Definitions

  • the present invention relates to a washing formula suitable for use with foodstuffs, which is applicable to washing fruits, vegetables, edible roots or the like foodstuffs for removing pesticide residues in an effective and safe fashion.
  • fruits is conceived to include various types of berries as well.
  • the peel or skin of fruits and vegetables protects the inner portion thereof from the evaporation of water and the effects of oxygen, which impair the taste, nutritive value, and vitamin content thereof. If it is necessary to peel the products, it is most preferable that such products be used immediately or be put in a freezer.
  • the best storage wrapping for fruits and vegetables is their very own peel or skin.
  • the skin of several fruits and vegetables contains plenty of ceraceous or waxy substances which are soluble in fat.
  • the organic pesticides or preservatives are also soluble in fat and, hence, impregnate effectively in the surface of these products. In these cases, washing with plain water is not sufficient to remove pesticide residues.
  • the pesticides or preservatives which contain surface-active agents, are in aqueous dilutions capable of penetrating and spreading everywhere in the skin layers.
  • the surface-active agents accepted in food and pharmaceutical industries include esters of sorbitan derivatives of fatty acids, e.g. Span 20, and the ethoxylated derivatives thereof, e.g. Tween 80.
  • Edible oils contain abundant amounts of triglycerides, which due to unsaturated fatty acids are liquid at room temperature (+ 20°C). Those are nutrients absorbed from the alimentary canal and decomposing in the organism first into fatty acids and glycerol. Due to the oily nature thereof, the vegetable oils often function as a solvent for hydrophobic, water-insoluble substances.
  • triglycerides themselves are fats and not miscible in water, the hydrolysis products thereof, fatty acids, mono- and diglycerides, can be miscible in water. They also have surface-active characteristics, especially if the mixture is neutral or alkaline. In acidic conditions, they function as oil-containing solvents.
  • the adjustment of acidity in foodstuffs can be effected by using citric acid, which is also
  • a washing formula suitable for use with foodstuffs and intended for washing fruits, vegetables, and edible roots and which is characterized by containing surface-active agents and wax-dissolving agents.
  • the wax-dissolving agent comprises preferably some vegetable-oil based substance, e.g. a vegetable-oil based ester, such as triglyceride, and/or the hydrolysis product of an ester.
  • Triglyceride is obtained e.g. from sunflower, turnip rapeseed, rapeseed, or soybean oil or mixtures thereof.
  • the concentration of triglycerides in the washing formula is 0 - 50 %, preferably 2 - 20 %.
  • the hydrolysis products of triglycerides are prepared by an alkali, acid, or enzymatic treatment of triglycerides to effect a complete or partial hydrolyzation thereof.
  • the hydrolysis products of triglycerides have a concentration in the washing formula within the range of 0 - 100 %, preferably 20 - 40 %.
  • the surface-active agent comprises preferably a sorbitan-derived substance, which is the ester of a fatty acid and sorbitan or an ethoxylated derivative thereof, wherein the fatty acid has an average carbon chain length within the range of 8-20 carbons.
  • the sorbitan-derived surface agent has a concentration within the range of 0 - 100 %, preferably 30 - 60 %.
  • the washing formula of the invention preferably contains an acid which particularly enhances the removal of heavy metal residues, such as copper compounds, from the surface of products.
  • the acid comprises preferably tetra- acetic acid, e.g. ethylenediamine tetra-acetic acid.
  • the washing formula may contain also isopropanol, e.g. about 0,1 - 5 %, which functions a.o. as an anti-precipitant and contributes to the penetration of the washing medium into wax.
  • the washing formula of the invention is used as a solution diluted in water, said formula having a concentration in aqueous solution of about 1 % to about 10 %, preferably from about 2 % to about 5 %.
  • Another object of the present invention is the use of a food-compatible washing formula, containing surface-active agents and wax-dissolving agents, for washing fruits, vegetables, and edible roots in an aqueous solution, wherein the washing formula has a concentration of about 1 % to about 10 %, preferably from about 2 % to about 5 %.
  • the washing formula is used e.g. by blending the same in water in a sink or washbowl.
  • the washing formula can also be used e.g. by spraying a pre-mixed aqueous solution.
  • the washing formula of the invention is non-toxic and contains biodegradable substances and removes effectively pesticide or preservative residues, nor does it itself leave other harmful agents in the product.
  • Table 1 shows a few examples of washing formulae of the invention.
  • the table discloses various trade names, whereof Arlacel and Tween 80 are various sorbitan oleates.
  • Tween 20 is one sorbitan laurate and Trilon B flussig contains ethylenediamine tetra-acetic acid and tetrasodium salt in water.
  • the agents shown in the table have concentrations preferably within the following ranges: Arlacel 28-67 %, preferably about 45-50 %; Tween 80 6-20 %, preferably about 10 %, Tween 20 0-20 %, preferably about 1-5 %, more preferably about 2 %; a fatty acid mixture about 10-45 %, preferably about 25-30 %, more preferably about 28 %; a vegetable oil about 1-13 %, preferably about 5 %; Trilo ⁇ Flussig about 3-22 %, preferably about 5-10 %, more preferably about 8 %.
  • Patent Blue contained in the compositions (about 0,001 %) contributes to appearance and colour, water (about 0,08 % - about 1 ,1 %) to consistency, and cotric oil (about 0,175 %) to scent; these have no effect on washing power.
  • washing solution containing a combination 1 of table 1 was tested in the customs laboratory on mandarin oranges which, on the basis of preliminary testing, contained residues in amounts sufficient in terms of testing. Equal numbers of mandarins were included in two samples (12 pieces/sample).
  • the analyzing method was TLAB-PE1 Modif. AOAC 985.22, 1990.
  • the gas chromatographic determination of pesticides from fruits, berries, vegetables, and grains (a method accredited by FINAS).
  • Pesticides applied before harvest Methidathion 0,20 mg/kg 0.09 mg/kg Malathion 0,16 mg/kg 0,06 mg/kg Chlorpyrifos 0,14 mg/kg 0,08 mg/kg Dimethoate 0,03 mg/kg 0,02 mg/kg
