U of Minnesota Food Science News Fall 2011

Posted on:January 11, 2012


Gary Reineccsius, Food Science and Nutrition department head, U of Minnesota

In a newsletter, the University of Minnesota’s head of the Food Science and Nutrition Department, Gary Reineccius, PhD, covered topics from a new natural peptide that can kill gram-negative pathogens in food to student enrollment figures.

Food scientists, in general, remain more connected to universities and colleges than many professions, I think. Much (maybe most) technical expertise is learned from experience over a food technologist’s career, however, generally those careers start with formal degrees. The three arenas of government, industry and academia all have a huge impact on the world of food science and product development.

I myself stay somewhat connected with the University of Minnesota’s Department of Food Science and Nutrition (FScN). Despite the many years that have passed, personal connections remain, including with the department chair, Dr. Gary Reineccius, who was my flavor chemistry professor. I also keep tabs on the “going ons” at FScN in that it also provides source of information into the world of product development.

FScN’s 2011 fall newsletter had a few points I found of interest. They include:

  • Student enrollment in food science is up, but pales in comparison to registration in the nutrition. The department has some 100 students in food science (Reineccius believes food science was down to about 37 students at one time). Enrollment in the nutrition program (which is distinctly different from the food science program) is stable at about 360 students. Lastly there are about 130 graduate students in each of those two disciplines.
  • The department obtained approval from the University’s office that manages research for a Master Agreement for Service and Research. Reineccius notes that ownership of intellectual property (IP) and publication rights are major stumbling blocks in establishing research contracts [a key source of funding for universities]. Furthermore, Reineccius considered it good news that the University now has a program (  that, in exchange for a “reasonable upfront payment,” will forgo any consideration of intellectual property (IP) rights. “Basically, the University is recognizing that little is gained in royalties and much is lost in not working with industry when appropriate.”
  • Lastly, the newsletter carried an example of the type of research that the industry may be interested in. In August 2011, university researchers discovered and received a patent for a naturally occurring lantibiotic, a peptide produced by a harmless bacteria, that could be added to food to kill pathogens such as Salmonella, E. coli, and Listeria. The newsletter states “The lantibiotic is the first natural preservative found to kill gram-negative bacteria…  The lantibiotic could be used to prevent harmful bacteria in meats, processed cheeses, egg and dairy products, canned foods, seafood, salad dressing, fermented beverages, and many other foods.” The newsletter added that besides food safety benefits, “lantibiotics are easy to digest, nontoxic, do not induce allergies, and are difficult for dangerous bacteria to develop resistance against.”

10 Food Top Trends Lists for 2012

Posted on:January 6, 2012

I always like sitting back as trend predictions for the coming year roll in.  While each one can be insightful, when they are considered together (especially if from unrelated sources), larger themes emerge.
A few disclaimers on the following list of lists include that they tend to be Europe and North American “centric.” Secondly, although I numbered the lists, the rank is arbitrary and not meant to reflect their quality or importance. Lastly, more 2012 food trend lists have been published.  If you feel I missed a nice one, send me a note at:

1. Leatherhead Food Research’s 10 Food Trends

Trend #14 – Three Cautionary Trends
  • Misuse of words like “artisan” and “heirloom” and “local” will pollute their meaning, especially as chains co-opt them for marketing slogans. Adding a whole grain to factory bread doesn’t make it “artisan” and not all misshapen tomatoes are “heirlooms” from “local” growers. “Green” and “sustainable” fall into this category, too.
  • There’s a looming oversupply of farmers markets.
  • Too many chefs are smoking too many foods.

Why is There So Much Sugar in our Foods?

Posted on:January 5, 2012
People like sweetness cats cannot taste sweetness

Food processors add sugar to foods because people like sweetness. Sugar is not added to cat food because cats cannot taste sweetness.

I was once asked in a Public Radio interview “Why do food processors put so much sugar in processed foods?” The answer is fairly obvious, but I’ll get to that in a moment.

As a group, perhaps no ingredient category has been as maligned in recent years as those ingredients that make foods and beverages sweeter. From table sugar (sucrose) to aspartame, from high fructose corn syrup (HFCS) to sucralose, many ingredients that add sweetness have been the target of consumer pressure groups to diet plans.

Unlike the other four tastes (saltiness, bitterness, sourness and umami), the preference for sweet tasting foods is innate in humans and many mammals. Even hours-old newborns show pleasure and a preference for sweet tasting products(1,2,3). For example, in a study by researchers J.A. Desor and others, babies less than 84 hours old drank more water sweetened by lactose, sucrose (sugar), glucose or fructose in a three minute period than they did plain water.

It has been theorized that the ability to taste (and like) sweetness gave a survival advantage in that sugars found in fruits, for example, provide a quick energy source. The ability to taste sweetness is genetically based but is not universal among mammals, by the way. The family cat and other members of the Felidae family (tigers, leopards, lions) cannot taste sweetness(4). It has been theorized this was important in their development as carnivores. Also, certain ingredients may taste sweet to some animals, but not to others. Old World monkeys and primates such as baboons can taste that aspartame (NutraSweet) is sweet. However, New World monkeys such as the howler and spider monkeys do not perceive that aspartame is sweet.

