{The manufacturing method of dried citrus unshiu peel tea using organic citrus unshiu}

The present invention relates to a method of manufacturing dermis tea using organic citrus fruits, and to crush the semi-dried dermis of the tangerine's rind to a certain size or less, and classify it according to its size into a multi-use and tea bag, and apply heat to each flavor The dermis tea is prepared by a roasting process and appropriate packaging, adding the dermis tea to hot water according to the method, and drinking the tea with good taste and aroma.

Generally, the dermis is dried citrus peel, which contains more vitamin C than citrus pulp, which is good for fatigue recovery, cold prevention, skin care, and helps calcium absorb into the body. Vitamin P is a fruit-only ingredient in citrus fruits, which enhances the action of vitamin C and protects capillaries, preventing high blood pressure and arteriosclerosis, and the dermis when eating, vomiting, or diarrhea. It is also used as a remedy even when the stomach is simmered and topped, which is eaten as a tea as a decoction, mixed with other medicines, decocted, or used as a bath because of its fragrance, which refreshes the body and keeps the body warm.

However, despite the above effects, citrus cultivated by the conventional method is applied to the pesticides to prevent pests, to coat the film to maintain freshness, and to apply wax to make it look better, rather than using the peel of citrus to make the dermis In addition, care should be taken to clean the tangerines before they are separated into skins, and to dry the skins from which the flesh is separated, to avoid decay.When drinking this dermis with tea, since the dermis is dry, it must be cut off for a long time to drink tea. Not only is not simple, and there is a problem that vitamin C is destroyed for a long time, and if the dose of the dermis is not properly adjusted, it is too soft, or the fragrance is difficult to drink.

Therefore, the present invention, in order to solve the above problems, crush the semi-dried dermis of organic tangerine peel to a certain size or less, and classify it according to the size for multi-tolerance and tea bags, by applying heat to the classified dermis particles The dermis tea can be manufactured through a roasting process that adds flavor and proper packaging, and it can be easily consumed with a high taste and aroma because it is soaked in high temperature water to minimize the breakdown of vitamin C and to recover from fatigue and cold. The purpose of the present invention is to provide a dermis tea that is good for prevention and skin beauty and easy to store.

The present invention relates to a method of manufacturing dermis tea using organic citrus fruits, and to crush the semi-dried dermis of the tangerine's rind to a certain size or less, and classify it according to its size into a multi-use and tea bag, and apply heat to each flavor The dermis tea is prepared by a roasting process and appropriate packaging, adding the dermis tea to hot water according to the method, and drinking the tea with good taste and aroma.

Referring to the manufacturing method of the present invention with reference to the process diagram of Figure 1, first, first, the organically grown citrus, and washing and drying the tangerine to remove water by washing it clean (S1), pulp in the peel of the tangerine Citrus pulp and skin separation process (S2), which separates the parts and collects the skin, skin drying process (S3), semi-drying the separated skin, and dermis grinding process (S4), which pulverizes the dried dermis to 0.8 mm or less. , Dermis particle sorting process (S5) for separating the pulverized dermis into multi-tubes and tea bags according to its size, dermal particle roasting process (S6) for thermally processing the sorted dermis particles, respectively, and finally, the dermis having been roasted Dermal tea is completed by the manufacturing method of the dermis tea packaging factory (S7) that the particles are properly packaged according to the method of eating dermis tea, such as for tea and tea bags.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for manufacturing dermis tea according to the present invention will be described in order according to the process diagram of FIG. 1. First, the washing and drying process (S1) of citrus fruits is performed by thoroughly washing selected organic citrus fruits to completely remove dust attached to the skin. To clean, or blow and blow dry, the fruit tangerine and peeling process (S2) of separating the flesh from the clean dried citrus and collect the peel, that is, citrus peel, by hand or by machine This is possible.

Next, the skin drying step (S3), the dried skin is naturally dried in the sunlight, it is preferable to semi-dry rather than completely dried, the reason for drying the skin in the sunlight is more delicious than the shade This is because the fragrance is better, and the reason for semi-drying is to obtain particles of the appropriate size in the grinding process to be sedimented, and to reduce the loss rate that is easily burned away when heated in the roasting process. Citrus peels get dry dermis.

