It will be reduced to ~ 45%, and profitability will be extremely reduced. (B) Since the crude protein and crude fat in the squid viscera are concentrated and separated by heating, the acid value of the fat is increased, which causes the lipid to be converted to peroxidized fatty acid and become toxic, resulting in deterioration of quality. Invite. (C) Squid internal organs contain a large amount of unsaturated fatty acids (omega-3)
Is included, which helps the growth of living things. In particular, cholesterol (chol, which is essential for the growth, growth, and molting of shrimp)
esterol) is contained in a large amount, but its components are drastically reduced during the heating and concentration process. (D) Squid internal organs have a peculiar odor particularly favored by shrimps (crustaceans), but the components thereof are drastically reduced during the heating and concentration process. (E) Since the production process is extremely complicated and a large amount of facility cost investment is required, a large amount of time and cost are consumed and the manufacturing cost becomes high. As described above, the conventional feed additives produced by using squid viscera as the main raw material have many disadvantages that occur in the process of heating and concentrating, and thus have a drawback that rapid growth of fish farming, especially shrimp cannot be expected. It was

EXAMPLES The present invention will be described in more detail with reference to examples below, but the invention is not limited thereto. (Example 1) After thoroughly cleaning the bacteria attached to the squid viscera, which is a raw material, the temperature of 37 to 40 ° C was maintained for 6 to 7 days to spontaneously perform fermentative decomposition to generate an amino acid, which was the target. A feed additive was produced. In addition, fat containing a large amount of unsaturated fatty acids was not separated and contained in the squid internal organs. These components promote the growth of organisms. In addition,
This method has low economic efficiency and is not suitable for mass production.

(Example 2) This is a method of accelerating the fermentation action by culturing and feeding a squid viscera as a raw material with a fermentation accelerator. Specifically, 100% by weight of squid viscera thoroughly washed with various bacteria, 5-10% by weight molasses, 10-soybean meal
After adding 20% by weight and heating at a temperature of about 80 ° C. (75 to 85 ° C.) for 10 to 15 minutes, the mixture is heated to 35 to 40 ° C.
After cooling, the complex lactic acid bacterium was added in an amount of 7 to 10% by weight to accelerate the enzymatic reaction and perform fermentation decomposition. After a lapse of about 5 to 7 days, sterilization was performed at about 80 ° C. to produce a target feed additive.
The addition amount of the complex lactic acid bacterium is not limited to the above, and is 5 to 20% by weight, especially 5 to 15% by weight based on 100% by weight of the squid internal organs.
Weight% is sufficient. In addition, the addition amount of the complex lactic acid bacterium in the example of the present invention was 10 ⁷ (CEL
L) / ml.

(Example 3) The squid viscera as a raw material was heated at a temperature of about 80 ° C for 10 to 15 minutes to sterilize various bacteria, and then cooled to 40 ° C to obtain 100% by weight of the squid viscera. After adding 10% by weight of lactic acid bacteria and stirring well, the enzyme action is caused to occur at room temperature for 5 to 7 days, followed by sterilization at a temperature of 80 ° C for 10 to 15 minutes and returning to room temperature to obtain the target feed additive. Manufactured. This method is preferably used when the freshness of squid offal, which is a raw material, is relatively poor.

(Example 4) 30% by weight of 100% by weight of squid viscera as a raw material was mixed with 20% by weight of soybean meal and 10% by weight of complex lactic acid bacteria, and after thoroughly stirring, the remaining amount of squid viscera. 70% by weight was added to cause an enzyme action, and subsequently, heat sterilization was performed at a temperature of 80 ° C. for 10 to 15 minutes to produce a target feed additive. This method applies when higher protein is needed as a feed additive. It is also possible to additionally add 20 to 35% by weight of finely ground soybean meal to this product to produce an almost powdery product.

(Example 5) 20% by weight of squid viscera powder, and 10% of complex lactic acid bacteria to 100% by weight of squid viscera as a raw material
After the weight% was put into a closed container at room temperature and fermented, the mixture was heat-sterilized at a temperature of about 80 ° C. for 10 to 15 minutes to produce a target feed additive. This method is used for imparting a more intense odor characteristic of squid internal organs, and is mainly suitable as a shrimp feed additive. The content of the squid viscera powder is optimally 20% by weight, but it is applicable as long as it is about 15 to 25% by weight.

[0012] As in the above examples, the manufacturing method for achieving the technical problem of the present invention has many modes, but the common feature is that the squid internal organs are not heated and concentrated, and the addition of complex lactic acid bacteria or the like is added. It is effective for fish farming because the lipids do not cause a peroxidation reaction and the protein is decomposed to the constituent amino acids by enzymatically fermenting the higher proteins in the squid viscera by appropriately adding agents to decompose them by fermentation. Various chemical substances can be made, and the feed effect can be increased. In addition, it can retain abundant unsaturated fatty acids omega-3 (DHA, EPA), which are essential in the growth process of organisms, especially cholesterol essential for molting of shrimp.

Scientific considerations regarding the effective chemicals contained in fish feed suggest that the following components are relevant to many fish preferences. That is, the main substances include amino acids, nucleic acid-related compounds, and lipids, as well as basic nitrogen compounds, organic acids,
Carbohydrates, proteins, etc. are supplementarily related. A protein is a substance in which several hundred or more amino acids are bound.

Regarding the feed value for fish, it is included in the feed because five sensory organs, that is, olfactory, taste, auditory, visual and tactile sensations are complicatedly involved and become important factors of feed preference. The composition of chemicals plays the most important role. Therefore, the present invention is the most desirable method for producing a feed additive, which is capable of enzymatically degrading the main component protein to amino acids while maintaining abundant unsaturated fatty acids and cholesterol without losing lipids. is there.
