Description

Abalone Peeler Composition {Composition for Peeling Abalone Off}

 The present invention relates to a peeling composition useful for separating abalone, in particular abalone plaque, from aquaculture plates, farming places and the like.

The culture tank structure of abalone nursery is generally composed of broo line (air supply) at the bottom, shella that allows hatched abalone plaques to be attached and live food on the shella (diatom culture for abalone). . In the abalone nursery, the eggs of the abalone are hatched in a breeding tank and reared for a certain period of time. At this time, the raised abalone patches are separated from the shella and the bottom and sorted by size, and then grown for a certain period of time. Will be sold.

At this time, the abalone plaque should be peeled off from the shell, floor, etc. In the past, it was separated by human hands, but the economical efficiency was lowered and the mortality rate was very high due to the forced force. Since the use of a high-pressure sprayer using seawater for easy peeling of abalone patch these days, a method of dissolving abalone patch by dissolving a drug in seawater has been used.

In order to peel abalone plaque from the shellta, the bottom, etc., the currently used abalone farm is antibiotic oxytetracycline, and some use natural herb. The reason for using oxytetracycline hydrochloride as a release agent for abalone or abalone patch in abalone farm is that the abalone patch temporarily withers the taste of the drug when spraying oxytetracycline-containing seawater into the high pressure sprayer. It is assumed that this is because the impact is easily separated from the sheller, the bottom, and the like.

Oxytetracycline hydrochloride, however, is an antibiotic and should not be used in animals donated for human consumption.There is a risk of residue in abalone, which may cause antibiotic resistance in humans who consume abalone. It is also known that about 10-15% of abalone plaques die after exfoliation using oxytetracycline hydrochloride. Despite these antibiotic resistance problems and high mortality, the use of antibiotics oxytetracycline for abalone plaque removal in abalone farms is the most economical and effective way to date and no alternative means.

Therefore, the problem to be solved by the present invention is to provide an abalone stripper composition, which is easy to peel abalone, preferably abalone patch, mortality after peeling is improved, and economical.

In order to solve the above problems, the present invention is an acid, such as citric acid, vitamin C (ascorbic acid), acetic acid, malic acid, succinic acid, fumaric acid, tartaric acid, salicylic acid, gluconic acid, lactic acid, preferably citric acid, vitamin C or a mixture thereof More preferably, it provides a composition for abalone peeling, containing citric acid and vitamin C together as an active ingredient.

The present invention is based on the surprising fact that the acid can not only increase the peeling effect compared to the materials used as a conventional peeling component, but also improve the mortality, can be used at a high dilution ratio is very economical.

In the use of the composition according to the present invention, it is preferable that the abalone is an abalone patch, but the composition of the present invention is not limited to only peeling the abalone patch, but may also be used for peeling the grown abalone. In addition, the present invention can be used in various kinds of abalone, such as veteran abalone, black abalone, seabolt abalone.

The composition according to the present invention may further contain various excipients which do not inhibit the object of the present invention in addition to the (organic) acid which is the active ingredient, and sugars are preferable as such excipients. As such sugars, glucose, lactose and the like can be used, of which glucose is more preferable.

Citric acid, vitamin C, and the like, which are active ingredients included in the abalone release agent composition according to the present invention, are about 0.5 to 10 g, preferably about 1 to 7 g, more preferably about 1.3, per 1 L of water (preferably seawater). To 5 g of the mixture may be used.

In addition, the abalone release agent composition according to the present invention may include a variety of additional components within the range that does not impair the object of the present invention, for example, the nutritional component of abalone patch, the nutritional component of diatoms that feed the abalone It may further include, but is not limited thereto.

The present invention is excellent in the peeling effect of abalone or abalone patch, significantly reduced mortality, can be used diluted to a high magnification provides an economical abalone release agent composition.
