Preparation and characterization of food antioxidaant active packaging films containing Quercetin loaded with mesoporous molecular sieve
摘要
Abstract
MCM-41 (Mobil Composition of Matter No.41)nanosilica mesoporous molecular sieves were prepared with cetyl trimethyl ammonium bromide (CTAB) and poly (ethylene glycol)-block-poly (propylene glycol)-block-poly (ethylene glycol)Mn～2900 (P131345)as a dual template,and further using MCM-41 as a carrier with natural quercetin antioxidant,low density polyethylene(LDPE) as a substrate to prepare a food anti-oxidation active packaging films.The product had a specific surface area of 439.173 m2/g,a pore volume of 0.665 cm3 g-1,and a pore size distribution of 2.4 and 4.0 nm.After the quercetin was adsorbed,the average clearance rates of DPPH free radical at 24 and 1200 h were 56.75％ and 66.01％.The diffusion rate of quercetin in the food simulants in active films prepared by quercetin adsorbed on mesoporous molecular sieve was lower than that of active quercetin films,decreased from 2.127 × 10-13 to 3.089 × 10-14.It showed that the anti-oxidation activity of food packaging prepared by using mesoporous molecular sieve as carrier would has anti-oxidant effect and sustained release.关键词
