The food packaging industries have got a problem of deterioration of sterilized food due to the attack of micro organism. This is due to the re-contamination of the food during packaging process. The recontamination after packaging can be avoided by sterilizing the packed foods. This will help to increase the shelf life of the food by killing the micro organism. Sterilization of the packed food...

118 Packaging is an indispensible vehicle to deliver products to consumers. The definition of packaging says that it is a co-ordinated system of enclosing food to protect it from tampering or contamination from physical, chemical and biological sources. Now a days consumer requires food that are fresh, mildly preserved, convenient and ready to serve. Per capita consumption of packaging material...

Reliable hermetic packaging of microelectromechanical system (MEMS) pressure sensor arrays for underwater applications always presents a formidable challenge, which is further compounded by the unforgiving harsh sea environments, during the design, fabrication and characterization stages of the sensor arrays. As such, a flexible underwater diaphragm-based pressure sensor array packaging scheme ...

The migration of packaging material constituents into food is a product of the interaction between the food and packaging material. This phenomenon is of importance because some migrating substances may be toxicologically carcinogenic and endanger the consumer safety. Polystyrenes are used in many food-contact applications for the packaging of aqueous-based, fatty and dry foods. The correlation...

Hydration of Ordinary Portland cement (OPC) in the presence of tartaric acid has been studied by using different techniques. Calorimetric studies have shown a rapid enhanced heat evolution within 5 min of hydration in presence of 1.0 wt% tartaric acid with a strong retardation of silicate phase hydration. DSC and X-ray diffraction studies have confirmed the formation of calcium tartarate hydrat...

Corrosion is one of the main causes affecting durability of structures. Corrosion effects on structures cannot be ignored and replaced. To understand the performance of structures there is a need to study the rate at which different corrosion levels occur. Hence the present investigation has been taken up to study the behaviour of NBS (National Bureau of Standard) beam specimens made up of Ordi...
