Antibacterial Polymer Offers Promise in Reducing Risk of Cross Contamination

A new antibacterial infused polymer offers promise for reducing the risk of bacterial contamination during the production of processed ready to eat foods.
"Effectiveness of SymbiCoat Antibacterial Coating to Reduce Listeria Monocytogenes" was among the topics discussed last week in Winnipeg as part of Prairie Livestock Expo.
Dr. Claudia Narvaez Bravo, an Assistant Professor in the Department of Food and Human Nutritional Sciences at the University of Manitoba, explains the product, developed by Exigence Technologies, is an antimicrobial polymer.

Clip-Dr. Claudia Narvaez Bravo-University of Manitoba:

It can be used to coat or cover surfaces like food contact surfaces, for example stainless steel which is quite common in the food processing environment.
Once we coat that surface and you activate the surface with chlorine, which is a 150 PPM solution, which is water an chlorine, then you activate that surface.
Let's say that you have Listeria Monocytogenes in that environment that coating will kill it and it will prevent that bacteria from transferring from that surface to the food.
The coating basically was developed to minimize the risk of cross contamination in that processing environment, mainly in ready to eat products when you have a killing step like, cooking and then you have to package.
Normally that's when contamination happens.
This is an alternative to have more control in the environment to kill this kind of pathogen.

Dr. Narvaez Bravo says the product is still undergoing regulatory approval but  independent lab scale testing conducted by the University of Manitoba has shown it to be very effective.

The Investment Opportunities of Industrial Hemp

Video: The Investment Opportunities of Industrial Hemp

The fledgling U.S. hemp industry is decades behind countries like Canada, France and China, but according to impact investor and this week’s podcast guest, Pierre Berard, it could flourish into a $2.2 billion industry by 2030 and create thousands of jobs.

To reach its potential, what the hemp industry needs most right now, Berard said, is capital investment.

Last month, Berard published a report titled “Seeing the U.S. Industrial Hemp Opportunity — A Pioneering Venture for Investors and Corporations Driven by Environmental, Social and Financial Concerns” in which he lays out the case for investment.

It’s as if Berard, with this report, is waving a giant flag, trying to attract the eyes of investors, saying, “Look over here. Look at all this opportunity.”

Berard likens the burgeoning American hemp industry to a developing country.

“There is no capital. People don’t want to finance. This is too risky. And I was like, OK, this sounds like something for me,” he said.

As an impact investor who manages funds specializing in agro-processing companies, Berard now has his sights set on the U.S. hemp industry, which he believes has great economic value as well as social and environmental benefits.

He spent many years developing investment in the agriculture infrastructure of developing countries in Latin America and Africa, and said the hemp industry feels similar.

“It is very nascent and it is a very fragmented sector. You have pioneers and trailblazers inventing or reinventing the field after 80 years of prohibition,” he said. “So I feel very familiar with this context.”

On this week’s hemp podcast, Berard talks about the report and the opportunities available to investors in the feed, fiber and food sectors of the hemp industry.

Building an industry around an agricultural commodity takes time, he said. According to the report, “The soybean industry took about 50 years to become firmly established, from the first USDA imports in 1898 to the U.S. being the top worldwide producer in the 1950s.”

Berard has a plan to accelerate the growth of the hemp industry and sees a four-pillar approach to attract investment.

First, he said, the foundation of the industry is the relationship between farmers and processors at the local level.

Second, he said the industry needs what he calls a “federating body” that will represent it, foster markets and innovations, and reduce risk for its members and investors.

The third pillar is “collaboration with corporations that aim to secure or diversify their supply chains with sustainable products and enhance their ESG credentials. This will be key to funding the industry and creating markets,” he said.

The fourth pillar is investment. Lots of it. Over $1.6 billion over seven years. This money will come from government, corporations, individual investors, and philanthropic donors.

The 75-page report goes into detail about the hemp industry, its environmental and social impact, and the opportunities available to investors.

Also on this episode, we check in with hemp and bison farmer Herb Grove from Brush Mountain Bison in Centre County, PA, where he grew 50 acres of hemp grain. We’ll hear about harvest and dry down and crushing the seed for oil and cake.
