Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of feed, and particularly relates to a water product feeding attracting composition and a preparation method thereof. BACKGROUND

[0002] In the field of water product breeding, the performance of the feeding attracting composition directly affects the feeding efficiency, growth rate and breeding economic benefits of water product animals. There are two prominent problems in the water product feeding attracting compositions on the market: one is poor feeding attracting effect, most of the products only rely on single or a few traditional feeding attracting ingredients such as amino acids and nucleotides, which are difficult to match the olfactory and gustatory preferences of different water product animals in different growth stages, resulting in narrow feeding attracting range, weak attraction, low feeding enthusiasm of water product animals, and excessive residual feed and reduced feed utilization rate; the other is high dissolution rate in water. Due to the lack of reasonable formula raw material design and preparation technology, the composition is quickly dispersed and dissolved after being put into water, and a large amount of effective components are lost in a short time, which not only reduces the continuous action time of the feeding attracting components, but also may cause adverse effects on the water environment due to the local high concentration, and increases the breeding cost.

[0003] Therefore, it is a technical problem to be solved in the current water product breeding field to develop a water product feeding attracting composition which can significantly improve the feeding attracting effect and reduce the dissolution rate in water. SUMMARY

[0004] The present application belongs to the technical field of feed, and particularly relates to a water product feeding attracting composition and a preparation method thereof.

[0007] The grain powder, inorganic powder, river snail meat powder, vegetable oil, gluten powder, egg yolk oil and yeast nucleotide are mixed to form the water product feeding attracting composition.

[0008] The river snail meat powder is rich in protein, amino acids and unsaturated fatty acids and other components, and can release fishy substances in water to activate the olfactory capsule of fish.

[0009] The egg yolk oil contains lecithin, fat-soluble vitamins and fatty acids and other components, and releases fishy aroma similar to animal fat in the process of slow release in water, which has natural attraction to fish. In addition, the oiliness of the egg yolk oil can wrap the feed particles, reduce the powder feeling and improve the taste, especially in water product feed, which can enhance the stability of the feed in water and reduce the degree of collapse of the feed in water.

[0013] The puffed glutinous rice powder is light yellow in color, and the puffed glutinous rice powder has a honeycomb structure, slowly expands in water, and can produce a "cloud and mist" appearance to increase the suspension time and dispersion area.

[0014] The puffed pea powder is milky white in color, can provide high-quality plant protein and crude fiber, and slowly dissolves in water, which can prolong the time of visual stimulation.

[0015] The barley malt powder is rich in digestive enzyme substances such as amylase and invertase, which can enhance the absorption capacity of the intestinal tract to the nutrients in the feed, indirectly enhance the appetite by improving the absorption efficiency, and further promote the feeding.

[0016] Further, the grain powder comprises 22-28 parts by weight of puffed glutinous rice powder, 14-20 parts by weight of puffed pea powder, and 8-15 parts by weight of barley malt powder.

[0017] As a preferred technical scheme of the present application, the inorganic powder comprises tricalcium phosphate and titanium dioxide.

[0018] Tricalcium phosphate has a high refractive index and can reflect light to provide a certain brightening effect. In addition, tricalcium phosphate also has good anti-caking ability.

[0019] Titanium dioxide has the property of reflecting light and can provide high brightness to improve the visibility of the feed at a long distance in turbid water.

[0020] Further, the inorganic powder comprises 2-4 parts by weight of tricalcium phosphate and 1-1.5 parts by weight of titanium dioxide.

[0021] As a preferred technical scheme of the present application, the vegetable oil comprises perilla seed oil.

[0022] Perilla seed oil is rich in volatile oil, perilla aldehyde, limonene and other active ingredients, which can stimulate the taste sense of aquatic animals and enhance the feeding desire.

[0023] The second aspect of the present application provides a preparation method of an improved water product feeding composition, comprising the following steps:

[0024] (1) Stir and premix cereal powder, inorganic powder, river snail meat powder, gluten and yeast nucleotide to obtain mixture A, and mix plant oil and egg yolk oil uniformly at a controlled temperature to obtain mixture B;

[0025] (2) Sprinkle mixture B uniformly on mixture A while stirring, and continue to stir after the spraying is completed to obtain mixture C;

[0026] (3) Extrude and granulate mixture C, and dry to obtain the finished product.

[0027] As a preferred technical solution of the present application, the premixing time in step (1) is 3-5 min, and the temperature of the controlled temperature is 40-45℃.

[0028] As a preferred technical solution of the present application, the continued stirring time in step (2) is 5-10 min.

[0029] As a preferred technical solution of the present application, the extrusion speed of the extrusion granulation in step (3) is 60-65 r / min, and the granulation die plate is 0.25 mm; and the drying is to control the moisture content of mixture C to be 6-10%.

[0030] The third aspect of the present application provides a kind of to improve the application of aquatic food in the preparation of feed composition, the composition is added according to 1-2.5% of total mass of feed.

