Lasit fáddágilkoriid | Čoahkkáigeassu: | Blackberry (Rubus glaucus Benth) is one of the most perishable fruit due to its high level of respiration. This research aimed to evaluate the postharvest performance of blackberry by extending the shelf life of blackberry by adding an edible coating based on Aloe vera mucilage and propolis to extend the shelf life of blackberry, while maintaining the quality attributes and acceptability of fruit. It was used a factorial design (AxB), with two color indices and four coatings: (aloe vera 100%), (aloe vera + propolis), (water + propolis) and (plain water), the fruit were harvested at color indices (5 and 6), eight treatments were carried out of which T1 and T2 are water only. The variables to be measured in response to the test are: pH, soluble solids, firmness, moisture, weight loss, ash and incidence of pests and diseases (molds, fungi). The analysis of variance and Tukey's 5% significance test were performed for the indicators evaluated. The coating that showed the best performance was (water + propolis), which allowed maintaining the quality of the fruit because it helped to preserve the greatest amount of physicochemical properties such as: pH in T5 (water + propolis, in index 2) which obtained an average of 4.63 %, reaching the A range of significance, firmness in T5 (water + propolis, in index 1) which obtained an average of 0.42 kg/cm2, reaching the A range, for pest and disease incidence, treatment T5 (water + propolis, index 1) had a lower percentage of incidence with an average of 16% on the fourth day, 45.90% on the fifth day and an average of 93.3% on the sixth day of storage, reaching the A range. Blackberry with harvest index 2 (color 6) had the highest ash concentration, with an average of 9.42 %, reaching the A range of significance. It is concluded that the use of water plus propolis as an edible coating helps to conserve the physicochemical characteristics and to extend the shelf life of fruit. |
