Benefits of technology

The present invention creates compositions that can be used as tools to improve hygienic sanitation conditions of processing equipment and to improve antimicrobial processing aide performance in the food, feed, beverage, processing, and service industry. The compositions are made from GRAS or food additive ingredients that are considered safe by the Food and Drug Administration and the Environmental Protective Agency. The compositions can be used as a food grade additive packet that can be mixed into existing food processing aides or as a standalone solution for improving sanitation and food processing aide performance. The resulting solutions have improved function and can be quantitatively measured using ultraviolet light. The invention allows for novel techniques using ultraviolet fluorescence to evaluate the performance of antimicrobial delivery systems with regard to adequacy of food surface coverage.

Problems solved by technology

Chemical and microbiological contamination caused by inadequate sanitary design of equipment or ineffective sanitation procedures are very serious risks in food, feed and pharmaceutical production.
Very low levels of contamination can cause serious illness.
Chemical residue can build up on surfaces or in niches and if not properly removed the compounds can cause cross contamination.
LM organisms are transported out of the niches by the motion of the equipment and or fluids, thus contaminating food contact surfaces and food.
Poor equipment sanitary design conditions are easily missed by ineffective monitoring and verification of the cleaning and sanitation procedures.
However, a common problem associated with detergent residue testing is that detergent suppliers will not provide specific compositions and rapid test kits are not available which makes it difficult for the user to determine if they are completely removed.
The most common practice of visually evaluating the sanitary condition of equipment is limited when the objective is to clean to a microbiological and parts per million level of sensitivity.
Microbiological swab sampling is limited in the area (i.e., square inches) tested, the cost per test and time for results.
Limiting factors for ATP swab sampling include sample size and cost per test.
Similarly, chemical residue tests are limited due the lack of rapid test kits, small sample size, time and cost associated with the analysis.
Traditional routine inspection methods are designed to evaluate a budgeted number of routine sample points instead of the entire processing line and all the potential niches, and are therefore subject to miss unhygienic conditions.
Invalid food safety processing aides or interventions incorporated in food processing facilities pose the risk of causing food borne illness and public health incidents.
And history has shown that facilities with scaled up processing aide delivery / intervention systems have been associated with food borne illnesses and product recalls.
Delivering antimicrobial solutions onto food so that adequate surface coverage is achieved in a processing plant is difficult.
And quantifying adequate coverage is equally as difficult.
Often times the spray system is not accessible for observation of performance and at best, measuring coverage is subjective.
It is difficult to distinguish between the intervention and rinse water when visually evaluating the surface of the treated product.
Spray coverage and / or contact time can be inadequate from the onset of installation or can be diminished when spray nozzles malfunction or get plugged.
At best it is difficult during normal line speeds to visually determine if the solution is covering the surface area per the intervention design objective.
However, use of such methods discovers areas not properly sprayed after production and since the measurement is not real time corrective actions during production are not possible.
A common deficiency was reported that antimicrobial or hot water interventions, such as sprays, did not reach all parts of carcasses and fabricated cuts.
And as a result of incomplete coverage, interventions were likely less effective than intended, and this ineffectiveness may contribute to the production of contaminated products.
But fresh cut melons pose special food borne illness risks.
Unlike other fruits, they are not acidic and the act of processing into fresh-cut increases the risk of pathogen contamination and growth once they are peeled or sliced.
However, previous disclosures may not combine the specific GRAS ingredients or methodology for application and analysis as intended in this embodiment.
Discovery of presence on processing equipment sections and niches indicates that those areas were not properly cleaned and / or designed for ease of cleaning.
Although these patents disclose methods to determine unclean hands after a marker has been applied they do not utilize the unique combination of GRAS or food additive fluorescent vitamins, surfactants, emulsifiers and acidifiers to provide a penetrating marking composition.
It is disruptive and costly to test processing aide delivery system performance in the actual food plant where the equipment is intended to be used.
In a food plant environment the performance of the intervention cannot be validated or verified by inoculating food samples with pathogenic organisms, treating the food through the intervention system and then measuring the reduction of pathogenic organisms.
Introducing known pathogens in a food plant is not acceptable.
Regulatory approved antimicrobial solutions are difficult to visually measure after they have been applied to food products.
However, dyes change the visual appearance of the food product and in many applications this outcome is not desired.
Most intervention spray cabinets are not accessible during production which adds risk that malfunctions could occur un-noticed.
Prior art for measuring the coverage of a direct food contact processing aid / antimicrobial intervention is limited.

example 1

[0047]The current inventors tested the use of Sodium Lauryl Sulfate (STEPANOL® WA-100 NF / USP) and Glyceryl Laurate (Colonial Monolaurin-Ultra-Pure Glyceryl Laurate) to increase the coverage and penetration of component solutions applied to processing equipment in which the solution is removed from food, feed or pharmaceutical contact surfaces prior to production. Glyceryl Laurate and a mixture of propylene glycol and ethyl- W-lawoyl-L-arginate hydrochloride (A&B Ingredients CytoGuard LA) was used by the inventors for applications associated with direct food contact and was shown to increase coverage and adherence / contact time. Food grade Riboflavin, Folic Acid and Quinine were selected from the many fluorphores available because they were shown to have synergy for the purpose of the tracer concept of the invention.

[0058]Tests were performed on two stainless steel meat tenderizer rollers. The tenderizer knife rollers are made of 48 circular knives with ¼ inch circular spacers in between the blades. At each blade spacer junction there is a micro niche. Two formula compositions in potable water base material were compared for performance, one with and one without surfactant or emulsifier. Formula 1 contained 750 ppm Riboflavin, 300 ppm Folic Acid as fluorescent tracers, 750 ppm of the surfactant Sodium Lauryl Sulfate, 1,500 ppm of the acidulate Citric Acid Monohydrate and 750 ppm of the emulsifier Glycerol Monolaurate (Monolaurin) in potable water base material. Formula 2 contained 750 ppm Riboflavin, 300 ppm Folic Acid as fluorescent tracers and 1,500 ppm Citric Acid Monohydrate in potable water but did not contain Sodium Lauryl Sulfate or Monolaurin. Approximately 30 lbs of raw beef cutlets were made on the tenderizer each day of the tests. The tenderizer parts were labeled part 1 and part 2. ...

Abstract

The invention relates to cleaning and food processing aide applications whereby unique compositions of GRAS or food additives were developed to assess the effectiveness of cleaning procedures at various stages of the processes and to assess the delivery and adherence of food processing aides. Employing such solutions to clean and / or sanitize processing equipment provides a method to evaluate and enhance the effectiveness of procedures used to remove the respective fluorescent detergents, sanitizers or organic residues from equipment or niches and reduce contamination. Similar compositions were developed for assessing processing aide food surface coverage, contact time and adherence. In addition, unique compositions were invented that increase processing aide coverage and adherence. Quantification of the presence or absence of the fluorescent GRAS or food additive compositions produces results for validation, monitoring and / or verification of food safety intervention procedures / processes.
