ZEEN Tech is a Swiss food technology firm that specializes in innovative water-based food processing technologies for the manufacture of snacks and food products. The company has created a proprietary method that allows for frying in pure water without the need of oil or air, enabling the creation of snacks, chips, crisps, and other food products with no added fat from frying medium.

The ZEEN Tech system combines numerous operations into a single manufacturing line, such as frying, drying, expanding, roasting, puffing, sterilizing, reheating, and baking, without requiring equipment changes between applications. The method is intended to work with a variety of raw ingredients, regardless of kind, allowing for versatility in snack and meal formulations. Key operational advantages include oil-free and air-free processing, reduced energy consumption (estimated to be 80-87% lower than conventional oil or air systems), and process integration targeted at minimizing operating costs. 

The company's equipment is designed for industrial food manufacturers, food service operators, fast food chains, agriculture producers, and gourmet applications. ZEEN Tech also provides partners with product testing and production launch services through its own technology platform.
