Preservatives are very much required ingredients for long storage of edibles.
These preservatives can be good or harmful depending upon their nature.
You cannot avoid avoid these preservatives completely but can limit their intake by avoiding commercially available/packed available edibles.
You can use home made products, because most of them have natural preservatives like salt and oil, which are not harmful or less harmful.

If you want to avoid them completely, you can prepare things at home in lesser quantity so that can be consumed in limited time. In that case, you will not need to store them for longer.

In some places, ladies provide services of preparing pickles, sauce, papad, jam, etc on order. From there also you can get things without preservatives.
