Liapse enzyme in milk?

Does anyone have experience with scalding your milk to remove the bad taste of extra liapse? My 10w son is primarily bf and was taking a bottle of my milk fine since week 1. We were doing a bottle every other day just to keep the momentum since my older two were difficult to take to the bottle. Now at 10w he will drink a bit of it then refuse it and it makes me wonder if I’ve got too much of the liapse enzyme. I’m not sure if this is something that can just change in breastmilk but curious of other mom’s experience.
