[Industrial Application Field] The present invention relates to a freshness preserving agent and freshness preserving method for fresh foods, flowers, and other perishables, which can be used in processing, storage, distribution processes, or even at home. [Conventional technology] Traditionally, cabbages, spinach, bean sprouts, burdock, garland chrysanthemums, raw shiitake mushrooms, apples, mandarin oranges, pears,
Fresh foods such as strawberries, peaches, pineapple, bananas, etc. and ornamental flowers (hereinafter referred to as ``fresh foods'') are
Efforts are being made to preserve the freshness of food by preserving it by refrigeration, freezing, or soaking it in water or salt water, or by shortening the time required for distribution by shipping directly from the farm. There is no simple and effective way to preserve the freshness of perishables. [Problem to be solved by the invention] In the specification of this application, "freshness of fresh food" means
Color tone, shape, volume of fresh produce at the time of collection,
It refers to the degree to which flavor, odor, moisture content, etc. are maintained. On the other hand, if freshness is lost, perishables may experience changes in color such as blackening or browning, changes in shape or volume such as wilting or shrinkage, deterioration of flavor or odor, water leaching, spoilage, etc. However, if the occurrence of these phenomena is small compared to the time that has passed since harvesting, it is said that the freshness is well preserved. Conventional freshness preservation methods such as refrigeration, freezing, or immersion in water or salt water have not been sufficiently effective in preserving freshness, and in some cases have significantly lowered the value of the product. Furthermore, efforts to preserve freshness during the distribution process, such as direct delivery from the production area, require a certain amount of cost because the distribution process does not require large-scale or mechanized production, and is not suitable for producers who do not have the means of distribution. It was something that wasn't there. Furthermore, producers and buyers have desired a simple method for preserving freshness that can be processed in farmers' gardens before shipping. In addition, at home, methods such as soaking in water or salt water have been used to preserve peeled fruits, etc., during cooking, but this is not an adequate preservation method, and There were problems such as discoloration, browning, and wilting. The purpose of the present invention is to solve the above-mentioned problems by using cabbage, spinach, bean sprouts, burdock, garland chrysanthemum, fresh shiitake, apple, pear, mandarin orange,
The purpose of the present invention is to provide a freshness preservative and a freshness preservation method for fresh foods such as strawberries, peaches, and pineapple, and ornamental flowers. [Means for Solving the Problems] The present invention provides a freshness preservative for fresh produce containing kojic acid as an active ingredient, and also includes soaking fresh produce in an aqueous solution containing kojic acid or soaking the fresh produce in an aqueous solution containing kojic acid. The present invention aims to solve the above-mentioned problems by providing a method for preserving the freshness of fresh produce, which is characterized by spraying the aqueous solution. For this reason, the present inventor has developed cabbage, spinach,
Regarding freshness preservatives for fresh foods such as bean sprouts, burdock, garland chrysanthemums, raw shiitake mushrooms, apples, pears, mandarin oranges, strawberries, peaches, pineapple, and ornamental flowers, they are safe (non-toxic), water-soluble, and in trace amounts. Effective substances were searched for in various natural substances. As a result, they discovered that kojic acid, which is contained in koji used in sake, miso, soy sauce, etc., has a remarkable effect on preventing deterioration of freshness. By using this kojic acid to preserve the freshness of fresh produce, it is possible to maintain the fresh color and flavor of fresh produce over long periods of time, and to effectively prevent "wilting" of fresh produce. . Furthermore, various nutrients such as vitamins and fatty acids can be sufficiently retained without any loss. The amount and effectiveness of kojic acid depends on the type of perishables to be used, the time of collection (season), and the condition of the perishables (time since collection, in the case of fruits, whether they are peeled or not). It varies depending on the amount, but from 0.001 to
Preferably, a 5.0% by weight aqueous kojic acid solution is used in direct contact with fresh produce. Since kojic acid is a natural substance that is harmless to living organisms, there is no restriction on the amount used, but if it is used at a concentration of 5.0% by weight or more, fresh produce may be colored pale yellow. First, farmers who produce vegetables, fruit trees, gardening, etc., spray an aqueous solution of kojic acid on fresh produce before and after harvesting, or when shipping.
