Plasticized starch processing

Starch products, paper and wood pulp, textiles, plastics, food processing fermentation. 

To coimter the loss of water dining the process and a significant degradation of the material, to prevent, e.g., the formation of cellular stractures output from an extruder, and to obtain a material with controlled properties, we use a non-volatile plasticizer such as glycerol or other polyols (sorbitol, xylitol, fructose, polyethylene glycol, etc.) [AVE 04a, XIE 12]. Blends of these different polyols are also used [CHI 10b]. Other, notably nitrogenous plasticizers (urea, ammonium derivatives, amines, etc.) can also be used. Plasticized starches are thus created. They are...

Glucans are useful as raw materials for starch processing industries, dietary compositions, compositions for food additives, adhesive compositions, inclusion compounds and absorbing compounds, medical and cosmetic compositions, film-type product compositions, and as an alternative for starches used in biodegradable plastics. Methods for the production of glucan have been described (4). The reaction starts from glucose and inorganic phosphate, such as... 

In addition, newer aspects, such as the effects of sustainable materials based on starch on the macro or nanostructure and subsequent processing, thermomechanical properties and performance properties of plasticized starch pol5mciers have been examined (10). Specific structures and the resulting properties are controlled by many specific factors, such as filler shape, size and surface chemistry, processing conditions and environmental aging. In case of nanosized biocomposites, the interfadal interactions are extremely important to the final nanostructures and performance of these materials. 

The phase separation process of blends has been studied by a number of researchers. Chaleat et al. investigated the phase separation of plasticized starch/ PVA blends (Chaleat 2012) blends of vinylidene fluoride/trifluoroethylene copolymer and poly(l, 4-butylene adipate) was studied by Kap Jin Kim and K5m (Kim and Kyu 1999). Fully biodegradable blends of poly(butylene succinate) and poly (butylene carbonate) and its phase behavior were studied by Wang (2012).
