DNA-Based Verification of Yogurt Starter Cultures to Support Label Compliance
Purity-IQ tested 16 commercial yogurt products using targeted DNA-based PCR to verify the two starter culture species required for yogurt labeling. The methods reliably detected Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus across diverse matrices. These findings support DNA-based verification as a scalable tool for label compliance and quality assurance.