This is not to say that people don’t differ in how much they like sweet foods. To some, salty snacks may be more appealing; however, we likely all know people with “sweet tooths” who never saw a confectionary that they didn’t like.

As obesity continues to grow in concern around the world, food manufacturers have responded by adding less sugar or switching to low calorie sweeteners in their products. No-sugar cereals are sold in the marketplace, for example.

However, why do food processors put sugar (or any sweetener) in a food or beverage? Because we like it!

Developing Processed Foods for Emerging Economies

Posted on:January 3, 2012

Water scarcity is an issue in many emerging economies. Developing bottled beverages for these markets will present unique challenges.

I was watching an interview with Indra Nooyi, CEO and President of PepsiCo on CNBC yesterday. Like many other consumer goods companies, the food industry has focused a great deal of attention on potential market opportunities in emerging economies. However, the program relayed solemn reminders that producing and marketing packaged consumer foods and beverages to relatively poor and populous nations cannot be “business as usual.”

A recent United Nation report predicted that in 2030 or perhaps even earlier, India will surpass China (excluding Hong Kong) as the most populated country on the planet. The two countries will “meet” at a population of about 1.45 billion people each.

The CNBC program went on to say that bottled beverage companies are being criticized in that they are encouraging the consumption of a product that requires the use of a scare and thus valuable commodity in its manufacturer…water. That is, more than one liter of water is required to produce one liter of a soda. Nooyi replied something along the lines that she understood the concern in that she grew up in one of the most water-deprived region of India. She told the story that everyone would be rationed “three buckets” of water and they would have to decide how to use it…to drink it, launder clothes with it, bath in it. Even today if she took a shower more than two or three minutes, she fought feelings of guilt.

Should food manufacturers thus not pursue such markets? I myself believe that responsible companies will find a way to serve consumers while developing innovative ways to maximize and not squander scare resources. When I worked for Orval Kent Foods, we had plants with similar equipment making the same products in New Jersey, Chicago and the Los Angeles area. The Los Angeles plant, however, used a fraction of the water that the other the plants did. Water was and is scarce in California. Cleaning regimes and other plant practices had evolved to do more with less.

The need to find innovative ways to maximize scare resources should not be a burden,  but a creative challenge for which both companies and their customers will be rewarded.

Formulating Fiber into Foods and Beverages

Posted on:October 23, 2011
Researchers have found fiber in brewed coffee

Using a specific analytical procedure, Spanish reseachers have found soluble fiber in coffee. Depending on testing procedures, perhaps dehydraded coffee can be a source of fiber.

The health benefits of fiber are many. Although benefits differ as to whether a fiber is soluble or insoluble, the benefits range from decreased risk of cancer, cardiovascular disease and diabetes to laxative effects and ability to more easily maintain weight.

Generally speaking, fiber is defined as plant material that is resistant to hydrolysis by the endogenous enzymes of the mammalian digestive system. That is, humans can not digest it. One soluble fiber, chitosan, is commonly derived from exoskeleton of crustaceans, such as shrimp and crabs, and is sometimes called an “animal fiber.” It is sold as a dietary supplement in North America.

Fruits, vegetables, whole grains and pulses (such as chickpeas, beans) are excellent health foods and can sometimes be a good source of dietary fiber. However, as the food industry strives to develop better-for-you processed foods, there is interest in finding ways of enhancing the fiber content of many different kinds of foods.

Ingredient suppliers provide a broad range of products for the fortification of food. Examples include brans from the hulls of grains to other sources such as peas, fruit, sugar beet and bamboo fiber to name just a few. One commercially available sugar beat fiber, for example, contains some 73 percent TDF (total dietary fiber) in the form of hemicellulose, pectin, cellulose and lignin. Pea fiber can be over 90 percent TDF and soy fiber is typically 75 to 80 percent TDF.

When suppliers purify and modify fiber, blander, more colorless ingredients are created and the percent of TDF can be increased. For example, powdered cellulose can be up to 99 percent dietary fiber.

“New” and sometimes surprising sources of fiber are also being discovered. For example, coffee beans themselves are rich in dietary fiber. However, two Spanish researchers using a method involving enzymatic treatment plus dialysis discovered that brewed coffee (and thus potentially dehydrated instant coffee) contains 0.47 to 0.75g soluble dietary fiber per 100ml of coffee 1. This is more than many orange juices, for example.

The following chart provides ways fiber can be added to foods. The fiber from different sources all add up in a formula. Thus, while cinnamon packs a powerful flavor punch, it is more than half fiber and can contribute at least some fiber to the total fiber content of a finished product.

If anyone has other favorite ingredient sources of fiber, just let me know and I can add them to the list.

Ingredient Percent TDF
Corn bran, crude 79.0
Cinnamon, ground 53.1
Wheat bran, crude 42.8
Chia seed 34.3
Cocoa, powder 33.2
Flaxseed 27.3
Black Pepper (spice) 25.3
Rice bran, crude 21.0
Bulgur, dry 18.3
