【摘要】 以小站稻大米越选3#为试材,采取定量气流法,研究气调保鲜的阈值、不同气体环境对大米品质指标变化的影响.根据大米的生理特点,研制防霉、防潮、延缓陈化大米专用保鲜膜.研究结果表明,大米对膜的阻隔性能要求极严格,大米PVC专用保鲜膜的最适透气比0ρ为1.3-7.0,并筛选出防霉、延缓潮和防陈化的专用PVC保鲜膜.

【Abstract】 Using milled rice of Yuexuan3#(Xiaozhan paddy),the quantitative air current treatment is adopted to study the atmosphere threshold value of rice with modified atmosphere and the influence of different gas environment on the quality index of the rice.In order to develop special-purposed membrane that is mouldproof,dampproof and delays aging rice,the physiological characteristic of after-harvest rice is analyzed.The results indicate that the obstructing property of membrane for rice preservation is demanded extremely strictly,the optimum ventilative ratio of special-purpose membrane is confirms to be 1.3-7.0. A kind of mouldproof,dampproof and age-delaying PVC membrane for rice preservation is selected.
