摘要
This study investigated the effects of bubble or bubble gel characteristics on gas loading properties.The bubble carriers prepared by starch-fatty acid salt(SFAC)complex presented a better loading ability for ethylene with content in the range of 0.43-0.95 mL/g,in which bubble system prepared by 4%SFAC dispersion showed a better gas loading performance(0.95 mL/g).The gas content significantly decreased to 0.22-0.66 mL/g after bubble gel formation.However,all bubble gel had a slower gas release rate than that of corresponding bubble.In bubble gel system,bubble cavity immobilized with a gel network to reduce bubble breakage and coalescence,which was beneficial for retarding gas escaping.Besides,water layer surrounded by bubble cavity,as a physical barrier,could further slow gas-escaping speed.As an effective carrier,the bubble and bubble gel carriers based on starch are potential material for ethylene gas encapsulation used in fruit ripening applications.
