Sugar-free Toolbox – Bulk ingredients and intense sweeteners

Peter Jamieson, manager of food applications,Corn Products Specialty Ingredients, tracks down the evolution of sugar-free confectionery in response to consumer demand for better-tasting, “good-for-you” treats. Today’s sugar-free products are more diverse and offer a level of quality and taste equal to that of their sugar counterparts. Ingredient manufacturers and product developers alike have come up with creative and functional solutions for replacing the sugars without sacrificing taste or texture. Jamieson discusses the current tools – in the form of low digestible carbohydrates and high intensity sweeteners – available, that product developers favor to create these high-quality, reduced-sugar, no sugar added and sugar-free confections.

PMCA Committee Updates
Jeffrey Fine, director of new products and technology,AarhusKarlshamn, USAand PMCA Research Committee chair, sums up the committee’s activities to date, including current grant-in-aid research projects. As committee chair,Dennis Zak, consultant,TMResource, LLC, provides a brief report on past and future Education and Learning Committee activities, including results of past short courses and plans for the next year.

Free Volume – Why Hard Candy Gets Sticky
Rich Hartel, dept. of food science,University of Wisconsin-Madison, in collaboration withRenee LiethaandRajesh Bund, will cover theories of how moisture migrates within sugar glasses, recent experimental work on moisture penetration into hard candy, and potential methods of stabilizing sugar glasses against moisture problems. Even though hard candies – defined as glassy solids where the sugar molecules are found in a compact, but random, orientation – seem highly solidified, there is substantial free volume. Free volume is defined as the spaces between molecules into which small molecules can fit and move. Migration of water molecules into the sugar glass and diffusion of flavors out are related to the free volume within the glass.

Sweeteners: Providing Empty Calories or Functionality and Nutrition? The New Age of Functional and Nutrient Rich Caloric Sweeteners
Cheryl R. Mitchell, owner and chief research scientist ofCreative Research Management, investigates the world of functional and nutrient rich sweeteners, their physical properties, their availability as a commodity, and some of their distinctive and beneficial uses in formulations.

Gelatin Alternatives For Confectionery Products
Gregory R. Ziegler, professor of Food Science, in collaboration withLingyan Kong,a doctoral candidate, ThePennsylvania State University, examines strategies for gelatin replacement in a variety of confectionery products using other proteins, carbohydrate hydrocolloids and even lipids, depending on the properties of gelatin to be emulated. The ability to develop new textures in gelatin-based confections through the addition of a second hydrocolloid will also be examined.

Pearlescent Pigments – Making Confections Sparkle
Gale D. Myers, industry segment manager,Sensient Food Colors, explores the use of a new type of pigment, which the FDA permitted on July 5, 2006. Made with titanium dioxide and mica, this new colorant is a specific variety of a pearlescent pigment. Myers looks into the history and development of this pigment, an explanation of the U.S. regulations (where it can be used and at what levels), and how to use the material to manifest the sparkling effect in various confectionery applications.

Regulatory Update for the Confectionery Industry 2008
Alison Bodor, v.p.- regulatory & technical,National Confectioners Association, provides confectioners with an update on new industry regulations and issues affecting them in 2008 and beyond. She addresses the FDA's new food safety initiatives as well as its interest in revising the nutrition facts panel. An update on standards of identity for chocolate will also be shared.

Fundamental Mechanisms of Flavor Release/Perception in Confections
The PMCA’s Research Grant in Aid Project, which was conducted byAlicia Holts, a graduate student at ThePennsylvania State Universityunder the guidance ofDevin G. Peterson, associate professor of food science, reveals the results of extensive research conducted to define key flavor-flavor ingredient interactions that significantly influence flavor/release perception in hard candy. Results from both model systems (artificial mouth) and human trials (via breath analysis – real-time release kinetics of volatile flavor molecules)are analyzed. Findings surrounding the “flavor dosing” of the candy (flavor compounds added as a mixture or separately) and how this relates to practical applications in a manufacturing facility will also be discussed.

Chewing Gum Technology – Flavors & Textures
In his presentation, consultantDouglas Fritzanswers the following questions: What makes a chewing gum different from other confections? What is gum base and why are there different textures? How do flavorings and intense sweeteners interact with bulk sweeteners and gum base? And how can we achieve “longer lasting flavor?”

Food & Beverage Trends and Their Influence on Confections
Erin Kate O’ Donnell, marketing manager,David Michael Co., examines current flavor trends and future flavor predictions having an impact in the food and beverage industry and those likely to affect confections.

Awards Banquet
