Understanding the different grades of gelatin is crucial for manufacturers across various industries, from food and pharmaceuticals to industrial applications. Gelatin grades, determined by factors such as source, purity, and gel strength, directly influence its suitability for specific uses. This guide provides a comprehensive overview of gelatin grades, their classifications, and how manufacturers can choose the right grade for their needs.
Gelatin grade refers to the classification standard of gelatin according to its source, purity, gel strength (usually expressed as Bloom value) and its application field. This grade can help determine the suitability of gelatin for specific applications, such as food, medicine, cosmetics or industrial use. Different grades usually reflect the physical and chemical properties of gelatin, such as gel strength, transparency, viscosity, etc., which in turn affect its use effect in specific products.
The grade of gelatin is mainly classified according to its source, purity, gel strength (usually expressed as Bloom value) and application field. Here are some common ways to classify gelatin:
Classification by source:
·Bone gelatin: extracted from animal bones, usually has a higher gel strength and is suitable for food and pharmaceutical fields.
·Skin gelatin: extracted from animal skin and widely used in food, medicine and cosmetic industries.
·Fish gelatin: extracted from fish skin or scales, suitable for applications that do not use mammalian products, such as halal food.
Classification by Bloom value:
·Low Bloom value (50-150 Bloom): usually used in soft foods such as soft candies and cakes.
·Medium Bloom value (150-220 Bloom): suitable for harder foods such as jelly and candy.
·High Bloom value (220-300 Bloom): used for products that require high gel strength, such as hard capsules, gel tablets, etc.
Classification by use:
·Food grade gelatin: used in food processing such as candy, jelly, yogurt, etc.
·Pharmaceutical grade gelatin: used for pharmaceutical capsules, drug coatings, etc.
·Industrial grade gelatin: used in non-food industries such as photographic film, coatings, and paper.
Classification by purity:
·High purity gelatin: used for applications requiring higher purity, such as medicine and biotechnology.
·Ordinary purity gelatin: suitable for general food processing and industrial applications.
The grade of gelatin depends on the specific application requirements. For example, food production usually requires food grade gelatin, while the pharmaceutical industry requires gelatin with higher purity and specific gel strength.
The source of gelatin (such as cattle bones, pig skin, fish skin) affects its chemical composition, gel strength and purity, and thus the grade of gelatin.
Different extraction and processing methods (acid, alkaline or enzyme) affect the molecular structure and physical properties of gelatin.
This is a measure of the gel strength of gelatin, usually between 50 and 300 Bloom. Higher Bloom values indicate stronger gel strength and are suitable for products that require harder or more elastic products.
Lower ash content generally means higher purity, especially in pharmaceutical and high-end food applications, purity is an important factor in determining gelatin grade.
The protein content in gelatin and its structural integrity also affect its quality and grade.
High-grade gelatin is usually lighter and more transparent, suitable for products that need to maintain visual and sensory properties, such as food and cosmetics. The higher the transparency of gelatin, the higher the grade, especially in applications that require a transparent appearance, such as capsules or jellies.
The viscosity of gelatin in solution affects how it performs in various applications. Different grades of gelatin will exhibit different viscosities at the same concentration.
Excessive moisture content will reduce the quality of gelatin, so gelatin with lower moisture content is usually higher grade.
Microbiological indicators:
Gelatin with low microbial content is often used in applications that require high safety standards, such as the pharmaceutical and food industries.
These factors together determine the final grade of gelatin, affecting its suitability for use in different fields and products.
Pharmaceutical grade gelatin requires extremely high purity and safety, and meets strict pharmacopoeia standards, such as the United States Pharmacopoeia (USP) or the European Pharmacopoeia (EP). At the same time, good manufacturing practices (GMP) must be followed during the production process to avoid contamination and ensure product quality consistency. The main applications of pharmaceutical grade gelatin:
·Pharmaceutical capsules: Pharmaceutical grade gelatin is widely used in the manufacture of pharmaceutical capsules because its excellent solubility and stability can ensure the effective release of drugs.
·Pharmaceutical gelatin: It is used to make various pharmaceutical gels, such as topical ointments and dressings, to improve the stability and bioavailability of drugs.
·Supplements: As the base material for capsules or tablets, pharmaceutical grade gelatin is often used in dietary supplements to provide necessary nutritional support.

Food-grade gelatin must comply with food safety standards to ensure that it is safe to use in food and does not contain harmful substances. The production process must comply with food production specifications to avoid any risk of affecting food safety. Main applications of food-grade gelatin:
·Food processing: Widely used in various food processing, including candy, jelly, pudding and ice cream, to provide gelling and thickening effects.
·Beverage industry: Used as a clarifier in beverages to help remove impurities and improve the appearance of the product.
·Baked products: Used as a thickener and stabilizer in some baked products to improve the texture and taste of the product.

Industrial-grade gelatin is mainly used in industrial production and is required to meet specific industrial standards rather than food or drug standards. Compared with pharmaceutical and food-grade gelatin, its purity requirements are relatively low, but basic product performance must still be guaranteed. Main applications are
·Papermaking industry: Used for coating and surface treatment of paper to improve the strength and gloss of paper.
·Photographic industry: In traditional photography, it is used to make the photosensitive layer of film and photographic paper.
Custom-grade gelatin is tailored to the specific needs of customers to meet the performance requirements of specific applications. Special-grade gelatin is designed and produced for specific industries or applications (such as medical devices, special food products). Main applications:
·Medical devices: Making specific components in medical devices, such as degradable medical implants and biomaterials.
·High-end food: Used in high-end catering and food products to provide special texture and flavor.
·Technical applications: Used in the technology industry to manufacture high-performance materials and products, such as bio-printing and material science applications.
These different grades of gelatin meet the special needs of their respective fields, and through strict quality control and customized production, they ensure the performance and safety of the products in their respective applications.
First, determine the application requirements. Based on the different gelatin grades and their applications above, determine the gelatin requirements for the application area. At the same time, consider the functional requirements of gelatin, such as:
