Acute effects of intra-training carbohydrate ingestion in CrossFit® trained adults: a randomized, triple-blind, placebo-controlled crossover trial.

Carbohydrate (CHO) intake during exercise could decrease the subjective perceived exertion and promote recovery; however, the effects of intra-training CHO ingestion remain uncertain in CrossFit® (CF) sessions. Therefore, the aim of this randomized, triple-blind, placebo-controlled crossover trial was to investigate the effect of acute CHO intake during a CF session on the delayed onset muscle soreness (DOMS), the perceived exertion (RPE), performance, recovery, and metabolic markers (capillary lactate and glucose) in CF athletes. Twenty-three male athletes trained in CF ingested CHO (60 g of maltodextrin + fructose) or a placebo (PLA) during a CF session.

The chemical composition of barley grain (Hordeum vulgare L.) landraces from the Canary Islands.

The proximate composition, total phenolics, antioxidant activity, minerals, and trace elements were determined in 42 barley landraces in order to highlight their nutritional potential and promote their cultivation. Two-row barley landraces had a higher average content of starch, protein, total phenolic compounds, and iron, when compared with six-row ones that presented higher mean ash and fiber concentrations. Additionally, the six-row barley landraces with strongly pigmented grains had lower zinc and manganese and higher protein mean concentrations than the whitish or lightly pigmented barley landraces.

Physicochemical characteristics and pollen spectrum of monofloral honeys from Tenerife, Spain.

Physicochemical parameters, sugar composition and botanical origin were determined in four monofloral honeys, chestnut, fennel, tajinaste, and Teide broom honeys, abundantly produced in Tenerife Island. All the parameters were within the established intervals in Europe for each type of honey. Large differences between the four monofloral honeys were observed, being the chestnut honeys with most of differential characteristics.

The Compositional HJ-Biplot-A New Approach to Identifying the Links among Bioactive Compounds of Tomatoes.

Tomatoes have been described as a functional food because of their particular composition of different bioactive compounds. In this study, the proximate composition, minerals and trace elements, and antioxidant compounds were determined in two tomato cultivars (Mariana and Dunkan) that were grown in Gran Canaria (Spain) either conventionally or hydroponically. Although compositional data of this type require being subjected to the specific statistical techniques of compositional analysis, this approach has not usually been considered in this context.

What Gives a Wine Its Strong Red Color? Main Correlations Affecting Copigmentation.

Copigmentation and enological parameters were studied in a collection of 250 red wines. Although several copigmentation studies have been performed with model solutions, little is known about the actual consequences directly in wine of anthocyanin interactions. To date, some studies have considered relationships between copigmentation and natural wine constituents, but none correlates copigmentation measurements with the real wide concentration in wine.

Physicochemical characterization of cactus pads from Opuntia dillenii and Opuntia ficus indica.

The physicochemical characteristics of both species were clearly different. There were important differences between the orange and green fruit pulp of O.

Influence of diet and rennet on the composition of goats' milk and cheese.

Dry matter, protein, fat, pH, mineral (Na, K, Ca and Mg) and trace elements (Fe, Cu, Zn and Se) concentrations were determined in samples of goats' milk and in fresh, semi-hard and hard cheeses to study the effect of the goats' diet and the type of rennet used for the cheese processing of the Palmero Protected Designation of Origin cheeses. Two groups of 20 Palmero goats were fed 2 different diets: a Palmero diet (PD supplied by native forages adapted to subhumid areas, which had a high ratio of long fibre to concentrates (65:35), and an actual diet (AD), the most commonly used by goat farmers, with a low ratio of long fibre to concentrates (35:65). In general, the cheese samples from goats fed with PD had higher mean Ca, Zn, Cu and Se concentrations than the samples obtained from AD fed goats.

Cluster analysis and artificial neural networks multivariate classification of onion varieties.

Eight cultivars of different colored onions (white, golden, and red) were evaluated for fresh bulbs cultivated and grown under the same environmental and agronomical conditions. Cluster analysis and principal component analysis, based on different flavonoids, total phenols, and pungency, data showed that the onions were not clustered according to variety (genetic similarity degree), whereas the color was the variable with the highest influence, ranging between 50 and 70%. Artificial neural networks were applied to study the possibility of discriminating among onion varieties.

Influence of the cultivar on the organic acid and sugar composition of potatoes.

Background: Citric, malic, tartaric, oxalic, ascorbic, aconitic and fumaric acids, and sucrose, fructose and glucose, were determined in ten potato cultivars (Azucena negra, Bonita, Bonita negra, Borralla, Colorada de baga, Mora, Negra, Palmera lagarteada, Peluca blanca and Terrenta) from the Canary Islands in order to differentiate them. The influence of the production zone was also considered.

Results: Citric acid and sucrose were the most abundant organic acid and sugar, respectively.

Aloe vera as a functional ingredient in foods.

The main scientific discoveries on Aloe vera published mainly in the last three decades are presented in this work. After describing Aloe from a botanical point of view, the papers related with the chemical composition of different parts of the leaf of Aloe, particularly those in which the gel is described and are presented in a synthetic manner. The chemical analyses reveal that Aloe gel contains mannose polymers with some glucose and other sugars, among which the most important is Acemannan.

Comparison of the mineral and trace element concentrations between 'gazpacho' and the vegetables used in its elaboration.

Contents of moisture, ash and minerals and trace elements (sodium, potassium, calcium, magnesium, iron, copper, zinc and manganese) were determined in vegetable samples--garlic, tomato, white onion, cucumber, pepper--in 'gazpacho', which was elaborated using these vegetables. The mean sodium concentration in 'gazpacho' was much higher than those mean values observed in the fresh vegetables. The mean values of the minerals studied in the 'gazpacho', except sodium and calcium, tend to be lower than the mean values in the vegetables used.

Organic acid contents in onion cultivars (Allium cepa L.).
