To get the full flavor, you need the right temperature

Study highlights the effect of temperature on intensity of flavors in the mouth

2012-05-15
(Press-News.org) Can the temperature of the food we eat affect the intensity of its taste? It depends on the taste, according to a new study by Dr. Gary Pickering and colleagues from Brock University in Canada. Their work shows that changes in the temperature of foods and drinks have an effect on the intensity of sour, bitter and astringent (e.g. cranberry juice) 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 can taste different depending on its temperature. In addition, in 20-30 percent of the population, heating or cooling small areas of the tongue draws out 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 i.e. people who are particularly sensitive to tastes in general, and 'regular' tasters) tasted sweet, sour, bitter and astringent solutions at both 5oC and 35oC. 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 and, 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 conclude: "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."

Keranique Launches Unique Hair Rejuvenation Kit

Keranique is a hair care company that is changing this method of shopping by launching a hair care kit that includes all of the items consumers need to get results. Among these items is a product that includes an FDA-approved ingredient that contributes to hair regrowth. Keranique has ...

UTSA study finds ovulating women perceive sexy cads as good dads

2012-05-15
(San Antonio)—Nice guys do finish last at least when it comes to procreation according to a study from The University of Texas at San Antonio that answers the question of why women choose bad boys. Research from Kristina Durante, assistant professor of marketing at The University of Texas at San Antonio (UTSA) College of Business, finds that hormones associated with ovulation influence women's perceptions of men as potential fathers. "Previous research has shown in the week near ovulation women become attracted to sexy, rebellious and handsome men like George Clooney ...

School politics increasingly important to Swedish voters

2012-05-15
Education is a growing political issue in Sweden, school politics is becoming increasingly important to Swedish voters in elections to parliament, and the share of voters who support the school politics of the Liberal Party has increased. These are three trends pointed out in new reports from the University of Gothenburg, Sweden. The three reports are based on longitudinal voter behaviour studies that started in 1979 and 1987. The new updates concern the period between the elections in 2006 and 2010. Maria Jarl, political scientist who is studying school politics, has ...

Jim Nyquist Responds to New York Times "House Flipping" Criticism

2012-05-15
In recent years, there has been much ink spilled on the subject of why the housing industry has taken such a dive--or at least, why it is less robust than it once was. Some experts say that it is simply the result of a tumultuous economy, but the New York Times has a different theory. In a recent article on the proliferation of "house flipping" TV shows, the publication muses that the decline in real estate sales may be directly related to the dim view that these TV programs take of real estate investment. Indeed, the Times piece declares that real estate-themed ...

A walk in the park gives mental boost to people with depression

2012-05-15
Toronto, CANADA – A walk in the park may have psychological benefits for people suffering from depression. In one of the first studies to examine the effect of nature walks on cognition and mood in people with major depression, researchers in Canada and the U.S. have found promising evidence that a walk in the park may provide some cognitive benefits. The study was led by Marc Berman, a post-doctoral fellow at Baycrest's Rotman Research Institute in Toronto, with partners from the University of Michigan and Stanford University. It is published online this week, ahead ...

New species of fish in Sweden

New species of fish in Sweden
2012-05-15
Reticulated dragonet have been found in Väderöarna – "Weather Islands" – off the west coast of Sweden. It is not often that a new species of fish is discovered in Sweden. Lars-Ove Loo is the underwater photographer who has captured the fish on film. He saw it while making an inventory ahead of the creation of a new nature reserve in the islands. This was in August 2010, 19 meters below the surface of the sea south of Lyngö in the southern Väderöarna (58° 32.554' N, 11° 05.373' E). Reticulated dragonet (Callionymus reticulatus) is similar to its more common Swedish relatives ...

A microRNA prognostic marker identified in acute leukemia

2012-05-15
COLUMBUS, Ohio – A study has identified microRNA-3151 as a new independent prognostic marker in certain patients with acute leukemia. The study involves patients with acute myeloid leukemia and normal-looking chromosomes (CN-AML). The study by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) found that when microRNA-3151 (miR-3151) is overexpressed in CN-AML, the disease responds poorly to treatment and patients experience shorter remissions and survival periods. ...

Research: Too much, too little noise turns off consumers, creativity

Research: Too much, too little noise turns off consumers, creativity
2012-05-15
CHAMPAIGN, Ill. — The sound of silence isn't so golden for consumers, and both marketers and advertisers should take note, says new research from a University of Illinois expert in new product development and marketing. According to published research from Ravi Mehta, a professor of business administration, ambient background noise turns out to be an important factor affecting creative cognition among consumers. "We found that ambient noise is an important antecedent for creative cognition," Mehta said. "A moderate level of noise not only enhances creative problem-solving ...

Children's brain tumors more diverse than previously believed

2012-05-15
Paediatric brain tumours preserve specific characteristics of the normal cells from which they originate – a previously unknown circumstance with ramifications for how tumour cells respond to treatment. This has been shown by Uppsala researcher Fredrik Swartling together with colleagues in the U.S., Canada and England in a study that was published today in the distinguished journal Cancer Cell. Every year, 80-90 children in Sweden are afflicted with brain tumours, a serious form of paediatric cancer. Today, three of four children who receive treatment survive. The ...
