• Product description :

  The hydrophobic cavity and the hydrophilic outer surface of alpha-cyclodextrin form the basis for its use in the food industry. alpha-Cyclodextrin, like its homologues beta- and gamma-cyclodextrin, can function as 1.A carrier and stabilizer for flavors, colors, and sweeteners;

  2.An absorbent for suppression of undesirable flavors and odors in foods;

  3.An absorbent for suppression of halitosis (in breath-freshening preparations);

  4.A water- solubilizer for fatty acids and vitamins
