Strategies for Increasing the Release of Pigments in Red Wine
… addition, and fermentation temperature, on phenolic compound extraction (total phenol, tannin and anthocyanin) during the production of Paso Robles’ Cabernet Sauvignon wine. Analyses on phenolic compounds were completed during alcoholic fermentation and barrel aging over the course of …

The Acute Effects of Nut Ingestion on Plasma Levels of Polyphenol Compounds, Biomarkers of Antioxidant Status, and Lipid Peroxidation
<p>Nuts are rich sources of polyphenolic compounds and nutrients, which have antioxidant capacity. To assess the acute effect of treatment diet (75% of energy from nuts (walnut or almond) and control diet (habitual diet with no nut consumption) in healthy subjects on plasma total phenol content, …

Use of antioxidant activity and flavonoid levels to assess the quality of commercially available solid dose Sutherlandia frutescens products
… and environmental humidity conditions and total phenol, antioxidant and chromatographic analysis was conducted on these samples. Samples of each of the SCP were hydrolyzed using HCL and then analyzed using HPLC to test the stability of the flavonoids present in each product. The SCP …

Physicochemical assessment of microbial communities of fermented olives in Namibia using culture dependent and independent methods
… produced mostly by spontaneous fermentation . A total of 30 olive samples were collected from two different sites (Noab and Shalom) from February to October 2018. Total plate count, total phenolic content, total LAB and total yeast and mould count were also determined over 5 months to study the …

Phytochemical, antimicrobial and cytotoxicity evaluation of rhizome extracts of Hydnora Abyssinica from Acacia Nigrences host
… screening was done by colorimetric tests, while total phenol content (TPC), total flavonoid content (TFC) and total tannin content (TTC) were determined using spectrophotometric methods. Antimicrobial activity of the extracts was determined by means of agar diffusion and broth microdilution …

Potential cardioprotective effect of chronic, moderate consumption of reduced-alcohol wine in a rat model of pulmonary hypertension
… determined for 4 weeks by analysing ORAC values, total phenolic concentration, anthocyanin and catechin concentrations. Prior to randomisation, and at day 28, echocardiography (VEVO 2100, Visualsonics Inc.) was performed to evaluate pulmonary artery acceleration time (PAAT), an accurate estimate …

Separation of solvents from selected biopolymeric matrixes and aqueous mixtures by ultrasound
… Distillation accounts for ~95% of the total separation energy used in the refining and chemical-processing industries (Leeson et al., 2017). Unfortunately, the energy efficiency of a commercial distillation column is fairly low, with a typical thermodynamic efficiency of less than 10% …
