This study examines the preparation of starch-phenolic acid complexes using potato, corn, and pea starches to understand how the botanical source influences their structure and digestibility. The research demonstrates that the starch source and phenolic acid type synergistically affect the complex architecture and enzymatic resistance. These findings contribute to the development of potato-derived digestion-resistant food ingredients.
This study investigates how starch granules from potato, maize, and wheat affect disulfide bond formation in urea-solubilized glutenin (USG) within wheat-based dough systems. The findings reveal that potato starch granules interact with USG through hydrogen bonding and physical entanglement, altering the protein's conformation and disulfide bond content. This research provides a mechanistic basis for optimizing the quality of cereal-based food products supplemented with potato starch.
This study analyzes the N-glycosylation profiles of patatin, the major storage protein in potato tubers, across three different cultivars using mass spectrometry. The researchers identified cultivar-specific variations in N-glycan structures and abundances, including two novel glycan structures. These findings provide valuable glycomic data to support potato germplasm screening and the functional modification of potato proteins.
This study investigates the molecular, chemical, and microstructural properties of starch-polyphenol complexes using starches from wheat, rice, potato, and maize. The findings reveal that polyphenols, particularly epigallocatechin gallate and quercetin, alter starch molecular organization and morphology through hydrogen bonding. These insights support the development of potato-derived and other starch-based functional foods with enhanced nutritional properties.
This study evaluates the response of six potato (Solanum tuberosum) cultivars to potassium fertilization under drought stress, identifying significant genotypic differences in yield and starch content. The researchers classified the cultivars based on their potassium efficiency and drought tolerance, highlighting cultivar 'SY-2' as a valuable genetic resource for future breeding programs.
This study investigates the role of the StABI5-StCAT1 module in regulating potato resistance to early blight caused by Alternaria solani. The authors demonstrate that StCAT1 acts as a positive regulator of resistance by modulating hydrogen peroxide (H2O2) levels and antioxidant enzyme activities. Furthermore, the transcription factor StABI5 was identified as an upstream activator of StCAT1, providing potential genetic targets for breeding disease-resistant potatoes.
This study evaluates the viscoelastic properties and cellular structure damage of Bellarosa potato tissue under various deformation velocities using stress relaxation tests. The findings describe how loading conditions affect water movement and mechanical behavior in potato tubers, which is relevant to potato food science and post-harvest handling.
This study optimized wet-process starch extraction from rejected Solanum tuberosum (Pastusa variety) using a Box-Behnken design. Under optimal conditions (40 °C, 1:4 w/v ratio, and 3% citric acid), rejected-grade tubers yielded significantly more starch than standard-grade tubers. The extracted starch was validated as native amylose-rich starch, highlighting the potential of rejected potatoes for circular-economy starch recovery.
This study evaluates the use of choline dihydrogencitrate (CCT) as a plasticizer for potato starch-based films. The results show that CCT disrupts the crystalline structure of potato starch, enhancing film flexibility and reducing moisture sensitivity, which is promising for packaging applications.
This study investigates the dissolution and esterification of potato starch using environmentally friendly water-modified deep eutectic solvents (DESs). The water-containing DES showed high dissolution efficiency at mild temperatures, successfully disrupting the starch's crystalline structure and allowing for efficient chemical modification without additional catalysts.
