The search for the consumption of foods with functional potential has increased, encouraging
by the need to improve the quality of life. In general studies show that
the group of bioactive compounds is one of the main responsible for several effects
beneficial to human health. Within this large group we can highlight the compounds
phenolics. These are considered one of the most common groups of phytochemicals, and
are defined as secondary metabolites that are derived from some metabolic pathways.
of the plants. In addition to the benefit to human health, these compounds are also
very important for the defense system of plants. Due to all these benefits
several techniques are used to study compounds of interest. Amongst them
we can highlight the paper spray technique that has gained visibility due to its
efficiency and simplicity of execution. In this context we aim in this chapter bring
a brief literature review on the subject using as a search tool
different scientific databases. 56 studies used for the
elaboration of this text. It was found that the technique is efficient and has been widely used
in food analysis and despite being a relatively new technique it is already well
established, having its use in a promising way.
