SP had low total phenolic content (7.

Sonoprocessing enhances the stabilization of fisetin by encapsulation in Saccharomyces cerevisiae cells.

The objective of this study was to investigate for the first time the role of S. cerevisiae natural barriers and endogenous cytoplasmatic bodies on the stabilization of fisetin encapsulated via sonoprocessing coupled to freeze-drying (FD) or spray drying (SD). Both protocols of encapsulation improved the resistance of fisetin against thermal treatments (between 60 and 150 °C) and photochemical-induced deterioration (light exposition for 60 days) compared to non-encapsulated fisetin (antioxidant activity retention of approximately 55% and 90%, respectively).

Effect of Microwave and Ultrasound-Assisted Extraction on the Phytochemical and In Vitro Biological Properties of Willow ( Bark Aqueous and Ethanolic Extracts.

White willow () is a medicinal plant used in folk medicine. In this study, aqueous and ethanolic willow bark extracts were obtained via ultrasonic-assisted extraction (UAE) and microwave-assisted extraction (MAE), and analyzed regarding their phytochemical (total phenolics, phenolic acids, flavonoids, and tannins) content and in vitro biological properties (antibacterial and antifungal activity, acetylcholinesterase AChE inhibitory activity and anti-inflammatory effects). The highest phenolic, tannin, and flavonoid contents were found for willow bark extracts obtained via microwave-assisted extraction using ethanol as a solvent (SA-ME).

Spray-drying microencapsulation of blackcurrant and cocoa polyphenols using underexplored plant-based protein sources.

The performance of buckwheat protein (BK) and chia seed protein (CP) as drying carriers for the microencapsulation of polyphenols extracted from blackcurrant pomace and cocoa powder was investigated. Four experimental groups were evaluated (BK-BC: blackcurrant pomace extract with buckwheat protein; CP-BC: blackcurrant pomace extract with chia:pea protein blend; BK-CC: cocoa extract with buckwheat protein; and CP-CC: cocoa extract with chia:pea protein blend) to determine physicochemical attributes, phytochemical content, antioxidant activity, and polyphenol in vitro bioaccessibility. Nonconventional, underexploited protein sources such as chia/pea protein blend and buckwheat protein efficiently produced functional microparticles with attractive color and texture, low hygroscopicity (<20% increase in moisture content when exposed to 86% relative humidity for 1 week), solubility above 50% at pH 7 and 10, and uniform particle size (29 < D  < 56 µm).

Total Utilization-Upcycling of Mushroom Protein By-Product: Characterization and Assessment as an Alternative Batter Ingredient for Fried Shrimp.

Mushroom by-products are economical and eco-friendly raw materials with bioactive and functional characteristics that allow for potential uses as food ingredients. However, mushroom upcycling has yet to be fully exploited, despite the many opportunities that mushrooms may offer. The mushroom protein by-product (MPBP) resulting from mushroom protein production was characterized (chemical composition, physicochemical attributes, and functional properties) and incorporated into plant-based batter formulations to prepare four experimental groups with different ratios (, %) of wheat flour (W) to MPBP (100 W, 75 W/25 MPBP, 25 W/75 MPBP, and 100 MPBP).

Novel Liquor-Based Hot Sauce: Physicochemical Attributes, Volatile Compounds, Sensory Evaluation, Consumer Perception, Emotions, and Purchase Intent.

Hot sauces are popular peppery condiments used to add flavor and sensory excitement to gastronomical preparations. While hot sauce occupies a retail category well over a century old, a novel production method using liquor as the base preservative rather than traditional vinegar is now commercially available, and its uniqueness begs study. Hot sauces produced with tequila, rum, vodka, and bourbon were compared to traditional vinegar-based hot sauces concerning physicochemical properties, volatile compounds, microbiological quality, sensory scores, emotions, and purchase intent (PI).

Sonoprocessing is an effective strategy to encapsulate fisetin into Saccharomyces cerevisiae cells.

The encapsulation of fisetin into S. cerevisiae cells through sonoporation coupled with drying is reported for the first time in the literature. To establish the best conditions to maximize the amount of internalized fisetin, the cell density (5-10% w/v), fisetin concentration (1-3 mg/mL), acoustic energy density (0-333.

Boosting the Bioaccessibility of Dietary Bioactives by Delivery as Protein-Polyphenol Aggregate Particles.

Protein-polyphenol aggregate particles concurrently fortify a functional food product with healthy dietary proteins and concentrated polyphenols. However, what impact does ingestion of aggregate particles have on ultimate health relevance of either the polyphenolic molecules in the matrix or the protein molecules? Because human health benefits are contingent on bioavailability after ingestion, the fate of these molecules during transit in the gastrointestinal tract (GIT) will dictate their utility as functional food ingredients. This brief review explores diverse applications of protein-polyphenol particles in the food industry and the bioaccessibility of both bioactive polyphenolic compounds and edible proteins.

Foaming characteristics and impact of ethanol pretreatment in drying behavior and physical characteristics for avocado pulp powder obtained by foam mat drying.

The best results were achieved when 15 MPa was applied, while the maximum loading capacity was reached when fisetin concentration of 2.

Efficient stabilisation of curcumin microencapsulated into yeast cells via osmoporation.

This study proposes the investigation of curcumin encapsulation into Saccharomyces cerevisiae cells through osmoporation as an efficient way of increasing curcumin stability. The influence of three process parameters (cell, ethanol and curcumin concentrations) on the encapsulation process was evaluated, and the obtained biocapsules were characterised for physical and photochemical stabilisation. Results showed that encapsulation efficiency was favoured by the increase of cells/curcumin ratio and ethanol concentration up to 60%.

Comparison of berry juice concentrates and pomaces and alternative plant proteins to produce spray dried protein-polyphenol food ingredients.

Spray dried functional food ingredients were prepared by complexing alternative plant protein sources - buckwheat flour alone or blended with pea and rice proteins, with polyphenol sources - blueberry, cranberry and purple muscadine grape extracts from juice concentrates and pomaces - to create colloidal aggregate powders. When fruit pomaces (rather than juice concentrates) were used as polyphenol resources, solid recovery was significantly enhanced, especially for matrices made with pea protein, buckwheat flour or pea-buckwheat blends (over two fold for pea protein-berry pomace aggregates). Polyphenol content and DPPH radical scavenging capacity were, in general, significantly greater for pomace-derived protein-polyphenol aggregates compared to those made with juice concentrates.

Blueberry polyphenol-protein food ingredients: The impact of spray drying on the in vitro antioxidant activity, anti-inflammatory markers, glucose metabolism and fibroblast migration.

Wild blueberry pomace extract complexed with wheat or chickpea flour or soy protein isolate produced spray dried and freeze-dried polyphenol-protein particles. To evaluate the impact of spray drying on the biological activity of these food ingredients in vitro antioxidant and anti-inflammatory activities, regulation of glucose metabolism and ability to stimulate fibroblast migration were tested. Extracts from polyphenol-protein particles significantly decreased reactive oxygen species (ROS) production and down-regulated the gene expression of inflammation markers (COX-2 and IL-1β).
