Vegetables starch

Reserve polysaccharides serve as food reserves they are weakly or strongly branched and form compact macromolecules. The amylose and amylopectin of vegetable starches and the glycogen of animals belong in this class. Bacteria also use poly(/3-hydroxybutyrate), a linear polyester, as a food reserve.

The use of starch for the preparation of glucose syrups has led to a commercial success in the industrial production of this material [132], However, starch is chemically converted to dextrin or dextrose syrups. Crystalline dextrose (glucose) is the major product of the starch conversion industry from com, milo-maize, grain sorghum, and other vegetable starches with acid under pressure and at high temperature [133], Starch hydrolysis is an equilibrium reaction and depending upon the... 

There are three chemical compounds that form the building blocks of food carbohydrates, hits (or hpids), and proteins. Carbohydrate molecules, which are found in fruits, vegetables, starches, and dairy products, consist of atoms of carbon, hydrogen, and oxygen, chemically bonded in a ratio of 1 2 1. Monosaccharides and disaccharides such as glucose, fructose, and sucrose have just one or two molecules of this kind and are known as simple sugars. Polysaccharides like starch, glycogen, and cellulose (an important component of dietary fiber) have several carbohydrate molecules and are known as complex... 

Polysaccharides are macromolecules which make up a large part of the bulk of the vegetable kingdom. Cellulose and starch are, respectively, the first and second most abundant organic compounds in plants. The former is present in leaves and grasses the latter in fruits, stems, and roots. Because of their abundance in nature and because of contemporary interest in renewable resources, there is a great deal of interest in these compounds. Both cellulose and starch are hydrolyzed by acids to D-glucose, the repeat unit in both polymer chains. 

Proteia and starch stains are removed by proteases and amylases, respectively. Fats and oils are generally difficult to remove at low wash temperatures by conventional detergents. By usiag Upases, it is possible to improve the removal of fats/oils of animal and vegetable origin even at temperatures where the fatty material is ia a soUd form. Particulate soils can be difficult to remove, especially if the particle sise is small. Removal of particulate soil from cotton fabric can be improved by use of a ceUulase which removes cellulose fibrils from the surface of the yam. 

Casein is the only protein that has achieved commercial significance as a plastics raw material. Many other proteins are readily available in many vegetable material residues which arise from such processes as the extraction of oils and starches from seeds. It would be advantageous to countries possessing such residues if plastics could be successfully exploited commercially. Although plastics materials have been produced they have failed to be of value since they are invariably dark in colour and still have the water susceptibility and long curing times, both of which are severe limitations of casein.

The SF-837 strain, namely Streptomyces mycarofaciens identified as ATCC No. 21454 was inoculated to 60 liters of a liquid culture medium containing 2.5% seccharified starch, 4% soluble vegetable protein, 0.3% potassium chloride and 0.3% calcium carbonate at pH 7.0, and then stir-cultured in a jar-fermenter at 28°C for 35 hours under aeration. The resulting culture was filtered directly and the filter cake comprising the mycelium cake was washed with dilute hydrochloric acid. 

There may be more than one hydroxyl group in an organic molecule. Polyalcohols are widely found in nature as all starchs and sugars are polyalcohols including sucrose (table sugar), and all fats, both vegetable and animal, are derivatives of glycerine. 

With few exceptions, small particles of vegetable foods are generally stripped of their more accessible nutrients during digestion in the GI tract. In this way starch, protein, fat and water-soluble small components (sugars, minerals) are usually well absorbed. This is not always the case, however, for larger food particles or for molecules that cannot diffuse out of the celF tissue. Neither is it the case for the lipid-soluble components. These need to be dissolved in lipid before they can be physically removed from the cell to the absorptive surface, since the cell wall is unlikely to be permeable to lipid emulsions or micelles, and the presence of lipases will strip away the solvating lipid.
