Societal and industrial demands for lower environmental impact, cost effectiveness, and high‐performance goods and services are increasingly impacting the choice of technologies which are developed and deployed in consumer products. Like many other sectors, food packaging is moving to new technologies; the use of biopolymers is one of the most promising strategies toward an optimized use of traditional packaging materials (e.g., oil‐based plastics) without impairing the goal of extending shelf life. Among other food packaging materials, pullulan is attracting much attention due to its unique features. The goal of this review is to provide an overview of current and emerging applications of pullulan within the food packaging sector. In particular, the functional properties of interest for the food packaging industry will be discussed in light of the physicochemical attributes of this exopolysaccharide. Future challenges that may dictate the successful penetration of pullulan in the food packaging market are also outlined. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014 , 131, 40539. 相似文献

Conditions for maximal batch culture production of extracellular-L-rhamnosidase byAspergillus terreus have been investigated. Production of the enzyme appeared to be inducible by rhamnose and rutin, reaching a maximal level after an incubation period of 162 h when the fungus was grown at 37°C on either of these compounds as the carbon source and on ammonium phosphate as the nitrogen source. Nonionic surfactants did not enhance-L-rhamnosidase secretion. Under optimal conditions,A. terreus produced only one-L-rhamnosidase of approximate molecular weight 90 kDa (SDS-PAGE) and isoelectric point of 4.6. Onp-nitrophenyl--L-rhamnopyranoside as substrate, the enzyme showed pH and temperature optima of 6–8 and 45–50°C, respectively. Neither divalent cations nor ethylenediaminetetraacetate (EDTA) inhibited or stimulated enzyme activity. The enzyme was active at the concentrations of glucose found in must or of ethanol in wine. 相似文献
