Ultra-Processed Food Labeling: What Manufacturers Need to Know About Reformulation, Testing, and Compliance

Ultra-Processed Food Labeling:

What Manufacturers Need to Know About Reformulation, Testing, and Compliance

As federal discussions around ultra-processed foods continue, manufacturers face important questions about ingredient selection, nutritional quality, product reformulation, and the potential impact of new labeling standards.


Ultra-processed foods (UPFs) have become a major focus of nutrition research, consumer interest, and food policy discussions in the United States. As regulators work toward a clearer definition of ultra-processed foods, manufacturers are beginning to consider how future labeling requirements could affect their products, ingredient sourcing, and production costs.


The challenge extends beyond identifying which products may qualify as ultra-processed. Changes to ingredients and manufacturing processes can affect nutritional composition, food safety, shelf life, and product quality. For manufacturers considering reformulation, understanding these relationships is essential.


Although the U.S. Food and Drug Administration (FDA) has taken steps toward developing a federal definition of ultra-processed foods, there is currently no comprehensive federal requirement to label packaged foods as ultra-processed. However, growing attention to food processing and ingredient transparency makes this an important issue for manufacturers to monitor.

What Are Ultra-Processed Foods?

Ultra-processed foods are generally described as industrially formulated products containing ingredients or additives that are not commonly used in home cooking. These ingredients may serve specific purposes, including improving texture, flavor, appearance, consistency, or shelf life.


One of the most widely used approaches to classifying ultra-processed foods is the NOVA classification system, which divides foods into four categories based on the nature, extent, and purpose of processing. Under NOVA, ultra-processed foods fall into Group 4 and may include products such as packaged snack foods, flavored beverages, certain breakfast cereals, ready-to-eat meals, and some processed meat products.


However, the classification is not always straightforward. A food can undergo substantial processing without necessarily being classified as ultra-processed. Likewise, some products containing beneficial nutrients may fall within the ultra-processed category because of particular ingredients. For example, a whole-grain bread containing emulsifiers may be classified as ultra-processed, while a simpler product with a less favorable nutritional profile may not meet the same criteria. This distinction raises an important question for food manufacturers: Should a product's processing classification, nutritional composition, or both determine how it is labeled?

Why Is Defining Ultra-Processed Foods So Complicated?

Unlike established food labeling requirements that rely on measurable nutrient values, ultra-processed food classification considers ingredient characteristics and processing methods. A product's classification may depend on whether it contains certain emulsifiers, flavoring agents, sweeteners, stabilizers, or other ingredients associated with industrial food production.


This creates several challenges.



First, ingredients can serve multiple purposes. An emulsifier may improve texture and product consistency, while a preservative may help control microbial growth or prevent spoilage. Removing these ingredients can affect how the product performs throughout its intended shelf life.


Second, processing classification does not necessarily reflect nutritional quality. Some products considered ultra-processed provide protein, fiber, vitamins, or minerals. Conversely, products made with relatively simple ingredients may contain substantial amounts of sodium, saturated fat, or added sugars.


Finally, different classification systems and proposed regulatory approaches may use different criteria.

In 2026, federal agencies advanced work on a proposed definition of ultra-processed foods to support more consistent research and future policy development. However, establishing a definition is separate from implementing mandatory labeling requirements. This uncertainty makes it important to distinguish between established regulations, proposed policies, and voluntary labeling or certification programs.

How Could Ultra-Processed Food Labeling Affect Manufacturers?

If future regulations require manufacturers to identify ultra-processed foods on product labels, the implications could extend well beyond packaging changes. Manufacturers may need to review ingredient specifications, evaluate product classifications, update labeling documentation, and determine whether reformulation is appropriate.


The potential impact will depend on how ultra-processed foods are defined, which products are covered, and whether exemptions are available for foods that meet specific nutritional criteria. For companies with large product portfolios, even relatively small formulation changes could involve substantial development and validation work.


The costs of reformulation may include sourcing alternative ingredients, adjusting production processes, conducting nutritional analyses, performing shelf-life studies, and updating packaging. However, reformulation is not necessarily required simply because a product is classified as ultra-processed. Any future obligation would depend on the specific requirements of an adopted law or regulation.

What Happens When Manufacturers Remove or Replace Ingredients?

Replacing an ingredient may appear to be a relatively simple way to reduce a product's processing classification. In practice, many ingredients perform several functions within a food formulation. For example, removing an emulsifier from a baked product may change the distribution of fats and moisture, affecting texture and product stability. Replacing a synthetic preservative with an alternative ingredient may influence microbial growth or shorten shelf life if the new formulation does not provide equivalent protection.


Similarly, changing sweeteners, starches, proteins, or stabilizers can affect water activity, viscosity, flavor, appearance, and nutritional composition. These changes can also interact with packaging materials and storage conditions.



