Cereals wheat

Since most snack foods are based on cereals (wheat, corn, rice), a great deal of attention has focused on fortification/supplementation of traditional cereal-based foods. Worldwide, cereals represent the major source of calories and proteins for humans i.e. 52% and 47% of the world s average per capita... 

Most of the applications of HPLC for protein analysis deal with the storage proteins in cereals (wheat, corn, rice, oat, barley) and beans (pea, soybeans). HPLC has proved useful for cultivar identihcation, protein separation, and characterization to detect adulterations (illegal addition of common wheat flour to durum wheat flour) [107]. Recently Losso et al. [146] have reported a rapid method for rice prolamin separation by perfusion chromatography on a RP POROS RH/2 column (UV detection at 230nm), sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE), and molecular size determination by MALDl-MS. DuPont et al. [147] used a combination of RP-HPLC and SDS-PAGE to determine the composition of wheat flour proteins previously fractionated by sequential extraction.

The direction and magnitude of the changes in production and returns will differ between countries. In the UK, for example, Lampkin (1994) estimated that with a 10% increase in organic agriculture, there would be a decrease in wheat, barley, potatoes, sugar beet, oilseed and livestock and an increase in oats and field beans. In Australia, on large-scale cereal-live-stock farms, large-scale conversion would lead to decreased total production of all cereals (wheat, oats, barley, canola), and an increase in sheep (Wynen 1997). 

This change in farming practices can also be observed by comparing labor units per hectare of land used in agriculture. In the Federal Republic of Germany, labor unlts/ha were 29 in 1950 and only 7.9 in 1982. This reduction parallels an increase in combine harvested crops, especially winter cereals (wheat and barley). 

Although cationic com, tapioca, wheat and potato starches are the most common commercial products, preparations, properties and performance of cationic oat31 and pea32 starches have been reported. Improved retention performance via the use of a blend of cationic cereal (wheat, com) starch and cationic potato starch has been reported.33 Products for papermaking using all-amylopectin potato starch have been proposed.34-39...

A rather simplified breakdown of the total agricultural harvest of 4.2 Gt C-equivalent is outlined in Fig. 4, Half of the arable land (total 14 million km ) is cultivated for cereals wheat, rice, maize and barley make up about 90% of all grain. The known world grain harvest in 1998 amounts to 2.1 Gt. From the average grain/straw ratio of ca. 1, the world straw harvest can be estimated to be about the...

Fructans are oligomers and polymers formed by polymerizing fructose from transport metabolite sucrose on one out of three possible starter trioses 1-kestose yields inulin-type (2 1)-p-D-fructans, 6-kestose yields levan-type (2 6)-p-D-fructans (Fig. 3A), and neo-kes-tose yields mixcD-type and/or branched (2 1), (2 6)-p-D-fructans (Fig. 3C). Pronounced fructan metabolism is found in composites (chicory, Jerusalem artichoke), Liliaceae (onion, chives, garlic), cereals (wheat, barley, rye, oat), Asparagaceae (asparagus), Amaryllidaceae (banana), and Agavaceae (agave). 

The imaging of photon emission from the ROS/hydrogen donor/mediator system was applied to solid-type samples. We studied the photon emission of several foods. Hydrogen donor emission (Y emission) was observed from polyphenol rich vegetables and fruits (tea and banana), fermented foods (oyster sauce, soy sauce and miso), alcohol (wine, sake and beer), spices and cereals (wheat and rice). Mediator emission (Z emission) was seen from some vegetables (Japanese radish, Chinese yam and nozawa-na) and fruits (melon), egg white, meat and fish meat. Imaging detection has a potential for visualization of Y and Z component distribution through the Y and Z emission...

Both diallate and triallate active substances are liquids of medium vapour pressure they must therefore be incorporated into the soil to a depth of about S cm to attain a satisfactory herbicidai effect. They are absorbed mainly through the developing coleoptile, and are used at a rate of 1.5-4 kg active ingredient/ha for the control of wild oat (Avenafatua) and hl ckg ass (Alopecurus mysuroides). Crops tolerant to diallate are root crops, sugar beet, fodder beets, maize, leguminous plants and fruit trees triallate is selective in cereals, wheat and barley (Monsanto,...

Cereals (wheat, barley, sorghum, oats, rye and triticale) are the most important of the arable crops (Table 2.2.4). In 2005, global cereal production was approximately 870 mio tonnes on 340 mio hectares of land, with wheat Triticum aestivum) being the most important cereal grain, accounting for more than two-thirds of the total production (Table 2.2.5). 

L-Lysine< Lys 2,6-diaminocaproic add, H2N-(CH2)<-CH(NH2)-C00H, a basic proteogenic, essential amino acid, Af, 146 2, m.p 224 °C (d), [0] - 25.9° (e = 2 in 5 M HQ),-r 13.5° ( c = 2, water). The proteins of cereals (wheat, barley, rice) and other vegetable foodstuffs are rather poor in Lys. Children and young growing animals have a particularly high requirement for Lys, since it is needed for bone formation. Like threonine, Lys does not take part in reversible transamination. 

Compared to the worldwide distribution of DON, NIV contamination is found only in limited areas. In Fig. 100.5, the commodities contaminated with NIV that have been reported are plotted [120]. Contamination of cereals (wheat, oats, barley, maize, rice, rye) has been frequently found in Far East Asia (China, Korea, Japan), Southeast Asia (the Philippines, Vietnam), Oceania (New Zealand, Australia) Europe (Germany, Poland, Norway, the Netherlands), and Eastern Europe (Lithuania). The contamination of soybeans (50 pg/kg of NIV) has also been reported in Australia [121]. 

The seed is dispersed from the mother plant endowed with a store of food reserves of protein, carbohydrate and fat in a more concentrated package than occurs anywhere else on the plant. Animals exploit this property when using seeds as an extremely important part of their diet. It is also debatable that civilization began its development when man started to cultivate plants for the food that their seeds provided, especially the cereals—wheat and barley in the Near East and Europe, rice in Asia and maize in the Americas. It need hardly be necessary to remind the reader, moreover, that virtually all of man s exploitation of plants in agriculture depends upon seeds —that they can be stored, transported, multiplied and, most important of all, germinated ...
