[Comparative evaluation of zinc organic and inorganic form bioavailability in vivo]
Abstract:
Bioavailability of zinc complex with enzymatic hydrolysate of milk protein (EHMP) was studied in Wistar rats. Body mass, zinc content in os femoris and serum alkaline phosphatase activity were similar in rats receiving Zn-EHMP and zinc sulphate and were significantly higher than in animals fed with basal semi synthetic zinc-deficient diet. Apparent absorption of both Zn sources in rat's intestine was high (more than 70%) probably due to absence of plant dietary fiber in applied diet. Zinc organic form use in fortification of food is discussed.
