TIJOLOS DE TERRA CRUA ESTABILIZADOS COM FIBRAS DE COCO VERDE: ALTERNATIVA PARA HABITAÇÃO DE INTERESSE SOCIAL

Este trabalho propõe a utilização da fibra de coco verde incorporada à terra crua como material alternativo na construção de tijolos de adobe. As fibras foram cedidas a partir de uma parceria com a EMBRAPA, onde é produzido em sua Unidade de Beneficiamento da Casca do Coco Verde cerca de 530 t/a de fibra bruta. A fibra inserida ao adobe tem características de agir como um esqueleto principal devido à presença de celulose, lignina e hemicelulose atuarem conferindo uma maior coesão entre os componentes. Como base metodológica, adotou-se Battistelle (2002). Foram confeccionados 8 tijolos com fibras no traço de 10% em volume e 8 tijolos sem fibras (solo) como amostra de referência e realizou-se o ensaio de compressão simples segundo as normas brasileiras de tijolo maciço de barro cozido (NBR 6460/83 e NBR 8492/84), devido à inexistência de uma norma específica para os tijolos de terra crua. Os tijolos com a presença de fibras obtiveram aumento de 25% na resistência em relação à amostra de referência. Pode-se inferir que a utilização da fibra do coco verde incorporada ao adobe é uma alternativa viável economicamente para a construção de habitações de interesse social. ---------------------------------------------This assignment proposed the use of green coconut fiber built to land as raw material alternative to the construction of adobe bricks. The fibers were donated by EMBRAPA, thru a partnership, where it is produced in its Benefaction of the Bark of Green Coconut Unit approximately of 530 tones/year of crude fiber. The fiber inserted to adobe acts as a main structure due to the presence of cellulose, lignin and hemicellulose act giving greater cohesion between the components. As methodological basis, Battistelle (2002) was adopted. 8 bricks with fiber in 10% in volume and 8 bricks without fiber sample (soil) were manufactured as a reference and the Standart Compression test took place according with the Brazilian brick mass of baked clay Standart (NBR 6460/83 and NBR 8492/84), once there is not a specific standard to the bricks of raw land. The bricks with the presence of fiber obtained increase of 25% in the resistance comparing to the reference sample. One can infer that the use of fiber of green coconut incorporated to the adobe bricks is a viable alternative to the development of houses benefit social.fibra de coco, arquitetura de terra, cadeia agroindustrial do coco, coconut fiber, raw earth construction, agro-industrial chain of green coconut, Crop Production/Industries,

Unravelling the behavior of nanostructures during digestion and absorption

The food industry is increasingly focused on preventing nutrition-related diseases and improving consumers’ wellbeing. As a result, there is a growing trend towards healthy foods, enriched with bioactive compounds (such as vitamins, probiotics, bioactive peptides and antioxidants) produced through the application of innovative and safe technologies. In this context, the development of novel delivery systems for food applications through the use of nanotechnology has been extensively explored [1]. In fact, the encapsulation of bioactive compounds in bio-based nanostructures have been reported as promising mean of protecting the valuable bioactive compounds and providing new functionalities (e.g. increase of bioavailability). However, the use of very small particle sizes may alter the biological fate of the ingested materials and bioactive compounds, which could potentially have adverse effects on human health [2]. Therefore, the emerging field of nanotechnology offers new challenges to food industry not only by offering novel tools to improve food quality and human health, but also by introducing questions about nanostructures’ behaviour within the human body. The challenges that must be overcome before nanotechnology can be entirely embraced by food industry, includes the optimisation of nanostructures’ formulations to increase stability and bioactive compounds’ bio availability and the risk assessment of their use in food. The understanding of the behaviour of different nano-based delivery systems (e.g. nanoemulsions, nanoparticles) under digestion conditions, assessing their efficiency and safety is therefore of utmost importance to enable its widespread application in the food industry. This evaluation can be challenging, however, there are opportunities to take advantage from the lessons learned from pharmaceutical industry and of the considerable progress in the development of more realistic in vitro models to more accurately predict the behaviour of bio-based nanostructures once ingestedinfo:eu-repo/semantics/publishedVersio

Lipid-based nanostructures as strategies to enhance curcumins bioavailability: effect of carrier oil physical state

This study was supported by the Portuguese Foundation for Science and Technology (FCT) under the scope of the Project PTDC/AGR-TEC/5215/2014, the strategic funding of UID/BIO/04469/2019 unit and BioTecNorte operation (NORTE-01-0145-FEDER-000004) funded by the European Regional Development Fund under the scope of Norte2020 - Programa Operacional Regional do Norte.info:eu-repo/semantics/publishedVersio

Incorporation of solid lipid nanoparticles into stirred yogurt: effects in physicochemical and rheological properties during shelf-life

