This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Effects of enzymatic modification of starch, proteins and pentosans on dough and tortilla properties were determined to establish the role of these wheat components in tortilla staling. Starch, protein and pentosans were respectively modified with a-amylase, protease and transglutaminase (TG), and xylanase. Tortillas were stored at 22oC and evaluated for at least three weeks. Amylase improved shelf-stability of tortillas, produced a significant amount of dextrins and sugars, retarded decrease in amylose solubility, and weakened starch granules. However, control and treated tortillas had similar degrees of amylopectin crystallinity. Staling of tortillas appears to involve starch that reassociates into an amorphous structure. Micrographs of control dough had thin protein strands forming a continuous matrix. Protease-treated dough had pieces of proteins in place of the continuous matrix, while TG-treated dough had thicker protein strands that were heterogeneously distributed. Both treatments resulted in shorter shelf-stability of tortillas. The organization of protein in dough is important for dough structure and appears to impact tortilla flexibility. Protein solubility and SDS-PAGE results did not differentiate control and treated dough or tortillas. The fractions or molecular weight distribution are not significant determinants of protein functionality. Tertiary and quaternary protein structures of gluten may be more related to tortilla shelf-stability. The 75 ppm xylanase treatment resulted in weaker tortilla structure and significantly higher amounts of low molecular weight saccharides and sugars. Control and the 25 ppm treatment sample had a similar shelf-stability and texture profile. Pentosans may affect staling indirectly through the effect on gluten development. Fresh tortillas have amylopectin in an amorphous state, while amylose is mostly retrograded. The gluten matrix provides additional structure and flexibility to the tortilla. Pentosans may or may not be attached to the gluten network. Upon storage, amylopectin retrogrades and recrystallizes, firming the starch granules, resulting in firmer tortillas. Starch hydrolysis decreased the rigid structure and plasticized polymers during storage. It also reduced the restriction imposed by retrograded starch on gluten and allowed it more flexibility. Thus, the flexibility of tortillas results from the combined functionalities of amylose gel, amylopectin solidifying the starch granules during storage, and the changed functionality of gluten after baking.

Download or read book Flour and Breads and their Fortification in Health and Disease Prevention written by Victor R Preedy and published by Academic Press. This book was released on 2011-02-17 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bread and flour-based foods are an important part of the diet for millions of people worldwide. Their complex nature provides energy, protein, minerals and many other macro- and micronutrients. However, consideration must be taken of three major aspects related to flour and bread. The first is that not all cultures consume bread made from wheat flour. There are literally dozens of flour types, each with their distinctive heritage, cultural roles and nutritive contents. Second, not all flours are used to make leavened bread in the traditional (i.e., Western) loaf form. There are many different ways that flours are used in the production of staple foods. Third, flour and breads provide a suitable means for fortification: either to add components that are removed in the milling and purification process or to add components that will increase palatability or promote health and reduce disease per se. Flour and Breads and their Fortification in Health and Disease Prevention provides a single-volume reference to the healthful benefits of a variety of flours and flour products, and guides the reader in identifying options and opportunities for improving health through flour and fortified flour products. - Examines those flour and bread related agents that affect metabolism and other health-related conditions - Explores the impact of compositional differences between flours, including differences based on country of origin and processing technique - Includes methods for analysis of flours and bread-related compounds in other foods

This book was released on 2012-12-06 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume results from the Eighth Basic Symposium held by the Institute of Food Technologists in Anaheim, California on June 8-9, 1984. The theme of the symposium was "Chemical Changes in Food during Processing." The speakers included a mix of individuals from academic institu tions, governmental agencies, and the food industry. Twenty speakers discussed topics ranging from the basic chemistry relating to food constituents to the more applied aspects of chemical changes in food components during food processing. It was the intent of the organizers to bring together a group of speakers who could address the chemistry of changes in food compo nents during processing from a mechanistic point of view. As a con sequence, the proceedings of this symposium emphasize the basic chemistry of changes in food constituents from a generic perspective which is intended to provide the reader with a background to address more specific problems that may arise.

Download or read book Gluten Free Food Science and Technology written by Eimear Gallagher and published by John Wiley & Sons. This book was released on 2009-09-08 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coeliac disease (CD) and other allergic reactions/intolerances to gluten are on the rise, largely due to improved diagnostic procedures and changes in eating habits. The worldwide incidence of coeliac disease has been predicted to increase by a factor of ten over the next number of years, and this has resulted in a growing market for high quality gluten-free cereal products. However, the removal of gluten presents major problems for bakers. Currently, many gluten-free products on the market are of low quality and short shelf life, exhibiting poor mouthfeel and flavour. This challenge to the cereal technologist and baker alike has led to the search for alternatives to gluten in the manufacture of gluten-free bakery products. This volume provides an overview for the food industry of issues related to the increasing prevalence of coeliac disease and gluten intolerance. The properties of gluten are discussed in relation to its classification and important functional characteristics, and the nutritional value of gluten-free products is also addressed. The book examines the diversity of ingredients that can be used to replace gluten and how the ingredient combinations and subsequent rheological and manufacturing properties of a range of gluten-free products, e.g. doughs, breads, biscuits and beer may be manipulated. Recommendations are given regarding the most suitable ingredients for different gluten-free products. The book is directed at ingredient manufacturers, bakers, cereal scientists and coeliac associations and societies. It will also be of interest to academic food science departments for assisting with undergraduate studies and postgraduate research.

Download or read book Technology of Breadmaking written by Stanley P. Cauvain and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not another book on breadmaking! A forgiveable reaction given the length of time over which bread has been made and the number of texts which have been written about the subject. To study breadmaking is to realize that, like many other food processes, it is constantly changing as processing methodologies become increasingly more sophisticated, yet at the same time we realize that we are dealing with a food stuff, the forms of which are very traditional. We can, for example, look at ancient illustrations of breads in manuscripts and paintings and recognize prod ucts which we still make today. This contrast of ancient and modern embodied in a single processed foodstuff is part of what makes bread such a unique subject for study. We cannot, for example, say the same for a can of baked beans! Another aspect of the uniqueness of breadmaking lies in the requirement for a thorough understanding of the link between raw materials and processing meth ods in order to make an edible product. This is mainly true because of the special properties of wheat proteins, aspects of which are explored in most of the chapters of this book. Wheat is a product of the natural environment, and while breeding and farming practices can modify aspects of wheat quality, we millers and bakers still have to respond to the strong influences of the environment.
