Soy has essential amino acids, protein and is a good source of fiber and calcium. But, it turns out; soy also has the ability to naturally protect people from food-borne illnesses like listeria.
A new study from the University of Guelph has found soy can limit the growth of some bacteria, such as listeria and pseudomonas, and it does it better than chemical-based agents.
"Current synthetic-based, chemical-based anti-microbial agents kill bacteria indiscriminately, whether they are pathogenic or beneficial," researcher Suresh Neethirajan said. The body – and in particular, the intestines – need good bacteria to properly process the food we eat.The compounds in soybeans, however, do not kill off all bacteria, just the bad ones, Neethirajan said.
Soybean derivatives are already used in a variety of products including canned foods, cooking oils, meat alternatives, cheeses, ice cream and baked goods. Suresh Neethirajan, an engineering professor and director of the BioNano Laboratory at the university, said those with soy allergies need not worry about soy being used to prevent bacteria growth. He said their method isolates the active component of the soybean from the protein that causes allergic reactions. The soy isoflavones that are chemically similar to estrogen are also weeded out.
What is left is a compound that naturally stops the bad bacteria. Neethirajan said the problem with the synthetic additives that are currently used is that they can cause health problems.
"You do need good bacteria, beneficial bacteria, in our intestines to be able to properly process the food we eat, so that's why a lot of antibiotic food preservatives, which are made of synthetic chemicals, have ... side effects such as stomach cramps, diarrhea, bloating, gas," he said.
"Because of the selective specificity [by soy] towards inhibiting the pathogenic bacteria compared to beneficial bacteria, it will eliminate some of the health issues associated with the current synthetic-based food preservatives."
The research isn't just good news for those concerned about the additives to their food – it may also be a boon for soybean producers. Neethirajan is now working to identify which varieties of soybeans are best at preventing bacteria from growing.
"That way we could help the producers of soybeans to choose which varieties they want to grow towards specific end applications," he said. He is also working on a method to extract the specific components that involves "using water at very high pressure to be able to separate these … specific components, so it's very environmentally friendly from the manufacturing perspective."
Neethirajan's study will appear in the July edition of the journal Biochemistry and Biophysics Reports.

A University of Guelph bioengineering student has won the prestigious 2016 Sunnybrook Research Prize worth $10,000.
Robert Hunter beat out nine other finalists from across Canada. He presented his research on using biosensors for diagnosis, management and tracking of diabetes to a judging panel on Jan. 8, 2016 at the Sunnybrook Hospital of Toronto.
“My initial reaction was one of complete shock; there were a lot of great presentations from students from all over the country,” Hunter said.
“I didn’t think about it as a competition, more as a chance to share my work and ideas. This is the mindset I had going into it, so I felt very relaxed.”
The annual competition is intended to recognize excellence in undergraduate research and promote careers in biomedical research.
Hunter works in the University of Guelph’s BioNano Lab led by engineering professor Suresh Neethirajan. He plans to pursue graduate studies in bioengineering.
“Winning this prestigious and highly competitive Sunnybrook Research Prize is a remarkable achievement, and raises Guelph’s research profile at the national level,” Neethirajan said.
“This award will help Robert to continue to excel in academics and research. Enabling our students to get the best research experience at Guelph is truly rewarding.”
Hunter used microscopic materials to develop an inexpensive hand-held biosensor that rapidly detects diabetes in a user-friendly home test. It can distinguish between Type 1 and Type 2 diabetes from the same droplet of blood.
It’s the second year in a row that a Guelph student was named a finalist. Last year, Guelph student Evan Wright, who also works in Neethirajan’s lab, made the final round.

Up until recently, dairy farmers have been hindered in quickly detecting possible reasons for a reduction in milk production among their herd. One such reason is sub-clinical ketosis (SCK) when an affected cow appears to be well but only becomes observably under stress when SCK becomes full ketosis affecting major organs, or it could be other metabolic diseases. The only true method of detecting these abnormalities was by taking vials of the affected cow’s blood and sending samples to a lab for diagnosis. However, Bionanolab of the School of Engineering has advanced this procedure by putting the ability to diagnose a cow’s health in the hands of farmers themselves, thereby saving crucial time in detecting certain bovine metabolic irregularities, and thereby providing earlier treatment.
