I need to make a product shelf stable

I want to scale a production of an agricultural product and to make it shelf stable and am open to suggestions on how to do so. The product I'm making is an agricultural product and my preferred method of making it shelf stable is natural methods. Natural methods include such things as removing water from the product and increasing the acidity or even adding enzymes things of that sort. If you have any experience helping clients make their products shelf stable using natural methods, I would love to hear from you and learn more about how you can help me.
