Microalgae are widely used as food supplements due to their high protein content, essential fatty acids and amino well carotenoids. The addition of microalgal biomass products (e.g., baked confectioneries) is a common strategy attract novel consumers. However, organoleptic factors such color, taste smell can be decisive for the acceptability foods supplemented with microalgae. aim this work was develop chlorophyll-deficient mutants Chlorella vulgaris by chemically induced random mutagenesis...
Among the most significant and productive agroindustries worldwide is wine business. This agroindustry generates millions of tons biological residues, carrying huge negative impacts related to disposal these materials into environment. Nevertheless, byproducts present a high potential for developing new products, contributing circularity this economic sector. In study, chemical composition grape pomace (GP) obtained from vinification process (2018 campaign).) red grapes Portuguese cultivar...
A crescente demanda por sustentabilidade e eficiência na mineração impõe desafios à engenharia, especialmente no aproveitamento integral de produtos, subprodutos rejeitos. O descarte inadequado desses materiais representa não apenas um custo elevado, mas também impacto ambiental significativo. Diante desse cenário, este estudo investiga estratégias para otimizar a das plantas beneficiamento, reduzir desperdícios agregar valor aos da mineração. Para isso, foram analisadas abordagens...
Biomass harvesting is one of the most expensive steps whole microalgal production pipeline. Therefore, present work aimed to understand effect salinity on growth performance, biochemical composition and sedimentation velocity Tetraselmis sp. CTP4, in order establish an effective low-cost pilot-scale system for this strain. At lab scale, similar performance was obtained cultures grown at salinities 5, 10 20 g L-1 NaCl. In addition, identical settling velocities (2.4-3.6 cm h-1) were observed...
The objective of this study was to elaborate liposomes, through the lipid film hydration methodology, nanoencapsulate phenolic compounds Spirulina LEB-18 and Chlorella pyrenoidosa microalgae, evaluate their physicochemical characteristics storage stability for 21 days. total were evaluated using a calibration curve gallic acid methanol ethanol as extraction solvents. size polydispersity index nanovesicles determined by light scattering percentage encapsulation efficiency centrifugation...
Encapsulation can be used as a strategy to protect and control the release of bioactive extracts. In this work, an extract from Spirulina sp. LEB-18, rich in phenolic compounds, was encapsulated biopolymeric particles (i.e., composed alginate) characterized concerning their thermal behavior using differential scanning calorimetry (DSC), size, morphology, swelling index (S), encapsulation efficiency (EE%); profile compounds at different pHs particle under vitro gastrointestinal digestion were...
The crude soy and rice lecithin are used in studies of liposome formulation. They have been as flavor encapsulators, masking, antioxidants, nutrient protective against degradations the gastro intestinal tract. This study aimed to show importance its varied uses liposomes different areas. paper indicates lecithin, both purified (phosphatidylcholine) ones, feasible for encapsulation various materials, from medical pharmaceutical food ones. Key words: Lecithin, phospholipids, vesicles.
The object of the study was to evaluate proximate composition, amino acid profile, protein digestibility, quantification individual and total phenols antioxidant effect phenolic extracts Spirulina LEB-18 Chlorella pyrenoidosa front various methods. microalgae stand out on nutrient profile activity through different mechanisms, most important being scavenging free radicals, which depends structure compound involved. Microalgae were evaluated for aminogram, digestibility in vitro, extraction...
Nowadays, there is an increasing demand for novel feedstocks and alternative protein sources to meet global needs. Because of their rich nutritional profiles high contents, microalgae-based food products supplements are being developed. Nonetheless, these present organoleptic characteristics such as taste, smell colour that often considered unpleasant by human animal consumers. To address this constraint, strain improvement approaches random mutagenesis have been used, which combined with...
In humans, the normal metabolic activity produces free radicals that constantly, along with other risk factors, including hypercholesterolemia may be responsible for onset of degenerative diseases. Some bioactive compounds present in blackberry (Rubus spp.) have ability to act as natural antioxidants can make food minimize effects on body caused by reactive oxygen species.This study verified benefits nectar through quantification triglycerides, total and fraction cholesterol HDL (high...
Thraustochytrids have gained increasing relevance over the last decades, due to their fast growth and outstanding capacity accumulate polyunsaturated fatty acids (PUFAs), particularly docosahexaenoic acid (DHA). In this context, present work aimed optimize performance DHA yields by improving culture medium of Aurantiochytrium sp. AF0043. Accordingly, two distinct media were optimized: (i) an inorganic optimized (IOM), containing only monosodium glutamate glucose as nitrogen carbon sources,...

The purpose of this study was to assess the extraction cellulose from stalks vines using auto-hydrolysis and characterize it. As results obtained, colorimeter readings displayed a final yellow color fiber, demonstrating that bleaching process insufficient multiple processes might be required. According FTIR (Fourier-transform infrared spectroscopy) data, there were stretching deformation vibrationsof characteristic peak represent (2900, 1500, 1200 cm−1). Although lignin hemicellulose...

Microalgal biomass has gained increasing attention in the last decade for various biotechnological applications, including human nutrition. Certified organic products are currently a growing niche market which food industry shown great interest. In this context, work aimed at developing certified culture medium production of autotrophic Chlorella vulgaris biomass. A preliminary assay 2 L bubble column photobioreactors was performed order to screen different commercial substrates (OS)...
Facial rejuvenation is a popular procedure to temporarily mask the effects of aging. Most patients desiring this treatment are younger and want improvement without any down time. This study was conducted evaluate use Er:YAG laser as facial tool.The full faces 18 volunteers were treated with an using fluence either 5 or 10 J/cm2. All applied EMLA cream (lidocaine 2.5% prilocaine 2.5%) two hours before single pass pulse duration about 300 microseconds. Follow-up visits made in order degree...
