Kamut
Khorasan wheat or Oriental wheat (''Triticum turgidum'' ssp. ''turanicum'' also called ''Triticum turanicum''), commercially known as Kamut, is a tetraploid wheat species. The grain is twice the size of modern-day wheat, and has a rich, nutty flavor. Taxonomy Original botanical identifications were uncertain. The variety is a form of ''Triticum turgidum'' subsp. ''turanicum'' (also known as ''Triticum turanicum''), usually called Greater Khorasan, Khorasan wheat. Identifications sometimes seen as ''T. polonicum'' are incorrect as the variety, although long-grained, lacks the long glumes of this species. Recent genetic evidence from DNA fingerprinting suggests that the variety is perhaps derived from a natural hybrid between ''Durum, T. durum'' and ''T. polonicum'', which would explain past difficulties in arriving at a certain classification. Life form As an Annual plant, annual, self-fertilized grass that is cultivated for its Food grain, grains, Khorasan wheat looks ver ...

Proteins
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residues ...

B Vitamins
B vitamins are a class of water-soluble vitamins that play important roles in cell metabolism and synthesis of red blood cells. Though these vitamins share similar names (B1, B2, B3, etc.), they are chemically distinct compounds that often coexist in the same foods. In general, dietary supplements containing all eight are referred to as a vitamin B complex. Individual B vitamin supplements are referred to by the specific number or name of each vitamin, such as B1 for thiamine, B2 for riboflavin, and B3 for niacin. Some are more commonly recognized by name than by number, for example pantothenic acid, biotin, and folate. Each B vitamin is either a cofactor (generally a coenzyme) for key metabolic processes or is a precursor needed to make one and is thus an essential nutrient. List of B vitamins Note: other substances once thought to be vitamins were given numbers in the B-vitamin numbering scheme, but were subsequently discovered to be either not essential for life or manufact ...

Dietary Fiber
Dietary fiber (in British English fibre) or roughage is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes. Dietary fibers are diverse in chemical composition, and can be grouped generally by their solubility, viscosity, and fermentability, which affect how fibers are processed in the body. Dietary fiber has two main components: soluble fiber and insoluble fiber, which are components of plant-based foods, such as legumes, whole grains and cereals, vegetables, fruits, and nuts or seeds. A diet high in regular fiber consumption is generally associated with supporting health and lowering the risk of several diseases. Dietary fiber consists of non- starch polysaccharides and other plant components such as cellulose, resistant starch, resistant dextrins, inulin, lignins, chitins (in fungi), pectins, beta-glucans, and oligosaccharides. Food sources of dietary fiber have traditionally been divided according to whether they provide s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Essential Nutrients
A nutrient is a substance used by an organism to survive, grow, and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi, and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures, such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted to smaller molecules in the process of releasing energy, such as for carbohydrates, lipids, proteins, and fermentation products (ethanol or vinegar), leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from their host. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daily Value
The Reference Daily Intake (RDI) used in nutrition labeling on food and dietary supplement products in the U.S. and Canada is the daily intake level of a nutrient that is considered to be sufficient to meet the requirements of 97–98% of healthy individuals in every demographic in the United States. While developed for the US population, it has been adopted by other countries, though not universally. The RDI is used to determine the Daily Value (DV) of foods, which is printed on nutrition facts labels (as % DV) in the United States and Canada, and is regulated by the Food and Drug Administration (FDA) and by Health Canada respectively. The labels "high", "rich in", or "excellent source of" may be used for a food if it contains 20% or more of the RDI. The labels "good source", "contains", or "provides" may be used on a food if it contains between 10% and 20% of the RDI. The Recommended Dietary Allowances (RDAs) were a set of nutrition recommendations that evolved into both the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Food Energy
Food energy is chemical energy that animals (including humans) derive from their food to sustain their metabolism, including their muscle, muscular activity. Most animals derive most of their energy from aerobic respiration, namely combining the carbohydrates, fats, and protein in nutrition, proteins with oxygen from air or dissolved in water. Other smaller components of the diet, such as organic acids, polyols, and ethanol (drinking alcohol) may contribute to the energy input. Some diet (nutrition), diet components that provide little or no food energy, such as water, dietary mineral, minerals, vitamins, cholesterol, and dietary fiber, fiber, may still be necessary to health and survival for other reasons. Some organisms have instead anaerobic respiration, which extracts energy from food by reactions that do not require oxygen. The energy contents of a given mass of food is usually expressed in the International System of Units, metric (SI) unit of energy, the joule (J), and its ...

Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Grain Quality
In agriculture, grain quality depends on the use of the grain. In ethanol production, the chemical composition of grain such as starch content is important, in food and feed manufacturing, properties such as protein, oil and sugar are significant, in the milling industry, soundness is the most important factor to consider when it comes to the quality of grain. For grain farmers, high germination percentage and seed dormancy are the main features to consider. For consumers, properties such as color and flavor are most important. Properties of grain quality Overall quality of grain is affected by several factors, including: growing practices, time and type of harvesting, postharvest handling, storage management and transportation practices. The properties of grain quality can be summarized into ten main factors, (i) Uniform moisture content, (ii) High test weight, (iii) No foreign material, (iv) Low percentage of discolored, broken and damaged kernels, (v) Low breakability, (vi) Hi ...
