Definitions

  • the present invention relates to stable, preferably clear, aqueous food cleaning compositions, articles of manufacture, and/or method of use, comprising: solubilized, uncomplexed cyclodextrin; cyclodextrin compatible surfactant; optionally, cyclodextrin compatible antimicrobial active; optionally, hydrophilic perfume providing improved acceptance; or mixtures thereof.
  • cyclodextrin compatible means that the cyclodextrin and the other material, or active, do not substantially interact so as to eliminate the ability of cyclodextrin to absorb odor and other undesirable organic molecules, or the desired effect of the material or active.
  • the food cleaning composition is designed to remove and/or eliminate undesirable materials, such as soil, organic residue materials such as pesticides, odors caused by a broad spectrum of organic odoriferous materials, on food products and/or food contacting surfaces, such as produce, fruits and vegetables, meat, poultry, fish and other seafoods, food preparing surfaces and/or equipment, such as cutting board, countertop, pots and pans, food containers, and the like.
  • undesirable materials such as soil, organic residue materials such as pesticides, odors caused by a broad spectrum of organic odoriferous materials
  • food products and/or food contacting surfaces such as produce, fruits and vegetables, meat, poultry, fish and other seafoods, food preparing surfaces and/or equipment, such as cutting board, countertop, pots and pans, food containers, and the like.
  • the food cleaning composition preferably remain shelf stable for a substantial period of time.
  • Typical examples of such chemical residues are Azinphos- methyl (insecticide for apples, peaches), Benomyl (fungicide for apples, peaches, tomatoes, cucumbers, broccoli, beans), Captan (fungicide for apples, peaches, cucumbers), Chorothalonil (fungicide for tomatoes, carrots, beans, cucumbers, broccoli) Chlorpropham (sprouting inhibitor for potatoes), Dicloran (fungicide for peaches), diphenyl amine (screw worm repellant and post harvest fungicide for apples), Folpet (fungicide for tomatoes), Iprodione (fungicide for peaches, grapes), Linuron (herbicide for carrots), Permethrin (insecticide for lettuce), thiabendazole (fungicide and nematocide for bananas, potatoes, apples) and Vinclozolin (fungicide for grapes, strawberries).

  • Antimicrobial preservatives useful in the present invention include biocidal compounds, i.e., substances that kill microorganisms, or biostatic compounds, i.e., substances that inhibit and/or regulate the growth of microorganisms.
  • Preferred antimicrobial preservatives are those that are water-soluble and are effective at low levels because the organic preservatives can form inclusion complexes with the cyclodextrin molecules and compete with the organic residue molecules for the cyclodextrin cavities, thus rendering the cyclodextrins ineffective as organic residue removing and/or odor controlling actives.

These types of preservatives have a lower affinity to the cyclodextrin cavity, at least in the aqueous phase, and are therefore more available to provide antimicrobial activity.
  • Preservatives with a water-solubility of less than about 0.3% and a molecular structure that readily fits into the cyclodextrin cavity have a greater tendency to form inclusion complexes with the cyclodextrin molecules, thus rendering the preservative less effective to control microbes in the cyclodextrin solution.

  • Electrostatic sprayers impart energy to the aqueous food cleaning composition via a high electrical potential. This energy serves to atomize and charge the aqueous food cleaning composition, creating a spray of fine, charged particles. As the charged particles are carried away from the sprayer, their common charge causes them to repel one another. This has two effects before the spray reaches the target. First, it expands the total spray mist. This is especially important when spraying to fairly distant, large areas. The second effect is maintenance of original particle size. Because the particles repel one another, they resist collecting together into large, heavier particles like uncharged particles do. This lessens gravity's influence, and increases the charged particle reaching the target.

  • the present method improves removal of such pesticides by making them easier to remove. Since pesticides are applied while the produce is still in the field, more complete removal when the produce is picked will improve the produce for the final consumer.
  • Some other actives such as some fungicides and sprouting inhibitors and growth regulators are treated after harvest and before packaging, it is desirable to remove them at the point of consumption, e.g., in the consumer's home or at the food preparation areas of restaurants and cafeterias.
  • Such large scale cleaning which uses a non-manually operated sprayer to dispense the compositions of the present invention is also very useful for commercial and/or institutional food serving facilities such as restaurants and cafeterias to clean a large amount of fresh fruits and vegetables to serve customers with cleaner and safer food.
  • the cyclodextrin solution which contains, e.g., surfactant and/or antimicrobial compound, etc.
  • An effective amount means an amount sufficient to remove soils and absorb unwanted materials to the point that consumption by humans is safer and/or more desirable. Distribution can be achieved by using a spray device, a roller, a pad, etc. Soils and other unwanted organic residues can also be removed by dipping the food products or equipment into a bath of the compositions of the present invention.
  • the present invention also encompasses the method of spraying an effective amount of cyclodextrin solution onto food preparation surfaces such as countertops, cutting boards, and food containers.
  • the present invention relates to the method of spraying a mist of an effective amount of cyclodextrin solution into and/or onto major household appliances including, but not limited to: refrigerators, freezers, ovens, microwave ovens, dishwashers etc., to remove unwanted residues and/or malodor. Unwanted residues can result when, e.g., one sprays the area with consumer products containing chemicals to kill bugs.
  • the presence of the surfactant promotes spreading of the solution and the antimicrobial active provides improved odor control as well as antimicrobial action, by minimizing the formation of odors. Both the surfactant and the antimicrobial active provide improved performance and the mixture is especially effective.
  • Perfume compositions that are used herein are as follows: Perfume A - Citrus Odor
  • compositions are prepared by mixing and dissolving the ingredients in waterto form clear solutions.
  • compositions of the above Examples are sprayed onto soiled produce, e.g., fruits and vegetables such as apples, grapes, peaches, potatoes, lettuce, tomatoes, celery, and the like, using a blue inserted Guala® trigger sprayer, available from Berry Plastics Corp , with light scrubbing as may be required
  • soiled produce e.g., fruits and vegetables such as apples, grapes, peaches, potatoes, lettuce, tomatoes, celery, and the like
  • a blue inserted Guala® trigger sprayer available from Berry Plastics Corp , with light scrubbing as may be required
  • the produce is then rinsed in tap water to remove the unwanted materials
  • compositions of the above Examples are sprayed onto protein foods such as defrost meat, stored fish and seafood, and the like, that have developed some off odor, using a cylindrical Euromist II® pump sprayer available from Seaquest
  • Dispensing with light scrubbing as may be required They are then rinsed in tap water to obtain fresher foods with low off odor
  • compositions of Examples I, IV, VIII, and IX are sprayed onto large stainless steel trays that previously are used to marinate chicken quarters, using a rechargeable battery-operated Solo Spraystar sprayer, with scrubbing as may be required The treated trays are then rinsed off in tap water with scrubbing as may be required, let dry, and are ready to be reused
