KARAKTERISTIK FISIK EDIBLE FILM DARI TEPUNG PORANG (Amorphophallus oncophyllus)

Immunomodulatory Activity of Octenyl Succinic Anhydride Modified Porang (Amorphophallus oncophyllus) Glucomannan on Mouse Macrophage-Like J774.1 Cells and Mouse Primary Peritoneal Macrophages.

Porang is a local plant of Indonesia, which has a high content of glucomannan. In this study, porang glucomannan (PG) was esterified with octenyl succinic anhydride (OSA) to enhance emulsion properties to be widely used in food industry. OSA-modified PG (OSA-PG) enhanced the phagocytosis activity of macrophage-like J774.1 cells and mouse peritoneal macrophages. In addition, OSA-PG increased the...

Viscosity and Gel Formation of a Konjac Flour from Amorphophallus oncophyllus

The influences of different variables on the viscosity and gel formation of the konjac flour produced from Amorphophallus oncophyllus have been studied. At the concentration studied, the 1.5% konjac flour yielded a viscous solution than that of 0.5% konjac flour. The viscosity of konjac flour solution were unaffected by pH (pH 2 to pH 8), salt concentration (0-10% w/v), and high acid (pH 3.5) /...

Sequence Variation of CSLA Gene Responsible for the Synthesis of Glucomannan in Porang (Amorphophallus Muelleri Blume) Collected from Java, Indonesia

Porang (Amorphophallus muelleri Blume) collected from various geographical locations has been known to show variation on glucomannan content. Glucomannan is polysaccharide consisting hydrocoloid dglucose and d-mannose which has high economical value. One of the most important genes responsible for the synthesis of glucomannan is cellulose synthase-like A (CSLA) glycosyltransferase. From previou...

Euler-karakteristik for fusionskategorier

High molecular weight plant heteropolysaccharides stimulate fibroblasts but inhibit keratinocytes.

Konjac glucomannan (KGM) is a natural polysaccharide of β(1-4)-D-glucomannopyranosyl backbone of D-mannose and D-glucose derived from the tuber of Amorphophallus konjac C. Koch. KGM has been reported to have a wide range of activities including wound healing. In this study we examined KGM extracts prepared from five plant species, (Amorphophallus konjac Koch, Amorphophallus oncophyllus, Amorpho...
