2.4. Storage of powder
The samples of MMP were separately packaged in tin, 4-ply laminates, polystyrene and metalized polystyrene and stored at 30±1 °C and 5±1 °C for storage studies. The mango pulps were stored with higher levels of sulfur dioxide [12]. With additional packing such as bag-in-box (a polyethylene pouch placed in a cardboard box) or the aluminium laminated high-density polyethylene, the loss of b-carotene can be further reduced.
Baneshan, Suvarnarekha varieties showed that the results of mango powders can be safely stored in metalized polyester/polyester poly packaging for a period of up to 6 months. For storage beyond 6 months additional packaging may be required [13].
