Optimization of Extraction Technology of Medicinal and Nutrition Components from Rose

摘要

To tie with production needs of rose beverage, extraction conditions of roses were optimized. The indicators based on polyphenols, flavonoids, aqueous extract and amino acid content that in the leaching liquor. Researchers optimized factors including extraction temperature, solid-liquid ratio, extraction time and so on. The optimum extraction conditions were determined with orthogonal trial and researchers by composite score method. The results showed that extracts of polyphenols, flavonoids, and amino acid contents of water extract reached the maximum under such conditions: 100 V, solid-liquid ratio 1:50, and extraction 30min.
