Animal food additives

Vitamin C, or ascorbic acid, is surely the best known of all vitamins. It was the first vitamin to be discovered (1928), the first to be structurally characterized (1933), and the first to be synthesized in the laboratory (1933). Over 200 million pounds of vitamin C are now synthesized worldwide each year, more than the total amount of all other vitamins combined. In addition to its use as a vitamin supplement, vitamin C is used as a food preservative, a "flour improver" in bakeries, and. an animal food additive.

The high moisture and organic matter contents of this residue mrns it into a low-value commercial product. Therefore, several attempts have been made to valorize the wet pomace, although with relatively low economical success, including its use as natural fertilizer, as a combustible, and animal food additive [17, 23]. More valuable are their phenolic constituents, which represent 98% of the total phenols in the olive fruit [24-28]. The total amount of phenolic compounds that can be extracted from the two-phases olive pomace is approximately 150 mg g (as expressed in oleuropein equivalents) of the dried, defatted and dehulled two-phases olive pomace [16]. The methanolic extract obtained from this residue has a complex... 

Use B. is used especially in topical application (wound infections, bums, skin grafts). On or administration B. is practically not resorbed. B. is widely used in animal breeding as animal food additive. 

Phosphorylation of corn starches reduces retrogradation and improves other properties for food applications (Chapter 12.4). Corn starch phosphates will improve the water-retention properties of soils and they can be used as animal food additives. 

Total extraction has the target to obtain the highest possible yield of soluble substances, whereas a single separation results in a so-called total extract, hut multiple separations allow fractioned products. Typical examples are the extraction of spices, herbs, and hops. One likes to obtain the exhaustive lead substances as a-acids from hops or piperine from pepper, or gingeroles from ginger, or carotinoids from paprika and so on on the one hand and the corresponding aromas on the other. The extraction residue from the extractor is mostly without any value, hut can sometimes be used as fertilizer basis or animal food addition.
