Color issues in milk desserts

Hello ,
Please can you help me to find a solution for my problem related to milk color.
Dessert prepared from milk like rasmali etc is thermally processed ,after processing milk color change in to light pink …

@wara
Rasmalai should be white ( no additional color ) or yellow colored ( with saffron or turmeric).
If its rose colored there is some pink colorant maybe from.your impure rose water ,etc?:thinking:

Sir, No color added in it .
Before thermally processed it is white in color but after sterilization it changed color into light pink

@wara
Color pink is an odd color change for milk during heat treatment…pink color can only emanate from impurities present in your desert recipe …

Any preservative add in this like BHT to prevent this color changes in milk …

None …you should investigate where this odd color came from…