The aim of this work was to develop a yogurt fortified with curcumin. Curcumin is a lipophilic compound with a wide range of biological activities; however, it presents low water solubility and low bioavailability, and therefore it was the first to be encapsulated in solid lipid nanoparticles (SLNs). Then the influence of the incorporation of curcumin-loaded SLNs on the physicochemical (i.e., pH, titratable acidity, syneresis and color) and rheological properties of yogurt during its shelf-life (30 days at 4 °C) was evaluated. SLN incorporation into yogurt did not affect pH and titratable acidity compared to the control (i.e., plain yogurt) during shelf-life, even though the yogurt with SLNs presented lower values of pH (4.25 and 4.34) and acidity (0.74% lactic acid and 0.84% lactic acid) than the control in the end, respectively. Furthermore, the yogurt with SLNs presented slightly higher values of syneresis than the control during the shelf-life; however, it did not present visual differences in whey separation. Relative to the color, the incorporation of SLNs into the yogurt imparted a strong yellow color to the sample but did not affect color stability during shelf-life. Both samples showed flow curves with yield stress and shear-thinning behavior during shelf-life, and, regarding the viscoelastic behavior, both showed a typical weak viscoelastic gel with an elastic structure. Overall, curcumin-loaded SLNs incorporation did not affect the physicochemical and rheological stability of yogurt during shelf-life, showing a promising application for the development of new functional foods.This study was supported by the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UIDB/04469/2020 unit and by LABBELS Associate Laboratory in Biotechnology, Bioengineering and Microelectromechanical Systems, LA/P/0029/2020.info:eu-repo/semantics/publishedVersio

Nanoemulsions for enhancement of curcumin bioavailability and their safety evaluation: effect of emulsifier type

This work aimed at evaluating the effects of different emulsifiers on curcumin-loaded nanoemulsions behavior during digestion, its safety and absorption, to develop nanoemulsions that provide safety and improved curcumin functionality. Nanoemulsions (NEs) were produced using two bio-based (lecithin (LEC) and rhamnolipids (RHAM)) and one synthetic (Tween®80 (TWE)) emulsifier at similar concentrations. Different NEs were subjected to in vitro digestion. The cytotoxicity and permeability tests were performed in Caco-2 cells. NE_TWE were stable during all phases of in vitro digestion, whereas NE_LEC and NE_RHAM were found to be unstable from the gastric phase. NE_TWE showed 100% of free fatty acids released, followed by NE_RHAM and NE_LEC. Curcumins bioaccessibility and stability increased in the following order: NE_LEC > NE_RHAM > NE_TWE. NE_LEC and NE_TWE did not show cytotoxic effects in any of the concentrations tested, while NE_RHAM presented high cytotoxicity in all concentrations tested. The apparent permeability coefficients were determined for NE_LEC and NE_TWE; however, the results were not statistically different. These results showed that the emulsifier used has a high impact on nanoemulsions behavior under the digestion process and on their cytotoxicity. This work contributed to the state-of-the-arts progress on the development of safer curcumin delivery systems with improved functionality, particularly regarding the proper selection of ingredients to produce said systems.This study was supported by the Portuguese Foundation for Science and Technology (FCT) under the scope of the strategic funding of UIDB/04469/2020 unit and under the scope of project PTDC/AGR-TEC/5215/2014.info:eu-repo/semantics/publishedVersio

Plant-based bigels for delivery of bioactive compounds: Influence of hydrogel:oleogel ratio and protein concentration on their physicochemical properties

Bigels are a class of soft matter systems with high potential in food industry as fortified ingredient replacers or food analogs. The aim of this work was to develop plant-based bigels using potato protein-based hydrogel and candelilla wax-based oleogel. The potato protein concentration and hydrogel:oleogel ratio effects on bigels production was assessed in terms of textural and rheological properties. The incorporation of curcumin and its bioaccessibility after in vitro digestion was also evaluated. All samples presented an oleogel-in-hydrogel structure arrangement. Increasing the protein concentration led to increased hardness and G*, improving the structure and consistency of bigels. The increase of oleogel fraction altered the distribution of oleogel droplets in the hydrogel matrix, affecting the hardness and the consistency of bigels. Overall, the increase of oleogel fraction and protein concentration allowed forming bigels with stronger mechanical properties and higher thermal resistance. The bigel showed a curcumin's bioaccessibility of 16.3 % and a curcumin's stability of 43.8 %, suggesting that this type of structures is promising for the delivery of bioactive compounds at the colon or for slow release of bioactive compounds. Overall, the results showed the possibility to develop potato protein-based bigels with interesting mechanical, rheological and thermal properties by changing the protein concentration and hydrogel:oleogel ratio, expanding the application of bigels in novel food products with high nutritional value and protein content, namely plant-based products.Raquel F.
