Application
Heart extract from bovine heart is used in the food and beverage industry for microbiological testing to ensure product safety and compliance with regulations.
General description
Heart extract, sourced from a bovine heart, is a high-quality biological extract, specifically formulated for use in microbiological culture media. It is processed into a fine, light powder, ensuring easy solubility and consistency for laboratory applications. The heart extract is rich in specific amino-nitrogen and total nitrogen content, essential for the growth and development of various microorganisms in culture media. It features an assay range of 10 % total nitrogen on a dry basis, and its low ash content, approximately 15.0 %, signifies its purity and suitability for precise microbiological work. The bovine heart extract serves as an invaluable component in the preparation of culture media used in food, beverage, and pharmaceutical microbiology. Its solubility profile results in a clear, slightly yellow to light brown solution, which does not interfere with the visual assessment of microbial growth.
Preparation Note
Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place.
