Collagen Stability against Heat

Question

Hi, may I know if collagen is stable against heat? Will it denature when subjected to UHT? Any clinical papers to support answer?

What would be the recommended dosage to be present in the final product to claim that the product contains collagen?

    The native collagen is heat-unstable due to its product nature. However, there are commercial collagen in the market such as hydrolysed collagen which can be incorporated into UHT beverages. Beverages containing hydrolyzed collagen is sterilized in UHT-sterilizer at 137° C (Kamcharov et al., 2016).

    According to Food Regulation 1985, there are no specific regulation on the recommended dosage level for the claim of collagen.

      Hi,

      May I please check, if the process is retort (120 deg. Celsius for 20mins), will the collagen still be stable?

      Thank you.

        By referring to Kamcharov et al. (2016), the beverage is sterilized in UHT condition at 137° C for 4.2 seconds with a shelf life of 12 months when stored at 25° C.

            Collagen breakdown is dependent on factors including temperature and time. High temperature and long period (about 20 minutes) of exposure to heat accelerate the collagen denaturation (Dumitriu & Popa, 2013).
