Advances in Food Packaging

What do you think packaging exactly is?

• It is simply enclosure of

material under shield(i.e. packaging

material).

• Means of ensuring safe delivery

of products to consumers.

• Art, science or technology for preparing foods for

transport, storage or sales away from the point of

production.

NOTE: packaging = silent salesman

Functions of food packaging

• Containment

• Protection

• Barrier

• Marketing

• Convenience

• Communication

• Processing requirement

• Security

Recent packaging technologies/ Advances in food packaging

• Edible packaging

•Smart packaging

• Anti-microbial packaging

• Water soluble packaging

• Self cooling, self heating packaging

• Flavor and odour absorber

• Micro packaging

Edible Packaging• The 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).

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

1. A time-temperature indicator (TTI)- A device(super

sensor) is attached to measure and display temperature.

2. Freshness indicators - They signal directly product

quality of the packed food with the help of devices like

"electronic tongue”

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.

• In this type of packaging, the packaging surface is polished

with some materials like silver ions chlorine dioxide, ethyl

alcohol etc. which retards their growth.

Water soluble packaging• It dissolves when comes in contact with hot water.

•Also called vanishing packaging

• Reduces 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)

Self cooling self heating packaging• They can change the temperature according to the

environmental requirements .

•Basically they contain some

mechanical or chemical technology

for such process.

• It is a type of active packaging used

for beverages.

• Technology adsorbs carbon dioxide from the atmosphere

which is released when the activation button is pressed.

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.

• Generally silica was used earlier.

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.

• The packaging is significantly more eco-friendly than plastic.

• micro film consists of some proportions of soil, water and

some special polymer.

• Clay nano-particles prevents oxygen, moisture and carbon

dioxide from decomposing food products.
