3:2
Bacteriostatic antibacterial
The process of inhibiting or hindering the growth and reproduction of bacteria and their activity by chemical or physical means:
4 Determination methods and selection of test bacteria
4:1 Choice of determination method
4:1:1 Ordinary samples
Choose the appropriate measurement method according to the sample performance and usage: For samples containing leaching antibacterial components, or fiber raw materials (including
For samples with antibacterial function and good water absorption, carrier antibacterial test (Chapter 5) can be selected for quantitative measurement
For samples containing leaching antibacterial ingredients, if qualitative determination is carried out, the inhibition zone test (Chapter 6) can be selected; for samples containing non-dissolving
For samples of antibacterial ingredients, after the identification test is confirmed, the shaking flask test (Chapter 7) can be selected for quantitative determination:
Judgment method of sample water absorption: Cut the sample into a sample with a size of 2:0cm×3:0cm (the samples can be stacked, but the number of pieces shall not exceed
3 pieces), drop 100 μL of bacterial suspension on the surface of the sample, if the bacterial suspension can be completely absorbed by the sample, it is considered that the sample has good water absorption
Samples, such as antibacterial tissue paper:
4:1:2 Special samples
Select the corresponding determination method according to its sample characteristics: in identifying whether the antibacterial components in food contact paper, cardboard and paper products occur
