How much lime juice to be used iso. citric acid?

AI Thread Summary
The discussion centers on substituting lime juice for citric acid in mozzarella cheese making. The original recipe calls for 1 1/4 teaspoons of citric acid per gallon of milk, but the user is unable to find citric acid and seeks guidance on how much lime juice to use instead. It is noted that the acidity level is crucial for curd stretching; too little acidity results in no stretch, while too much can ruin the curds. Participants emphasize that the acidity of lime juice varies based on factors like fruit ripeness, making precise conversions challenging. Suggestions include using general ranges for lime juice and considering the pH of the milk, which can significantly affect the outcome. The conversation also touches on the complexities of adjusting milk pH with citric acid, highlighting the importance of measuring tools like pH meters or strips for accurate results.

How much lime juice to be used iso. citric acid??

Dear all,
I'm now trying to make mozzarella cheese. The recipe wrote that use 1 1/4 tsp. for a gallon of milk (I think US gallon). The problem is I can't find citric acid right now. If I want to try lime juice instead of it, how much of lime juice do I have to use for 1 1/4 tsp. of citric acid??

FYI, acidity is what allows the curds to stretch: no acidity, no stretch but, too much acidity make curds become hopeless mess .

Thanks all.

Values that you can find (or that anyone can give you here) won't be accurate, as amount of citric acid present depends on the ripeness of the fruit and on many other factors. Best values should be given as "usually something between x and y".

If you can assume the value of the unknown parameters, can you show me how to solve the problem?

Or another question, If I want to reduce pH of 1 Litre of milk from X.x(I don't know pH of milk) to be around 5.6 by using citric acid (powder type) -- How many grams of citric acid do I have to use?? You can assume any parameter you want. Feel free to let me know things. Very thanks to you.:redface:

What do you know about the concentration and how it is related to volume of solution and amount of dissolved substance? Try to read concentration lectures, basically you will find everything you may need there - but feel free to ask if something is not clear.

Or another question, If I want to reduce pH of 1 Litre of milk from X.x(I don't know pH of milk) to be around 5.6 by using citric acid (powder type) -- How many grams of citric acid do I have to use?? You can assume any parameter you want.

There is no simple answer to that question - best approach is to use pH meter or pH strips. A lot depends on the initial pH (which can be already around 5.6 that you ask for).

Thank you Borek. I'll work it out and I may ask you later.:redface:

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
