Many times we are asked, “Why should we use soy proteins in their processed food products and blended protein beverage and bar solutions?” One of the very best reason is price stability over the long term.
In recent years, we have seen the prices of WPC/WPI and Caseinates/MPCs soar
above their historical average prices by 50 to 60% . All these milk based proteins are subject to global and domestic effects on the producing country’s supply and demand for fluid milk for retail dairy products including fluid milk and cheese as well as conversion into butter and skim milk powder or caseinates/milk protein concentrate powders. In addition, strong demand for Whey proteins have resulted in long leadtimes and short supply while dairy companies try to balance out their cheese production against this demand. Although present prices appear stable, milk-based proteins remain volatile to any supply versus demand imbalance.
In contrast, isolated soy protein (90% protein) and soy protein concentrates (65% protein) are very price stable. The prices for isolated soy proteins has remained stable only increasing due to subtle soy crop-related changes, capital improvement,energy,labor and transportation and inflation while at the same time improving in flavor, quality and improved functionality. (Over the past three decades, the average cost of domestically produced soy isolates has increased only 2.5% per year.)
A primary reason for this price stability is that 85% of world’s soybean production is crushed into soybean oil and meal. Of the meal,98% is converted into animal feed and only 2% is further processed into soy flour and proteins. With a bountiful supply of raw material, soy protein shortages and price spikes are rare.
As we develop the nutritious foods of the future and consider the positive nutritional and physiological value of blended proteins, let us recall the most price stable of all: Soy protein.
Most formulators and nutritionists realize that soy protein provides many functional and nutritional benefits in foods. These benefits include providing better yields and moist texture in processed meats and protein-based satiety when added to beverages or nutrition bars. However, in all cases, when added to prepared foods or nutritional products, soy is considered a definite allergen as it is listed as one for the 8 top allergens found in foods as follows:
- Tree Nuts
All of us are concerned about the labeling and health concerns of having an unwanted allergen in our product. But here are some facts which might help us to re-consider soy protein use:
- The largest survey conducted found only 0.0005 percent of adults are allergic to soy protein.1
Cow’s milk allergy is about 40 times more common than soy allergy.1
- The American College of Allergy, Asthma and Immunology estimates that only 0.4 percent of children are allergic to soy protein. Of those, an estimated 70 percent will outgrow their allergy by age 10.2
When designing a prepared food or nutritional food for adults, it is vital to weigh whether our soy protein use or rejection is based on allergen labellling dictates or remote risk concerns about allergenic effects of soy protein products.

We hope you had the opportunity to attend at least one of the premier events SCIFTs put on in Anaheim, CA this March. This was the 30th anniversary of these events and it was one of the best. The Conference held the first half of the day was a wealth of information on topics of interest for the busy Food Industry professional. Highlights included the esteemed Elizabeth Sloan, PhD of Sloan Trends, giving a ‘sneak peek’ of her market insights on 2017-2018 food trends. Look for her full report to be published in IFT’s Food Technology magazine soon.
Other speakers and subjects included: insights from Debra Topham, MS, CNS, CFS on managing the new nutrition label changes set in place in 2016, Katie Wagner, founder of Katie Wagner Social Media, on how food industry professionals can harness the power of social media to engage our audience, build credibility and get our message out, Dr. Ash Husain discussed scientific advancements in sterilization processes for food safety, and we heard from Dan Solis, MHA FDA with updates on regulations and processes in food import and exports. Overall, it was very informative day.
In addition to the knowledge and expertise of the speakers, 5 student teams from Southern California Universities participated in the annual Student Product Development Competition. The teams utilized the conference theme: New World, New Tools to present their ideas to the panel of judges.
And last, but certainly not least – the day was capped off with the SCIFTs Suppliers’ Night hosted in the ballroom of the Disneyland Hotel. The event was sold out – vendors, customers, and students were able to meet with manufacturers and distributors of a wide variety of ingredients. The evening was capped off with a complimentary hors’ de oeuvre reception. If you did not attend, we encourage you to put next year’s event on your calendar – March 7, 2018.
