Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety of disodium 5′‐inosinate (also known as inosine monophosphate, IMP) produced by Corynebacterium stationis KCCM 80235 as a sensory additive, functional group flavouring compounds, for all animal species. In 2022, the FEEDAP Panel issued an opinion on the safety and efficacy of the product. In that assessment, the Panel could not conclude on the safety of the additive for the target species, consumers, users and the environment due to uncertainties on the genetic basis of the streptomycin resistance of the production strain C. stationis KCCM 80235 and on the possible presence of its recombinant DNA in the final product. The applicant provided supplementary data which elucidated the genetic basis of the streptomycin resistance of the production strain and excluded the presence of its DNA in the final product. Therefore, the FEEDAP Panel concluded that IMP produced by C. stationis KCCM 80235 is safe for the target species, consumers, users and the environment. The FEEDAP Panel reiterated its previous concerns on the safety for the target species when using IMP in water for drinking due to hygienic reasons. [ABSTRACT FROM AUTHOR]

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of disodium 5'‐inosinate (IMP) produced by fermentation using Corynebacterium stationis KCCM 80235 as a sensory additive (flavouring compound) in feed and water for drinking for all animal species. The production strain is genetically modified, and it is resistant to streptomycin. No viable cells were detected in the final product. However, uncertainties remained on the genetic basis of the streptomycin resistance and on the possible presence of recombinant DNA from the production strain in the final product. Therefore, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) could not conclude on the safety of the additive for the target species, consumers, users and the environment. Moreover, the FEEDAP Panel reiterated its previous concerns on the safety of the use of IMP in water for drinking due to hygienic reasons. The Panel concluded that the additive is efficacious to contribute to the flavour of feed and water for drinking. [ABSTRACT FROM AUTHOR]

Abstract Following a request from the European Commission, the Panel on Additives and Products or substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of disodium 5′‐inosinate (IMP) produced by fermentation using Corynebacterium stationis KCCM 80161 when used as a sensory additive (flavouring compound) in feed and water for drinking for all animal species. The production strain is not genetically modified. Viable cells of the production strain were not detected in the final additive. The additive does not give rise to any safety concern regarding the production strain. IMP produced using C. stationis KCCM 80161 is considered safe for the target species, for the consumer and for the environment. IMP produced using C. stationis KCCM 80161 is considered not toxic by inhalation, not irritant to skin or eyes and not a dermal sensitiser. The FEEDAP Panel expressed reservations on the use of the additive in water for drinking due to concerns on its impact on the hygienic conditions of the water. The Panel concluded that the additive is efficacious to contribute to the flavour of feed.

Acrolein (ACR) is a highly active, simple unsaturated aldehyde found in various high-temperature processed foods. Its long-term accumulation in the human body increases the risk of chronic diseases. Animal and plant foodstuffs are rich in disodium 5'-guanylate (GMP) and disodium 5'-inosinate (IMP), which are authorized flavor enhancers. Herein, we used liquid chromatography with tandem mass spectrometry to explore the reaction-active kinetics and pathway of the interaction between GMP/IMP and ACR and validated it in roasted pork patties. Our results suggested that GMP and IMP could efficiently eliminate ACR by forming ACR adducts (GMP-ACR, IMP-ACR). In addition, IMP exhibited a higher reaction rate, whereas GMP had a good trapping capacity at a later stage. As carriers of GMP and IMP, dried mushrooms and shrimp exhibited an effective ACR-trapping ability in the ACR model and roasted pork patty individually and in combination. Adding 10% of dried mushroom or shrimp alone or 5% of dried mushroom and shrimp in combination eliminated up to 53.9%, 55.8%, and 55.2% ACR in a roasted pork patty, respectively. This study proposed a novel strategy to eliminate the generation of ACR in roasted pork patties by adding foodstuffs rich in GMP and IMP.

The flavours included in this assessment are widely present in nature as the building blocks of DNA and RNA. In the absence of any information on the microbial strains or substrates used for the production of the additives, and with little information on the manufacturing process, the FEEDAP Panel is unable to ascertain whether the manufacturing process introduces any safety concerns. Disodium 5'-guanylate and disodium 5'-inosinate and their mixture are considered to be safe for the target animals and the consumer. However, considering the lack of information on the production process, these conclusions apply only to the compounds 'per se' and their extrapolation to any feed additive containing these compounds is not possible. In the absence of any data related to hazard to the user, it would be prudent to regard disodium 5'-guanylate and disodium 5'-inosinate and their mixture as potentially hazardous to workers by skin or inhalation exposure. The compounds under assessment are naturally present in feed materials; therefore, no risk to the safety for the environment is foreseen. Since these compounds are used in food as flavourings, and their function in feed is essentially the same as that in food, no further demonstration of efficacy is necessary. [ABSTRACT FROM AUTHOR]
