BLOG: Top 5 Things you Need to Know about Clean Label Yogurt

1. Yogurt manufacturers are cleaning up their label.

Yogurt, started its life with simple ingredients during a time where refrigeration and shelf stability was limited. In the past, yogurt textures depended on the natural cultures in the environment and milk type used. Today, there is a spectrum of yogurt textures littered on the retail shelves. This is partly due to the use of varying stabilizers, fruit fillings, processing techniques and dairy bases in addition to the cultures.

Right when yogurt manufacturers had dialed in their formulation and put their processes on auto-pilot, the market shifted. This shift was towards cleaner labels. It is a marvel that consumers are actually glancing away from their smartphones to read food labeling. And using their own biases, they decide what is considered natural or not in a split second. As a result, some of these stabilizers are not as natural sounding to the average consumer after all.

Yogurt may be one of those foods carrying a health halo. However, labeling is becoming king in this market. So yogurt manufacturers took note of the label reading and began to re-formulate their yogurts to serve their target consumer base.

2. Clean label is a global trend hitting all foods including yogurt.

Creating natural sounding labels is not an isolated incident. This clean label movement is prevalent in Europe, North America and Australia/New Zealand. There is also a smattering of demand in Asia, South America and Africa.

Most would assume only highly processed food manufacturers are weeping heavily over the market shift to natural labels. However, food manufacturers are realizing that it affects all foods and beverages in this market. Those manufacturers proactively benchmarking their products’ labels are the front-runners in this competitive scene.

3.  There are a variety of stabilizers used in yogurts.

Varying stabilizer systems are used in yogurts. For instance, some of the common stabilizers include the following: pectin, modified starch, dairy proteins, cellulose gel, locust bean gum, gelatin, alginates and carrageenan. Each stabilizer either alone or in combination provides improved body and texture, increased firmness, minimal separation or syneresis and suspension of particulates like fruit.

4.  There are clean label stabilizers available in the market.

 Since there is no regulated definition for natural or clean label, formulators scramble to understand which ingredients are safe havens. No matter which ingredient comes into question, there is some sort of bias for or against it. Yogurt manufacturers need to understand their target consumer’s label sensitivities. For instance, one stabilizer can be considered natural to one consumer base but not to another depending on the brand.

This is not a testimony saying one stabilizer trumps the other. This blurb is to point out that manufacturers should be aware there is no one size fits all when it comes to selecting clean label stabilizers for yogurts. So suppliers are burning the midnight oil in order to launch new options into the marketplace.

5.  Citri-Fi® citrus fiber in clean label yogurt is an ideal fit.

For those still scratching their heads over this whole ordeal, there is one natural ingredient they should consider – citrus fiber. Although this is not one of the usual suspects when formulating yogurt, there is one feature that rules – clean label. Within the U.S., the USDA approved the following labeling for dairy products – dried citrus pulp or citrus flour.

Ok,  so it is clean label. So why choose citrus fiber in yogurt?

There are several citrus fibers in the marketplace, however, they are not all the same. Citrus fiber’s composition and structure tell the real story behind its stellar functionality. For instance, Citri-Fi natural citrus fiber is created from byproduct of the juicing processing. The patented physical process opens up the fiber to provide high water holding and emulsification properties. Yes! This can provide multiple functionalities in yogurts.

Citrus Fiber Incorporation and Usage

Citri-Fi, a clean label stabilizer, holds onto the water and fat in the system and stabilizes it over time. As a result, this natural ingredient improves the thickness and texture. Less is more when using this natural citrus fiber in yogurt. The recommended usage level is between 0.1% to 0.6%. However, higher usage levels create thicker and creamier yogurts. Citri-Fi comes in a few particle sizes which also helps target specific yogurt textures.

The incorporation process into clean label yogurt is simple. First the cream, milk or any other dairy base are mixed together. This clean label stabilizer powder is slowly added into a vortex while mixing at high speed. The batch is kept lightly agitated to prevent settling until pumped into a pasteurization unit. Once through, the mixture cools down to 43°C and is filled into clean containers. The culture is added and then the containers are incubated at 43°F until a pH of 4.4 to 4.5 is reached. That is about eight hours.

Citri-Fi clean label stabilizer is non-GMO, allergen-free and gluten-free. It has no E-number which is key in certain markets. This natural ingredient is plant-based and vegan. So there is opportunity to use this natural ingredient in dairy-free systems to improve stability, thickness and texture.

