Moisture content of food is the most important quality parameter in the food industry that has a significant impact on food shelf life, food texture, food taste, and stability to microbes. High moisture level in the products is killing the Moroccan food processing industry. Today, moisture analyzers are in urgent demand by the Moroccan industries.
Microbial spoilage of products is likely to occur in products with a high level of moisture, and less moisture affects the texture and weight of products. This has a direct impact on profitability. The measurement of moisture content is critical to the manufacturer, as it can lead to the rejection of a batch and the discontent of customers.
Moroccan food processing is oriented towards the production of more valuable processed foods.
A moisture analyzer is a laboratory testing instrument that measures the moisture content in food by the loss in weight of heating at a certain temperature over a set period of time.
Moisture analyzers find a wide application in food industry quality control laboratories in Morocco. It is also considered to be a mixture of weighing technology and heating systems. It renders extremely fast and precise results.
Different types of moisture analyzers include:
Most of these systems are based on the use of halogen, the most commonly used because of its speed and accuracy.
1. Ensures Product Stability
Checks microorganism proliferation and excludes decay.
2. Maintains Product Quality
Encourages texture, taste, and consistency.
3. Supports Regulatory Compliance
Helps comply with food safety requirements of local and export markets.
4. Reduces Material Loss
Maximizes dry processes and eliminates excessive drying.
5. Improves Process Efficiency
Allows real-time modifications on the production.
A moisture analyzer machine is based on the thermogravimetric principle, in which the moisture content is calculated by measuring the weight lost during heating.
Step-by-Step Operation
1. Sample Placement
A small quantity of the food sample is placed on the weighing pan.
2. Initial Weighing
The instrument measures the initial weight of the sample.
3. Controlled Heating
The sample is heated using a halogen or infrared source.
4. Moisture Evaporation
Moisture evaporates while solids remain.
5. Final Weight Measurement
The analyzer records the final weight after drying.
6. Moisture Calculation
Moisture content is determined as the percentage of weight loss.
Technical Insight
The heating profile (time and temperature) has a significant role to play in the correct results. The wrong settings may result in sample drying or thermal spoilage, hence inaccurate measurements.
One of the manufacturers of high-quality moisture analyzers in Morocco, such as Presto Instruments, provides the following:
Benefits
1. Loss on Drying (LOD)
The most common method is where moisture is calculated based on weight loss.
2. Karl Fischer Titration
Used for precise moisture determination in low-moisture samples.
3. Infrared Drying
Heats very fast with the aim of quicker results.
4. Microwave Drying
Suitable for specific food products requiring uniform heating.
Among these, LOD using a moisture analyzer machine is the most widely adopted technique in industrial applications.
F&B Manufacturing Industry
Moisture content in grains, snacks, dairy, and processed food.
Agriculture
Assessment of moisture in seeds and crops.
Pharmaceuticals
Maintaining appropriate moisture contents of medications.
Packaging
Determining the amount of moisture in packaging material.
Chemical Industry
Hydraulic tests on powders and raw material.
A reliable moisture analyzer in Morocco ensures compliance with:
Conformity to standards delivers internationally recognized and true results. Detailed guidelines are given by ASTM International and AOAC.
Common Challenges
1. Sample Inconsistency
A non-uniform sample will provide inaccurate results.
2. Incorrect Temperature Settings
May cause incomplete drying or sample degradation.
3. Volatile Compounds Interference
Loss of non-water volatiles can affect readings.
4. Environmental Factors
Measurements can be affected by humidity and airflow.
5. Calibration Issues
Poor calibration reduces accuracy.
