To help understand the organoleptic qualities of steam cooked foods, the kinetics of aroma release during cooking in a potato starch based model matrix was studied. Behaviour of components having a major impact in potato flavour were studied using solid phase micro extraction-gas chromatography (SPME-GC). Evolution of microstructure of potato starch model-matrix during steam cooking process was analyzed using environmental scanning electron microscopy (ESEM). Both aroma compounds that are naturally present in starch matrix and those that were added were analyzed. Both the aroma compounds naturally presented and those added had different behaviour depending on their physico-chemical properties (hydrophobicity, saturation vapour pressure, molecular weight, etc.). The physical state of potato starch influences of the retention of aromatized matrix with Starch gelatinization appearing to be the major phenomenon influencing aroma release.

Recent studies have focused on the generation of biomaterials from natural sources, highlighting the use of starch from different sources to obtain edible films and coatings. In this study, edible films were developed from sweet potato starch, and their potential use in candy packaging was evaluated. Films were prepared by the casting method, and the effects of sweet potato starch (3 %-5 % w/w), glycerol (0.

Starch degradation and wound healing occur in potato tubers following fresh-cut processing, and ascorbic acid (AA) treatment can suppress these processes, though the underlying regulatory mechanisms remain unclear. This study investigated the effects of 5 g L AA treatment on the multiscale structural changes and metabolic responses of starch during wound healing in fresh-cut potatoes. The results revealed that AA treatment delayed starch degradation and reducing sugar accumulation while promoting sucrose and fructose accumulation.

Introduction: Sweet potato is an important food, feed and industrial raw material, and its tubers are rich in starch, carotenoids and anthocyanins.
Methods: To elucidate the gene expression regulation and metabolic characteristics during the development of sweet potato tubers, transcriptomic and metabolomic analyses were performed on the tubers of three different sweet potato varieties at three developmental stages (70, 100, and 130 days (d)).
Results: RNA-seq analysis revealed that 16,303 differentially expressed genes (DEGs) were divided into 12 clusters according to their expression patterns, and the pathways of each cluster were annotated.

In this study, the influence of tannic acid (TA)/soluble potato starch (PS) mass ratio and PS concentration on TA/PS complexes and emulsions stabilized by TA/PS complexes were studied. The size, hydrophobicity and emulsifying properties of TA/PS complexes were all controlled by TA/PS mass ratio and PS concentration. In detail, the hydrophobicity of PS (θ = 48°) improved after complexing with TA to form TA/PS complexes (θ = 64°).
