As a secondary starter, this can be incorporated to boost the probiotic content of fermented milk products.
An underutilized edible oil seed, the African oil bean (Pentaclethra macrophylla Benth), has the potential to serve as a sustainable source of protein. To determine the impact of sonication, this study evaluated the efficiency of protein extraction and protein properties from African oil bean (AOB) seeds. The longer the extraction time, the more efficient the extraction of AOB proteins became. The extraction procedure's duration, expanded from 15 minutes to 60 minutes, led to an elevation in extraction yield, increasing from 24% to 42% (w/w). Observed properties of the extracted AOB proteins were favorable; the amino acid makeup of the isolated proteins revealed a higher hydrophobic-to-hydrophilic amino acid ratio compared to that of the defatted seeds, suggesting a shift in their functional performance. AOB protein isolates exhibited a greater abundance of hydrophobic amino acids and a substantial surface hydrophobicity index value (3813), thus bolstering this finding. The foaming ability of AOB proteins exceeded 200%, exhibiting an average foam stability of 92%. Analysis reveals that AOB protein isolates demonstrate potential as food ingredients, a development that could stimulate the tropical Sub-Saharan food industry, given the prevalence of AOB seed cultivation in these areas.
An expanding market for shea butter is evident in its growing use in food, cosmetics, and pharmaceutical products. An examination of how the refining process impacts the quality and stability of fractionated and blended shea butters is the focus of this work. Crude shea butter, refined shea stearin, olein, and their combined mixture (11% w/w) were analyzed with respect to fatty acids, triacylglycerol composition, peroxide value, free fatty acids, phenolic and flavonoid content, unsaponifiable matter, tocopherol content, and phytosterol content. The oxidative stability, free radical scavenging activity, effectiveness against bacteria, and effectiveness against fungi were all investigated. From the shea butter samples, stearic acid and oleic acid emerged as the two primary fatty acid constituents. The refined shea stearin's composition indicated lower values for PV, FFA, USM, TPC, TFC, RSA, tocopherol, and sterol when contrasted with the crude shea butter. The EC50 value was observed to be higher, however, the antibacterial activity was demonstrably lower. While the refined olein fraction showed lower levels of PV, FFA, and TFC than crude shea butter, its USM, TPC, RSA, EC50, tocopherol, and sterol content remained constant. An elevated antibacterial activity was seen, however, antifungal activity remained lower than that of crude shea butter. zinc bioavailability The mixed versions of both fractions shared analogous fatty acid and triacylglycerol compositions with crude shea butter, but other metrics presented contrasting results.
The popular food ingredient, Chlorella vulgaris microalgae, is extensively utilized in the industry, witnessing a surge in market size and value. Several commercially available C. vulgaris edible varieties are currently marketed, with distinct organoleptic characteristics aimed at consumer appeal. This study sought to analyze the fatty acid (FA) and lipid profiles of four commercially available strains of Chlorella vulgaris (C-Auto, C-Hetero, C-Honey, and C-White) employing gas- and liquid-chromatography coupled with mass spectrometry, in addition to investigating their antioxidant and anti-inflammatory capacities. The findings highlight that the C-Auto strain displayed a higher lipid composition in comparison to other strains, and significantly higher concentrations of omega-3 polyunsaturated fatty acids (PUFAs). While the other strains presented lower levels, the C-Hetero, C-Honey, and C-White strains contained a greater abundance of omega-6 PUFAs. Between the strains, significant lipidome differences were observed, with C-Auto having an enriched level of polar lipids linked to omega-3 PUFAs, in contrast to C-White's richer composition of phospholipids incorporating omega-6 PUFAs. Triacylglycerols were more abundant in C-Hetero and C-Honey samples. Antioxidant and anti-inflammatory activity was displayed by every extract, with C-Auto exhibiting the most promising potential. From a broader perspective, the four strains of *C. vulgaris* are ideal for selective harvesting of valuable lipids, effectively usable in food and nutraceutical sectors, adapting to various consumer needs and nutritional prerequisites.
Employing Saccharomyces cerevisiae and recombinant Pediococcus acidilactici BD16 (alaD+), a two-stage fermentation process was used to produce fermented wheatgrass juice. In the course of wheatgrass juice fermentation, a reddish-brown tint emerged, stemming from the generation of diverse red pigments. The fermented wheatgrass juice surpasses unfermented wheatgrass juice in terms of anthocyanins, total phenols, and beta-carotenes content, showing a considerable elevation. Wheatgrass juice exhibits low ethanol levels, a characteristic possibly related to the presence of particular phytolignans. Using liquid chromatography (LC)-mass spectrometry (MS)-matrix-assisted laser desorption/ionization (MALDI)-time-of-flight (TOF)/time-of-flight (TOF) analysis, a wide array of yeast-mediated phenolic transformations were identified in fermented wheatgrass juice. These included the bioconversion of coumaric acid, hydroxybenzoic acid, hydroxycinnamic acid, and quinic acid, along with glycosylation and prenylation of flavonoids, glycosylation of lignans, sulphonation of phenols, and the synthesis of carotenoids, diarylnonanoids, flavanones, stilbenes, steroids, quinolones, di- and tri-terpenoids, and tannins. Recombinant Pediococcus acidilactici BD16 (alaD+) showcased an ability to support not only flavonoid and lignin glycosylation, but also the derivation of benzoic, hydroxycoumaric, and quinic acids, along with the biosynthesis of potentially therapeutic anthraquinones, sterols, and triterpenes. The manuscript's presentation of the information regarding Saccharomyces cerevisiae and P. acidilactici BD16 (alaD+) mediated phenolic biotransformations clarifies their importance in the creation of functional food supplements, including fermented wheatgrass juice.
Nanotechniques for curcumin (Cur) encapsulation hold the potential to overcome limitations and improve the biological effects of curcumin in food and pharmaceutical formulations. This study explored a novel one-step coaxial electrospinning process to self-assemble zein-curcumin (Z-Cur) core-shell nanoparticles within Eudragit S100 (ES100) fibers, contrasting with multi-step encapsulation methods. The encapsulation efficiency (EE) for ES100-zein-Cur (ES100-Z-Cur) reached 96%, while the EE for independently self-assembled Z-Cur nanoparticles incorporating curcumin (Cur) was 67%. The structure that resulted exhibited a dual protective layer, thanks to ES100 and zein, ensuring both pH-responsive and sustained release characteristics for Cur. check details Upon release from the fibermats, the Z-Cur nanoparticles displayed a spherical structure (diameter 328 nm) and a relatively uniform distribution, as indicated by a polydispersity index of 0.62. Using transmission electron microscopy (TEM), the spherical structures of Z-Cur nanoparticles and Z-Cur nanoparticles embedded in ES100 fibermats were visualized. FTIR and XRD measurements indicated that hydrophobic interactions were observed between the encapsulated curcumin (Cur) and zein, with the curcumin remaining amorphous rather than crystallizing. HIV – human immunodeficiency virus The incorporation of fibermat into the system could substantially improve the photothermal resilience of Cur. This innovative one-pot approach remarkably and effectively integrated nanoparticles and fibers, yielding advantages such as streamlined procedures, ease of operation, and improved synthetic outcomes. Sustainable and controllable intestine-targeted drug delivery is possible with Cur-infused core-shell biopolymer fibermats used in pharmaceutical products.
