Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

Starch accumulation in hulless barley during grain filling

Botanical Studies, 2017
Background Starch consists of two types of molecules: amylose and amylopectin. The objective of this study was increase understanding about mechanisms related to starch accumulation in hulless barley (Hordeum vulgare L.) grain by measuring temporal ...

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =

Novel cassava starches with low and high amylose contents: Structural and macro-molecular characterization in comparison with other commercial sources [PDF]

, 2012
Cassava (Manihot esculenta Crantz) is one of the most important sources of commercial production of starch along with potato, maize and wheat particularly for tropical and subtropical regions of the world.

Metabolic effects of diets differing in glycaemic index depend on age and endogenous GIP [PDF]

, 2009
Aims/hypothesis High- vs low-glycaemic index (GI) diets unfavourably affect body fat mass and metabolic markers in rodents. Different effects of these diets could be age-dependent, as well as mediated, in part, by carbohydrate-induced stimulation of ...

A parameterized model of amylopectin synthesis provides key insights into the synthesis of granular starch. [PDF]

PLoS ONE, 2013
A core set of genes involved in starch synthesis has been defined by genetic studies, but the complexity of starch biosynthesis has frustrated attempts to elucidate the precise functional roles of the enzymes encoded.

Infused Tiger Nut and Almond Nut Crunchy Snacks Enhanced the Nutritional Value and Antioxidant Activity in High‐Fat Diet Fed Rat

Food Chemistry International, EarlyView.
Crunches were produced from formulations of almond nuts and tiger nuts (AN–TN) for the plausible management of commodity disease of obese condition. The produced AN–TN crunches showed high consumers acceptability, phenolic, and amylopectin contents. In addition, formulated percentages of AN–TN crunches when fed to high‐fat diet (HFD) fed rats led to ...

Production of amylopectin and high-amylose starch in separate potato genotypes [PDF]

, 2004
Starch is one of the most important processed products from agriculture. Two main outlets can be identified; starch is either enzymatically processed for the production of sweeteners and as raw material for fermentation or channelled to various ...

Nutritional, Functional, and Anti‐Hypercholesterolemic Properties of Sourdough Breads From Unripe Plantain, Tiger Nut, and Fenugreek Flours

Food Chemistry International, EarlyView.
Composite sourdough breads were developed from blends of unripe plantain, tiger nut, and fenugreek flours. Optimized formulations improved pasting stability and enhanced texture, producing softer more elastic crumbs. The enriched breads contained higher dietary fiber and bioactive compounds, and significantly reduced serum cholesterol markers ...
