The Campanha Gaucha region, southern Brazil, has received significant investments in Viticulture during the last decades, especially for production of quality wines. However, implementing American and hybrid grapes this region constitutes opportunity to supply increasing demand grape juice market Brazil. Juices two varieties, “Bordô” “Concord”, from locations, Dom Pedrito Santana do Livramento, were analysed terms following physico-chemical aspects: total city, volatile acidity, density, pH,...
O objetivo deste trabalho foi avaliar o desempenho agronômico de dois genótipos morangueiro submetidos a diferentes formas cultivo em sistema orgânico produção. Os utilizados foram CREA FRF LAM 269.19 (dia curto) e 114.01 neutro). morangueiros cultivados solo, calhas, slabs ou vasos. delineamento experimental com arranjo casualizado bifatorial. As avaliações foram: datas início floração, frutificação colheita; aspectos da planta frutas; produtivos - produção total; número frutas, comercial;...
The volatile fraction of mate (Ilex paraguariensis) tea—specifically Brazilian chimarrão type, which has an odor profile comprising distinctive fresh, green, grass, and herbal notes—was investigated. Hydrodistillation in a Clevenger apparatus was employed order to extract volatiles from the tea matrix. Headspace–solid-phase dynamic extraction (HS-SPDE) two types infusions this tea—a simple single infusion traditional preparation consecutive infusions. Volatiles were analyzed by gas...
The objective of the present study was to evaluate grape juices from different cultivars obtained by two technologies: steam juicer system (S1) and enzymatic (S2). beverages were evaluated for physicochemical sensory characteristics their adequacy identity quality standards whole juice. Experiments carried out in 2018 2019 harvests with BRS Rúbea (RUB), Cora (COR), Violeta (VIO), Carmem (CAR), Magna (MAG), Bordô (BOR), Isabel (ISA), Precoce (IP), Concord (CON), Clone 30 (C30) SCS 421 Paulina...
Abstract The objective of this work was to evaluate the physicochemical composition juices from 'Bordô' and 'BRS Cora' grapes grown in an organic production system Serra do Sudeste region, Southern Brazil, as well compare cultivar results with data other producing regions requirements Brazilian regulation for whole grape juice. used came a commercial vineyard, especifically 2016-2017, 2017-2018, 2018-2019 cycles. were prepared by steam drag method evaluated their composition. fruit showed...
Peach is a climacteric highly-perishable fruit whose post-harvest preservation relies largely on cold storage. The combination of the last with other technologies allows to extend shelf life this product. One alternative utilization salicylic acid, natural compound involved in many physiological phenomena such as resistance against diseases and ripening. Considering these facts, objective present work was evaluate effect pre-harvest application acid solutions quality ‘Chimarrita’ peaches...
El Niño-Southern Oscillation (ENSO) is an important source of year-to-year fluctuations in the whole global climate system and southern Brazilian climate.El Niño events affect this region, imposing unfavorable weather conditions (rainy/humid/overcast) during critical grapevine phenological stages, compromising yields current following crop seasons.The analysis 29 cycles revealed patterns about grape yield oscillations Santana do Livramento, Campanha Gaúcha, RS, Brazil.Yield deviations showed...
O presente estudo investigou o potencial qualitativo de sucos uvas Concord e Bordô elaborados na região da Campanha Gaúcha. Para tanto, três experimentos foram desenvolvidos, avaliando-se comparando-se: uva produzidos em diferentes locais Gaúcha (Experimento 1); Serra 2); por sistemas extração 3). A qualidade dos foi avaliada análises físico-químicas compostos bioativos. Os fatores que mais influenciaram dentro a variedade uva, ciclo produtivo e, último, local produção (dentro região). com...
The climatic aspects influence the physicochemical characteristics of grapes, interfering in quality mainly period cluster maturation. objective this study was to analyze conditions and climatological variables, correlating with viniferas Chardonnay Tannat, from 2019, 2020, 2021 2022 harvests, evaluate a possible interference composition these consequently, wines be produced, municipality Dom Pedrito, Region Campanha. Tannat grapes were harvested at stage full maturation, then analysis...
Objetivou-se com este estudo avaliar a influência dos processos de extração arraste vapor (S1) e enzimático (S2) sobre composição polifenólica sucos uva das variedades Bordô, Concord BRS Violeta produzidos na região do Vale Rio Peixe-SC. Foram identificados quantificados 12 compostos fenólicos por cromatografia líquida alta eficiência detector arranjo diodos (CLAE-DAD), que diferiram sua concentração acordo variedade sistema extração. A partir análises componentes principais observou-se ‘BRS...
Meteorological conditions are fundamental factors in the development of viticulture anywhere world. Considering this, viticultural climate and variability Santana do Livramento, Campanha Gaúcha, Brazil, was characterized based on three bioclimatic indices defined by Geoviticulture Multicriteria Climatic Classification (MCC) System – cool night index (CI), heliothermal (HI) dryness (DI) addition to a modified (DImodified). The observed correlated with phases El Niño-Southern Oscillation...
ABSTRACT: The Campanha Gaúcha region has recently (2020) received an Indication of Provenance (‘IP Gaúcha’) for wines and sparkling wines. Scientific data research developed during the last decades could provide necessary information this first characterization area. Nevertheless, there is a lack detailed about composition In study, five white different grape varieties (Riesling, Gewürztraminer, Semillon, Sauvignon Blanc Chardonnay) produced in 2018 vintage were collected directly from...
