drinkable hydrosol without preservatives

Hi
My name is Ashtiani I'm a founder of in bloom drops, line of hydrosol drinkable herbal water.
we are based in London UK.
I'm not a chemist and seems no one in the Uk is able to help us with the production of non preservative herbal drops.
to my understanding the bottles need to be sterilized and the hydrosol pasteurized again.
is this doable?
whats your thoughts on this.

    You won't use any preservatives? Not even those commonly used in the food/beverage industry?

    I think you're asking for trouble

    If you pasteurise it, a herbal infusion, like most beverages, will be okay for 2-3 days in the fridge.
    Else, use single use doses (sterile/UHP), add >40% sugar, or add glycerol or similar polyols or ethanol at sufficiently high levels.

    Hi
    they come in sterile bulk bottles and pasteurized but in order to re bottle them we need to pasteurize.
    the expiry date on these are 2 years and after opening as long as you keep them away from light and cool place for 3 weeks.

    I have checked other brands and seems like everyone is using glycerol.

    The only way to have them sterilized in the bottle with no preservatives is a perfect closure system, clean bottles and gamma radiation. And once opened, well then it's bugfood.

    @Golnazashtiani actually hydrosol obtained by distillation did not need any preservative for one year or more.
