Abstract:Toachieverapidandaccuratedeterminationoftheagingdegreeoftobaccolamina，thisstudyinovatively proposedadualindicatorsynergistcevaluationmethodforpHvalueandabsorbance.Theexperimentselected5tobaccoraw materialswithdiferentspecificationsin2021，andtrackedandmonitored90samplesthrough9consecutivesamplingcycles (sampling interval of 30 days). The pH and absorbance value were simultaneously measured using parallel experimental methods, andthechangerulesandcorelationwithstoragetimeweresystematicallanalyzed.TheexperimentalresultsshowedthatthepH valueofthetobaccolaminadecreasedsignificantlyduringstorage，whiletheabsorbancevaluecontinuedtoincrease.Thetwo showed a high negative correlation.Itwasverified by regressionanalysis that therelationship between pH and absorbance was linear and passed the significance test F≥62.7500 一 P
