Hop ( L.) extract reverts glycaemic imbalance and cognitive impairment in an animal model of obesity.

The rates of overweight and obesity around the world have increased in past years. The body's adipose tissue stimulates the antioxidant and oxidation imbalance capacity at the cellular level. This scenario favors an inflammatory low-grade systemic condition starting with insulin resistance, which in turn may involve diabetes mellitus type 2 and cognitive decline afterward.

Paraprobiotics obtained by six different inactivation processes: impacts on the biochemical parameters and intestinal microbiota of Wistar male rats.

This study investigated the effects of feeding paraprobiotics obtained by six processes [heat, ultrasound, high pH, low pH, irradiation and supercritical carbon dioxide (CO)] on biochemical parameters and intestinal microbiota of Wistar male rats. Daily administration of paraprobiotics did not affect ( ≥ 0.05) the food intake, body weight, glucose and triglycerides levels, expression of antioxidant enzymes or thermal shock proteins in comparison to the control.

Quantifying the impact of eight unit operations on the survival of eight Bacillus strains with claimed probiotic properties.

This study assessed the impact of eight unit operations [slow pasteurization, high-temperature short time (HTST) pasteurization, cooking, baking, drying, fermentation, supercritical carbon dioxide (CO), irradiation and extrusion] in different food matrices (milk, orange juice, meatballs, bread, crystallized pineapple, yogurt, orange juice, ground black pepper, snacks, and spaghetti) on the resistance of eight (Bacillus flexus Hk1 Bacillus subtilis Bn1, Bacillus licheniformis Me1, Bacillus mojavensis KJS3, Bacillus subtilis PXN21, Bacillus subtilis PB6, Bacillus coagulans MTCC 5856 and Bacillus coagulans GBI-30, 6086) Bacillus strains with claimed probiotic properties (PB). The number of decimal reductions (γ) caused by the unit operations varied (p < 0.05) amongst the PB.

Extraction of bioactive compounds from defatted passion fruit bagasse (Passiflora edulis sp.) applying pressurized liquids assisted by ultrasound.

Passion fruit bagasse is a rich source of phenolic compounds, including piceatannol, a stilbene to which several biological activities are conferred. This work reports the application of pressurized liquid extraction (PLE) assisted by ultrasound (US) to intensify the extraction of phenolic compounds from defatted passion fruit bagasse (DPFB). PLE at different temperatures (65-75 °C) without and with different US powers (240-640 W) was performed to investigate the mechanism of the assisted process.
