110, 120, 130, 140, 150‧‧‧ steps

FIG. 1 is a flowchart showing a manufacturing process of a chocolate crayon according to an embodiment of the present invention.

Hereinafter, the present invention will be described more specifically with reference to the following examples. In addition, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the preparation amount is expressed on a weight basis.

In the present invention, the chocolate crayons include natural beeswax, cocoa butter, stearic acid, soybean oil, carnauba wax, edible calcium hydroxide and natural pigments.

Based on the total amount of chocolate crayons, the chocolate crayons contain 40% to 80% by weight of natural beeswax, 1% to 40% by weight of cocoa butter, 1% to 20% by weight of stearic acid, and 5% to 30% by weight of soybean oil. %, Carnauba wax 0.5% to 5% by weight, edible calcium hydroxide 10% to 40% by weight, and natural pigments 2% to 30% by weight.

Natural beeswax, as an animal solid wax collected from a honeycomb by a heat-pressing method or a solvent extraction method, is an adhesive amorphous substance. The main components of beeswax are palmityl palmitate and wax acid. Beeswax has the following characteristics: melting point is 62 ° C to 63 ° C, specific gravity is 0.961 to 0.973, refractive index is 1.456 to 1.459, saponification value is 86 to 93, and iodine value is 8 to 14. In the present invention, the natural beeswax is edible beeswax.

Natural beeswax is an additive used to achieve the aggregation and coloration of natural pigments and other additives as pigments. It has the effect of increasing melting point and moisturizing during use, and helps to uniformly disperse the constituent components.

Cocoa butter is a fat obtained from the core of cocoa fruit by a pressing method, and the constituent components are palmitic acid, stearic acid, oleic acid, and the like. Cocoa butter has a melting point of 28 ° C to 36 ° C, a saponification value of 190 to 200, an iodine value of 5 to 40, and the constituent fatty acids are palmitic acid, stearic acid, oleic acid, and the like.

When a crayon is manufactured using only natural beeswax, the crayon becomes stronger and the crayon becomes easily broken. However, by making a crayon by containing cocoa butter, the intensity can be adjusted to prevent breakage during the production of the crayon or when using the crayon, and to enhance the coloring function of gently painting to the colored surface. In addition, by containing cocoa butter, the crayons can have a chocolate odor, and can be made closer to food.

Stearic acid is a saturated higher fatty acid with a carbon number of 18. It is widely contained in animal and plant fats or phospholipids in the form of an ester with glycerin, and is a fatty acid having the largest amount of natural existence. The chemical formula is C ₁₈ H ₃₆ O _2. It is white leaf-like crystals at room temperature. The molecular weight is 284.48 g / mol, the melting point is 71 ° C to 71.5 ° C, the freezing point is 69.4 ° C, the boiling point is 383 ° C, and the density is 0.94g / cm ³ .

Stearic acid plays a similar role to natural beeswax, but it can form a crayon stronger than natural beeswax, so it plays a role of preventing shrinkage during the final process, that is, the forming process.

Soybean oil is a semi-dry oil extracted from soybeans (18% to 20%). Soybeans are mainly produced in the United States and South America, and most of them are used as raw materials for oil extraction. The main ingredients are mixed glycerides of linoleic acid, oleic acid, palmitic acid and hypolinolenic acid. The blended soybean oil is yellow-brown and has an unpleasant odor. Therefore, the refined soybean oil is reconstituted and consumed. The refined oil is light yellow, odorless, and tastes mellow, and is consumed most as an edible oil.

Soybean oil is added during the manufacture of the crayon, so that it can be softly colored when used after manufacture, and the crayon contains a certain amount of oil to play a role in uniformizing the quality until the product is used up.

Carnauba Wax is a wax obtained by refining from leaves and buds of the palm family plant Carnauba. Carnauba wax is a natural wax that is light yellow to light brown powder, flakes, or hard and easily pulverized pieces. Partially soluble in boiling alcohol, soluble in chloroform and ether, but insoluble in water. It should have a specific gravity of about 0.997 and a melting point of 80 ° C to 86 ° C. The allowable daily intake (ADI) is 0.0mg / kg to 7.0mg / kg, and is used as a coating agent for sugars.

Carnauba wax hardens the crayon and works with natural beeswax to increase the melting point of the product to the limit temperature of 60 ° C during use or distribution.

