Nutritional composition production

Important intrinsic quality criteria currently determining the market potential of new apple cultivars are related to the sensory quality such as fruit firmness (crispness) and the sugar and acidity contents. On the other hand, the nutritional composition (e.g. the vitamin or antioxidant contents) is currently not used as a criterion in the choice of cultivars, neither in conventional nor in organic fruit production. The difference in the content of such components between fruit species is in most cases more relevant than between cultivars of the same species (e.g. vitamin C content of oranges versus apples). 

Unstabilized bran and polish have been used almost exclusively for animal feed, due to the bitter flavor that develops from the lipolytic action of enzymes on the oil found in them. However, development of a thermal process that inactivates the lipases has resulted in a stabilized rice bran product that is suitable for the food industry. The impressive nutritional qualities of the oil, fiber, carbohydrate and proteins of rice bran have made it a valuable food material. Removal of fiber from the bran by physical K,J7or enzymic1819 processes produces a milk-like product having desirable nutritional and functional properties. The nutritional composition of the rice bran milk product described by California Natural Products has been shown to match the nutritional requirements of an infant formula. Originally, the anti-nutritional factor of the residual phytates was of concern. However, as of 2005, phytase enzymes are suitable for use to break down these phytates. 

This chapter reviews the source and composition of rice bran oil, its nutritional characteristics, production, and rehning of the oil and its applications. 

The overall objective of this chapter is to review the past, present, and future role of the sweet potato (Ipomoea batatas [L.] Lam) in human nutrition. Specifically, the chapter describes the role of the sweet potato in human diets outlines the biochemical and nutritional composition of the sweet potato with emphasis on its (3-carotene and anthocyanin contents highlights sweet potato utilization, and its potential as value-added products in human food systems and demonstrates the potential of the sweet potato in the African context. Early records have indicated that the sweet potato is a staple food source for many indigenous populations in Central and South Americas, Ryukyu Island, Africa, the Caribbean, the Maori people, Hawaiians, and Papua New Guineans. Protein contents of sweet potato leaves and roots range from 4.0% to 27.0% and 1.0% to 9.0%, respectively. The sweet potato could be considered as an excellent novel source of natural health-promoting compounds, such as p-carotene and anthocyanins, for the functional food market. 

The detailed overview on the nutritional composition and health promoting components of hazelnut provided in this chapter summarizes the existing knowledge and appreciation for the use of hazelnut and its products in a variety of food and specialty products. Besides nutritional value and health aspects, the presence of taste- and aroma-active components contribute to the sensory characteristics of products. Thus, better taste and aroma/flavor of hazelnut may increase the consumption of this nutritionally important nut, as discussed in this chapter. In addition, characteristics of raw (natural) hazelnut as well as its health promotion and disease prevention aspects are given in detail. Aroma-active components of roasted hazelnut are also discussed.

NUTRITIONAL VALUE OF COCONUTS. The nutri tional value varies according to the coconut product. The nutritive composition of some coconut products is given in Food Composition Table F-21.

Inulin is widely applied in food products. It can be used for either its nutritional advantages or its technological properties, though it is often applied to offer a double benefit an improved organoleptic quality and a better-balanced nutritional composition. 

Cereals constitute the main source of energy for poultry and swine. The most popular feed grains are maize, sorghum, oats, and barley. These grains have an excellent palatability, especially oats. Tables 18.9 and 18.10 summarize nutrition composition and energy values for poultry and different livestock animals of the most common feed cereal gains and their by-products. 

Most by-products obtained from the various milling industries (Chapters 7,8, and 9), the brewing industry, and bioreflneries (see Chapter 14) are commonly channeled to the feed industries. These by-products are divided into fiber, energy, and protein-rich feedstuffs. Tables 18.9 and 18.10 smnmarize the nutritional composition and energy values of the most common cereal by-products for different animal species. 

The sacroplasmic proteins myoglobin and hemoglobin are responsible for much of the color in meat. Species vary tremendously in the amount of sacroplasmic proteins within skeletal muscle with catde, sheep, pigs, and poultry Hsted in declining order of sarcoplasmic protein content. Fat is also an important component of meat products. The amount of fat in a portion of meat varies depending on the species, anatomy, and state of nutrition of the animal. The properties of processed meat products are greatiy dependent on the properties of the fat included. Certain species, such as sheep, have a relatively higher proportion of saturated fat, whereas other species, such as poultry, have a relatively lower proportion of saturated fat. It is well known that the characteristic davors of meat from different species are in part determined by their fat composition. 

Proteins and Meals. Nutritional properties of the oilseed protein meals and their derived products are deterrnined by the amino acid compositions, content of biologically active proteins, and various nonprotein constituents found in the defatted meals. Phytic acid (3), present as salts in all four meals, is beheved to interfere with dietary absorption of minerals such as 2inc, calcium, and iron (67) (see Food toxicants, naturally occurring Mineral nutrients). ... 

Nutritional Requirements. The nutrient requirements of mammalian cells are many, varied, and complex. In addition to typical metaboHc requirements such as sugars, amino acids (qv), vitamins (qv), and minerals, cells also need growth factors and other proteins. Some of the proteins are not consumed, but play a catalytic role in the cell growth process. Historically, fetal calf semm of 1—20 vol % of the medium has been used as a rich source of all these complex protein requirements. However, the composition of semm varies from lot to lot, introducing significant variabiUty in manufacture of products from the mammalian cells. 

Milk. Imitation milks fall into three broad categories filled products based on skim milk, buttermilk, whey, or combinations of these synthetic milks based on soybean products and toned milk based on the combination of soy or groundnut (peanut) protein with animal milk. Few caseinate-based products have been marketed (1,22,23). Milk is the one area where nutrition is of primary concern, especially in the diets of the young. Substitute milks are being made for human and animal markets. In the latter area, the emphasis is for products to serve as milk replacers for calves. The composition of milk and filled-milk products based on skim milk can be found in Table 10. Table 15 gives the composition of a whey /huttermilk-solids-hased calf-milk replacer, which contains carboxymethyl cellulose (CMC) for proper viscosity of the product. 

Generation of data on the nutrient content of agricultural products and foods forms the basis for estimating nutrient intakes of populations via dietary surveys, nutritional labelling for consumer protection, nutrition education for consumer food choice, home and institution menu planning and food purchase, and for research in nutrient requirements and metabolism, toxicant chemical composition is used to assess effects of farm management practices, crop culture, and food processing on chemical content and implications for human health.
