Problems solved by technology

In the case of settled particles, although gluten can also be excluded, suspended particles cannot be prepared without gluten (wheat flour)
[0014] Moreover, fish do not have the function of partially decomposing the feed by secreting enzymes such as amylase while chewing the feed in the oral cavity. When the feed is swallowed and sent to the stomach, the starch that can be decomposed and grains that are vegetable proteins are not secreted in the stomach. Protein's own enzyme, or a very small amount of secretion, so it cannot decompose β-starch (decompose α-1, 4 glycosidic bonds) in the gastric juice of fish
As a result, fishmeal, which is the main feed source, adhered to starch, is not easy to be decomposed by pepsin in the stomach, and the digestion efficiency in the intestine is also reduced, so that the feed that is taken into the bait cannot be fully utilized, so the feed coefficient increases and the growth rate increases. passivation problem

Embodiment approach

[0028] Such the present invention will be described in more detail as follows.

[0029] The present invention relates to a method for preparing pelleted feed for fish farming which is coated with enzymes after being molded, so that it slowly disperses after a certain period of time in water, disintegrates quickly in the stomach of fish, and has excellent digestion efficiency.

[0030] The core of the present invention is the pellet feed for fish farming in which enzyme is coated on the molded pellet feed and its preparation method.

[0031] More specifically, after the pellet feed is formed and coated with enzymes, these enzymes are adsorbed to the surface of the pellets, and when the fish feed, the enzymes adsorbed on the surface are activated in the gastric juice and the disintegration is accelerated, and the digestion efficiency is greatly improved.

[0032] The enzyme is alpha-amylase, maltogenic amylase, beta-amylase, cellulase, beta-glucanase, glucoamylase, hemicellulase...

Embodiment 1

[0047] [Example 1: Enzyme liquid coating once after puffed granules are formed]

[0048] (A) Extruded pellet feed composition

[0049] Fish meal (Chile super premium) 70.0% by weight

[0050] Flour (wheat flour) 4.0% by weight

[0051] Alpha starch 7.0% by weight

[0052] Peeled bean cake 2.0% by weight

[0053] Squid Liver Fish Meal 2.0% by weight

[0054] Corn Extracted Gluten 3.0% by weight

[0055] Salmon Oil 2.0% by weight

[0056] Multivitamins and multiminerals 0.5% by weight

[0057] Water vapor 9.5% by weight

[0058] (B) Mixing and crushing

[0059] Put the composition of (A) into a mixer and mix uniformly for 20 minutes, then move to a pulverizer and run for 30 minutes to pulverize until it reaches 80 mesh.

[0060] (C) Extruder and cooling

[0061] The pulverized composition of item (B) is put into an expander, and steam is sent to expand it to form particles with a diameter of 9-10 mm, and the formed particles are cooled by an air cooler.

[0062] (D) E...

Embodiment 2

[0085] [Example 2: 1, 2 times of coating after puffed granules are formed]

[0086] (A) The composition and molding method of the expanded granules are the same as in Example 1.

[0087] (B) Preparation of enzyme solution

[0088] 0.4 g of α-amylase, 0.5 g of acid protease, and 0.1 g of lipase were added to 2500 g of molded pellet feed, and water was added to 100 g.

[0089] (C) Coating method

[0090] With respect to 100 parts by weight of the extruded pellet feed, fish oil (salmon oil) is sprayed on the surface of the pellets once to increase the amount to 2 to 3 parts by weight, and then the enzyme solution is coated twice to compare 2-3 parts by weight based on 100 parts by weight of extruded pellet feed.

[0091] It is thus proved that once the oil is coated once, the oil will form a coating on the surface of the particle, and α-amylase, protease, lipase, etc. will not penetrate into the inside of the particle, and thus slowly disperse in water (sea water). The effect...

Abstract

The present invention relates to a pellet feed for fish farming having excellent dissolution and digestion efficiency, and a method for preparing the same, and more specifically to a pellet feed for fish farming wherein the pellet feed is molded then coated with an enzyme, whereby the pellet feed disperses slowly in water over a certain time period, but quickly dissolves in a fish's stomach and has excellent digestion efficiency.

Description

【Technical field】 [0001] The present invention relates to a pellet feed for fish farming with excellent disintegration and digestion efficiency and a preparation method thereof. 【Background technique】 [0002] There are two types of feed for fish farming. One is a powder feed prepared by adding mixed flour, fish meal, bean cake, etc. to fish (mackerel, mackerel, sardine, anchovy, etc.) and grinding it into pellets. Afterwards, the raw feed (Moisture Pellet, MP) that is baited after being frozen at 20°C in order not to break the shape of the shape, and the other is the puffed granules that are mixed with fish meal, flour, starch, bean cake, gluten, etc. and formed in the puffer (EP, SEP, DP), currently the most used raw feed (MP) is to feed the frozen pellets to the fish and throw them into the water tank, and 10~15% of them will disperse before the fish eat and flow into the sea, so It has become the main culprit of sea pollution, so the government authorities mobilized var...
