    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.
