Abstract: Thes tability ofc arotenoidsw ass tudiedi nt hisr esearch.T her esultss howedt hath igh temperaturea ffectst hes tability of carotenoids and carotenoids are sensitive to sunlight and UV. However, it is not so sensitive to lamplight. Carotenoids are more stable in alkaline condition compared to acid condition; The stability of carotenoids is reduced when Fe3+, Fe2+, Cu2+, Al3+ is respective added to its medium whereas other metal ions have no such effect on its stability. Oxidants and sour taste agent have destructive effect onc arotenoidsa ndr educing agents andp reservative havep rotectivee ffects.
