Food shelf life: how to increase stability

Date: 10/08/2026

A product can be within its expiration date and still disappoint the consumer. This gap between the date indicated on the label and the consumption experience is among the main challenges of food shelf life. When quality deteriorates before the expiration date, the chances of complaints, returns, disposal, and loss of trust increase.

On the other hand, safely extending the shelf life of food requires a comprehensive analysis of raw materials, formulation, processing, packaging, and storage.

In this article, you will find:

What is shelf life and why is it strategic for the food industry?

Shelf life is the period during which a food product remains safe and suitable for consumption under the conditions defined by the manufacturer. Anvisa's Guide No. 16/2018, version 3, defines that this assessment must consider microbiological, physicochemical, nutritional, and sensory aspects.

The goal of the assessment is to identify which attribute is the first to no longer meet acceptance criteria. In some categories, changes in color, viscosity, aroma, or texture limit shelf life before a perceptible health risk arises. In others, pathogenic microorganisms reach critical levels without producing visible signs. The date indicated on the label, therefore, must account for both possibilities and include the safety margin defined by the manufacturer.

The importance of controlling food shelf life is also tied to a context of significant waste throughout the entire production chain. The United Nations Environment Programme estimated that more than 1 billion tons of food were wasted in 2022 across retail, food service, and households, corresponding to 19% of the volume available to consumers.

Between post-harvest and arrival at retail, the Food and Agriculture Organization of the United Nations calculated that 13.3% of food was lost in 2023. In other words, not all loss stems from insufficient shelf life, but more stable products expand the margin for manufacturing, distribution, display, and consumption. In this sense, understanding product shelf life also supports efforts to reduce waste throughout the chain.

What is the difference between shelf life, shelf stable and expiration date?

Concept	What it means	Point of attention
Shelf life	Period during which the food meets safety, quality, and suitability criteria under defined transport and storage conditions.	Must be estimated, tested, validated, and monitored for each product.
Expiration date	Period or date declared on the label by the manufacturer, based on shelf life studies and a safety margin.	This is regulatory information and must be accompanied by special storage conditions, when applicable.
Shelf stable product	Food that can be safely stored at room temperature, sealed and without refrigeration.	Being shelf stable does not mean it lasts indefinitely: the product remains subject to a defined shelf life.

What factors influence food stability?

Anvisa divides these factors into intrinsic, related to the food itself, and extrinsic, related to processing and the environment. The combined effect between them determines which changes limit shelf life and which parameters must be monitored in the study.

Microbiological stability

Bacteria, molds, and yeasts deteriorate the product or compromise its safety. The multiplication of these microorganisms depends, among other factors, on the water they are able to use; this availability is measured by water activity (aw), on a scale of 0 to 1. The closer to 1, the greater the portion available for microbial growth and chemical reactions.

Aw differs from total moisture because salt, sugar, and other components can reduce this portion even in products with similar water content. According to Anvisa's Guide 16, formulations with a final equilibrium pH above 4.6 and/or aw above 0.85 are more susceptible to pathogen multiplication when the other control barriers do not ensure their safety.

Physicochemical stability

Changes in pH, moisture, crystallization, sedimentation, and phase separation alter structure, appearance, and performance. Reactions such as hydrolysis, browning, and nutrient degradation occur at different rates depending on composition, temperature, light, and contact with the environment. Indicators such as viscosity, color, texture, and content of critical components must be selected according to the matrix.

Oxidative stability

Oxygen, light, heat, and pro-oxidant metals favor lipid oxidation. The compounds formed during this reaction can generate volatile aldehydes and ketones associated with rancidity and off-flavors, as well as affect pigments, vitamins, and aromas. Packaging with adequate barrier properties, control of oxygen in the headspace, and technically justified use of antioxidants are among the possible measures, always evaluated together with composition and processing.

Sensory stability

Aroma, flavor, texture, and appearance convey to the consumer changes that began at the microbiological, physical, or chemical level. A food product can remain safe and still be rejected because it lost crunch, developed phase separation, or developed an oxidized note. Sensory analysis throughout the study, including near the end of shelf life, verifies whether the delivered experience remains consistent with the standard approved at launch.

How to increase the shelf life of processed foods?

Shelf life results from complementary barriers. The strategy must start from the factor that first limits the quality or safety of the product and be confirmed through analyses under conditions that represent manufacturing, transport, retail, and consumer use.

● Specify raw materials: define microbiological, physicochemical, and sensory limits and control variation between suppliers and batches.
● Standardize processing: monitor time, temperature, homogenization, and steps following heat treatment to prevent deviations and recontamination.
● Select the appropriate packaging: consider barrier properties against oxygen, moisture, and light, seal integrity, internal atmosphere, and compatibility with the product.
● Define storage conditions: establish realistic temperature and humidity ranges and also assess possible fluctuations during distribution and display.
● Control water activity: adjust formulation and process based on aw measurements, without assuming stability based on moisture content alone.
● Reduce exposure to oxidation: control oxygen, light, temperature, and susceptible raw materials, and evaluate antioxidants suited to the application.
● Balance the formulation: examine interactions between ingredients and revalidate shelf life whenever there is a relevant change in composition, process, or packaging.

