abstract = {Fruits and vegetables are a source of a wide range of nutrients, including bioactive compounds.
These compounds have great biological activity and have been linked to the prevention of
chronic non-communicable diseases. Currently, the food industry is developing new products to
introduce these compounds, whereby smoothies are becoming more popular among consumers. The
aim of this study was to evaluate the nutritional quality and the polyphenol and vitamin C content
of smoothies available on the Spanish market. An evaluation of the nutritional information and
ingredients was carried out. The phenolic compounds were determined by HPLC-ESI-TOF-MS; the
vitamin C content was quantified using HPLC-UV/VIS; and the antioxidant activity was analyzed by
DPPH and FRAP. Among all of the ingredients of the smoothies, coconut and banana have shown a
negative impact on the polyphenol content of the smoothies. In contrast, ingredients such as orange,
mango, and passion fruit had a positive correlation with the vitamin C content. Moreover, apple and
red fruits showed the highest positive correlations with most of the phenolic acids, flavonoids, total
phenolic compounds, and antioxidant activities. In addition, a clustering analysis was performed,
and four groups were clearly defined according to the bioactive composition determined here. This
research is a precious step for the formulation of new smoothies and to increase their polyphenol
quality.},
