Comprehensive Guide to ISO 21527-1 Yeast Enumeration in Juices Laboratory Testing Service Provided by Eurolab

ISO 21527-1 is a widely recognized international standard for yeast enumeration in juices, developed and published by the International Organization for Standardization (ISO). The standard provides a harmonized method for measuring the number of yeast cells present in fruit and vegetable juices.

The legal and regulatory framework surrounding this testing service is governed by various national and international standards. In the European Union, for example, Regulation (EC) No 1333/2008 on food additives requires that all foods intended for human consumption be safe and comply with specific requirements. Similarly, the Codex Alimentarius Commission sets international food safety standards, including those related to yeast enumeration in juices.

The relevant standard development organizations include:

  • International Organization for Standardization (ISO)
  • European Committee for Standardization (CEN)
  • American Society for Testing and Materials (ASTM)
  • Turkish Standards Institution (TSE)
  • Standards evolve and get updated regularly to reflect new scientific knowledge, technologies, and regulatory requirements. For example, ISO 21527-1 was revised in 2017 to improve the accuracy and reliability of yeast enumeration results.

    Some specific standard numbers and their scope are:

  • ISO 21527-1:2017 - Yeast enumeration - Part 1: Fruit juices
  • EN 13905:2010 - Foodstuffs - Determination of microorganisms - Detection and enumeration by colony counting technique
  • ASTM E2695-09 - Standard Test Method for Enumeration of Microorganisms in Fruit Juice
  • Standard compliance is a critical aspect of the testing service, particularly for industries such as food and beverage processing. Non-compliance can result in product recalls, financial losses, and damage to reputation.

    The specific test is needed because yeast enumeration in juices is crucial for ensuring product safety and quality. Yeast can cause spoilage, fermentation, and other problems that affect the taste, texture, and shelf life of juices.

  • Humidity: 50-60
  • Pressure: atmospheric pressure
  • Lighting: dim, indirect lighting
  • Sample preparation procedures involve:

  • Homogenization of sample
  • Dilution of sample (if necessary)
  • Sterilization of equipment and reagents
  • Testing parameters and conditions include:

  • Temperature: 20-25C
  • Incubation time: 48-72 hours
  • Media: yeast-enriched agar or broth
  • Measurement and analysis methods involve:

  • Counting of colony-forming units (CFU)
  • Calculation of yeast cell concentration
  • Statistical analysis of results
  • Calibration and validation procedures are performed regularly to ensure the accuracy and reliability of test results. This includes:

  • Calibration of equipment using certified standards
  • Validation of analytical methods using certified reference materials
  • Regular maintenance and calibration of equipment
