摘　　要：为预测灭菌亚麻籽仁酱的保质期,以市场上购得的亚麻仁酱为试验原料,用过氧化值和酸价作为理化指标,以菌落总数、大肠菌群和致病菌为卫生指标,采用经典恒温加速试验法,在恒温36℃和46℃的条件下进行试验。根据货架期试验(ALST),θ(ST1)=θ(ST2)×Q10(T2-T1),计算出常温下(25℃)的亚麻仁酱保质期。结果表明,采用耐蒸煮塑料包装袋包装的亚麻籽仁酱的Q10=1.227,常温下(25℃)下亚麻籽仁酱的保质期为317 d。建立了快速确定灭菌亚麻仁酱保质期的方法,该方法对缩短相关产品的开发周期具有参考意义。In order to predict the shelf life of flax seed kernel paste, taking the flax seed kernel collected form market as raw material, peroxide value and acid value as physicochemical indexes, total number of bacterial colony, coli group and pathogenic bacteria as hygienic indicators, the test was carried out by classical constant temperature accelerated test at temperatures of 36 ℃ and 46 ℃. Based on the shelf life test ALST： θ（STI ） = 0（ST2）×Q10（T2-T1）, the shelf life of the paste at room temperature （25 ℃ ）was calculated. The results showed that the shelf life of the flax seed paste was 317 days with Q10 = 1. 227 under 25 ℃, packed with boiling - resistant plastic package. The method of rapid determination of the shelf life of the sterilized flax seed paste was established, which has reference value for shortening the de- velopment periods of the relevant products.