How do ingredients influence food shelf life?

Ingredients affect not only nutritional value, but also have the potential to modify pH, water activity, moisture retention, emulsion, viscosity, oxidation potential, and response to heating. In clean label projects within industrial formulation, removing or replacing preservatives, antioxidants, and stabilizers without recovering their functions can reduce shelf life. Each change must be tested in the finished food, since the isolated performance of the ingredient does not predict all matrix interactions.

In sensory stability, Meat Extract from MBRF Ingredients' Food Ingredients line plays a role in building meaty flavor, body, and intensity. Produced by cooking fresh, 100% traceable beef raw material, it is stable at room temperature and is available with 60% or 80% solids. In heat-treated formulations, it helps maintain flavor authenticity and consistency during storage, provided it is validated in the final product.

NatSense Natural Meat Flavors also preserve or intensify meaty notes. These functions do not replace microbiological controls, nor do they alone make a food shelf stable.

Taking application and formulation validation into account, these contributions include:

● Maintenance of sensory stability;
● Preservation of flavor profile;
● Stability during processing;
● Consistent behavior during storage;
● Contribution to shelf stable products.

Application	Possible function of meat extract	Attributes to monitor in shelf life
Soups	Build body, depth, and flavor persistence.	Intensity, homogeneity, color, and aroma after preparation.
Sauces	Build a meaty base and complement the flavor profile.	Flavor, odor, viscosity, color, and phase separation.
Seasonings	Concentrate meaty notes and support standardization between batches.	Aroma retention, moisture, flowability, and uniformity.
Meat products	Reinforce meaty identity, body, and palatability.	Flavor after heating, aroma, texture, color, and oxidation.
Snacks	Compose seasonings, coatings, or fillings with a savory profile.	Flavor persistence, aroma, crunch, and rancidity.
Ready meals	Sustain the sensory base after heating or reprocessing.	Flavor consistency, aroma, texture, and appearance.

What is the importance of the supplier in food stability?

A shelf life study assumes that commercial batches reproduce the tested formulation. Variations in composition, microbial load, or thermal behavior of an ingredient can shift the limiting factor and reduce the projected shelf life. The purchasing decision must take into account technical predictability and cost per performance.

Before qualification, verify:

● Traceability of raw materials and batches;
● Technical support for application, testing, and adjustments

At MBRF Ingredients, the 100% integrated production chain supports control over origin, raw material freshness, and ingredient standardization. The structure also includes:

● Processing with fresh, traceable raw material;
● Research, innovation, and technology, with an innovation center in Jundiaí;
● Quality governance and monitored processes;
● Global presence, with export authorization to markets in the Americas, Europe, Africa, and Asia.

These elements reduce sources of variability and support R&D and quality decision-making. Performance, however, must continue to be confirmed in application, under real process conditions, and throughout the entire proposed period for the product.

Food shelf life: stability begins with ingredient selection

Increasing shelf life requires a balance between formulation, processing, packaging, and storage. Microbiological, physicochemical, oxidative, and sensory stability must be evaluated as a system: intervening in one parameter can alter the others and create a new point of vulnerability.

Meat extract improves the consistency and authenticity of the sensory profile, including in heated products intended for extended storage. Its role must be sized through testing; microbiological safety, oxidation control, and packaging integrity remain dependent on the other barriers.

Selecting ingredients based solely on lowest immediate cost can result in greater variability, reformulations, losses, and consumer rejection. However, the most relevant criterion for ensuring project quality is the verified performance of the formulation throughout the entire shelf life.

Frequently asked questions about food shelf life

What is food shelf life?

It is the period during which the food remains safe, suitable for consumption, and within composition and quality specifications when transported and stored under the conditions defined by the manufacturer. It must take into account microbiological, physicochemical, nutritional, and sensory factors.

What is the difference between shelf life and expiration date?

Shelf life is the useful life estimated and validated through studies. The expiration date is the period or date the manufacturer declares on the label based on this evidence and a safety margin, in addition to any applicable storage conditions.

What influences the microbiological stability of food?

Water activity, pH, initial microbial load, raw materials, hygiene, processing, packaging, temperature, and risk of recontamination. The combined effect of these factors determines which microorganisms can survive or multiply.

How can the shelf life of processed foods be increased?

It is necessary to identify the limiting factor and combine standardized raw materials, controlled processing, compatible packaging, appropriate storage conditions, and a balanced formulation. Every relevant change must be followed by a new shelf life assessment.

What does it mean for a food to be shelf stable?

It is a food that can be safely stored at room temperature, in sealed packaging, without depending on refrigeration. This classification does not eliminate the need for an expiration date or storage instructions after opening.

How does meat extract contribute to food shelf life?

Its contribution is primarily sensory and technological: the ingredient can reinforce meaty flavor, body, intensity, and standardization, supporting profile consistency during processing and storage. The effect must be validated in the formulation and does not replace microbiological safety barriers.

In which products does meat extract contribute to preserving flavor during shelf life?

The ingredient can be evaluated in soups, broths, sauces, seasonings, meat products, snacks, and ready meals. Suitability depends on the matrix, the concentration chosen, the process, the packaging, and the sensory profile defined for each application.
