IZA, Fernanda; ROJAS-LEMA, Ximena y ARGUELLO, Yolanda. Quality baseline of the castilla blackberry (Rubus glaucus) in its food chain. Enfoque UTE [online]. 2016, vol.7, n.3, pp.82-94. ISSN 1390-6542. https://doi.org/10.29019/enfoqueute.v7n3.107.
A proposal for improvement in the performance of the food chain of castilla blackberry (Rubus glaucus) in order to potentiate their productivity can only start from a baseline or situational diagnosis of the quality of the fruit and hence identify the main points of improvement. The food chain of the fruit identifies three stages, harvest, post-harvest (storage and transport) and marketing or sale. The diagnosis in each stage began with reverse mode. It was identified the most representative producer and the supplying for traders to the point of sale. The quality evaluation of the fruit was performed through chemical and physical characterization in the four stages. Weight loss or losses were evident in all stages, light no significant changes of color from bright red bluish hue in the collection stage until opaque bluish red or off, at the stage of sale due to the short cycle time and the characteristics non-climacteric fruit. However, at all stages of collection, storage, transportation and sale, they presented significant changes in the indices of maturity which meant an increase of sugars, decreased of pH, and increase acidity. The results indicate that the fruit changed its physicochemical characteristics during the stages of the food chain affecting its productivity.