[0031] The beneficial effects of the present application are:

[0032] (1) The present application selects puffed glutinous rice powder, puffed pea powder, tricalcium phosphate and titanium dioxide as visual food attracting components, with white-yellow as the base tone that most fish can see and love to eat, supplemented by tricalcium phosphate that can provide brightening effect and titanium dioxide that can reflect light, so that fish can see feed at a long distance in relatively turbid water, thereby effectively stimulating the interest of fish in eating; In addition, titanium dioxide has the defects of large specific gravity and easy sinking, and the glutinous rice powder and pea powder added in the present application are both puffed, which can complement each other and form a floating and sparkling micro-dynamic visual stimulation effect in water, effectively accelerating the speed of fish locating feed;

[0033] At the same time, the present application also adds river snail meat powder, egg yolk oil, perilla seed oil, barley malt powder and yeast nucleotide, which synergistically promotes the sustained feeding of aquatic animals from different dimensions of stimulating olfaction, increasing palatability, stimulating taste and promoting intestinal absorption, so that the finished product obtained from the composition has excellent food attracting effect.

[0034] (2) The egg yolk oil selected by the present application has certain adhesion ability in addition to the effect of increasing palatability, but the adhesion ability of single egg yolk oil is difficult to stably adhere to all raw materials of the composition, therefore, the present application also adds gluten which has high viscoelasticity after water, so as to prevent water from rapidly penetrating into the inside of the bait composition. The egg yolk oil as a natural hydrophobic substance can fill the small pores of the gluten protein network and cover the surface of the gluten to form a continuous hydrophobic film, further reducing the penetration of water molecules, so that the finished composition prepared thereby can reduce the dissolution rate in water and has good water product special performance.

[0090] Test Example 1

[0091] The test example uses carp with good vitality, uniform size, and a weight of 30 ± 2 g. The juvenile fish are randomly divided into 11 square breeding pools with a side length of 2 m, with 50 fish per pool. The fish are deprived of food for 24 h before the test. During the experiment, the waste is discharged every day, and the water is replaced once a day. The dissolved oxygen is maintained above 6.0 mg / L. The water temperature is 23°C. The test period is 30 days. The feeding amount is 5% of the body weight, and the feed is fed twice a day (8:00 and 17:00) to the 11 breeding pools. The feed is prepared by adding the feed products prepared from the attractant compositions of Examples 1-3 and Comparative Examples 1-8 to the feed (feed composition: 35wt% soybean meal, 30wt% bran, 20wt% rapeseed meal, 12wt% cottonseed meal, 0.5wt% premix (premix from Guangdong Xindun Biological Technology Co., Ltd., product name: miscellaneous fish compound premix), and 0.5wt% calcium dihydrogen phosphate, 2wt% attractant composition), and the feed is fed to the fish. Among them, 60% of the feed amount is fed at 8:00, and 40% of the feed amount is fed at 17:00. After each feeding, the remaining feed is removed and dried to a constant weight after 3 h. The average daily feed intake per fish per group is calculated, and the total average feed intake per fish per group for the 30-day test period is calculated. The results are shown in Table 1.

[0092] Table 1

[0093]

[0094]

[0095] As can be seen from the comparison of the data of Comparative Examples 1-4 and Example 1-3 in Table 1, the puffed glutinous rice powder, puffed pea powder, tricalcium phosphate, and titanium dioxide selected in the present application as visual attractant components can effectively accelerate the speed of fish positioning the feed and increase the feed intake. As can be seen from the comparison of the data of Comparative Examples 5-8 and Example 1-3, the snail meat powder, egg yolk oil, perilla seed oil, and barley malt powder selected in the present application can effectively stimulate the olfactory sense, increase the palatability, stimulate the taste, and promote the absorption of the intestinal tract from different dimensions, thereby synergistically promoting the sustained feeding of aquatic animals. Therefore, the composition product prepared therefrom has excellent attractant effect.

[0096] Test Example 2

[0097] The composition prepared from Example 1-3 and Comparative Examples 9-10 without soaking is weighed, and then placed in a 105°C oven for 24 h to a constant weight to calculate the water content X. This test example has a total of 2 different experimental groups for each example or comparative example group, and each group includes three parallel experiments. The same M1 weight (5 g) of composition is weighed and soaked in seawater with a water temperature of 24°C. After 1 h and 10 h of soaking, respectively, it is taken out and placed in a 105°C oven for 24 h to a constant weight M2. The dispersibility is calculated according to the following formula:

[0098] S(%) = {[M1 x (1-X) - M2] / [M1 x (1-X)]} x 100%;

[0099] In the formula:

[0100] S is the dissolution rate, %;

[0101] X is the moisture content, %;

[0102] M1 is the initial mass of the composition, g;

[0103] M2 is the mass after soaking for a specific time and drying for 24 h to constant weight, g;

[0104] The results are shown in Table 2.

[0105] Table 2

[0106]

[0107] As can be seen from Table 2, the compound product prepared in the application has a smaller dissolution rate in water. This is because the egg yolk oil and the wheat gluten powder are added to prevent water from rapidly penetrating into the inside of the bait composition, the egg yolk oil fills the small pores of the wheat gluten protein network and covers the surface of the wheat gluten powder to form a continuous hydrophobic film, further reducing the penetration of water molecules, so the composition product prepared therefrom can reduce the dissolution rate in water and has good water product special performance.
