A single dose of purple grape juice improves physical performance and antioxidant activity in runners: a randomized, crossover, double?blind, placebo study.

PurposeTo investigate the effects of a single dose of juice on physical performance, oxidative stress, inflammation and muscle damage in runners.Methods Fourteen recreational male runners (39 ± 9 years, VO2peak = 55.9 ± 6.5 ml/kg/min) performed two running tests to exhaustion at 80% of VO2max after ingesting grape juice or a placebo drink (10 ml/kg/day) randomly. Blood samples were taken before and 2 h after supplementation and immediately after running to analyze total antioxidant capacity (TAC), malondialdehyde (MDA), alpha-1 acid glycoprotein (A1GPA), high-sensitivity C-reactive protein (hs-CRP), creatine kinase (CK) and lactate dehydrogenase (LDH).ResultsThe participants ran for an average of 59.2 ± 27.8 min until exhaustion in the placebo group and for 68.4 ± 29.7 min until exhaustion in the grape juice intake group, which was a significantly longer time (p = 0.008). This improvement in physical performance was accompanied by a 43.6% increase in TAC (p = 0.000) at the post-exercise timepoint compared to the level at baseline. MDA, A1GPA, hs-CRP, CK, and LDH did not exhibit changes. In contrast, no significant change in any variable was observed after consuming the placebo drink.ConclusionThe single-dose intake of purple grape juice demonstrated an ergogenic effect in recreational runners by increas-ing run time to exhaustion and increasing antioxidant activity

Effect of the inoculum/substrate ratio on the biochemical methane potential (BMP) of grape marc.

The grape industrialization process produces large volumes of solid organic waste, with the grape bagasse being the main waste generated in the winemaking process. Anaerobic digestion can be used to treat and dispose of agro-industrial biomass waste. The objective of this study was to evaluate the effect of the inoculum/substrate ratio on the Biochemical Methane Potential (BMP) of grape marc. The experiment was performed in laboratory scale through a system of reactor bottles in batches, removing a set of triplicate flasks for sampling and analysis every 48 hours, with the test lasting 12 days. The reactors contained residue, inoculum and 20% of nutritive solution, maintaining 20% of headspace. The reactors were incubated in an incubator at a mesophilic temperature (35 ± 2°C) and shaken manually every 24 hours. Three different inoculum/substrate (I/S) ratios of 0.75, 1.5 and 3 were used to evaluate the methane yield, organic removals and at the end of degradation the morphology of the bacterial community was evaluated by means of scanning electron microscopy. The I/S 3 ratio provided the best results for loading anaerobic systems, indicating that grape marc presents potential for biological treatment through anaerobic digestion

Fabricação de queijos utilizando ervas aromáticas: validação e transferência de tecnologia.

Processamento de queijo muçarela de leite de cabra pelo método de fermentação.

A elaboração de queijo Muçarela caprino obtido pelo método de fermentação é uma alternativa viável para a inserção de derivados lácteos diferenciados no Semiárido brasileiro, agregando valor ao leite de cabra produzido na maior bacia leiteira caprina do Brasil. A produção de queijo Muçarela de leite de cabra, pode ser uma opção para incentivar a comercialização e o consumo de lácteos caprinos, principalmente em decorrência da Muçarela ser um dos queijos mais consumidos e utilizados na culinária nacional.SELOS ODS 2, 8, 9, 12, 17
