Cooking vegetables in microwave bags is becoming a popular domestic cooking method, being relevant to know how this method affects health-promoting phytochemicals of staples such as broccoli. The aim work was study the effect bag versus conventional microwaving on bioactive compound content (glucosinolates and hydroxycinnamic acid derivatives) other quality parameters (such antioxidant capacity...

The aim of this work was to investigate the effect of phenolic acids on cell membrane permeability of lactic acid bacteria from wine. Several phenolic acids were tested for their effects on the cell membrane of Oenococcus oeni and Lactobacillus hilgardii by measuring potassium and phosphate efflux, proton influx and by assessing culture viability employing a fluorescence technique based on memb...

Reactivity of (2E)-3-(3,4-dihydroxyphenyl)prop-2-enoic acid (caffeic acid), classified as a hydroxycinnamic (HCA) derivative, toward electrogenerated superoxide radical anion (O2•−) was investigated through cyclic voltammetry, in situ electrolytic electron spin resonance spectrometry, and ultraviolet–visible spectrometry N,N-dimethylformamide (DMF), aided by density functional theory (DFT) calc...

Abstract Cassia auriculata is an Ayurvedic medicinal herb, traditionally indicated for diabetes and hyperlipidemia. Several works have demonstrated its antioxidant, antidiabetic anti-hyperlipidemic activity in vivo vitro . Nevertheless, only a few investigated phytochemical composition, specifically, the polyphenolic composition of various plant parts that are used. In this work, C. leaves, flo...

We analyzed the red-fleshed apple cultivar ‘Baya Marisa’ and compared it with traditional, white-fleshed ‘Golden Delicious’. The objective of this study was to compare sugars, organic acids, phenolic compounds widely known consumed In addition, flesh firmness, color, soluble solid content studied. A total 46 were quantified identified, some for first time in apples. showed that (TAPC) 1.6× high...

Several 2,3-unsaturated carboxylic acids, such as trans-cinnamic acid and its derivatives, were found to be halogenated by chloroperoxidase of Caldariomyces fumago in the presence of hydrogen peroxide and either Cl- or Br-. Cinnamic acid, 4-hydroxycinnamic acid, 4-methoxycinnamic acid, and 3,4-dimethoxycinnamic acid were suitable substrates of chloroperoxidase, and were converted to 2-halo-3-hy...

Imaging Matrix Assisted Laser Desorption Ionization Mass Spectrometry provides a new and powerful tool to analyse the distribution of metabolites within plant tissues. The two matrices alpha-cyano-4-hydroxycinnamic acid (alpha-CHCA) and 9-aminoacridine provide a useful combination that allows the measurement of amino acids, sugars, and phosphorylated metabolites. Results are presented showing t...
