What Meant By a Clean Label?
Clean labels are used in the food industry to describe more consumer-friendly labels and trustworthy natural products. It involves using fewer ingredients that consumers recognize and regard as wholesome, with no artificial flavors, artificial colors, artificial preservatives, or synthetic additives. Clean labeling is not government-regulated and may mean different things to different people. It is a trend driven by consumers’ desire for labels that are easy to read and contain simple information on how ingredients are sourced and products are manufactured.
Clean labels refer to product labels that are transparent, clear, and easy to understand. These labels provide accurate information about the product's ingredients, nutritional content, and any relevant certifications. Here are some examples of clean labels:
Organic Foods: "100% Organic" - Indicates that all the ingredients are certified organic. "USDA Organic" - A label certifying that the product meets the United States Department of Agriculture's organic standards.
Non-GMO Foods: "Non-GMO Project Verified" - A label indicating that the product has been verified by the Non-GMO Project, ensuring it does not contain genetically modified organisms.
All-Natural Products: "All-Natural" - Denotes that the product is free from artificial colors, flavors, and preservatives.
Gluten-Free Foods: "Gluten-Free" - Confirms that the product does not contain gluten, a protein found in wheat, barley, and rye.
Nutritional Information: "Nutrition Facts" - A standardized panel that provides detailed information about the product's nutritional content, including calories, fat, carbohydrates, protein, vitamins, and minerals.
Environmental Certifications: "Fair Trade Certified" - Indicates that the product was produced following fair labor practices and environmental standards. "Rainforest Alliance Certified" - Demonstrates that the product was produced in a manner that supports biodiversity conservation and sustainable livelihoods.
Cruelty-Free and Vegan Products: "Cruelty-Free" - This signifies that the product was not tested on animals during its development. "Vegan" - Confirms that the product contains no animal-derived ingredients.
Simple Ingredient Lists: A clean label may list easily recognizable ingredients without chemical-sounding names, making it clear what the product contains.
"No Artificial Sweeteners" or "No High-Fructose Corn Syrup": Labels that explicitly state the absence of specific ingredients, helping consumers make informed choices about what they want to avoid.
"Free From" Claims: "Dairy-Free," "Soy-Free," "Sugar-Free," etc. - Labels that indicate the absence of certain ingredients for people with specific dietary restrictions or allergies.
Remember that the presence of clean labels does not necessarily make a product healthy or nutritious. It's essential to read the entire label and understand the nutritional information to make informed choices about the foods you consume.

Hydrocolloids Not Universally Considered Clean Label?
Hydrocolloids were not universally considered "clean label" ingredients. Hydrocolloids are a group of substances that can form gels or thicken solutions when they interact with water. They are commonly used in the food industry as stabilizers, emulsifiers, and thickening agents. Examples of hydrocolloids include carrageenan, guar gum, xanthan gum, and pectin.
Whether hydrocolloids are considered a "clean label" depends on the individual's perspective and the specific context. Some consumers and food companies may view certain hydrocolloids as acceptable clean-label ingredients because they are derived from natural sources and are generally recognized as safe by regulatory authorities like the U.S. Food and Drug Administration (FDA) or the European Food Safety Authority (EFSA).
However, others might not consider hydrocolloids as clean labels because they are often processed and extracted from plant materials using various methods. Additionally, some people associate clean labels with minimal processing and may prefer ingredients that are less refined.
As the concept of clean label is not government-regulated and can be subjective, there is no definitive answer on whether hydrocolloids are universally considered clean label or not. It's best to check the definition and criteria of clean labels used by a particular company or certification organization to understand their stance on hydrocolloids and other ingredients.
Hydrocolloids play a crucial role in various food products, and as consumers increasingly demand clean labels and plant-based options, food manufacturers must carefully consider their choice of hydrocolloids for new plant-based products. Nesha Zalesny, an expert in the hydrocolloid market research field and Technical Consultant at IMR International, shared valuable insights on this topic during her presentation titled "Hydrocolloids: Clean Label Tools for Plant-Based Formulating" at the 2020 Clean Label Conference.
Zalesny emphasized the importance of considering key factors, conveniently remembered with the acronym TIPPS, when selecting hydrocolloids among the many choices available. These factors include Texture, other Ingredients in the product, pH, Processing, and Shelf life/storage. She applied the TIPPS approach to various plant-based product categories, including plant-based beverages, cultured products, frozen desserts, and meat substitutes.
Plant-based "dairy" beverages are gaining popularity with various ingredients like almond, soy, cashew, coconut, hemp, oat, and pea. These beverages require a light, creamy, and drinkable texture, containing water, vegetable proteins, and fats with a neutral pH. Often, these products undergo ultra-high-temperature (UHT) processing and may be either refrigerated or shelf-stable.
Hydrocolloids commonly used in plant-based beverages include carrageenan, high-acyl gellan gum, and locust bean gum. Alternative ingredients like tara, gum acacia, oat fiber, and citrus fiber are gaining momentum. Carrageenan, derived from seaweed and widely used globally, provides suspension and emulsion stability but is not suitable for retorted beverages. Gellan gum, especially in high-acyl form, creates a fluid gel with a clean mouthfeel and good protein suspension. Galactomannans, added with gellan gum, enhance stability. Locust bean gum is effective but expensive, while tara gum offers a cost-efficient alternative. Gum acacia can stabilize emulsions in beverages with added fat.
Oat or citrus fiber can be used as alternatives to gellan gum, and oat fiber acts as both a stabilizer and a balancing agent for viscosity. Zalesny also provided troubleshooting tips for using hydrocolloids in plant-based beverages, such as using the correct level of hydrocolloid, ensuring proper hydration and fill temperature, starting with high-quality proteins, and buffering to protect proteins during UHT processing.
The presentation also discussed TIPPS analyses for other plant-based products like yogurts, frozen desserts, and meat substitutes. In the case of plant-based meat substitutes, carrageenan blended with xanthan, locust bean gum, proteins, and starches is used to form a gel for cold cuts with excellent bite and "sliceability." Plant-based burgers, on the other hand, utilize methylcellulose, which remains insoluble in hot water, providing a soft, uncooked texture that firms up during cooking, mimicking ground beef.
How Can a Hydrocolloid Qualify for a Clean-Label?
To qualify as a clean-label ingredient, a hydrocolloid should meet specific criteria that align with consumers' expectations for transparency, simplicity, and health-consciousness. Here are some guidelines to make a hydrocolloid qualify as a clean-label ingredient:
