【摘要】 本文以香蕉果实为例,在不同的温度条件下(10、15、20、25、30℃)用已测得透气系数的低密度聚乙烯薄膜(LDPE)来进行香蕉的薄膜包装(MAP)贮藏。用数理法和密闭法分别测定MAP条件下香蕉在贮藏期间内的呼吸强度,并对两种测定方法的测定结果进行了比较。研究结果表明:密闭法测得的果蔬呼吸强度比数理法测定的结果偏低。两种方法所得结果的差异,可以从各自不同的测定原理得到解释。更多还原

【Abstract】 Bananas sealed in Low Density Polyethylene(LDPE) bags with known p er meability coefficient were incubated at different temperatures(10,15,20,25,30℃) until O2 and CO2 levels in the packages reached a steady state. Bananas respira t ion rate was determinded by two methods. One was the Numeral method (NM)and th e other was the traditional sealed container method(TSCM).In addition, the resu lts determined with two methods were compared. The results showed that banana r espi ration rate determined with the TSCM was lower than the one determined with the NM. The difference could be deciphered through respective principles of th e dete rmination method.更多还原
