Abstract An increase in the occurrence of diabetes mellitus, cardiovascular disease and obesity in recent years led to the project “Starch retrogradation in tuber: mechanisms and its implications on microstructure and glycaemic features of potatoes”. Potato products can play a role in mitigating these hyperglycaemic events, if starch in these processed products is slowly digested and/or starch-derived glucose is released into the circulation in a slower and more attenuated manner. Three stages were envisaged for the project with an aim to create slowly digestible starch in whole potato tuber (in tuber) through starch retrogradation.

In all the starch samples, the UFW content increased with increasing hydration level. Potato starch samples (native, pregelatinized and retrograded) had higher UFW contents than wheat starch samples at all hydration levels. Similarly, with the increase of hydration level in all starch samples, onset (To), peak (Tp) and endset (Te) temperatures of the peaks also increased. It was obtained that physical modifications in starches had significant effects (P<0.05) on water absorption index (WAI) and water solubility index (WSI) of starch samples. The highest WAI (10.51) and WSI (2.31) values were determined in pregelatinized potato starches. Rapid Visco Analyzer (RVA) profiles revealed that physically modified starches had higher viscosity values than native starches.

  • Effects of Retrogradation on the Nutritional and Starch Characteristics of Some Foods
    World Journal of Medical Sciences 16 (3): 128-133, 2019 ISSN 1817-3055 © IDOSI Publications, 2019 DOI: 10.5829/idosi.wjms.2019.128.133 Effects of Retrogradation on the Nutritional and Starch Characteristics of Some Foods 12Oko Augustine Okpani and Ahamefule Augustus Kelechi 1Department of Biotechnology, Ebonyi State University, Abakaliki, Nigeria 2Department of Biotechnology, Federal University of Technology, Owerri, Nigeria Abstract: The changes that starch undergoes during retrogradation are major determinants of its functional properties for food processing, during digestion and in industrial applications. These properties determine the quality, acceptability, nutritional value and shelf-life of the finished food products. This research was carried out to evaluate the effects of retrogradation on different nutritional components of six selected starchy foods. Fresh tubers of white Yam (D. rolundata), Cassava (Manihot utillsima), Potato (Solanum tuberosum), Cocoyam (Colocasia esculenta), Three-leaved Yam (D. domenturum) and Aeriel Yam (Discorea bulbifera) were obtained from Ebonyi State and used for this work. The foods were mashed and modified by retrogradation. Proximate analysis and functional properties were carried on both retrograded and fresh (control) starch samples. Result of proximate analysis showed significant increase (p<0.05) for moisture content, dry matter and bulk density for retrograded samples against the controls. However, the reverse was the case for mineral ash, crude fibre, crude protein, swelling index and water absorption capacity. The results also showed that sample F (Yam) had the higher gelatinization temperature of 86°C, followed by Potato and Arial Yam (84ºC), Three-leaved Yam (80ºC), Cocoyam (72ºC) and then Cassava (69ºC). Key words: Retrogradation Gelatinization Starch Nutrients Amylose Amylopectin INTRODUCTION swelling, crystal or double helical melting and amylose leaching.

    Matrix Effect on Fat Crystallization in Laminated Bakery Products by Kristin Danielle Mattice A Thesis presented to The University of Guelph In partial fulfillment of requirements for the degree of Master of Science In Food Science Guelph, Ontario, Canada © Kristin Danielle Mattice, August, 2017 ABSTRACT Matrix Effect on Fat Crystallization in Laminated Bakery Products Kristin Danielle Mattice Advisor: University of Guelph, 2017 Dr. Alejandro G. Marangoni The impact of a croissant matrix on fat crystallization was determined by analyzing the polymorphism using powder x-ray diffraction (XRD), solid fat content (SFC) by pulsed nuclear magnetic resonance (p-NMR) and melting behaviour by differential scanning calorimetry (DSC). Roll-in shortenings of varying composition were used to prepare croissants. XRD revealed polymorphic conversion (from β' to the β form) occurs when fat is baked within the matrix, and the extent of conversion depends on the fat’s composition. In addition, the fat contained within a croissant will have a significantly lower SFC and a greater temperature is required for complete melting. The same fats were then baked in the presence of isolated croissant components (wheat starch, gelatinized wheat starch, gluten and a formed gluten network) and the cooled samples were analyzed using the same methods. Overall, the results suggested that changes in crystallization behaviour are caused by an interaction between fat and gelatinized wheat starch. ii ACKNOWLEDGEMENTS I would like to start by thanking my supervisor, Dr. Alejandro Marangoni, for all of his guidance over the past two years. He has been incredibly supportive and encouraging throughout this time, always pushing me to think, question and discuss.

Potato starch was modified using different concentrations of DSA (0, 1, 3, and 5%, v/v). The degree of substitution (DS) for the DSA-modified starch ranged from 0.0012 to 0.0055. The amylose leaching values of native and DSA-modified potato starch with different DS levels were in the range of 47.09-87.32%. The gel strength values of the DSA-modified starch were lower than those of native potato starch. Rapid Visco Analyzer data showed that peak, hot pasting, final and setback viscosities of the native starch decreased after DSA modification. Dynamic shear rheological tests, conducted at 4 °C, indicated that DSA-modified potato starch had weak gel-like behavior with the storage moduli (G’) higher than the loss moduli (G”) over most of the frequency ranges (0.63-63.8 rad·s-1). Keywords: potato starch; octenyl succinic anhydride; rheological property; pasting property; retrogradation. Practical Application: Higher stability of DSA-modified potato starch can better withstand freeze-thawing of frozen food. 1 Introduction Potato starch is a good texture stabilizer and regulator in Retrogradation is a general term for the recrystallization food; however, limitations like low shear stress resistance, thermal behavior of gelatinized starches upon cooling and storage, and resistance, thermal decomposition, and high retrogradation have is accompanied by gel hardening and the leakage of water from limited its use in some industrial food applications (Hong et al., the starch gel (Lian et al., 2014).
