Definitions
- the invention relates to a composition for treating raw materials, products, water or production means, particularly in the food processing industry, which composition is prepared from hydrogen peroxide and glyc- 5 erol .
- the invention relates to a method for preparing this composition and a method for treating raw materials, products, water and/or production means, wherein use is made of said composition.
- composition having hydrogen peroxide and glycerol therein, which composition can be used for treating all kinds of substances.
- This European patent application moreover describes devices for per-
- EP-A 0 460 962 is described a method wherein vegetable foodstuffs are sprayed with an aqueous solution which can contain up to 0.025% of an organic peracid. A treatment with aqueous thiosulphate then follows.
- the object of this European patent application is to perform a decontamination an ⁇ 4 to improve the product appearance.
- DE-A-3 806 953 describes a solution for cleaning contact lenses.
- a disinfectant is herein present in the form of hydrogen peroxide. This disinfectant can be combined with a borate, glycerol, amino acetic acid or an acetate or phosphate in order to obtain an isotonic solution.
- waste-water purification installations are usually designed on the basis of the average water quality, the bacteriological impact and effluent norms. Disruptions in production then often result in overload- ing of the installation, whereby it becomes necessary to resort once again to chemicals to comply with production standards. This results in an occasionally unacceptable increase in costs and environmental impact .
- composition according to the invention can be brought without problem into contact with untreated foodstuffs. Possible degradation products of the composition according to the invention are not substances which are foreign to the body or toxic.
- the composition according to the inven- tion will also have a more rapid activity without being aggressive.
- the product herein has a long-lasting main ⁇ taining and protective activity on the shell of the egg. This is attributed to the activating effect deriving from the glycol acid in the solution which thereby has a potentiating effect on organic and bacteriological con ⁇ taminations.
- the product is highly suitable for preserving citrus fruits, flower bulbs, potatoes and other agricultural products, which must be stored for a longer period and protected against fungoid growth and/or bacterial post- contamination/recontamination during storage and trans ⁇ port.
- the objects or materials are preferably treated by spraying the above stated solution under overpressure into the space in which they are situated.
- This method of treatment/conservation is very efficient with a very low consumption of the invented product, since it is used in the gas phase.
- the foodstuff hereby suffers no damage by the ' agent.
- a quantity of the solution is preferably used in the treatment of food products such that 0.1 - 1 g hydrogen peroxide is applied per kg of food product.
- Treatment in the above stated manner takes place in particular at a temperature between 5 and 7°C for about 1 minute to about 0.5 hour, depending on the treatment temperature and the concentration of the solution in the space.
- composition can be prepared from:
- Demineralized water is preferably used as solvent system.
- Glycol acid is mixed with the glycerol before being added to hydrogen peroxide mixed with the glycerol . This is necessary to arrive at a composition with a good activity. This preferably takes place in the following manner.
- the glycol acid is added to the glycerol, this in order to prevent explosive reactions which would result with the addition of glycol acid to a mixture of hydrogen peroxide and glycerol .
- the maximum percentage by weight of glycol acid is 25 gram per kg of final composi ⁇ tion.
- the weight ratio hydrogen peroxide:glycerol lies between 4:1 and 10:1, preferably between 2:1 and 5:1.
- the ratio glycerol:glycol acid preferably lies between 5:1 and 25:1.
- the concentration of hydrogen peroxide in the solution amounts to 10-50%, preferably 25-35%. All per ⁇ centages given in this description are related to the weight of the final composition unless otherwise stated.
- the solution of glycerol (1,26) and the glycol acid 57% can now be added in doses to the hydrogen perox- ide via an inline-mixer, this for early quenching of a reaction so that a maximum of active substance remains in the solution, where active substance would otherwise be lost with a reaction in the mixing pan.
- the storage area for hydrogen peroxide, the conduits and the inline-mixer and mixing pan are cooled by means of a water cooling system.
- the reaction may never have a tempera ⁇ ture increase of more than 0.5°C (in the mixing tank) .
- the whole must remain in the mixing pan for at least 20 minutes to be certain of a homogenous mixture, wherein a temperature of less than 4°C is maintained preferably for a minimum of 10 minutes.
- Storage must take place in non- ransparent and approved packagings, in a cool place and separated from oxidizing products and organic material such as wood, textile, paper and alkaline agents.
- the storage space must be sufficiently cool and ventilated.
- the solution will not decompose to any signifi ⁇ cant extent in brine or seawater owing to the silver chloride present therein. This may even have a catalyzing effect on the solution. It is therefore not inconceiv ⁇ able, if required, for a dose of AgCl to be added to the solution in order to obtain a more intensive activity of the product in some cases, and this only for non-food.
- composition according to the invention can be used involve contact with brine/seawater of 20 degrees Brix or higher.
- the concentration of glycol acid in the composi ⁇ tion according to the invention depends on the quantity of glycerol and hydrogen peroxide. Preferably however, no more than 25 grams of glycol acid is applied per kilogram of composition.
- composition 125 grams of glycerol is applied per kilogram of composition and 5 to 25 grams of glycol acid will be present per kilogram of composi- tion. This may depend on the application and the standard activity on a contamination.
- Quality indication 100, 125, 150, 175 grams of glycerol, of which 125 grams of glycerol per kilogram of product is the most usual.
- the specific gravity of the components is not applicable herein. However, in the case of glycerol the 5 grams of glycol acid is reckoned per kilogram glycerol.
- Glycerol with glycol acid dissolved therein is in the following ratios:
- the ratio of hydrogen peroxide to these mixtures is (hydrogen peroxide 10%, 20%, 25% and 50% solution in water) 9:1, 7:1, 6.7:1, 5.7:1.
- the above-mentioned ratios can be dissolved in water, preferably demineral- ized water.
- A:B as 1:2 A:C as 6.7:1 C:D as 30:1
- A:B as 1.2
- A:C as 5.7:1 C:D as 35:1
