The Positive Economic Value of Soy Protein in Prepared and Nutritional Foods

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.

 

 

The Great Protein Quality Opportunity

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

Casein                                                1.00

Soy Protein                                       1.00

Beef Protein                                     0.92

Pea Protein                                       0.88

Potato                                                0.74

Psyllium fiber: digestive and heart health, functional ingredient

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.

Shelf Life Naturally: Ingredients for Processed Deli Meats

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.

What Is Saccharomyces boulardii?

Saccharomyces boulardii from Ohly is a yeast based probiotic that balances the naturally occurring bacteria located in the intestines. It strengthens the intestinal immune system and restores normal bowel functions.

Saccharomyces boulardii both treats and prevents diarrhea. In cases of viral or bacterial types of acute diarrhea Saccharomyces boulardii acts to effectively treat the condition along with oral rehydration solutions.

During antibiotic therapy Saccharomyces boulardii also prevents diarrhea. Saccharomyces boulardii is the only probiotic with natural resistance to most antibiotics.

S.boulardii is one of the most studied probiotics available. It is a non-pathogenic yeast that maintains distinct taxonomic and physiological difference from Saccharomyces cerevisiae or brewer’s yeast.

Where Did Saccharomyces boulardii Come From?

Henri Boulard, a French microbiologist isolated a microorganism from the skins of lychee fruit in Indochina 1923. It was identified as a yeast and classified under the genus Saccharomyces and species Saccharomyces boulardii because of its physiological characteristics.

Key Benefits of Saccharomyces boulardii

Helps treat all kinds of diarrhea including antibiotic associated diarrhea

  • Helps treat Irritable Bowel Syndrome
  • Supports gut function against allergies, Crohn’s disease and Salmonella
  • Reduces bloating and gas
  • Lactose Free
  • Gluten Free
  • Suitable for vegetarian and vegan
  • Helps improve digestion

How is Saccharomyces boulardii produced?

Saccharomyces boulardii production is based on the following manufacturing processes:

  • Yeast fermentation
  • Separation of yeast from spent nutrients

Fluid bed drying process that removes extra and intracellular water from the yeast. The drying process allows for storage at room temperature and guarantees an optimal level of living cells when yeasts are rehydrated.

Saccharomyces boulardii from Ohly is manufactured to exacting and certified pharmaceutical standards. Manufacturing standards meet GMP requirements. It is freeze dried and strain verified through genetic typing to ensure maximum efficacy.

Applications for S. Boulardii include dietary supplements  (formulated in capsules or sachets), branded pharmaceuticals, pediatric health and animal feed/pet food. Contact us for more information!

How sustainable is soy?

SPI Group has been the home of many protein products over the years (whey, wheat, rice, pea, beef).  But our favorite has always been soy.  Why?  First it is sophisticated, we can use soy protein for nutritional or functional improvement in almost every food product.  Second, soy is a complete protein, with a PDCASS of 0.99 it contains all of the essential amino acids required for growth in infants and at risk populations.  Soy is an equivalent protein to animal protein for school food service and it costs less in-use.  Third, it is available.  Soybean use for food is 2-5% of the US crop meaning we can always expand how much humans consume.   This also means soy protein production is dependent on nothing, it is not a waste stream or intermediate product.  Soy protein comes from soybeans.  Straight up.

The last and most important reason that soy protein is important today is that we can grow more soy protein with fewer resources than any other complete protein source:

One acre of farmland can produce:

  • 20 pounds of beef
  • 78 pounds of eggs
  • 82 pounds of milk protein products
  • 356 pounds of soy protein

Why use rice starch?

 

There are many different types of starches that a formulator can use when developing a new product.  Today’s blog is going to feature one of our favorite starches:  rice starch! Here are a few things we like about rice starch:

Smallest granule size – rice starch has the smallest starch granule size (2-8 μm)., compared to other commercially available starches, such as corn starch.

Because of it’s small granule size, rice starch is excellent as a whitening agent and smoothening agent.  The small granule size also has an impact on oil binding characteristics.  Rice starch is also a good structuring agent in cream fillings and spreads.

Rice amylose is a branched (not linear) polymer – giving you a more soft, creamy gel texture compared to other food starches. Also, rice amylopectin has a unique molecular structure which leads to a reduced tendency for retrogradation – which means that it has excellent freeze thaw and shelf life stability.

One of the most important characteristics of rice starch is it’s neutral flavor – allowing it to be used in many different applications including meats, sauces, soups, bakery products, frozen desserts, and more! Contact us today for how rice starch can benefit your current project.

Changes to the FDA definition of fiber

Have you heard about the FDA’s changes to the definition of fiber? First:  The formal interpretation of the ruling is below:

FDA’s new definition of a dietary fiber is a fiber that has a “physiological effect that is beneficial to human health.” The definition is limited to fibers that are 1) non-digestible carbohydrates (with 3 or more monomeric units) and lignins intrinsic and intact in plants, such as whole grains and natural fruit and vegetable fibers, or 2) added fibers, such as isolated or synthetic non-digestible carbohydrate fibers, including both insoluble and soluble prebiotic fibers, as long as FDA has pre-approved the fiber as a dietary fiber or as long as the ingredient is already the subject of an FDA-approved health claim.

The list of approved fibers is short at the moment (as of July 2016)-  For now, it includes only cellulose, guar gum, pectin, locust bean gum, and hydroxypropyl methylcellulose (HPMC).  Oat beta-glucan and psyllium husk are the subject of health claims so therefore approved as well.

Second: We know that our partner suppliers are to be filing proper documentation to get approved.  Insoluble fiber manufacturers are working together for a more industry wide approach. Click here for more information. 

Food companies have 2 years to comply so there is some time.  These changes are part of the new nutrition facts panel.  FDA is also planning to raise the daily value for dietary fiber from 25 g to 28 g for a 2,000-calorie diet—a level in line with current Institute of Medicine recommendations.  This means the levels of fiber required for “good” and “excellent” source claims are higher as well at 7g and 14g (that’s a lot of fiber!)  Stay tuned for updates regarding fiber, and be sure to stay in touch with us at SPI Group!

Salt is hot in the media right now!

The FDA calls for sharp reduction in salt added to foods

FDA Guidelines target the sodium hiding in our diets 

All because of Draft Guidance published in the CFR for proposed sodium reductions in the “Processed Food” category.  Some of the proposed reductions include the following (values are milligrams per serving):

  • Dry Soup Mix from current average 1892 to 1290
  • Frankfurters, Hot Dogs from current average 1012 to 730
  • Bone-in Batter and Breaded Poultry from current average 599 to 380
  • Flavored Potato Chips from current average 774 to 380
  • White and Wheat Bread from current average 523 and 471 down to 300 for bothBut never fear.  SPI Group is proud to present our sodium reduction toolbox – highlighted here are salt replacers:
  • Saltwell Sea Salt: Water from the ancient Atamcama Sea naturally high in potassium for a 30% sodium reduction and the clean label of “Sea Salt.”  Saltwell allows a 1:1 replacement of salt in label, flavor, and functionality. Saltwell
  • NuTek Salt:  Patented process to form single crystals of potassium chloride with the bitterness masked and functionality of salt.  Clean and simple label: “Potassium Chloride, Maltodextrin” Get more salty taste without the sodium content.saltwell 2
  • Provesta 029: “Autolyzed Yeast, Potassium Chloride” for partial replacement of salt, provides salty flavor while enhancing your existing salt and flavor system
