• Brock research explores potential new tourism niche in Niagara through UN designation

  Tuesday, February 05, 2019 | By Brock University

  MEDIA RELEASE: 4 February 2019 – R00017

  Visitors coming to Niagara have lots to see and do thanks to the region being a top tourism destination.

  New research by Brock University’s Niagara Community Observatory (NCO) says there’s potential to enhance Niagara’s vibrant tourism industry if the region were to become a UNESCO Global Geopark.

  A Global Geopark is an area containing “sites and landscapes of international geological significance,” according to UNESCO.

  “Being designated a UNESCO Global Geopark allows Niagara to brand itself internationally as a destination for geotourism,” says Carol Phillips, author of the NCO’s policy brief Ohnia:kara, An Aspiring Global Geopark.

  “Niagara has a fascinating earth history that has created so many beautiful sites, culminating in Niagara Falls,” she says. “This brand allows us to showcase those sites as well as the history and culture that has developed around them.”

  The policy brief discusses the concept of a geopark in more detail, describes the efforts of the geographic educational non-profit  Geospatial Niagara to apply to become a geopark, offers case studies from other areas of the world and outlines next steps in the application process.

  The NCO will launch the policy brief Ohnia:kara, An Aspiring Global Geopark Thursday, Feb. 7 at Brock University. A panel will discuss the brief and the way forward for Niagara.

  What: Launching of NCO policy brief Ohnia:kara, An Aspiring Global Geopark

  When: Thursday, Feb. 7 from 9 to 11 a.m.

  Where: Room 207, Cairns Family Health and Bioscience Research Complex, Brock University

  Who: Carol Phillips, Research Co-ordinator, Niagara Community Observatory. Panelists: Darren Platakis, Geospatial Niagara, Ohnia:kara Steering Committee; David Fennell, Professor, Geography and Tourism, Brock University, Ohnia:kara Steering Committee; Walter Sendzik, Mayor, St. Catharines; Phil Davis, Indigenous Culture Liaison, Ohnia:kara Steering Committee.

• Beer a bitter pill to swallow for thermal tasters, says Brock research

  Monday, February 04, 2019 | By Brock University

  MEDIA RELEASE: 4 February 2019 – R00016

  Beer lovers widely agree that while the world’s most popular alcoholic drink can be slightly bitter or mildly sour, it’s pleasant overall. But for about 20 per cent of the population, beer is uncomfortably bitter and sour, a Brock University research team has found.

  ‘Thermal tasters’ are people who experience bitterness, sourness, astringency and other non-sweet flavours at a highly intense level. These tastes come out after the food or drink is swallowed, with the aftertaste lingering for up to two minutes.

  Professor of Biological Sciences and Psychology Gary Pickering says thermal tasters don’t even need to swallow food or drink to taste bitterness or sourness.

  “When we put a small probe on the tongue of someone who is a thermal taster and change the temperature, they taste bitterness or sourness, in effect, a ‘phantom taste’ because the taste comes from a temperature change to the tongue rather than food or drink,” he says.

  In earlier research, Pickering explored the thermal taster phenomenon. He and his team wanted to take the earlier research one step further, asking whether thermal tasters experience beer in a different way.

  In this latest research, published in the peer-reviewed journal Food Quality and Preference, 117 participants were asked to identify what they were tasting as they drank cold and warm samples of Molson Exel. They could choose any number of seven descriptors: astringent, bitter, carbonation, fruity/hops, malty, sour and sweet.

  A non-alcoholic beer was chosen for the trials so participants could swallow the drink (important for experiencing the full range of taste sensations) without their ratings or judgment being affected by alcohol, Pickering says.

  As an added twist, the participants in one of the trials listened to an audio clip of a can of cold beer being opened to see if that sound would enhance the sensation of carbonation during the tasting process.

  Participants were also tested to identify who were thermal tasters among the group.

  The researchers found that participants identified as thermal tasters reported the beer tasted bitter and sour at a higher rate than regular tasters, and they detected astringency and carbonation in cold beer more than warm beer. The sound clip of effervescence slightly enhanced thermal tasters’ ability to experience carbonation.

  Pickering explains that the addition of the sound clip is part of a growing research area called cross-modal interactions, which examines how one sense (in this case, hearing) may interact with another (taste) to alter how consumer products are experienced. Another example would be colouring a product yellow if the manufacturer wanted it to taste more sour and citrus-like.

  Also, thermal tasters’ ability to perceive flavours just by changing the temperature of their tongue might be a result of “cross-wiring” of taste nerves and trigeminal nerves in the oral cavity, says Pickering.

  Taste nerves respond to sweetness, sourness, bitterness and other flavours, while trigeminal nerves are responsible for the sensations such as hot, cold and spiciness experienced when eating and drinking.

  “Thermal tasting may be a proxy for general taste sensitivity,” he says.

  Pickering says thermal tasters’ heightened sensitivity to bitterness and sourness “may be protective against alcohol misuse,” as thermal tasters would be less likely to start, or continue, drinking, since many alcoholic beverages would elicit these tastes at unpleasant levels.

  He says the research results might also have implications for breweries and marketing experts, and that further research might explore how beer could be optimized for individuals such as thermal tasters who have different taste sensitivities.

  “This research highlights that many factors influence flavour,” says PhD candidate Margaret Thibodeau, who is one of the study’s authors.

  “More research is required to better understand the perception of alcoholic beverages,” she says.

  To that end, Thibodeau is conducting another study that examines how thermal tasters perceive ethanol – the active ingredient in alcoholic beverages – compared to non-thermal tasters.

  She is looking for female volunteers ages 19 to 40 to participate in that study. For more information, email [email protected]
