The present invention relates to a method of improving the shelf life of quail eggs by spraying or immersing the quail eggs in electrolytic alkaline water, which has a strong bactericidal power against fruit vegetable rot microorganisms, and which is stable to the living body and is non-polluting. The present invention also relates to a method of further improving the shelf life of quail eggs by further treating the wax or mineral oil stock solution, which is a coating agent after spraying or dipping electrolytic alkaline water into quail eggs.

Quail eggs are not only delicious but also highly nutritious and are processed and marketed in a variety of ways. However, because of the short shelf life and storage at room temperature, freshness is a problem. In addition, quail eggs, like eggs, are highly contaminated with Salmonella sp., A fatal food poisoning bacterium in humans. Because egg shells are very thin compared to eggs, they tend to crack easily during handling, and are more likely to be contaminated. Salmonella bacteria penetrate inside and multiply inside the egg shell when the humidity is moderate.

On the other hand, the electrolytic alkaline water is a functional water having the advantages of safety and pollution-free to the living body while having a very excellent disinfection and disinfection effect at the same time. It is produced by electrolysis of water. In other words, electrolysis of water using an electrolyzer produces two kinds of water, each with different properties, in the anode and cathode.The water produced at the anode is strongly oxidized water, and the electrons are extremely deficient. Extremely rich strong reduced water, ie electrolytic alkaline water. Electrolytic alkaline water is prepared by adding a small amount of NaCl to water, and strong redox water with a redox potential difference of about -200 mV. The small size of the water molecule population makes it easy to penetrate into the cell and has fast metabolism. When salt or chlorine is present in the water, several stages of reactions occur in the electrolysis process to produce safe and bactericidal active chlorine (HOCl), which is dissolved in the anode water. And since HOCl is a heavy component, it can penetrate into microbial cell membranes more easily than OCl, so it is relatively sterilizing. Electrolyzed alkaline water containing very high concentrations of active oxygen (O, O ₃ , H ₂ O _2, etc.) and large amounts of dissolved oxygen (O ₂ ) contains minerals (Cu, Mn, Zn, Co, Mo, etc.) that are essential for life. It contains trace amounts to activate living organisms, and studies are being conducted in advanced foreign countries to prevent diseases of positive and negative electrolyzed water, to promote growth, to promote germination of seeds, to sterilize cultured water, and to control pollution-free ions in hydroponic cultivation. In addition, due to the wide range of treatments and the advantages of having few harmful residues unlike general chemicals, a lot of researches have recently been made for use in food processing and storage.

Meanwhile, various coating products, such as wax, chitosan, and soy protein, are being researched and developed in order to extend the shelf life of food and maintain freshness. Quail eggs are thin in shell and are mainly stored and distributed at room temperature, so the shelf life is short and there is a great possibility of corruption and food poisoning due to internal pollution.

Therefore, the present invention examines the effect of extending the shelf life of quail eggs when treating electrolytic alkaline water, which is harmless to the human body and has strong sterilizing power, or when treating wax and mineral oil, respectively, with the coating electrolytic water simultaneously with alkaline electrolytic water. We want to provide the most effective way to improve.

Therefore, the objective of this invention is providing the method of improving the shelf life of quail eggs by electrolytic alkali water treatment alone or a combination treatment with a coating agent.

The technical problem of the present invention relates to weight loss rate and egg yolk coefficient which can be sprayed or immersed in electrolytic alkali water to quail eggs alone, or used in combination with a coating agent, and can serve as an index indicating the storage capacity of quail eggs for each sample. Experiments were accomplished by deriving the method that was most effective in improving the shelf life of quail eggs.

The present invention relates to a method of improving the shelf life of quail eggs by spraying or immersing the quail eggs in electrolytic alkaline water, which has a strong bactericidal power against fruit vegetable rot microorganisms, and which is stable to the living body and is non-polluting. The present invention also relates to a method of further improving the shelf life of quail eggs by further treating the wax or mineral oil stock solution, which is a coating agent, after spraying or dipping electrolytic alkaline water on the quail eggs.

