June/July 2020
With the COVID-19 pandemic, The University of Nebraska-Lincoln has closed buildings to the general public and moved all classes to remote learning until August 24, 2020. This includes classes being held on Nebraska Innovation Campus. Faculty, staff, and students have put in much work as the changes necessary are made to meet obligations. At this time only activities and functions of the Department and the Center that have been deemed mission-critical are up and running for day-to-day operations. We are expecting to be working remotely through most of July. If you have any questions or concerns please contact us at foodsci@unl.edu or 402-472-2831.
Dr. Jayne Stratton and Dr. Andreia Bianchini, faculty from the Department of Food Science and Technology, provided engaging presentations about food safety and microbiology to high school students during the 4-H Virtual Summer Camp. Students learned about methods used to control bacterial growth and prevent foodborne illnesses from pathogenic bacteria. Students also participated in virtual lab sessions in the food microbiology lab, where samples of milk and hamburger patties were evaluated for proper cooking and processing. Students were able to observe the importance of probing temperature while cooking meats and how microorganisms can be enumerated in the lab.  
Presenters asked students what they can do at home to make foods last longer? Students suggested refrigeration, salting foods, and canning.
Video showed the cooking of two hamburgers patties to different temperatures, one at 109oF and the other to 165oF. The latter is the safe cooking temperature recommended by food safety experts.
A sample of the hamburger patties was taken from the center of the hamburger by a swab.
Next, the swab was streaked across agar on a petri dish and placed in an incubator for 2 days to allow bacteria, if present in the hamburger patties, to grow.
To assist in addressing safety concerns with campus operations during the pandemic, The Food Processing Center has been making 25,000 gallons of FDA-approved hand sanitizer for campus use. A special thanks goes out to Green Plains for the donation of 21,000 gallons of ethanol used in the sanitizer.

An innovative solution for dispensing the sanitizer within buildings on campus was developed by University Operations, along with a team in University Housing.  They created a free-standing large-capacity
dispenser station as shown in the photo on left.  Dispensing stations will allow for access to free hand sanitizer throughout campus.
Dr. Ozan Ciftci was featured on the AOCS newsletter as a Young Scientist to Watch. The AOCS Young Scientists to Watch initiative is directed at scientists in the early stages of their career who are conducting transformative research in the area of fats, oils, oilseed proteins, and related materials. The recognition is given to feature scientists whose research “has significantly advanced scientific understanding within their discipline or holds substantial promise for such an impact in the near future.” You can read the article in full at https://aocs.onlinelibrary.wiley.com/hub/young-scientists-to-watch

Additionally,  Dr. Ozan Ciftci gave a webinar entitled “Developing health and wellness promoting advanced food lipids and lipophilic bioactives using supercritical carbon dioxide” to Cargill as part of Cargill’s external innovation strategy (Pillar 4 – Global Capabilities) that hosts some industry leading technical voices.  The webinar was organized for the Cargill scientists from North America, Latin America, Europe, and Asia.
Safe Cleaning with Chemicals

Using chemical cleaners without proper safety procedures can cause injuries or even fatalities. Always follow these guidelines.
  1. Check labels on cleaners before using them to learn about risks.
  2. Keep cleaners locked up and away from children and pets.
  3. Don't mix cleaners.
  4. Never mix bleach with anything (it can have toxic reactions with many other substances).
  5. Make sure to use cleaners in a well-ventilated area
  6. If an accidental mixture occurs don't try to clean it up or neutralize it. Get out of the area and call 911.
