Abstract

PROBLEM TO BE SOLVED: To obtain a highly safe naturally colored biodegradable lure by coloring a lure made of konjak mannan (made from arum root) with food dyestuff, then immersing the lure in organic acid buffer liquid and fixing the dyestuff. SOLUTION: At a room temperature, eight pieces of molded biodegradable lures (about 28g) made of konjak mannan are added immersed for 15 hours in the aqueous solution consisting of 43ml of 0.3% aqueous solution of No.3 food dyestuff and 7ml of water adjusted to weakly alkali side, for example. Next, the colored biodegradable lure is speedily cleaned in 50ml of water at the room temperature after drain, and non-fixed coloring matter stuck on the surface is removed. Afterwards, at the room temperature, the colored degradable lure is immersed for about 4 hours in 50ml of a citric acid buffer liquid adjusted to pH4, washed with water after the fixture of the dyestuff to be colored in red to obtain the objective lure.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to storage stability by coloring a biodegradable artificial bait made from konjac mannan with an edible pigment, immersing it in an organic acid buffer, and coloring and fixing the pigment. Also, the present invention relates to the provision of a biodegradable artificial bait which is environmentally friendly by stabilizing discoloration prevention in water, is easy to handle, and has a long-term retention of pigment.

2. Description of the Related Art Along with today's leisure boom, fishing has been widely popularized among hobbies and entertainments. Above all, lures (simulated baits) have been increasingly used in a wide range of ages due to their ease of use and ease of use. On the other hand, there has been a series of accidents in which disposable lures remain as they are in the body of the fish due to the heating of the boom, and fishing lines remaining with the lures left unattended due to roots or the like become entangled with the feet of water birds. Biodegradable artificial baits that are degraded by microorganisms in nature to improve the adverse effects on the environment have been attracting attention. For example, Japanese Unexamined Patent Publication (Kokai) No. 62-190037 discloses a gel composition for artificial bait based on a polysaccharide and a polyvalent metal compound, which is similar to animal bait.
It is inferior in shape retention and safety that can withstand underwater or seawater use, and particularly in the retention of pigments that affect the attracting effect among fish attractants. JP-A-63-120366 discloses that a gel composition obtained by mixing and adding a fish group attracting substance such as silkworm pupa powder, a coloring agent and the like to konjac potato fine powder containing konjac mannan as a main component, and then alkali-treating. After the treatment, fishing baits of various shapes and / or various packaging forms and methods of manufacturing the same are disclosed. However, konjac mannan is colored before coagulation, and the colorant is stabilized by coagulation and steaming after alkali treatment, but the fixation of the colorant is not fundamentally stabilized, and In coloring, it is difficult to freely adjust the color to resemble various animal baits, and there is a disadvantage that the performance as a fishing bait is remarkably reduced.

DISCLOSURE OF THE INVENTION The present invention relates to a method for producing a biodegradable artificial bait, which can be used as an edible pigment as a food coloring in a coloring method for the purpose of maintaining coloration very similar to raw bait for a long period of time. A highly safe and nature-friendly colored biodegradable pseudo, characterized by coloring and immobilizing a biodegradable pseudo bait made from konjac mannan using a pigment and / or a natural pigment without deteriorating the quality of the biodegradable pseudo bait. To provide food.

The inventor of the present invention has conducted various studies on a coloring method capable of maintaining coloring that is very similar to raw food for a long period of time. As a result, konjac mannan was added to an aqueous solution of an edible dye adjusted to be slightly alkaline. A simulated bait made of immersion is used to immerse the pigment in the dye, and the buffer is adjusted to pH 3.8 to 4.5 with an organic acid and disodium hydrogen phosphate, preferably to pH 4.0 to 4.3. A coloring method which can achieve the object of the present invention by immersing in a buffer solution thus obtained has been found.

[0004]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the method for immobilizing a biodegradable artificial bait of the present invention by coloring will be described in detail. The konjac mannan used in the present invention may be any of red stalk type of konjac potato, most commonly cultivated konjac potato, green stalk type, sina type, etc., from which konjac potato flour usually used as edible konjac is used. be able to. This konjac potato flour is used as a material, and the silkworm chrysalis powder, fish oils,
Taste and odor stimulants such as fish meal and fish odor substances, visual stimulants such as fluorescent substances, and, if necessary, coloring and preservatives are added and mixed. A solid bait is obtained by solidifying and molding in a mold of similar shape and size. The coloring agents used in the present invention are legal food tar dyes and natural pigments used as food additives, and those preferably used as the legal food tar dyes have color index numbers of C.I. I. 45430
(Edible red No. 3), C.I. I. 45410 (edible red 10
No. 4) and C.I. I. Xanthenes such as 45440 (edible red No. 105). Also, gardenia yellow pigment (crocetin), gardenia blue pigment, annatto pigment, and the like can be suitably used as natural pigments. More desirably, these legal dyes for food use and natural dyes are suitably blended and used, and their concentrations and hues can be freely changed and adjusted to match the color of various animal raw foods. The color of the biodegradable pseudo bait made from konjac mannan can be added and colored together with other fish attractants before coagulating konjac mannan. Post-coloring is preferred, and can be easily carried out by immersion in a weakly alkaline aqueous solution of the above dye at room temperature. Examples of the organic acid used in the present invention include citric acid, tartaric acid, malic acid and fumaric acid,
Particularly, citric acid is preferred. The coloring and immobilization of the dye of the present invention is carried out with an organic acid and disodium hydrogen phosphate at a pH of 3.8 to 4.
This is carried out by immersion in a buffer solution adjusted to pH 5, preferably pH 4.0 to 4.3 at room temperature for 3 to 7 hours. Particularly, a buffer solution adjusted with citric acid and disodium hydrogen phosphate is preferred. When the pH is 3 or less, the dye can be immobilized but the color disappears slightly, and the quality is particularly deteriorated, which is not practical. When the pH is 5 or more, no deterioration in quality is recognized, but the elution of the dye is large and the desired performance cannot be obtained.

[0005]

The present invention will be described in more detail with reference to the following examples. [Example 1] 43 ml of an aqueous solution of 0.03% edible red No. 3 [manufactured by Eisen Co., Ltd.] adjusted to slightly alkaline and 7 ml of water
Of the konjac mannan material were added at room temperature and immersed in the solution for 15 hours. After coloring, the biodegradable artificial bait should be
Wash immediately with 0 ml to remove uncolored dye adhering to the surface, and then adjust to pH 4 50 ml of citrate buffer (160 ml of 2% aqueous citric acid and 40 ml of 7% disodium hydrogen phosphate) The biodegradable artificial bait colored in was immersed at room temperature for 4 hours, and after immobilizing the pigment, it was washed with water and colored red. After immersing eight of the obtained colored biodegradable pseudo baits in a large amount of water and seawater at room temperature for 1 hour, 3 hours, and 5 hours, the colored biodegradable pseudo bait was taken out, ground sufficiently, and weakly alkaline water was added. The remaining dye was extracted by using, and colorimetry was performed with a spectrophotometer to calculate the remaining dye ratio. As a result, the color-immobilized biodegradable pseudo bait did not deteriorate in quality, and the dissolution test in water or seawater was remarkably superior to the unfixed pseudo bait as shown in Table-1.
