Resumo: | Mouthfeel sensations such as astringency, texture, acidity, heat and body, influence the sensory character of wines, in particular red wines. Several studies indicate that the type of closures used in bottling wine may influence the sensory profile of the wine, through oxygen permeability, which influences oxidation reactions, and/or through the reaction of the closure material itself with the wine during storage. The present study was carried out in the context of a collaboration between Amorim Cork, SA, and Escola Superior de Biotecnologia-UCP. The main objective of this collaboration, held between March and December 2023, was to study the impact of different cork stoppers mainly in mouthfeel sensations of bottled red wines from different countries and regions. To this end a sensory panel was selected and trained, and sensory tests (duo-trio discrimination tests and descriptive sensory tests) were carried out to detect sensory perceptible differences between commercial wines bottled with different closures and to determine their in-mouth sensory profile. Additionally, the same wines were subjected to physical-chemical analysis performed in external laboratories. The measured physical-chemical parameters were free and total sulfur dioxide, the total polyphenol index (TPI), color intensity (CI), wine color tonality (CT) and volatile organic compounds (VOCs): aldehydes, furans, ketones and some esters. These parameters were previously described in the literature as indicators of the oxidation state of the wine and may be influenced by packaging conditions, namely the closures used in this study. The results thus obtained were statistically analyzed using a Kruskal-Wallis test. The sensory discrimination tests performed uncovered the existence of perceptible differences between the wines bottled with different stoppers in six of the eight sensory sessions held, mainly between the wine bottled with natural cork stoppers and with the technical cork stoppers (microagglomerated or discs). These differences were related to differences in the intensity of sensory mouthfeel attributes of these wines, as shown by uni and multidimensional analysis performed of the sensory profile results. For most wines bottled with different stoppers no significant differences regarding free and total SO2, total polyphenol index and colour parameters (CI and CT) were observed. Significant differences were found for some wines bottled with different stoppers regarding some VOCs (phenylacetaldehyde, decanal, β-cyclocitral, furfural, hexyl acetate, diethyl succinate, ethyl octanoate and ethyl decanoate). In both cases, however, none of the physical-chemical parameters analyzed allowed the identification of any trend relating the differences in the wine composition with the cork type. |

Vários estudos indicam que o tipo de vedante usado no engarrafamento do vinho pode influenciar o seu perfil sensorial, através da permeabilidade ao oxigénio, que influencia as reações de oxidação, e/ou através da reação do material do vedante com o vinho durante o armazenamento. O presente estudo foi realizado no contexto de uma colaboração entre a Amorim Cork, SA, e a Escola Superior de Biotecnologia-UCP. O principal objetivo deste trabalho, realizada entre março e dezembro de 2023, foi estudar o impacto de diferentes rolhas principalmente nas sensações na boca de vinhos tintos engarrafados de diferentes países e regiões. Para isso, um painel sensorial foi selecionado e treinado, e testes sensoriais (testes de discriminação duo-trio e testes descritivos) foram realizados para detetar diferenças percetíveis entre vinhos comerciais engarrafados com diferentes vedantes e para determinar seu perfil sensorial na boca. Adicionalmente, os mesmos vinhos foram submetidos a análises físico-químicas realizadas em laboratórios externos. Os parâmetros físico-químicos medidos foram, o dióxido de enxofre livre e total, o índice total de polifenóis (TPI), a intensidade de cor (CI), a tonalidade de cor do vinho (CT) e os compostos orgânicos voláteis (VOCs): aldeídos, furanos, cetonas e alguns ésteres. Esses parâmetros foram descritos anteriormente na literatura como indicadores do estado de oxidação do vinho e podem ser influenciados pelas condições de embalagem, nomeadamente pelos vedantes usados neste estudo. Os resultados obtidos foram analisados estatisticamente usando um teste de Kruskal-Wallis. Os testes de discriminação sensorial realizados revelaram a existência de diferenças percetíveis entre os vinhos engarrafados com diferentes vedantes em seis das oito sessões sensoriais realizadas, principalmente entre o vinho engarrafado com rolhas de cortiça natural e com rolhas técnicas (microaglomeradas ou discos). Essas diferenças estavam relacionadas com diferenças na intensidade dos atributos sensoriais de sensação na boca desses vinhos, como mostrado pela análise uni e multidimensional realizada dos resultados do perfil sensorial. Para a maioria dos vinhos engarrafados com diferentes vedantes, não foram observadas diferenças significativas em relação ao dióxido de enxofre livre e total, índice total de polifenóis e parâmetros de cor (CI e CT). Foram encontradas diferenças significativas para alguns vinhos engarrafados com diferentes vedantes em relação a alguns VOCs (fenilacetaldeído, decanal, β-ciclocitral, furfural, acetato de hexilo, succinato de dietilo, octanoato de etilo e decanoato de etilo). Em ambos os casos, no entanto, nenhum dos parâmetros físico-químicos analisados permitiu a identificação de qualquer tendência relacionando as diferenças na composição do vinho com o tipo de rolha.Faria, Maria João Nepomuceno P.
