目的:研究湿冷与臭氧技术对双孢蘑菇的保鲜作用。方法:分别用0.02%焦亚硫酸钠水溶液、4.28mg/m3臭氧气体以及一定浓度的臭氧水处理双孢蘑菇,在温度3～5℃、相对湿度90%～95%的条件下贮藏,探讨各种处理对双孢蘑菇的保鲜效果。结果:4.28mg/m3的臭氧气体加剧了双孢蘑菇的褐变,而将5.0g/h的臭氧气体通入2L冰水中2min,制得的一定浓度的臭氧水不仅不会促进褐变,还会起到较好的护色、保鲜作用,其效果略优于0.02%的焦亚硫酸钠水溶液。结论:臭氧水的保鲜效果好,具有广阔的应用价值。
Objective: To study the preservation of Agaricus bisporus with wet and ozone technology. Methods: Agaricus bisporus was treated with 0.02% aqueous solution of sodium metabisulfite, 4.28mg / m3 ozone gas and a certain concentration of ozone water, respectively, and stored under the conditions of temperature 3 ~ 5 ℃ and relative humidity 90% ~ 95% On the bisporus preservation effect. Results: 4.28mg / m3 of ozone gas exacerbated the Agaricus bisporus brown, while the 5.0g / h of ozone gas into 2L ice water 2min, a certain concentration of ozone water not only does not promote browning, but also Will play a better color protection, preservation effect, the effect is slightly better than 0.02% sodium metabisulfite solution. Conclusion: Ozone water preservation effect is good, has broad application value.
