  2. Dextrin - Wikipedia

    en.wikipedia.org/wiki/Dextrin

    Dextrins are white, yellow, or brown powders that are partially or fully water-soluble, yielding optically active solutions of low viscosity. Most of them can be detected with iodine solution , giving a red coloration; one distinguishes erythrodextrin (dextrin that colours red) and achrodextrin (giving no colour).

  3. Starch gelatinization - Wikipedia

    en.wikipedia.org/wiki/Starch_gelatinization

    Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves the starch granule in water. Water acts as a plasticizer.

    Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...

    The digestion-resistant maltodextrin ingredient has several properties exploited in food or beverage manufacturing: it is a low-moisture (5% water), free-flowing, fine white powder that disperses readily in water; it is clear in solution with low viscosity; it is odorless, slightly acidic, and has a bland flavor; it is 90% dietary fiber.

    Sewage treatment plant (a type of wastewater treatment plant) in La Crosse, Wisconsin. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment.

    en.wikipedia.org/wiki/Β-cyclodextrin

    β-Cyclodextrin exists as a white (colorless) powder or crystals. The density of its saturated hydrate crystal (βCD·12H 2 O) is 1.46 g/cm 3 . β-Cyclodextrin is moderately soluble in water and glycerin ; well soluble in dimethyl sulfoxide , dimethylformamide , pyridine , HFIP , and ethylene glycol ; and insoluble in ethanol and acetone .

    en.wikipedia.org/wiki/Secondary_treatment

    Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [ 1 ] : 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.
