GELITA - How is Gelatine made?

Introduction

This tutorial outlines the process of how gelatin is made, based on the informative video from GELITA AG. Gelatin is a versatile ingredient widely used in food, pharmaceuticals, and various technical applications. Understanding its production can provide insights into its uses and importance in different industries.

Step 1: Sourcing Raw Materials

• Gelatin is derived primarily from animal collagen, which is found in bones, skin, and connective tissues.
• Common sources include:
  • Pigskin
  • Bovine hides
  • Fish skins
• It is essential to source high-quality raw materials to ensure the resulting gelatin meets industry standards.

Step 2: Pre-Treatment of Raw Materials

• The raw materials undergo a cleaning process:
  • Remove impurities such as fat and meat residues.
  • Rinse thoroughly with water to ensure cleanliness.
• This step is crucial as it affects the purity and quality of the final gelatin product.

Step 3: Extraction Process

• The cleaned materials are soaked in a mild acid or alkali solution to facilitate collagen extraction.
• Key points during extraction:
  • The soaking time can vary based on the material and desired gelatin type.
  • Maintain appropriate temperature and pH levels to optimize collagen release.

Step 4: Concentration of Gelatin

• After extraction, the solution is concentrated through evaporation:
  • Heat the solution to remove excess water.
  • Be cautious not to overheat, as this can degrade gelatin quality.
• The concentration process results in a thick gelatin solution.

Step 5: Gelatin Drying

• The concentrated solution is then cooled and spread out to form sheets or granules.
• Drying methods include:
  • Air drying
  • Freeze drying
• The drying process reduces moisture content to ensure a stable product and extend shelf life.

Step 6: Milling and Packaging

• Once dried, the gelatin is milled into desired particle sizes.
• Packaging is done in moisture-proof materials to protect against humidity and contamination.
• Proper labeling is important for quality control and compliance with food safety standards.

Conclusion

Understanding the gelatin production process enhances appreciation for this essential ingredient. From sourcing raw materials to the final packaging, each step plays a vital role in ensuring high-quality gelatin. For those interested in utilizing gelatin in food or other applications, consider exploring various types and their specific properties.
