Application of chitosan-incorporated LDPE film to sliced fresh red meats for shelf life extension Chitosan lactate was impregnated as an antimicrobial additive into low density polyethylene (LDPE) withdifferent concentrations. Also, these chitosan incorpo-rated films were applied on red meat surfaces to determine the effectiveness of chitosan on color shelf life extension and microbial growth inhibition. Chitosan was exposed to 0.1% peptone water containing the three pathogens in separate tests and inhibited microbial growth a higher levels with increasing con-centration of chitosan in the film matrix. Oxygen permeability was not affected by the incorporation ofchitosan, while the water vapor permeability increased with the addition of chitosan. Film elongationdecreased with the addition of chitosan. When chitosan incorporated films were applied on fresh redmeat, microorganisms on the meat surface were not inhibited but significant extension of red color shelflife were observed in refrigerated, sliced red meats. |

甲壳胺改性低密度聚乙烯薄膜在存放新鲜红肉片货架上的应用 延长使用寿命 甲壳胺乳酸通过不同浓度的抗菌添加剂浸渍后再改性低密度聚乙烯壳聚糖乳酸浸渍成低密度聚乙烯（LDPE）与不同浓度的抗菌添加剂。此外，这些甲壳胺掺入限制级可适用于食用红肉表面聚乙烯薄膜，这些壳聚糖具有延长有色货架寿命和抑制微生物生长的效果。壳聚糖暴露于含有三种病原体的0.1%蛋白胨水中进行单独测试，实验表明它可以抑制微生物的生长，提高薄膜基体中甲壳胺的浓度可以获得更好的抑制效果。 壳聚糖的纳入并没有影响透氧，而甲壳胺使得透湿效果额外增强。 甲壳胺除了薄膜伸长率下降外。在冷藏红肉切片观察中发现，使用甲壳胺改性薄膜的初期，肉表面上的微生物没有抑制作用，但红颜色保持时间显着延长。 仅供参考。  |
