Book excerpt: Baking of bread at 300. 400 and 500°C for 150s, 70s, and 35s, respectively, led to a marked decrease in the percentage of total proteins present as albumins, globulins, gliadins. and glutenins with a corresponding increase in the insoluble residue fraction. Baking at 500°C caused a greater increase in the insoluble residue fraction than did baking at the lower temperatures. This was accompanied by the formation of disulfide linkages between the constituent polypeptides. Selective solubilization of the bread and dough samples in 1% sodium dodecyl sulfate (SDS), 2% 2-Mercaptoethanol (2-ME), and 1% SDS + 27c 2-ME showed that both disulfide bond formation and hydrophobic interactions were involved in the aggregation of wheat proteins during baking. This aggregation caused an increase in their molecular weight and resulted in a decrease in protein solubility. Sodium dodecyl sulfate-polyacrylamide gelectrophoresis (SDS-PAGE) patterns revealed that fragmentation of proteins also occurred during baking with both the high molecular weight (HMW) and low molecular weight (LMW) proteins breaking then reassociating to form new/different HMW and LMW polypeptides. The glutenins and soluble proteins were the main fractions which experienced major changes during baking, with glutenins being the most sensitive to changes in baking temperature. The high baking temperature of Arabic bread did not affect the in vitro protein digestibility of the product as compared to that of the dough.

Available in PDF, EPUB and Kindle. Book excerpt: Three wheat (Triticum aestivum L.) flours of good (A), medium (B) and poor (C> baking quality were used in studying the effect of protein quality in the baking of Arabic bread. Flours A and C were fractionated into: starch, lipid, solubles and gluten proteins. Glutens A and C were further fractionated into gliadias and glulenins by successive extraction with dilute HCI. Sodium Dodecylsulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE) and protein analysis indicated that gluten A has a higher gliadin/glutcnin ratio than gluten C. Upon reconstituiion of flours A and C with their gliadins and glutenins being interchanged, it was observed, using sensory evaluation, that exchange of gliadins did not exert an effect, whereas, exchange of glutenins was detrimental to the baking quality of both flours A and C. Addition of gliadias and glutenins from Hours A and C, at the rate of 1 % and 2%, to flour B had different effects on the quality. Increasing the gliadins proportion yielded loaves with better quality than when increasing the glutenin proportion. It is concluded that the type of glutenin and the gliadin/glutenin ratio are the main determinants of the baking quality of flours intended for Arabic breadmaking.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A kitchen classic for over 35 years, and hailed by Time magazine as "a minor masterpiece" when it first appeared in 1984, On Food and Cooking is the bible which food lovers and professional chefs worldwide turn to for an understanding of where our foods come from, what exactly they're made of, and how cooking transforms them into something new and delicious. For its twentieth anniversary, Harold McGee prepared a new, fully revised and updated edition of On Food and Cooking. He has rewritten the text almost completely, expanded it by two-thirds, and commissioned more than 100 new illustrations. As compulsively readable and engaging as ever, the new On Food and Cooking provides countless eye-opening insights into food, its preparation, and its enjoyment. On Food and Cooking pioneered the translation of technical food science into cook-friendly kitchen science and helped birth the inventive culinary movement known as "molecular gastronomy." Though other books have been written about kitchen science, On Food and Cooking remains unmatched in the accuracy, clarity, and thoroughness of its explanations, and the intriguing way in which it blends science with the historical evolution of foods and cooking techniques. Among the major themes addressed throughout the new edition are: · Traditional and modern methods of food production and their influences on food quality · The great diversity of methods by which people in different places and times have prepared the same ingredients · Tips for selecting the best ingredients and preparing them successfully · The particular substances that give foods their flavors, and that give us pleasure · Our evolving knowledge of the health benefits and risks of foods On Food and Cooking is an invaluable and monumental compendium of basic information about ingredients, cooking methods, and the pleasures of eating. It will delight and fascinate anyone who has ever cooked, savored, or wondered about food.
