INTRODUCTION
• thermally processed food can undergo organoleptic changes and
cooked flavor accompanied by loss of vitamins, essential nutrients
and flavor.
• Increased consumers demand for safe, nutritious, fresh like food
with a high organoleptic qualities and an extended shelf life
resulted in the concept of preserving foods using non-thermal
techniques.
• Dense phase carbon dioxide (DPCD) process is also a non-thermal
process which is safe, inexpensive and preserve the nutritional
qualities of food materials.
WHAT IS DPCD PROCESS
• In this process food is contacted with pressurized sub or
supercritical carbon dioxide for a period of time in batch, semi-
continues or continuous system.
• Pressure varies from 7 to 40 MPa.
• Temperature varies from 20 to 60 ͦc.
• Time taken during the batch process is 120 to 140 min., and in semi
or continuous system it is 3 to 9 min.
• Temperature glide due to increase in pressure is negligible.
PAST DEVELOPMENTS
TYPES OF DPCD PROCESS
On the basis of flow there are three types of this
processes-
Batch type continuous type
Semi-continuous type

SEPARATION OF CARBON DIOXIDE FROM MIXTURE OF GASES
COMPARE WITH OTHER GASES
ADVANTAGES
• Gives fresh like food also after the storage with minimum energy
consumption.
• Elimination or reduction of heat damages to food.
• Improve the overall qualities of food materials.
• Low capital and operational cost.
• Waste free, environment friendly and energy efficient technology.
• Lower pressure and temperature required as compare to HPP.
Disadvantages
• False images of carbon dioxide.
• Low flow rate.
• Not possible at atmospheric conditions.
• Does not give complete inactivation of spoiled food product.
CONCLUSIONS
• This process is safe, economically adoptable, gives fresh like
food and retain the organoleptic properties of food materials.
• Till now it is not adopted by industries due to competitive
processes and also due to false image of carbon dioxide.
• Requires more research on this process.
• Also need to give attention toward the preservation of solid food
metarials.

Dense phase carbon dioxide processing (DPCD) for preservation of liquid food

  • 1. Presented by MAYA SHARMA Agricultural and food engineering department DENSE PHASE CARBON DIOXIDE PROCESSING FOR PRESERVATION OF LIQUID FOOD
  • 2. STRUCTURE OF PRESENTATION • Introduction • Past developments • What is dense phase carbon dioxide process • Types of this process • Mechanics of inactivation of microorganism • Effect on microbial cells and flavor • Brief about carbon dioxide • Advantages and disadvantages • Conclusions • reviews
  • 3. INTRODUCTION • thermally processed food can undergo organoleptic changes and cooked flavor accompanied by loss of vitamins, essential nutrients and flavor. • Increased consumers demand for safe, nutritious, fresh like food with a high organoleptic qualities and an extended shelf life resulted in the concept of preserving foods using non-thermal techniques. • Dense phase carbon dioxide (DPCD) process is also a non-thermal process which is safe, inexpensive and preserve the nutritional qualities of food materials.
  • 4. WHAT IS DPCD PROCESS • In this process food is contacted with pressurized sub or supercritical carbon dioxide for a period of time in batch, semi- continues or continuous system. • Pressure varies from 7 to 40 MPa. • Temperature varies from 20 to 60 ͦc. • Time taken during the batch process is 120 to 140 min., and in semi or continuous system it is 3 to 9 min. • Temperature glide due to increase in pressure is negligible.
  • 6. TYPES OF DPCD PROCESS On the basis of flow there are three types of this processes- Batch type continuous type Semi-continuous type

  • 14. EFFECT ON FLAVOR DURING STORAGE

  • 18. CURRENT SCENARIO OF ATMOSPHERIC CO₂
  • 19. SEPARATION OF CARBON DIOXIDE FROM MIXTURE OF GASES
  • 21. ADVANTAGES • Gives fresh like food also after the storage with minimum energy consumption. • Elimination or reduction of heat damages to food. • Improve the overall qualities of food materials. • Low capital and operational cost. • Waste free, environment friendly and energy efficient technology. • Lower pressure and temperature required as compare to HPP. Disadvantages • False images of carbon dioxide. • Low flow rate. • Not possible at atmospheric conditions. • Does not give complete inactivation of spoiled food product.
  • 22. CONCLUSIONS • This process is safe, economically adoptable, gives fresh like food and retain the organoleptic properties of food materials. • Till now it is not adopted by industries due to competitive processes and also due to false image of carbon dioxide. • Requires more research on this process. • Also need to give attention toward the preservation of solid food metarials.
