Beschreibung

The discovery of resistant starch is considered one of the major developments in our understanding of the importance of carbohydrates for health in the past twenty years. Resistant starch, which is resistant to digestion and absorption in the human small intestine with complete or partial fermentation in the large intestine, is naturally present in foods. 

Resistant Starch: Sources, Applications and Health Benefits covers the intrinsic and extrinsic sources of resistant starch in foods, and compares different methods of measuring resistant starch and their strengths and limitations. Applications in different food categories are fully covered, with descriptions of how resistant starch performs in bakery, dairy, snack, breakfast cereals, pasta, noodles, confectionery, meat, processed food and beverage products.

Preface

Since the term ‘dietary fibre’ was first coined in 1953, it has undergone several transformations with respect to its definition, composition, analytical methodology and physiological effects. Its heterogeneous composition of naturally-occurring non-starch polysaccharides, lignin and associated substances has grown to include other synthetic or novel fibres, comprising digestion-resistant dextrins and resistant starches. Because of this diverse composition, analysts are often confronted with the challenge of accurately quantifying the level of total dietary fibre of food or beverage products. Dietary fibre is now less frequently associated with bulk or regularity and is discussed much more conspicuously with its role in attenuation of glycemic/insulinemic responses, blood cholesterol lowering, satiety effects, weight management, large bowel fermentation and changes in gut microbiota composition and metabolism in regard to their impact on the general health and well-being of consumers.

Consumer demand for fibre-rich foods and beverages in the United States, Europe and Asia-Pacific is rising due primarily to the preponderance of positive epidemiological and scientific data and also an increase in consumer awareness and support from dieticians and nutritionists. Ironically, however, many Americans on average consume only about 50–60% of their recommended daily intake of 25 g of fibre.

Resistant starch (RS), in particular, has captivated leading research scientists and prominent educators, and their investigations have been featured prominently in scientific literature on fibre. Many research activities on RS highlighted its structure, composition, functionality, in vitro and in vivo studies and performance in food and beverage products. RS has five types or classes and, therefore, it provides diverse materials for research investigators. These, together with the commercial significance of RS, account for the abundance of published articles and inventions in the scientific and patent literature. Commercial sources of RS number around 30 – a substantial increase since the first RS product was introduced to the market in 1993.

The idea of writing this book was developed from the Carbohydrate Division Symposium on resistant starch and health during the 2009 IFT Annual Meeting in Anaheim, California. The symposium attracted speakers who are leading researchers and scientists from the academia and the food industry. In order to capture the important developments in RS, with emphasis on sources, applications and health benefits, the editors embarked on a project to write this book using the symposium papers plus the contribution of invited scientists and academic professionals who excel in this important area of RS.

There are 15 chapters in the book, covering various topics on RS, such as its biosynthesis, types or classes, slowly digestible starch, methodology for measurement and food applications, and also the physiological effects of RS, primarily in the area of glycemic/insulinemic control, appetite/satiety, gut microbiota metabolism and large bowel health. This book caters to a wide audience and can be a valuable resource for students, professors, research scientists, product developers and other food industry professionals, as they investigate the ever-growing area of RS and its diverse properties, numerous food and beverage applications, commercial significance and physiological effects.

Starch Biosynthesis in Relation to Resistant Starch

Geetika Ahuja, Sarita Jaiswal and Ravindra N. Chibbar

1.1 Introduction

1.1.1 Starch components

Starch is present in amyloplasts as semi-crystalline intracellular water-insoluble granules, with alternating crystalline and amorphous layers. Starch is a glucan homopolymer composed of one-quarter amylose (molecular mass 105–106 Da) and three-quarters amylopectin (molecular mass 107–109 Da), along with traces of lipids (0.1–1.0%) and proteins (0.05–0.5%). Amylose is essentially a linear glucan polymer, composed of α-1,4 linked glucose residues with a degree of polymerization (dp) ranging between 800 (in maize and wheat) to more than 4500 (in potato) with sparse branching (approximately one branch per 1000 residues) (Morrison & Karkalas, 1990; Alexander, 1995). Structural and functional aspects of these glucan polymers affect starch functionality and its end use.

Amylose chains are capable of forming single or double helices. On the basis of orientation of its fibres in X-ray diffraction studies, amylose can be divided into A- and B-type allomorphs (Galliard et al., 1987). In B-type allomorph, six double helices are packed in an anti-parallel hexagonal mode surrounding the central water channel (36 H2O per unit cell). In A-type, the central water channel is replaced by another double helix, making the structure more compact. In this allomorph, only eight molecules of water per unit cell are inserted between the double helices (Galliard ., 1987).
