This book was released on 2002 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Odor-active volatile compounds, which are mostly responsible for the flavors during eating, need to be released above the buccal headspace in order to be perceived as flavors. Development of a novel instrumentation method that can represent the in-mouth environment will serve as a useful tool in understanding the flavor release during eating in different food matrices. The objective of this experiment was to understand the release behavior of flavor components during mastication using odor-active flavor compounds in ice creams with various amounts of fat and fat replacers. Instrumental methods that can analyze the overall and the temporal changes of the volatile profile in an ice cream during eating were developed. Overall volatile profiles of the ice creams varying in fat and flavor levels were analyzed by GC-MS utilizing three extraction methods, Purge and Trap (PT), Direct In-Nose Breath Analysis (DINBA), and Modified Dynamic Headspace (MDH). Also the temporal volatile profile of the ice cream using temporal DINBA (TDINBA) and Temporal Modified Purge and Trap (TMPT) were investigated. The overall and temporal volatile profiles were correlated with the sensory flavor profiles obtained by Descriptive Analysis (DA) and Time-Intensity (TI), respectively. DA, TI, MPT, and TMPT analyses were then applied to investigate the interactions between flavor-volatiles and fat replacers (FR), i.e. a carbohydrate (CFR) or a protein (PFR) based fat replacer, in reduced fat cherry flavored ice creams. The overall and temporal volatile profile acquired by MDH and TMPT correlated well with the corresponding sensory flavor profiles. The results obtained by DINBA varied widely between and within subjects, consequently, the effect of fat on flavor release pattern was not clearly demonstrated using this method. Fat significantly affected the chemical and sensory flavor release of ice cream. Decreasing fat content increased amounts of aldehydes responsible for stale flavor but decreased the amounts of methyl ketones associated with cream flavor being released when PT and MDH were used as extraction methods. Hexanal (stale) and benzaldehyde (cherry), both chemically and perceptually, were released faster and at higher intensity as fat content decreased whereas, vanilla flavor was released faster and at higher intensity as fat level increased. The performance of FRs for mimicking milk fat varied depending on the fat content of the original ice cream. PFR more than CFR behaved similarly to milk fat in low fat ice cream from both chemical and sensory aspect. However, CFR was more effective than PFR in mimicking milk fat in full fat ice cream when it was added to the ice cream mix containing more than 6% of milk fat. Employing MPT and TMPT methods for flavor analysis provided a better insight into the flavor release pattern during eating from the ice cream with various levels of fat and fat replacers. This approach, integrated with sensory analysis, might facilitate the reformulation of a flavoring for lower fat products so that the flavor of the products will be improved to resemble those of the corresponding original products.
Book Synopsis Sensory Analysis of Low Fat Strawberry Ice Creams Prepared with Different Flavor Chemicals and Fat Mimetics by : Bo-Kang Liou
Download or read book Sensory Analysis of Low Fat Strawberry Ice Creams Prepared with Different Flavor Chemicals and Fat Mimetics written by Bo-Kang Liou and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to understand the release behavior of five strawberry flavor compounds in ice cream with fat mimetics, and to reformulated low-fat ice cream with Simplesse® to match the flavor profile of full-fat ice cream. FuraneolTM was perceived more strongly in full-fat ice cream, while cis-3-hexen-1-ol, [alpha]- ionone, [gamma]-undecalactone and ethyl-3-methyl-3-phenylglycidate were perceived more strongly in low-fat ice cream. However, ice creams with Simplesse® and full-fat ice cream had similar sensory characteristics. Cooked sugar flavor, sweetness and their aftertastes were determinants for the degree of taste similarity with full-fat ice cream. The reformulated product, which was the closest in sensory characteristics to full-fat ice cream, was either the one in which the concentration of [gamma] undecalactone was decreased individually by 25% or the product, in which [gamma] undecalactone and cis-hexen-1-ol were decreased by 25%. No significant differences for consumer test between the reformulated products and full-fat ice cream.
Book Synopsis Impact of Five Flavor Compounds on Full and Low Fat Strawberry Mix and Ice Cream by : Shakira Loeb
Download or read book Impact of Five Flavor Compounds on Full and Low Fat Strawberry Mix and Ice Cream written by Shakira Loeb and published by . This book was released on 2004 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a recent increase in health conscious people, which have led to an increased demand for low and no fat foods that taste like full fat foods. Ice cream is an ideal vehicle for this study since it has a very complex ingredient matrix. Strawberry flavor is used because it has diverse character impact compounds. This study's objective was to determine how five components of an artificial strawberry flavoring affect the flavor of a full fat (10%) and low fat (4%) ice cream and mix using flavor spiking, instrumental (GC/MS & HPLC) and descriptive analysis. cis -3-Hexen-1-ol (grassy), furaneol (caramel), [gamma]-undecalactone (peach), [alpha]-ionone (floral/violet) and ethyl-3-methyl-3-phenylglycidate (candy) were collectively used to create an artificial strawberry flavor. To determine the impact of each of these compounds on the strawberry flavor, each was spiked at 200% of normal level separately into both ice cream mixes and ice creams. A 4 and 10% fat control flavors at normal levels were used for comparison. Descriptive analysis showed separation based on fat level but not for instrumental analysis. Ethyl-3-methyl-3-phenylglycidate and furaneol were perceived stronger in 10% ice cream and mix while [alpha]-ionone and [gamma]-undecalactone were perceived strongest in 4% ice cream and mix. The 10% and 4% mix and ice cream controls were most affected by cis -3-hexene-1-ol.

