When Does a Food Manufacturer Need a Water Activity Meter? Malaysia
When Does a Food Manufacturer Need a Water Activity Meter? Malaysia
Does every food manufacturer need a Water Activity Meter?
Not necessarily.
The decision should depend on the product, QA/QC requirements, customer specifications, product-development needs and the type of quality information the manufacturer wants to monitor.
For companies that specifically need water activity or Aw measurement, a dedicated instrument such as the Landtek WA-60A Water Activity Meter can be considered.
Here are several situations where a food manufacturer may need to introduce water activity testing.
1. YOUR PRODUCT SPECIFICATION REQUIRES AW
This is one of the clearest reasons to use a Water Activity Meter.
If an internal specification, customer requirement or established testing procedure specifically requires:
Water Activity
or
Aw
then a moisture meter alone does not provide the same measurement.
Water activity and moisture content are related, but they are different parameters.
2. YOU ARE DEVELOPING A NEW FOOD PRODUCT
R&D teams often compare multiple formulations before finalizing a product.
For example:
Formula A
Formula B
Formula C
The team may compare characteristics such as:
• Taste
• Texture
• Appearance
• Moisture content
• Water activity
• Packaging performance
• Storage behavior
Recording Aw provides another quantitative parameter for product comparison.
3. YOU ARE CONDUCTING SHELF-LIFE STUDIES
Shelf life depends on multiple factors.
These can include:
• Formulation
• Processing
• Packaging
• Storage temperature
• Storage humidity
• Microbiological factors
• Chemical changes
• Physical changes
Water activity can be one parameter within a broader shelf-life evaluation program.
For example, QA/QC or R&D personnel may record Aw at different stages during a storage study and compare the results with other product-quality observations.
4. YOU NEED BETTER BATCH-TO-BATCH COMPARISON
If the same product is manufactured regularly, measurable parameters can help monitor production consistency.
A company may establish a procedure such as:
Batch 001 – Record Aw
Batch 002 – Record Aw
Batch 003 – Record Aw
Batch 004 – Record Aw
Results can then be compared with the manufacturer's established specification or historical data.
5. YOU MANUFACTURE DRIED OR LOW-MOISTURE PRODUCTS
Depending on the specific product and quality requirement, water activity measurement may be useful for products such as:
• Biscuits
• Cookies
• Crackers
• Snacks
• Dried foods
• Nuts
• Grains
• Spices
• Powdered foods
• Confectionery
• Food ingredients
A product appearing "dry" does not mean that water activity and moisture content are automatically the same measurement.
6. YOU ARE CHANGING YOUR FORMULATION
Changing an ingredient can affect more than taste.
It may also change the way water interacts with the product.
During formulation trials, Aw measurements can provide additional information when comparing the original and modified products.
7. YOU ARE TESTING NEW PACKAGING OR STORAGE CONDITIONS
Packaging and storage studies may involve comparing samples after different periods or under different conditions.
Water activity can be recorded together with other relevant product parameters during these trials.
This can help QA/QC and R&D teams build a more complete picture of product behavior.
DO YOU NEED A WATER ACTIVITY METER OR MOISTURE METER?
Before purchasing, ask one important question:
"What parameter do I actually need?"
If the requirement is Moisture %, you may require a moisture measurement method.
If the requirement is Aw, you need water activity measurement.
Do not purchase based only on the general description of "measuring water in food."
Confirm the actual parameter first.
WHEN MAY YOU NOT NEED A WATER ACTIVITY METER?
If your company has no Aw requirement and your existing quality-control procedure only requires other parameters, purchasing a Water Activity Meter may not be necessary.
It is better to identify the testing requirement first rather than buying an instrument simply because other food manufacturers use one.
The correct instrument should solve an actual measurement requirement.
LANDTEK WA-60A WATER ACTIVITY METER
The Landtek WA-60A is designed for water activity measurement and can be considered for suitable applications in:
• Food manufacturing
• Food processing
• QA/QC
• R&D
• Bakery production
• Snack manufacturing
• Dried food processing
• Food laboratories
• Universities and research facilities
Before purchasing, confirm that Aw is the parameter required for your application.
NOT SURE WHETHER YOUR FACTORY NEEDS A WATER ACTIVITY METER?
Send MTM Precision the following information:
• What product do you manufacture?
• What sample do you need to test?
• Does your specification require Aw or moisture content?
• Is the testing for production QC, R&D or shelf-life studies?
• How frequently will you perform the test?
We can help check whether a Water Activity Meter such as the Landtek WA-60A is appropriate for your requirement.
