Health food (ready-mix) was prepared from maize and vegetables a source of lutein (L) and zeaxanthin (Z) and studied for its quality characteristics (moisture sorption isotherm, sensory,microbiological, chemical composition, and storage stability) on storage at varying temperatures for 3 months and L+Z bioavailability in mice. Results revealed a decrease in the L+Z level (4.70, 9.24, and 13.85%) of ready-mix stored at 4, 27, and 37◦C, respectively. Critical relative humidity and critical moisture content of the product was 64% and 12.24%, respectively. The product is well accepted and was not affected adversely during storage. L+Z bioavailability from ready-mix in mice was higher in plasma (29.4%), liver (58.7%), and eye (14.6%) than control (mice received diet with purified L). To conclude, L+Z in the ready-mix is stable and more bioavailable than control. These findings may help in understanding the importance of simple food processing to improve L bioavailability under its deficient condition among an elderly population.
