Available in PDF, EPUB and Kindle. Book excerpt: Milk is an important food commodity and a very versatile food product that is often further processed into a variety of different dairy products. The dairy industry has long recognized the importance of using sensory analysis in order to provide consumers with consistent high quality dairy products. By using descriptive sensory analysis in conjunction with instrumental analysis, it is possible to identify compounds responsible for sensory perception of key flavors, anchor and define new sensory terms, study flavor formation throughout processing, and identify sources of off-flavors. This approach provides a framework for understanding and controlling flavor development. The main objective of this research was to characterize the flavor of Cheddar cheese, Chevre-style goat cheese, skim and whole milk powders during storage, and dried whey proteins by integrating the use of descriptive sensory analysis and instrumental volatile analysis. Four different flavor lexicons were utilized/developed in order to characterize flavors in these products. Some flavors, such as cooked/milky were present in all dairy products, while other flavors were identified only in certain products. There were ninety-three aroma active compounds identified in these products, with nineteen being found in all products. The main flavor reactions in these dairy products were proteolysis, lipolysis, and glycolysis. The secondary objective of this research was to advance our understanding of flavor formation in dairy products using instrumental and sensory techniques when processing parameters (such as starter culture and fat content) and/or storage conditions are modified. It was found that the storage of milk powders increases both off-flavors and the amount of aroma active compounds. It was also determined that manipulating the starter culture of Cheddar cheeses can influence and direct flavor formation. Finally, in the large-scale production of Cheddar cheese, there are differences in the flavor.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Attention has been given to expand our knowledge in respect to the role of sulfur compounds in the flavor of aged cheddar cheese. A new method, based on the concentration of reduced thiol compounds and their analysis by a sulfur-specific GC detector shows the presence of 39 thiol compounds in the aged cheddar cheeses. Of these 14 were tentatively identified by Kovat's indices and the presence of 4-mercapto-4-methyl pentan-2-one confirmed with a pure standard. These 14 thiol compounds possess an additional alcohol, aldehyde, or ketone functional group. The results of this method were substantiated by other analyses (descriptive sensory analysis and electronic nose). Sensory analysis showed that there were four different sulfur descriptors (total sulfur, egg-like, match-like and catty) that differenced the eleven cheeses. Total sulfur and catty were correlated to age of the cheese and catty and match-like were also correlated. The electronic nose, using a mass spectrometer in NCI mode, gave similar differentiation patterns to the sensory and also suggest that 4-mercapto-4-methyl pentan-2-one was associated with the differentiation of the aroma. The three analytical approaches all confirm the importance of sulfur compounds to the flavor of aged Cheddar cheese and all help support the significance of the poly functional thiols in cheddar cheese flavor, especially the 4-mercapto-4methyl pentan-2-one (catty) compound. An additional 15 medium and higher molecular weight thiols were partially characterized by Kovat's Retention Indexes, and their molecular weights were estimated within a range of a few grams.

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.
