Means for Solving the Problems As a result of intensive studies, the present inventors have found that a water-soluble solid having a specific melting point and specific gravity and krill, and / or the remaining edible portion of crab and shrimp [dried product and And / or raw (frozen)] [hereinafter abbreviated as crab and shrimp raw material, dried product and / or raw (frozen) crab and shrimp raw material] or / and excipient, and the processed krill And / or crab
It has been found that the processed product of the remaining edible portion of shrimp (hereinafter abbreviated as crab / shrimp processed product) is effective in preservation, and that it is easily settled in water as a sowed bait / feed, and has reached the present invention. That is, the present invention melts the remaining edible portion of dried krill and / or dried crab and shrimp, melting point 40 ° C. or more,
Melt-mixing with a water-soluble solid having a specific gravity of 1.02 or more;
Alternatively, the remaining edible portion of raw (frozen) krill or undried crab and shrimp may be mixed with the molten water-soluble solid while dewatering, or dried or raw crab and shrimp raw materials may be used. Irrespective of whether or not it is used, a water-sedimented crab / shrimp processed product which is preferable as a room-temperature-preservable sow bait / feed, which is characterized by melt-mixing the excipient and the fish inducer with the water-soluble solid. The present invention relates to a method for producing the same, and a method for collecting fish utilizing the property of a crab / shrimp processed product which has once settled to resurface with the passage of time.

The water-soluble solid used in the present invention includes D-sorbite, which has low hygroscopicity and deliquescence, and has a melting point of 75 ° C. and is stable even in summer. Specific gravity is 1.654
Since the specific gravity of seawater is 1.02, it sinks when sprayed on the sea surface. It is chemically neutral, non-corrosive, slightly sweet in taste, and is presumed to be a favorable taste for fish. Specific water-soluble solids other than D-sorbit include 1,4-sorbitan,
Saccharides such as glucose, maltose, fructose, and sucrose, such as 2,5-sorbitan, 3,6-sorbitan, sorbide, and pentaeryth; polyethylene glycol having a molecular weight of 3,000 to 500,000; [sorbitol, sorbide, sorbitan, lower grade High ethylene oxide adducts of alcohols, phenols, and substituted phenols (for example, nonylphenol, octylphenols, and lower hydroxy compounds). Further, as a modifier for the water-soluble solid, a sizing agent such as CMC, starch or polyvinyl alcohol, or a water-absorbing polymer which is a reaction product of starch and acrylonitrile can be used in combination. Particularly preferred D-sorbitol among the above water-soluble solids slightly differs according to the literature, but the melting point is 75 ° C. for hydrate, 92 ° C. for metastable type and 97 for stable type.
It is the optimal melting point for dehydration melting at 110-112 ° C in anhydrous and anhydrous. In addition, the specific gravity is 1.654, which is remarkably large as an organic substance, and the impregnated substance is easy to settle, which is preferable. It is presumed that sorbitans and sorbide as related compounds also have similar properties. The amount of the water-soluble solid used is 10 parts by weight per 100 parts by weight of the dried krill, crab and shrimp raw materials.
0 to 500 parts by weight, preferably 100 to 300 parts by weight. When crab and shrimp raw materials are not used, the ratio of the excipient and the water-soluble solid is 1: 1 depending on the type of excipient.
00 to 100: 1, preferably 1: 1 to 1: 3. The shape can be changed from granular to massive depending on the purpose of use.

Examples of the excipient used together with the water-soluble solid containing or not containing the raw material of the present invention include rice bran, wheat bran, soybean meal, beans made from oil extracted from beans, and the like. Corn and popcorn, okara, dried okara, wood sawdust, wood flour and other organic substances, kaolin, diatomaceous earth and other inorganic substances, and mixtures thereof can be mentioned. Can be used alone (in combination with fish inducers). [That is, excipients, fish inducers, water-soluble solids (eg, rice bran,
Mixed melt of sodium glutamate and D-sorbitol)

The penetrant used in combination with the water-soluble solid of the present invention is preferably an anionic or nonionic. Jee
Examples thereof include 2-ethylhexyl-Na-sulfosuccinate (Sammorin OT-70, manufactured by Sanyo Chemical) and polyoxyethylene glycol alkyl ether (Sanmorin 11, manufactured by Sanyo Chemical). The amount of the penetrant used is from 0.01% to 2%, preferably from 0.05% to 2%, based on the water-soluble solid.
1.0%. Other preferred additives include attractants that attract fish (for example, amino acids such as glutamic acid, inosinic acid, taurine, glycine, proline, lysine, tryptophan, and alanine; peptides of condensates of these amino acids; krill-enriched extract) , Shrimp concentrated extract, trolocob, squid oil, etc.) and garlic as a preservative can be added to further improve the performance as a sow bait. Glutamic acid and extracts are preferred.

As the raw material for crab and shrimp of the present invention, any of seafood and river products can be used. Both edible and non-edible portions can be used and are available as dry and fresh or frozen products. A typical dried product is dried krill. Hereinafter, the present invention will be described by using the dried krill as an example. This product is obtained by freeze-drying raw krill, manufactured by the usual freeze-drying method, and has almost no moisture. For this reason, the cavity in the body of the dried krill contains air, and the air becomes a floating bag and does not settle in the water when sprayed on the water surface. When the water-soluble solid is heated above its melting point and dry krill is injected into the hot liquefied solid, the air inside the cavity is heated and expelled, and the liquefied solid enters instead of air I do. The solid matter liquefied from the treated dried krill is shaken off while heating, or centrifuged while hot, and allowed to cool to room temperature, and wait for the solidification of the water-soluble solid matter to obtain a product. The crab / shrimp raw material content of the dried crab / shrimp product is 20 to 35% by weight, depending on the conditions of hot centrifugation, and can be adjusted by the conditions of hot centrifugation. In the case of a hygroscopic / deliquescent water-soluble solid, or a water-containing crab / shrimp raw material, heat-mix with a molten water-soluble solid in the presence of a desiccant or dehydrating agent, and if necessary, reduce the pressure. The dehydration mixing and cooling are performed below.

The crab / shrimp processed product impregnated with the water-soluble solid material of the present invention is a product group in which one crab / shrimp raw material can be visually recognized, and one / one is independent. It is roughly divided into a group of roughly crab and shrimp processed products that are close to granules of a suitable size, but they are somewhat impregnated with water-soluble compounds, so they have some hygroscopicity. You also need to be careful. For example, it packs with moisture-proof packaging for each use amount. Attention must be paid to the same level as for dry foods, such as by enclosing an oxygen absorber in each pack.

The raw material of frozen or raw crab and shrimp is usually 7
It is a hydrate of 0 to 90%. In this case, the water-soluble solid is heated to a temperature of 100 ° C. or higher, which is higher than its melting point, and a frozen product or raw material is added little by little, and the mixture is slowly stirred. The contained water evaporates as steam. At this time, it is desirable to reduce the pressure. Although it takes longer than a dried product, almost the same target product can be obtained. In order to promote the evaporation of water, an azeotropic solvent such as ethanol, which azeotropes with water, is added and heated, and water is distilled off as an azeotropic mixture, and finally the azeotropic solvent is also distilled off.

Hereinafter, the present invention will be described with reference to examples.
