Example 1 Collection and Washing of Graviola

Gravola collection and washing step is to remove the foreign matter attached to the raw leaves of the gravola by collecting and washing the raw leaves of the gravola. In the step of collecting and washing gravola, the raw gravure leaves can be washed with clean purified water.

Example 2 First Drying Step of Graviola

The first drying step of the gravureola is to dry the washed leaves of the gravureola in a well-ventilated shade. Gravola's first drying step can be carried out in a well-ventilated shady place to prevent chlorophyll breakdown and the gravure's inherent fragrance during sunlight drying. The first drying step is a temperature of 20 to 35 ° C and a humidity of 50 to 80 By drying for 10 to 20 hours in the shade maintained at%, the moisture content of the raw gravure leaves can be maintained at 40 to 50% by weight relative to the total weight of the original gravure leaves. In the first drying step, the moisture contained in the raw gravure leaves is gradually evaporated evenly according to the process conditions so that the unique taste and aroma of gravure can be more easily exhibited. By facilitating penetration and promoting fermentation, the taste and aroma of gravola tea can be enhanced. In the first drying step, the moisture content of the raw graviola leaves can be dried to maintain 40 to 50% by weight relative to the total weight of the original graviola leaves. When the moisture content of the raw graviola leaves is kept below 40% by weight, If the water is excessively evaporated during the subsequent drying and steaming processes, the taste and aroma of the gravure tea produced may be reduced, and water may not be easily brewed in drinking. The astringent taste of raw gravure leaves is not sufficiently reduced, the texture of raw gravure leaves is not soft, and problems of deterioration may occur due to long-term storage of gravure leaves.

Example 3 Second Drying Step of Graviola

The secondary drying step of the gravureola is a step of drying the dried gravureola leaves in the far infrared dryer. The second drying step of the gravola can be carried out by drying the gravureola leaves at a temperature of 50 to 60 ° C. for 60 to 100 minutes in the far infrared dryer, and drying the gravure leaves using the far infrared dryer to intrinsic to the gravure leaves. It can maintain the fragrance and color appearance and can prevent the change of quality by drying process. When the second drying step of the gravola is performed below the lower limit, the inherent aroma of the gravola may not be sufficiently enhanced in the manufactured gravola tea, and acetogenin (Acetogenins), which is an active ingredient contained in the gravola, may be used. If it is not activated enough may occur, and if it is carried out in excess of the upper limit it is difficult to maintain the color of the gravure inherent to be excessively dry and may cause a problem that the components contained in the raw gravure leaves.

Example 4 Grinding and Grain Removal of Graviola

Grinding and pulverizing the gravureola is a step of removing the powder of pulverized after cutting and grinding the dried gravureola leaves. The grinding and fine powder removing step may be performed using a grinder, etc. The grinding and fine powder removing step may use a method known in the art. The average diameter of the gravureola leaves in the grinding and fine powder removal step is preferably in the range of 01 to 30mm. The average diameter is defined as the average diameter of the gravureola leaf fragments, which is the largest number among the crushed gravureola leaf fragments, and the diameter can be defined as the length of the gravureola leaf fragments based on the largest length dimension. .

The gravure and pulverization step of gravure may be crushed by repeatedly rubbing the gravola leaves. The gravure leaves may be uniformly removed from the surface of the gravola leaves while the gravure leaves are uniformly removed. By properly destroying the tissues of your cell, you can create a gravure-like leaf that's good for internal components. In the grinding and grinding step, the graviola leaves may be ground to have an average diameter in the range of 1 to 30 mm. When the average diameter of the graviola leaves is ground to less than 01 mm, the graviola leaves are ground due to the grinding of the graviola leaves. It may deteriorate, and if it is crushed more than 30mm, it may take a long time to immerse the gravola tea in water.

Example 5: Preparation of Graviola Tea

80 parts by weight of graviola powder is mixed with 20 parts by weight of bellflower powder, and then 60 parts by weight of the mixture is mixed with 10 parts by weight of a Makgeolli silver water mixture containing 75% by weight and 3 ppm by weight of 25% by weight of silver water, and the mixture is aged at room temperature for 48 hours. After the natural drying, and then dried by hot air drying, the pulverized product is prepared in one of a ring, granules and powder.

The sensory evaluation was conducted on taste, aroma, appearance (color), and general preference of the tea produced through the examples. The results of the sensory test were conducted on 50 food-related experts and consumers. As a standard, 9-point scoring was used. Graviola tea prepared according to the embodiment was found to be excellent in taste, aroma, appearance (color) and overall preference compared to the tea produced.

The intrinsic flavor and aroma of the gravure tea produced according to the embodiment lasts longer than that of the conventional green tea, and at the same time, it is judged to satisfy the preference of health-oriented consumers who want a new kind of tea.

It can be seen that the taste, aroma, appearance (color), and general preference of the gravure tea liquid tea prepared according to the embodiment are excellent.

The taste and aroma were not sufficiently balanced and extracted by a high temperature extraction method to leach out unnecessary components of the gravola, thus reducing consumer preference.

Although a preferred embodiment of the present invention has been described, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. Therefore, it should be understood that one embodiment described above is illustrative in all respects and not restrictive.
