Enhancing Safety and Adding Flavor: The Role of Additives in your Food Supply

Last week, I ran across a post on Facebook from a childhood friend denouncing additives in the food supply. I had to quickly scroll by, otherwise I may have been tempted to dispute the facts of the post. I realized that no matter how long I had known this individual, I was never going to change their mind about the important role some food additives play in the safety and flavor of our food on social media. But it did cause me to want to address food additives in the blog post this month.

Over the years, the shopping habits of the average American has changed drastically.  Because of this, our demand for shelf life has increased, which has impacted the additives that are used in our food. This also impacts the food we purchase in our foodservice operations. Combined with this shift, our economy has transitioned from the agricultural society we once were, focusing much more on services, technology, and manufacturing. While this isn’t a bad thing, it does mean that fewer and fewer American’s truly understand our food supply and where our food comes from.  Few have grown up on a farm or worked in agriculture, leading to questions about things such as additives and the role they really play in our food.

So, what is a food additive? According to the Food and Drug Administration (FDA), a food additive is “any substance the intended use of which results or may reasonably be expected to result, directly or indirectly, in its becoming a component or otherwise affecting the characteristic of any food.” The FDA is responsible for approving any new food additive that is not yet recognized as safe, and these additives are more strictly studied and regulated today than any other time in our history.

A food additive is generally considered safe for its intended use if the amount an average consumer would consume daily of the additive is less than, or approximates, the acceptable daily intake.  The acceptable daily intake is the amount that can be consumed on a daily basis for a lifetime without risk to the individual, and these amounts are based on human and animal studies.


Consumers today demand convenience without compromising on safety or quality. Food additives enable manufacturers to meet these demands by providing products that are convenient, long-lasting, and safe.


Once a food item has been recognized as safe, it can be added to the GRAS (generally recognized as safe) list, officially known as the GRAS Substances Database.  You will find many different substances on the list – many of which are likely very familiar to you, such as Sodium Chloride (table salt) and garlic. But you will also find those less familiar, such as Thiamine hydrochloride, which is used as a flavor enhancer and can be used to increase vitamin B1.

From preserving freshness to enhancing flavor and texture, food additives are an important tool for manufacturers to provide the product we find appealing and to help ensure the safety of the product. Antioxidants, such as vitamin C and tocopherols, help delay the onset of oxidation, which causes fats and oils to become rancid. Lecithin isn’t just a releasing agent, it can also be used to help with emulsification, improve texture and mouthfeel, and extend shelf life.

Food additives are also vital for food safety.  Preservatives and antimicrobial agents help mitigate food safety risk by inhibiting the growth of bacteria and pathogens. For example, nitrates and nitrites are commonly used in cured meats to prevent the growth of Clostridium botulinum, the bacterium responsible for botulism. Citric acid and acetic acid are used to adjust the pH of foods, creating an environment that inhibits the growth of bacteria and prolongs shelf life. Sulfur dioxide is used in dried fruits to prevent microbial spoilage. By utilizing these additives in their formulation, manufacturers can reduce the likelihood of microbial contamination and help protect the public health.

Consumers today demand convenience without compromising on safety or quality. Food additives enable manufacturers to meet these demands by providing products that are convenient, long-lasting, and safe.

I would be remiss if I led you to believe that they are safe no matter how much is used. As I noted earlier in this blog, the additives are approved based on the acceptable daily intake.  Thus, it is imperative to stress the importance of using additives judiciously and responsibly, adhering to regulatory guidelines and safety standards to protect public health and well-being. Risk Nothing. 

Protecting Fresh Produce Post-Harvest, Integral to Safe Food

During the height of the summer, at least in the Midwest, farmers markets are in full swing and fresh produce is plentiful. Every backyard gardener is reaping the benefits of their work, with bountiful harvests of tomatoes and cucumbers. Everyone seems to have a neighbor who is trying to pawn off his or her over-production of cucumbers or summer squash during this time of year.  When picking up that produce at the farmer’s market or from your neighbor down the street, have you ever given any thought to the microbial safety of it?  Honestly, even in my position, it certainly is NOT the first thing that comes to my mind.  But, earlier this month, I came across a news story out of Wisconsin discussing a Salmonella outbreak associated with shelled peas sold at a local farmers market. Who would have thought shelled peas would be impacted?  The story noted, and it served as a great reminder, that most outbreaks associated with Salmonella in produce are due to mistakes made in handling or transportation of produce after harvesting.

Properly Cleaning and Sanitizing: The Right Chemical Mix to Maintain Ultimate Effectiveness

A few weeks ago, my family and I had the pleasure of setting sail on a cruise vacation. It is truly one of the only ways that I find that I am able to unplug from work and relax for a small spell. However, as I walked around the ship in our post-COVID world, I couldn’t help but admire all the extra cleaning steps the staff were undertaking to keep us all as safe as possible while in the middle of the ocean with 3,000 other vacationers. All of this cleaning and sanitizing had me thinking about how we each clean and sanitize our own operations and which chemicals we chose to use.

Proper Cooking Temperature: A Basic Food Safety Measure

Each summer, we see an increase in the incidence of foodborne illnesses. Perhaps this is because of the warmer temperatures making temperature control for Time/Temperature Control for Safety (TCS) food more difficult or perhaps it is the increased amount of people who are barbequing this time of year – it is National Picnic Month, after all!

Changing Climate: The Unseen Impact on Food Safety

In June, I was asked to participate in the Allinfoodz podcast, put on by a colleague, Dr. Amit Sharma, at Penn State University.  One of the points Dr. Sharma wanted to discuss was the impact of climate change on food safety, which is something I was certainly aware of, but not something I had done much research on.  However, when preparing for the interview and podcast, it was interesting to learn more about the relationship between the two.
