How to Measure Bloom Strength of Agar-Agar Using the Bloom Test
Introduction to Agar-Agar and Its Industrial Relevance Agar-agar is a natural hydrocolloid extracted from red algae, widely used in food, pharmaceutical, microbiological, and cosmetic applications. Known for its excellent gelling and stabilizing properties, agar-agar must meet strict quality standards, particularly in terms of gel strength, to ensure consistent performance across production batches. One of the most standardized and widely recognized methods to measure gel strength is the Bloom test. What Is the Bloom Test? The Bloom test is a universally accepted method used to assess the Bloom strength, or gel firmness, of hydrocolloids such as agar-agar and gelatin. It involves penetrating a gel sample with a standardized plunger under controlled […]
