The generally recognized as safe (GRAS) microalgae Haematococcus pluvialis (wet...
Castillo, Aly; Finimundy, Tiane C.; Heleno, Sandrina A.; Rodrigues, Paula; Fernandes, Filipa Alexandra; Pereira, Simón; Lores, Marta; Barros, LillianThis work proposes the application of astaxanthin-rich H. pluvialis wet paste (HPW) as a partial substitute for wheat flour in the preparation of filloas, a dish that combines the basic ingredients of industrial bakery. The nutritional and color profile of HPW-enriched samples was evaluated by comparative analysis with a mixture of synthetic food dyes. The highest content of carotenoids (798 ± 12 µg g−1) and fatty...
First approach to assess the effects of nanoplastics on the soil species Folsom...
Barreto, Ângela; Santos, Joana; Almeida, Lara; Tavares, Vítor; Pinto, Edgar; Celeiro, Maria; Garcia-Jares, Carmen; Maria, Vera L.The terrestrial environment is one of the main recipients of plastic waste. However, limited research has been performed on soil contamination by plastics and even less assessing the effects of nanoplastics (NPls). Behind the potential toxicity caused per se, NPls are recognized vectors of other environmental harmful contaminants. Therefore, the main aim of the present study is to understand whether the toxicit...
The chemistry behind the body art: unveiling the elemental profile and heavy me...
Rubio, Laura; Barrulas, Pedro; Costa, Mafalda; Garcia-Jares, Carmen; Lores, Marta; Barrocas Dias, CristinaTemporary tattoos and dyes are increasing popularity as an alternative to permanent ones. However, knowledge on its elementary composition is scarce and, this scientific gap can potentially make them a source of heavy metal exposure on humans. The present research aimed to explore the possibility of using the inorganic chemical signature to characterize natural pigments-based products and to evaluate the heavy ...
Understanding the chemical and mineralogical composition of commercial henna an...
Rubio, Laura; Costa, Mafalda; Barrulas, Pedro; Lores, Marta; Garcia-Jares, Carmen; Barrocas Dias, CristinaTemporary tattoos and dyes constitute a great analytical challenge in relation to the regulatory control of their ingredients. Most of these commercial products are not labeled according to their content and their chemical nature is highly diverse. Therefore, it is necessary to analyze these complex samples to evaluate the potential presence of metallic impurities, to ensure the safety of cosmetic products cont...
Novel incorporation of red-stage haematococcus pluvialis wet paste as a coloura...
Castillo, Aly; Finimundy, Tiane C.; Heleno, Sandrina A.; Rodrigues, Paula; Fernandes, Filipa Alexandra; Pereira, Simón; Garcia-Jares, CarmenHaematococcus pluvialis Flotow is a microalga used as a nutraceutical, due to its high content in bioactive compounds, mainly carotenoids, in which astaxanthin stands out [1]. Furthermore, H. plu- vialis has shown a high antioxidant potential, and combined with its intense red colour, this microalga could have dual functionality: as a colourant and a bioactive ingredient [ 2]. The process to obtain this ingredi...
