Traditional use of noncultivated vegetables has decreased with the development of agriculture and global supply chains. However, some species are still consumed as part of our traditional Mediterranean diet. Plants are among the most important sources of natural antioxidants for retarding lipid oxidative rancidity in foods or for pharmaceutical applications(More)
BACKGROUND No comprehensive reports exist on the combined effects of season, cultivation environment and genotype on eggplant (Solanum melongena) composition. We studied proximate composition, carbohydrates, total phenolics and vitamin C of eggplant fruits of three Spanish landraces, three commercial hybrids and three hybrids between landraces cultivated(More)
With the purpose of estimating the lycopene concentration in tomato food samples, in an non-destructive way, several types of linear models of color parameters have been tested using individual values of L*, a* and b* values, (a*/b*), (a*(2)/b*(2)) and chroma parameters from tomato juice and fresh tomato fruits obtained with two different apparatus (Minolta(More)
Tomato quality and its potential health benefits are directly related to its chemical composition. The characterization of nutritional properties of Solanum germplasm is essential to choose suitable donor parents for breeding programs. In this sense, wild species could be very useful for tomato fruit quality genetic improvement. With this objective, in this(More)
Polyunsaturated fatty acids play an important role in human nutrition, being associated with several health benefits. The analyzed vegetables, in spite of its low fat content, lower than 2%, present a high proportion of polyunsaturated fatty acids of n-3, n-6 and n-9 series, such as α-linolenic, linoleic and oleic acids, respectively. Wild edible plants(More)
In this study a new computerized approach and linear models (LMs) to solve the UV/vis spectroscopy interference effects of beta-carotene with lycopene analysis by neural networks (NNs) are considered. The data collected (absorbance values) obtained by UV/vis spectrophotometry were transferred into an NN-trained computer for modeling and prediction of(More)
We developed a novel computerized approach based on lag-k autocorrelation coefficients (LCCs) and linear models (LMs) to estimate the concentration of lycopene in foods by the spectroscopy. The LCCs were calculated using the data obtained using whole visible scans from 400 to 600 nm (vide supra) of lycopene standards and food samples (ketchup, tomato juice(More)
Wild Fragaria vesca L. fruits were studied regarding nutritional and phytochemical compounds, and also antioxidant, antibacterial and biofilm formation inhibition activities. The fruits are good sources of carbohydrates (e.g., sucrose), soluble dietary fiber and polyunsaturated fatty acids, mainly linoleic and linolenic acids, as well as other components(More)
BACKGROUND It is known that insufficient consumption of fiber in Western societies is directly linked to certain diseases. The required daily fiber intake can be obtained from foods such as fruits and vegetables, whole grains, legumes, nuts and others, or by eating foods enriched with fiber as a functional ingredient. OBJECTIVE This review studies certain(More)
BACKGROUND Wild vegetables have traditionally been consumed as part of the Mediterranean diet, being valuable sources of nutrients and bioactive compounds. The objective of this work was to analyse the carotenoid content of the edible young shoots of four species (Asparagus acutifolius L., Humulus lupulus L., Bryonia dioica Jacq. and Tamus communis L.) as(More)
