Patent number: 11001700Abstract: A process for manufacturing eggshell powder for use in the production of bio-based products is provided. The process involves exposing a quantity of eggshell to high air speed at room temperatures to pulverize the eggshell and separate the eggshell component from the inner membrane component. Thus, the process avoids the use of high temperatures and other harsh chemical treatments to remove the inner membrane from the eggshell thereby resulting in an eggshell material that retains the original lipid-protein structure of the native eggshell from which the powder derives. Accordingly, an eggshell powder composition is provided that is substantially free of inner membrane material and possesses a lipid-protein structure substantially similar to that of the eggshell from which the powder is derived. A polymer composite composition comprising an eggshell component and a polymer component is also provided.Type: GrantFiled: November 16, 2012Date of Patent: May 11, 2021Assignee: Tyson Foods, Inc.Inventors: Yongcheng Liu, Ke-Wei Wang, Michael Blanchard, Clive Li, Gary Metzger

Patent number: 8211657Abstract: The present invention is directed to satisfying the need to detect microbial contamination of food products. The described bioseparator/bioreactor coupled with an optical/electrochemical biosensor was able to specifically detect E. coli O157:H7 from 8.8×101 to 8.8×106 CFU/ml in 2.5 hours without any enrichment. Using this invention, concentrations of S. Typhimurium ranging from 8.6×102 to 8.6×106 CFU/ml in pure culture were detected in 2 hours without any enrichment. The invention may also be used for the detection of S. Seftenberg, which has the same sensitivity as S. Typhimurium. Other pathogens such as L. monocytogenes and S. Heidleberg did not interfere with the detection. The optimum inner diameter of the 25 cm long column for the detection of E. coli O157:H7 is 250 ?m.Type: GrantFiled: December 13, 2010Date of Patent: July 3, 2012Assignee: The Board of Trustees of the University of ArkansasInventors: Yanbin Li, Yongcheng Liu

Publication number: 20050112557Abstract: The present invention includes a new, sensitive, rapid, portable, and inexpensive biosensor for detection of biological agents. The inventors develop a mesoporous-chip based biosensor device that is able to detect very low-level pathogens in a relatively short time. This biosensor device is designed in a way that significantly increases the reaction area, and constructed by immobilizing antibodies onto a mesoporous chip surface. The antibody-immobilized mesoporous chip is used as a bioseparator for separation of pathogens or other biological agents when the sample goes through the chip pores. Then an enzyme labeled antibody solution is injected into the chip pores, and a sandwich structure of immuno-complexes (enzyme labeled antibody-biological agent-antibody immobilized on chip) can be formed within the chip pores. The porous chip will also be a bioreactor for catalysis of the enzyme reaction, resulting in easily detected chemical species.Type: ApplicationFiled: September 22, 2004Publication date: May 26, 2005Inventors: Yongcheng Liu, Yixiang Duan
