Publication number: 20230292792Abstract: A method is provided for treating pathogens with a lipid-based carrier and organic acids. More specifically the lipid carrier may have a pKa of 2.5-4.0 and/or may be acid oil, such as Acidulated Vegetable Oil. Furthermore, compositions consistent with the method are provided wherein the lipid-based carrier increases antipathogenic action of the organic acid. For example, the carrier may have a pKa that increases the antimicrobial action of the organic acid and/or an additional essential oil. The carrier may be acid oil, such as Acidulated Vegetable Oil derived from soapstocks and/or gums, but is not limited to same. The organic acid may include, but is not limited to, formic acid, acetic acid, propionic acid, butyric acid, and combinations thereof.Type: ApplicationFiled: May 30, 2023Publication date: September 21, 2023Applicant: RRIP, LLCInventors: Mohan Prasad A.

Patent number: 11549081Abstract: Provided are methods to destabilize emulsion feedstocks. In the methods, a moderate temperature is applied to the feedstock to create a first mixture. The moderate temperature may be between 120 and 220 degrees Celsius. The first mixture is mixed at the moderate temperature, such as by staged mixing in some embodiments. Moreover, the first mixture is retained at the moderate temperature for up to six hours. The first mixture is separated into an oil phase, convoluted phase, and a water phase. In some embodiments, the moderate temperature may be 125 to 150 degrees Celsius, such as between 125 and 130 degrees Celsius. Moreover, the first mixture may be retained at the moderate temperature for between forty-five minutes and four hours, such as from two to four hours. The separation may occur at the moderate temperature.Type: GrantFiled: April 5, 2017Date of Patent: January 10, 2023Assignee: RRIP, LLCInventors: Mohan Prasad A. Dasari, Hugh Tallant Warren

Patent number: 11247964Abstract: The present invention provides methods of processing lipid materials such as soapstock, wet gums and dry gums. Enzymes are utilized to catalyze hydrolysis of the lipids materials to recover fatty acids. Addition of organic acids and/or polyols improved yield of fatty acids and reduced formation of emulsion. Lipid materials can be formulated with other agricultural products as new value-added animal feed products. Further, a process for concentrating nitrogenous compounds such as choline, inositol, ethanolamine and serine from phospholipid materials obtained as byproducts from vegetable oil refining is provided. The process involves performing hydrolysis of the gum based products in the presence of an alcoholic solvent and acid catalyst. Post hydrolysis, gums breakdown to oil and water phases which are further separated and concentrated. These concentrated products may be further fractionated to concentrate individual nitrogenous compounds.Type: GrantFiled: April 18, 2016Date of Patent: February 15, 2022Assignee: RRIP, LLCInventors: Mohan Prasad A. Dasari, Abdullah A. Mahfuz, Shashank Ravi, Hugh Tallant Warren

Patent number: 10745643Abstract: Methods for producing oil from distillers corn oil having high free fatty acid content are provided. In the method, distiller's corn oil is treated with a mixture including an alcohol to result in a low-free fatty acid oily phase and an alcohol phase. The mixture may also include an alkali. The alcohol may be a monohydric alcohol and an aqueous alcohol, such as an aqueous alcohol having a concentration of at least about 15% alcohol-by-weight. The low-free fatty acid phase may include oil and at least one impurity. The low-free fatty acid phase may be cooled, and the oil may be separated from the at least one impurity using membrane filtration.Type: GrantFiled: August 27, 2018Date of Patent: August 18, 2020Inventors: Charles C Gallop, Mohan Prasad Dasari, Hugh Tallant Warren, Kidron Joel Knox
