Abstract:Using pumpkin seeds as a raw material，organic zinc-rich foods were prepared by germination to increase the seeds'nutritional value，and improve palatability，digestibility and bioavailability.The growth of pumpkin seed buds under different germination conditions and the enrichment and transformation of organic zinc were studied by zinc sulfate soaking culture.The optimum concentration of zinc sulfate was 0.15% and the optimum incubation time was 48 h，under these conditions，the germination rate reached 81% and bud length was 30.18 mm of pumpkin seed.Comparison of pumpkin seeds before and after germination showed a good linear relationship between zinc absorption by pumpkin seed and zinc concentration in the medium.The zinc content of pumpkin seeds obtained under these conditions was 191.68 mg/kg，crude fat content was 32.61%，and the moisture content was 19.34%.