Calcium hydroxide is a colorless crystal that is hardly soluble in water, that is, Ca (OH) ₂ . Also known as slaked lime. The aqueous solution is called lime water and the suspension is called lime milk. In addition, the aqueous solution absorbs carbon dioxide in the air and causes white turbidity of calcium carbonate. When water acts on lime (calcium oxide CaO), it generates intense heat and forms calcium hydroxide. Calcium hydroxide is used as a low-cost neutralizer for industrial alkalis, corrosives, and acid soils, but it refers to industrial calcium hydroxide. In the present invention, edible calcium hydroxide used as a food additive is used.

Calcium hydroxide, together with natural pigments, makes the base color, that is, the white hue more vivid, improves the texture of the product, and facilitates coloring.

Natural pigments are natural pigments obtained by automatic plants. In one embodiment of the present invention, the natural pigments include all natural pigments obtained from animals or plants. For example, the natural pigment may include strawberry powder, blueberry powder, green tea powder, gardenia powder, cuttlefish juice, purple potato powder, and the like.

Natural pigments play a role in determining the color of the crayon.

As described above, in the present invention, since the ingredients of the chocolate crayon include food additives and natural pigments, a crayon that is completely harmless to the human body is provided.

FIG. 1 is a flowchart showing a manufacturing process of a chocolate crayon according to an embodiment of the present invention.

Referring to FIG. 1, step 110 is a first stirring process to heat and melt natural beeswax, stearic acid, carnauba wax, and soybean oil. Based on the total amount of chocolate crayons, 40% to 80% by weight of natural beeswax, 1% to 20% by weight of stearic acid, 0.5% to 5% by weight of carnauba wax, and 5% to 30% by weight of soybean oil . In this step, it is preferred to heat and melt the natural beeswax, stearic acid, carnauba wax and soybean oil at about 90 ° C.

In the case of the first stirring process, since the melting point of carnauba wax is high, it can be homogeneously mixed with the remaining raw materials only by heating in advance and homogenizing to a liquid phase by stirring. Therefore, it is first heated at about 90 ° C.

Step 120 is a second stirring process, and the product in the first stirring process, that is, the melt and cocoa butter, edible calcium hydroxide, and natural pigments are heated to perform melting and stirring. Based on the total amount of chocolate crayons, it contains 1% to 40% by weight of cocoa butter, 10% to 40% by weight of edible calcium hydroxide, and 2% to 30% by weight of natural pigments. In this step, it is preferred that the melt, cocoa butter, edible calcium hydroxide, and natural pigments in the first stirring process be heated at about 80 ° C. for melting and stirring.

In the case of the second stirring process, the natural pigment may change the hue at high temperatures, and the cocoa butter may crystallize at high temperatures, preventing the homogeneous display of the hue. Therefore, it is lower than that of the first stirring process. The temperature is about 80 ° C, which melts cocoa butter, edible calcium hydroxide and natural pigments.

Step 130 is a dispersing process. The melted product, which is the product of the second stirring process, is cooled to solidify and disperse. After the molten material in the second stirring process is cooled with cooling water, it is put into a 3-roll mill (3-Roll Mill) to perform a pulverization or dispersion process.

The three-roll mill is a device that homogenizes the sample by passing the sample through a small gap between the horizontally placed rollers. The three adjacent rollers are rotated to apply pressure and shear force to the sample to obtain the effects of mixing, crushing and dispersing.

The particles of the powder raw material are uniformly dispersed through a pulverization or dispersion process, thereby being easier to melt. In the case of natural pigments, the size of the particles is not uniform, and color development or coloring is facilitated by minute pulverization.

Step 140 is the third stirring process, and the product obtained through the pulverization process is melted again. In this step, the pulverized product is preferably melted between 80 ° C and 85 ° C.

The third stirring process is the final process before being put into the molding machine, that is, the process of injecting in the liquid state in order to be put into the molding machine, so that the above-mentioned pulverized product is melted, and in order to prevent the cocoa butter protein or natural pigments from being deformed, it is 80 From about ℃ to about 85 ℃, it is completely made into liquid phase.

Step 150 is a molding process. After cooling the melted product that is the product of the third stirring process, it is put into a molding machine to produce a crayon, which is the final product.

So far, the present invention has been described focusing on the preferred embodiments. Those having ordinary knowledge in the technical field to which the present invention pertains should understand that the present invention can be implemented in a form deformed within a range not departing from the essential characteristics of the present invention. Therefore, descriptive The point of view considers the disclosed embodiments rather than a limiting point of view. The scope of the invention is defined by the scope of the patent application, not by the above description, and should be construed as including all points of difference within the scope equivalent thereto.
