How Different Types of Gelatin Are Used in Gummy Production？
Gelatin is a key ingredient in the production of gummies, providing the chewy texture and structure that is characteristic of these candies. Different types of gelatin can be used depending on the desired properties of the final product. Here’s how various types of gelatin are utilized in gummy production:
- Type A Gelatin
Source: Derived from acid-cured tissue, typically pork skin.
Properties: Type A gelatin has a slightly different amino acid profile compared to Type B, which can affect its gelling and melting points.
Use in Gummies: Often used in gummies that require a softer, more tender chew. It’s also preferred in formulations where a lower melting point is desirable, making the gummies melt more easily in the mouth.
- Type B Gelatin
Source: Derived from alkali-cured tissue, typically beef bones or hides.
Properties: Type B gelatin has a higher gel strength and a higher melting point compared to Type A.
Use in Gummies: Ideal for gummies that need a firmer texture and a more robust structure. It’s often used in gummy bears and other shapes that need to maintain their form during handling and packaging.
- High Bloom Gelatin
Bloom Strength: High Bloom gelatin (typically 250-300 Bloom) has a high gel strength, meaning it forms a very firm gel.
Use in Gummies: Used in gummies that require a very firm and chewy texture. High Bloom gelatin is often used in premium gummy products where a strong, resilient chew is desired.
- Low Bloom Gelatin
Bloom Strength: Low Bloom gelatin (typically 50-125 Bloom) has a lower gel strength, resulting in a softer gel.
Use in Gummies: Suitable for gummies that need a softer, more delicate texture. It’s often used in gummy products aimed at children or in formulations where a melt-in-the-mouth quality is preferred.
- Fish Gelatin
Source: Derived from fish skin or bones.
Properties: Fish gelatin has a different amino acid profile compared to mammalian gelatin, which can affect its gelling properties. It typically has a lower melting point.
Use in Gummies: Often used in halal or kosher gummy products, or in formulations where a lower melting point is desired. Fish gelatin is also a good alternative for those avoiding mammalian products.
- Vegetable-Based Gelatin Alternatives (e.g., Agar-Agar, Pectin)
Source: Derived from plant sources like seaweed (agar-agar) or fruit (pectin).
Properties: These alternatives have different gelling properties compared to animal-based gelatin. Agar-agar, for example, forms a firmer gel, while pectin can create a softer, more jelly-like texture.
Use in Gummies: Used in vegetarian or vegan gummy products. Pectin is commonly used in fruit-based gummies, while agar-agar is used in gummies that require a firmer, more brittle texture.
- Hydrolyzed Gelatin (Gelatin Hydrolysate)
Properties: Hydrolyzed gelatin is partially broken down, resulting in a lower molecular weight. It has reduced gelling properties but can still provide some texture and mouthfeel.
Use in Gummies: Sometimes used in gummy formulations where a less chewy texture is desired, or in combination with other gelling agents to modify the texture.
- Custom Blends
Properties: Manufacturers often create custom blends of different types of gelatin to achieve specific textures, melting points, and mouthfeel.
Use in Gummies: Custom blends allow for precise control over the final product’s characteristics, enabling the creation of unique textures or specialized gummy products.
How to Make Gummies That Don't Melt？
To make gummies that don’t melt easily, focus on ingredients and techniques that enhance heat resistance. Start by using high Bloom gelatin (250-300 Bloom) or agar-agar, as they create firmer, more stable gels. Increase the gelatin concentration in the recipe for a stronger structure. Reduce moisture by cooking the mixture to a higher temperature (around 110°C or 230°F) in gummy cooking machines to evaporate excess water, which helps prevent melting. Stabilizers like gellan gum, modified starch, or carrageenan can also improve heat resistance and texture.
Sugar plays a key role—use a higher sugar content or replace some sugar with corn syrup, as it helps stabilize the gummies and reduces moisture sensitivity. Avoid excessive citric acid, as it can weaken the gel structure; use buffered forms or alternative acidulants like malic acid. After molding in gummy molding machines, allow the gummies to dry at room temperature for 24-48 hours to further reduce moisture and firm up the texture.
For added protection, consider coating the gummies with a thin layer of food-grade wax or shellac using gummy coating machines, which acts as a barrier against heat and humidity. These steps ensure the gummies maintain their shape and texture even in warmer conditions, making them suitable for high-quality production in gummy candy manufacturing lines.
