BROOKFIELD TEXTURE ANALYZER

What is texture analysis?Texture analysis is primarily concerned with the evaluation of mechanical characteristics where a material is subjected to a controlled force from which a deformation curve of its response is generated. These mechanical characteristics in food can be further sub-divided into primary and secondary sensory characteristics which have proven to be correlated to sensory perception.

Brookfield now offers a complete bath system for processing gelatin samples in batches of 12 Bloom bottles. This system complies with GMIA and GME gelatin processing requirements, and the Brookfield Bloom bottles are recognized by both organizations.

Why measure texture?Consumer products succeed in the marketplace in part because their “textural characteristics” are pleasing to customers. This is certainly true with food products but it also applies to cosmetics, pharmaceuticals, packaging, industrial materials and even adhesive type materials.

Why Choose Brookfield?Brookfield Engineering is recognized around the world as offering high quality measurement instruments at an affordable price. Unsurpassed customer support is but one more reason to choose a Brookfield product when you are considering a viscometer, rheometer, texture analyzer or a powder flow tester.

The Brookfield Texture Department can also provide customers with complete texture assessment service. We specialize in the development of novel and innovative test applications and accessories for solid and semi-solid materials, enabling our customers to maximize the practical value of their texture studies within all test environments.

The CT3 Texture Analyzer utilizes uni-axial compression and tension forces in combination with a selection from our list of probes, grips and fixtures to test a wide variety of food, personal care products and industrial materials. Most tests desire to imitate conditions imposed on these products during manufacture, handling, and consumption or use. Characterizing the physical properties of your products in such an analytical manner provides “real life” insight and can be invaluable toward maintaining consistent, high quality manufacturing while minimizing cost.

Brookfield’s compact design of the CT3 has a long heritage of more than 20 years dating from the Stevens gelatin bloom tester. The CT3 still contains the Bloom test method and we offer the complete gelatin bath preparation system along with industry approved Bloom bottles.
