TL;DR: Goji berry was identified as a rich source of antioxidant compounds, with health-promoting properties comparable with other common fruit species, and may be useful to better understand the nutraceutical traits of this species recently considered as functional food.

TL;DR: In this paper, the effect of food matrix (water-, milk-, or soymilk-fruit juice beverages) and processing [high intensity pulsed electric fields (HIPEF); high pressure processing (HPP); and thermal treatment (TT)] on the in vitro bioaccessibility of vitamin C and phenolic compounds, as well as on the hydrophilic antioxidant activity (HAA) of fruit juice-based beverages was analysed.

TL;DR: Universal guidelines for the evaluation of BAPs in humans such as adequately powered double-blind randomised clinical trials are needed.

TL;DR: The purpose of this review is to discuss the effects of CLA on health and disease and the possible mechanisms for CLA activities.

TL;DR: This meta-analysis showed a significant effect of curcuminoids in elevating serum SOD and catalase activities, GSH concentrations, and reduction of serum lipid peroxides.

TL;DR: Elderberry is a good source of protein, free and conjugated forms of amino acids, unsaturated fatty acids, fibre fractions, vitamins, antioxidants and minerals.

TL;DR: In this paper, the bioactive compounds and chemical composition of jabuticaba and jussara fractions were determined in each fruit, of which soluble forms were predominant, anthocyanins being the most abundant phenolics.

TL;DR: The finding indicated that Trp-Pro-Pro could be used to eliminate the excessive ROS produced under oxidative stress conditions and prevent cancers caused by a large number of free radicals.

TL;DR: This mini-review collects and discusses the scattered data available in the literature concerning oleuropein and/or ole Kuropein-rich extracts and highlights its chemistry, biosynthesis, biological activities and its possible mechanisms of action.

TL;DR: The concept of oxidative stress, the factors responsible for oxidative stress and on those substances in foods that may have in vivo effects in terms of decreasing the adverse effects of reactive oxygen species and reactive nitrogen species on normal physiological function are reviewed.

TL;DR: In this article, the authors compared polyphenolic profile and antioxidant activity in leaves and fruits of 7 selected species: Malus domestica (2 cultivars), Cydonia oblonga (4 cv), Chaenomeles japonica (3 cv.), Ribes nigrum (3cv), Aronia melanocarpa (1 cv).

TL;DR: In this paper, date seed flour was used to produce protein hydrolysates using Alcalase (AL), Flavourzyme (FL) and Thermolysin (TH).

TL;DR: The influence of lipid droplet size of excipient emulsions on the solubility and bioaccessibility of powdered curcumin was investigated in this article, where corn oil-in-water emulsion with different initial mean droplet diameters were prepared.

TL;DR: Omega-3 fatty acids and probiotic bacteria were co-encapsulated in a single whey protein isolate (WPI)-gum Arabic (GA) complex coacervate microcapsule and the oxidative stability of tuna oil was significantly higher in spray dried co-capsules than in freeze dried ones.

TL;DR: In this article, the authors evaluated the antioxidant properties of 23 edible flowers, including Osmanthus fragrans (Thunb), Paeonia lactiflora Pall, and Rosa rugosa Thunb, and found that these flowers are important natural sources for the prevention of oxidative stress diseases.

TL;DR: In this paper, the stability of pomegranate phenols during digestion was tested by the application of in vitro gastrointestinal digestion (GID) to different products: juice, pulp, and peel extract (PE).

TL;DR: In this article, the antioxidant capacity of fermented soy whey (FSW) was investigated in order to find out their nutraceutical potential, and unfermented USW was used as a control, and the results suggested that FSW with enhanced antioxidant capacity could provide a functional soy beverage to contribute to the health and nutritional status improvement of consumers.

TL;DR: In this paper, free, esterified, and insoluble-bound phenolics were extracted from selected lentil cultivars and total phenolics, flavonoids and proanthocyanidin contents were determined.

TL;DR: A higher free EA intake does not enhance its bioavailability but promotes urolithin production, and Bioavailability of EA, as the unchanged fraction that reaches the systemic circulation, is not as low as previously thought.

TL;DR: In this paper, the effect of in vitro gastrointestinal digestion (GID) on the recovery, bioaccessibility and stability of polyphenolic compounds, the changes in antioxidant activity and the short chain fatty acids (SCFAs) production of pomegranate peel flour (PPF) were evaluated.

TL;DR: Results indicated that the novel peptides isolated from grass carp skin possess potent antioxidant activities and might be used for food preservation and medicinal purposes, however, more detailed studies are required to explore their antioxidant abilities in vivo.

TL;DR: In this article, the physicochemical characteristics and acceptance of Lactobacilli-fermented cereal beverages individually inoculated with human derived Lactibacillus acidophilus NCIMB 8821, Lactebacillus plantarum NCIMBP 8826, and Lactabacillus reuteri NCIMP 11951 were evaluated after 10 h of incubation at 37 °C.

TL;DR: Wang et al. as discussed by the authors evaluated three red-fleshed varieties from Xinjiang, P.R. China and one from the USA and found that Roberts Crab had the highest amounts of total phenolics, flavonoids, and anthocyanins, as well as the strongest antioxidant activity.

TL;DR: The phenolic content of white and black mulberry fruits with proven market aptitudes and grown in Spain, one of the main European producers, showed higher antioxidant activity and amounts of phenolic compounds than white mulberry clones, although a wide intra-species variability was noted.
