This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, the food industry has been seeking to reduce the energy density of many products. Fat reduction is often pursued as a strategy to decrease the overall caloric content of foods, since it provides the highest amount of energy per gram (9 kcal/g), when compared to proteins and carbohydrates (4 kcal/g). However, fat-reduced products are often perceived to be of inferior sensory quality, when compared to the full-fat alternative.Ice cream is a complex food matrix due to the coexistence of multiple physical phases: ice crystals, air bubbles, partially coalesced fat globules and a concentrated, highly viscous unfrozen solution. In ice cream, removal of one ingredient may affect not only physical properties but also multiple sensory characteristics that are important to consumers. Fat, in particular, contributes to texture, mouthfeel and flavor, in addition to serving as a structural agent supporting the other physical phases, in particular the air bubbles. Moreover, it contributes to the characteristic smoothness, dryness and melting rate of the products. Removal of fat from ice cream without replacement of solids has been shown to decrease sensory quality indicators, while the addition of ingredients to replace the fat has provided better results. However, the perfect replacement strategy has yet to be found. Previous work evaluating fat removal strategies has focused on changes in key sensory descriptors, with surprisingly little information available about consumer acceptability of reduced-fat products.In this study, the effect of replacing fat with maltodextrin (MD) on selected physical properties of ice cream and on consumer acceptability were evaluated simultaneously. Vanilla ice creams were formulated to contain 6, 8, 10, 12 and 14% fat and 8, 6, 4, 2, and 0% maltodextrin, respectively. Physical characterization included measurements of overrun, apparent viscosity, fat particle size, fat destabilization, hardness and melting rate. A series of consumer acceptability tests were conducted, each with ~100 participants, to measure liking and intensity of various sensory attributes. The experiment was replicated three times. Data were analyzed using one-way Analysis of variance (ANOVA) and a mixed model ANOVA for the physical and sensory data, respectively. Correlation analysis was used to assess relationships between consumer acceptability, physical variables and sensory attributes. Consumer tests were also conducted after 19 weeks of storage at -18C, to assess changes in sensory acceptance due to prolonged periods of storage. Later, a discrimination test was used to determine the difference in fat content that consumers are able to discriminate among the products tested in this study. Results indicated that viscosity of the mixes decreased with increasing fat content and decreasing maltodextrin concentration. Fat particle size and fat destabilization significantly decreased with fat reduction. However, consumer acceptability did not significantly differ across the samples for fresh or stored ice cream. Even in the absence of significant differences, overall liking was correlated with slower melting rate in fresh ice cream. Following storage, ice creams with 6, 12 and 14 % fat did not differ in consumer acceptability compared to fresh ice cream. However, ice creams with 8 and 10% fat (and 6 and 4% MD), each showed a significant drop in liking score following storage by 2.8 and 5.7%, respectively. When asked to discriminate, consumers were unable to distinguish ice creams with 2% fat difference when maltodextrin was included in the formulation. A 4% difference was found to be discriminated when comparing 6% vs 10% fat ice creams but not for 8% vs 12% fat. Collectively, the changes in the physical structure of ice creams with fat contents ranging from 6 to 14% did not show evidence of gross changes in consumer acceptability for either fresh or aged ice cream.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ice cream, produced in millions of gallons, has been a favorite comfort food to many people since its development centuries ago. Vanilla ice cream has long been a staple in the ice cream industry with its production and consumption being the highest when compared to other flavors. Since many consumers want more "natural" foods, the objective of this study was to study the effect of labeling the type of vanilla flavoring on consumer perception of commercial ice cream and laboratory-produced vanilla ice cream. Four commercial vanilla ice creams, one containing natural vanilla, one with artificial, and two containing both, were evaluated by several sensory panels. Nine-point hedonic scales were used to evaluate overall liking, appearance, color, flavor, vanilla flavor, sweetness and 9-point intensity scales were used to evaluate the strength of vanilla flavor and the strength of sweetness of the commercial ice creams. When the samples were not labeled with the type of vanilla flavoring, ANOVA data showed that the naturally flavored ice cream was not liked as well as the ice cream with mixed flavorings overall and for vanilla flavor. When the samples were labeled with the type of vanilla flavoring, the artificially flavored ice cream was not liked as well as the mixed flavored ice creams. The naturally flavored ice cream was liked as well as one of the mixed flavored ice creams overall and for flavor and vanilla flavor. Another experiment was conducted with an incomplete block design (n=150) with the same four ice creams being labeled (correctly or incorrectly) for twelve combinations. No overall, flavor, vanilla flavor, or sweetness differences in hedonic scores existed among the products, yet differences did exist between the ice creams with particular labels no matter which product was used. Products labeled "natural" were liked more (p

Available in PDF, EPUB and Kindle. Book excerpt: The ?eld of sensory science has grown exponentially since the publication of the p- vious version of this work. Fifteen years ago the journal Food Quality and Preference was fairly new. Now it holds an eminent position as a venue for research on sensory test methods (among many other topics). Hundreds of articles relevant to sensory testing have appeared in that and in other journals such as the Journal of Sensory Studies. Knowledge of the intricate cellular processes in chemoreception, as well as their genetic basis, has undergone nothing less than a revolution, culminating in the award of the Nobel Prize to Buck and Axel in 2004 for their discovery of the olfactory receptor gene super family. Advances in statistical methodology have accelerated as well. Sensometrics meetings are now vigorous and well-attended annual events. Ideas like Thurstonian modeling were not widely embraced 15 years ago, but now seem to be part of the everyday thought process of many sensory scientists. And yet, some things stay the same. Sensory testing will always involve human participants. Humans are tough measuring instruments to work with. They come with varying degrees of acumen, training, experiences, differing genetic equipment, sensory capabilities, and of course, different preferences. Human foibles and their associated error variance will continue to place a limitation on sensory tests and actionable results. Reducing, controlling, partitioning, and explaining error variance are all at the heart of good test methods and practices.

Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Dairy Chemistry series was first published in four volumes in the 1980s (under the title Developments in Dairy Chemistry) and revised in three volumes in the 1990s and 2000s. The series is the leading reference on dairy chemistry, providing in-depth coverage of milk proteins, lipids, lactose, water and minor constituents. Advanced Dairy Chemistry Volume 2: Lipids, Fourth Edition, is unique in the literature on milk lipids, a broad field that encompasses a diverse range of topics, including synthesis of fatty acids and acylglycerols, compounds associated with the milk fat fraction, analytical aspects, behavior of lipids during processing and their effect on product characteristics, product defects arising from lipolysis and oxidation of lipids, as well as nutritional significance of milk lipids. In the years since the publication of the third edition there have been significant developments in milk lipids and these are reflected in changes to this volume. Most topics included in the third edition are retained in the current edition, which has been updated; in some cases, new authors have given their perspective on certain topics. Chapters on nutritional significance of dairy lipids have been considerably revised. This authoritative work summarizes current knowledge on milk lipids and suggests areas for further work. It will be very valuable to dairy scientists, chemists and others working in dairy research or in the dairy industry.
