advances in food packaging

the ppt is all about the recent advances in food packaging

1. Advances in Food Packaging Madhavi Sharma Jv-u/13/6311 B.Tech(FT) VII Tri

2. What do you think packaging exactly is? It is simply enclosure of material under shield(i.e. packaging material). M eans of ensuring safe delivery of products to consumers. A rt, science or technology for preparing foods for transport, storage or sales away from the point of production. NOTE: packaging = silent salesman

3. Functions of food packaging Containment Protection Barrier Marketing C onvenience Communication Processing requirement Security

4. Recent packaging technologies/ Advances in food packaging E dible packaging Smart packaging Anti-microbial packaging Water soluble packaging Self cooling, self heating packaging Flavor and odour absorber M icro packaging

5. Edible Packaging T he food is generally packaged in edible material layers of other edible products. This step is beneficial so as to reduce the environmental pollution. The best thing about edible packaging is that it reduces the wastage of food and investment(money ).

6. Smart packaging This food packaging could tell consumers whether and when it's good or bad to eat. •   Indicate the quality of the product by changing color. Types A time-temperature indicator (TTI )- A device(super sensor) is attached to measure and display temperature. Freshness indicators - They signal directly product quality of the packed food with the help of devices like "electronic tongue”

7. Anti microbial packaging Antimicrobials in food packaging are used to enhance quality and safety by reducing surface contamination of processed food. Antimicrobials reduce the growth rate of microbes and acts against their growth. I n this type of packaging, the packaging surface is polished with some materials like silver ions chlorine dioxide, ethyl alcohol etc. which retards their growth.

8. Water soluble packaging It dissolves when comes in contact with hot water . Also called vanishing packaging R educes transport cost by shipping dry powders initially and then making final product when reached at destination. Easy to use. Reduces pollution Unique in the market place Mainly made up of PVA (poly vinyl alcohol)

9. Self cooling self heating packaging They can change the temperature according to the environmental requirements . Basically they contain some m echanical or chemical technology for such process. It is a type of active packaging used for beverages. T echnology adsorbs carbon dioxide from the atmosphere which is released when the  activation  button is pressed.

10. Flavor, Moisture and odor absorber Aroma water is being introduced which turns smell to flavor. Sometimes a small sachet is used to carry some harmless chemicals in it which can absorb odor and unwanted flavors from the food. Ethylene vinyl alcohol is generally used for such purpose . G enerally silica was used earlier.

11. Micro packaging This is introduced with the help of nanotechnology: Micro Packaging. The material, which is thousands of times thinner than human hair , is used for preparation of such film. T he packaging is significantly more eco-friendly than plastic. micro film consists of some proportions of soil, water and some special polymer. C lay nano-particles prevents oxygen, moisture and carbon dioxide from decomposing food products.
