Optimization of resin decoloration technology of pectin polysaccharide from Passiflora edulis Sims by response surface methodology
摘要
Abstract
The resin decoloration conditions of pectin polysaccharide from Passiflora edulis Sims was optimized by response surface methodology.The polyamide resin decolorization was optimized by static adsorption method from six kinds of resins,then the effects of loading quantity of sample,volume flow rate,pH on decolorization rate,galacturonic acid retention rate was studied by single test.TheBox-Behnken was established to analyze the relationship between influening factors and decolorization rate,galacturonic acid retention rate of the polysaccharide respctively.The results showed that optimized conditions were sample loading was 3.5 BV,flow velocity was 3 BV/h,pH was 3.5.Under these conditions,a decolorization rate of 52.78％ and galacturonic acid retention rate of 85.62％ were obtained of which the actual values were 98.82％ and 98.19％ of the theoretical prediction values respectively.The method proposed in this study would provide a scientific base for further development and utilization of Passiflora edulis Sims source as well as functional food.关键词