By detecting certain enzymes in blood, the newly developed device can pick out these biomarkers present in miniscule amounts and help identify diseases. A combination of the device’s unique composition of electrodes, a plant enzyme, and the correct amount of electric current were discovered by the Bionano research team to be the winning formula used collectively in the device known as a “Gryphsens”.
A New Tool on the Farm
Through the implementation of a hand held sensor, a dairy farmer can rapidly detect whether a cow has sub-clinical ketosis or other metabolic diseases through a small amount of blood being taken and having the sample analyzed in real-time through interfacing with the Internet by a smart phone. Such technology not only allows a dairy farmer to rapidly determine a cause for a reduction in milk production, but it also allows early detection of metabolic diseases that can then be treated, facilitating a cow to return to its normal milk volume levels in a shorter period of time. The cost saving of such early detection is substantial for small and larger dairy herds.
In the case of larger dairy herds, this Canadian invention that uses a unique electrochemical measurement of samples can be engineered for use with in-line robotic milking machines to monitor a herd individually, yet collectively, to avoid the repetitive and time-consuming method of testing each cow separately. The sensor, developed at Guelph’s Bionano laboratory of the School of Engineering by a team headed by Dr. Suresh Neethirajan is able to detect minute electrochemical activity in biological fluids that indicate biomarkers for certain irregularities and diseases. These markers flag slightly elevated levels of non-esterified fatty acids (NEFA), and a ketone prevalent in cows, β-hydroxybutyrate (BHBA), that at higher levels can both signal the early onset of ketosis and other metabolic diseases.
A Critical Time Line
Historically, the calving period is a stressful time for cows, described as a time of negative energy balance (NEB), when the onset of ketosis or other metabolic diseases are most prominent. Although the levels of NEFA and BHBA are miniscule at the beginning, early detection can reduce complications and a faster recuperation period, otherwise a later detection could lead to fatty liver, ketosis, displaced abomasum (twisted stomach), and inflammation of the uterus or a retained placenta. Dairy farmers are highly cognizant that charting a cow’s NEFA and BHBA levels is the litmus test for the animal’s overall health. One of the great advantages of testing for on-farm dairy cow diseases using our developed biosensor is that it not only significantly reduces the stress on the animals due to relying on a drop of blood instead of vials sent, but also provides instant test results.
The Lab Comes to the Barn
Traditionally, these levels are determined through expensive and lengthy tests performed in laboratories. Through electrochemistry and nanotechnology the University of Guelph’s Bionano team has made it possible for dairy farmers from all scales of operation to ascertain for themselves their herd’s health. Although humans have similar devices for measuring glucose levels for diabetes, the cow’s organism presents a further challenge by having 11 major blood groups versus four. The challenge was developing the sensor’s electrode that could simultaneously detect both NEFA and BHBA in variable metabolic conditions that can include a number of interfering components, which could alter the test results. Ability to detect multiple disease biomarkers from just a droplet of blood sample that could be used by untrained farmers is unique.
A Plant with the Answer
An issue the University of Guelph team had to surmount was the insulating property of GO that hindered the electrochemical function crucial for the biosensor. A particular enzyme from the soybean plant was integral in solving this problem and was incorporated into the dual electrodes. Although lipoxygenase is found in animal and plant species, using soybean lipoxygenase-1 (SLO) was itself a first for catalyzing direct electrochemical oxidation of NEFA in conjunction with graphene oxide nanomaterial. The result is a biosensor that has a dual function of detecting NEFA and BHBA in less than a minute on-site by the dairy farmer using a small sample of whole blood. Dairy cattle are an investment that must be kept in prime condition to maintain optimal production levels, and the Canadian biosensor is the latest tool for dairy farmers and large scale operations to monitor the health of their herds. The dual sensor can be an important part of routine screening used by farmers in the dairy barn.
