Bloom Tester

The Bloom Tester (Gel Strength Tester) is a precision instrument designed to measure gel strength, traditionally referred to as Bloom. It determines the force required to depress the surface of a gelatin gel by 4mm using a standard cylinder probe, ensuring consistent quality for applications in food, pharmaceuticals, and packaging.

Application of Bloom Tester

Why Gel Strength Measurement is Important?

Product Quality and Consistency: Bloom strength directly impacts product texture and usability, particularly in food and pharmaceutical products.
Regulatory Compliance: Compliance with standards like USP, ISO, and ASTM ensures product acceptance in global markets.
Cost Efficiency: Accurate testing minimizes waste by identifying optimal formulations and manufacturing conditions.

What is Bloom Strength – Working Principle

The Bloom Tester evaluates bloom strength of soft gelatin capsule based on a standardized procedure:

Gel Preparation: A gelatin gel is prepared under controlled conditions, typically at 10°C for 17 hours.
Probe Application: A 0.5-inch (12.7mm) diameter cylinder probe depresses the gel’s surface by 4mm.
Force Measurement: The force required to achieve this depression is recorded in grams and represents the gel’s Bloom strength.

This method provides repeatable results crucial for product consistency and quality assurance.
