# What is a Gelatin made of?

**What is a Gelatin made of?: Collagen from animal skin and bone, broken down with acid or alkali and dried. There is no plant version.**

Gelatin melts at about 35 °C, just below body temperature, which no plant gum does — and that single property is why nothing substitutes cleanly. Agar and carrageenan set firmer and stay solid in the mouth; pectin sets only with acid and sugar. Fresh pineapple, kiwi, papaya, figs and ginger contain proteases that cut the collagen chains, so a jelly made with them never sets, though tinned fruit is fine because canning heat destroys the enzymes. Gelatin also appears well outside food: in capsule shells, in photographic film emulsion, and as a clarifier for wine and beer, which is why some drinks are not vegetarian.

## Component by component

*Every material is a choice, and the third column is the constraint that drove it.*

| Part | Material | Why that material |
| --- | --- | --- |
| raw material | pig skin, cattle hide and demineralised cattle bone | These are the cheapest concentrated sources of type I collagen, and are by-products of meat production rather than a separate industry. |
| process | acid pre-treatment (type A) or lime pre-treatment (type B), then hot water extraction | Acid suits soft pig skin and gives a gel that sets at a lower pH; lime suits tougher hide and bone and takes weeks. |
| gelling behaviour | triple-helix collagen fragments that re-associate on cooling | The helices re-form as the solution cools and hold water in a network — a physical set, so it can be melted and re-set repeatedly. |
| grade | bloom strength, roughly 50 to 300 | Bloom measures gel firmness; a recipe written for 200-bloom leaf gelatin fails with an unspecified powder of a different strength. |

## Common questions

### What is a Gelatin made of?

Collagen from animal skin and bone, broken down with acid or alkali and dried. There is no plant version.

### What is the raw material of a Gelatin made of?

Pig skin, cattle hide and demineralised cattle bone. These are the cheapest concentrated sources of type I collagen, and are by-products of meat production rather than a separate industry.

### What is the process of a Gelatin made of?

Acid pre-treatment (type A) or lime pre-treatment (type B), then hot water extraction. Acid suits soft pig skin and gives a gel that sets at a lower pH; lime suits tougher hide and bone and takes weeks.