In addition, the dermis grinding step (S4) is a step of grinding the dried skin, that is, the dermis to 0.8 mm or less, when the dermal particles are larger than 0.8 mm, the taste and aroma are soft, the texture is poor, to improve palatability It is not economical because a large amount is consumed, and the following dermal particle sorting process (S5) separates and selects the pulverized dermal particles according to their thickness, for multi-use and tea bags, and the multi-use for removing dermis particles 0.5 Selected to a thickness of 0.8 mm to prevent tea from using a multi-tube, so as not to escape from the strainer, for tea bags to increase the palatability of the dermis by using the dermis particles in a thickness of 0.3 mm or less.

This dermal particle roasting process (S6) is to heat the selected dermal particles to increase the fragrance and palatability, which is that when the heat is temporarily heated with a high temperature heat, the surface of the dermal particles burns before the inside of the dermal particles are roasted As the loss rate of falling and discarding is increased, when the halogen heat heater is used as the heat source of roasting, the inside and the outside of the dermis particles are roasted evenly to increase the taste and aroma, and the far infrared rays are radiated to improve the quality. Dermis tea packaging process (S7), the dermis, the dermal tea is packaged, but the dermis particles having a size of 0.3 mm or less packed in a tea bag with a weight of 1 to 1.3g provided for a tea bag, or packed according to the unit amount Packaged for multi-pipes to complete dermal tea production.

As described above, tea and tea bag-type dermis teas using organic citrus fruits have a high temperature, preferably 80 ° C., about 1 g, and then drink honey or sugar-derived tea. It is easy to drink dermis tea with excellent fragrance and does not have to be long or hung, so it minimizes the destruction of vitamin C, is good for fatigue and cold prevention, and uses organic tangerines that do not contain ingredients such as pesticides and waxes. There is a characteristic that chemical substances harmful to human body do not accumulate in the body and are easy to store.

On the other hand, ingredients and palatability using dermis of Jeju citrus unshiu were tested. First, in the experimental materials and methods, the pretreatment method of the sample, the extract of the rind, the pulp solvent, and the calculation of the amount of water, total The phenol content measurement method, DPPH free radical scavenging ability measurement method, cell toxicity measurement method, physicochemical test method of dermis tea, sensory test method of dermis tea will be described as follows.

First, in the pretreatment of the sample, the mandarin is selectively washed, the peel is separated from the mandarin, and the peel is pulverized to -70 ° C. to less than 2 mm, stored at 4 ° C., and used for leaching the dermis. 1g each of the dermis dry powder is used for the experiment.

Second, the dermis, pulp solvent extraction and yield calculation, the dermal dry powder is extracted with different polarities in the order of nucleic acid, chloroform, ethanol, respectively, which is 5ml of the nucleic acid in 5g of the dermis, incubated for 30 minutes at 4 ℃ After shaking in a water bath (Bio Shaker, BR-30LF, TAITEC, Japan), the nucleic acid solution was recovered, and 5 ml of chloroform was added to the remaining residue, followed by extraction in the same manner. ㎖ was added sequentially, and each solution was concentrated under reduced pressure with a concentrator (Buchi, 461, Germany), dried and weighed. THF (THF, tetrahydrofuran) was added to 3 ml of the solution and stored at -20 ° C.

Third, the total phenol content measurement method is a variation of the Folin ciocalteu method, which is a tea prepared by dissolving diluted 1 ml samples or standards (chlorogenic acid: Sigma Chemical Co., St. Louis, MO, USA). 9 ml of distilled water was added to 1 ml of HF solution, followed by stirring. After 3 minutes, 1 ml of Folin ciocalteu phenol reagent (Sigma Chemical Co., St. Louis, Mo., USA) was added thereto, followed by stirring. 10 ml of 7% Na ₂ CO ₃ solution was added thereto, stirred, diluted with 25 ml of distilled water, and allowed to stand at 23 ° C. for 90 minutes, using a spectrophotometer (DU 530 spectrophotometer, Beckman, 4300N, Fullerton, USA). Absorbance was measured at 750 nm. The total phenol content was calculated by preparing a standard calibration curve with chlorogenic acid (Sigma Chemical Co., St. Louis, MO, USA) and expressed as mg gallic acid (GAE) for 100 g wet weight.

Fourth, the DPPH (1,1-Diphenyl-2-picrylhydrazy) free group scavenging ability measurement method, In 0.2 ml of dilution solution of the dermal solvent extract according to the method of Chu et al., 4 × 10 ^-4 M 1,1-Diphenyl-2-picrylhydrazy (DPPH: Sigma Chemical Co., St. Louis, MO, USA) solution 0.8 ml was added, mixed for 10 seconds, and left at room temperature for 10 minutes, and then absorbance was measured at 517 nm. The control group was added 0.2 ml of THF to 0.8 ml of DPH solution, and then added at room temperature for 10 seconds. After leaving for one minute, absorbance was measured at 517 nm. The formula is as follows.

