GELITA - How is Gelatine made?

Summary

This video delves into the intricate process of gelatin production, highlighting the transformation of collagen-rich pork belly into a versatile culinary ingredient. The journey begins with the extraction of collagen through a series of heating and acidification steps, followed by rigorous purification using advanced filtration techniques. The concentrated gelatin is then processed into noodles or powder, tailored to meet specific customer requirements. Additionally, the video showcases the production of leaf gelatin, emphasizing its uniformity for global culinary applications. Ultimately, gelatin enhances a variety of delectable dishes, demonstrating its significant role in the food industry.

Takeaways

• 😀 Gelatin is a tasteless, highly purified collagenous protein used in cooking and industrial applications.
• 📦 It comes in two forms: leaf gelatin, commonly used in home kitchens, and powdered gelatin, primarily for industrial use.
• 🔬 Gelatin production involves extracting collagen from animal skin, such as pork belly.
• 💧 The extraction process begins by chopping the rind into small pieces and soaking it in water mixed with vinegar to dissolve the collagen.
• 🌡️ Heating the mixture causes three layers to form: solids, an acid solution (the important layer), and fat.
• 🌀 Centrifugation is used to remove solid and fat components from the solution, isolating the collagen solution.
• 🚰 Filtration through fine ceramic microfilters is essential to eliminate turbidity and produce a clear gelatin solution.
• ⚗️ The purification process removes salts, and water is evaporated, resulting in a concentrated honey-like gelatin solution.
• 🧴 The concentrate is briefly heated for sterilization before being processed into noodles, dried, and milled into powder.
• 🌍 Gelatin is tailored to meet specific customer requirements, ensuring consistent quality for various culinary applications.

Q & A

What is gelatin primarily made from?

Gelatin is primarily made from collagen, which is extracted from sources such as pig skin.

How is the collagen extracted from the pig rind?

The pig rind is chopped into small pieces, soaked in water, and vinegar is added to dissolve the collagen. The mixture is then heated to aid extraction.

What are the three layers formed during the collagen extraction process?

The three layers are: a bottom layer of solids, a middle layer of the acid solution containing dissolved collagen, and a thin upper layer of fat.

What process is used to purify the collagen solution after extraction?

The collagen solution is filtered through ceramic microfilters to remove tiny particles and achieve a clear solution.

How are salts removed from the collagen solution?

Salts are removed by passing the collagen solution through synthetic resin beads, which adhere to the salts.

What happens during the concentration stage of gelatin production?

During concentration, the collagen solution is heated to evaporate water, resulting in a honey-like concentrate.

How is the final gelatin product processed before packaging?

The concentrate is heated to kill any remaining germs, then pressed into noodles, dried, chopped, and milled into powder.

What is the difference in production between powdered gelatin and leaf gelatin?

Powdered gelatin is processed into a powder, while leaf gelatin involves spreading gelatin mixture onto a cooling drum, cutting it into strips, and drying those strips into leaves.

What culinary uses does gelatin have?

Gelatin is used in various culinary applications, including making table jelly, chocolate mousse, and panna cotta.

Why is consistency important in the production of gelatin?

Consistency is important because customers require gelatin with specific properties, and each batch must be tailored to meet these exact specifications.
