Muffin was developed using blueberry powder and the shelf life of the muffin packaged in modified atmosphere was determined. Blueberry was freeze-dried and milled to prepare powder. As the concentration of blueberry powder increased from 0 to 15% (w/w), hardness and gumminess also increased (p<0.05). The Hunter L and b values of the crust and crumb of muffin decreased as the concentration increased, while their Hunter a values increased. Blueberry powder concentrations of 10 and 15% resulted in high preference in taste, texture, and overall acceptability. Blueberry muffin containing powder at 10% was packaged in modified atmosphere (MA). The optimum gas for modified atmosphere packaging (MAP) of the muffin was the mixture of carbon dioxide (CO2) and nitrogen (N2) (7:3), which improved microbial stability without altering muffin hardness. The shelf life of modified atmosphere packaged blueberry muffin was determined using the accelerated life test. The shelf life values for MA packaged blueberry muffin stored at 25 and 35°C were predicted as 21 and 5 d, respectively. Further, the Q10 values for 25- 35°C and 35-45°C were determined as 4.2 and 2.9, respectively. The MAP can preserve blueberry muffin for 3 weeks at 25°C, without the external addition of preservatives.
