A product’s shelf life is vital within the meals manufacturing sector. Producers can predict how lengthy a product will retain its high quality after manufacture by means of shelf-life testing. The shelf-life check additionally permits corporations to find out an correct expiration date for a product when it reaches shoppers.

When testing a product’s shelf life, producers require a technique that produces an correct end result within the shortest time attainable. One in every of such strategies is accelerated shelf life testing, which shortens the real-time simulation course of.

Learn extra about accelerated shelf-life testing and its vital advantages.

However First: What Is Shelf life?

It’s the interval after manufacturing {that a} product retains its high quality and stays protected to be used.

When figuring out shelf life, producers think about a number of elements that may decide how lengthy the product will final.

Shelf life is determined by the next:

Uncooked Supplies

Each product consists of uncooked supplies that kind the majority of its composition. If a product accommodates uncooked supplies, the shelf life is determined by the supplies used.

As an illustration, altering the uncooked supplies of a product by means of processing or storage would require a assessment of the ultimate product’s shelf life. If unaltered, the product’s shelf-life could also be shorter or longer than anticipated.


Totally different merchandise require totally different packaging circumstances. Consequently, shelf life varies in keeping with the packaging materials used for the product.

Vacuum packaging, for example, removes air from the packaging materials earlier than sealing it. When producers take away air from the packaging materials, micro organism that develop within the presence of oxygen don’t have any appropriate atmosphere for survival. Consequently, the product can last more.


The storage temperature determines how lengthy a product will retain its high quality after manufacture. Subsequently, making use of a constant temperature regime throughout storage and manufacturing is crucial.


Customers will usually use meals merchandise in high-risk and low-risk environments. In a high-risk atmosphere, the goal is to forestall meals contamination from present microorganisms. However, a low-risk atmosphere focuses on decreasing the expansion of micro organism.

Whether or not excessive danger or danger, the extent of hygiene determines how lengthy a product will final after manufacture.

Utilization After Opening

As soon as opened, varied merchandise have totally different shelf lives. As an illustration, a pack of flour will last more after opening than a packet of contemporary fruit juice. Thus, when manufacturing merchandise, producers think about the probability or unlikelihood of utilizing a product instantly after opening the packaging materials.

Accelerated Shelf-life Testing (ASLT)

ASLT is an oblique strategy of figuring out a product’s shelf life, the place producers retailer merchandise beneath extremely irritating circumstances. Via a scientific method, producers can facilitate physiochemical adjustments that promote degradation.

Below ASTL, temperature and humidity are important to facilitate degradation circumstances. By setting storage temperatures and humidity inside predetermined instances, producers can predict the shelf life and assign an expiry date.

As an illustration, a product that retains its high quality at a temperature of 40 levels Celsius and 75% relative humidity for six months can have a 24-month shelf life.

Accelerated shelf-life testing is important when producers need to make fast selections in a short while. The tactic additionally is useful if product producers are beneath stress to launch a brand new product inside brief discover.

The success of a product’s shelf life testing is determined by floor texture, moisture content material, and pH ranges. Consequently, not all merchandise will qualify for the accelerated shelf-life testing process.

Widespread merchandise launched beneath accelerated testing embrace:

  • Confectionary merchandise equivalent to bread and biscuits.
  • Dry powdered merchandise.
  • Dry cereals.

Advantages of Accelerated Shelf-life Testing

Because the title suggests, probably the most unbelievable perk that ASLT presents is the shortened time of shelf-life testing. Not like typical shelf life testing, the place producers use real-time simulation to degrade a product, ASLT facilitates fast degradation, decreasing the shelf life testing time by half the usual time required.

As well as, ASLT presents the next advantages:

Accelerated Shelf-life Prediction

Not like real-time testing, accelerated testing helps corporations predict a product’s shelf life earlier. Via ASLT, producers can obtain a deliberate product launch, having obtained a well timed and dependable expiration date for the product. As well as, the method ensures producers have enough details about the product’s high quality which varieties a part of routine audits and inspections.

Improved Packaging and Storage

A product’s packaging and storage go an extended approach to decide its general high quality. With out correct storage, micro organism could enter the product and quickly facilitate degradation.

Fortunately, the fast outcomes from accelerated testing will help corporations decide the most effective storage and packaging circumstances. When product producers know learn how to retailer a product appropriately, they will keep away from unhealthy storage and protect the product’s freshness.

Accelerates Product Innovation

The high-stress ASLT circumstances guarantee a fast degradation of a product’s high quality, elevating the shelf life testing time.

Subsequently, producers can have sufficient time to collect the mandatory information when creating a brand new product. Furthermore, producers can eradicate any vital elements early within the growth stage earlier than releasing the product. The web impact of the system is an accelerated innovation course of that helps the corporate save on the price of manufacturing.

Determines the Excessive Situations of Product High quality

Throughout accelerated shelf-life testing, a product undergoes varied degradation steps. Typically, scientists could choose to retailer a product beneath excessive circumstances that don’t match common storage circumstances. Scientists will then have a chance to look at how the product reacts to totally different conditions.

The data is vital if producers want to grasp how a product behaves beneath totally different storage circumstances. As an illustration, merchandise destined for areas with high-temperature fluctuations could require accelerated shelf-life testing earlier than dispatch.

Protects Enterprise Popularity

As beforehand talked about, product producers who use accelerated testing profit from the fast prediction of shelf life. Subsequently, the method eliminates the danger of dispatching low-quality merchandise into the market. Producers can due to this fact preserve at bay buyer complaints arising from high quality points.

Furthermore, ASLT provides prior insights into the widespread inhibitors of shelf life, which producers can mitigate in the course of the product’s innovation. The result’s an optimized manufacturing course of that ensures high-quality merchandise.
