Personally, I'd avoid using phosphate and excelerator.
But, anyway, can't answer the questions without knowing what type of ham and how you intend to cure it or age it (if that applies).
There are some situations where a cure excelerator should never be used.
About the ascorbic acid and nitrate, you should never combine ascorbic acid and nitrate anyway because they'll work against each other....ascorbic acid asks as a cure excelerator and nitrate is used in long term curing for a prolonged release of nitrite.
In addition to the questions above, what cure, specifically, will you be using?
About the phosphate, safe or not safe, there's no flavor in water!
Phosphate isn't needed if you practice good technique
I would also skip the Ascorbic acid, it's not needed in home curing.
I do use phosphates sometimes with good results, I sent you a pm with info and how to calculate the amount needed. if you need more info let me know.
[color= rgb(24, 24, 24)]I see your in Sri Lanka. You might want to check the % nitrite /nitrate in your cure. it could be much different then what we use in the states, and if you're using a recipe you found here you could end up under or over curing your loin. neither one would be a good thing.[/color]
