dc.description.abstract | Berries represent one of the most important and high-valued group of modernday health-beneficial “superfoods” whose dietary consumption has been recognized to be beneficial for human health for a long time. In addition to being
delicious, berries are rich in nutrients, vitamins, and several bioactive compounds, including carotenoids, flavonoids, phenolic acids, and hydrolysable tannins. However, due to their high value, berries and berry-based products are
often subject to fraudulent adulteration, commonly for economical gain, but also
unintentionally due to misidentification of species. Deliberate adulteration often
comprises the substitution of high-value berries with lower value counterparts
and mislabeling of product contents. As adulteration is deceptive toward customers and presents a risk for public health, food authentication through different methods is applied as a countermeasure. Although many authentication
methods have been developed in terms of fast, sensitive, reliable, and low-cost
analysis and have been applied in the authentication of a myriad of food products and species, their application on berries and berry-based products is still
limited. The present review provides an overview of the development and application of analytical chemistry methods, such as isotope ratio analysis, liquid and
gas chromatography, spectroscopy, as well as DNA-based methods and electronic
sensors, for the authentication of berries and berry-based food products. We provide an overview of the earlier use and recent advances of these methods, as well
as discuss the advances and drawbacks related to their application. | en_US |
