Alternative analytical techniques and in vitro digestion assays to special foods

Abstract

The research project aims to presents the application of alternative analytical techniques, considered emerging, such as near infrared spectroscopy, UV-visible spectrophotometry associated with chemometric tools for the evaluation of the potential for discrimination of special, green and roasted canephore coffees, produced in different regions of Brazil and fraud detection; and perform in vitro digestion assays to assess the bioaccessibility of essential elements in plant based foods and organic and A2 milk and correlate with some components of the products, both as an unpublished proposals. It is a continuation of the projects carried out by the research group, with the use of new matrices and different applications of spectroanalytic techniques and the simulation of in vitro digestion. Recently, 30 scientific manuscripts, in addition to a patent deposit, an award at an international congress, were obtained as results of this line of research. Fine/special coffee, plant based and organic foods were named as "special" in the project title, as they differ from traditional "similars". The techniques considered alternative, are associated with green analytical chemistry, allow direct analysis, with quick answers, after performing exploratory analysis and building classification or multivariate calibration models. However, studies with special canephore coffees as a new application are unprecedented and will contribute to the growth of the market for this product, including indigenous coffees produced in Rondônia. In another context, data on the availability of essential elements, whose deficiencies are considered serious worldwide public health problems, in special foods indicated the basis for nutritional assessments and contribute with relevant considerations regarding possible or expected benefits or healthiness associated with the consumption of these differentiated products.
