Definitions

  • the present invention relates to a process for reducing the level or retarding the outgrowth of bacteria on food and nonfood products by treatment with a composition which includes one or more safe and suitable hops acids or hops acid derivatives or hops resins or hops resin derivatives and one or more surfactants, surface active agents, chelators, antioxidants and/or organic acids. More specifically, the process comprises using as an ingredient or applying to a food surface or a nonfood product a composition comprising beta hops acids and one or more nonionic surfactants, chelators, antioxidants and/or organic acids in order to reduce or eliminate gram positive spoilage or pathogenic bacteria, and especially strains of the harmful pathogen Listeha monocytogenes.
  • gram positive bacteria such as Listeria monocytogenes, Staphlococcus aureus, Bacillus cereus, Clostridium botulinum and the like
  • miscellaneous gram positive spoilage bacteria such as lactobacilli, bacilli, streptomyces, and micrococci species may cause reduction in the shelf life and appeal of processed foods and high moisture consumer care products. Both pathogenic and spoilage bacteria occur most commonly at the surfaces of foods or consumer care ingredients, which come into contact with undesirable bacteria by contamination from environmental sources.
  • hops beta acids in fatty acid containing foods has prevented them from being used commercially as natural anti-microbial agents for control of listeria or other gram positive pathogens. Further, it is unlikely that hops acid activity would prove effective in the water in oil emulsions common among most consumer care products.
  • the ability to tag the hops acids in the aqueous phase of such systems is a property that would dramatically increase their value as anti-microbials in either food or consumer care products containing high oil or fatty acid levels.
  • composition which has as a first component, at least one compound selected from the group consisting of hops acids, hops acid derivatives, hops resins, and hops resin derivatives; and as a second component, at least one compound selected from the group consisting of food grade surfactants, surface active agents, chelators, antioxidants, and organic acids provides excellent antibacterial properties, especially against potentially harmful gram positive bacteria of the Listeria genus and can easily be applied to the foods or consumer products based on oil in water emulsions.
  • One embodiment of the present invention comprises an antibacterial composition
  • an antibacterial composition comprising: (a) a first component having at least one compound selected from the group consisting of hops acids, hops acid derivatives, hops resins, and hops resin derivatives; and (b) a second component having at least one compound selected from the group consisting of food grade surfactants and surface active agents.
  • a composition containing beta hops acids and a food grade surfactant or surface agent which is either a nonionic surfactant, a propylene glycol, or a mixture thereof.
  • the present invention provides a method for reducing, retarding, or even eliminating gram positive bacteria, and especially the Listeria monocytogenes, in food products comprising the step of treating the surfaces of said food product with a bacteristatically or bactericidally effective amount of a composition comprising: (a) a first component having at least one compound selected from the group consisting of hops acids, hops acid derivatives, hops resins, and hops resin derivatives; and (b) one or more food grade surfactants and/or surface active agents.
  • An additional object of the present invention is to provide a novel composition having substantially greater antibacterial properties than previously observed for the individual components of the composition.
  • An additional object of the present invention is to provide a product which is easily applied to all surfaces of a food product which is potentially susceptible to bacterial degradation.
  • a final object of the present invention is to provide a product which can work well under the partitioning conditions of a fat or oil in water emulsion.
  • the present invention provides a novel antibacterial composition and its use in a process for reducing, retarding, or totally eliminating harmful bacteria, preferably from food surfaces.
  • the novel antibacterial composition comprises: (a) one or more hops acids or hops acid derivatives or hops resins or hops resin derivatives or mixtures thereof; and (b) one or more food grade surfactants or surface active agents or chelators, or antioxidants, or organic acids, or mixtures thereof, preferably food grade surfactants or surface active agents or mixtures thereof.
  • the first component of the novel composition is one or more hops acids, or hops acid derivatives, or hops resins, or hops resin derivatives, or mixtures thereof.
  • the bitter acids component of the hops used in beer making and particularly the beta-acids have now been found to be useful as bactericides in food products.
  • the most prevalent groups of bitter acids found as components of hops are the alpha-acids and the beta-acids, also referred to as humulones and lupulones, respectively. Both contribute bitterness to beer, but the alpha-acids are much more intense in this regard than the beta-acids.
  • a by-product of the operation is a product which contains approximately 61 weight percent beta-acids, the remainder consisting essentially of hops resins. This by-product can be standardized with malto-dextrin or other food grade carrier, spray-dried, and used as an antibacterial food ingredient.
  • a preferred beta hops acids component is commercially available as a natural flavor extract containing 1 weight percent beta hops acids.
  • the alpha-acids contained in hops are commonly known as humulone, cohumulone and adhumulone, while the beta-acids contained in hops are commonly known as lupulone, colupulone and adlupulone.
  • Derivatives of the hops acids or hops resins which have demonstrated antibacterial properties such as hexahydrocolupulone and tetrahydroisohumulone, as disclosed in U.S. Patent No. 5,455,038, are specifically contemplated for use in association with the present invention.
  • Also considered as specifically contemplated for use in association with the present invention is the use of the acid salt forms of the hops acids or hops resins.
  • the hop acid or resin or derivative thereof is added to the food product in amounts between about 0.1 to about 50 ppm (by weight of solution used for treatment), more preferably between about 0.40 to about 20 ppm.

  • surface active agent is intended to also include what is commonly known as a protective colloid.
  • the surfactant employed preferably is a food grade emulsifier with a high hydrophilic lipophilic balance (HLB) value. Such values should range from about 10 to about 16. Suitable emulsifiers preferably have also been approved for use in foods since many of the applications for the present invention reside in the food and drug industries.
  • the emulsifier is selected from the group consisting of polyoxyethylene sorbitan esters, sorbitan esters, monoglycerides, diglycerides, lecithin, polyglycerols, sodium stearoyl-2-lactylate, stearyl-2-lactylic acid, polyoxystearates, acetylated monoglycerides and mixtures thereof.
  • sorbitan esters and polyoxyethylene sorbitan esters are the emulsifiers of choice. The above list is considered only a representative listing as the present invention contemplates the use of any food grade surfactant .
