Delivery and Controlled Release of Bioactives in Foods and Nutraceuticals


Book Description

Active ingredients in foods must remain fully functional for as long as necessary and be transported and discharged appropriately to have the desired nutritional effect. Delivery and controlled release systems are an essential way to achieve these aims. This important book reviews how to optimise these systems to maximise the health-promoting properties of food products.Opening chapters review factors affecting nutrient bioavailability and methods to test delivery system efficacy. Part two addresses materials used and specific techniques for delivery and release. The benefits and drawbacks of structured lipids, micro- and nano-emulsions, food-protein-derived materials, complexes and conjugates of biopolymers, and starch as an encapsulation material for delivery of functional food ingredients, are all considered. Part three discusses the delivery and controlled release of particular nutraceuticals such as antioxidants and vitamins, folic acid, probiotics, fish oils and proteins. Part four covers regulatory issues and future trends in bioactives and nutraceuticals.Edited by a leading expert in the field, Delivery and controlled release of bioactives in foods and nutraceuticals is a valuable reference for those working in the food industry and particularly those developing nutraceuticals. - Reviews techniques to optimise the delivery and release of bioactives in food - Discusses the factors that affect nutrient bioavailability and methods to test delivery system efficacy - Addresses materials used and specific techniques for delivery and release




Nutrient Delivery


Book Description

Nutrient Delivery: Nanotechnology in the Agri-Food Industry, Volume Five, discusses the fabrication, merits, demerits, applications, and bioavailability enhancement mechanisms of various nanodelivery systems. Recent developments in various nanodelivery systems are also highlighted. Volume 5 contains twenty chapters, prepared by outstanding international researchers from Argentina, Brazil, Canada, China, Croatia, India, Iran, Ireland, México, Pakistan, Portugal, Serbia, Sri Lanka, and the United States. In recent years, the delivery of micronutrients at nanoscale has been widely studied as these systems have the potential to improve bioavailability, enable controlled release and enhance stability of food bioactives to a greater extent. The nanodelivery systems typically consist of the food bioactive compound encapsulated and stabilized in food grade ingredients such as lipids, proteins or polysaccharides with diameters ranging from 10 nm to 1000 nm. Among these, the lipid based delivery systems such as nanoemulsions, solid lipid nanoparticles, nanoliposomes and micelles are widely studied for the delivery of lipophilic bioactive compounds. These delivery vehicles improve the solubility, permeability, stability and bioavailability of the lipophilic compounds thereby enhancing their potential for oral delivery and functional food development. On the other hand, the hydrophilic bioactives are delivered through protein, polysaccharide or biopolymer based colloidal nanosystems such as hydrogels, nanogels and polymer nanoparticles. The major concern other than solubility is the intestinal permeability of the micronutrients. For instance, the delivery system for compounds with poor intestinal permeability and low solubility need to be carefully designed using suitable lipids and surfactants. - Offers updated material for undergraduate and postgraduate students in food science, biotechnology, and related engineering fields - Provides a valuable resource of recent scientific progress, along with most known applications of nanomaterials in the food industry for researchers, engineers, and academics - Includes novel opportunities and ideas for developing or improving technologies in the food industry

Encapsulation Technologies for Active Food Ingredients and Food Processing


Book Description

Consumers prefer food products that are tasty, healthy, and convenient. Encapsulation is an important way to meet these demands by delivering food ingredients at the right time and right place. For example, encapsulates may allow flavor retention, mask bad tasting or bad smelling components, stabilize food ingredients, and increase their bioavailability. Encapsulation may also be used to immobilize cells or enzymes in the production of food materials or products, such as fermentation or metabolite production. This book provides a detailed overview of the encapsulation technologies available for use in food products, food processing, and food production. The book aims to inform those who work in academia or R&D about both the delivery of food compounds via encapsulation and food processing using immobilized cells or enzymes. The structure of the book is according to the use of encapsulates for a specific application. Emphasis is placed on strategy, since encapsulation technologies may change. Most chapters include application possibilities of the encapsulation technologies in specific food products or processes. The first part of the book reviews general technologies, food-grade materials, and characterization methods for encapsulates. The second part discusses encapsulates of active ingredients (e.g., aroma, fish oil, minerals, vitamins, peptides, proteins, probiotics) for specific food applications. The last part describes immobilization technologies of cells and enzymes for use within food fermentation processes (e.g., beer, wine, dairy, meat), and food production (e.g., sugar conversion, production of organic acids or amino acids, hydrolysis of triglycerides). Edited by two leading experts in the field, Encapsulation Technologies for Food Active Ingredients and Food Processing will be a valuable reference source for those working in the academia or food industry. The editors work in both industry or academia, and they have brought together in this book contributions from both fields.
