This book was released on 2000 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relatively little is known about the quantitative effects of fat on the biochemistry, rheology and sensory properties of Cheddar cheese. However, the limited information available indicates that reduced fat Cheddar cheeses have a low consumer acceptance due to texture and flavour defects. The objectives of the current study were to (a) evaluate the composition, biochemical and sensory properties of commercial Cheddar cheeses of different fat contents available in Ireland and UK (b) determine the effect of incremental fat reduction on Cheddar cheese composition, yield and age-related changes in microbiology, proteolysis and rheology (c) evaluate the effect of variations in cheesemaking parameters, including milk pretreatments, and starter culture adjuncts on the chemical, rheological and sensory properties of half fat Cheddar cheese (~ 17.5 % w/w). Commercial reduced fat Cheddar cheeses exhibited marked variation in the contents of moisture, moisture in non-fat substance and proteolysis, as measured by the levels of pH. 4.6 soluble N and free amino acids. Fat content of commercial Cheddar cheeses did not significantly influence proteolysis but significantly influenced the intensities of the flavour attributes buttery, creaminess and caramel. Reduction of the fat content of experimental Cheddar cheeses in the range 33 to 6 % (w/w) resulted in increases in the contents of moisture, moisture in non-fat substance and protein, increases in firmness and fracture stress, and decreases in the level of primary proteolysis. Starter cell counts and the rate of decline of starter lactococci during ripening was little influenced by fat content However, the rate of growth of non-starter lactic acid bacteria during ripening increased with increasing fat content. The texture of half fat Cheddar cheese, as measured instrumentally, was improved by increasing pasteurisation temperature, addition of a whey protein based preparation 'Dairy LoÞ, to the cheesemilk, increasing set-to-cut time, increasing curd milling pH, and increasing ripening temperature from 7 to 120C and/or use of commercially available starter culture blends and bacterial adjunct containing Lactobacillus helveticus.

This book was released on 2013-11-11 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the art of making cheese can be traced to prehistoric times, it has continued to evolve as modern civilization progressed. The advent of new technologies and instrumentation has brought exponential growth in the understanding of cheese components and their function. Even more recently, the evolution of cheesemaking has accelerated, driven by economic factors such as the establishment of the European Economic Community, the changing diet of developed countries, and the environmental and economic concerns associated with whey disposal. Molecular biology has revolutionized the development of starter and adjunct cultures as well as rennets, and genetics will make it possible to maintain ideal milk components for cheesemaking. The ability to accelerate traditional ripening procedures has altered the production of certain cheeses, and the emphasis on decreasing the intake of dietary fat, especially in the United States, has prompted the development of technology for producing low-fat cheeses with traditional texture and flavor. In assembling a distinguished group of participants for the symposium, "Chemistry of the Structure/Function Relationships in Cheese," we hoped to review the interplay of these trends and forecast the direction of future research. Contributors evaluated the current status of cheesemaking and highlighted the information that will be essential for new developments. They also focused the attention of agricultural and food chemists on the opportunities in cheese research and the potential contributions they might make to the future of cheese, a most valuable food product. We are indebted to Dr. Patrick Fox, Dr. Mark Johnson, Dr. Milos Kalab, Dr.

This book was released on 2011 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-fat cheese faces great challenges associated with its texture being hard and rubbery, desirable flavors being missing, color being undesirably intense and translucent appearing, and melting being improper. In an effort of improving the quality of low-fat cheeses, several strategies have been tried to accomplish three major objectives, 1) improving the melting and baking properties of low-fat Mozzarella cheese, 2) improving the color of low-fat Cheddar cheese, and 3) investigating the feasibilities of enriching low-fat Cheddar cheese with dietary fibers. For objective 1, 4 batches of low-fat Mozzarella cheese with target fat of 6.0%, 4.5%, 3.0%, and 1.5% were made using a stirred curd method, comminuted in a bowl chopper and mixed with different levels of melted butter (0.0, 1.5, 3.0, and 4.5% (wt/wt), respectively) before pressing. This would made the cheese that had increased free oil, increased melting, and improved baking as the level of added butter increased. The added butterfat was present as free fat along the curd particle junctions as shown by laser scanning confocal microscopy while the fat droplets originating from the milk were distributed within the protein matrix of the cheese. In objective 2, consumer tests and flavor profile analysis were performed on 4 commercial brands of full-fat Cheddar cheese and 9 low-fat Cheddar cheeses manufactured at Utah State University with different colors. Low-fat cheeses were rated different (P
