Características físico-químicas de sucos integrais elaborados a partir de uvas da espécie Vitis rotundifolia

Abstract: Resumo Objetivou-se com este trabalho avaliar o perfil físico-químico de sucos elaborados com uvas das variedades Vitis rotundifolia Regale, Noble, Summit e Carlos. O trabalho foi realizado na Epagri-Videira/SC, nas safras 2016, 2017 e 2018. O delineamento experimental utilizado foi um fatorial duplo (variedade × safra), de forma inteiramente casualizada e com três repetições. As análises físico-químicas realizadas foram: acidez total (AT), teor de sólidos solúveis (SS), relação SS/AT, pH, açúcares redutores, … Show more

“…The very high acidity and lower sweetness resulted in the imbalance between sweet and acid, culminating in the lowest global impression. Similar results were found by Bender et al (2019) in C30 juices, which showed an imbalance due to greater acidity and low sweetness, reflected in the global appreciation, in both extraction systems. Rizzon et al (2018) explain that a sweetness and acidity equilibrium is fundamental for the juice quality, with the sweet flavor collaborating with the structure, while the acidity participates in the freshness and conservation of the product.…”

“…Although the pans are easy to use, have a low cost of implantation and provide good quality juices, this process can lead to an incorporation of exogenous water, due to the condensation of the steam used to extract the juice (Bender, Souza, Caliari, Malgarim, & Camargo, 2019;Bresolin, Gularte, & Manfroi, 2013;Marcon et al, 2016). The percentage of water incorporation in the juices made through the extraction pans varies from 7.56% to 20.7% (Marcon et al, 2016).…”

“…Nos sucos, elas apresentam sabor doce, ácido, adstringente e aroma de fruta cozida. Contudo, os sucos fabricados a partir desse tipo de uva possuem grande potencial nutracêutico, facilitando a sua comercialização (BENDER et al, 2019) Obtida através da fermentação alcoólica da uva fresca e madura ou pelo suco de uva fresco, o vinho tem definição bioquímica devido sua caracterização proveniente da fermentação alcoólica dos açúcares de suco de uva pelas leveduras e pelas bactérias láticas. São substâncias que constituem o vinho: os compostos fenólicos, pectinas, compostos voláteis, aromáticos, vitaminas, sais, anidrido sulfuroso, açúcares, álcoois, sais de ácidos minerais e orgânicos, ácidos orgânicos, gomas e mucilagens, substâncias nitrogenadas e pigmentos (LOCATELLI, 2017).…”
