Summary The microalgae Chlorella vulgaris and Arthrospira platensis were evaluated as nutraceuticals. It was observed that is richer in saturated fatty acids ( FA ) monounsaturated . Within polyunsaturated PUFA ), n3 content below 1% sp over 10% This microalga had the lowest polyphenolic content. highest value found aqueous extract of , 334 ± 32 mg GAE per 100 g dw. Regarding DPPH only extracts yielded antioxidant activity with an inhibitory 80 1%. ABTS results showed stronger inhibition...
Microalgae are a valuable and innovative emerging source of natural nutrients bioactive compounds that can be used as functional ingredients in order to increase the nutritional value foods improve human health prevent disease. The marine microalga Isochrysis galbana has great potential for food industry ingredient, given its richness ω3 long chain-polyunsaturated fatty acids (LC-PUFAs), with high contents oleic, linoleic, alpha-linolenic acid (ALA), stearidonic, docosahexaenoic (DHA) acids....
The processing of tamarind pulp (Tamarindus indica L.) produces residues such as seeds, bark and fibers, which remain underused. Therefore, taking advantage fruit in the development new products is a technological alternative that can bring economic benefits to producers positively impact environment, leading more diversified products. A byproduct less known explored mucilage, neutral polysaccharide biopolymer derived from endosperm it has functions stabilization, emulsification, thickening,...
The brown seaweed Rugulopteryx okamurae is a major invasive species in Europe, menacing local ecosystems. challenge lies assessing application routes for this biomass, testing different extraction technologies (overnight agitation, mechanical homogenization, pH-shift, ionic liquid-, and ultrasound-assisted extractions) parameters. There was higher yield the extracts homogenized with 70% ethanol, especially 1:20, w/v, biomass–solvent ratio, than aqueous extracts. As to overnight ethanol...
Summary The Azorean macroalgae Petalonia binghamiae, Halopteris scoparia and Osmundea pinnatifida are undervalued require further study regarding their potential use as food. These three seaweed species had low fat contents, fatty acid (FA) profiles were characterised by a high proportion of saturated FA (SFA) in the case O. similar weights SFA polyunsaturated (PUFA) other two species. Within PUFAs, ω3 PUFAs most prominent P. binghamiae , yielding ω3/ω6 ratios that higher than one....
Microalgae have strong potential as novel sources of nutraceuticals, they contain significant amounts highly valuable bioactive compounds.
In vivo chlorophyll fluorescence measured by pulse amplitude modulated (PAM) fluorometry was used as an indicator of photosynthetic activity in tank-cultivated red algae [Gracilaria cornea and Asparagopsis armata (tetrasporophyte phase, previously known Falkenbergia rufolanosa)] using effluent seawater from sea bream fishponds (Sparus aurata). Optimal quantum yield indoor-grown G. did not change during the period analysed (2 months). contrast, optimal decreased drastically transferred indoor...
Summary The elemental composition and bioaccessibility of the Azorean macroalgae Petalonia binghamiae, Osmundea pinnatifida Halopteris scoparia were studied. H. had highest Cr, Mn, Co Ni contents. Iodine content was also in , 1098 ± 54 mg kg dw −1 . Content reductions due to rehydration 75%–90% range. Steaming led similar with exception Co, Zn O. For P. binghamiae percentages varied between elements. Variation culinary treatment narrower, particularly for Whereas I low 11%–14%, it reached...
The text assesses the occurrence of waterborne and foodborne diseases in Brazil 2023, with data from 1,162 reported cases, 27,854 exposed people, 19,671 sick 1,443 hospitalized people 31 deaths, resulting a fatality rate 0.16%. analysis highlights importance awareness-raising education actions for population on prevention good food handling practices to reduce incidence these diseases.
Fifteen collaborating laboratories were sent 9 samples of citrus juice mixtures as blind duplicates for determination naringin and neohesperidin by liquid chromatography. Two sample pairs 100% orange did not contain any or neohesperidin. The remaining 7 contained at levels ranging from 3.9 to 46.5 ppm 0.14 35.6 ppm. Five consisted containing 1, 3, 5% grapefruit juice; sour orange; K-Early variety. spiked with naringin, neohesperidin, sodium benzoate, potassium sorbate. Data received 13...
Abstract The Pacific oyster ( Crassostrea gigas ) culture has been expanding, thereby leading to a greater importance of hatcheries. Broodstock conditioning is very important in the hatchery process, which diet composition may have strong influence on offspring production and quality. Therefore, current study evaluated elemental bioaccessibility oysters fed different ratios dietary seaweed (SW) microalgae. consisted direct replacement microalgae by SW at four substitution levels (0%, 25%,...