DPPH radical scavenging activity (%)

  = (1-sample absorbance / control absorbance) × 100

Fifth, let's talk about measuring cytotoxicity. Prostate cancer cells of PC-3 and LN-CaP were distributed by the Korea Cell Line Bank (KCLB) and 10% fetal bovine serum (FBS: Sigma Chemical Co., St. Louis, MO, USA), 1% penicillin and streptomycin (Sigma). Chemical Co., St. Louis, MO, USA) was cultured using RPMI-1640 (GIBCO ^™ , Invitrogen, CA, USA), and the cytotoxicity of the dermal extract was determined according to Nagao et al. 4, 5-dimethylthiazol-2 -yl) -2, 5-diphenyl tetrazolium bromide (MTT: Sigma Chemical Co., St. Louis, MO, USA) using a reagent, at a concentration of 5 × 10 ⁴ cell / well After dispensing in a 96 well plate, incubating for 72 hours at 37 ° C., 5% CO ₂ incubator, removing the medium used for the culture, and adding 180 μl of fresh medium and 20 L of dermis extract, the concentration of the added dermis extract Are added at 0, 2.5, 12.5, 25.0 μg / mL, and cultured again for 24 hours, and then the medium was removed, and 200 μL of well (MTT) reagent at a concentration of 0.5 mg / mL was used. After 4 hours, absorbance was measured at 595 nm using an ELISA microplate reader (Bio-rad, Benchmark, USA).

Sixth, in the physicochemical examination of dermis tea, pH measurement was performed by immersing 1, 2 g of dried dermis powder in 80 ml of water at 60 ° C, 80 ° C, and 100 ° C for 3 minutes, and then taking 5 ml of leachate and taking a pH meter (710A). , Orion, USA), the measurement of soluble solids was measured with a hand-held refractometer (Atago, Japan) and expressed in ° Brix, and the color difference was measured by a colorimeter with a liquid accessory (Colorimeter, CM S7W, Minolta, Japan). ) Was used to measure the chromaticity of the sample, but the color space was measured by adjusting the hunter color system L (brightness), a (redness), and b (yellowness).

Seventh, the dermal tea sensory test method is to examine the sensory differences between dermis tea and sensory evaluation education and training for 20 graduate students of the Department of Food and Nutrition, Seoul National University. The degree of preference was evaluated, and all the characteristics used the 7-point scale, so that the higher the number, the higher the characteristics of the item, that is, 7 points are 'very strong', or 4 points are 'very good', and 1 point is 'normal' `` Very weak, '' or `` Very bad. ''

Finally, the statistical process is described using ANOVA analysis of variance and Duncan's multiple range test using the SAS / STAT ™ User's Guide 8.0 edition program. Probability values are p Interpretation was at the level of <0.05.

Next, the experimental results through the above treatment method, that is, the general components of dermis, characteristics of dermis tea at different leaching temperatures, total phenol content and free radical scavenging ability, killing effect of dermal solvent extracts on cancer cells, sensory test of dermis leaching tea Looking at the results with reference to Tables 1 to 7, but first, looking at the general components of the dermis with reference to Table 1 and Table 2, first, as shown in Table 1 crude carbohydrate per 100g of edible (61.6 ± 0.3 mg) , Crude fat (15.0 ± 20 mg), crude protein (8.3 ± 2.1 mg), crude ash (7.6 ± 0.1 mg), and moisture (7.5 ± 0.2 mg) in that order. As in, the mineral content per 100g of dermis was potassium 3029 ± 110 mg, calcium 705 ± 20 mg, magnesium 495 ± 10 mg in the order of potassium, calcium, magnesium, phosphorus, sodium, iron, zinc.

Physicochemical composition contents of the Citrus unshiu peel (per 100g edible portion) Moistures (g) Crude protein (%) Crude fat (%) Crude carbohydrate (g) Crude ash (g) 7.5 ± 0.2 8.3 ± 0.1 15.0 ± 0.5 61.6 ± 0.1 7.6 ± 0.1

¹⁾ All mean values are triplicate determinations. Mean ± standard deviation.

