Validation of a Simulated Commercial Frying Process

2018-12-11Experimental and statistical designs This research was divided into the following three studies: (1) validation of frying as a kill-step to inactivate a 7-serovar Salmonella cocktail in donuts during frying using 375F (190 6C) oil temperature for 2 min (2) determination of the internal temperature profile pH and a w of donuts during frying and (3) determination of D- and z-values of

Although the kill-step validation procedures recommended by the FDA are time-consuming the procedures are fairly straightforward and can be accomplished by experienced microbiologists and statisticians who have access to containment and laboratory facilities as well as commonly used data analysis applications such as Excel

3 5 1 Ensuring the type of validation requirements and experi-ments conducted are appropriate for final application of the method 3 5 2 Ensuring the validation report is completed and issued in a timely fashion 3 5 3 Reviewing and approving the final validation report to confirm that the analytical method is suitable for its intended use 74

A kill step validation study should be designed and tested for "worst-case conditions" such as lowest oven temperature fastest belt speed lowest zone temperature coldest spot possible shortest time exposed maximum load per batch lowest concentration lowest and highest relative humidity lowest moisture content highest fat content etc

Validation of the baking process as a kill

2017-6-5While baking is considered to be an effective kill-step in controlling foodborne pathogens in bakery products formal scientific validation of the diversity of commercial baking processes for the inactivation of pathogens has not been thoroughly studied (Lathrop et al 2014 Lopez 2014)

2 5 2 Critical limit validation - kill step revalidation question - posted in SQF Food: SQF 2 5 2 states that critical limits must be scientifically validated and subsequently re-validated on an annual basis We employ a kill step during our cooking process to eliminate potential salmonella which was validated to a 6 log reduction from data collected in a lab trial last year

A kill-step – or the addition of heat – can eliminate harmful pathogens such as Salmonella Scientific proof However according to Lakshmikantha Channaiah director of Microbiology at AIB International there was a lack of scientific proof that all pathogens had been eliminated until the development of the Bakery Process Kill Step

2020-6-29Kill-step Validation in Food Quality Control Food quality control is based on hard evidence and scientific proof is needed in kill-steps Most food products have a kill-step at the point of production but there is a need for a validation procedure that ensures safety For this validation to be successful it needs: Diverse expertise

Thus a true validation of a produce wash-and-sanitation system should be how many bacteria viruses parasites and fungi are removed off the produce commodity and then how many of each are killed when in the wash water thus the kill step may probably be a two-step process Example steps in a produce wash-and-sanitation system:

For the past 18 months the company has been working on a set of methodologies to validate the kill step in the oat kiln process testing salmonella in particular But Paul Young senior process authority at PepsiCo Europe said this had been no easy task because the validation step faced a

For validation of the chamber the usual number of temperature measuring points is five for each shelf – one in each corner plus one in center Usually the cross shelf stability (homogeneity) required is 0 5C to 1C and shelf-to-shelf variation is 1C to 2C As freeze dryers are often equipped with 10

Lyophilization Validation: A Regulatory Perspective

2012-3-23Pasteurization Cycle Validation Most of us quite reasonably associate the pasteurization process with the problem of making milk safe to drink Fewer of us are aware of how high a microbial load raw milk actually has when it comes from the dairy cow A five log heat treatment would therefore kill 99 999 percent of the microbial
