Abstract

PURPOSE:To improve growth promoting effect, by using an L-ascorbic acid higher fatty acid ester having stability in a feed as a vitamin C source to be blended with a feed for rearing an aquatic animal. CONSTITUTION:A feed for rearing an aquatic animal, consisting of white fish meal, defatted powdered milk, a soybean cake, animal or vegetable fats and oils, etc. is blended with about 0.04-0.25wt% L-ascorbic acid higher fatty acid ester, to give the titled feed. Palmitic acid, stearic acid, oleic acid, linoleic acid, etc. may be preferable as the higher fatty acid, and in the addition of the L-ascorbic acid higher fatty acid ester, it is dissolved in animal or vegetable fats and oils for rearing an aquatic animal and preferably added to the feed. The L-ascorbic acid higher fatty acid ester is different from vitamin C, has more improved stability in the feed, and converted into vitamin C in the body of reared aquatic animal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice cake for aquaculture containing L-ascorbic acid high grade 1]f8T ester as an active ingredient.

In recent years, along with the development of aquaculture resources, feed for the zone has been researched and developed, and V (<
, white fish meal, skim milk powder and other animal raw materials, soybean meal, pregelatinized starch, al7al7amyl and other fine raw materials, animal and vegetable fats and oils, minerals, vitamins, M1 oxidizing agents, color enhancers Nutrients necessary for the breeding of Shinyo Chisui Rumor-1 are included according to the type of aquatic animal being fed. Its forms include clan 1,
Types include pellets, mash, or powder.

Among the WIL nutrients contained in water ψ machimonoryouri feed, ascorbic alcohol (vitamin C) is found at high temperatures.

Ascorbic acid is easily destroyed by high humidity or pressure and decomposes during the manufacturing process or during storage, so it is coated or made into calcium salts, but ascorbic acid decreases (decomposes) during feed processing and storage. The results of the tests on the lids are shown in Table 1.

The trial was ascorbine fi!, which was coated with casein using shrimp feed (Matsushu). 1toO～-
Feed mixed with (referred to as A), and feed mixed with 500 dah of ascorbic acid coated with beef tallow (referred to as B),
The test was carried out on a feed (referred to as C) mixed with calcium ascorbate. After storage means that it has been stored at 37℃ for 15 days. I tried coating it with beef tallow, but none of them made much of a difference, and the effects were only modest.

In addition, 5 ooqs of ascorbic acid was added to the shrimp feed (
Table 2 shows the results of an ascorbic acid reduction test during high-temperature storage of feed prepared by pelletizing Matushu feed mixed with Matushu (Japanese matshu).

Table 2 Decrease in ascorbic acid during feed storage As shown above, ascorbic acid is a concern during feed production and storage, so when producing feed, it is necessary to anticipate its decomposition in advance and include it in a higher amount than necessary. We are letting them do so.

The present inventors have developed a nutrient that does not decompose during the manufacturing process or storage, and does not elute into water during feeding, and has the same effect as calcium ascorbate or G'J As a result of research, the present invention was achieved by finding that monoascorbic acid higher fat ester, which is a derivative of ascorbic+V, exhibits the same effect.

The object of the present invention is to provide a feed for breeding water containing L-ascorbic acid higher fatty acid ester.

The present invention is a feed for breeding aquatic animals containing L-ascorbic acid high fat 1 [h* ester] as an active ingredient.

In addition, the present invention provides that L-ascorbic acid high grade tth fat ester is added to Suiken Animal Breeding Copper Family from 004 to 0.25.

Furthermore, the present invention provides that L-ascorbine 1-lead higher fatty acid ester is added to 11 tJ of animal and vegetable oil for aquatic animal cultivation.
This is a feed for cultivating aquatic animals, which contains 41 to 5 CH(A).

means lauric acid, etc. In addition, when L-ascorbine version AiI diaphragm ester is mixed with feed as it is, it mixes with calcium ascorbate in almost the same way, but for example, L-ascorbic acid ester G
It is impractical because it is expensive (a lot cheaper than calcium ascorbate). However, if you use a mixture of animal and vegetable oils and fats for aquatic animal culture (e.g., squid oil, soybean oil, fish oil, etc.) (for example, squid oil, soybean oil, fish oil, etc.) and is well absorbed.

Next, ascorbic acid higher IJ fatty acid ester,
Ascorbic acid stearate was used, and as the feed, shrimp artificial bait HE was used, and as the animal fat and oil, squid oil was used, and ascorbic acid higher
Table 3 shows the results of tests conducted on the effects of fat-intoxicating esters.

