Patent number: 11853832Abstract: Material in a supply chain is tracked by a method of applying a DNA taggant set to a first batch of the material produced by a first supplier of the material. The DNA taggant set corresponds to a tag string corresponding to the first supplier. The first batch is aggregated with a second batch to create an aggregated lot. A sample is selected from the aggregated lot and tested to determine a DNA taggant set of the sample. After selecting a sample from the aggregated lot, the sample may be labeled with a grade and then placed in a receptacle corresponding to the grade.Type: GrantFiled: August 26, 2022Date of Patent: December 26, 2023Assignee: SafeTraces, Inc.Inventors: Antonios Zografos, Laurie M Clotilde

Publication number: 20230366866Abstract: Food distributed to consumers through a distribution chain may be traced by tagging the food with DNA tags that identify the origin of the food, such as the grower, packer and other points of distribution, and their attributes. This makes it much quicker and easier to trace the food in case of food contamination or adulteration. Preferably these attributes indicate the field, location, crew and machine used to grow and process the food, and the dates of the various steps of food harvesting, processing and distribution. Natural or synthetic DNA pieces may be used to tag items, including food items. Multidigit binary or other types of bar codes may be represented by multiple types of DNA. Each digit of the bar code may be represented by one, two or more unique DNA pieces.Type: ApplicationFiled: June 27, 2023Publication date: November 16, 2023Inventors: Antonios Zografos, George Roy Farquar

Patent number: 11801512Abstract: A dispersant system comprises a plurality of taggant vessels, each having a taggant that corresponds to a position in a tag string and a computer controller convert the tag string into a selection of a taggant set while computer-controlled valves allow or block a flow of taggants to a manifold output tube. From the output tube, a mix of the taggants flow to form a dispersant formed according to the tag string. A nozzle disperses the dispersant onto an object to be tagged, possibly atomized with air. The taggant can comprise a DNA taggant comprising a static portion and a dynamic portion that is unique to each tag string position. Tag strings for adjacent lots might have a low Hamming distances to reduce cross-contamination and/or have redundancy for error detection and correction and selected so that consumption of taggants evens out over the plurality of taggant vessels.Type: GrantFiled: January 8, 2021Date of Patent: October 31, 2023Assignee: Safe Traces, Inc.Inventors: Antonios Zografos, Laurie Clotilde

Publication number: 20230143910Abstract: A method of producing an aqueous solution of zein suitable for forming edible coatings includes combining zein with an alcohol-free, non-corrosive amphipathic carrier solvent (e.g., [1,3]-propanediol), and adding a surfactant (e.g., surfactin) thereto, forming a Phase I solution. The surfactant may be non-ionic or anionic as determined by the type of zein being used. The Phase I solution is combined with a Phase II aqueous solution including primarily water without alcohol to provide an aqueous coating solution of zein. A plasticizer (e.g., polyethylene glycol) or fatty acid (e.g., lauric acid) may be added to the Phase II solution to enhance the zein coating. The resulting coating solution may then be applied on food, and dried, to form an edible coating.Type: ApplicationFiled: April 16, 2021Publication date: May 11, 2023Applicant: Akorn Technology, Inc.Inventor: Antonios Zografos

Publication number: 20220080076Abstract: A sanitation management system maintains records of exemplary locations on an item to be sanitized and indicates those locations to a person or system charged with applying a pathogen surrogate prior to a sanitation process. The sanitation management system maintains records of where the pathogen surrogate was applied prior to the sanitation process. Following the sanitation process, the sanitation management system indicates to an inspector, or an inspection system, locations of where the pathogen surrogate was applied for the purpose of facilitating testing of the sanitation process by checking for the presence of the pathogen surrogate at some or all of those locations. This can ensure that the inspection process is relevant to the sanitation process and less likely to generate false negatives where the inspection finds a lack of the pathogen surrogate not due to cleaning, but due to lack of application of the pathogen surrogate.Type: ApplicationFiled: September 27, 2021Publication date: March 17, 2022Inventors: Antonios Zografos, Laurie M.

Publication number: 20210181169Abstract: A pathogen surrogate, formed by a DNA tag or bar code and a carrier, is described for use in the validation and verification of sanitation, such as in food processing operations and for wash water systems for fresh produce. The carrier material is selected so that the pathogen surrogate mimics the behavior of a pathogen when subjected to a sanitation operation. One or more surrogates can be introduced in to an environment, which is then subjected to sanitation process, followed by a detection process using the DNA tag of the surrogate.Type: ApplicationFiled: February 26, 2021Publication date: June 17, 2021Inventors: Antonios ZOGRAFOS, George Roy FARQUAR, John Mark CARTER
