Bloom strength refers to the rigidity of the gel—essentially how "stiff" the jelly is. Viscosity, on the other hand, refers to the resistance of the liquid gelatin solution to flow. While they are related, Bloom is about the final set state, whereas viscosity is about the state of the product during mixing and processing. Both are critical for ensuring the correct texture and manufacturing efficiency.
Yes, but they require different specifications. Gummies usually need a high Bloom (200-300) for chewiness, while pharmaceutical hard capsules require an even higher Bloom and extreme purity to ensure the shell is thin yet strong and dissolves reliably in the stomach. Always check the COA (Certificate of Analysis) to ensure the grade matches the specific application.
Transparency is crucial for visual appeal. In clear jellies or beverages, any cloudiness in the gelatin can make the product look impure or low-quality. High-transmittance gelatin ensures that colors remain vibrant and the final product looks professional and appetizing to the consumer, which is why transmittance percentages are a key quality metric.
When stored in a cool, dry place in its original packaging (such as 25 kg kraft paper bags with PE liners), food grade gelatin typically has a shelf life of up to 36 months. It is important to avoid humidity and extreme temperatures, as these can lead to clumping or microbial growth, compromising the protein's functionality.
The choice depends on the desired "mouthfeel." For a soft, melting texture (like panna cotta), a lower Bloom (100-150) is ideal. For a firm, elastic texture (like gummy bears), a higher Bloom (200-300) is necessary. We recommend requesting samples of different grades to conduct a trial run in your production line.
Depending on the manufacturer and the customer's requirements, both sources are available. Many global suppliers, including Jinda, focus on selected bovine hides to provide a high-quality protein that meets a wider range of dietary and regulatory requirements across different global markets.
