中文摘要:

      可食性涂膜是一种由天然可食性材料制成的选择透过性薄膜, 具有调节果蔬内部气体交换、减少水分损失、降低腐烂率及延长货架期的特性, 在果蔬包装及保鲜领域中已引起广泛关注。鲜切果蔬具有新鲜、方便、快捷等特点, 已在全球范围内广泛供应餐饮业及零售业。可食性涂膜作为多种食品添加剂的载体常应用于生鲜产品中, 且将活性添加剂与可食性涂膜结合可以延长鲜切果蔬的货架期, 提高果蔬品质, 减少果蔬表面致腐及致病菌增长的风险。可食性活性涂膜将作为一种绿色、安全、营养的保鲜技术, 并将应用于鲜切果蔬保鲜领域的研究。本文综述了可食性涂膜的分类及其添加的抗菌剂、抗氧化剂、塑形剂、营养素等活性成分在鲜切果蔬保鲜中的应用, 旨在开发用于鲜切果蔬保鲜的功能性可食性涂膜。

英文摘要:

      Edible film is a kind of selectively permeable membrane which is made of natural edible material. It can coordinate the gas exchange, reduce the water loss and the rot rate, and prolong the shelf-life of fruits and vegetables. Edible coating film has gained a wide concern in the fields of food package and food storage. Fresh-cut fruits and vegetables had the characters of fresh, convenient, and rapid, which were widely applied in catering industry and retail industry. Edible coating as carrier of food adding agent were applied in fresh products. It incorporated with active adding agent that would prolong the shelf life, improve quality of fresh-cut fruits and vegetables, and reduce the increasing of pathogenic bacteria. Edible coating had been applied to preservation for fresh-cut fruits and vegetables as a kind of preservation technology of food safety. The application of edible coating classification and adding active ingredient of antimicrobial, antioxidant, nutrient on fresh-cut fruits and vegetables was reviewed in this paper. The purpose was to develop functional edible coating for preservation on fresh-cut fruits and vegetables.
