Description

Technical Field

[0001] The present disclosure relates to the technical field of pet food, and particularly to a pet nutritional supplement granule and a preparation method thereof. Background Art

[0002] Antarctic krill oil is a natural oil extracted from Antarctic krill and is rich in various nutritional components beneficial to pet health. The ω-3 fatty acids it contains, especially EPA and DHA, have strong anti-inflammatory properties, can effectively reduce joint inflammation, relieve pain and swelling caused by diseases such as arthritis, and its lubricating effect can effectively prevent the occurrence of joint diseases for pets that often exercise or are older. However, existing Antarctic krill oil supplements for pets usually exist in the forms of soft capsules, capsules, dripping pills, etc., with poor palatability for pets, and there are also problems such as low utilization rate of Antarctic krill oil, and allergic reactions such as soft stools, skin itching, erythema, and ear infections in some pets after consumption.

[0003] Moreover, the above-mentioned Antarctic krill oil products have a single nutritional component. If other types of nutrients, such as calcium, iron, zinc and other nutrient elements, need to be supplemented, additional feeding is required.

[0004] Therefore, how to provide a product with good palatability, which can simultaneously supplement Antarctic krill oil and other nutrient elements, and improve the utilization rate of Antarctic krill oil, pet palatability, and relieve allergic reactions has become an urgent problem to be solved currently. Summary of the Invention

[0005] To solve the above technical problems, the present disclosure provides a pet nutritional supplement granule and a preparation method thereof.

[0006] In a first aspect, the present disclosure provides a pet nutritional supplement granule, including a bursting bead core material and a nutritional layer coated on the surface of the bursting bead core material;

[0007] The bursting bead core material includes a wall material and a core liquid wrapped inside the wall material;

[0008] By weight, the core liquid includes 75 - 85 parts of Antarctic krill oil, 15 - 25 parts of DHA algal oil, and 5 - 10 parts of pumpkin seed oil;

[0009] The components of the nutritional layer include taste-masking pellets, and the taste-masking pellets include a pellet core and a coating layer coated on the surface of the pellet core;

[0010] The pellet core contains vitamins;

[0011] The components of the coating layer include first animal-source meat, amino acids, table salt, sodium alginate, polyethylene glycol, hydroxypropyl methylcellulose, and zein.

[0012] Among them, the weight parts of Antarctic krill oil are such as 75 parts, 77 parts, 80 parts, 82 parts or 85 parts, etc.; the weight parts of DHA algal oil are such as 15 parts, 17 parts, 20 parts, 23 parts or 25 parts, etc.; the weight parts of pumpkin seed oil are such as 5 parts, 6 parts, 7 parts, 8 parts, 9 parts or 10 parts, etc., but are not limited to the listed values, and other unlisted values within the above range are equally applicable.

[0013] On the one hand, in view of the problems of low utilization rate of Antarctic krill oil and causing allergies in some pets in the prior art, by adding DHA algal oil and pumpkin seed oil, the two act synergistically, not only improving the utilization rate of Antarctic krill oil, but also effectively alleviating diarrhea, skin itching, erythema and ear infections caused by allergies; at the same time, through the encapsulation of the nutrient layer, the resistance of pets to Antarctic krill oil is reduced; on the other hand, the present disclosure also solves the resistance psychology of pets when eating vitamin supplements by making the vitamin raw materials with too strong taste into taste-masked pellets and adding them to the nutrient layer, and also improves the palatability without additionally increasing the taste layer by adjusting the formula of the taste-masked pellets, and at the same time realizes the sustained-release function and relieves the gastrointestinal pressure of pets.

[0129] Product performance test

[0130] Determine the utilization rate of Antarctic krill oil in the pet nutritional supplement granules obtained in Examples 1-3 and Comparative Examples 1-4.

[0131] Utilization rate of Antarctic krill oil % = total discharge mass of bursting bead core material / (total mass of core liquid materials + total mass of edible glue materials) × 100%, where the edible glue refers to gelatin, and the amounts of glycerol and sorbitol are not counted.

[0132] The results of the utilization rate of Antarctic krill oil in the pet nutritional supplement granules obtained in Examples 1-3 and Comparative Examples 1-4 are shown in Table 1.

[0133] Table 1

[0134]

[0135] Conclusion:

[0136] From the measurement results, it can be seen that adding DHA algal oil and pumpkin seed oil to the pet nutritional supplement granule product of the present application in the Antarctic krill oil bursting beads ensures the structural stability of the product, thereby effectively improving the utilization rate of Antarctic krill oil, increasing it from 49% to over 73%.

[0137] There is only Antarctic krill oil in the core liquid of the bursting bead core material of Comparative Example 1, resulting in a low utilization rate.

[0138] In Comparative Examples 2 and 3, only one of DHA algal oil or pumpkin seed oil was added, and the two could not play a synergistic role, resulting in limited improvement in the utilization rate of Antarctic krill oil.

[0139] In Comparative Example 4, the addition amount of pumpkin seed oil was too much, which instead reduced the utilization rate of Antarctic krill oil and increased the risk of pet allergy.
