Resveratrol (RT) has been suggested to have a protective effect against cardiovascular diseases. We analyzed the concentration of RT in red wine samples at early stages of aging and old vintage wines, by a combination of normal and reverse phase HPLC. Although we have previously reported that RT contents in red wine samples, made from eight grapevines grown in Hokkaido, Japan, after malolactic ...

Wine industry is engaged in finding technological ways to decrease alcohol concentration in wines without spoiling their organoleptic properties. Such challenge requires, among other strategies, modification of the yeast strains carrying out the fermentation. In this issue of Microb. Biotechnol., Goold and colleagues have reviewed one of the most straightforward yeast modification, altering its...

ABSTRACT Biogenic amines are group of organic, basic, nitrogenous compounds that naturally occur in plant, microorganism, and animal organisms. Biogenic amines are mainly produced through decarboxylation of amino acids. They are formed during manufacturing of some kind of food and beverages such as cheese, wine, or beer. Histamine, cadaverine, agmatine, tyramine, putrescine, and β-phenylethylam...

Studies have shown that the type of packaging can affect quality and physico-chemical features foods stored over a longer period time. Important characteristics wines change storage are alcoholic strength, amount acidity or sulfur dioxide, relative density total dry extract. The aim this paper was to determine compare properties red (Cabernet sauvignon, Frankovka, Merlot Pinot noir), one year i...

The fruits of wild berries, viz. Berberis lycium Royle, Pyrus pashia Buch.-Ham ex D. Don, Actinidia deliciosa (A.Chev.) C. F. Liang & A. R. Ferguson, Syzygium jambos (L.) Alston, Emblica officinalis Gaertn., Prunus cerasoides D. Don, Rubus ellipticus Sm, Crataegus sp. and Citrus karma Raf. were collected from the forests of various regions of Kangra, Himachal Pradesh (India) for preparation of ...

The most common way to produce red wine is through the use of Saccharomyces cerevisiae strains for alcoholic fermentation and lactic acid bacteria for malolactic fermentation. This traditional winemaking methodology produces microbiologically stable red wines. However, under specific conditions off-flavours can occur, wine quality can suffer and human health problems are possible, especially af...

Alcohol beverages prior to White contact originated with the Mayan and the Aztec Nations and spread to the American Indians of the Southwest. Surprisingly, there are a number of accounts of alcohol use among other American Indians and Alaska Natives. Beverages were limited to wine and beer, and included: balche, pulque, and "haren a pitahaya" wines, tulpi beer and other beverages. White contact...

Abstract Aroma components of wines play an important role in the sensory quality wines. In our paper we investigate effect commercially available yeast nutrients under different fermentation parameters. Caproic acid, caprylic capric and fatty acid esters were used as markers alcoholic process. The optimal temperature for white was at 15–16 °C, case examined lower concentrations acids found this...

The most popular methodology to make red wine is through the combined use of Saccharomyces cerevisiae yeast and lactic acid bacteria, for alcoholic fermentation and malolactic fermentation respectively. This classic winemaking practice produces stable red wines from a microbiological point of view. This study aims to investigate a recent red winemaking biotechnology, which through the combined ...
