�ber Polyphenole im Brauproze� [PDF]

open access: possibleZeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1978
Analytical methods for the determination of polyphenols of malt, barley, hop, wort, and beer are described. Malt or barley tannins has hitherto not received as much study as hop tannin. Polyphenols or tannins are classified. Studies on non-biological hazes are discussed in relation to the haze problem in brewing.

Polyphenols

2017
This chapter outlines the current trends and innovative techniques in the processing of natural polyphenolic compounds and how emerging technologies affect the functionality of these nutraceutical and functional food components. The bioavailability of polyphenols as nutrients, their transformations by intestinal microbiota as well specific interactions

Polyphenols and Tuberculosis

2014
Polyphenols are secondary metabolites produced by higher plants. Dietary polyphenols represent a wide variety of compounds that occur in fruits, vegetables, wine, tea, extra virgin olive oil, chocolate, cocoa products, dry legumes, cereals and honey. Mycobacterium tuberculosis is an airborne, infectious disease caused by bacteria that primarily affect ...

Polyphenols and bioavailability: an update

Critical Reviews in Food Science and Nutrition, 2019
Based on many cell culture, animal and human studies, it is well known that the most challenge issue for developing polyphenolics as chemoprevention or anti-diabtetic agents is the low oral bioavailability, which may be the major reason relating to its ambiguous therapeutic effects and large inter-individual variations in clinical trials.

Nutrigenomics and polyphenols

2018
The human body is continuously exposed throughout life to a complex mixture of foods, composed by thousands of chemicals, many of them unknown. Each nutrient can have different biochemical targets and physiological functions. Moreover, the assessment of individual nutrients effect on health is complex since nutrients are consumed on a dietary mixture ...

Polyphenols and Flavonoids

2019
Majority of the plants used in traditional system of medicine are rich in polyphenols and flavonoids which not only regulate the growth of plants but also are rich source of phytochemicals employed in human and animal health. Polyphenols and flavonoids have been advocated as nutraceuticals in human medicine to treat certain modern lifestyle diseases ...

Polyphenolic Antioxidants and Health

2012
Oxidative stress is believed to play a pivotal role in several physiologic (aerobic metabolism, immunologic responses, cellular signaling, regulation of gene expression, cell differentiation) [1] and pathologic (atherosclerosis, tumorigenesis, neurodegenerative diseases, etc.) processes. Antioxidants react with oxygen free radicals protecting the cells

Polyphenolic Composition of Raisins

Journal of Agricultural and Food Chemistry, 2000
The polyphenolics of raisins were extracted, separated by HPLC, and characterized by their UV-vis spectra, and their concentrations measured. Color measurements and browning indices were also determined. Samples (n = 20) included sun-dried, dipped, and golden raisins. Comparisons were also made with fresh and frozen Thompson Seedless grapes.

Antihypertensive Role of Polyphenols

2012
Hypertension is considered the most important risk factor in the development of cardiovascular disease. Considerable evidence suggests that oxidative stress, which results in an excessive generation of reactive oxygen species (ROS), plays a key role in the pathogenesis of hypertension.
