A minimum temperature of 88°C is required for paste storage of thermally oxidized starch in order to prevent retrogradation. Various retrogradation control agents have been recommended for stabilizing. The addition of 0.5 to 1.0% calcium stearate prevents the build up of viscosity, but could actually lead to the precipitation of amylose due to gradual stearate dissolution (ionization) and complex formation with... 

Norfloxacin can interact with antacids containing aluminium or magnesium salts, by complexation, reducing its solubility and therefore its absorption this can result in therapeutic failure. In an in vitro study, dissolution rates were markedly reduced in the presence of all antacids studied however, this phenomenon was practically avoided when a disintegrant (sodium starch glycolate or crospovidone) was included in the tablet (13). 

Phase transitions of starch-Upid complexes are also seen in calorimetric curves. These weak endothermic phenomena occur around lOOX and have enthalpies of less than 30 J/g DM [57]. Sometimes interactions between water and the foods or food constituents (dissolution, absorption, or desorption) in addition to interactions of cations and sugars in water are studied [102-104]. 

Sugar cane waste is another raw material that can be treated in a hot solution of concentrated acetic acid in hydrochloric acid solution. After re-concentration, the lignin is then precipitated in warm water and finally recovered by dissolution in acetone. Due to all this complex chemistry, the major commercialised wood polymers are blends. These plastics contain wood powder, starch or lignin. The presence of lignin as a filler in other polymers improves the quahty of the biodegradation. Some of those products are reinforced with flax or hemp.
