Nettle Oil vs. Bacteria: Pizza Cheese Gets a Science Upgrade! #sciencefather #researchawards #NettleOilScience #SmartFoodSafety

 

 A Natural Defender on the Rise
In a delicious twist for food science, recent studies have shown that nettle (Urtica dioica L.) essential oil may offer a powerful and natural way to fight off harmful bacteria in pizza cheese. This pungent green plant, long known for its medicinal properties, is stepping into the spotlight in food preservation. Researchers are exploring its use as a natural antimicrobial agent that could significantly reduce bacterial contamination in dairy products, especially in high-risk foods like cheese.

Why Pizza Cheese Needs Protection
Pizza cheese, with its high moisture and fat content, provides an ideal breeding ground for pathogens like Listeria monocytogenes, Staphylococcus aureus, and Escherichia coli. While preservatives have long been used to tackle these microbial threats, consumers are now demanding cleaner labels and healthier alternatives. This has fueled interest in plant-based antimicrobial solutions like nettle oil, which not only extend shelf life but also align with natural and organic food trends.

 The Power of Pickering Nanoemulsions
To enhance nettle oil’s effectiveness, scientists are combining it with Pickering nanoemulsions—advanced delivery systems that encapsulate the oil in nanoparticles. These emulsions help the essential oil disperse evenly in the cheese matrix, ensuring sustained antimicrobial activity. Studies have shown that this combination can inhibit bacterial growth more effectively than traditional preservatives, offering a potent, plant-powered alternative.

 Flavor Meets Function
One of the key concerns with introducing essential oils into food is flavor alteration. However, when properly formulated, nettle oil in nanoemulsions adds negligible flavor impact while delivering strong antimicrobial benefits. This means consumers can enjoy their favorite cheesy pizza with peace of mind, knowing that it's both delicious and safer from harmful microbes.

 The Future of Functional Foods
As the food industry continues to innovate, natural preservatives like nettle oil are paving the way for smarter, cleaner, and more functional foods. With increasing consumer awareness and scientific validation, we’re entering an era where everyday favorites like pizza cheese are not only tastier but also healthier and safer. This science upgrade promises to be a game-changer in the battle against foodborne illness—one slice at a time.

Chicken will continue to meet the needs of consumers in 2035

Image
In the decade ahead, fast prep time, easy-to-prepare, single-serve packaging and other time savers will be priorities for Gen Z and younger Millennials who buy fresh chicken, according to research presented today at the 2024 Chicken Marketing Summit. More than two-thirds (71%) of consumers surveyed said they now spend more than 30 minutes preparing a typical evening meal. Gen Z spends the most time preparing dinner, with almost a third spending an hour or more on a typical evening meal. 67% of Gen Z say that fast prep will be a priority in five years. “Beyond speed, Gen Z indicates a future need for advance meal prep, global flavors and minimal clean-up,” according to Joyce Neth, WATT Global Media. “Meal kits, packaging that offers no mess and labels with information on nutrition are especially appealing to Gen Z who in five years will likely be in a different stage of lifestyle, balancing work and families. The National Chicken Council (NCC) and WATT Global Media presented the results...

KFC's lab-grown chicken efforts might lead QSRs

Image
When KFC Russia said last month that it hoped to launch and sell lab-produced chicken nuggets, advocates of Earth-friendly protein sources were ebullient for what it could mean for the environment. To create the nuggets, KFC Russia and 3D Bioprinting Solutions use 3D printing technology, a move that Yum Brands, KFC's parent company, said could it meet the demand for both sustainable products and alternatives to traditionally derived meats. KFC — which did not respond to QSRweb's requests for additional information — has been relatively tight-lipped about the initiative. That hasn't stopped scientists and members of the Good Food Institute — a non-profit Washington, D.C.-based alternate protein source advocacy group — from being overjoyed, however.

Skills should a Food Scientist Have

Image
The majority of food technologists, food scientists, and soil and plant scientists earn a bachelor's degree. Some scientists will go on to earn a Doctorate of Veterinary Medicine (DVM). Education & Training Agricultural Science degrees are offered by numerous land-grant colleges in every U.S. state. Numerous universities and colleges offer agricultural science degrees in agricultural science classes. Degrees in additional sciences including: chemistry, biology, a related engineering specialty or physics may qualify individuals for agricultural science careers. Undergraduate coursework for food scientists usually consists of botany, biology, plant conservation and chemistry. Individuals preparing to become food scientists take courses such as food analysis, food engineering, food analysis, food processing operations and food microbiology. Individuals preparing to be plant and soil scientists take classes in soil chemistry, plant physiology, plant pathology, biochemistry and ento...
