Your sense of taste, smell, sight, hearing and touch sends signals to your brain that the holiday feasting season has arrived. These basic senses are the tools that influence how much you like – or dislike – the foods you eat.
Sensory evaluation also has practical applications in agriculture. UC Agriculture and Natural Resources researchers and their colleagues often conduct sensory panels for specific food crop studies. Recently volunteer evaluators filed into the sensory evaluation lab at the UC Kearney Agricultural Research and Extension Center to participate in a grape sensory panel. UC researcher Mary Lu Arpaia and USDA researcher David Obenland collected data for a study on the impacts of various storage conditions on grape varieties.
“There's a bit of psychology involved as well. How the product looks can influence your perception of how it tastes. To further eliminate bias, evaluators are intentionally isolated in individual stations so as not to be influenced by their neighbors' reactions,” explained David Obenland.
The sensory evaluation lab at the Kearney Agricultural REC reflects the current philosophy of fruit commodity research that the industry's focus should be on sensory evaluation, from new pest management to horticultural practices to varietal improvements. The lab was completed and dedicated in April 2008 with support from the California Avocado Inspection Committee, Citrus Research Board, Food Machinery Corporation, Peach, Plum and Nectarine Growers of California, Sunkist and Table Grape Commission.

UC Cooperative Extension in San Joaquin County will host the SJC and Delta Field Crops Meeting on Friday, January 8, 2016 from 8:00am to 12:00pm. The meeting location is the Cabral Agricultural Center in Stockton (2101 E.Earhart Ave., Stockton, CA...
UC Hopland Research and Extension Center (UC HREC) will host workshops on Dec. 1 and 2 to foster understanding and encourage community dialog about ranching on a landscape with populations of coyote, black bear, mountain lions and other wildlife.
“Mendocino County supports many ranchers and our communities enjoy locally produced lamb, beef, milk, cheese and other agricultural products,” said Kimberley Rodrigues, director of UC HREC. “Along with these opportunities come challenges associated with living alongside some of our resident wildlife. The workshops will help local residents deal with these challenges.”
Rodrigues – who has a doctorate degree in environmental science and has been a leader in outreach, strategic facilitation and partnership development for 25 years – has been actively involved in wildlife management at the 5,300-acre HREC since she arrived in mid-2014.
“I quickly realized the biggest challenge to maintaining a sustainable flock of sheep here in our location is addressing predation issues, primarily by coyotes,” Rodrigues said. “With some improvements to our fences, changes in pasture rotations and increased use of guard dogs, losses of sheep to coyotes are now at an acceptable level. We hope to share our own experience, hear from diverse perspectives and experiences at these events and would like HREC to become a hub for future learning on this topic.”
Recent discussion and decisions made by the Mendocino County Board of Supervisors regarding their contract with USDA Wildlife Services (WS) and their use of an integrated wildlife damage management program prompted UC HREC to provide a space for two workshops to allow learning on wildlife management and community conversation.
The Dec. 1 workshop will focus on scientific design and is implemented by USDA WS. It provides an opportunity to hear experts from USDA, the Californi Department of Fish and Wildlife, UC Cooperative Extension and Defenders of Wildlife to discuss the most up-to-date research in wildlife behavior and non-lethal control methods.
The Dec. 2 community conversation workshop is hosted by UC HREC and includes current research from UC Agriculture and Natural Resources, wildlife biologists and discussion of the challenges associated with ranching in Mendocino County from the Magruder family and other local ranchers. The day will culminate in discussion groups on topics ranging from integrated wildlife management tools to understanding local, state and federal connections.
The public may attend either day or both days. Registration for the two workshops is separate.
“Topography, surrounding environments, community viewpoints, available funds and the kind of animals being farmed are all part of the picture – there is no easy solution,” said Hannah Bird, UC HREC community educator. “Ranchers and land managers need to know what tools are available to them and the implications and benefits of each of these tools. Attending both workshops will provide a deeper understanding of the issues.”
Community members, ranchers, land managers and members of non-profit organizations are invited to attend. The workshops will be at the Rod Shippey Hall, Hopland Research and Extension Center, 4070 University Road, Hopland, CA 95449. Registration is $30 for each day (including lunch) and must be made in advance. The registration deadline is Nov. 23. Space is limited.
