Application of lactic acid on primal beef before production

This is our process. We are a small USDA establishment producing under a Raw Ground HACCP. Our process is as follows… We spray Lactic Acid on beef primal which is mostly Chuck Tenders, within 1-2 minutes the product is placed on an incline conveyor belt approximately 12-16 feet long, the product is dropped into a “Butcher Boy” and is then placed into a grinder. The entire operation takes approximately less than 3 minutes between the times of spray to its first cut in the “Butcher Boy”. Do you have any supporting documentation (studies) indicating a hold/wait time of 1 to 3 minutes after application of Lactic Acid on primal beef before being put into production is not relevant to the effectiveness? We are unable to wait for 20 minutes between application and first cut. If you have any question please feel free to contact me, we look forward to hearing from you.

This is a control Step.  I think I have my answer.
