Chemical Diversity of Polyphenols in Wine Red wine represents one of the most complex natural matrices for polyphenol analysis, containing over 200 different phenolic compounds that contribute to its color, flavor, stability, and health benefits. These compounds can be broadly categorized into flavonoids (including anthocyanins, flavan-3-ols, and flavonols) and non-flavonoids (such as hydroxybenzoic and hydroxycinnamic

1. Complexity of Fruit Juice Matrices Fruit juice analysis presents unique challenges due to the complex nature of these matrices. Unlike simple aqueous samples, fruit juices contain a diverse array of interfering compounds that can significantly impact LC-MS analysis. The primary matrix components include high concentrations of sugars (fructose, glucose, sucrose), organic acids (citric, malic,

Common Contaminants Found in Grains Grain products represent one of the most challenging matrices for food safety monitoring due to their susceptibility to multiple classes of contaminants. The primary contaminants of concern fall into three major categories: mycotoxins, pesticide residues, and heavy metals. Mycotoxins Mycotoxins are toxic secondary metabolites produced by fungi that commonly contaminate
