Best Used By Dates in Nutrition Labeling

September 14, 2023

The determination of products Best Used By date is so much more than a tiny stamp on your product. Best Used By dates is an intricate intersection of science and consumer safety that helps ensure consumers can enjoy a product at its optimal quality. Shelf-life testing is an integral procedure in the food industry and provides an empirical foundation for establishing the Best Used By date on food products. These seemingly simple dates printed on packaging are a cornerstone of ensuring product quality and are derived from complex science and meticulous testing.  Retailers will require this information if you want your product on their shelf consumed by the public.

Decoding Date Labels

First, you must understand the difference between various date label types and the intent behind each to ensure accurate communication to consumers. Manufacturers must be clear on the goals of testing and date labeling. For example, do they want to know when a product begins to lose its optimal flavor or when it becomes unsafe?

  • “Best Used By” or “Best Before”: These lean towards quality rather than safety. After this date, the product might undergo perceptual changes but typically remains safe.
  • “Sell By”: An indicator primarily for retail partners, guiding inventory rotations. However, many products remain safe and quality-consistent beyond this date.
  • “Use By”: The final recommended date for optimal product quality. While often not a safety warning, exceptions exist (e.g., specific baby foods).

The Theoretical Significance of the Best Used by Date

The implications of the Best Used By date extend beyond mere consumption recommendations.

  1. Consumer Trust Establishment: This date acts as an implicit contract between manufacturers and consumers, affirming the product’s optimum quality and safety up to a certain point.
  1. Inventory Management and Retail Considerations: Retailers utilize this date as a primary criterion for inventory rotation, ensuring that products are sold while they are within their peak quality window.
  2. Regulatory Compliance and Ethical Imperatives: Adherence to industry standards and guidelines is both a legal and ethical obligation, underscoring the necessity for accuracy in date determination.

The Intricacies of Determining the Best Used By Date

Once the shelf-life testing has identified a point where the product begins to deviate from desired quality attributes (without posing safety risks), manufacturers can set the Best Used By date. This date is not about safety but rather about quality. It tells consumers when the product is likely to remain at its best. Several factors are taken into account when determining this date:

  • Evaluation of Product Characteristics: Initial assessment requires a clear understanding of the product’s defining attributes—whether textural, olfactory, or gustatory.
  • Simulation of Typical Storage Scenarios: An empirical analysis of product behavior under diverse storage conditions is paramount, from temperature-controlled environments to varied humidity levels.
  • Systematic Monitoring and Analysis: Periodic sampling offers insights into the product’s chronological evolution, allowing for the identification of potential degradation markers.
  • Microbiological Assessment: This phase ensures that the product remains devoid of pathogenic microorganisms or spoilage indicators, especially vital for perishables.
  • Sensory Evaluation: Employing experts to conduct detailed sensory analyses can offer invaluable insights into any nuanced alterations in the product’s profile.
  • Chemico-physical Examination: Delving into potential chemical or physical changes aids in identifying shifts that might compromise product integrity.

Challenges in Best Used By Date Determination and Potential Solutions

The process, while rigorous, encounters its set of challenges:

  • The Balance in Accelerated Testing: While rapid shelf-life testing offers a temporal advantage, it’s imperative to juxtapose accelerated outcomes with real-time data.
  • Synthesizing Diverse Expert Feedback: Disparate expert opinions necessitate a careful distillation process to arrive at a consensus, ensuring the derived feedback is balanced and representative.
  • Incorporating Consumer Variabilities: Factoring in potential consumer-induced variables—such as unintended storage conditions—is essential for a holistic assessment.
  • Ongoing Verification: Because factors such as ingredient sourcing, manufacturing processes, or storage conditions can change, it’s crucial for manufacturers to periodically revisit and, if necessary, revise the “Best Used By” date.

Partnering with RL Food Testing

RL Food Testing is a 5-star reviewed and trusted partner that specializes in guiding customers through the maze of testing and labeling services.