Table 3 Kuruma Shrimp Reproduction Survival Rate Test This trial b2 was conducted in tank 701. At a water temperature of 28-30℃, 37
This is the result of 4-day multiplication, and the value is the 3-water elliptical average value.

However, in the additive-free area, 2 tanks are uniformly mixed. The oil containing ascorbic acid and stearic ester was obtained by thoroughly mixing 2 t of ascorbic acid stearate with squid oil, and then adding 2% gIk to artificial shrimp feed. This is a feed containing female ester.

Regarding the above test, the product of the present invention 41 showed an excellent survival rate, but in addition, the amount of ascorbic acid contained in the body of the shrimp was measured after the test was completed, and the results are shown in Table 4. .

According to Table 514, "This test", it was clearly recognized that ascorbic acid stearate was converted to ascorbic acid in the body of the shrimp. Furthermore, shrimp fed with 0.3% and shrimp fed with 0.04% had approximately the same ascorbic acid content. Incidentally, similar effects are observed with ascorbic acid higher fatty acid esters made of other higher fatty acids. Even if expensive ascorbic acid higher fatty acid ester is used, it is possible to achieve the same effect as ascorbic acid with a small number of companies using it.

The ascorbic acid stearate used here is a white crystalline powder 7', a monoester in which the OH group of the 6th carbon of L-ascorbic acid and the COOH of stearic acid are bonded. The melting point is 115-118℃, and it is soluble in ether and ethanol, but it is soluble in animal and vegetable oils.
It melts slightly. This product undergoes less decomposition during processing than calcium L-ascorbate. In addition, since it is almost insoluble in water, for example, when applying Mm to shrimp, it will not elute even 1° between the time of feeding and the time of feeding by the shrimp. Calcium ascorbate is easily soluble in water, and if the weight at the time of feeding is 100, it will decrease to 57.8% at 1 o'clock.Also, if it is dissolved in water when feeding, adsorbed to pellets and then fed. It decreases to 31, 31 in an hour.

Next, Table 5 shows the results of a recovery test of ascorbic acid from artificial shrimp feed containing calcium ascorbate and ascorbyl stearate, respectively.

Table 5 Next, as L-ascorbic acid higher fatty acid ester,
Although L-ascorbic acid stearic acid is used as feed for aquatic animal culture), and [, the T phase is described using feed for shrimp honkoi, other high-grade fats can also be used. Also other aquaculture feed (carp.

It can also be used as aquaculture feed for sweetfish, yellowtail, eel, rainbow trout, crab, and other aquaculture. The effects of L-ascorbic acid higher fatty acid ester are similar.

Embodiments of the invention are described.

Example I L-ascorbic acid stearate 2? and 2 r of sorbitan monooleate (Span 80) were mixed, and then 100 ml of purified squid oil was mixed and emulsified using a homogenizer. The obtained feed was added to a commercially available shrimp compound feed.
This was fed to the prawns.

Example 2 2 vol of L-ascorbic acid stearate was dissolved in 5 d of ethanol and further kneaded with sorbitan monolaurate (Span 20) 29, followed by adding 100 ml of squid oil and mixing homogeneously.

The obtained feed was trivalently added to a commercially available shrimp compound feed and fed to the shrimp L7e.

Example 3 L-ascorbic acid stearate 4002 and sorbitan monooleate 400 f/wt were mixed well, and further 20 J of purified squid oil was added and stirred to emulsify well.

After uniformly mixing the above-mentioned emulsified oil with a commercially available shrimp feed ground into imitation powder, 301 water was added and mixed homogeneously, and then this mixture was mixed using an Anderson extruder with a W diameter of 3 ml. Acid mold is made into a cylindrical long pellet with a length of about 15 pieces, and this is dried at about 80℃ using a dryer.
The prawn feed was dried at a temperature of about 980 Ky to obtain shrimp feed.

Example 4 Mix 5v of L-ascorbic acid stearate and 5f of sorbitan monooleate well, add feed oil (Riken Vitamin W) toomz, emulsify with a homogenizer, and add 5% of the obtained product to the shrimp compound feed. This was adsorbed and administered to tiger shrimp.

The present ester is difficult to dissolve in water during processing and storage of pellets, etc., and is particularly stable when mixed with animal fats and oils. ) is more stable than those containing calcium ascorbate, and the ascorbic acid derivatives are converted to ascorbic acid in the bodies of cultured aquatic animals, making it possible to obtain extremely useful aquatic Q+ animal culture feed.
