“…There are products where moderate stickiness is desired by consumers (e.g., chewy candies) (Wagoner & Foegeding, 2018), and occasions when the adhesive properties of sugar-rich systems are exploited (e.g., nutritional bar binders and royal icing) (Holding, 1987;. However, when it comes to food processing, the occurrence of stickiness is usually undesired as it causes problems, such as (a) the mass of products sticks and leaves residue on equipment, causing diminished heat transfer, membrane fouling, and shutdown (Michalski et al, 1997); (b) hygroscopic sugars absorb moisture and render a tacky product surface (Nowakowski & Hartel, 2002); (c) caking of granular or powdery products over shelf life (Adhikari et al, 2001); (d) candy pieces attach to consumers' teeth, leading to dental caries (Caldwell, 1962;Khan et al, 1990); (e) unpleasant consumer experience originated from products clinging to packaging, fingers, and utensils (Hartel & Hartel, 2008); and (f) microbial adhesion to food-containing surfaces might cause general food safety concerns (Silva et al, 2008). These sticky situations call for extra attention and cost to maintenance, cleaning, packaging, surface treatment, and labor.…”
