“…Intrinsic viscosity is a parameter that characterises the degree of space occupancy of the polymer (Evageliou, Ptitchkina, & Morris, 2005). It was obtained as the intercept of the Huggins and Kraemer plots.…”

“…In order to gain higher yield of pectin from pumpkin pulps, enzymic extraction was adopted and worth being commended [48,49]. However, The pumpkin pectin obtained by enzymic means did not form gels [50] and previous chemical modification is unsuccessful to improve this pectin preparation's gelling properties [51]. Further work need to continue toward two objectives: (1) search of righter enzymes for preparation of pectin samples; (2) development of methods for chemical modification of pumpkin pectin preparations with a view to improving their gelling properties.…”

Dietary plants and herbal preparations have been traditionally used as medicine in developing countries and obtained a resurgence of use in the United States and Europe. Research carried out in last few decades has validated several such claims of use of traditional medicine plants. Popularity of pumpkin in various systems of traditional medicine for several ailments (antidiabetic, antihypertensive, antitumor, immunomodulation, antibacterial, antihypercholesterolemia, intestinal antiparasitia, antiinflammation, antalgic) focused the investigators' attention on this plant. Considerable evidence from several epidemiological studies concerning bioactivities leads have stimulated a number of animal model, cell culture studies and clinical trials designed to test this pharmacological actions. In addition, it was found that technologies such as germination and fermentation could reduce antinutritional materials and affect the pharmacological activities of pumpkin. This review will focus on the main medicinal properties and technologies of pumpkin, and point out areas for future research to further elucidate mechanisms whereby this compound may reduce disease risk.

“…When pumpkin pectin was isolated by treating with several strains of Bacillus polymyxa , the yield was more than twice compared with mineral acid extraction (Matora and others 1995). Accordingly, much higher degree of acetyl esterification (DAE) was observed from the enzymatically extracted pumpkin pectin, which did not form gels as was the case for highly acetylated sugar beet pectin (Rolin 2002; Evageliou and others 2005). In order to improve the extraction yield of pumpkin pectin, various cell wall degrading enzymes, cellulase from Trichoderma viride , hemicellulase from Aspergillus niger , and a glycosidase complex from Xanthomonas campestris (Shkodina and others 1998) were utilized.…”
