SPIFAN Meeting (September 17, 2016)

95 / 112

Microwave digestion/Cloud Point Extraction/ Spectrophotometry11
• Alternative to F-ISE or IC detection
• LOQ blank: 5 μg/L / LOQsample: 25 μg/100g dry matter (1g with DF=50) / 20 food samples
(fruit juices, soups, babyfoods: 0.01 – 28 mg/100g) /RSDr < 5% / Recovery : 97% -103%
• Not validated for infant formula: (estimated LOQ : < 20 μg/100g RTF)
Conclusion: feasibility to test for Infant Formula

TMFS derivatization / GC-FID (Poster AOAC meeting 2015)
• Alternative to F-ISE, IC detection and spectrophotometry
• LOQ sample: 30 μg/100g dry matter (3 μg/100g RTF) / 2 samples (powdered and liquid IF)
/ RSD = 6% / Recovery : 87% -101%
Conclusion: SLV to perform with SPIFAN kit
