Possible Interaction: Gelatin and Pectin

“More importantly, fluorescence and UV absorbance spectra, particle size distribution, and confocal microscopy results indicated that MTGase and pectin could change the structure of fish gelatin with the formation of large aggregates.”

“Our results showed that within a certain concentration, both MTGase and pectin had positive effects on the gelation point, melting point, gel strength, textural, and swelling properties of fish gelatin.”

“Cytocompatible formulations are obtained by combining pectin and gelatin at different ratios and using (3-glycidyloxypropyl)trimethoxysilane (GPTMS) as single crosslinking agent.”

“ Gelatin and Pectin , with rigid matrix and water interaction properties, decreased the swelling ratio.”

“Hydrogel particles were formed by mixing gelatin (0.5 wt%) with pectin (0 to 0.2 wt%) at pH values above the isoelectric point of the gelatin (pH 9, 30 °C).”

“We postulate that gelation was induced by a slow deesterification of pectin under conditions that would normally salt out (precipitate) low methoxy pectin in the absence of PME.”

“The high compatibility of gelatin with pectin or dextran in the ternary systems under given conditions is due to the formation of weakly bonded interpolymer complexes.”

“The observed phase separation is the result of incompatibility of gelatin with pectin , dextran molecules being distributed practically uniformly between coexisting phases.”

“A number of factors--pH, presence of other solutes, molecular size, degree of methoxylation, number and arrangement of side chains, and charge density on the molecule--influence the gelation of pectin.”

“The increase in heat stability of these gels is explained by the development of an ion lattice, which is due to the interaction of the oppositely charged groups of the pectin and the gelatin.”
