| Anmerkungen | ptAI01 (2027) Lactose + Fructose in "lactose-free" (< 100 mg/100 g) and „lactose-reduced“ (> 100 mg/100 g and ≤ 1000 mg/100 g) Cereal Pap Powder for Children [Samples A + B] and "Recovery Reference Sample“ [RS] Elicitors of Allergies and Intolerance Reactions PTs (qualitative / quantitative) Test items: 2 different food matrix samples A + B (25 g each) + 1 recovery reference sample RS (spiked Rice Flour, 25 g) Methods: All suitable methods can be applied. Procedure: There are two different samples A and B containing the parameters lactose and fructose to be determined. One of these samples contain lower levels and the other higher levels of lactose ("lactose-free" with < 100 mg/100g and „lactose-reduced“ with > 100mg/100g and ≤ 1000mg/100g, respectively). The third, "recovery reference sample", was prepared adding the parameters lactose and fructose in a simple matrix (rice flour) in similar amounts like the lower spiked food matrix sample without further processing. Evaluation: The evaluation is carried out qualitatively (positive/negative) for lactose and from a total of 5 results on quantitatively for lactose and fructose. It includes kernel density estimation, outlier tests, robust mean, robust standard deviation and z-scores. The assigned value is the robust mean of participants results.
