In recent years, microporous modified atmosphere packaging has been widely concerned because of its adjustable air permeability and low processing cost. With the development and increasing demand of fresh food industry, the limited permeability of film in modified atmosphere packaging can't meet the fresh-keeping requirements of fresh foods, especially vegetables and fruits. Microporous film can flexibly adjust the gas permeability according to the physiological metabolic characteristics of fresh foods, which has gradually become a fresh-keeping technology in the domain of vegetables and fruits. This paper reviewed the research progress of microporous modified atmosphere packaging and its extension on shelf life of fresh foods. The latest applied researches were described in a comprehensive manner, particularly fruits and vegetables. Besides, this article also covered theoretical support and analysis, including the perforation mode, air permeability mechanism and mathematical model of microporous film, the characteristics of fresh foods, pore parameters and traits of film materials. This paper payed attention to the application of environmentally friendly degradable film materials (biological film materials, nano materials) in fruits and vegetables preservation. Research has shown that the degradable material can enlarge the fresh-keeping effect of microporous modified atmosphere packaging, which is worthy of further research and development. Finally, the development trends and directions in the future were discussed.
近年来，由于其可调透气性和低成本加工，微孔改性气氛包装受到了广泛关注。随着新鲜食品工业的发展和需求的增加，改性气氛包装中薄膜的有限透气性不能满足新鲜食品（特别是蔬菜和水果）的保鲜要求。微孔膜可以根据新鲜食品的生理代谢特性灵活调节透气性，逐渐成为蔬菜和水果保鲜领域的一项保鲜技术。本文综述了微孔改性气氛包装及其在延长新鲜食品货架期方面的研究进展。全面描述了最新的应用研究，特别是水果和蔬菜。此外，本文还涵盖了理论支持和分析，包括微孔膜的穿孔模式、透气性机制和数学模型、新鲜食品的特性、膜材料的孔参数和特性。本文关注了可生物降解薄膜材料（生物膜材料、纳米材料）在果蔬保鲜中的应用。研究表明，可降解材料可以放大微孔改性气氛包装的保鲜效果，值得进一步研究和开发。最后，讨论了未来的发展趋势和方向。
