“…However, heat, particularly coupled with excess water as in boiling, solubilizes starch, so that salivary amylase, which humans have in variable abundance (3), can act inside 1 s rather than after many hours. Food scientists attribute many important oral sensations in humans to this enzymic activity, including the coating and decoating of the oral mucosa to produce impressions of "creaminess" and "thickness" in semisolid starchy foods (4,5). Dental researchers suspect that sticky types of cooked starch, coupled with the tendency of salivary amylase to bind to enamel surfaces (6), may result in both becoming trapped in dental plaque, leading to a maltose sugar product and potential caries (i.e., tooth decay).…”
