Optimization of Zinc enrichment process in snow pea sprouts
Using snow peas as the primary raw material,the content of zinc was determined using flame atomic absorption spectroscopy after drying. Based on single-factor experiments,orthogonal experiments were conducted to optimize and explore the best process conditions for zinc enrichment in sprouted snow peas. The results showed that the optimal conditions were:soaking time of 18 hours,sprouting temperature of 20 ℃,soaking temperature of 30 ℃,and zinc sulfate concentration of 100 mg/L. Under these conditions,the zinc content in snow pea sprouts reached 705.3746 mg/kg,which was 94.77 times higher than that of untreated sprouts. This research provides valuable technical support for the development of zinc-rich snow pea sprout technologies.
