Evaluation of carboxymethyl cellulose edible coating enriched with moringa leaf and seed extracts' performance on maintaining quality and shelf-life of avocado fruit
The performance of edible coating treatments composed of 2% moringa leaf (MLE) and seed extracts (MSE) in two levels of carboxymethyl cellulose (CMC) (0.5 and 1%) was investigated on maintaining postharvest quality of 'Fuerte' avocado fruit. Fruit quality measurements were taken on mass loss, firmness, and C-7 sugars during the postharvest storage period. The treatments had a significant effect on fruit quality. The MLE + 1% CMC treatment had a lower mass loss and maintained higher D-mannoptulose than the control fruit. The overall results showed the MLE + 1% CMC had the highest efficacy in fruit physical and biochemical quality aspects, followed by MSE + 1% CMC. In conclusion the study shows that moringa extracts irrespective of the tissue (leaves or seeds) used combined with CMC has an impact on postharvest quality of avocado.