According to the present invention, when electrolytic alkaline water having a pH of 12 ± 0.2 and a redox potential of -200 ± 100 mV is sprayed or immersed in the range of the stock solution to 1/100 dilution, the weight loss rate is low and the yolk coefficient value is in quail eggs. Since it is high, there is an effect which remarkably improves the shelf life of quail eggs.

The present invention comprises the steps of measuring the change in weight and yolk coefficient of the quail eggs while spraying and storing the quasi-alkali dilute or diluent electrolytic solution; Measuring the weight and egg yolk coefficient change of the quail eggs while immersing and storing the quail eggs in the electrolytic alkaline water stock solution or diluent; And immersing and drying the quail eggs in the electrolytic alkaline water stock solution or dilution solution and measuring the weight and yolk coefficient change of the quail eggs while storing and treating the wax or mineral oil stock solution as a coating agent.

Hereinafter, the specific method of the present invention will be described in detail with reference to Examples, but the scope of the present invention is not limited only to these Examples.

Example 1 Storage Method of Quail Eggs after Electrolytic Alkaline Water Treatment

Quail eggs, a test sample used in the experiment, were purchased directly from Hayang Market in Gyeongsan, Gyeongbuk, in August 2003. Waxes and mineral oils used as coating agents were purchased from Jeju Clean Farming Association (trade name: KF-8000, domestic) and Sigma Aldrich Korea (Sigma Co. Ltd., USA).

Electrolytic alkaline water was prepared by electrolytic reduction water generator, and was provided free from the West. Physical and chemical properties of the electrolytic alkaline water are shown in Table 1 below. It consists mostly of water and contains a small amount of Na by using NaCl as an electrolyte. No harmful chemicals were detected and strong alkalinity of pH 12 ± 0.2. The redox potential was -200 ± 100 mV, which was much lower than that around 600 mV, which is the typical redox potential of distilled water.

Physicochemical Properties of Electrolytic Alkaline Water Measure characteristic Chemical composition H ₂ O: 99.85% Na: 0.14% Si: 0.01% No toxic chemicals detected in humans pH 12.0 ± 0.2 Dissolved oxygen 4 ppm Redox potential -200 ± 100 mV

First, when electrolytic alkaline water and coating agent are treated simultaneously, quail eggs are immersed in diluent diluted 1/5, 1/10, 1/100 with electrolyzed alkaline water or distilled water for 5 minutes, taken out, dried, and then coated with wax, which is a coating agent. Each of the mineral oil stocks was treated and stored at 37 ° C. for 7 days. On the other hand, when only electrolytic alkaline water is treated, immerse in 1/10, 1/100, 1/1000 dilution with electrolyzed alkaline water or distilled water for 5 minutes, or spray it so that the surface is sufficiently wet, and then dry it. Store at 37 ° C. for 7 days.

Example 2 Determination of the Weight Loss Ratio of Stored Quail Eggs

After the treatment by the method of Example 1, the weight change of quail eggs in storage was measured at regular intervals. The degree of reduction relative to the initial weight was measured in the following equation.

Weight loss rate (%) = (Wi-Wt) / Wi x 100

Wi is the initial weight of storage, Wt is the weight after storage for a certain period of time, and the number of quail eggs used for weighing is 24 pieces for each treatment.

As a result, it can be seen that the combination treatment of electrolytic alkaline water and wax diluted to various concentrations has an excellent storage extension effect because the weight loss rate is lower in all treatments than in the treatment-free treatments. In this case, the wax coating after the electrolytic alkali stock solution and 1/10 dilution solution showed about 2 times better effect than the untreated group (see FIG. 1). In addition, when electrolytic alkaline water and mineral oil were used in combination, the shelf life extension effect was high in all treatments when electrolytic alkaline water and mineral oil were used in combination. In addition, all treatments showed a much better effect than using wax as a coating. In particular, when the electrolytic alkaline water solution and mineral oil were used in combination, the weight loss hardly occurred, and it showed that the quality maintenance effect was as much as 30 times that of the non-treated group by maintaining the level similar to the initial state (see FIG. 2). .

