Ultrafiltration Case Study: Sepallo Foods Turns Over A New Leaf

Sepallo Food Ingredients produces a successful line of leaf-juice powders made from the leaves of wheat, barley, oat, and alfalfa. Sepallo markets these powders primarily as bulk ingredients to manufacturers in the food and natural products industries throughout North America, either as a stand-alone product or as a base in other products.

When Sepallo discovered that the majority of these leaves contain extremely high levels of protein, a new product opportunity was born. However, extracting the protein from the juice using traditional methods, such as centrifugation or heat processing, presented a number of technical challenges, including low protein yield, maintaining protein structure and purity, and preserving product color.
