PETITS FOURS Temperature and the intensity of taste Can the temperature of food affect the intensity of its taste? It depends on the taste, according to a study by Gary Pickering and colleagues from Brock University in Canada. Their work shows that changes in the temperature of foods and beverages have an effect on the intensity of sour, bitter and astringent (cranberry juice, for example) tastes, but not sweetness. Their work is published online in Springer’s Chemosensory Perception journal. We are all familiar with the effect of temperature on taste — think about starting to eat or drink something while it is warm and finishing when it has cooled, or vice versa. The same food or beverage may taste different depending on its temperature. In addition, in 20% to 30% of the population, heating or cooling small areas of the tongue elicits a taste sensation without the presence of food or drink. These individuals are known as “thermal” tasters. Over three sessions, 74 participants recruited from Brock University and the local community — a combination of ‘thermal’ tasters, ‘super’ tasters, people who are particularly sensitive to tastes in general, and ● ● ● ‘regular’ tasters — tasted sweet, sour, bitter and astringent solutions at both 5°C and 35°C. They were then asked to rate the intensity of the tastes over a period of time. For all three types of tasters, temperature influenced the maximum perceived intensity from astringent, bitter and sour solutions, but not from the sweet solutions. Specifically: ● astringency was more intense when the solution was warm, and the intensity of the flavor lasted longer with the warm solution than with the cold one bitterness was more intense with the cold solution, and the flavor intensity declined faster with the cold solution than with the warm one sourness was more intense with the warm solution, and the flavor intensity lasted longer with the warm solution than with the cold one surprisingly, there was no difference in perceived sweetness between the cold and warm sugar solutions, but it took longer for the cold solution to reach its maximum flavor intensity. The authors concluded: “For some individuals, temperature alone can elicit taste sensations. These individuals seem to be more sensitive to tastes in general. What our work shows is that, in addition to these sensitive individuals, the temperature of a specific taste can affect how intense it tastes.” AD INDEX Almond Board of California _____ 15 www.almondboard.com French’s Flavor Ingredients______ 10 www.frenchsflavoringredients.com Integrative Flavors _____________ 28 www.cooksdelight.com Barry Callebaut _______________ 43 www.barry-callebaut.com GPI Inc. _______________________ 2 www.gpiglobal.com Kikkoman International, Inc. _____ 7 www.kikkomanusa.com Black Boar Truffle, LLC _________ 41 www.blackboartruffle.com Gum Technology ______________ 33 www.gumtech.com MGP Ingredients, Inc. _________ 5, 9 www.mgpingredients.com ConAgra Mills ________________ 11 www.conagramills.com IDF/International Dehydrated Foods _____________ 44 www.idf.com Mizkan Americas, Inc. __________ 29 www.mizkan.com DuPont Nutrition & Health _____ 35 www.danisco.com Research Chefs Association _____ 27 www.culinology.org/annualconference Ingredion _________________ 16, 17 www.ingredion.com/us Eatem Foods Co. ______________ 26 www.eatemfoods.com Siemer Specialty Ingredients ______ 6 www.siemerspecialtyingredients.com Innovadex LLC ________________ 23 www.innovadex.com 42 | Culinology | MAY/JUNE 2012 http://www.almondboard.com http://www.cooksdelight.com http://www.frenchsflavoringredients.com http://www.barry-callebaut.com http://www.gpiglobal.com http://www.kikkomanusa.com http://www.blackboartruffle.com http://www.gumtech.com http://www.mgpingredients.com http://www.conagramills.com http://www.mizkan.com http://www.idf.com http://www.danisco.com http://www.culinology.org/annualconference http://www.ingredion.com/us http://www.eatemfoods.com http://www.siemerspecialtyingredients.com http://www.innovadex.com
