Mannose to galactose ratios (III)
Variations difficult demonstration of E 412 presence in E 410/E 412 mixtures
Furthermore, man:gal ratios will be affected if other food additives (e.g., man from E 415)
Also, man and gal can be present in processed foods, thus affecting the man:gal ratios
Techniques are cumbersome and require complex extractions
Notes:
Methods based on the galactose to mannose ratio are further limited by other considerations. First, the food industry often use combinations of additives. So for example, the presence of additive E415 will affect the ratio due to the mannose of this addit
