Good evening I wonder if there is a solution to sterilize my plant hydrosol without altering the compounds.The first microbiological control test showed contamination likely originating from the glassware.
Hello,
To avoid altering the components of your samples, you can carry out sterilization by filtration.
Use the millipore filters, it will retain the microorganisms and your sample will not be damaged.
Hello
the filtration membrane can affect hydrosol Hi containe some essentiel oil
can i use a Buchner and a filtre membran of 0.22 micometre
Hello,
I have never used the Büchner to filter in aseptic conditions.
the 0.22 µm membrane allows to maintain microorganisms, however, can you ensure aseptic conditions for the entire Büchner device?
Filtration is not enough - it merely removes contaminating microbes in the filtrate that will be immediately recontaminated by air, nonsterile containers, manipulation, dispensing etc.
You'll need a preservative to maintain control. Properly preserved in production, no filtration is necessary.
Phil Geis I had my hydrolat UV tested and it seems that the problem is solved but to prevent it in the future, please suggest a preservative.
Zahida Hatif Mahdi Thank you for the answer .
Regarding microfiltration is there a risk that the membrane will absorb traces of essential oils contained in the hydrosol?
