Effect of different plant fibers on the elimination of undesirable compounds in red wine. Correlation with its polysaccharide composition

Abstract

The presence of undesirable compounds in wines, such as OTA, biogenic amines and pesticides residues, affects wine quality and can cause health problems for the consumer. The main tool that a winemaker has to reduce their content in the wine is fining. However, some of the fining agents commonly used in the winery can cause allergies or even increase the protein content in the wine, increasing the turbidity. To avoid these problems, the use of plant fibers may be an alternative, such as those from grape pomace[1] or other plant origins.

The objective of this work was to determine the effect of two plant fibers in the reduction of undesirable compounds and to correlate their behavior with their polysaccharide composition, analyzed using comprehensive microarray polymer profiling (CoMPP). [2] The results showed that a white grape pomace fiber presented the highest capacity for histamine reduction in wine and also reduced large amounts of pesticides, although the highest effectiveness to remove pesticides residues was found when a cereal fiber was used. Looking for a correlation between effectivity and composition, we could see how grape fiber contained high contents of pectic polysaccharides, xyloglucans and arabinogalactan proteins (AGP) whereas the behavior of cereal fiber can only be associated to its xylan content, since the pectic polysaccharides were absent. This was a surprising finding since it is known that fibers may affect wine color due to the high affinity of their polysaccharides, especially pectic polysaccharides for polyphenols, but when looking at the effect of these two fibers on wine chromatic characteristics, the cereal fiber largely affected wine color, more than the grape pomace fiber, so another factor, such as the porosity of the fiber, must also be an important fact regarding their effectiveness.

Addition of glutathione-rich inactivated yeasts to white musts: effects on wine composition and sensory quality

Glutathione plays a key role in preventing some oxidative processes during winemaking. This molecule limits the must enzymatic oxidation, reacts with caffeic acid and generates a colourless compound that prevents subsequent browning. It also has a protective effect on wine aroma, preventing the oxidation of the volatile compounds with a high sensory impact.

Acceptability of canned wines: effect of the level of involvement of consumers and type of wine

In recent years there has been a growing demand for alternative packaging designs in the food industry focused on diminishing the carbon footprint. Despite the environmental advantages of cans versus bottles, the traditional environment of wine has hindered the establishment of less contaminant containers. In this context, the objective of this study was to understand and generate knowledge about consumers´ perception of canned wines in comparison to bottled wines.

Study of Spanish wine sensory analysis data over a 3-year period

This study presents an investigation based on sensory analysis data of Spanish wines with geographical indications collected over a three-year period. Sensory analysis plays a crucial role in assessing the quality, characteristics, and perception of wines. The trained tasting panel at Dolmar Laboratory, accredited for objective sensory evaluation of wines since 2016, has been tasting over 5000 wines. However, it is since 2021, when a computer application for tastings was developed, that the digitalization of data allows for detailed statistical analysis of the results.

Analysis of the interaction of melatonin with glycolytic proteins in Saccharomyces cerevisiae during alcoholic fermentation 

Melatonin is a bioactive compound with antioxidant properties, that has been found in many fermented beverages, such as beer and wine [1]. Indeed, it has been shown that yeast can synthesize melatonin during alcoholic fermentation, although its role inside the cell, as well as the metabolic pathway involved in its synthesis, is still unclear [1]. Recent studies showed that during fermentation, melatonin interacts with different proteins of the glycolytic pathway in both Saccharomyces and non-Saccharomyces yeast, for instance glyceraldehyde 3-phosphate dehydrogenase, pyruvate kinase or enolase [2].

Evaluation of interception traps for capture of Xylotrechus arvicola (Coleoptera: Cerambycidae) in vineyards varieties from Protected Denomination of Origin León

Xylotrechus arvicola (Coleoptera: Cerambycidae) is a pest in vineyards (Vitis vinifera) in the main Spain wine-producing regions with Protected Denomination of Origin (PDO). The action of the larvae, associated to the spreading of wood fungi, causes damage especially in important varieties of V. vinifera. X. arvicola females lay eggs concentrated in cracks or under the rhytidome in the wood vines, which allows the emerging larvae to get into the wood and make galleries inside the plant being then necessary to prune intensively or to pull up the bored plants (1). The objective of the study was to evaluate captures of X. arvicola insects in five varieties of V. vinifera in PDO León.
