Alpha-cyclodextrin is a non-reducing cyclic oligosaccharide composed of six glucose units linked by α-1, 4-glycosidic bonds [1]. It is derived from starch, typically through enzymatic conversion [2]. Generally, it is utilized to encapsulate, protect, and deliver functional ingredients in various applications [3].
Alpha-cyclodextrin is produced through the enzymatic degradation of starch, using cyclodextrin glycosyltransferase (CGTase) [4]. The enzyme catalyzes the formation of cyclic structures from linear starch molecules, resulting in a mixture of cyclodextrins [4]. Purification processes, such as crystallization or chromatography, are then employed to isolate alpha-cyclodextrin from the mixture [5].
Alpha-cyclodextrin can form inclusion complexes with various guest molecules, enhancing their water solubility, stability, and bioavailability [6]. It can also reduce the volatility of aroma compounds and mask unpleasant tastes or odors in food products [7]. Additionally, it exhibits prebiotic effects, promoting the growth of beneficial gut bacteria [8].
Alpha-cyclodextrin finds applications in food products like beverages, baked goods, and confectionery items to improve the stability and delivery of flavors, colors, and nutrients [9]. In the pharmaceutical industry, it is used to enhance the solubility and bioavailability of drugs [10]. Cosmetic formulations also utilize it for fragrance encapsulation and controlled release of active ingredients [11].
Alpha-cyclodextrin is commonly packaged in multi-layer paper bags with polyethylene liners or cardboard drums with polyethylene liners, with sizes ranging from 10 kg to 25 kg [12]. The product should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and moisture, to maintain its quality and prevent degradation [12].
