Abstract

Fresh-cut apples were subjected to mild vacuum impregnation (Vacuum pressure=67.7 mbar). M0: 30 °Brix honey solution (HS); M0.5: HS+0.5% citric acid (CA)+0.5% ascorbic acid (AA); and M1: HS+1% CA+1% AA were used as osmotic solutions. Changes in soluble solids (SS), pH, firmness, color (∆E*ab), total phenolic and vitamin C content, and antioxidant capacity were evaluated on days 0 and 7 of storage at 1.5 °C. Mass transfer parameters were calculated. The best results were obtained with the M1 treatment. Vacuum-impregnated fresh-cut apples gained solids (3.3%) and weight (1.6%) and lost water (1.8%). The following modifications were observed on day 0: an increase of SS (26%), a reduction in firmness (14%), a slight color change (∆E*ab=3.3), a great increase in vitamin C content (31 times higher than in fresh-cut fruits) and increases in total phenolic content and antioxidant capacity (27% and 77%, respectively). On day 7 of storage, an additional reduction of firmness was observed, but the other attributes were maintained or increased. The M1 treatment is an appropriate alternative for processing fresh-cut apples and obtaining improved healthy attributes.

用含蜂蜜的渗透溶液真空浸渍刚切的苹果

新鲜切开的苹果进行轻度真空浸渍(真空压力=67.7毫巴)。M0: 30°白蜡蜂蜜溶液(HS);M0.5: HS+0.5%柠檬酸(CA)+0.5%抗坏血酸(AA);M1: HS+1% CA+1% AA作为渗透溶液。在1.5°C条件下保存第0天和第7天，测定可溶性固形物(SS)、pH、硬度、颜色(∆E*ab)、总酚和维生素C含量以及抗氧化能力的变化。计算了传质参数。以M1处理效果最好。真空浸渍的新鲜切苹果的固体含量增加了3.3%，重量增加了1.6%，水分损失了1.8%。在第0天观察到以下变化:SS增加(26%)，硬度降低(14%)，颜色略有变化(∆E*ab=3.3)，维生素C含量大幅增加(比鲜切水果高31倍)，总酚含量和抗氧化能力分别增加27%和77%。贮藏第7天，硬度进一步降低，但其他性状保持或增加。M1处理是加工鲜切苹果和获得改善的健康性状的合适选择。

期刊介绍： La Revista Facultad Nacional de Agronomía Medellín (RFNA), de la Universidad Nacional de Colombia, Sede Medellín, Facultad de Ciencias Agrarias, es una publicación científica editada desde el año 1939, en formato impreso y digital y de acceso abierto desde la web —sin costo para autores y lectores—. Está orientada a investigadores que crean conocimiento disciplinar y multidisciplinar que articula la ciencia y la tecnología para hacer más productivo el campo a nivel empresarial y de economía campesina. La Revista tiene como objetivo divulgar resultados de investigación mediante artículos originales, inéditos y arbitrados (peer review) de carácter científico que respondan a preguntas específicas y que proporcionen sustento y pruebas a una hipótesis, en aspectos relacionados con las Ciencias Agronómicas, Producción animal, Ciencias Forestales, Ingeniería Agrícola, de Alimentos y otras afines que contribuyan a la solución de los limitantes del agro a nivel nacional, regional e internacional. La Revista recibe y publica, sin ningún costo, artículos en idioma inglés de investigación, revisión, reseñas y cartas al editor. Desde el 2017 la periodicidad de publicación es cuatrimestral, se publican tres números al año con circulación nacional e internacional, en los siguientes períodos: Enero - Abril Mayo - Agosto Septiembre - Diciembre This journal does not charge APCs or submission charges.
