2. INTRODUCTION
ABSORPTION ADSORPTION SCAVENGING
Oxygen Scavengers and Their Role
Prevents Oxidation
Prevents Insect Damage
Prevents Proliferation of Molds &
Aerobic Bacteria

3. Oxygen Scavenger
SELECTION
Factors
affecting
the choice
1. Harmless
2. Absorption rate
3. Compact Size and quality
4. Economic Price
5. Not produce toxic substance
1. Oxygen level in headspace
2. Nature of food
3. Water activity
4. Desired shelf life of product

4. Conditions for O2 Scavenger
Packaging material with
high O2 barrier
Complete Heat Sealing
Ageless Eye
Redox Indicator
Total volume = A+B = (V-P)[O2]/100 + S*P*D
Appropriate Size & Type

5. Oxygen Scavenging Sachets
OXYGEN
SCAVENGING
TECHNOLOGIES
ARE BASED ON:
Ascorbic Acid Oxidation
Catechol Oxidation
Photosensitive Dye Oxidation
Enzymatic Oxidation
Unsaturated Fatty acids
Iron Powder Oxidation

6. O2 Scavenging Sachets
nn
For eg:
Ageless
Freshilizer
Enzyme OxidationIron powder oxidation Catechol oxidation
Catechol-organic compound
It passes metal detector.
For eg:
Tamotsu ( dry foods)
Glucose oxidase
and Catalase
reactions-
For eg:
Bioka
快节奏的工作
亚健康状态
Require small amount
of metal i.e. copper.
Ascorbic Acid Oxidation
For eg:
Oxysorb

7. OXYGEN SCAVENGERS
FILMS
Used for all products
O2 consuming substance -
polymer it self or
some oxidable
compound dissolved
in packaging
materials.
Problem-should not react
with atmospheric
oxygen before use.
Solution: By
1. Illumination
2. Catalysis
3. Reagents
Examples:
1. OS1000
2. Zero2
3. Oxyguard
LABELS
It is iron-based oxygen
scavenging label having
printable surface and it is
acceptable for food
contact.
It will remain in adhesion
to food package.
It is resistant to fat and
moisture.
Examples:
Freshmax-
Multisorb
Technology
BOTTLE
CLOSURES
Removal of oxygen
from bottle by
crowns, cans, plastic
and metal closures.
It is based on ascorbic
acid oxidation.
Examples:
Darex
Oxygen
Scavenging
Technology

8. Economic Aspects
• Increased shelf life
• Reduced distribution losses
• To save time and labor
• Reduced costs required for gas flushing
equipment's
• Increased length of time product can stay
in distribution line
