TL;DR: Interestingly, the FA distribution of seaweed products showed high levels of n-3FA and demonstrated a nutritionally ideal n-6/n-3 FA ratio.

TL;DR: In this paper, the antioxidant properties of two wild edible mushroom species from the northeast of Portugal, Lactarius deliciosus (L.) Gray and Tricholoma portentosum (Fr.) Quel, were evaluated.

TL;DR: In this article, the authors estimate the amount of total polyphenols consumed in a whole diet (Spanish Mediterranean diet) and their intestinal bioaccessibility and their mean daily intake of polyphenol in the Spanish diet was estimated between 2590 and 3016 mg/person/day.

TL;DR: In this paper, the authors show that the native Cornelian cherry population is an extremely rich source of antioxidants, demonstrating its potential use as a food additive, and demonstrate that the corn variety can be used as food additive.

TL;DR: In this article, the antioxidant capacity and total phenolic content of 23 microalgae were evaluated, using Trolox equivalent antioxidant capacity assay and the Folin-Ciocalteu method, respectively.

TL;DR: The analysis of biogenic amines (BA) in foods was reviewed in this paper, where the analytical methods used for quantification of BA are mainly based on chromatographic methods: thin layer chromatography, gas chromatography (GC), capillary electrophoresis (CE), and high performance liquid chromatography(HPLC).

TL;DR: In this paper, the total antioxidant capacities of 133 Indian medicinal plants sampled from 64 families were assessed by ABTS, DPPH and FRAP assays, and their total phenolic contents measured by Folin-Ciocalteu assay.

TL;DR: In this paper, the formation of volatile compounds and the fruit characteristics that affect the formation are examined in a review of the unique and delicate flavour of olive oil is attributed to the volatile compounds that develop during and after oil extraction from the olive fruit.

TL;DR: In this paper, nine tropical fruits were analyzed for total phenol contents, ascorbic acid contents and antioxidant activities based on the ability of the fruit extracts to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH), reduce iron(III) to iron(II) and to bind to iron (II) ions.

TL;DR: In this article, the oxygen radical absorbance capacity (ORAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and 2, 2′-azinobis(3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) of 19 sweet potato genotypes with distinctive flesh colour (white, cream, yellow, orange and purple) were measured by ORAC.

TL;DR: In this article, the authors examined the free radical scavenging capacity of 26 Thai indigenous plants to determine their potential as a source of natural antioxidants and found that chewing plants which have an astringent taste gave a significantly higher total phenolic content and flavonoid content.

TL;DR: In this paper, the antioxidant properties of three Portuguese wild edible mushroom species, Leucopaxillus giganteus, Sarcodon imbricatus, and Agaricus arvensis, were evaluated.

TL;DR: The results of the study showed that total phenolic content, antioxidant activity, and color parameters differ widely among different honey types as mentioned in this paper, and the relationship between the parameters analysed were found to be statistically significant (p < 0.05).

TL;DR: The results indicated that the tested bacteria were sensitive to the essential oils and partially to the methanolic extracts, and the antimicrobial activities of the essential aromas and extracts differed, depending on location and seasonal variations.

TL;DR: In this article, the antimicrobial and antioxidant activities of the essential oil and methanol extract from Mentha longifolia ssp. l. is evaluated, and the extract showed strong antimicrobial activity against all 30 microorganisms tested whereas the essential oils almost remained inactive.

TL;DR: In this article, fine ground apple pomace was incorporated in wheat flour at 5, 10, and 15% levels and studied for rheological characteristics, including water absorption, resistance to extension, and mixing tolerance index.

TL;DR: The physicochemical, thermal, pasting and gel textural properties of corn starches from different corn varieties (African Tall, Ageti, Early Composite, Girja, Navjot, Parbhat, Partap, Pb Sathi and Vijay) were studied as mentioned in this paper.

TL;DR: In this paper, the antioxidant effect and the total phenols of ginger extract were studied, and the results showed that the ginger extract showed a higher antioxidant activity than quercetin.

TL;DR: In this article, Fibre sources from wheat, rice, oat and barley were used to study their influence on rheological characteristics of wheat flour dough and biscuit making quality.

TL;DR: In this article, the chemical composition of white (Morus alba L), red (Mus rubra L.), and black (Morous nigra L.) mulberry fruits grown in the East Anatolia Region of Turkey was investigated.

TL;DR: In this paper, four different trees (Azadirachta indica, Terminalia arjuna, Acacia nilotica, and Eugenia jambolana Lam) extracts were evaluated for their antioxidant activity, total phenolic (TP), and total flavonoids (TF) contents.

TL;DR: The chestnut flower honey had the highest phenolic content, superoxide radical-scavenging activity and reducing power, while the heterofloral honey sample exhibited the highest peroxynitrite-sc avenging activity.

TL;DR: In this paper, the authors investigated the effects of an in vitro gastric and pancreatic digestion on the stability and composition of the major polyphenols in chokeberry juice, and they showed that a good proportion of these compounds can be transformed into other unknown and/or undetected structural forms with different chemical properties and, consequently, different bioaccessibility, bioavailability and biological activity.

TL;DR: In this paper, the antioxidant properties and total phenolic contents of methanol, acetone and water extracts of mulberry (Morus indica L.) leaves were examined for characterization of antioxidant activity of extracts.
