Abstract
Pectin or pectin-like polysaccharide (PLP) is a kind of complex polysaccharide in the plant cell walls, and consist on covalently linked galacturonic acid polymer as a backbone and neutral sugars chained on side parts. The functions of PLP are the substrates of gelling and stabilizing polymers in food industry. Furthermore, PLP has an important role in medicinal removal of heavy metals and anticancer activity reported to be beneficial for human health. The aim of this study was to extract, characterize and compare the PLPs isolated from Arthrospira (Spirulina) maxima and citrus peel as a control sample with different chemicals and methodologies. The yields of the extracted PLP isolated from A. maxima were 21.06±3.5% in distilled water (DW) and 24.48±1.2% in acidic condition (AC), whereas the yields of PLP from citrus peel of 8.68±1.2% (DW) and 9.37±0.6% (AC), respectively. The yields of galacturonic acid of PLP from A. maxima were 8.40±0.1% (DW) and 8.36±0.1% (AC). In biological activity tests, Fe2+ chelating activity was 26% higher than pectin from citrus peel. These results indicate possibility of medicinal application. we will be discussed in progress and further studies.are the substrates of gelling and stabilizing polymers in food industry.
