摘要: 双孢蘑菇味道鲜美、营养价值丰富,但是其呼吸代谢旺盛、货架期短,为了解决其不耐贮藏的问题,本实验用不同水平的CO2(5%、10%、20%)对双孢蘑菇进行短期厌氧处理,并以纯N2处理作为对照。通过对双孢蘑菇采后品质指标(质量损失率、亮度、褐变度、质构、味觉值)和生理指标(呼吸速率、相对电导率、丙二醛含量、抗氧化物质含量)进行测定,发现低水平CO2(5%左右)短期厌氧处理的保鲜效果最好,其在降低双孢蘑菇的呼吸速率和质量损失率、抑制褐变、维持硬度和弹性、延缓细胞膜通透性的升高、减轻氧化损伤、保持鲜味等方面有良好的效果。但是高水平CO2处理保鲜效果相对较差,20% CO2组处理的双孢蘑菇褐变严重,细胞膜通透性升高,电解质渗漏严重,还伴有一定程度的氧化损伤。

Abstract: Agaricus bisporus tastes good and is nutritious, but its respiratory metabolism is strong and consequently its shelf life is short. In order to solve the problem of its poor storability, Agaricus bisporus was stored for a short period of time under oxygen-free modified atmospheres containing different levels of CO2 (5%, 10% and 20%) or a pure nitrogen atmosphere as a control and evaluated for postharvest quality indicators (mass loss, lightness, browning degree, texture, and taste value) and physiological indicators (respiration rate, relative conductivity, malondialdehyde (MDA) content, antioxidant contents). We found that a low-CO2 (5%) atmosphere was the most effective in preserving the quality of Agaricus bisporus, which could reduce the respiration rate and mass loss, inhibit browning, maintain firmness and springiness, delay the increase of cell membrane permeability, reduce oxidative damage and maintain the umami taste of Agaricus bisporus. But the preservation effect of a high-CO2 atmosphere was relatively poor, and the mushroom stored under a 20% CO2-containing atmosphere showed serious browning, increased cell membrane permeability and consequently serious electrolyte leakage, accompanied by oxidative damage.

Key words: Agaricus bisporus; short-term oxygen-free; CO2 level; postharvest physiology quality
