Hello Everybody,
Actually I am planning the analysis of the vitamins, minerals and other phyto-nutrients of some fresh green vegetables plants samples. since collection of samples and bring them to lab may take time of few days. Could you please share the different experiences/methods of preserving the green samples so that their composition remain intact for the calculation of exact nutrient concentration in sample.
In my view, the best way would be freezing in liquid nitrogen (-180 C) but that might not be feasible in your situation. Solid CO2 (-78C) would be my second choice, but that also might be a problem.
Drying might affect some of your nutrients, so you might have to skip some of them in that case.
Good Luck with your study
Yes Sir, we are shed- drying the planting material already for further analysis. But This time I want the fresh sample analysis. thank you for your kind suggestion.
