Lactose a (In the dry basis)/(g/100g) A lactose content according to (100- water-ash)/(100-water) calculation. 99.0
Water/(g/100g) 6.0 (GB 5009.3-2010 Karl fisher method)
Ash/(g/100g) 0.3 (GB 5009.4)
PH/(10% aqueous solution) Take 10g of lactose in 100ml beaker, add distilled water into 10% water solution,with a pH measuring the value of pH. 4.5-7.0.
Conclusion : The quality standard test of this food lactose is in accordance with the regulations.
