Description

Cleaning method of ginger using micro bubble

The present invention relates to a method of washing ginger using a microbubble, and more specifically, removing foreign substances and washing the peeled ginger with electrolytic water or chlorine water firstly; It relates to a method of washing ginger using a microbubble comprising the second washing the ginger washed with the washing water with a microbubble.

Ginger (Ginger), also known as shrimp, Saeyang, is native to Southeast Asia and grown as a vegetable, but is widely used for spices, food, and medicinal use.

Ginger roots grow to the side, fleshy, lumpy, yellow, with a spicy taste and aroma. In each node of the rhizome, fake stems made of leaf stands upright, reaching a height of 30 ~ 50cm, and the leaves are arranged in two rows on the upper part. Leaves are alternate, row-shaped bar-shaped, narrow ends, long leaf bottom.

In Korea, the flowers do not bloom, but in the tropics, the stems of 20-25 cm long, which are wrapped in leaf shops, appear in August, and the flowers grow at the end. Flower comes out between poinsets and 4 ~ 7.6cm long. Calyx is short tubular shape, and the end of corolla is divided into three, and the fragment is pointed at the end. Stamen is one and anther is yellow. The ovary is the lower part and the pistil is thin like a thread.

Ginger roots are dried and used as spices for breads, sweets, curry, sauces, and pickles. Peel, boil, and then marinated in syrup. Ginger tea and ginger are also made. In oriental medicine, dried root stem is used as a medicine, which is effective for indigestion, vomiting and diarrhea, promotes blood circulation, and has anti-inflammatory and analgesic effects.

Ginger is a high-temperature crop, so germination should be at least 18 ℃, grow well at 20-30 ℃, and not below 15 ℃. Breeding is often rooted down.

Ginger has been widely used as an aromatic substance to correct bad smells and tastes, such as fishy smell. In addition, it has been used for the treatment of nausea, and health (健 薑) is used when metabolic function is impaired or when cough, dizziness, cold hands and feet, low back pain, diarrhea, vomiting is used as a treatment.

Ginger is widely used as a dietary and medicinal herb, especially in restaurants where large quantities of ginger are used. Always wash the ginger and then use it for cooking. There is discomfort to be done. In particular, the soil, foreign matter and residual pesticides in the deep bone between ginger is not removed well, so when used as a raw material such as kimchi has a very unsanitary problem. Therefore, the present invention provides a washing method of washing ginger to clean the foreign matter between the deep bone between ginger by first washing with electrolyzed water or chlorine water to first wash with washed water of electrolytic water or chlorine water in order to increase the storage capacity of the washed and peeled ginger. To provide.

The present invention the first washing with a specific washing water for the washing water to wash ginger during the research to solve the above problems and then the second washing with a micro bubble (micro bubble) of the micro-drops ginger when washing ginger The present invention was completed by knowing a method of washing ginger, which has excellent characteristics on the total bacterial count, hardness, weight loss rate, mold occurrence rate, and the like.

Experimental Example 5

In order to process the peeled / washed ginger, the foreign substances such as soil are washed by the first spray type water pressure, and then the first washed ginger is peeled off using the high pressure hydraulic spraying method, and the second peeled ginger is washed with 120ppm of electrolyzed water. After sterilization / washing, finally, purified water was used to remove the dirt and foreign matters deep between the ginger bones once again washed / peeled ginger with a microbubble having a particle size of 10 to 50 μm. In order to increase the freshness of the ginger, the quality of the ginger was investigated in LDPE packaging (0.04mm).

Unwashed soil ginger (control-N:-◇-), unwashed soil ginger packed with LDPE 0.04mm thickness (control-P:-□-), washed for 10 minutes with a regular bubble (normal bubble) -N:-△-), washed 10 minutes with a regular bubble, and then packed in LDPE 0.04mm thickness (normal bubble-P:-ㅧ-), 10 minutes with a microbubble (microbubble-N: -*-), And washed with a microbubble for 10 minutes and then packaged in LDPE 0.04mm thickness (microbubble-P:-○-).

The total microorganism (Log CFU / g) change, weight loss rate, hardness change, and mold incidence rate for the ginger of each test and control were measured, respectively, while keeping at room temperature for 14 days for the ginger of the test and control. The results are shown in FIGS. 5A-5D.

In the results of FIG. 5a, it was found that the first microbial-P and microbubble-N, which were washed with ginger for 10 minutes after the first washing with 120 ppm of electrolyzed water, had the lowest total number of bacteria produced.

In the results of FIG. 5b, it was found that the microbubble-P and the microbubble-N, which were washed with ginger for 10 minutes after the first washing with 120 ppm of electrolyzed water, had the smallest weight loss ratios.
