Thermo-mechanical processing of sugar beet pulp. II. Thermal and rheological properties of thermoplastic SBP
Thermoplastic properties of extruded sugar beet pulp (SBP) are closely linked to water–polymer relationships. DSC analyses of water evaporation, water fusion and biopolymer relaxation according to SBP moisture content gave a more accurate estimation of SBP hydration steps than classical water adsorption isotherm. Three moisture contents (8%, 26%, 41% db) were then defined as limits of the diffe...
متن کاملpectin extraction from commercial cultivars of sugar beet pulp using the pre-hydrolysis technique
pectin is used as gelatinizing agent in food industry. in this study pectin was extracted from five commercial sugar beet varieties namely: doroty, rasul, 7112, br1 and ic using pre-hydrolysis technique. experiments were conducted using factorial design to verify the effect of temperature, time, percentage of hcl and water requirements on the extraction rate of pectin. the qualitative factors o...
متن کاملThermal Stabilization of Erwinia chrysanthemi pectin methylesterase a for application in a sugar beet pulp biorefinery.
Directed evolution approaches were used to construct a thermally stabilized variant of Erwinia chrysanthemi pectin methylesterase A. The final evolved enzyme has four amino acid substitutions that together confer a T(m) value that is approximately 11 degrees C greater than that of the wild-type enzyme, while maintaining near-wild-type kinetic properties. The specific activity, with saturating s...
متن کاملEffect of extraction conditions on the yield, purity and surface properties of sugar beet pulp pectin extracts
The extraction of pectins from sugar beet pulp was carried out in an aqueous acid medium under different conditions using a full twostate experimental design for three extraction parameters (pH, temperature and time). The yields of the extracted pectins ranged from 4.1% to 16.2%. Their contents in pectin constituents were 35.2–76.3% galacturonic acid, 6.8–32.9% neutral sugars, 2.0–4.2% methoxy ...
متن کاملPlant Pectin Methylesterase Treatments Dramatically Reduce Water-binding in Sugar Beet Pulp via Calcium Crosslinking
We are investigating a novel application of a thermally-tolerant plant pectin methylesterase (TTPME) to improve energy efficiency in sugar beet processing. Sucrose diffusion from cossettes occurs in water heated to about 70°C, the optimal temperature for TT-PME activity. Drying pulp is necessary to stabilize it for storage and commercialization as animal feed, but this consumes up to 30% of tot...
