TL;DR: A method for inhibiting the growth of bacteria in raw or processed meat products having a pH between about 6.0 and 6.5 stored at above freezing temperatures using an inorganic propionate salt which extends the shelf life of the meat is described in this article.
Abstract: A method for inhibiting the growth of bacteria in raw or processed meat products having a pH between about 6.0 and 6.5 stored at above freezing temperatures using an inorganic propionate salt which extends the shelf life of the meat is described. The salt is preferably sodium propionate or calcium propionate and is used in an amount less than about 1% by weight and preferably between about 0.05 and 0.5 percent by weight of the meat such that no flavor is imparted to the meat. Preferred dried compositions containing a bacteriocin from Pediococcus acidilactici and a propionate salt are also described.

TL;DR: In this paper, the authors proposed an additive consisting of ferrous sulfate, sodium propionate or potassium propionates and copper sulfate in the weight ratio of content of the feed additive of (2-0.75)/(2-1)/1.
Abstract: PROBLEM TO BE SOLVED: To obtain the subject additive for feed, having excellent antibacterial power against various bacteria, especially Salmonella, useful for domestic animal, domestic fowl, cultured fish, etc. by including ferrous sulfate, sodium propionate, etc. as active ingredients. SOLUTION: This additive comprises ferrous sulfate, sodium propionate or potassium propionate and copper sulfate in the weight ratio of content of ferrous sulfate/sodium propionate/copper sulfate of (2-0.75)/(2-1)/1.

TL;DR: In this paper, the anodic oxidation of the propionate anion in aqueous solutions of propionic acid at a platinum electrode has been studied in the presence of several organic compounds in order to demonstrate the formation of both propionoxy and ethyl radicals as the reaction intermediates.
Abstract: The anodic oxidation of the propionate anion in aqueous solutions of propionic acid at a platinum electrode has been studied in the presence of several organic compounds in order to demonstrate the formation of both propionoxy and ethyl radicals as the reaction intermediates. One of the following organic compounds was added to each solution: two vinyl monomers (acrylic acid and acrylamide), two alkylbenzenes (toluene and cumene), and two aliphatic alcohols (methanol and isopropanol). The electrooxidation of sodium propionate in the presence of acrylamide resulted in polymerization, which was confirmed to be initiated by the ethyl radical. Acrylic acid, unlike acrylamide, gave no polymers. In this case, both the current efficiency for the formation of carbon dioxide and the yield ratio of ethylene to carbon dioxide were always less than those observed in the absence of acrylic acid. While the addition of alcohols gave no definite results, the addition of toluene or cumene resulted in an appreciable decreas...

TL;DR: In this paper, a method of treating antimicrobial products, dairy products, pharmaceutical products and other products having offensive tastes or odors to remove the off-odors and off-tastes from the products.
Abstract: A method of treating antimicrobial products, dairy products, pharmaceutical products and other products having offensive tastes or odors to remove the off-odors and off-tastes from the products. The method involves exposing a selected commercial grade product that contains a small amount of free acid impurities to an ammonia gas. The ammonia gas reacts with the free acid impurities to convert the free acids into ammonium salts, thereby reducing or eliminating the off-flavor and off-odor of the product. The products to be treated include antimicrobial products selected from the group consisting of sodium benzoate, calcium benzoate, potassium benzoate, sodium diacetate, paraben, niacin, calcium acetate, calcium diacetate, sodium sorbate, calcium sorbate, potassium sorbate, sodium propionate, calcium propionate, potassium propionate and mixtures thereof; dairy products selected from the group consisting of casein, whey, skim milk powder, and calostrum; pharmaceutical products selected from the group consisting of acetaminiphen, aspirin, ibuprophen, dextromethorphan hydrobromide, guaejenesin, paracetamol, and sodium erythorbate; and various other products selected from the group consisting of butylate hydroxy tolulene, polydextrose powder, sodium acid sulfate, and sodium diacetate. The common characteristic of the commercial grades of each of these products is that they contain a small amount of free acid impurities that react favorably with ammonia gas.
