TL;DR: Guava fruit extracts were analyzed for antioxidant activity measured in methanol extract and dichloromethane extract (AOAD), ascorbic acid, total phenolics, and total carotenoids contents.

TL;DR: A review of the most common and most used spice antioxidants, methods of their preparation and their antioxidant/antiradical properties can be found in this article, where the authors present some information about the most commonly used spices.

TL;DR: In this article, high performance liquid chromatography (HPLC) was employed to analyse non-anthocyanin phenols present in the skins and seeds of 70 grape samples belonging to 10 cultivars.

TL;DR: Bananas contained higher concentrations of lutein than of the provitamin A pigments, α- and β-carotene, and papayas contained 9% of the dietary reference intake (DRI) for Cu, 6–8% ofThe DRI for Mg, but less than 3% for other minerals.

TL;DR: In this paper, the authors have attempted to summarize the kinetic data which can be used to describe the time-temperature effect on nutrients, and have concluded that the most labile vitamins during culinary processes are retinol (vegetable boiling, 33% retention), vitamin C (the most damaging factors are cooking and oxidation), folate (leaching into the cooking water, 40% retention) and thiamin (cooking, retention 20-80%).

TL;DR: In this article, the effects of microwave cooking and other traditional cooking methods such as boiling and autoclaving on the nutritional composition and anti-nutritional factors of chickpeas (Cicer arietinum L.) were studied.

TL;DR: In this paper, byproducts of either winemaking or grape processing were prepared from Vitis vinifera (Merlot and Chardonnay) and Vitis rotundifolia (Muscadine) species.

TL;DR: In this paper, the authors investigated the antioxidant activity (AA) of methanolic extracts from Moringa oleifera leaves, as function of seasons and agroclimatic locations, and observed significant differences in the AA of the extracts from different locations and seasons.

TL;DR: In this article, the effect of three different mineral nutrient solutions (nitrate: ammonium ratios of 4:1 or 1:4), chicken manure and grass-clover mulch on the major carpometric and antioxidant components of greenhouse grown tomatoes was investigated.

TL;DR: It is indicated that germination modifies the quantitative and qualitative phenolic composition of legumes, and the changes depend on the type of legume and the germination conditions, and these changes influence the functional properties of the legumes as consequence of the variation in antioxidant activity.

TL;DR: If, in the future, the nutritional and medical values of the noni can be assessed, especially its anti-cancer activity, this fruit could play a noticeable economic role in producing countries.

TL;DR: Tocopherol and tocotrienol contents of raw fruits and vegetables and processed products were determined by saponification and normal phase liquid chromatography as mentioned in this paper, and the results showed that α-tocopherol (α-T) was detectable in all products and usually represented the vitamin E form present in highest quantity.

TL;DR: The Food and Agriculture Organization of the United Nations (FAO) and the International Plant Genetic Resources Institute (IPGRI) are leading a new international initiative on biodiversity for food and nutrition under the umbrella of the Convention of Biological Diversity.

TL;DR: In this paper, a high-performance liquid chromatography-diode array detection (DAD) procedure was used for determination of phenolic acids content in dry beans ( Phaseolus vulgaris L.).

TL;DR: The database provides information on several varieties of citrus and eight flavanone compounds, including hesperidin and narirutin, which constitute the majority of flavonoids in citrus fruits such as sweet and sour oranges and their near relatives—tangerines/mandarins and tangelos.

TL;DR: In this article, the authors developed a database for flavanones, the dominant flavonoid class in the genus citrus, and relevant scientific literature on flavonoids in grapefruit, lemons and limes was searched, abstracted, documented, standardized by taxons and units (mg/100 g).

TL;DR: In this paper, two tomato cultivars were grown in two high tunnels at Beltsville, MD covered with a contrasting material of similar thickness (0.152mm) and durability (4-year polyethylene).

TL;DR: In this paper, the compositional profile of greenhouse cherry tomatoes harvested at six different times of the year was compared to evaluate seasonal variations in antioxidant components of greenhouse tomatoes, and the authors found that tomatoes harvested in mid-summer were characterized by lowered lycopene levels.

TL;DR: An updated review on the analysis of carotenoids in vegetable, plasma and serum samples is presented in this paper, where general aspects of chromatographic analysis are commented on, and examples of separation in different samples are shown.

TL;DR: In this article, the effects of heating time and pH values on the commonly used lithium hydroxide/acetic acid buffer system were investigated, and the suitability of using sodium hydroxideside/acetate buffer to replace the traditional LHA buffer was also evaluated.

TL;DR: In this article, the fatty acid composition of 25 pomegranates varieties obtained from two different regions of Iran (Punica granatum L.) was qualitatively and quantitatively determined by gas chromatography.

TL;DR: In this article, the authors studied the antioxidant properties of three commercial New Zealand tomato cultivars, Excell, Tradiro, and Flavourine, in a greenhouse over a period of 8 months.

TL;DR: The USDA Survey Nutrient Database and other technical files used to code foods and calculate nutrient values for national food consumption surveys were updated, redesigned, and renamed the USDA Food and Nutrients Database for Dietary Studies (FNDDS).

TL;DR: In this paper, the antioxidant activity of free and bound phenolics of amla (Emblica officinalis) and turmeric (Curcuma longa) was investigated.

TL;DR: In this paper, the retention of β-carotene in boiled, mashed orange-fleshed sweet potato (OFSP), variety Resisto, was evaluated using a high-performance liquid chromatographic method.

TL;DR: In this article, the composition of ethanolic extracts of peanut skin obtained from each processing method was determined by LC-MS and HPLC, which significantly affected total extractable phenolics and their composition.

TL;DR: In this article, the authors provide an up-to-date compilation of data on the flavonol composition of grapes and some of the principal commodities deriving from them, including grape juices and wines.

TL;DR: It appears that there is no imminent health risk due to heavy metals examined in this study for the total diet of the Korean population.

TL;DR: In this paper, the vitamin C (ascorbic acid) and mineral content of six cultivars of Dimocarpus longan, Lychee (Litchi chinensis ), and rambutan ( Nephelium lappaceum ) were analyzed from different locations in Hawaii.

TL;DR: Eggplant extracts from the AVRDC Solanum collection have demonstrated potency in scavenging reactive oxygen species that are implicated in many human diseases and sufficient genetic diversity exists in S. melongena for SOS and total phenolics to justify evaluation of a larger number of accessions.