BLOG: Top Frequently Asked Questions (FAQ)

Citri-Fi Frequently Asked Questions

When the Fiberstar team works with developers, several frequently asked questions arise about Citri-Fi citrus fiber. Since this fiber is a highly functional fibers and not typically used for fiber fortification, manufacturers inquire more about its benefits.

1.  What is Citri-Fi® and what is it’s base material?

Citri-Fi natural citrus fiber is made from byproduct of the citrus juicing process. This natural fiber is made from the following: juice cells, peels, rag or segment membranes and cores from mandarin oranges (excluding bitter oranges) lemons, limes grapefruits and tangerines. Citri-Fi has about 74% dietary fiber where 38% is insoluble fiber and 36% is soluble fiber. This natural fiber contains a significant amount of pectin (~40%). High Brix and low pH conditions activate the pectin in the fiber to produce gelling properties which are beneficial for fruit prep food applications.

The patented, physical process opens up the fiber to provide high water holding and emulsification properties which benefit foods like meats, bakery, dressings, sauces, beverages, dairy, pet food and treats, frozen foods, and plant-based foods.

 

2.  How is Citri-Fi labeled?

Citri-Fi can be labeled as citrus fiber, dried citrus pulp or citrus flour. In USDA regulated foods, this natural ingredient can be labeled as citrus flour or dried citrus pulp. Regulations about labeling can vary by country.

 

3.  Does Citri-Fi have any taste?

Citri-Fi citrus fiber has a neutral taste. During the citrus juicing process, the fiber goes down one channel while the flavor containing components go down a separate channel. The citrus juice processing companies keep the flavor components which are turned into value-added products further down their byproduct streams which benefits them. Meanwhile, we ensure the fiber that we procure has a bland taste by extensively washing the raw material with water. This removes both oils and sugars down to a very low level. In fact, we do sensory on each lot of Citri-Fi that’s made to ensure the taste profile fits within customers’ specifications and expectations.

 

4.  Does Citri-Fi provide heat stability in foods?

One of the unique properties of Citri-Fi is heating stability and its ability to bind both water and oil when heated.  Thus, Citri-Fi provides heat stability in many types of foods such as bakery, meats, dressings and sauces. Citri-Fi’s high surface area combined with its natural composition, which contains native pectin and proteins, locks in water and oil which remain stable during heated conditions.

When used in bakery applications, the Citri-Fi holds onto the water pre and post bake. As a result, the baked good remains soft which improves quality over time. In meat products, Citri-Fi holds onto the water during the cooking process which improves the cooked yield and gives the poultry products a succulent and juicy texture. And in dressing and sauces, Citri-Fi holds onto water and oil if present so that there is no separation during and after cooking.

 

5.  How to incorporate Citri-Fi in foods?

Citri-Fi natural citrus fiber can be incorporated into foods via adding to dry ingredients or fat and/or oil. In liquid applications, like other hydrocolloids, the citrus fiber needs to be dispersed either by being mixed in with other dry ingredients or added alone with some agitation to prevent fish eyes from forming.

Citri-Fi does not need to be pre-hydrated nor heat activated. This natural citrus fiber begins to swell immediately in aqueous conditions. When forming emulsions, Citri-Fi is first mixed dry with the oil and/or fat and then added to the liquids. After some agitation, the emulsion will form which then can be added to the food product.

If there is no shear available, there are options such as adding Citri-Fi to oil first then adding water. Or another method is to slowly add Citri-Fi into water to avoid  large amounts of dry material contacting water all at once, which can create clumps. Additionally, if a larger particle size of version of Citri-Fi is used, it will be less prone to clumping when first added to solution. However, even if clumps do form in water with the smaller particle sizes (e.g. Citri-Fi 100M40), they do readily break up on their own without shear after a period of 15-20 minutes.

 

6.  Does Citri-Fi provide freeze/thaw stability?

Citri-Fi natural citrus fiber provides freeze/thaw stability which benefits several foods including ice cream, sauces, meat alternatives, and frozen meals. This natural fiber’s high surface area locks in the water and oil during freeze/thaw minimizing water migration. This gives frozen foods excellent stability over time improving the quality.

