Chemical and Antioxidant Properties of Solvent and Enzyme-Assisted Extracts of and .

Extraction strategies impact the efficiency and nature of extracted compounds. This work assessed the chemical composition and antioxidant capacity of ethanolic, hydroethanolic, and aqueous versus enzyme-assisted extracts (isolated or with the sequential use of alcalase, cellulase, and viscozyme) of the macroalgae (brown, ) and (red, . For both macroalgae, enzyme-assisted extraction (EAE) was the most efficient process compared to solvent-assisted extraction (SAE), independent of solvent.

Chemical Composition and Antioxidant Potential of Five Algae Cultivated in Fully Controlled Closed Systems.

In this study, the chemical composition and antioxidant profile of five edible macroalgae, , , , , and , cultivated in fully controlled closed systems, were determined. Protein, carbohydrates, and fat contents ranged between 12.4% and 41.

It comes from the sea: macroalgae-derived bioactive compounds with anti-cancer potential.

Nature derived compounds represent a valuable source of bioactive molecules with enormous potential. The sea is one of the richest environments, full of skilled organisms, where algae stand out due to their unique characteristics. Marine macroalgae adapt their phenotypic characteristics, such as chemical composition, depending on the environmental conditions where they live.

Bioactive Hydrolysates from : Optimal Process and Bioactive Properties.

Microalgae have been described as a source of bioactive compounds, such as peptides. Microalgae are easy to produce, making them a sustainable resource for extracting active ingredients for industrial applications. Several microalgae species have interesting protein content, such as with around 52.

Glyphosate in Portuguese Adults - A Pilot Study.

Background: Glyphosate is a broad-spectrum biocide and the active ingredient in the most widely used herbicides worldwide. Since 2015, when the International Agency for Research on Cancer classified it as a Class 2A carcinogen, global interest in this chemical spiked particularly as regards exposure of the general population.

Objective: An exploratory glyphosate exposure assessment was conducted among Portuguese adults.

Health benefits and bioavailability of marine resources components that contribute to health

The strict connection between nutritional intake and health leads to a necessity of understanding the beneficial and protective role of healthy nutrients and foods. The marine environment is a source of a plethora of many organisms with unique properties, extremely rich in bioactive compounds and with remarkable potential for medical, industrial and biotechnological applications. Marine organisms are an extreme valuable source of functional ingredients such as polysaccharides, vitamins, minerals, pigments, enzymes, proteins and peptides, polyunsaturated fatty acids (PUFA), phenolic compounds and other secondary metabolites that prevent or have the potential to treat several diseases given their cardiovascular protective, anti-inflammatory, anti-hypertensive, anti-oxidant, anti-coagulant, anti-proliferative and anti-diabetic activities.

Urban organic community gardening to promote environmental sustainability practices and increase fruit, vegetables and organic food consumption.

Objective: To describe the environmental practices of participants in an urban organic community garden at the beginning of their gardening experience and after a period of six months, and to discover their opinion about how this activity influenced the consumption of vegetables, fruits and organic food.

Method: Interviews using structured questionnaires were conducted twice with 115 city dwellers: when they started in the vegetable garden and about 6 months later. The questionnaire included questions related to environmental practices.
