Test Date: 14 June 2010
Tested materials: PrimePro® and regular plastic bags
Tested produce: Bananas (Cavendish and “Platano de Canarias” or Canarian banana)
To perform the study, the daily evolution of 28 samples was analyzed:
- Canarian banana: 7 bunches packed in normal film and 7 in PrimePro® film
- Cavendish banana: 7 bunches packed in normal film and 7 in PrimePro® film.
Temperature and humidity levels were adjusted to simulate conditions at a retail store. The average temperature was 22.5 ° C. Once the samples were packaged, the conditions, color, weight, temperature and relative humidity were measured at intervals of 24 hours during 6 days study.
COLOR: For both the Canarian and Cavendish bananas, color development was slower in the samples packaged with the PrimePro® film. Both types of banana packed in PrimePro® were approximately 0.5 – 1.0 “greener” on the banana colour scale than control samples of the same age.
WEIGHT: There was considerable difference in weight loss between bananas packed in normal film and ones in PrimePro® film. For the Canarian bananas, the weight loss 6 days after packaging with normal film was 38g, while the weight loss of fruit packed in PrimePro was 20g, which is 47% less. In the case of Cavendish bananas the difference was 26%.