Book Synopsis Time-Dependent Measures of Perception in Sensory Evaluation by : Joanne Hort
Download or read book Time-Dependent Measures of Perception in Sensory Evaluation written by Joanne Hort and published by John Wiley & Sons. This book was released on 2017-02-21 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sensory evaluation is a scientific discipline used to evoke, measure, analyse and interpret responses to products perceived through the senses of sight, smell, touch, taste and hearing. It is used to reveal insights into the way in which sensory properties drive consumer acceptance and behaviour, and to design products that best deliver what the consumer wants. It is also used at a more fundamental level to provide a wider understanding of the mechanisms involved in sensory perception and consumer behaviour. Sensory perception of products alters considerably during the course of consumption/use. Special techniques are used in product development to measure these changes in order to optimise product delivery to consumers. Time-Dependent Measures of Perception in Sensory Evaluation explores the many facets of time-dependent perception including mastication and food breakdown, sensory-specific satiety and sensory memory. Both traditional and cutting-edge techniques and applications used to measure temporal changes in sensory perception over time are reviewed, and insights into the way in which sensory properties drive consumer acceptance and behaviour are provided. This book will be a valuable resource for sensory professionals working in academia and industry, including sensory scientists, practitioners, trainers and students; and industry-based researchers in QA/QC, R&D and marketing.

Book Synopsis Food Flavour Technology by : Andrew J. Taylor
Download or read book Food Flavour Technology written by Andrew J. Taylor and published by John Wiley & Sons. This book was released on 2009-12-15 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food flavour technology is of key importance for the food industry.Increasingly, food products must comply with legal requirements andconform to consumer demands for “natural” products, butthe simple fact is that, if foods do not taste good, they will notbe consumed and any nutritional benefit will be lost. Thereis therefore keen interest throughout the world in the production,utilisation and analysis of flavours. The second edition of this successful book offers a broadintroduction to the formulation, origins, analysis and performanceof food flavours, updating the original chapters and addingvaluable new material that introduces some of the newermethodologies and recent advances. The creation of flavourings is the starting point for the book,outlining the methodology and constraints faced byflavourists. Further constraints are considered in a chapterdealing with international legislation. The origins of flavours aredescribed in three chapters covering thermal generation,biogeneration and natural sources, keeping in mind the adjustmentsthat manufacturers have had to make to their raw materials andprocesses to meet the demand for natural products whilst complyingwith cost issues. Delivery of flavours using encapsulation orthrough an understanding of the properties of the food matrix isdescribed in the next two chapters, and this section is followed bychapters describing the different ways to analyse flavours usinginstrumental, modelling and sensory techniques. The book is aimedat food scientists and technologists, ingredients suppliers,quality assurance personnel, analytical chemists andbiotechnologists.

Book Synopsis Physico-Chemical Aspects of Food Processing by : S.T. Beckett
Download or read book Physico-Chemical Aspects of Food Processing written by S.T. Beckett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food processing is now the biggest industry in the UK and in many other countries. It is also rapidly changing from what was essentially a craft industry, batch processing relatively small amounts of product, to a very highly automated one with continuously operating high speed production lines. In addition, consumers have developed a greater expectation for consistently high standard products and coupled this with demands for such things as a more natural flavour, lower fat etc. The need for an increased knowledge of the scientific principles behind food processing has never been greater. Within the industry itself, increased automation, company diversification and amalgamations etc. have meant that those working in it have often to change their field of operation. Whereas twenty years ago, someone starting work in one branch of the food industry could expect, if he or she so desired, to work there all their working lives, this is now seldom the case. This means that a basic knowledge of the principles behind food processing is necessary both for the student at university or college, and for those already in the industry. It is hoped, therefore, that this book will appeal to both, and prove to be a useful reference over a wide range of food processing.
