The effect of packaging atmosphere, storage temperature, and time on the physical and chemical stability of Refractance Window® (RW)-dried mango powder was evaluated over a period of 12 months. RW-dried mango powder with a moisture content of 0.037?±?0.001?kg water/kg dry solids was stored at 5, 22 and 45°C for 12 months using air or nitrogen flush packaging. Headspace gas composition in the package, moisture content, color, ascorbic acid (AA), β-carotene, and microstructures of powder was measured at months 0, 6, and 12. The mango powder stored at 45°C suffered discoloration and ascorbic acid and β-carotene degradation after 6 and 12 months of storage in both air packaging and nitrogen flush packaging, while powder stored at 5 and 22°C had reduced nutrient degradation and preserved color of mango powder for both packaging conditions. Replacing the air inside the package with nitrogen was effective in preserving AA in mango powder stored at 22 and 5°C. Nitrogen flushing also reduced the percentage loss of β-carotene after 6 months, but no significant difference was found after 12 months. The microstructure of mango powder stored at 5 and 22°C was preserved after 6 and 12 months. Regardless of the packaging technique applied, the powder particles inside the package formed a single lump when stored at 45°C. The microstructures of mango powder at different storage conditions confirmed these results. Nitrogen flush packaging of mango powder is recommended to minimize degradation during long-term storage. 相似文献

Critical parameters in selecting the most appropriate packaging for soap and detergent products are reviewed. Included among
these parameters are package strategy, features required for consumer utilization, competitive products, cost limitations,
availability of materials having adequate chemical resistance to product, overall dimensions and construction details, machinability
of selected design, pallet pattern or shipping configuration, physical strength of individual package and outer case, ability
to withstand storage and handling rigors. Guidelines and criticality tests are reviwed briefly as tools for evaluating and
projecting the effect of a given parameter on acceptability of the finished package. 相似文献