In the case of immersion treatment in the electrolytic alkaline water treatment, the value was generally lower than that in the non-treatment, and the difference was larger as the storage period increased. Among them, the undiluted solution and 1/100 dilution recorded about 2 times lower weight loss than the untreated group, which indicates that the electrolytic alkaline water treated group had about 2 times better storage (see FIG. 3). In the case of spray treatment of the electrolytic alkaline water treatment, the value was generally lower than that of the non-treatment, and the difference was larger as the storage period increased. Among them, the undiluted solution and 1/100 dilution recorded about 2 times lower weight loss rate than the untreated group (see FIG. 4). It can be seen that the above results are almost the same as the immersion treatment.

In summary, when the electrolytic alkaline water solution to 1/100 diluent is sprayed or immersed in quail eggs for storage, there is an excellent effect in extending the shelf life of the quail eggs, and in the case of additional coating treatment after the spraying or dipping treatment It can be seen that there is an excellent effect of further improving the shelf life of quail eggs.

Example 3: Measurement of yolk index of stored quail eggs

The yolk index (Y. I.) of the quail eggs stored after treatment by the method of Example 1 was measured at regular intervals. After the eggshells of the quail eggs were carefully crushed to prevent the egg yolk from being destroyed, the yolk and egg white were transferred to a Petri dish. The yolk coefficient was obtained by dividing the height of the yolk by the diameter of the yolk, and the average value was obtained by measuring the diameter and height of at least five yolks for each treatment. The diameter and height were measured using Vernier Calipers (Mitutoyo Co. Ltd., Japan).

After dipping the quail eggs in the electrolytic alkaline water stock solution and diluent, the results of measuring the yolk coefficient are shown in Table 2 and FIG. 5. The electrolytic alkaline water treatment group showed a higher value than the non-treated group, and the highest values were obtained in the electrolytic alkaline water solution and 1/100 diluent. In particular, as shown in the results of FIG. 5, after 7 days, the untreated ball was completely destroyed because the yolk was destroyed, but in the electrolytic alkaline water treatment, the condition of the yolk was generally good.

Egg yolk coefficient during electrolytic alkaline water immersion treatment Storage period Control Electrolytic Alkaline Water Solution 1/10 dilution 1/100 dilution 1/1000 diluent 0 days 0.25 0.25 0.25 0.25 0.25 1 day 0.16 0.24 0.24 0.24 0.24 3 days 0.12 0.16 0.16 0.17 0.13 5 days 0.10 0.12 0.09 0.14 0.10 7 days 0 0.10 0.08 0.13 0.04

On the other hand, when comparing the results of Table 2 and the results of Figure 3 it can be seen that they are increasing or decreasing inversely. That is, the electrolytic alkaline water treatment group showed lower weight loss rate and higher yolk index value than the non-treated treatment group. Therefore, the lower the weight loss rate and the higher the yolk coefficient value of the storage quail eggs, the better their storage properties.

The result of measuring the yolk coefficient after spraying the electrolytic alkaline water stock solution and dilution solution on quail eggs is shown in Table 3 below. The electrolytic alkaline water treatment group showed a higher value than the non-treated group, and the highest values were obtained in the electrolytic alkaline water solution and 1/100 diluent. It can be seen that this result is also similar to the case of immersion treatment of alkaline water.

Egg yolk coefficient during electrolytic alkaline water spray treatment Storage period Control Stock solution 1/10 dilution 1/100 dilution 1/1000 diluent 0 days 0.25 0.25 0.25 0.25 0.25 1 day 0.16 0.24 0.25 0.25 0.25 3 days 0.12 0.16 0.16 0.17 0.17 5 days 0.10 0.12 0.12 0.13 0.11 7 days 0 0.10 0.09 0.11 0.03

From the above results, it can be seen that the electrolytic alkaline water treatment during storage of quail eggs is not related to the treatment method (immersion treatment or spray treatment) but is closely related to the treatment concentration.

Summarizing the above results, it can be seen that when the electrolytic alkaline water is treated to quail eggs in the range of the stock solution to 1/100 diluent, there is at least twice as long storage effect.

As described through the above embodiment, when the electrolytic alkaline water solution to 1/100 diluent is sprayed or immersed in quail eggs for storage, there is an excellent effect in extending the shelf life of the quail eggs, and further coating treatment after the spray or immersion treatment. If through, there is an excellent effect of further improving the shelf life of quail eggs, which is a very useful invention in the food industry.
