Publication number: 20220410440Abstract: The present invention relates to two-dimensional and three-dimensional shaped parts and composite materials made of popcorn and synthetic and/or natural binding agents which are cured in automatic moulding machines or similar pressing installations by means of radio wave technology or microwaves. By means of these technologies, light-weight, two-dimensional and three-dimensional shaped parts and composite materials can be produced for packaging, as interior and exterior parts (for example in automobile and mobile-home construction), shock absorbers, space-dividing elements, furniture, consumer goods, for the building trade of for heat insulation.Type: ApplicationFiled: February 24, 2021Publication date: December 29, 2022Applicant: Georg-August-Universität Göttingen Stiftung Öffentlichen RechtsInventors: Alireza Kharazipour, Markus Euring

Publication number: 20220295830Abstract: The invention relates to a method for producing dry pet food articles, dry pet food articles produced by the method, and the use of the resulting dry pet food articles. The dry pet food articles are produced by a method that includes the steps of providing a moulding material by contacting popcorn with a binder composition, the binder composition including a protein, a sugar alcohol, and water; and forming an article from the moulding material by administering heat and/or pressure to the moulding material in a mould. The dry pet food articles can be produced easily and provide very low caloric value per weight and particularly per volume, while also being well received by pets in terms of taste and texture.Type: ApplicationFiled: March 16, 2022Publication date: September 22, 2022Applicant: Georg-August-Universität Göttingen Stiftung Öffentlichen RechtsInventors: Markus Euring, Alireza Kharazipour