Freshness can be preserved. Also, during transportation, storage in warehouses, and processing at factories, freshness is maintained by spraying an aqueous solution of kojic acid on fresh produce, or by immersing the produce in the aqueous solution or syrup containing kojic acid. can be saved. Furthermore, it can be easily sprayed over the counter at markets, general supermarkets, retail stores, etc., or it can be sprayed at regular intervals by installing an automatic sprinkler-type sprayer inside the store, open or closed refrigerators, or storage rooms. It can be sprayed to preserve the freshness of perishables. Of course, it can also be used in a similar manner in home refrigerators, kitchens, etc. In the case of peeled fruits, etc., it is also effective to soak wrapping paper (including synthetic resin ones) in an aqueous kojic acid solution in advance, and then bring the wrapping paper into close contact with the cut end of the fruit. [Effects of the Invention] The freshness preservative and freshness preservation method of the present invention reduce changes over time in the color tone, shape, volume, flavor, odor, moisture content, etc. of collected fresh produce, and are effective. Moreover, the freshness of perishables can be easily preserved. [Example 1] Fresh shiitake mushrooms were mixed with water (control), 1.0 wt% sucrose aqueous solution, 1.0 wt% sodium chloride aqueous solution, 0.1 wt% kojic acid aqueous solution, and 1.0 wt%
Soak in kojic acid aqueous solution for 5 minutes. After removing moisture on filter paper for 5 minutes, put it in a plastic case with filter paper underneath and leave it at room temperature (20℃).
Even when observed after a period of time, those treated with kojic acid had better retention of the overall shape, shape, and volume of the bacterial folds than those soaked in water (control). Those soaked in water (control) were completely wilted even after 24 hours, and the shape of the fungal layer changed. Also
The above-mentioned freshness preserving effect was not observed with a 1.0 wt% sucrose aqueous solution or a 1.0 wt% sodium chloride aqueous solution, and those immersed in a 1.0 wt% sucrose aqueous solution showed the same degree of wilting as water (control). However, immersion in an aqueous sucrose solution caused early discoloration (sometimes the fungal folds turned black). The differences in these changes became clearer as the days passed, and those treated with kojic acid had a different shape compared to water (control), 1.0 wt% sucrose, and 1.0 wt% sucrose.
Compared to treatment with a wt% sodium chloride aqueous solution, the shape and volume were maintained better, and discoloration was also prevented. A similar effect was also obtained by spraying an aqueous kojic acid solution (see Table 1 and Figure 1).

170g of commercially available spinach was soaked in water (control), 0.1% by weight kojic acid aqueous solution, and 1.0% by weight kojic acid aqueous solution for 5 minutes, and after removing moisture on filter paper for 5 minutes, it was placed in a synthetic resin bag and kept at room temperature. (20℃). Even when observed after 24 hours, the kojic acid-treated products showed less wilting and discoloration compared to water (control) and maintained freshness. The difference in this phenomenon became clearer as the number of days increased, and when observed after 4 days, those treated with water (control) wilted and melted. As a result, the volume was about half that of those treated with kojic acid, and there was also discoloration and a strong odor. On the other hand, as shown in Table 2, those treated with kojic acid had fewer of these phenomena and maintained freshness. When observed after 4 days, the eluted water was measured and found to be 34 ml in water (control), 17 ml in 0.1 wt% kojic acid, and 13 ml in 1.0 wt% kojic acid (see Table 2).

Then, lightly drain the water, put it in a synthetic resin bag, and leave it at room temperature (20℃). Even when observed after 24 hours, the freshness of the kojic acid-soaked vegetables was preserved compared to that of the water (control). The difference became clearer as the number of days increased, and when observed after 4 days, the ones soaked in water (control) were wilted, discolored, and had a stronger off-odor. On the other hand, those treated with kojic acid had less wilting and discoloration, and had less off-odor than water (control). A similar effect was also obtained by spraying a kojic acid aqueous solution (see Table 3).
