Taylor, Janet; Anyango, Joseph Ochieng; Potgieter, Marnie; Kallmeyer, Karlien; Naidoo, Vinny; Pepper, Michael Sean; Taylor, J.R.N. (John Reginald Nuttall) (Wiley, 2015-08)Kafirin, the sorghum prolamin protein, like its maize homologue zein, can be made into micropatticles and films and potentially used as a biomaterial. Zein has good bio- and cytocompatibility. Kafirin could be advantageous ...

Baloyi, Julia Thandikile; Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (Wiley, 2023-07)BACKGROUND AND OBJECTIVE : Quality protein maize (QPM) has abundant γ-zein, which crosslinks itself and other zeins through disulfide bonding. The work aims to develop zein bioplastics with better functionality by using ...
-
Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall); Kini, Felix (American Association of Cereal Chemists, 2012-07)Under-nutrition is a key underlying cause of the 10 million child deaths each year—most of which are preventable and most of which occur in poor countries. The major direct causes of under-nutrition in poor developing ...
-
Oguntoyinbo, Segun I.; Taylor, J.R.N. (John Reginald Nuttall); Taylor, Janet (Elsevier, 2018-09)Kafirin and zein could be used in making wheat-free leavened dough-based products if their functionality can be modified to more closely resemble gluten. Recently, stable viscoelastic masses were produced from isolated ...
-
Taylor, Janet; Anyango, Joseph Ochieng; Muhiwa, Peter J.; Oguntoyinbo, Segun I.; Taylor, J.R.N. (John Reginald Nuttall) (Elsevier, 2018-04-15)Zeins of differing sub-class composition much more readily formed visco-elastic masses in water or acetic acid solutions than equivalent kafirin preparations. Visco-elastic masses could be formed from both zein and kafirin ...
-
Taylor, Janet; Anyango, Joseph Ochieng; Taylor, J.R.N. (John Reginald Nuttall) (American Association of Cereal Chemists, 2013-07)Despite much research, there are very few commercial prolamin bio-plastics. The major reason, apart from their high cost, is that they have inferior functional properties compared to synthetic polymer plastics. This is ...
-
Taylor, J.R.N. (John Reginald Nuttall); Taylor, Janet (Wiley, 2023-05)BACKGROUND AND OBJECTIVES : There is considerable interest in kafirin, sorghum prolamin, as a bioplastic material because it apparently produces bioplastics with superior functional properties. This review evaluates the ...
-
Buchner, Sonya; Kinnear, Marise; Crouch, Ian J.; Taylor, Janet; Minnaar, Amanda (Wiley, 2011-12)BACKGROUND: Pears are exported in large quantities from South Africa resulting in large revenues. Minimisation of quality losses once the fruit has reached the export destination is as important as following strict export ...

Da Silva, Laura S.; Jung, Rudolf; Zhao, Zuo-yo; Glassman, Kimberly; Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (Elsevier, 2011-07)To improve sorghum grain protein nutritional quality, improved sorghum lines were transformed to suppress the synthesis of different kafirin sub-classes, or backcrossed into transgenic lines with improved protein quality. ...
-
Muhiwa, Peter J.; Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (American Association of Cereal Chemists, 2017-07)The high cost of kafirin and zein restricts their use for bioplastic and food applications. Effective, simple, and rapid kafirin/zein isolation processes are required. Here a percolation-type aqueous ethanol solvent ...
-
Elhassan, Mohammed S.M.; Oguntoyinbo, Segun I.; Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (Elsevier, 2018-01)Stable viscoelastic masses have been formed from kafirin in a mainly aqueous system. Kafirin was dissolved in glacial acetic acid (GAA) and simple coacervation was performed by rapid addition of 15 °C water under low shear. ...
-
King, Bianca L.; Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (Elsevier, 2016-09)Only predominantly α-type zein (commercial zein) has been shown to form a viscoelastic dough. In maize zein comprises α-, β-, γ- and δ-zein (total zein). Because glacial acetic acid can fully solubilise zein, its effect ...
-
Taylor, J.R.N. (John Reginald Nuttall); Taylor, Janet; Campanella, Osvaldo H.; Hamaker, Bruce R. (Elsevier, 2016-01)The dough functionality of the storage proteins in “gluten-free” grains has been studied for almost 25 years. Zein, maize prolamin, when isolated as a-zein can form a wheat gluten-like visco-elastic dough when mixed with ...
-
Taylor, Janet; Muller, M.; Minnaar, Amanda (Wageningen Academic Publishers, 2016-04)Coating comprising the plant protein, kafirin, propylene glycol (PG) and glucono-delta-lactone (GDL) have been shown to extend the quality of ‘Packham’s Triumph’ pears. In this study, both of these coating treatments ...
-
Anyango, Joseph Ochieng; Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (American Chemical Society, 2011)Improvement in the water stability and other related functional properties of thin (<50 µm) karirin protein films was investigated. Thin conventional kafirin films and kafirin microparticle films were prepared by casting ...
-
Sly, Alexandra Claire; Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (Elsevier, 2014-07)The replacement of gluten in dough products poses a major challenge. Preparing zein doughs in dilute acetic acid and lactic acid, such as produced during sourdough fermentation, was investigated. Increasing acid ...

Links, Malory R.; Taylor, J.R.N. (John Reginald Nuttall); Kruger, Marlena C.; Naidoo, Vinny; Taylor, Janet (Elsevier, 2016-01)In vitro analysis has indicated that sorghum condensed tannins (SCT) survived simulated gastric digestion and inhibited digestive amylases when encapsulated in sorghum kafirin protein microparticles (SCT-KEMS). This study ...
-
Taylor, Janet; Taylor, J.R.N. (John Reginald Nuttall) (Wiley, 2018-08)Kafirin, the sorghum prolamin, is the most hydrophobic of the prolamins, and forms disulfide cross‐links because of its high cysteine content. It is noted for its slow digestibility but does not trigger any adverse response ...
-
Ncube, Mphokuhle B.; Taylor, Janet; Bean, Scott R.; Ioerger, Brian P.; Taylor, J.R.N. (John Reginald Nuttall) (Elsevier, 2022-03)Kafirin, sorghum prolamin, was investigated as a coprotein for zein as visco-elastic masses and in starch-based model doughs. Regular kafirin and kafirins from waxy and high protein digestibility (HD) sorghum crosses were ...
-
Taylor, J.R.N. (John Reginald Nuttall); Johnson, Stuart K.; Taylor, Janet; Njila, Sharon; Jackaman, Connie (Elsevier, 2016-07)To improve the rheological properties of zein doughs, a-type zein and zein-starch doughs were prepared with the oxidising agents, hydrogen peroxide and peroxidase, which strengthen gluten-based doughs by cross-linking. ...