 

7.  Does Citri-Fi provide emulsification?

The Mechanism

Citri-Fi holds up to seven times its weight in oil and/or fat. This natural fiber's physical and chemical composition create the emulsification properties. For instance, the native pectin and protein in Citri-Fi provide hydrophobic interactions with fats and oils to help stabilize emulsions. Additionally, on the physical side, Citri-Fi has a very amorphous cell wall structure where oil droplets can get  physically trapped and be prevented from coalescing with other droplets. This also helps to form a more stable emulsion. In certain products, depending on the concentrations and other ingredients used,  there can also be a viscosity impact which also creates a physical barrier for oil droplet coalescence. Without oil droplet coalescence, the emulsions essentially remain stable for longer periods of time. Thus, multiple mechanisms allow Citri-Fi to function as an emulsifier.

One key competitive advantage is that low shear or low energy is needed to activate the Citri-Fi, which is contrary to most emulsifiers on the marketplace. A clean natural texture that has minimal taste with long term stability are other benefits.

Stability

We have an study on stability of Citri-Fi as an emulsifier. This study includes challenging conditions such as freeze/thaw, elevated temperatures, and various types of fats and oils. In short, stability of Citri-Fi as an emulsifier remains stable for over 6 months!

In terms of replacing other emulsifiers, Citri-Fi works best if it is the only emulsifier used to help ensure there is no competition and it can fully hydrate to take advantage of Citri-Fi’s high surface area.

Any application will work for Citri-Fi to provide emulsification as long as there is enough water to allow the product to hydrate. If the Citri-Fi does not hydrate, it’s functional properties for oil binding are considerably lower versus if the Citri-Fi is hydrated to take advantage of its high surface area once it comes in contact with water.

Other Applications

This natural fiber also turns difficult-to-use liquids into flow-able powders by dry plating. Citri-Fi has an oil load between 25% and 30% depending on the liquid oil and up to 50% with solid fats. The Citri-Fi not only delivers oil but also provides functional benefits in the final food products. For instance, plated Citri-Fi improves mouthfeel, oil stabilization and clouding in beverage products. Meats and sauces also benefit from plated oils.

 

8.  Is Citri-Fi pH stable?

Citri-Fi is pH stable as low as 3.0. This natural fiber does not break down or lose its efficacy as a dietary fiber. This natural fiber is also pH stable under high heat conditions.

 

9.  What is WHC and how long does Citri-Fi hold onto water?

Water holding capacity (WHC) is the ability of food to hold its own or added water during the application of force, pressure, centrifugation, or heating. (Trends in Food Science & Technology, 2016) Citri-Fi can hold up to 9 to 10 times its weight in water.

Like the emulsification shelf life stability, one of Citri-Fi’s key attributes is long term stability. This is in part because of the product’s natural composition without chemical modification. Thus, products can be stable with Citri-Fi for multiple years without breakdown as long as there is no microbial growth impacting the quality of the overall food or beverage.

Fiberstar, Inc. Showcases Citri-Fi® Natural Citrus Fiber to Replace Phosphates in Meats

RIVER FALLS, Wisconsin, July 2, 2019 /PRNewswire/ -- Exceeding total intake of phosphates from foods is a growing concern among many in Europe. As a result, this red flag triggered groups to re-evaluate safe levels of consumption. Many foods use phosphates since they improve food safety. However, today, there are phosphate replacement solutions available in the marketplace. One solution includes Citri-Fi natural citrus fiber. This clean label fiber is produced with no chemical modifications.

Citri-Fi provides high water holding capacity and emulsification properties. As a result, there are several ways to use this ingredient to replace phosphates in meats. First, this natural citrus fiber in conjunction with ingredients such as starches, gums or carrageenan replace phosphates without compromising quality. Citri-Fi holds onto the water.  The other water loving ingredient creates the viscosity and gel matrix to maintain high yields. Citri-Fi usage level ranges between 0.3%-0.5%.

Moreover, another popular method is to use this clean label fiber in combination with sodium carbonate. Sodium carbonate relaxes the animal muscle to allow more water to bind. Meanwhile, Citri-Fi holds onto the water to maintain high yields and reduce purge in meats. Citri-Fi usage ranges between 0.2% to 0.4%. Studies show that injected poultry using Citri-Fi and sodium carbonate together improved yields by more than 4% versus poultry injected with no phosphates. Coincidentally, many meat processors already use sodium carbonate as a processing aid or for other purposes.

Citri-Fi is non-GMO, allergen-free and has no E-number. This natural citrus fiber is a Product of the USA. Citri-Fi can be labeled as citrus fiber, dried citrus pulp or citrus flour. Please visit Fiberstar at Booth 6K80 at Food Ingredients Europe in December to learn more.
