The main steps are below

- Take a representative sample and dry it. Homogenize and take 150 g to pulverize

- Homogenize the pulverized material and take 0.5 g

- Add 10 mL of distilled water in a 250 mL Erlenmeyer Flask. Add the 0.5 g, mix and add 50 mL og distilled water

- Heat and boil the system for 5 minutes. Remove tbe flask 

- When the flask is cold, add 50 mL of distilled water, mix the system and add 15 to 18 grams of sugar. The reaction take 15 minutes

- Add 4 to 5 drops of indicator. The titration agent is HCl

- Once the final is reached (the solution has not pink color), observe the mL of HCl added and use the formula
