L., , as a Source of Bioactive Compounds of Antioxidant Properties.

Natural bioactive compounds play an important role in the prevention of various diseases. The exotic fruits L. (star fruit), (tamarillo) and (camu-camu) can be valuable sources of phytochemicals with antioxidant properties.

Impact of European Bison Grazing ( (L.)) on Species and Functional Traits of Carabid Beetle Assemblages in Selected Habitats in Poland.

Currently we are observing a drastic decline in insect fauna on a large scale. Grazing is regularly used as an ecological method of protecting or restoring special biotopes that are important for species conservation. The European bison ( (L.

β-Carbolines in Experiments on Laboratory Animals.

Some studies have ascribed a protective effect against neurodegenerative diseases to the β-carbolines harman (H) and norharman (NH), which occur mostly in coffee and coffee substitutes. We determined the concentrations of β-carbolines and undesirable compounds (such as acrylamide) in roasted coffee substitute ingredients and found that chicory coffee was optimal. Two in vivo experiments were conducted with seventeen-month-old male Sprague Dawley rats fed a diet with the addition of pure carboline standards in the first stage, and chicory in the second.

Bioactivity of selected materials for coffee substitute.

Epidemiological studies have suggested that coffee consumption is negatively correlated with the incidence of Parkinson's disease. Coffee contains relatively high levels of β-carbolines, which have been ascribed neuroactive effects in humans however the positive or negative effect has not been confirmed yet. Two ingredients with applications as coffee substitutes-chicory, which is traditionally used in this way, and artichoke-were considered in this study both from the neuroactive point of view but also in relation to the other bioactive compounds that result from their thermal processing.

Antioxidant Properties and Phenolic Compounds of Vitamin C-Rich Juices.

Unlabelled: Many studies have shown that bioactive compounds, for example, polyphenols, and so on can play an important role in reducing oxidative stress and protect against various diseases. The sources of these compounds in the human diet include mainly fruit and good quality fruit juices, which may contain polyphenols but also other phytochemicals such as vitamin C. The purpose of the study was to analyze the antioxidant properties of vitamin C-rich juices, which underwent mild processing.

Phenolic compounds reduce formation of N-(carboxymethyl)lysine and pyrazines formed by Maillard reactions in a model bread system.

This study had the objective of determining the antiglycation activity of phenolic compounds (PCs) ((+)-catechin, quercetin, gallic, ferulic, and caffeic acids) added to a model bread with regards to the inhibition of N-(carboxymethyl)lysine (CML) formation. PCs were found to significantly reduce CML (31.77%-87.

Bioactive β-carbolines norharman and harman in traditional and novel raw materials for chicory coffee.

The β-carboline compounds norharman and harman exhibit neuroactive activity in the human body. Chicory coffee has proved to be a source of β-carboline compounds. This study assessed the norharman and harman contents of traditional and novel raw materials for the production of chicory coffee, as well as in samples of chicory coffee with novel additives.

Chlorogenic acid in raw materials for the production of chicory coffee.

Background: Chicory coffee is produced from traditional raw materials. Other materials are added to improve its aroma. The aim of this study was to test new raw materials with a high content of chlorogenic acid (CGA) as the criterion for their selection.

Odor active compounds content in spices and their microencapsulated powders measured by SPME.

Within this study, main odorants of marjoram and thyme (linalool and thymol) were determined in spices and microencapsulated powders using solid-phase microextraction (SPME). Analyses were conducted on selected batches of spices before and after decontamination and on microencapsulated powders prepared for technological purposes (improvement of aroma in decontaminated spices). Conditions of SPME analyses were determined for individual compounds and matrices.
