What is Gelatin Made Of?
David Garcia
Gelatin is an animal-derived protein used to create the elastic, chewy texture associated with many gummy candies. It is produced by partially breaking down collagen from animal skin, connective tissue, and bones, then purifying and drying the resulting protein.
In gummy production, gelatin is valued because it hydrates, dissolves, and forms a thermoreversible gel as the product cools. The exact texture depends on factors such as gelatin type, bloom strength, concentration, sugar system, solids, acidity, cooking conditions, and drying.
What Is Gelatin Made From?
Commercial gelatin is commonly produced from bovine or porcine raw materials. Fish gelatin is also available for specialized applications. The source matters for technical performance, sourcing requirements, religious certification, labeling, and customer expectations.
Although the raw material contains collagen, finished gelatin is not simply “ground-up collagen.” Manufacturers use controlled pretreatment, extraction, filtration, concentration, sterilization, drying, and milling steps to produce a purified functional ingredient.
How Is Gelatin Made?
The exact process varies by manufacturer, but commercial production generally includes:
- Raw-material preparation: cleaned animal skin, connective tissue, or bones are prepared for extraction.
- Pretreatment: acid or alkaline treatment helps prepare the collagen structure for conversion.
- Extraction: controlled hot-water extraction converts part of the collagen into soluble gelatin.
- Purification: the liquid is filtered and refined to remove unwanted solids and impurities.
- Concentration and sterilization: water is removed and the product is processed under controlled conditions.
- Drying and milling: the gelatin is dried into sheets, granules, or powder and standardized for sale.
What Is Bloom Strength?
Bloom strength is a common measure of gel firmness. Higher-bloom gelatin generally forms a stronger gel at the same concentration, but bloom strength is only one variable in a gummy formula. Viscosity, process temperature, pH, solids, and the amount of gelatin used also affect the finished texture.
Commercial formulators should follow the specification sheet for the exact gelatin rather than substituting solely by weight between different bloom strengths.
Common Types of Gelatin
- Bovine gelatin: produced from cattle-derived raw materials.
- Porcine gelatin: produced from pig-derived raw materials and widely used in confectionery.
- Fish gelatin: produced from fish skin or other fish-derived collagen sources and used in selected applications.
- Sheet gelatin: gelatin formed into standardized leaves or sheets, more common in culinary applications.
- Powdered gelatin: the most common format for many commercial gummy formulas because it is easy to weigh and disperse.
Is Gelatin Vegetarian or Vegan?
No. Gelatin is animal-derived, so it is not vegan and is generally not considered vegetarian. Plant-based gelling systems such as pectin, agar, and carrageenan behave differently and cannot always be substituted one-for-one.
For the main confectionery comparison, see pectin vs. gelatin gummies. Plant-based gelling systems behave differently from gelatin, so any substitute should be validated as its own formulation rather than treated as a one-for-one replacement.
What About Kosher and Halal Gelatin?
Religious suitability depends on the animal source, slaughter method where applicable, processing, and the standards of the certifying organization. Buyers should verify the certification for the specific ingredient rather than relying only on a generic “kosher gelatin” or “halal gelatin” description.
Why Does Gelatin Need to Bloom?
Blooming allows dry gelatin to absorb water before heating. This helps the particles hydrate evenly and reduces the risk of dry clumps or uneven dissolution.
The correct hydration ratio and time depend on the gelatin and the formula. Commercial producers should follow the supplier's technical guidance or a validated recipe instead of assuming one universal water-to-gelatin ratio.

How Gelatin Works in Gummies
Gelatin gummies are made by hydrating and dissolving gelatin, combining it with the cooked syrup system, depositing the mass into molds, allowing the gel network to form, and then curing or drying the gummies to the target texture and water activity.
Process control matters. Excessive heat exposure can reduce gel strength, while incorrect acidity, solids, or drying conditions can cause texture problems. If a batch is failing to set, see why gummies won't set. For post-depositing texture development, see gummy curing vs. drying.
Gelatin vs. Pectin for Commercial Gummies
Gelatin typically produces a more elastic, chewy bite. Pectin gummies tend to have a shorter, cleaner bite and are suitable for plant-based products when formulated correctly. The manufacturing process is also different: pectin systems are generally more sensitive to the timing of acid addition, soluble solids, and pH.
If you are developing a production formula, Gummy Molds offers separate gelatin gummy recipe and pectin gummy recipe development products.
Does Gelatin Expire?
Dry gelatin is relatively shelf-stable when stored according to the supplier's instructions, but it can absorb moisture and odors. Commercial users should follow the manufacturer's lot-specific shelf life, storage temperature, humidity guidance, and packaging instructions.
Key Takeaways
- Gelatin is a purified protein produced from collagen-rich animal tissues.
- Bovine, porcine, and fish gelatins can differ in sourcing and performance.
- Bloom strength helps describe gel firmness but does not determine gummy texture by itself.
- Gelatin must be hydrated and dissolved correctly for consistent production.
- Plant-based gelling agents require their own formulations and process controls rather than simple one-for-one substitution.
