Abstract

OLIVERO, Rafael E; AGUAS M., Yelitza  and  CURY R., Katia. Evaluation of effect of various strains of yeast (Montrachet, K1-V1116, EC-1118, 71B-1122 y IVC-GRE ®) and clearer on the sensory attributes orange wine (Citrus sinensis). Rev. colomb. biotecnol [online]. 2011, vol.13, n.1, pp.163-171. ISSN 0123-3475.

In this Wort was evaluated the effect of different types of strains of yeast (Montrachet, K1-V1116, EC-1118, 71B-1122 y IVC-GRE) over the sensorial attributes of orange wines were also studied. These attributes were measured in a modified scale of UC Davis. By using an order test in order to know the best cleared treatment, it was determined that gelatin by itself does not cause any effect over the general quality attribute, but the combination of gelatin and microfiltration, cause a positive effect over the orange wine appearance. The five wines treated with different yeasts presented significant differences on individual scores, total acidy, flavor and general quality of the UC Davis scale. The sensorial evaluation of wines showed that the yeast K1-V1116 produced the best rated orange wine. This wine was significantly different over many attributes when compared with the other wines evaluated by the sensorial panel.

Keywords : Orange wines; strains of yeast; sensorial attributes.
