1 is a bamboo shoot storage method according to an embodiment of the present invention.
The present invention comprises a step of immersing bamboo shoots in an immersion liquid containing 0.1 to 5% by weight of an organic acid, and a step of vacuum-packing and heat-sterilizing the bamboo shoots soaked, To a storage method of bamboo shoot having an excellent taste, an excellent hygiene property, a low-salt diet, and a low-cost distribution.
Hereinafter, the present invention will be described in more detail.
The method for storing bamboo shoots according to the present invention comprises: immersing bamboo shoots in an immersion liquid containing 0.1 to 5% by weight of an organic acid; And vacuum packaging and heat sterilizing the bamboo shoot which has been subjected to the immersion treatment.
The bamboo shoots are immersed in an immersion liquid containing 0.1 to 5% by weight of an organic acid.
Bamboo shoots are young and light buds that bloom in bamboo shoots. Among the bamboo shoots, bamboo shoots are usually used for edible purposes such as royal crowns, pods, and bamboo shoots. It is known to contain calcium, phosphorus, iron, and salt in addition to proteins, sugars, lipids, fibers and ash.
Organic acid is a generic term for organic compounds with acidity. Organic compounds containing carboxyl groups or sulfone groups are representative organic acids.
The organic acid is, for example, acetic acid or citric acid. Acetic acid and citric acid can be used in various ways such as vegetables and fruit products which can be easily used in farm households and can be stored at low cost because they are low in cost.
The immersion liquid includes purified water and organic acid, and may further include sugar, salt and calcium chloride as necessary.
The organic acid in the immersion liquid is contained in an amount of 0.1 to 5% by weight. The content of the organic acid may vary within the above range depending on the type of the organic acid, the immersion time, the amount of the bamboo shoot, etc., and is preferably from 0.3 to 2% by weight and more preferably from 0.5 to 1.5% by weight under ordinary conditions.
The immersion time is preferably from 1 minute to 30 minutes. It may vary depending on the kind and content of the organic acid.
For example, when citric acid or acetic acid is used as an organic acid when immersing in an immersion liquid capable of completely immersing 2 kg of bamboo shoots, 2 kg of bamboo shoots are added to the immersion liquid containing citric acid or acetic acid at 0.5 to 1.5 wt% for 5 to 15 minutes It is preferable to immerse the film.
If the pH of the bamboo shoot is lowered to 4.5 or less by immersing the bamboo shoot in the immersion liquid containing 0.1 to 5 wt% of the organic acid in the present invention, the growth of microorganisms can be suppressed and the distribution period can be prolonged. If the content of the organic acid exceeds 5 wt%, the texture of the bamboo shoot raw material is softened, and the strong acid strong flavor is strong, so that there is a problem that the sensory preference is lowered.
In the present invention, the soaked bamboo shoot treated by immersion is heat-sterilized after vacuum packaging.
Vacuum packaging means wrapping bamboo shoots on a flexible film and degassing the inside of the film while sealing the periphery of the film by welding.
Plastic films for foods are mainly used as packaging materials, for example, nylon, polyethylene and the like can be used.
Bamboo shoots are heat sterilized after vacuum packaging. The heat sterilization method can be applied without limitation to those widely used in the field of food. For example, the bamboo shoots packed in boiling water (at a temperature of 100 ° C at normal pressure) may be immersed for 1 to 10 minutes to sterilize by heating.
The heat sterilization time may be from 1 to 10 minutes, from 2 to 8 minutes, or from 3 to 6 minutes. The heat sterilization time may vary depending on the content of organic acid in the previous step, the amount of bamboo shoots, the immersion time, and the like. According to one embodiment, the bamboo shoots immersed in an immersion liquid containing 1 wt% of citric acid are preferably heat-sterilized in boiling water for 4 to 6 minutes, and the bamboo shoots immersed in an immersion liquid containing 1 wt% It is preferable to heat sterilize in boiling water for 3 to 6 minutes.
If the heat sterilization time is less than 1 minute, the microorganisms may not be sufficiently killed, resulting in corruption of bamboo shoots during storage for a long period of time. If the heat sterilization time exceeds 10 minutes, .
The storage method of the present invention may further include the following steps as needed.
First, the bamboo shoots can be treated with steam (at 100 캜 water vapor at normal pressure) before being immersed in the immersion liquid containing the organic acid. Steam treatment is effective in removing the epidermis of bamboo shoots. According to one embodiment, the bamboo shoots can be heated with steam at about 100 캜 for 30 to 60 minutes. If excessive steam treatment is applied, the texture of bamboo shoots may be deteriorated.
Next, after the steam treatment, the bamboo shoots can be immersed in running water for 5 to 20 hours, preferably 8 to 12 hours to remove the arginine taste.
Finally, it may include a variety of additional processes commonly used in food packaging processes.
Hereinafter, the present invention will be described in more detail by way of examples. It is to be understood that these embodiments are only for describing the present invention in more detail, and the scope of the present invention is not limited to those exemplified in these embodiments.

