摘要: Abstract The effect of chitosan on the crystallization behavior lactose has been studied during spray drying lactose/chitosan solutions. Solutions with different ratios and have dried at an inlet temperature 160 °C using a laboratory-scale dryer. Water-induced crystallization, X-ray diffraction analysis differential scanning calorimetry used to study crystallinity spray-dried powders. Results show that, despite ability retain moisture for longer time drying, powders were in amorphous form. Moisture-induced results suggest that presence delays crystallization. This finding may be due high glass-transition chitosan, its hydrogen bond water, which was suggested previously by other researchers reason crystallizing polyethylene glycol.
