Structural study of N-(1,3-Benzothiazol-2-yl)-4-Halobenzenesulfonylhydrazides: ...
Gomes, Lígia Rebelo; Low, John N.; Pinheiro, Alessandra C.; Wardell, James L.Hydrazonylsulfones such as Bt-NHNHSO2R and their iminotautomers have been studied as optical materials and for their biological potential. In this work, a structural study has been carried out on N-(1,3-benzothiazol-2-yl)-4-(halogenobenzenesulfonyl)-hydrazides (1: X = F, Cl, Br). For (1: X = F), single-crystal X-ray diffraction, Hirshfeld surface analysis, and PIXEL calculations were conducted, while in (1: X =...
Determination by ICP-MS of essential and toxic trace elements in gums and carra...
Azevedo, Rui; Oliveira, Ana Rafaela; Almeida, Agostinho; Gomes, Lígia RebeloGums and carrageenans are food additives widely used in food preparations to improve texture and as viscosifiers. Although they are typically added in small amounts, nowadays people tend to use more and more pre-prepared food. In this work, the content of a wide panel of trace elements in commercial products were analyzed. Carrageenans and gums (n = 13) were purchased in the Portuguese market and were from Euro...
Effect of extraction methodology on the phytochemical composition for camelia s...
Barreira, Sérgio; Silva, André M. N.; Moutinho, Carla; Seo, Ean-Jeong; Hegazy, Mohamed-Elamir F.; Efferth, Thomas; Gomes, Lígia Rebelo(1) Background: beverages based on extracts from Camellia sinensis are popular worldwide. Due to an increasing number of processed teas on the market, there is a need to develop unified classification standards based on chemical analysis. Meanwhile, phytochemical characterizations are mainly performed on tea samples from China (~80%). Hence, data on teas of other provenances is recommended. (2) Methods: in the ...

Phytochemical characterization and biological activities of green tea (Camellia...
Barreira, Sérgio; Moutinho, Carla; Silva, André M.N.; Neves, José Manuel Gomes da Silva; Seo, Ean-Jeong; Hegazy, Mohamed-Elamir F.; Efferth, ThomasBackground: Green tea is not only one of the most widely consumed beverages worldwide, but is also known for its health promoting and therapeutic effects. Green tea is cultivated in areas with high humidity and acidic soils in China, Indonesia and Japan. Those places have well-marked dry and rainy seasons. In opposite, Azores have a climate with constant average annual rainfall and, unlike eastern regions, rela...
Demystifying emulsifiers as additives through molecular gastronomy: a contribut...
Gomes, Lígia Rebelo; Silva, Cláudia; Simões, Catarina D.According to the Food and Agriculture Organisation of the United Nations, one third of food produced annually for human consumption results in food losses or wastage, which is environmentally degrading, economically unviable, ethically incorrect, and does not contribute to sustainable development. The use of additives can help prevent the waste of food that is still fit for consumption in a world where about 16...

Demystifying thickener classes food additives though molecular gastronomy
Gomes, Lígia Rebelo; Simões, Catarina D.; Silva, CláudiaIn order to meet the nutritional needs of the increasing world population, a higher demand for food production seems to be imperative. This challenge is peremptory because it is necessary to find sustainable forms of production that have, in one hand, to meet the requirements of safety and quality and, simultaneously, the increase in demand. One way to achieve such a goal is to reduce waste along the food suppl...
Recent approaches on signal transduction and transmission in acupuncture: a bio...
Gomes, Lígia Rebelo; Leão, PedroAcupuncture is one of the areas among the alternative therapies that arouses high curiosity in the biomedical scientific community. It is particular popular for treatment of chronic diseases and addictions. However, contrasting with its evidence based effectiveness, the lack of a reasonable explanations for its mode of action divides that scientific community. Difficulties also arise to those responsible for pr...
