Food Simulant Formulation and Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Test food simulants were formulated to contain organic acids commonly found in foods/juices and those used as ingredients in fruit-flavored beverages (Shui and Leong 2002 (link); Yoshikawa et al. 2007 (link)). Food simulants consisted of DI water (control), 3% citric acid (w:w), 3% malic acid (w:w), and 3% acetic acid (w:w). Acid concentration of the food simulants (3%) was based on guidance from governmental bodies for testing migration of chemical contaminants from food packaging materials (US Food and Drug Administration 2007 ; European Commission 2011 ). Measurement of food simulant pH was performed using a calibrated S20 SevenEasy pH meter with InLab Routine Pro pH electrode (Mettler Toledo, Columbus, OH).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
