Jelly Bloom dosage

Jelly Bloom, or Bloom degree, is the standard unit of measurement used to evaluate the gelling strength of gelatin. It reflects the firmness of the gel obtained from a standardized gelatin solution and is an essential quality criterion in many industrial sectors: food (confectionery, dairy desserts, pastries), nutraceuticals (capsules, gummies), cosmetics (gel masks) and pharmaceuticals (soft capsules).

The dosage of Jelly Bloom allows you to:

• Characterize the texture and viscosity of gelatin according to its concentration.
• Select a quality of gelatin suitable for the technical requirements of the formulations.
• Verify compliance with supplier specifications or industry standards (GMIA, ISO 9665, Pharmacopoeias).
• To ensure the stability and reproducibility of gelling performance in finished products.

Principle of the titration method

The Bloom strength is measured by forming a gel under specific conditions (10% gelatin in water, 17–18 hours at 10 °C), then applying a vertical force using a standardized cylindrical probe (Bloom gelometer). The force (in grams) required to penetrate the probe 4 mm into the gel corresponds to the Bloom strength.

The higher the Bloom number, the firmer, more stable, and more viscous the gelatin's structure. Conversely, a low Bloom number indicates a soft texture and reduced gelling capacity.

Examples of beaches:

• 50 to 80 Bloom: low quality gelatin (animal feed, specialized nutrition)
• 150 to 220 Bloom: food standard (confectionery, dairy products)
• 250 to 300 Bloom: pharmaceutical or nutraceutical use (capsules, gel matrices)

Associated analytical techniques

In addition to traditional mechanical measurement, complementary methods can be used to characterize the purity and chemical properties of gelatin:

• UV-Vis spectrophotometry: nitrogen determination, detection of hydrolyzed proteins
• HPLC: identification of specific amino acids, monitoring of degradation
• Rheological measurements: study of viscoelastic behavior as a function of temperature or concentration

Matrices involved

• Raw or powdered gelatin
• Dietary supplements (capsules, gummies, chewable tablets)
• Jellied food products (desserts, sauces, jellies)
• Cosmetics (masks, hydrogel treatments)
• Functional texturizers for technical applications
