Mesoporous chitosan microspheres/gelatin-based food packaging film for modified atmosphere preservation of bayberries
摘要
Abstract
Bayberry is a kind of respiratory leap type fruit with unique flavor and high nutritional value.Due to its highly susceptible spoilage and the resulting economic loss,the preservation of bayberries has become the focus of food engineering research.Modified atmosphere packaging(MAP),as the most promising freshness preservation technology,can inhibit the respiration of fruits and vegetables by adjusting gas component(O2,CO2)concentrations inside the package.Inspired by the stomata of natural leaves,herein,polyethyleneimine(PEI)-modified mesoporous chitosan microspheres(particle size,39.8 μm)were innovatively introduced into tannic acid(TA)-gelatin films to prepare mesoporous microspheres/gelatin-based packaging films for modified atmosphere preservation of fruit.Subsequently,the stomatal-like structure of mesoporous microspheres was investigated,along with the microstructure,mechanical,optical,antioxidant and gas selective properties of gelatin-based films.Importantly,their preservation effects for fruits were also evaluated.As a result,PEI-modified mesoporous microspheres were successfully introduced into TA-gelatin film,and the prepared mesoporous microsphere/gelatin-based composite films showed excellent microstructure,mechanical properties(Young's modulus,1 031.4 MPa)and water resistance(contact angle,68.4°),which proved to be suitable for fruit packaging use.Moreover,mesoporous microspheres improved the CO2 selective transmittance(CO2/O2 selectivity,2.18)and antioxidation properties(ABTS clearance rate,99.8%;DPPH clearance rate,82.3%),and the films could effectively prevent the oxidative damage and delay the deterioration time by 5 times.This work provides new ideas for gelatin-based modified atmosphere preservation packaging(gelatin-based MAP)materials with gas selectivity and antioxidation activity.关键词
