Penford Food Ingredients added to its line of modified starch systems with the launch of PenTech 8500, a casein replacement ingredient. This modified potato-based food starch incorporates the company’s PenNovo technology. PenTech 8500 reduces the use of high-priced rennet casein to 10% in a standard imitation cheese formulation, while still maintaining superior melt, stretch and mouth-feel in cheese products. Using PenTech 8500 reduces casein usage by 50%.
