Canola Proteins and its Functionality in Food Systems investigates the molecular interactions involved in gelation and emulsification of CPI-hydrocolloid systems. Oilseed proteins contribute useful functionality to food systems. Knowledge of the molecular interactions between plant proteins such as commercial canola protein isolate (CPI) and other components allows the manipulation of physical and textural properties of mixed biopolymers by adjusting macromolecular interactions. Protein-polysaccharide interactions give a realistic indication of plant proteins behavior in food systems and provides useful information for the development of canola protein products. This book provides the details of functional and physiochemical properties of CPI-hydrocolloids , the type and degree of their interactions, and optimum conditions for gelation and emulsification. Presents characteristics of gels of CPI-hydrocolloid mixtures using dynamic rheology and microscopy Identifies optimized conditions for specific functional properties such as network and emulsion formation Explores electrostatic complexing and synergistic interactions that contribute to the formation of strong, elastic CPI-hydrocolloid gels Provides findings on improvements in the emulsifying properties and surface hydrophobicity of CPI-hydrocolloid mixtures when compared to CPI alone

Oilseed proteins contribute useful functionality to food systems. Knowledge of the molecular interactions between plant proteins such as commercial canola protein isolate (CPI) and hydrocolloids such as K-carrageenan (k-CAR) and guar gum will allow the manipulation of physical and textural properties of mixed biopolymers by adjusting the interaction in a desirable way. This research investigates the molecular interactions involved in gelation and emulsification of these CPI-hydrocolloid systems. The objectives were to: a) determine the functional and physicochemical properties of CPI-k-CAR and CPI-guar gum mixtures; b) determine the type and degree of interactions between CPI and k-CAR or guar gum based on protein conformational changes assessed by differential scanning calorimetry, fluorescence spectroscopy and microscopy; and c) establish optimum conditions for gelation and emulsification of these systems. Gelling characteristics and emulsifying properties were evaluated using dynamic rheology and spectroturbidimetry, respectively. This study has 1) characterized the gel properties of CPI-k-CAR and CPI-guar gum mixtures using dynamic rheology and microscopy; 2) optimized conditions for specific functional properties such as network and emulsion formation. Optimum conditions for gelation of CPI-k-CAR mixtures were pH 6, 3% (w/v) k-CAR, 0.05 M NaCl, 15% (w/v) CPI; whereas those for CPI-guar gum mixtures were pH 10, 1.5% (w/v) guar gum, 0.05 M NaCl, 20% (w/v) CPI. Electrostatic complexing and synergistic interaction contributed to the formation of strong and elastic CPI-k-CAR gels. The synergistic behaviour was supported by the microstructural data of gel networks. Furthermore, optimum conditions for CPI-k-CAR-stabilized emulsions were pH 6, 1% (w/v) k-CAR, 0.25 M NaCl, 10% (w/v) CPI; whereas those for CPI-guar gum-stabilized emulsions were pH 10, 3% (w/v) guar gum, 0.25 M NaCl, 10% (w/v) CPI; 3) confirmed that hydrophobic interactions, hydrogen bonding and disulfide linkages are the main molecular forces involved in the formation and stabilization of CPI-k-CAR and CPI-guar gum gels and emulsions; 4) reported improvements in the emulsifying properties and surface hydrophobicity of these CPI-hydrocolloid mixtures, when compared to CPI alone. Protein-polysaccharide interactions give a realistic indication of plant proteins behaviour in food systems and provide useful information for the development of functional canola protein products.

The book is devoted to expanding current views on the phenomena of protein functionality in food systems. Protein functionalities in foods have been the object ofextensive research over the last thirty to forty years and significant progress has been made in understanding the mechanism and factors influencing the functionality of proteins. The functionality of proteins is one of the fastest developing fields in the studies of protein utilization in foods. Currently, a broad spectrum of data related to protein functionality in food systems has been collected, however, much more needs to be known. In this volume, the most important functional properties offood proteins are presented: Protein solubility, water holding capacity and fat binding, emulsifying, foaming, and gelling properties as affected by protein source, environmental factors (pH, temperature, ionic strength) and protein concentration; Relationships between protein conformation, physicochemical properties, and functional properties; Protein functional properties as influenced by various food processing conditions, particularly heat treatment, dehydration, freezing and storage when frozen, extraction and other processes; Effects ofprotein modification on the enhancementofprotein functionality; Utilization ofvarious proteins in improving functional properties in food systems. Those aspects of protein functionality are presented which the author believes to be interesting and most important for protein utilization in food systems. The book is recommended to students and food scientists engaged in food protein research and food industry research, and development scientists.

Food proteins are of great interest, not only because of their nutritional importance and their functionality in foods, but also for their detrimental effects. Although proteins from milk, meats (including fish and poultry), eggs, cereals, legumes, and oilseeds have been the traditional sources of protein in the human diet, potentially any proteins from a biological source could serve as a food protein. The primary role of protein in the diet is to provide the building materials for the synthesis of muscle and other tissues, and they play a critical role in many biological processes. They are also responsible for food texture, color, and flavor. Today, food proteins are extracted, modified, and incorporated into processed foods to impart specific functional properties. They can also have adverse effects in the diet: proteins, such as walnuts, pecans, almonds, and cashews, soybean, wheat, milk, egg, crustacean, and fish proteins can be powerful allergens for some people. Applied Food Protein Chemistry is an applied reference which reviews the properties of food proteins and provides in-depth information on important plant and animal proteins consumed around the world. The book is grouped into three sections: (1) overview of food proteins, (2) plant proteins, and (3) animal proteins. Each chapter discusses world production, distribution, utilization, physicochemical properties, and the functional properties of each protein, as well as its food applications. The authors for each of the chapters are carefully selected experts in the field. This book will be a valuable reference tool for those who work on food proteins. It will also be an important text on applied food protein chemistry for upper-level students and graduate students of food science programs.

Engineering Plant-Based Food Systems provides a comprehensive, in-depth understanding on the technologies used to create quality plant-based foods. This title helps researchers and food processors gain an understanding of the diverse aspects of plant-based foods, with a focus to meet the current consumers' demand of alternatives to animal products. This is a one-stop source that provides maximum information related to plant-based foods to food science researchers, food engineers and food processing/manufacturers. This book will enhance their understanding of plant-based protein sources, their application, product manufacturing, and bioavailability. In recent years, the emphasis on minimizing environmental footprints (climate change, greenhouse gas emissions, deforestation, and loss of biodiversity) and human health issues related to animal source food intakes has shifted the attention of researchers, dietitians and health professionals from animal-based diets to diets rich in plant-based foods (legumes, nuts, seeds). Explores the plant sources available for extraction of proteins, the various extraction methods and the quality and functionality of the extracted proteins Describes existing plant-based foods such as beverages, yogurts, spreads, fermented foods and meats Provides information related to various plant based functional components such as polyphenols, phytosterols, aromatics and essential oils, etc.
