Food processing, definition

Since food processing and handling bears Uttle relationship to the subject of this book, further discussion is definitely out of order. It only needs to be emphasized again that biochemists and nutritionists have made such rapid advancements in recent years that, if a food deficiency were detected in any processed food, the manufacturing process would quickly be modified to produce a satisfactory product.

These two examples illustrate that different food additive definitions tend to be very similar because a general consensus has been reached among the majority of countries as to what an additive is. It should also be pointed out that a special statute is normally reserved for dietetic products, nutritive substances added to food products (e.g., vitamins, amino acids, minerals, etc.), technological processing aids, and aromas. 

Nutraceuticals are nonspecific biological therapies used to promote wellness, prevent malignant processes, and control symptoms. It is a broad umbrella term used to describe any product derived from food soiuces that provides extra health benefits in addition to the basic nutritional value foimd in foods. The definition of nutraceuticals and related products often depends on the soiuce. Phytochemicals and antioxidants are two specific types of nutraceuticals. It has been proved that phytochemicals found in foods may help to provide protection from diseases such as cancer, diabetes, heart disease, and hypertension, for example, carotenoids found in carrots. Antioxidants may be helpful in avoiding chronic diseases, by preventing oxidative damage in body [8]. There are multiple different types of products that come imder the category of nutraceuticals ... 

For the classification of ascorbic acid status as deficient, sufficient, or optimal, a relatively clear range of reference values exists. Table V shows the reference range for the definition of ascorbic acid status. Data derived from dietary records on the intake of ascorbic acid have to be handled carefully, since the concentrations in food show a wide range depending on several sources of variation (genotype, seasonal, food processing, etc.). Empirically estimated intake data are not always satisfactory... 

In foods processed for safety, such as pasteurised milk, cooked meat products, dried infant formulae and similar products, Enterobacteriaceae are the most appropriate indicator organisms They are more accurately defined in the taxonomic sense and as a rule are more numerous than the coli-aerogenes group, which was and still is in use for the same purpose. Their more precise taxonomic definition leads to considerably better reproducibility than when the coli-aerogenes group as presently ill-defined " " is used . This is a tremendous advantage in the case of foods entering international trade. 

Historically, dietary fiber referred to iasoluble plant cell wall material, primarily polysaccharides, not digested by the endogenous enzymes of the human digestive tract. This definition has been extended to iaclude other nondigestible polysaccharides, from plants and other sources, that are iacorporated iato processed foods. Cellulose [9004-34-6] (qv) is fibrous however, lignin [9005-53-2] (qv) and many other polysaccharides ia food do not have fiberlike stmctures (see also Carbohydrates). 

The new continuous casting processes, in contrast to ingot cast products, provide tin mill products which are exceptionally clean and formable. The deoxidizing processes required for continuous casting involve either aluminum or silicon killing, which adds aluminum or silicon to the steel. Experience with type D steels indicates that the added aluminum will not cause a corrosion problem. Laubscher and Weyandt (18) have shown that the silicon found in silicon killed, continuous cast, heavily coated ETP will not adversely affect the corrosion performance of plain cans packed with mildly acid food products in which tin usually protects steel. The data on enameled cans is not definitive. Additional published data are required to determine whether or not silicon actually reduces the performance of enameled cans made from enameled, heavily coated, silicon killed, continuous cast ETP.
