A food must have the expected or proper appearance and color before it will be readily consumed (7). There are many prepared foods in which artificial flavors and colors are used whose flavor is sufticientiy bland to make color essential for flavor identification, eg, margarine. The preservation of color in natural food during processing or the development of color by processing are aspects of primary importance in food acceptance. 

Starch is often modified by hydrolysis with hydrochloric or sulfuric acid (93). The resulting product is resistant to syneresis, keeps food in suspension after cooking, and exhibits much greater free2e—thaw stabUity than unmodified starch. Modified starch is commonly used in baby food, fro2en prepared foods, pie fillings, meat products, and candy. 

There is an increasing demand for ready-prepared foods for final re-heating or cooking in microwave ovens. Applications are for retail sale of take-away meals and factory/ office and institution catering. Such foods maybe frozen and will then have a longer storage life, but will require frozen storage. 

You may have noticed Ca-EDTA on the list of ingredients of many prepared foods, ranging from beer to mayonnaise. EDTA acts as a scavenger to pick up traces of metal ions that catalyze the chemical reactions responsible for flavor deterioration, loss of color, or rancidity. Typically, Ca-EDTA is added at a level of 30 to 800 ppm. 

Processing the SCP to break up the cells (by milling or some other means), then incorporating it into prepared foods may overcome this problem. Otherwise it might be possible to use the SCP for feed. 

Prevention Follow measures to control the spread of infection. Wash hands immediately before eating or preparing food and after defecation. 

Avoid foods that contain xanthine, such as colas, coffee, chocolate and charcoal-prepared foods. 

Bound glutamates in proteins are very common in food. Human breast milk contains ten times as much as cows milk, and tomato juice contains four times as much as breast milk. However, free glutamate, as found in soy sauce or prepared foods, enters the bloodstream much faster than the glutamates bound in proteins, which are released slowly during digestion. 

Early in the century the amount of energy output in the form of food was about equal to the commercial energy input to the crop and livestock. That was before electricity, natural gas, and petroleum products were available to the farm. Now at least 10 kcal of commercial energy is used for each kcal of food energy produced. This change has occurred as a result of mechanization, irrigation, and consumer demand for low fat foods and for precooked and prepared foods.

Chapter 10 is devoted to the preparation and purification of hydrophilic vitamins (C, Bj, Bj, Bg, B[2, nicotinic acid and nicotinamide, pantothenic acid, biotin, and folic acid) in pharmaceutical preparations, food products, and biological samples.

Enzymes from these organisms find numerous applications beyond PCR. Certain ones can modify plant fibers or break down proteins or fats. Heat-stable enzymes with these digestive properties are very attractive to the food processing industry. Properly controlled, their action can make prepared foods more palatable, and they can be employed where ordinary enzymes fail. In food processing, all operations must be carried out under sterile conditions. Frequently, the easiest way to maintain sterility is to keep the... 

Sugar is a common ingredient in prepared foods. When sugar remains on your teeth, bacteria in your mouth convert it into an acid. The principal constituent of tooth enamel is a mineral called hydroxyapatite, Caio(P04)6(OH)2. Hydroxyapatite reacts with acids to form solvated ions and water. (Solvated ions are ions surrounded by solvent particles.) Eventually, a cavity forms in the enamel. 

The plants and animals we have chosen to use as foods naturally contain, as we have already noted, thousands of chemicals that have no nutritional role, and when we eat to acquire the nutritionally essential chemicals we are automatically exposed to this huge, mostly organic, chemical reservoir. Of course, human beings have always manipulated foods to preserve them or to make them more palatable. Processes of food preservation, such as smoking, the numerous ways we have to cook and otherwise prepare food for consumption, and the age-old methods of fermentation used to make bread, alcoholic beverages, cheeses and other foods, cause many complex chemical changes to take place, and so result in the introduction of uncounted numbers of compounds that are not present in the raw agricultural products. 

With the exception of starch, many biopolymers cannot provide nutrition for humans and other omnivorous animals. In human foods biopolymers are used as additives that can improve texture, viscosity, fiber content, and other properties of prepared foods, without providing direct nutritional values. Examples of such utilization are the addition of pectins, agar, and other gums to foods to achieve thickening and gelling effects. Another example of potential large-scale utilization of cell wall biopolymers is the dramatic improvement in the texture and rising of breads prepared from com and other starches by the addition of xylans (78). 

In industrialized countries, exposure to potential infectious risks has increased because of changing sociologic patterns (e.g., more frequent consumption of commercially prepared food and expanded childcare services). Environmental sanitation and public health services, despite room for improvement, are generally good. In addition, choices of hygienic skin care products have never been more numerous, and the public has increasing access to health- and product-related information. 

Since before recorded history, we have been using chemical processes to prepare food, ferment grain and grapes for beverages, and refrne ores into utensils and weapons. Our ancestors used mostly batch processes because scaleup was not an issue when one just wanted to make products for personal consumption.
