224 views

Rennet is traditionally made from the lining of calf stomachs, but most commercial rennet today is produced through fermentation processes involving microbes genetically modified to produce chymosin, the active enzyme in rennet. This microbial rennet is vegetarian-friendly and more consistent in quality, making it widely preferred in cheese production. It allows for greater efficiency and sustainability in cheese manufacturing, meeting the needs of various dietary preferences.

FAQs & Answers

  1. What is rennet and why is it used in cheese making? Rennet is an enzyme, primarily chymosin, that helps coagulate milk, turning it into curds and whey during cheese production. It is essential for the texture and formation of many types of cheese.
  2. How does microbial rennet differ from traditional rennet? Microbial rennet is produced by genetically modified microbes through fermentation, making it vegetarian-friendly and more consistent, whereas traditional rennet is extracted from the stomach lining of calves.
  3. Is microbial rennet safe and sustainable? Yes, microbial rennet is widely regarded as safe and offers sustainability benefits by reducing reliance on animal sources and enhancing cheese manufacturing efficiency.
