

Acceptance of DDG and DDGS products as animal feed supplements is limited by the variable "quality" of DDG and DDGS among ethanol plants and the relatively low crude protein content (4). This variability is caused by differing amounts of residual starch and crude protein in DG products. Crude protein content depends in part on preserving protein during the drying step.

The major use of arsenic is for agricultural pesticides, wood preservatives and animal feed additives. 

Estimated end-use distribution of arsenic in the United States was 70% (16,000 tons as elemental arsenic) in industrial chemicals (mainly as wood preservatives), 22% (5200 tons) in agricultural chemicals (mainly as herbicides and desiccants), 4% (900 tons) in glass manufacture, 3% (700 tons) in nonferrous alloys and 1% (300 tons) for other purposes (animal feed additives, pharmaceuticals etc.) in 1989. Estimated end-use of arsenic in Japan was 35% (230 tons) for refining of zinc, 34% (220 tons) for glass manufacture, 15% (100tons) for electronics as ultrapure arsenic metal and 15% (lOOtons) for wood preservatives and agricultural chemicals in 1988. 

Use Rayon manufacture, dietary supplement, animal feeds, mordant, wood preservative, analytical reagent.
