Novel composite antimicrobial film could take a bite out of foodborne illnesses

January 19, 2020

A novel composite film — created by the bonding of an antimicrobial layer to conventional, clear polyethylene plastic typically used to vacuum-package foods such as meat and fish — could help to decrease foodborne illness outbreaks, according to researchers in Penn State’s College of Agricultural Sciences.

Foodborne pathogen sheltered by harmless bacteria that support biofilm formation

August 21, 2019

Pathogenic bacteria that stubbornly lurk in some apple-packing facilities may be sheltered and protected by harmless bacteria that are known for their ability to form biofilms, according to Penn State researchers, who suggest the discovery could lead to development of alternative foodborne-pathogen-control strategies.

Whole genome sequencing may help officials get a handle on disease outbreaks

August 7, 2019

In a series of studies, researchers showed that whole genome analysis can provide highly detailed information on pathogens in a timely fashion. The findings could help public officials prepare treatment and prevention options when disease outbreaks threaten the public.

Novel powdered milk method yields better frothing agent

July 23, 2019

A novel method of processing — using high-pressure jets to spray milk and then quickly drying the spray — yields skim milk powders with enhanced properties and functionality, according to Penn State researchers, who say the discovery may lead to "cleaner" labels on foods.

Sensing food textures is a matter of pressure

June 13, 2019

Food's texture affects whether it is eaten, liked or rejected, according to Penn State researchers, who say some people are better at detecting even minor differences in consistency because their tongues can perceive particle sizes.

Building starch backbones for lab-grown meat using Lego pieces

March 26, 2019

A new technique to spin starch fibers using Lego pieces could have future applications for lab-grown "clean" meat, according to a team of food scientists from Penn State and the University of Alabama.

Avocado seed extract shows promise as anti-inflammatory compound

March 12, 2019

An extract from the seeds of avocados exhibited anti-inflammatory properties in a laboratory study, according to Penn State researchers, and it represents a potential source for novel anti-inflammatory compounds that could be developed as a functional food ingredient or pharmaceuticals.

More scrutiny needed for less-deadly foodborne bacteria

February 13, 2019

Employing advanced genetic-tracing techniques and sharing the data produced in real time could limit the spread of bacteria — Bacillus cereus — which cause foodborne illness, according to researchers who implemented whole-genome sequencing of a pathogen-outbreak investigation.

Wake up and smell the coffee: Research shows freezing beans can preserve aroma

January 15, 2019

As a food science major in Penn State's College of Agricultural Sciences, Andrew Cotter conducted research on the storage of coffee beans. He showed that storing roasted coffee beans in the freezer — a popular preservation method — can help preserve the aroma of certain varieties of beans.

A 'bran' new way to preserve healthy food with natural ingredients

January 3, 2019

A natural antioxidant found in grain bran could preserve food longer and replace synthetic antioxidants currently used by the food industry, according to researchers at Penn State.

Chewing gum may be effective for delivering vitamins

October 9, 2018

Nearly 15 percent of all chewing gum varieties sold promise to provide health-enhancing supplements to users, so Penn State researchers studied whether two vitamin-supplemented products were effective at delivering vitamins to the body. Their results validate the concept of gum as an effective delivery system for at least some vitamins.

Link found between bitter-taste sensitivity and cancer risk

July 18, 2018

High bitter-taste sensitivity is associated with a significantly increased risk of cancer in older British women, according to researchers who conducted a unique study of 5,500 women whose diet, lifestyle and health has been tracked for about 20 years.

Cocoa bean roasting can preserve both chocolate health benefits, taste

April 4, 2018

Manipulating the temperature and the length of time under which cocoa beans are roasted can simultaneously preserve and even boost the potency of some bioactive and antioxidant compounds while protecting desired sensory aspects of chocolate, according to Penn State researchers.

Research aims to help cacao producers, chocolate makers boost profits

February 15, 2018

Craft chocolate — made with fine flavor cacao beans and valued for its distinctive flavors and high quality — is gaining a fast following, and research underway in Penn State's College of Agricultural Sciences is aimed at helping bean growers and bar makers benefit from this trend.

Using a pig model to study chronic diseases may help minimize drug failure rate

July 24, 2017

Scientists may be able to minimize the failure rate of drugs for diseases linked to high-calorie diets, such as colon cancer and type 2 diabetes, if they test treatments using a pig model, according to an international team of researchers.

Grape-based compounds kill colon cancer stem cells in mice

June 19, 2017

A compound made from grape skins and grape seeds killed colon cancer stem cells in mice, according to researchers. The study, along with previous studies on the low incidence of colon cancer in populations that tend to eat plants, may also offer clues to the role that foods play in suppressing and treating cancer.

Invent Penn State’s Fund for Innovation awards $75,000 to Persea Naturals

May 5, 2017

A team of food science researchers from Penn State College of Agricultural Sciences are launching a promising new venture to produce a line of all-natural, vibrant food colors, dubbed AvoColor, using a compound derived from the seed of the avocado.

Ingesting soy protein may ease severity of inflammatory bowel disease

April 26, 2017

A diet supplemented with soy protein may be an effective adjunct therapy for inflammatory bowel diseases, Penn State researchers reported after completing a study that included mice and cultured human colon cells.
