From functional properties to sensory quality: Integrating current knowledge on tapioca starch for food product development

Abstract

Physicochemical and instrumental characterization of tapioca starch has advanced considerably, generating detailed knowledge of its pasting behaviour, gelatinization profile, and response to chemical and physical modification. Whether these instrumental measurements reliably predict the technological and sensory quality of finished food products remains comparatively unresolved. This narrative review synthesizes current evidence on tapioca starch across four levels of investigation, intrinsic and physicochemical characteristics, functional and rheological properties, technological performance in food systems, and sensory quality, and examines the extent to which these levels have been empirically connected within the same body of work. The evidence indicates that each level is individually well studied: granule- and cultivar-level differences are linked to hydrolysis and gelatinization behaviour, a wide range of chemical and physical modifications produce predictable shifts in swelling, solubility, and pasting parameters, and these functional properties are traceable into bakery, meat, fish, and traditional Southeast Asian food systems. What is less consistently established is the final link between measured instrumental or technological performance and actual sensory acceptability. Across the studies reviewed, instrumental and sensory data are more often reported as parallel outcomes of the same formulation experiment than tested for a statistical relationship, with only a small number of exceptions demonstrating that such a relationship can be established directly. This review argues that the resulting evidence base is fragmented rather than scarce, reflecting largely separate research traditions in starch chemistry, food technology, and sensory science, and proposes that closing this gap, particularly for culturally significant Indonesian and Southeast Asian tapioca-based products, requires study designs that treat the instrumental-sensory relationship itself as the object of investigation rather than an assumed byproduct of formulation optimization.