When I first started selling soy protein in 1996, I had to learn what protein quality was. In the old days we used PER – a measure of the effectiveness for protein to maintain health in rats. I am sure mothers around the world would have been comforted in knowing that the nutrition of their infant formula was based on what a baby rat needs – not a baby human. In the 80’s & 90’s a new protein quality measure was emerging, this one called PDCAAS – it measures the amino acids needed by humans and is based on the needs of preschool aged children. It remains the standard measure for protein quality today.
Amino acids are the building blocks of protein, protein is the building block of the human body, there is a minimum amount of specific, what we call “essential,” amino acids required for our bodies to function and remain healthy.
PDCAAS measures the essential amino acids present in protein sources to indicate protein quality. Egg is a perfect protein. Milk based products like whey protein and casein are perfect proteins.
Soy is a perfect protein.
Please remember, proteins are groups of amino acids and most foods contain protein. It’s just that not all proteins have all the essential amino acids.
Below are some common PDCASS values:
Whey Protein 1.00
Whole Egg 1.00
Soy Protein 1.00
Beef Protein 0.92
Pea Protein 0.88
Yes, we really listened to food safety music! Every year we support the Northern California IFT section’s joint event with the UC Davis Food Science Department. We love sponsoring food science students and having the opportunity to talk with them over dinner.
This year’s event was one of the most entertaining IFT events we have ever been to! Instead of a speaker, we were thrilled to listen to Food Safety Music, performed by Dr. Carl Winter’s hilarious and educational food safety music parodies.
We loved hearing “You gotta wash your hands” (Sung to the tune of the Beatles “I wanna hold your hand”), but I think the favorite was “We are the microbes” (we are the champions).
The whole evening was perfect and the songs appealed to students, professors and industry members alike!
At SPI Group, we are strong supporters of local IFT events – and we may have just been to our favorite events with the Alamo IFT section! We loved going to Johnson Space Center in Houston, TX to hear Dr. Shannon Walker discuss her experience with long duration space flight.
Dr. Walker described how she trained at the Cosmonaut training center in Russia, using training suits that weigh a couple of hundred pounds! They do their training in large pools where they will spend 6 hours underwater. After 3 years of training, Dr. Walker went to the International Space Station where she spent 6 months living and working. She said that one thing that she loved was seeing 16 sunrises and 16 sunsets every day, since the International Space Station orbits the earth once every 90 minutes. She showed us her many photos taken from space including hurricanes and spectacular shots of Northern and Southern lights.
Since we are food scientists, we of course asked her about the food! She told us that there are approximately 200 different foods and beverages in the International Space Station pantry. The foods are mostly soft and have to stick together – the main issue is that the food can not have any crumbs at all since the crumbs could get in to the space station filter system. She told us that they have to add salt and pepper in a liquid form, from a dropper bottle!
We were fortunate enough to tour both the Space Food Research Center at Texas A&M university, where they make retorted pouches, as well as the food lab at Johnson Space Center. Contact us for more details and photos of space food!
Psyllium is a soluble fiber made from the seed husks of the Plantago ovata plant. It’s considered a soluble fiber and helps move food through the digestive system so that your body can break it down and convert it into essential nutrients. Without enough fiber in a person’s diet to help move food though the gut will adversely affect gut bacteria, making it harder to metabolize and absorb the nutrients.
The fibers purely mechanical function is absorbing water. It does this in a person’s large intestines when used as a laxative and is the bulk forming fiber in laxative products like Metamucil. 60% of psyllium is used for applications dealing with digestive health.
Psyllium not only alleviates many digestive conditions but also aids in supporting lower cholesterol by decreasing lipid levels and lowering blood sugar levels. Psyllium promotes a healthy heart by lowering blood pressure and strengthening heart muscles. When the fiber forms a gel, it slows down the uptake of fats and sugars from the food, causing blood sugar and cholesterol to rise more slowly after a meal.
