- Preparation of reagent solutions (not supllied) :
- Trichloroacetic acid (50% w/v) : 100mL
- Hydrochloric acid (0.66M) : 1L
- Sodium hydroxide (0.75M) : 200mL
- Phytic acid :
- Sample extraction :
- Weigh 1g of sample material.
- Add 20mL of hydrochloric acid (0.66M).
- Cover with foil and incubate for a minimum of 3 hours at room temperature.
Add 50g of thrichloroacetic to 60mL of distilled water and dissolve. Make to volume (100mL) with distilled water. (Stable for > 6 moths at 4°C)
Add 54.5mL of hydrochloric acid to 945.5mL of distilled wtaer an mix. (Store at room temperature)
Add 6g of sodium hydroxide pellets to 180mL of distilled water and dissolve. Make to volume (200mL) with distilled water. (Store at room temperature)
Pure phytic acid control sample may be required.</u>