As a result, manufacturers should evaluate reformulated products as new or modified formulations rather than assuming that existing product testing remains applicable.

Why Is Shelf-Life Testing Important During Reformulation?

Shelf-life testing is particularly important when manufacturers modify ingredients that influence microbial stability, moisture retention, oxidation, or texture. A reformulated product may initially appear comparable to the original but behave differently after several weeks or months of storage.


For example, replacing an ingredient that helps retain moisture may cause a product to dry out more quickly. Changes to fats or oils may increase susceptibility to oxidation, potentially affecting flavor and aroma. Removing certain preservatives may alter the conditions that previously helped control spoilage organisms.


Depending on the product, shelf-life evaluations may include:

  • Water activity testing: Evaluates the availability of water for microbial growth and certain chemical reactions.
  • Microbiological testing: Helps assess microbial quality and, when appropriately designed, relevant food safety concerns.
  • Oxidative stability testing: Examines changes in fats and oils that may contribute to rancidity.
  • Moisture analysis: Measures moisture content and helps identify changes that could affect texture or stability.
  • Real-time and accelerated shelf-life studies: Evaluate quality changes during storage, with accelerated methods used when scientifically appropriate for the product.


Testing requirements should be based on the formulation, processing method, packaging, intended storage conditions, and potential food safety hazards. Accelerated shelf-life testing can help identify certain quality changes more quickly, but it does not automatically replace real-time studies or validation of microbial safety.

How Does Reformulation Affect Nutrition Facts Labels?

Changes intended to reduce ultra-processed ingredients can also affect the nutritional composition of a finished product. For example, replacing a modified starch, protein ingredient, sweetener, or fat source may change the product's carbohydrate, protein, fat, fiber, or calorie content. Even when the reformulated product looks and tastes similar, its nutritional profile may differ from the original.


Consideration should be paid to whether the changes affect declared nutrient values, serving-size calculations, ingredient statements, allergen declarations, or nutrient content claims. Nutrition analysis can help verify the composition of reformulated products and support accurate Nutrition Facts labeling.


Importantly, a product marketed as minimally processed or made with fewer ingredients is not automatically nutritionally superior. Nutrient content and processing classification provide different types of information, and both may be relevant when evaluating the finished food.

Could Ultra-Processed Food Labeling Increase Manufacturing Costs?

One of the most significant concerns surrounding potential ultra-processed food labeling requirements is the cost of implementation. Manufacturers may face additional expenses associated with ingredient substitutions, supplier qualification, production adjustments, laboratory testing, packaging revisions, and regulatory review. These expenses can be particularly challenging for smaller food manufacturers that have limited research and development resources or rely on specialized ingredient suppliers.


Ingredient availability is another consideration. Replacing a commonly used ingredient with an alternative may increase raw material costs or introduce new supply chain requirements. The cost of maintaining product quality should also be considered. An alternative ingredient may satisfy a particular classification standard but perform differently during processing or storage. For this reason, reformulation decisions should consider the entire product, including nutritional quality, food safety, manufacturing feasibility, shelf life, and cost.

What Should Food Manufacturers Do to Prepare for Potential Labeling Changes?

Although comprehensive federal ultra-processed food labeling requirements have not been established, manufacturers can begin evaluating their products and documentation without committing to unnecessary reformulation.


A practical starting point is reviewing existing ingredient lists and understanding the technological purpose of each ingredient. This includes identifying ingredients used for preservation, texture, flavor, stability, and nutritional enhancement.


Current nutrition data, supplier specifications, and available shelf-life studies should be reviewed to establish a reliable baseline for future product comparisons. When considering ingredient substitutions, laboratory testing can help determine whether a proposed formulation maintains the desired nutritional composition, safety, and quality characteristics.


When developing new products, these considerations can be incorporated earlier in the formulation process. Evaluating ingredient functionality and testing requirements during product development may reduce the need for additional changes later. Most importantly, manufacturers should continue monitoring FDA guidance and federal and state labeling developments while distinguishing proposed requirements from enforceable regulations.

What Is the Future of Ultra-Processed Food Labeling?

The discussion surrounding ultra-processed foods reflects a broader interest in understanding how ingredients, processing methods, and nutritional composition affect dietary health. However, translating these concerns into consistent labeling requirements presents scientific and practical challenges.


A standardized definition could help researchers compare findings, improve consumer understanding, and provide manufacturers with clearer expectations. At the same time, any labeling framework will need to address the differences between processing classification and nutritional quality. The most effective approach is to rely on measurable product characteristics and scientifically supported formulation decisions. Ingredient transparency, accurate nutrition labeling, food safety testing, and shelf-life validation will remain important regardless of how future ultra-processed food regulations develop.


As manufacturers evaluate potential reformulation strategies, understanding how individual ingredients contribute to product performance will help them make informed decisions without compromising safety, quality, or nutritional value.
