Extractive starch

Its use was first reported in 1985 by Meuser et al.98 for extracting starch from com. The HD process for commercial production of wheat starch and wheat gluten is used in many countries in Europe and in Australia, Canada, Mexico, India and Venezuela. 

Iodometric assay of amylose on cereal starches is most often done on lipid-extracted starch, and the amylose content from that assay is termed apparent amylose 145 or total amylose. 123 When the iodometric assay is performed on a lipid-extracted starch and the amylose content is corrected for interference from extra-long chains on amylopectin, the assay gives absolute amylose or real amylose. 145 Iodometric assay of starch that has not been lipid-extracted gives lipid-free (uncomplexed) amylose. Subtraction of total amylose from lipid-free amylose gives lipid-complexed amylose.123 The use of the term apparent amylose to designate lipid-free amylose is avoided in this chapter. All amylose percentages are calculated based on starch.

Henderson and Rudin111 examined the effects of water on starch-PMA and starch-g-PS extrudates of similar add-on. When immersed in water, starch-g-PS gained approximately 9% in weight and 7% in cross-section area, with essentially no water extractables. Starch-g-PMA gained 25% in weight and 50% in cross-section under the same immersion conditions. Extractables for the starch-g-PMA were 12.4%. Water absorption significantly reduced the tensile strengths of the copolymers the...

Starch can be obtained in a great variety of crops, the choice of the botanical resource depending mainly on geographic and climatic factors and on the desired functional properties of the extracted starch [5]. It is always possible to find a highly productive plant to produce starch whatever the climate and agricultural conditions, such as maize in temperate and subtropical zones, cassava (the same as manioc or tapioca) in tropical regions, rice in inundated areas, and wheat or potatoes in temperate and cold climates. The main plant sources are maize, rice, wheat, potatoes and cassava [6]. In the year 2005, worldwide starch production accounted for approximately 58 million tons. 

All crops have a carbohydrate corrtent but the ones of most interest for commercially extractable starch or other products include rrraize, wheat, sugar beet, potatoes and barley. There may be the potential to develop more esoteric crops such as quinoa, sorghum and chicory for starch production. 

Commercial Starch. Commercially extracted starch, due to some unique chemical and physical properties, low cost, and availability, may be added to foods during processing—as a food additive. While many plants produce starch, only a few produce it in quantities to make extraction feasible. 

Etienne Ossian-Henry (Paris 27 November 1798-24 August 1873), director of the laboratory of the Academy of Medicine in Paris, published on the analyses of mineral waters, adulteration of wheat flour with potato starch, nitrogenous organic substances, the analysis of a biliary calculus free from cholesterin, and many papers of pharmaceutical interest. His a ysis of jalap showed that it contained resin, extract, starch, and woody fibre he also analyst horse-chesnut bark, which had been piopos as a substitute for quinine. 

The cereal seeds, tubers, starch storage roots, and bean/pea seeds are directly consumed as food in human diet or animal feed and are used as a source of starch. Extracted starch can be used to produce starch derivates or hydrolyzed to produce soluble sugars, food additives, or glucose syrup. Also, extracted starch can be used for other applications in nonfood industries (Nghiem et al. 2011). For example, it is used as a thickener and as a source of renewable raw material for bioethanol production. The major source of starch for the world market is cornstarch holding more than 80 % of the market, but wheat, potato, cassava or tapioca, and to a lesser extent rice and sweet potato starches are also commercialized (Thomsen et al. 2008). 

Domains of Application of Starch and its Derivatives. Apart from its direct utilization in food applications, extracted starch is an important industrial product, due to its hydrophilicity, a property that can be used in many respects. Thus, it can serve as viscosilying agent in human or animal food and in the pharmaceutical industry. It is also utilized in the manufacturing processes of...
