Fruit Juice VOC Testing

Ensuring food safety and quality is paramount in the fruit juice industry. One critical aspect of this is the testing of volatile organic compounds (VOCs), which can impact flavor, aroma, and overall product integrity. This service focuses on analyzing VOCs present in fruit juices to ensure compliance with international standards.

The process begins with precise sample preparation, where the juice is filtered and degassed to eliminate any interfering volatiles. Various analytical techniques are employed based on the specific requirements of the testing, including gas chromatography-mass spectrometry (GC-MS) for accurate identification and quantification of VOCs.

Understanding the standards and regulations governing VOC content is crucial. Compliance with international norms such as ISO 16025, ASTM D3960, and EN 14179 ensures that testing methods are reliable and reproducible. These standards provide robust guidelines for the extraction, quantification, and reporting of VOCs.

The significance of this service extends beyond mere compliance; it also enhances product quality by identifying potential issues early in the production process. Early detection allows for corrective actions to be taken promptly, thereby minimizing waste and maintaining consistency across batches.
