Study Notes
Hurdle Technology Overview
- Hurdle Technology is a food preservation method that uses a combination of preservatives, called hurdles, to inhibit the growth of microorganisms in food.
Development of Hurdle Technology
- The concept of Hurdle Technology was introduced by Dr. Lothar Leistner, a German scientist.
Purpose of Hurdle Technology
- The purpose of Hurdle Technology is to create an environment that is not favorable for microbial growth, thereby preserving food.
Application of Hurdle Technology
- Hurdles in Hurdle Technology should be 'high enough' to prevent microbial growth, but not so high that they affect the sensory characteristics of the food.
- Hurdle Technology is commonly used for high-moisture foods, such as meat, dairy, and seafood products, as well as for foods with high water activity.
Aims of Hurdle Technology
- Hurdle Technology aims to ensure the microbiological safety and stability of food products.
Selected Hurdles
- The selected hurdles in Hurdle Technology should be effective against a wide range of microorganisms, and should also be compatible with the food product.
Application of Hurdles
- Hurdles in Hurdle Technology are applied in combination, with each hurdle contributing to the overall preservation of the food product.
Principle Behind Hurdle Technology
- The principle behind Hurdle Technology is that by applying multiple hurdles, the growth of microorganisms can be effectively inhibited, ensuring the safety and stability of food products.
