Effect of different packaging and cold storage on quality of blueberry
Blueberry fruits were packed into microporous membrane bag, 0.03mm polyethylene (PE) bag and modified atmosphere (MA) box and stored at 0°C for 50 days. The results showed that sensory evaluation, firmness, soluble solids content (SSC), titratable acidity (TA) and vitamin C (Vc) contents of blueberries decreased gradually, when the O2 and CO2 concentrations with MA storage reached 5-7%, 8-10%, respectively, the gas concentration keep the balance. The quality of blueberries in this condition were maintained the best quality. Its sensory evaluation, firmness, weight loss, the contents of soluble solid, vitamin C and titratable acidity of blueberry after 50 days storage were 3.4, 89.6 g, 6.75%, 10.4%, 19.81 mg 100 g-1 and 0.58%, respectively. MA storage can remain a high commercial value and extend the shelf life of blueberry.