Second, look at the characteristics of the dermis tea by leaching temperature with reference to Table 3, which measured the amount of pH, chromaticity, soluble solids by leaching temperature in order to determine the dermis leaching tea processing characteristics, which is the pH of dermis 1g tea The pH of the dermis tea decreased as the leaching temperature was increased to 6.0 at 6.5 and 100 ° C at the leaching temperature of 60 ° C. Also, the pH of the dried dermal tea 2g was 6.3, 6.2, and 5.9 for each temperature of 1g of the dermis. The pH tends to change with temperature, but 2g of dermis shows a lower pH value than 1g, and the factor affecting pH during tea leaching is the organic acid contained in tea, and the type of organic acid detected in Jeju citrus juice Were oxalic acid, citric acid and malic acid, and citric acid was detected in pulp (Song EY et al, 1998).

In addition, in this study, the higher the dermis content and the higher the leaching temperature, the higher the leaching of the organic acid, which is thought to decrease the pH.The amount of solids by temperature of the dermis leaching tea was 60, 80, All were 0.9 ˚Brix at 100 ℃ and 0.9g, 0.9, 1.0 ˚Brix at 60, 80 and 100 ℃ for 2g of dermis, respectively, and the leaching solids increased with increasing leaching temperature, but there was no statistical significance. The color difference of the leaching tea according to the leaching temperature decreased with increasing temperature, and the L value of the tea of 1g of dermis was 95.6 at 60 ℃ but 92.6 at 100 ℃.

In addition, the redness of the dermis 1g was 1.0 at 60 ° C, but 2.8 at 100 ° C and 24.8 at 60 ° C, and 31.5 at 100 ° C, respectively. The 2g dermis tea also showed a similar color difference to the 1g tea dermis, and as the amount of leaching powder increased, the redness and yellowness tended to increase. Therefore, as the leaching temperature increased, the brightness of the leaching tea became brighter and the redness and yellowness increased. The degree was increased to show that the yellow became stronger overall.

Fourth, explaining the apoptosis effect of the dermal solvent extract on cancer cells, first, to examine the prostatic cancer cell inhibitory effect of the three solvent extracts of the dermis, PC-3, LN-CaP cell death experiments on prostate cancer cells The results are shown in Tables 5 and 6, and the PC-3 and LN-CaP cells used in this experiment are all dependent on androgen, and this androgen hormone is a hormone representing male masculinity. Excessive secretion is characterized by the growth of prostate cancer cells (Jane M. 1998). Therefore, it was found that the treatment of the extracts on the two cells effectively inhibited the hormone-dependent process by examining the cytotoxicity. The ethanol solvent extract of the dermal solvent extracts showed a good inhibitory effect on both cancer cells, that is, the dermis. Both ethanol extracts showed a high inhibitory rate of about 60% in PC-3 and LN-CaP cells compared to the control group, and the dermal solvent extracts inhibited prostate cancer on the cells.

Finally, the sensory test of the dermis leaching tea is described, but referring to Table 7 showing the sensory test results of the leaching tea with different temperature levels, the sensory test items include dermal odor, color, sourness, bitter taste, The overall acceptability was evaluated, and there was a significant difference in dermal odor, color and overall acceptability.The dermal odor of dermis 1g was 4.30 at 60 ℃, 4.92 at 80 ℃, 5.99 at 100 ℃, and leached at 100 ℃. The dermal odor of tea was evaluated to be the strongest (p <0.05). This is the same result for 2g of dermis. As the temperature is higher, the dermal odor becomes stronger.

As shown in the color difference results of Table 3, the higher the leaching temperature, the higher the b-value (yellowness) of the dermis difference was observed. The color of the dermis tea was evaluated as yellow, and as the leaching temperature increased, the sour and bitter taste of the dermis tea were gradually evaluated, but there was no significant difference.The overall acceptability was 3.84 at 60 ℃ and 5.42 at 80 ℃ for 1g of dermis. In the case of 2g of dermis, the overall acceptability of the dermis tea, which leached 1g of dermis at 80 ° C, was evaluated to be 4.11 at 100 ° C.

Therefore, this is considered to be lower than the preference of the dermis tea leached at 80 ℃ because the various flavors and astringent components of the dermis are leached at the high temperature such as 100 ℃ to drink the drink Since the unique components of the dermis are not sufficiently leached at the temperature, and thus the palatability seems to be low, it is considered that leaching the dermis tea by leaching the amount of 1 g of the dermis at 80 ° C. is considered a preferable method to increase the palatability of the dermis tea.
