A German inventor, Wilhelm Hansen, has been awarded a US patent to protect his process for making cheese, curd and yoghurt from soya beans. Hansen refers to the growing number of consumers opting for soy milk over cow's milk, and the increase in the number of people who are required to, or choose to, eat vegetarian food exclusively. His process aims to substantially eliminate the taste of soybeans in dairy substitutes such as soy-based cheese and yoghurt.
