[PMID: 39332370 DOI: 10.1016/j.foodchem.2024.141380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Revised: 08/30/2024] [Accepted: 09/19/2024] [Indexed: 09/29/2024]
Abstract
This study investigated the effects of konjac glucomannan (KGM) and ultrasound on the solubility, pasting properties, rheological behavior, thermal properties, structural characteristics, and digestibility of quinoa starch. The results demonstrated significant improvements in starch properties with both ultrasound and KGM treatment, with the most pronounced effects observed in the combined ultrasound and KGM treatment. This combined treatment led to enhanced energy storage modulus and loss modulus, indicating improved rheological properties. Additionally, combined treatment improved solubility, thermal stability, and digestibility and resulted in a more ordered structure and increased paste enthalpy compared with ultrasound or KGM treatment. Scanning electron microscopy and particle size analysis revealed a more compact starch structure following the synergistic treatment. X-ray diffraction and Fourier transform infrared spectroscopy showed a more organized, complex structure. These findings offer valuable insights into the application of ultrasound and KGM to enhance the performance and quality of quinoa starch.

Sindhu R, Khatkar BS. Influence of oxidation, acetylation and hydrothermal treatment on structure and functionality of common buckwheat starch. Int J Biol Macromol 2023; 253:127211. [PMID: 37797848 DOI: 10.1016/j.ijbiomac.2023.127211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 08/14/2023] [Accepted: 10/01/2023] [Indexed: 10/07/2023]
Abstract
The set aim of present work was to investigate the effects of acetylation, oxidation and heat moisture treatment on physicochemical, pasting, gel texture, structural, thermal and morphological properties of common buckwheat starch. Swelling power and solubility of starches reduced after modification except acetylation. Color of buckwheat starch improved after oxidation and acetylation. Paste clarity increased while syneresis reduced following modification with the exception of oxidation. Pasting properties of buckwheat starch revealed increased peak viscosity and breakdown viscosity following modification treatments. Gel texture analysis depicted increased hardness and reduced springiness, chewiness and cohesiveness for modified starches of buckwheat. Diffractograms of starches showed variation in intensity of some bands. Heat moisture treatment increased agglomeration and oxidation caused slight depression on surface of some granules. Relative crystallinity reduced following oxidation and hydrothermal treatment of starch. The gelatinization temperatures were increased in hydrothermal treated starch samples while oxidation and acetylation reduced the gelatinization temperature. The findings of this work would favor the new applications of modified starch from common buckwheat.

Foods 2023; 12:foods12020335. [PMID: 36673427 PMCID: PMC9858123 DOI: 10.3390/foods12020335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 12/30/2022] [Accepted: 01/04/2023] [Indexed: 01/12/2023] Open
Abstract
To investigate the effects of repeated dry heat treatment (RDH) and continuous dry heat treatment (CDH) on the structure and physicochemical and digestive properties of potato starch, potato starch was treated continuously and repeatedly at 130 °C for 3-18 h. The results showed that the crystalline form of starch was consistent with the original type B. Still, its physicochemical properties, such as swelling power, transparency, peak viscosity (PV), final viscosity (FV), breakdown (BD) and thermal properties (To, Tp, Tc, ΔT), tended to decrease. At the same time, solubility and RS increased after dry heat treatment. Moreover, RDH-treated starches were higher than CDH-treated ones in terms of molecular weight, crystallinity, swelling power, transparency and final viscosity for the same treatment time. Still, there was no significant difference between the thermal properties of the two. Meanwhile, the resistant starch (RS) content showed a downward trend after the peak value of 9 h of CDH treatment and five cycles of RDH treatment with increasing treatment time and the number of cycles, indicating a decrease in the overall digestibility of the starch. Overall, RDH had a more significant effect on potato starch's structure and physicochemical properties than CDH.

Int J Biol Macromol 2022; 222:636-651. [PMID: 36174856 DOI: 10.1016/j.ijbiomac.2022.09.191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 09/03/2022] [Accepted: 09/21/2022] [Indexed: 11/05/2022]
Abstract
The Chenopodium genus includes >250 species, among which only quinoa, pigweed, djulis, and kaniwa have been explored for starches. Chenopodium is a non-conventional and rich source of starch, which has been found effective in producing different classes of food. Chenopodium starches are characterized by their smaller granule size (0.4-3.5 μm), higher swelling index, shorter/lower gelatinization regions/temperature, good emulsifying properties, and high digestibility, making them suitable for food applications. However, most of the investigations into Chenopodium starches are in the primary stages (isolation, modification, and characterization), except for quinoa. This review comprehensively explores the major developments in Chenopodium starch research, emphasizing isolation, structural composition, functionality, hydrolysis, modification, and application. A critical analysis of the trends, limitations, and scope of these starches for novel food applications has also been provided to promote further scientific advancement in the field.
