摘　　要：针对瓶装碳酸饮料流转迅速、货架期长、检验周期无法满足生产和销售需要这一问题,使用红外传感检测二氧化碳浓度,建立了快速检测碳酸饮料货架期的方法。试验表明:使用红外传感测试和数学推导可以大大缩短检测时间,同时测试重复性有所提高,该方法可以满足企业快速生产、销售的需要,也可以保证下游灌装企业能够准确地预估产品的货架周期,保护消费者利益;红外传感法还可以测试温度对于二氧化碳渗透量的影响,从而为碳酸饮料较严峻储存环境下的存放周期提供测试分析方法。Polyethylene terephthalate（PET） bottles for carbonation drink were produced rapidly and had long shelf life normally.The present inspection can not meet the needs of marketing.Infrared sensor method was used to detect concentrations of carbon dioxide,which was a rapid detection method for shelf life of carbonated beverages.Test results showed that using the infrared sensor testing and mathematical derivation can greatly shorten test and evaluation time with improved repeatability.This method was useful for the production enterprises and downstream companies to accurately forecast the shelves cycle.It is also useful to protect the consumers＇ interests.Infrared sensor method can also test the temperature effect on the permeation of carbon dioxide,thus the tough storage environment and the storage cycle can be analyzed.