In the above Tables 1 and 2, pH was decreased with increasing citrate and acetic acid concentration and immersion time. In Table 1, the pH of the bamboo shoots immersed in the immersion liquid containing 0.5 and 1 wt% of acetic acid for 5 minutes, 10 minutes, and 15 minutes was decreased to 4.5 or less. In Table 2, the pH of bamboo shoots immersed in the immersion liquid containing citric acid at 0.5 wt% for 10 minutes and 15 minutes was decreased to 4.5 or less, and the immersion solution containing citric acid at 1 and 1.5 wt% , 10 min and 15 min, respectively. Therefore, it can be seen that a pH suitable for long-term storage and distribution at room temperature of bamboo shoots can be obtained at the time of treatment as described above.
<1-2> Microbiological characterization of hot-bacterium bamboo shoots
Acetic acid and citric acid at a concentration of 1% by weight was immersed in bamboo shoots for 10 minutes, packed in polypropylene, sterilized in boiling water for 1, 2, 3, 4, 5 and 6 minutes, The number of molds was measured and the results are summarized in Table 3.
Total bacterial counts, yeast and molds were determined by standard plate culture method (Jwa, 2002). Samples were homogenized for 3 minutes using a Stock marker (Serial No. 8X0125, Sibata scientific technology LTD, Japan). The mixed sample was diluted with 10 1 -10 7. Total bacterial counts were cultured at 35 ± 1 ° C for 24-48 hours using Plate Count Aagar (Difco, Detroit, USA). Yeast and mold were cultured for 72 hours using 3M Petrifilm ™ Yeast and Mold Count Plate (3M Co., Saint Paul, Minn., USA), and colonies were counted by choosing 30-300 colonies.
All experiments were repeated three times and the mean and standard deviation were obtained. The statistical analysis of the experimental data was performed by Duncan's multiple range test using a SPSS program (version SPSS 19.0) based on Kim (2011) p <0,05).
1% CA: Bamboo shoots immersed in 1% citric acid for 10 minutes
ND: Not detected
Unit: CFU / g
In the case of bamboo shoot (AA 1%) treated with the immersion liquid containing 1% by weight of acetic acid, the total number of bacteria, yeast and molds were detected at 1 and 2 minutes of sterilization, but after 3 minutes of sterilization, total bacteria, yeast and mold And the number was not detected. On the other hand, in the bamboo shoot (CA 1%) treated with the immersion liquid containing 1 wt% of citric acid, the total number of bacteria, yeast and mold number were detected at sterilization times 1, 2 and 3, And yeast and mold were not detected. Therefore, in this study, it seems that the microbiological safety is high when sterilized in boiling water for 3 minutes and 4 minutes after 10 minutes treatment with immersion liquid containing 1% by weight of acetic acid and citric acid, and it can be stored and distributed at room temperature It is expected to be.
<1-3> Sensory characteristics of bamboo shoots after immersion in organic acid at high temperature
The sensory evaluation was carried out by 50 students of Chonnam National University Food Science and Technology, color, aroma, flavor, texture, overall acceptability. In the sensory evaluation, acid treatment and bamboo shoots were immersed in water for 3 hours to remove acids and salts. The results were statistically analyzed with SPSS 19.0 and the significance of the samples was verified by Duncan's multiple range test using ANOVA (significance level p <0,05). Table 4 summarizes the results of analyzing the sensory characteristics of bamboo shoots when the bamboo shoots were immersed in an immersion liquid containing 1% by weight of organic acid for 10 minutes and then heat-sterilized.

1% AA: immersed in 1% acetic acid for 10 minutes, then heated in boiling water at 100 ° C for 4 minutes,
1% CA: 1% citric acid for 10 minutes and then boiled in boiling water at 100 ° C for 5 minutes.
Values represent the mean ± SD
The suffix ad in the upper right corner of the data indicates statistically significant difference in each column (p <0.05).
In all items except color, the control group showed the highest preference level, and there was no significant difference in preference of color. Incense was lowest at 3.96 and 3.98 points after heat treatment, followed by heat sterilized bamboo shoots and frozen bamboo shoots. The taste showed the lowest preference at 2.92 points for frozen bamboo shoots. The heat - sterilized bamboo shoots and salted bamboo shoots after acetic acid and citric acid treatment showed no significant difference. The texture of frozen bamboo shoots was the lowest at 2.90 points. The overall preference was 4.34 points and 4.32 points for heat-sterilized bamboo shoots and salted bamboo shoots after citric acid treatment, respectively, and showed higher preference than heat-sterilized bamboo shoots and frozen bamboo shoots after acetic acid treatment.
On the other hand, it was confirmed that the sour taste of the organic acid affects the bamboo shoot in the organic acid treatment, and the 1% solution of each organic acid had a sensory level of sour taste, but the bamboo shoot was immersed in each organic acid solution for 10 minutes After 3 hours immersion in water, the treated organic acids did not affect the taste of bamboo shoots. Therefore, the sensory characteristics were better than the heat - sterilized bamboo shoots and bamboo shoots after citric acid treatment, and the salty bamboo shoots showed no significant difference in all items except for the texture. Therefore, It is considered to be desirable as a method of possible storage distribution.
<1-4> Long-term storage stability of bamboo shoot after high temperature sterilization after immersion in organic acid
In order to test the long-term storage stability of the bamboo shoots after being dipped in organic acids, the bamboo shoots immersed in an immersion liquid containing 1 wt% of organic acid for 10 minutes and then heat sterilized at 45, 35, After storage for 150 days and 300 days, microorganisms were detected. The experimental results are summarized in Tables 5 to 7.
