Table 1.

The solubility of mechanochemically prepared lutein and zeaxanthin complexes with AG and GA disodium and ammonium salts in water (in mg/l), measured by HPLC after paper filtration.

Sample	Free	AG	GA-NH₃	GA-Na₂
Lutein 1:20	0.01^*	18	15	10
Lutein 1:40		10
Zeaxanthin 1:20	0.01^*	21	9	2.8
Zeaxanthin 1:40		8

This approximate value may be an upper limit due to penetration of small carotenoid crystals through paper filter.
