Abstract
The lulo La Selva P32 is a cross over different kinds of lulo. Though its sensory characteristics improvement, its life span is very short. Due to it is a new kind of lulo, there are not so many studies over the ripening process. In order to understand some softening processes, in this work it is evaluated the xylanase kinetics at the lulo peel during ripening, and the results are correlated with the MRI (Magnetic Resonance Imaging) relaxation time T2. During ripening time, it is observed that the xylanase is one of the enzymes involved in the hydrolysis of the cell wall polymers. In addition, two T2 values regimes were distinguished by the xylanase kinetics. Although the correlation coefficient of 0.82 and p = 0.024 values, the results suggest that T2 weighted MRI can be useful as a non-invasive tool for ripening process monitoring.
Highlights
Colombia, due to its wide variety of climates, presents a lot of fruit crops, which are of interest for human consumption, both nationally and internationally, being the lulo one of them

Behavior of the xylanase during ripening of lullilo: After picking the fruits at their ripeness stage 1, we proceeded to the quantification of xylanase activity
Summary
Due to its wide variety of climates, presents a lot of fruit crops, which are of interest for human consumption, both nationally and internationally, being the lulo one of them. The lulo belongs to the Solanaceae family, considered to be tropical fruit grown at temperatures around 20 °C, at an altitude higher than 1000 m.a.s.l. The most popular varieties of lulo in Colombia are Solanum septentrional and Solanum quitoense; the latter called lulo "La Castilla" (CORPOICA 2011). In Colombia, lulo is grown in the departments of Antioquia, Cundinamarca, Cauca, Huila, Meta, Tolima, Valle, Caldas and Risaralda; being Huila the largest harvest area. In some regions, harvests have decreased due to phytosanitary problems, as well as the brief time of fruit ripening, which hinders commercialization and export.
