Wheat distribution

Hexachlorobenzene is a seed protectant used on wheat. Contact with hexachlorobenzene may cause slight skin irritation. Hexachlorobenzene produced an epidemic of severe porphyria cutanea tarda in Turkey from 1955-1959. The disease occurred almost exclusively in persons who admitted eating wheat distributed for seed not for food. This wheat had been treated with hexachlorobenzene. Many infants died from exposure to hexachlorobenzene in this epidemic [80]. 

Starch is a widely distributed material which occurs in roots, seeds, and fruits of plants. For commercial use, com is the principal source, though wheat and potatoes are also used. Starch is extracted by grinding with water, filtering, centrifuging, and drying, a process which yields starch in a granular form.

Recently, pulse labeling has frequently been applied to determine the fate of carbon in crops such as barley and wheat and the losses from roots and subsequent microbial transformations. In general, the results indicate that 15-25% of the net " C assimilation is transferred to the roots and that there are seasonal differences in the distribution of assimilated carbon. Meharg and Killham (25) measured the C distribution in perennial ryegrass (L perenne). At 8 days after the pulse with...

Commercial production of food products is conducted in large-scale processing plants. As already mentioned, tomatoes are processed in plants continuously from June to late fall (autumn), 24 h per day, 7 days per week. This is also true of potatoes, wheat, soybeans, corn, and other large-scale commodity crops. Some crops, such as grapes, that might have a relatively short harvest season, may be processed around the clock to generate intermediate products, such as juice or young wine that can be stored for extended periods of time, whereas final products, which can be made from the intermediate products, may be produced over time as consumer demand requires. Final products may also be stored in their final retail or food service containers until demand requires distribution.

One might well imagine that the primary structures for proteins serving the same function in different species would most resemble each other for species that are closely related in an evolutionary sense. Such proteins are termed homologs. This turns out to be the case. Cytochrome c is a protein very widely distributed throughout nature. The primary structure for the cytochrome c of humans is very similar to that from pigs but not quite so similar to that from frogs and even more distantly related to that from insects and, at the extreme, that of wheat. 

Kovacova (1990) describes a method for the batch drying of fruit and vegetable pulp in a fluidized bed in which carrier particles (variously crystalline and caster sugar, dried skim milk, potato and wheat starch, apple powder, semolina or oat flakes), pre-moistened to a solids content of between 55% and 76%, are fed to a preheated fluidized bed and sprayed with the pulp to be dried. A product with a narrow particle size distribution and a uniform pulp content is claimed. Specific foods for which fluidized bed granulation has been used include potato puree (Zelenskaya and Filipenko, 1989) and granulated dried apple (Haida et al, 1994). 

Distribution of compounds in barley and wheat tissues. Tissues of barley and wheat leaves were mechanically separated under the microscope. It was observed that in barley gramine was more concentrated in the epidermis than in the entire leaf (Table II). Hydroxamic acids in wheat were absent in epidermic tissues and were more concentrated in the vascular tissues than in the entire leaf. Neither compound was detected in xylem exudates nor in guttation drops.
