Descripción

General description

Meat extract is prepared from selected animal tissues that are free from fat and sinew. It is digested by weak proteolysis with pancreatin (porcine origin) before being extracted. In culture media, meat extract is usually employed in concentrations of 0.3 to 1.0%.

Application

Meat Extract is used as a nutritive substrate in microbial culture media. It is particularly suitable for cultivating lactic acid bacteria.

Features and Benefits

Our Granulated media are:

• Safer - Significant reduction of inhalation of toxic and allergenic substances resulting in fewer allergic responses. Less contamination of working tools and environment.
• Accurate - No separation of components and no clumping, even under humid or warm conditions, ensure a uniform product with higher performance accuracy.
• Fast - Rapid and uniform dissolution in water.
• Easier - Easier handling and weighing due to the better flow properties. Media do not stick to the flask or container.
• Reliable - Homogenous distribution of ingredients guarantees high reproducibility even if only small amounts of media are used.
