The extension of food shelf life is not merely through preservatives or extended storage periods. Extending food product shelf-life regulations requires scientifically based formulation, processing, packaging, safety, quality and storage validation. Even though food shelf-life extension regulations may differ according to market, manufacturers must support shelf life through appropriate food stability testing methods, including real-time or accelerated studies, microbiological and physicochemical testing, and compliant labelling.
In the year 2026, food product development, food formulation and shelf-life product development can utilise scientifically based processing, scientifically approved preservatives, protective packaging and storage conditions. The shelf life must meet applicable FDA, EFSA, FSSAI or FSANZ regulations and support accurate “best before” or “use by” dates. [1]

What Is Shelf Life and Why Does It Matter for Food Manufacturers?
Shelf life is the time during which a food product is still safe and possesses its desired characteristics of sensory, physical, chemical, and nutritional characteristics, in addition to meeting its labelling claims under specified storage conditions. It is affected by the food ingredients, food processing, packaging, hygiene, and storage, making it an essential part of food product development and food formulation.
Having a substantiated shelf life results in reduced wastage, increased distribution, and minimised returns, whereas overstated shelf life increases risks of safety, quality, and recall issues. Therefore, manufacturers need to determine probable means of deterioration like microbiological growth, oxidation, migration of moisture, nutrient loss, color or texture changes during Shelf-life product development.
What Are the Key Regulations Governing Food Shelf-Life Extension?
There is no universal global regulation about shelf life. Food shelf-life extension regulations are subject to varying regulations depending on market, food category, process and storage conditions; however, manufacturers need scientific justification for the shelf life of their products.
In the United States, FDA regulations and FSMA focus on food safety, preventive control measures, monitoring, and verification. In Europe, shelf-life verification is also concerned with microbiological criteria of the relevant foods, especially those that can serve as a niche for Listeria monocytogenes growth. [2]
Key insight: The regulatory concern is not only how long the product lasts, but whether manufacturers can demonstrate that it remains safe, meets quality requirements and complies with its label throughout the claimed shelf life.

EFSA Shelf-Life Regulations: Use By vs Best Before Explained
In the EU, use by dates address food safety, while best before dates indicate quality. Manufacturers should select the appropriate date based on the product’s characteristics, treatment, handling and storage conditions; EFSA provides a decision tool to support this assessment.
For those ready-to-eat foods for which shelf-life needs to be validated, consideration of microbiological hazards and any relevant EU microbiological criteria is mandatory. Declared shelf life should consider the results from safety and quality testing. [4]
FSSAI Shelf-Life Requirements for Indian Food Products
FSSAI shelf-life requirements are linked to safety, quality and specified storage conditions. FSSAI’s existing Labelling & Display system requirements mandate that pre-packed foods having required date marking are provided, whereas the regulations continue to get amended, including one in March 2026.
In the case of e-commerce, FSSAI mandates that the delivered food should have a minimum of 30% or 45 days of shelf-life remaining before expiry, whichever is applicable.
Thus, Indian food manufacturers need to determine the declared shelf life by taking into consideration their commercial formulation, processing, packaging and storage conditions rather than relying solely on laboratory or kitchen-scale samples. [5]
FSANZ Guidelines for Shelf Life in Australia and New Zealand
FSANZ Standard 1.2.5 defines ‘use by’ dates for products that need to be consumed within a certain time for safety reasons and ‘best before’ dates, which primarily indicate quality only. The supplier is responsible for determining the correct date, and the necessary storage conditions must be stated where necessary to maintain the product until that date.
Across all these markets, the common principle is clear– shelf-life dates must be determined based on product-specific data, appropriate storage conditions and regulatory requirements rather than assumptions or fixed timelines. [6]
What Are the Approved Methods for Extending Food Product Shelf Life?
No single method suits every product. Shelf-life extension should match the product deterioration, food formulation, and target market regulations. Common methods are:
- Thermal treatment such as pasteurisation, sterilization, and retorting.
- Control of pH and aw.
- Refrigeration, freezing and cold chain management.
- Modified atmosphere or barrier packaging.
- Adequate preservatives and antioxidants.
- Fermentation and non-thermal validated technologies.
- Optimization of formulation for controlled oxidation, moisture migration, and microbial growth.
It is important to ensure Food preservatives regulatory approval and permitted concentrations for the target market. A combination of multiple controls by means of a hurdle approach can offer better shelf-life extension compared to a single method.
How Is Shelf-Life Testing Conducted? Methods & Timelines
The claims related to shelf life must be backed up with food stability testing methods using representative production batches along with the final packaging. Such testing usually includes:
- Microbiological safety and spoilage.
- Physicochemical stability – pH, water activity and oxidation.
- Sensory stability.
- Nutritional or active components stability (if applicable).
- Packaging stability and barrier function.
- Intended storage conditions.
Real-time testing gives information about the stability of the product directly, whereas accelerated testing gives an earlier indication, provided that scientific justification exists. The study duration depends on product, storage conditions and proposed shelf life.
Accelerated Shelf-Life Testing vs Real-Time Stability Studies
Accelerated shelf-life testing (ASLT) involves higher temperatures, higher humidity or increased light exposure for acceleration of degradation processes. In parallel with ASLT, real-time stability studies are conducted on the products under the intended storage conditions during the whole period of the shelf-life claim.
Parameter | ASLT | Real-Time Studies |
Conditions | Elevated temperature, humidity or light | Actual storage conditions |
Purpose | Faster prediction and screening | Shelf-life confirmation |
Duration | Shorter | Full proposed shelf life |
Evidence | Predictive | Direct and more reliable |
ASLT is helpful in formulation and preliminary shelf-life evaluation but cannot be an alternative to real-time information. When microbiological safety is critical, challenge testing can assess pathogen growth. The appropriate method depends on the product, degradation mechanism and regulatory requirements. [1]
