dc.description.abstract | Recently, the Coolbot™ technology was introduced to smallholder farmers in Kenya as a low-cost alternative to
conventional cold rooms. The present study sought to establish the additive benefits of cold storage under
Coolbot™ cold storage and modified atmosphere packaging (MAP) in mango fruits. The participatory study was
conducted in Makueni County of Kenya between November 2014 and July 2015. The mango fruits (variety
„Apple mango‟) were harvested at mature green stage from commercial orchards owned by smallholder farmers.
The fruits were selected for uniformity and randomly separated into four batches which were subjected to four
different treatments (storage conditions). The treatments included fruits packaged using Activebag® MAP or not
packaged and either stored in the Coolbot cold room or at ambient room conditions. A random sample was taken
at regular intervals from each of the four storage environments and evaluated for ripening and quality related
changes during storage. The parameters evaluated included physiological weight loss, respiration, firmness, color,
sugars and vitamin C. Results showed that cold storage extended the shelf life of mango fruits by 23 days
without MAP and 28 days with MAP, in comparison to storage at ambient room conditions. Slow ripening under
cold storage (with and without MAP) was evidenced by lower rates of respiration, softening, color changes and
sugars accumulation compared to ambient room conditions. In addition, cold-stored mango fruits maintained
better nutritional quality as evidenced by higher vitamin C levels, 59.77 mg/100mL and 51.8 mg/100mL with
and without MAP respectively at the end of storage (day 40 and 35). This was significantly higher (p<0.05)
compared to 55.17 and 51.53 mg/100 mL vitamin C for MAP packed and unpacked fruits at the end of storage
under ambient room conditions (day 12). The results demonstrate the additive benefit of MAP and cold storage
to preserve postharvest quality and extend the shelf life of mango fruits. | en_US |
