food packaging extensively uses plastic films and containers of petroleum-based polymers for their excellent functional properties and competitive price. plastic packaging has become a central focus of waste reduction efforts, particularly in aesthetic terms of damage to flora and fauna. presently, consumers require greater quality and longer shelf lives for their foodstuffs, while they demand ...
sorption of flavor compounds to inner layer of polymer packages and subsequent diffusion results in loss of food flavor and consequently decreases shelf life and consumer acceptance of food stuffs which in turn causes major economic losses, so it is of utmost importance to research on diffusivity of these compounds in polymers to minimize negative effects of this phenomenon. in current research...
This present study was elucidated the cytological effects of maize due to ageing (storage) in different packaging material. This study revealed that the cytological anomalies in somatic cells of maize inbreds (CM-138 and CM-142) due to storage in jute and plastic bags. For the cytological impact of storage, inbreds were stored in jute and plastic bags for different periods i.e. 4, 8 and 12 mont...
Fluorescent lamps are estimated to annually release 1 t of mercury into the air in the United States; transport of used lamps may play an important role in these emissions. In 1999, the U.S. Environmental Protection Agency added lamps to the universal waste rule to encourage recycling by allowing shipment to recycling facilities by common carrier. The rules required that lamp packaging must be ...
