Bio-degradable cassava starch-based adhesives were produced from chemically gelatinized starch formulations. The varying combinations of process parameters applied include: concentration gelatinization modifier, mass % borax/starch, and temperature reaction mixture. physico-chemical for characterizing the adhesive samples viscosity, density, pH bonding strength. effects variation on quality ass...

An important application of starch grafted with copolymers from unsaturated organic acids is the use as water absorbent. Although much research has been published in recent years, the kinetics of water absorption and the swelling behavior of starch based superabsorbents are relatively unexplored. Also, water retention under mechanical strain is usually not reported. Cassava starch was used sinc...

Collagen was extracted from the skin of pigs, and blended with sodium alginate, starch, and sodium carboxymethyl cellulose. Food packaging films were obtained by crosslinking the blend with glutaraldehyde. Fourier transform infrared spectroscopy (FT-IR), SEM and TGA analyses were used to characterize the resulting films. A strong hydrogen bonding was detected between the composite film molecule...

For starch digestion to glucose, two luminal a-amylases and four gut mucosal a-glucosidase subunits are employed. The aim of this research was to investigate, for the first time, direct digestion capability of individual mucosal a-glucosidases on cooked (gelatinized) starch. Gelatinized normal maize starch was digested with Nand C-terminal subunits of recombinant mammalian maltase-glucoamylase ...

The purpose of this study was to synthesize biomaterials from daily dental waste. Since alginate impression material contains silica and calcium salts, we aimed to synthesize calcium silicate cement from alginate impression material. Gypsum-based investment material was also investigated as control. X-ray diffraction analyses revealed that although firing the set gypsum-based and modified inves...

Alpha-amylase has a wide range of applications in starch industries, i.e. baking, brewing, distillery, etc. The alpha-amylase production from Streptomyces erumpens MTCC 7317 immobilized cells was compared with that of free cells. The immobilized cells of S. erumpens in calcium alginate beads were more effective for production of alpha-amylase (12.2% more yield) than free cells. Response surface...
