Five Korean blueberries (’’Nelson’’, ’’Duke ’’, ’’Bluejay ’’, ’’Toro’’, and ’’Elliot ’’) were harvested at two maturity stages (unripe and ripe) to evaluate fruit quality and antioxidant activities. The Hunter L, a, and b color of ripe blueberries was lower than that of unripe fruit. Soluble solid concentration (SSC) and pH increased, and titratable acidity (TA) and firmness decreased as the blueberries matured. The ripe blueberry fruits showed a higher SSC/TA ratio than the unripe fruits. Although total anthocyanin, flavonoids, phenolics content, and antioxidant activity were higher in ripe blueberries than in unripe fruit, the unripe fruit had higher acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibition activities than ripe fruit in all cultivars. Total antioxidant activity was highly correlated with total flavonoids and phenolics. The relationships between the total antioxidant activity and the AChE or BChE inhibitory activity are negative. There were several physicochemical quality and antioxidant activity differences in blueberries, depending on the cultivar and the maturity at harvest. Unripe fruits also contain potential health-promoting bioactive compounds as functional food ingredients.

“…Both RCH and RSP presented similar (p < 0.05) aw levels within the range typically found for stable spraydried powders [33], besides displaying attractive, vibrant green colors (Figure 2). The spray dried algae-rosemary particles were also characterized regarding the concentration of rosemary phenolic diterpenes, carnosic acid (CA), carnosol (CR), and rosmarinic acid, recognized as potent antioxidant molecules with superior performance when compared to synthetic antioxidants used in the industry [9] and several biological activities [14]. Our results (Figure 3) show that RSP particles captured significantly higher concentrations of rosemary antioxidants when compared to RCH particles.…”

“…A common pathway to identify promising sources of active phytochemicals involves the search for plant species traditionally used in folk or traditional medicine. For example, rosemary (Rosmarinus officinalis) is an aromatic plant that has long been used in herbal remedies due to its multiple biological activities including antioxidant, antimicrobial, antiinflammatory [9][10][11] and skin renewal properties [12]. It is recognized as a major source of bioactives, mainly phenolic compounds such as rosmarinic acid, carnosic acid, and carnosol [13] and has attracted interest from food, pharmaceutical, and health-related industries worldwide [10,14].…”

Novel Spray Dried Algae-Rosemary Particles Attenuate Pollution-Induced Skin Damage

et al. 2021

The present study investigated the effect of spray-dried algae-rosemary particles against pollution-induced damage using ex-vivo human biopsies exposed to diesel engine exhaust (DEE). For this, the complexation of hydroalcoholic rosemary extract with Chlorella (RCH) and Spirulina (RSP) protein powders was conducted. The process efficiency and concentration of rosmarinic acid (RA), carnosic acid (CA), and carnosol (CR) phenolic compounds of both products were compared. The RSP spray-dried production was more efficient, and RSP particles presented higher CR and CA and similar RA concentrations. Therefore, spray-dried RSP particles were prioritized for the preparation of a gel formulation that was investigated for its ability to mitigate pollution-induced skin oxinflammatory responses. Taken altogether, our ex-vivo data clearly demonstrated the ability of RSP gel to prevent an oxinflammatory phenomenon in cutaneous tissue by decreasing the levels of 4-hydroxynonenal protein adducts (4HNE-PA) and active matrix metalloproteinase-9 (MMP-9) as well as by limiting the loss of filaggrin induced by DEE exposure. Our results suggest that the topical application of spirulina-rosemary gel is a good approach to prevent pollution-induced skin aging/damage.

“…These uses are based on the ability of active rosemary components or other natural extracts to block harmful processes fed by the diffusion of oxygen. The main component of antioxidant blends in rosemary extract—carnosic acid, a polyphenol [ 10 , 11 ]—has a large abundancy in different extracts. The summary of contributions brought about by the significant components of rosemary powders on the overall stabilization effect indicates these compounds as the efficient stimulants for the protection against oxidation [ 12 ].…”

In this work the analysis on the stabilization activities of some natural antioxidants (rosemary extract, capsaicin, quercetin or oleanolic acid) is presented. A similar contribution of an inorganic structure—polyhedral oligomeric silsesquioxane (POSS) nanoparticles—is also evaluated. The stabilization effects on the oxidation protection were investigated for several formulations based on ethylene-propylene-diene-terpolymer (EPDM). The samples were examined in pristine state or after γ-irradiation, when the accelerated degradation scission of polymer macromolecules followed by the mitigation of oxidation. Three evaluation procedures: chemiluminescence, FTIR spectroscopy and thermal analysis were applied for the characterization of stability efficiency. The delaying effect of oxidative aging in EPDM matrix is illustrated by the values of activation energy, which are correlated with the type and concentration of embedded compounds. The durability of studied EPDM formulations is discussed for the assessment of material life. The improved behavior of structured hybrids useful for the optimization application regimes is essentially based on the antioxidant properties of polyphenolic components in the cases of natural antioxidants or on the penetration of free radical intermediates into the free volumes of POSS.
