Efficient Food Ingredient – Citrus Fiber
Making food systems more efficient is an on-going process which includes finding efficient food ingredients that are multi-functional, nutrient dense, cost effective, easy to source, and sustainable. Citri-Fi® citrus fiber is one example of a food ingredient that checks all the boxes. Its water holding and emulsification properties and low usage levels provide cost savings in certain food applications.
If you are a movie buff, you will know that some screenwriters portray futuristic concepts that come true about 95% of the time. For instance, those who are sci-fi enthusiasts can recall movies like Blade Runner 2049 and The Island which share ideologies about the food system and nutrition. In Blade Runner, Earth turned into a state of environmental disaster. Humanity procured its only food source from nematodes (worms) which contained high levels of protein. Though gruesome to watch, this efficient food sourcing was not too different from today’s insect farming. This efficient food ingredient, insects, are a staple in many countries around the world.
And in the movie The Island, Ewan McGregor finds himself born in a colony of people held in a compound. A computer print-out dictated his daily food choices every morning to maintain his perfect health. Little did he know, his community thrived in pristine health because they were clones of wealthy people. McGregor and the other’s organs and body parts were surrogates in case their owners needed a transplant. The fascinating part was the suggested customized nutrition in the movie mirrored present day's nutrition goals.
Both examples point to human being’s pursuit of efficiency whether it is from sustainable protein sources to customized nutrition. Because of this progressive trend, our food system continues to strive for more efficient food ingredients that are sustainable and healthy.
Defining Efficient Food Ingredients
What does efficient mean when referring to food ingredients? According to Merriam-Webster (2025), efficient means “capable of producing desired results with little or no waste (as of time or materials)”. If we apply that meaning to food ingredients, it implies producing little or no waste in the production, sourcing, handling, and usage of a food ingredient. If we take it a step further and either use internet searches or AI generators to pump information, we get a more encompassing definition for an efficient food ingredient.
An efficient food ingredient includes various factors such as multi-functionality or multi-purpose, nutrient density, cost effectiveness, easy sourcing, long shelf-life and sustainability. All of these aspects apply to all stages of creating a food ingredient including its afterlife in a finished food product.
Two for the Price of One: Multifunctional Ingredients
Many food products use multiple hydrocolloids for different functionalities. It is no wonder that some of the food ingredient declarations resemble a lengthy novel. For example, a food product may contain multiple texturizing and stabilizing ingredients. Certain hydrocolloids like starches and plant-based fibers are used to hold water while emulsifiers are used to bind oil and water. And then throw in a suspension agent, typically a food gum, to prevent settling.
Citri-Fi citrus fiber which is produced from byproduct of the citrus juicing industry uses a process that is free from chemical modifications. This process opens up the fiber to provide multiple contact points for water and oil binding. Citri-Fi can hold up to 9-10 times its weight in water and three times its weight in oil. As a result, this dual functionality – water holding and emulsification properties – can replace several ingredients in a food formulation to shrink food ingredient lists.
In addition, Citri-Fi can provide this dual functionality at a fraction of the usage level (<1%) compared to other ingredients. For example, some ingredients like modified food starches work best at 3-4% usage. And depending on the food application, formulators may need to overuse the starch to get the full functionality due to limited food processing tolerance (e.g. low pH, high shear, high heat, etc.). Unlike those ingredients, Citri-Fi citrus fiber’s high stability in most food processing conditions fosters a low usage level making it an efficient food ingredient.
Nutrient Dense Ingredients
When formulating foods, many ingredients’ sole purpose is to provide stability and/or improve texture. Nutrition falls lower on the list of success criteria. However, an efficient food ingredient will provide both functionality and nutrition. Some food gums qualify as dietary fiber. And plant-derived fibers register as dietary fibers. However, most starches modified to hold water or emulsify do not contribute dietary fiber. Emulsifiers are also created for one specific functionality – emulsification.
Citri-Fi citrus fiber qualifies as a dietary fiber under the FDA. It contains about 80% total dietary fiber where half is insoluble and half is soluble fiber. Because of this, Citri-Fi contributes fiber to the finished food product’s nutritional panel. However, since Citri-Fi is used at low usage levels, it typically requires other dietary fibers to be used to make fiber claims.
Labeling options include citrus fiber, dried citrus pulp or citrus flour which resonate well in the clean label markets. Citri-Fi’s labeling carries an innate health halo that consumers understand. On the other hand, some food gums sound suspect while modified food starches implies chemical use.
Cost Savings Using Efficient Food Ingredients
Another defining moment for an efficient food ingredient is the cost savings they provide. Although there is a tendency to judge a food ingredient’s value based on the price per pound or kilogram, efficient food ingredients offer a cost-in-use savings. But what does that mean?
When product developers use ingredients for textural or stability, those ingredients may also provide efficiencies in food systems such as shorter processing times or lower temperatures. For instance, Citri-Fi is functional in all temperatures. Alternatively, certain food gums and starches require specific temperatures or conditions to activate. Efficient food ingredients like Citri-Fi can be used to reduce the reliance of more expensive ingredients in a formulation. For example, Citri-Fi can reduce egg and/or oil content, animal meat in processed meats and pricey vegetable or fruit pulp while still maintaining a high-quality product.
Food Ingredient Sourcing Availability
Another feature of an efficient food ingredient is the availability. Citri-Fi citrus fiber is sourced from multiple citrus juice producers and manufactured in the U.S.A. Many other food ingredients originate from unstable geopolitical regions or from areas with fickle climates. Due to this, limited ingredient availability may not only pose a risk but also the escalating price, due to supply and demand, may burden the buyer.
Sustainable & Upcycled – Citrus Fiber Fame
In addition to all the above, efficient food ingredients typically have a sustainable story to tell. As previously mentioned, Citri-Fi is derived from byproduct of the citrus juicing process. The peel which would have been discarded to a lower-valued use (like animal feed) is reclaimed by Fiberstar and converted into a natural plant-derived fiber used to improve the texture, stability and nutrition of a variety of foods and beverages. Organic citrus fiber, Citri-Fi 400, is now available.
Citri-Fi’s efficiency comes in the form of multi-functionality, clean labeling, nutrient density, cost savings, availability and sustainability. Food formulations benefit in using this citrus fiber not only to improve food products labeling and quality, but also, to tell a story about how one little ingredient can check numerous boxes in the food world.
Hopefully, sci-fi screenwriters will continue to muse what our food systems will look like in the distant future. If our tendencies are to continue down the path of efficiency, upcycled food ingredients like citrus fiber definitely have a role. Move over Leonard Nimoy (Spock), we have a new actor (citrus fiber) that Scotty can beam up.
