Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is useful for preparing eggs, meat, etc. in business or mining households using heated iron plates, open ovens, microwave ovens, etc.

This composition relates to a spray-type blended edible oil aerosol composition that can prevent food from sticking to a heated iron plate or heated metal grid when cooking fish, bread, okonomiyaki, etc. You can prevent food from sticking to the griddle or griddle by applying it to the griddle or griddle.

(Prior Art) Conventionally, the simplest method for applying cooking oil to cooking utensils, such as iron plates and wire meshes, is to soak absorbent cotton in cooking oil and apply it by hand to the iron plates, wire meshes, etc. Also, to improve the mold release properties of cooked foods.

A method of incorporating paraffin, silicone oil, etc. into edible oil has also been used. However, mineral substances such as paraffin and synthetic substances such as silicone are no longer used for human health reasons.

It has become common practice to include natural lectins in edible oil. However, applying it to heated metal objects by hand carries the risk of burns, and it is often difficult to apply it evenly, so spraying is used industrially to ensure uniform application.

An aerosol type is suitable for home use or small business use. Moreover, since the main component of edible oil is triglyceride, it has a viscosity of about 70 to 100 cps at room temperature, and when solid lecithin is contained, the viscosity increases further.
Even if LPG or carbon dioxide gas is used as a propellant, it cannot be made into a spray.

For this reason, a method of adding alcohol to lower the viscosity and making it into a spray is disclosed in JP-A-51-133459 and JP-A-56.
-144052, etc. However, all of these methods use alcohol to lower the viscosity, which increases flammability and is extremely dangerous in areas where fire is used.Other methods include emulsifying cooking oil containing lecithin. The resulting oil-in-water emulsion is used as an aerosol stock solution, and LPG is used as a propellant in nine aerosol formats.

In this aerosol type, LPG is dissolved and dispersed in a liquid form in an emulsion in an aerosol container.

The propellant is used in an amount of about lθ% based on the stock solution, and when the contents are injected, the @VC liquefied gas is vaporized and a good spray can be obtained due to the 72 threading phenomenon at that time. However, since this spray contained vaporized LPG, it was extremely dangerous to use it near open flames.

(Problems to be Solved by the Invention) Edible oil products are often used in a heated state during use of fire for V4 burial, and there are many chances that they will be stored. It is preferable that the oil is non-flammable.For this purpose, it is possible to emulsify the edible oil with water to suppress flammability and lower the viscosity to make it sprayable. It is also desirable to use a non-flammable, non-toxic, and highly stable gas for the injection gas, rather than a flammable one like LPG. Nonflammable gas is CFC 12,114°1 as liquefied gas.
There are 1st class, but these are synthetic products and are not allowed to be used in food products. Compressed gases include nitrogen gas, carbon dioxide gas, etc., but carbon dioxide gas is a composition containing water. The water dissolves in the water and becomes carbonated water, the gas pressure decreases, and the acidic taste of the carbonated water becomes sour, causing corrosion of the aerosol volume and making it unusable.

Nitrogen gas is non-toxic, tasteless, non-flammable, and highly stable; however, since nitrogen gas hardly dissolves in the contents and is sealed in the container in a compressed state, the spray can be formed using only the nitrogen gas pressure. be exposed. Therefore, it is necessary to maintain the viscosity of the contents at a low value at all times.

(Mean J!IIt-Means for Solving) The present invention has been made to solve the problems of the prior art as described above.According to the present invention, lecithin t
-0.5~5.0% Edible oil contains L~5% of emulsifiers such as sorbitan fatty acids, fatty acid monoglycerides, polyglycerin fatty acid esters, citric acid monoglycerides, sugar esters, etc., alone or in combination, and a preservative is desired. amount and mix at about 60-80°C to form a homogeneous phase. Add water at the same temperature to this to prepare an oil-in-water emulsion.The appropriate amount of cooking oil is about 20-45%, and the amount of water is 78.5-45%.
．． 1 at 0%. The viscosity range of the composition thus adjusted was 30
The viscosity of the finished emulsion varies depending on the proportion of cooking oil, the type of cooking oil, the emulsifier selection, etc., but in the case of oil-in-water emulsions, the oil When the composition ratio increases and the composition ratio of water decreases, the viscosity of the resulting emulsion increases, and vice versa, the viscosity decreases. When spraying by fully filling 60 to 85% of the volume of the aerosol can with the stock solution and further pressurizing it with two gases to 6 to 10 kg/r, tr*, it depends on the conditions of the nozzle, but generally it is possible to spray. The viscosity is 180 cps or less. lecithin 0.5
% or less and edible oil is less than 20%, which is undesirable because the mold release properties of the cooked product will be poor.The content and viscosity range of lecithin and oil that can be sprayed with nitrogen gas should be within the above range.

The present invention will be explained in more detail with reference to the following examples.

Examples and comparative examples The sample was a chicken egg that contained enough sugar to cause it to burn.

The results of 9 cases of fried eggs using a frying pan spray-coated with the aerosol composition of the present invention are shown below.

The preparation method of the compositions of Examples and Comparative Examples is as follows: Prepare a mixture by mixing edible oil, lecithin and emulsifier in the component proportions shown in the following table, warm it to 70°C, While vigorously stirring with a homomixer, water heated in the same manner to 70°C is added, stirred at that temperature for about 10 minutes, and then gradually cooled.

In Examples and Comparative Examples, soybean salag oil was used as the edible oil, but similar results were obtained with sesame oil, safflower oil, and corn oil.From the results in Table 1, the prepared edible oil aerosol composition according to the present invention has sprayability. .

It can be seen that it is extremely excellent in terms of mold releasability, flavor, coloring, and odor.

Note: Comparative Example 1 uses only edible oil and cannot be filter sprayed.

Comparative Example 2 had poor sprayability.

In Comparative Example 5, the pressure was low and the initial sprayability was good, but the sprayability deteriorated in the middle.

※※) 1 OklI/cm or more violates the High Pressure Gas Control Law.

(Effects of the Invention) Since the composition of the present invention is an aerosol product, it can be easily used by simply pressing the spray button on the aerosol container, and has the advantage of being able to be applied uniformly and effectively to the desired location. It is extremely safe from fire as it is nonflammable as well as gas. Approximately 30cm further from the target application surface.