One study shows that at least 6 weeks of daily psyllium intake is an effective way for people who are obese or overweight to control their cholesterol and blood sugar levels with very few side effects.
In the food industry psyllium fiber is used as a thickener in ice cream and frozen desserts. A 1.5% volume by weight ratio of psyllium mucilage exhibits binding properties that are superior to a 10% volume by weight ratio of starch mucilage.
The viscosity of psyllium mucilage dispersions is relatively unaffected between temperatures of 68 and 122 degrees Fahrenheit, by pH between 2 and 10 and by salt concentrations of up to .15 ppm.
These functional properties of Psyllium make it an excellent source of natural dietary fiber and may lead to and increased use the food industry. If you have any questions about psyllium or any dietary fibers please contact your SPI Group sales rep for more information on psyllium and the other fibers SPI Group distributes.
The first Earth Day was April 22, 1970. It was organized in response to population growth with an eye toward the impact every human makes on the Earth. Denis Hayes, the chief organizer of the first Earth Day said at that time, “It is already too late to avoid mass starvation.”
The FAO and the UN predict global population to reach 9 Billion by 2050, this means we will need to to increase food production by 70%. Demand for protein (an essential nutrient for growth and health) is expected to rise between 50 and 90% assuming developing countries continue to consume low end quantities of 25 grams of protein per day per person and developed countries consume 50 grams of protein per person per day.
In the USA, 50% of consumers have a goal consumption of protein per day. 87% know that protein builds muscle, 72% know it can help you feel full, and 63% know it is an essential part of weight loss programs.
These statistics prove that whether you’re feeding hungry populations or educated segments, the demand for protein will continue to grow, straining our resources and causing prices to rise and supply to tighten. This blog is the first in a series titled, Creating Protein Strategy. Each month we will discuss different considerations in your creation of a protein strategy, and we will highlight how soy protein is a key element in many ways. But this is not just about soy. It’s about diversification, flexibility, nutrition, flavor, safety and environmental impact. Reduce your reliance on one protein and hedge your strategy to create a strong protein platform for your company’s future and the future of our planet.

Most meat processors are dealing with cleaning up their labels while battling with pathogen and spoilage control in their RTE deli products. Because of the need for additional hurdles to protect against pathogens, proven antimicrobials like lactates and diacetates are used in combination with high pressure pasteurization. (HPP). These hurdles have their side effects. High levels of lactates and diacetates can produce an off-flavors and HPP is very costly.
Microbial fermentations have been used for centuries in the preservation of foods with beneficial organisms. Cheese(milk),salami(meat) and sauerkraut(cabbage) are example of microorganisms helping to preserve these foods by acidification,competitive exclusion of unwanted organisms, or the production of metabolites which are detrimental to growth of pathogenic and spoilage organisms. By using the technologies resulting from the development of friendly organisms for foods, manufacturers like Dupont were able to make and to gently collect and concentrate the valuable metabolites,peptides and organic acids needed to preserve products at very low and affordable usage levels. The primary family of products based on cultured dextrose from Dupont is called MicroGARD and are widely used in many culinary and bakery applications like soups and sauces and refrigerated entrees.
However the greater challenge in RTE cooked meats was the need for both pathogen control(primarily Listeria montogenes (Lm) control) and protection in shelf life against a myriad of spoilage organisms. In order to meet this challenge, the Dupont Food Protection scientists came up with a unique solution combining several technologies. First, they designed a fermentate which was broad spectrum in its spoilage organism protection with a special emphasis against lactic acid formers like Leuconostoc. Secondly, they assured an additional hurdle of Lm protection with the addition of a buffered vinegar powder. Challenge studies and commercial use of this combined product named BioVia CL600 have shown it to be highly effective when used at 0.75 to 1.5% without flavor or textural problems.
