有效的包装可以延长香菇的保质期和贮藏质量。本研究旨在研究纳米sio2 /纳米tio2负载聚乙烯醇（PVA）包装对双孢蘑菇（Agaricus bisporus）保鲜的影响。在4 +/- 1℃和90%相对湿度的条件下储存15天，评估了质量特性，包括失重、呼吸速率、颜色、总可溶性固结物、pH、丙二醛含量、电解质泄漏率、总酚类物质、抗坏血酸、多酚氧化酶、过氧化物酶、微生物生长和微观结构。结果表明，用纳米sio2 /纳米tio2负载PVA薄膜包装的蘑菇在pH值、颜色、总酚类物质、抗坏血酸和抗菌活性方面均优于PVA或聚乙烯薄膜包装的蘑菇。它们可以使体重减轻、呼吸速率、电解质泄漏速率和丙二醛积累减慢，并降低多酚氧化酶和过氧化物酶活性。这些积极的影响可能归因于他们有效地控制了这些包装中的O-2和CO2。
Effective packages can extend shelf life and quality of mushrooms in storage. This study is to investigate the effects of nano-SiO2/nano-TiO2 loaded polyvinyl alcohol (PVA) packages on preservation of Agaricus bisporus. Quality properties, including weight loss, respiration rate, color, total soluble solid, pH, malondialdehyde content, electrolyte leakage rate, total phenolics, ascorbic acid, polyphenol oxidase, peroxidase, microbial growth and microstructure have been evaluated in 15 days storage at 4 +/- 1 degrees C and 90 % relative humidity. Results showed that mushrooms packaged in nano-SiO2/nano-TiO2 loaded PVA films exhibited a better retention in pH, color, total phenolics, ascorbic acid and antimicrobial activity than those with PVA or polyethylene films. They can make the weight loss, respiration rate, electrolyte leakage rate and accumulation of malondialdehyde more slowly, and lower polyphenol oxidase and peroxidase activities. These positive effects might be attributed to their effectively control of O-2 and CO2 in these packages.
