There are many materials working to increase the duration of meat preservation and they are among the biological preservation materials, including many types of bacteria or weeds, and currently the use of marine algae has begun to preserve foodstuffs

Thanks Prof-Dr- Amera Al-Rubeii mam for discussing about the research work on these biological preservatives.

Dear Chinaza Godswill Awuchi sir thank you for adding these permitted additives lists . but i talk about the bio preservatives not the chemical ones.

Lactic acid bacteria. Of special interest are lactic acid bacteria (LAB). Lactic acid bacteria have antagonistic properties which make them particularly useful as biopreservatives. When LABs compete for nutrients, their metabolites often include active antimicrobials such as lactic and acetic acid, hydrogen peroxide, and peptide bacteriocins. Some LABs produce the antimicrobial nisin which is a particularly effective preservative.

For commercial purposes, bacteriophages and their endolysins can be incorporated into food systems in several ways such as spraying, dipping or immobilization, singly or in combination with other hurdles. The phage preparation LMP-1O2 has been subsequently commercialized as "ListShield" Intralyx, Inc. It has been shown to be effective against 170 different strains of "L. monocytogenes", reducing significantly (10 to 1000-fold) the Listeria contamination when sprayed onto ready-to-eat foods, without changing the food general composition, taste, odor or color.

Dear Chinaza Godswill Awuchi sir,

Thanks for your answer.

You can use pediocin, sakacin, natamycin as natural preservation agents.

Dear Fatma Coşkun Topuz

thaks for mentioning these natural preservatives but what about their permissible limits in foods?

Dear Asik Ikbal

Apart from nisin, there are many other bacteriocins that have been demonstrated as antimicrobials. Examples include pediocin, sakacin, reuterin, lacticin, macedocin and colicin. Most of these are gram-positive inhibitors, and in general, they have much narrower antimicrobial spectrums than nisin. Their application in purified form in foods has yet to be approved.

...., nisin is the only bacteriocin so far approved by FDA for food applications. FDA has affirmed that nisin derived from certain strains of Lactococcus lactis subsp. lactis is GRAS for use as an antimicrobial agent in various cheese products such as cheese spreads and process cheese when used at a level that delivers a maximum of 250 ppm of nisin in the finished product (21 CFR 184.1538). Nisin also can be used in meat and poultry at 600 ppm when the meat is fully cooked and used as a component in sauces. Under these conditions, the meat and poultry cannot be more than 50% of the product. Nisin can also be used as a component of meat and poultry soups at a much lower concentration of < 5 ppm of the product formulation. More recently, nisin is allowed to be used in casings at 3.15 mg/lb., and in cooked meat and poultry products at 2.5 mg/lb. [GRAS Notice No. 000065]. In all cases listed here, nisin must be declared on the ingredient statement.

Other bacteriocins including pediocin, sakacin, reuterin, lacticin, macedocin and colicin are yet to be approved with definite permissible limit

Sakacin and natamycin can be used as synthetic chemicals.

thank you Chinaza Godswill Awuchi sir for your valuable inputs.

Natamycin

Natamycin is a natural preservative used as an ingredient in food and pharmaceutical industries. Natamycin, also named Natacyn or Pimaricin, is E235 food additive in EU.

https://sinofoodsupply.com/food-supplier-manufacturer/natamycin/

Natamycin (E235, Natacyn or Pimaricin) is a white or yellowish crystalline powder. Natamycin is slightly soluble in water and almost insoluble in in alcohols, ether, esters, aromatic, aliphatic and chlorinated hydrocarbons.

MicrogardTM, natamycin and Pediocin can be applied.
