Most aflatoxins are chemically stable, so they tend to survive storage and processing, even when cooked at quite high temperatures such as those reached during baking bread or breakfast cereal production. This makes it important to avoid the conditions that lead to aflatoxin formation, which is not always possible and not always achieved in practice. Aflatoxins are notoriously difficult to remove and the best method of control is prevention [24]. 

Other soluble fiber-containing products have been shown to lower blood cholesterol. Recent extensive studies on psyllium (Plantago ovata) presented both as a pharmaceutical preparation and as a food product (a ready to eat breakfast cereal) have shown blood cholesterol-lowering properties where the dose-effect relationship is such that a useful additional therapeutically meaningful lipid-lowering effect can be achieved by prescribing a daily portion of psyllium-fortified breakfast cereal. Products of this type are now marketed in the US and Australia, and the US FDA has now allowed a food specific health claim for psyllium. 

Semolina is the coarsely ground endosperm of dumm wheat. High in protein, it is used by U.S. and ItaHan manufacturers for high quaHty pasta products such as macaroni and spaghetti. In Africa and Latin America it is also used for a dish called couscous. Dumm flour, a by-product in the production of semolina, is used to make commercial American noodles. Farina is the coarsely ground endosperm of hard wheats. It is the prime ingredient in many American breakfast cereals. It is also used by manufacturers for inexpensive pasta. 

Cereal Products. Breakfast cereals are susceptible to moisture absorption and require good water-vapor- and fat-barrier packagiag that retains dehcate flavors. Breakfast cereals are packaged in polyolefin coextmsion films in the form of pouches or bags within paperboard carton outer sheUs. 

Used in baked goods (breads, cakes, cookies, crackers, doughnuts), pasta products, emulsified and coarsely ground meat products, meat analogues, breakfast cereals, dietary foods, infant foods, confections, milk replacers, and pet foods. 

The ABC cereal company is developing a new type of breakfast cereal to compete with a rival product that they call Brand X. You are asked to compare the energy content of the two cereals to see if the new ABC product is lower in calories so you burn 1.00-g samples of the cereals in oxygen in a calorimeter with a heat capacity of 600. J-(°C). When the Brand X cereal sample burned, the temperature rose from 300.2 K to 309.0 K. When the ABC cereal sample burned, the temperature rose from 299.0 K to 307.5 K. (a) What is the heat output of each sample (b) One serving of each cereal is 30.0 g. How would you label the packages of the two cereals to indicate the fuel value per 30.0-g serving in joules in nutritional Calories (kilocalories) ... 

Often the need or desire can be satisfied by a substance that is presently on the market, but it is projected that a new product will either do a betteijob, cost less, or require less time and effort. The toothpastes produced before 1960 did a respectable job of cleaning teeth, but the addition of fluoride made them better cavity preventa-tives, and those toothpastes that added fluorides became the best sellers. Orange juice could be shipped in its natural form to northern markets, but frozen concentrated orange juice occupies one-fourth the volume and costs less to the consumer. TV dinners and ready-to-eat breakfast cereals cost more than the same foods in their natural state, but they reduce the time spent in the kitchen. All of these items resulted from research followed by design. 

Products where this is the sole expansion system are extruded products. This sort of cooking is used for the production of breakfast cereals, savoury snacks and some crisp breads. Of these, only the crisp breads are really within the scope of this book. 

Taco Bell and other food companies recalled 300 products (150 brands of corn chips, taco shells, corn dogs, corn bread, breakfast cereals and polenta), but decided to continue selling taco shells obtained from the same supplier. 

The only full-fat oilseed flour with significant domestic sales is soy. It has been used in bakery products, breakfast cereals, canned baby foods, canned infant formulas for lactose-intolerant babies, and adult dietary beverages (24). 

Soy flours and concentrates are used in compounded breakfast cereals, primarily for improving total protein content and PER. In the absence of dry nonfat milk solids, glucose is often included in bakery products formulations to impart a toasted brown color. Most... 

E 420, E 421, E 953, E 965, E 966 and E 967 are polyhydric alcohols and they are allowed to quantum satis in certain foods that are energy-reduced or with no added sugar, including certain dessert products, breakfast cereals, edible ices, jams and marmalades, certain confectionery products, line bakery wares and sandwich spreads in chewing gum with no added sugar and in sauces, mustard, products for particular nutritional uses and solid supplements/dietary integrators. 

Vitamins occur naturally in many foods and raw materials. However the natural contents are often supplemented in many food products to ensure an adequate intake, for example in infant formulae, breakfast cereals and clinical nutrition products. Vitamins are usually added as nutrients and thus not covered in this chapter but may also be added as food colours (riboflavin, carotenes). The reader should refer to the following references for recent developments in... 

Plastic materials are the main components of food packages used for dairy products, baked goods, breads, beverages, breakfast cereals, confectionery, pasta, and other miscellaneous food products (Table 14.1).

The fat-soluble vitamins comprise vitamins A, D, E, and K, whose biological activities are attributed to a number of structurally related compounds known as vitamers. Also included are those carotenoids that are precursors of vitamin A. Recommended dietary allowances (RDAs) based on human epidemiological and experimental animal studies have been published in the United States for vitamins A, D, E, and K (1). Other countries and international bodies have compiled similar recommendations. In the United States and Canada, fluid milk is supplemented by law with vitamin D to a level of 400 international units per quart (10 /zg/0.95 L) to meet the RDA of 10 p%. Other commodities, such as margarine, milk products, ready-to-eat breakfast cereals, and dietetic foods, are commonly supplemented with vitamins A, D, and E. Except for infant formulas, vitamin K is not added to foods. The addition of vitamins to a particular processed food is intended to provide a specific proportion of the RDA. 

Schneiderman et al. (90) extracted retinyl palmitate from commercial breakfast cereals using supercritical C02 and determined the vitamin by means of reversed-phase HPLC and electrochemical detection. Chromatograms of an unfortified wheat sample and a fortified bran-based cereal product are shown in Fig. 10. 

Oats are used in breakfast cereals and baked goods. Oat bran is high in soluble fiber, which can help lower blood cholesterol levels, thus possibly reducing the risk of heart attacks. It also helps the body utilize insulin more efficiently, an important asset in controlling diabetes. Products made with oats contain little or no gluten and can usually be tolerated by people with celiac disease. 

There are some important cyclic compounds such as the lactone 75, succinic anhydride 76, furan 77, and many substituted furans, particularly furfuraldehyde 78, a by-product of breakfast cereal manufacture, and its reduction product 79 and maleic anhydride 80.
