| The present study extracted pectin from Pink Lady apples (Malus pumila), which present at physiological maturity an average 50% of red-color coverage, to assess whether this variety is characterized by a high (HM) or low methoxyl value (LM). The raw materials were obtained from the Marengo farm, Los Niches, Curicó province, in the south-central region of Chile. Acid hydrolysis was used and the material was then subjected to sensory analysis, evaluating the organoleptic characteristics of pectin. The pectin was extracted with citric acid, which was tested under three pH conditions (2.5, 3.0 and 3.5, the latter corresponding to the natural pH of apples) for 60 and 90 min and subjected to a constant temperature of 90 °C. The degree of esterification (DE) of... |

| The general objective of this research was to evaluate the color stability of pickled asparagus with time. The salt addition time, with respect to the color maintenance of the asparagus sprouts, and the sensory acceptability of the final products were determined in this study. Discarded asparagus stems from Longaví (Linares province), located in the central-south area of Chile, were used. The pickle preparation and sensory evaluation analysis were carried out at the Universidad Católica del Maule in Curicó, Chile. Microbiological analysis was carried out separately at a private laboratory. The pickles were prepared with three different salt concentration treatments: 2.5, 7 and 9%. The sensory and microbiological attributes were evaluated after three... |
