The invention relates to a method for detecting the
mildew-proofing performance of household electric appliances. The method comprises the following detection steps: preparing and pre-treating a sample; selecting equipment models and preparing a
reagent and a culture medium; preserving and activating strains and preparing a
spore solution; establishing an OD value-viable content logarithm value lgCB
standard curve; establishing an ATP concentration logarithm value lgCA-relative
fluorescence intensity logarithm value lgIA
standard curve and calibrating viable
bacteria CA of an inoculating bacterial solution; performing sample
inoculation, cultivation and eluting reclamation; detecting IA of reclaimed solution and estimating CA and TA of ATP concentration of living
bacteria of the reclaimed solution; calculating an antibacterial ratio R or
antibacterial activity A; and evaluating the result. The method is characterized in that the R or A represented
mildew-proofing performance of household electric appliances can be accurately and quantitatively tested by applying an ATP fluorophotometer. According to the method, a
control sample and an antibacterial sample after 0 hour of
elution reclamation contact and 48 hours of cultivation are specified, the IA of the reclaimed solution is detected, and R or A is represented and calculated by lgIA. According to the ATP bio-
fluorescence lgCA-lgIA
standard curve method for detecting the
mildew-proofing performance of household electric appliances, product quality improvement is supported by scientific and advanced detection techniques.
