植酸(總磷)檢測試劑盒 Phytic Acid (Total Phosphorus) Assay Kit
植酸主要存在于植物的種子、根干和莖中,其中以豆科植物的種子、谷物的麩皮和胚芽中含量較高,植酸是谷物、部分豆類、油料種子中磷的主要貯存形式。
phytic acid 植酸,又名肌醇六磷酸,在食品工業中,植酸可用作食品添加劑,在釀酒工業中可用作除金屬劑。
Colourimetric method for the determination of Phytic Acid in cereal products, seed materials, animal feeds and other materials
Principle:
(phytase)
(1) Phytic acid + H2O → myo-Inositol (phosphate)n + P i
(alkaline phosphatase)
(2) myo-Inositol (phosphate)n + H2O → myo-inositol + Pi
(3) Pi + ammonium molybdate → 12-molybdophosphoric acid
(diaphorase)
(4) 12-molybdophosphoric acid + H2SO4 / ascorbic acid → molybdenum blue
