DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a germicidal detergent composition for fresh food.

[0002]

2. Description of the Related Art In the distribution process of agricultural products such as vegetables and fruits, and marine products such as fish and shellfishes, washing is performed in addition to processes such as harvesting, sorting and packing. At that time, the detergent used contains a surfactant, a bleaching agent, etc., but the components are limited because the object is a food. When immersion in such a cleaning agent is not sufficient, cleaning is performed by spraying a pressurized water stream onto the object.

[0015] Of the so-called electrolytic oxidized water obtained by the diaphragm method, hypochlorous acid water (pH (2
(5 ° C) 2.7, effective chlorine concentration 50 ppm)
The pH was adjusted to 11 with a 1 mol / L aqueous sodium hydroxide solution to obtain a composition of Comparative Example 4 in Table 1. Further, after adjusting the pH of the above hypochlorous acid aqueous solution to pH 5 with a 1 mol / L aqueous solution of disodium succinate, lauryl dimethylamine oxide (the same as in Example 1) was added so that the concentration became 25 ppm. The composition of Example 6 was obtained.

The effective chlorine concentration in Table 1 is based on JIS
It is measured by K-0101 "Iodine method".

Using a test aqueous solution obtained by diluting these compositions to have the effective chlorine concentration shown in Table 1 (Examples 6 and Comparative Example 4 use the compositions as they are), the following methods were used to remove bacteria.
A sterilization performance test was performed. Table 1 shows the results.

(2) Evaluation of sterilization / sterilization performance Two skins of a commercially available cabbage are peeled off, divided into four parts, and cut into pieces of about 100 g. The leaves were placed in a 1 L beaker such that the leaves were peeled off one by one. The composition shown in Table 1 was added thereto so that the bath ratio was 10, and immersion washing was performed for 3 minutes.
Two 0 second pool rinses (1 L of tap water) were performed. All of these operations were performed at room temperature. After the last rinsing, the cabbage is homogenized to obtain a sample for measuring the number of bacteria. N number is 5
The number of general viable bacteria per 1 g of cabbage was measured according to the food hygiene inspection guidelines. The eradication / sterilization rate was calculated from the following equation. Bacteria removal / sterilization rate (%) = [(AB) / A] × 100 A; number of bacteria before washing (cells / cabbage 1 g) B; number of bacteria after washing (pieces / cabbage 1 g)
