• Gelatin is an ingredient widely used in the food, pharmaceutical and cosmetic industries.
Due to its unique gelling, stabilizing, and emulsifying properties, gelatin plays a key role in creating a variety of products, from delicate desserts to medicine capsules.
Gelatin is a protein derived from collagen, a natural substance found in the skin, bones and connective tissues of animals. It is obtained by prolonged boiling of these materials, a process that breaks down the collagen and extracts the gelatin, which is then processed into powder or sheets. Its color ranges from transparent to pale yellow, and its odor is neutral. Its defining property is its ability to form gels: it is soluble in hot water, insoluble in cold water, and solidifies upon cooling, creating a three-dimensional network that traps liquid and provides a firm but flexible texture.
Chemically, gelatin is neutral, but the pH of the medium (ideally between 4 and 8) influences gelation. Salts, sugars, or proteolytic enzymes (from fruits such as raw pineapple or papaya) can affect the texture of the gel. Specifically, sugars strengthen the gel to a point, but in excess can affect the texture, and proteolytic enzymes destroy the structure of the gel. Gelatin varies depending on the source – porcine, bovine, or marine – and its gelling power, measured in Bloom units (80-300 g). Plant-based alternatives, such as agar-agar or carrageenan, are used in vegan products, but have lower elasticity.
Various applications
Gelatin It is indispensable in many industries due to its properties as a gelling agent, stabilizer and thickener. In the food industry, it improves the texture and stability of products such as jellies, yogurts, sausages and soups. In the pharmaceutical and nutraceutical sector, it is used for capsules, due to its digestibility and bioavailability. In cosmetics, it contributes to the formulation of creams and masks, and in industrial applications it is used in adhesives.
In confectionery, gelatin is an essential ingredient for desserts such as panna cotta, Bavarian, mousses, jellies and layered cakes. It provides a smooth but stable texture, making it ideal for creamy or foamy preparations. For example, in mousses, gelatin maintains the aerated structure, and in jellies it creates an elastic consistency. In multi-layered desserts, it ensures the separation and cohesion of the layers.
The process involves hydrating the gelatin, dissolving it in hot liquid, and cooling it to solidify. The temperature must be controlled to avoid compromising gelation, and the pH of the preparation and ingredients such as sugar influence the result. Pork gelatin, which gels quickly, is preferred for firm jellies, while bovine gelatin, which has a lower gelation rate, is suitable for mousses and creams.
Proper hydration is essential for uniform gelling. The gelatin granules are sprinkled in cold water and left for a few minutes to swell, becoming gelatinous. Hot water should be avoided at this stage, as it can reduce the gelling power. After hydration, the gelatin is dissolved in warm liquid and integrated into recipes. For gelatin sheets, prior hydration ensures uniform dissolution, preventing lumps. This process protects the molecular structure of the gelatin, guaranteeing an effective gel.
In savory preparations, gelatin stabilizes aspics, risottos and terrines, providing a pleasant texture and aesthetic appearance. It controls humidity and stabilizes ingredients, being appreciated in the meat industry to improve the texture of sausages and in dairy for the creaminess of yogurts. To avoid excessive stiffening, the amount of gelatin must be carefully dosed, and ingredients with proteolytic enzymes (pineapple, papaya) must be heat-processed before mixing.
Types of gelatin and their uses
Pork gelatin is the most widely used in the food industry due to its neutral flavor and firm gels. Available in powder or sheet form, it has variable gelling power and is ideal for jellies, aspics and desserts that require rapid solidification. It requires careful hydration and dissolution to avoid lumps and maintain product clarity.
Bovine gelatin is a popular alternative, especially for those with allergies to pork gelatin. It gels more slowly, making it suitable for mousses and creams with an elastic texture. It is available in Kosher and Halal versions, meeting religious dietary requirements, and has similar applications to pork gelatin, but with subtle differences in flavor.
For vegetarians and vegans, there is the solution of vegetable gelatin, obtained from algae (agar-agar, carrageenan). Agar-agar forms firm but fragile gels at higher temperatures, making it ideal for concentrated jellies or cake layers. Carrageenan provides a softer texture. These alternatives require recipe adjustments because they lack the elasticity of animal gelatin.
Gelatin is a source of protein, containing amino acids such as glycine and proline, which support skin, joint and digestive health. It is low in calories, easily digestible and contributes to the feeling of satiety, being useful in diets. Although it is not a complete protein, it is a successful addition to a balanced diet. It is hypoallergenic, but may contain traces of allergens, and the source must be checked for Kosher, Halal or vegan diets, as plant-based alternatives have a different nutritional profile. Food regulations, monitored by authorities such as EFSA, ensure transparency and safety for consumers.
Gelatin market
According to a study by Persistence Market Research, the global gelatin market is expected to grow from USD 4,17 billion in 2025 to USD 6,54 billion in 2032, at a compound annual growth rate (CAGR) of 6,6%. The growth is supported by demand from the food industry, where gelatin is valued as a natural ingredient and "clean label", and from the pharmaceutical and nutraceutical sectors, for capsules and supplements.
Europe is a major production and consumption hub, with extensive applications in confectionery, dairy and meat, with the European Food Safety Authority (EFSA) ensuring strict quality standards. Emerging markets, particularly in Asia, are contributing to the expansion by rapidly adopting gelatine in new applications. And as the global market grows, driven by demand and innovation, gelatine, a natural ingredient with diverse applications in gastronomy and industry, is adapting to challenges such as sustainability and dietary preferences.
