Description

Technical Field

[0001] The invention belongs to the field of food technology, and specifically relates to a popping bead and a preparation method thereof, and in particular to a WBN natural fish oil preservation technology for pets. Background Art

[0002] We all know that cats like to eat fish, and most people also think that eating fish is good for cats. However, from a scientific point of view, it is safer and healthier for cats to eat fish oil, because fish itself has many bones, which can easily cause cats to get stuck in the throat if they are not careful. However, fish oil is much more convenient and will not put cats in such a dangerous situation. Moreover, fish oil has the same nutritional value as fish, because the main source of fish oil is fish fat. Moreover, the most important function of giving cats fish oil is to provide the necessary nutrients for the cat's skin, so that the cat's skin can be healthier. If the cat's skin is healthy, the cat's hair will be healthier, thereby reducing the occurrence of hair loss in cats. In addition, fish oil is not only rich in vitamins, which can promote calcium absorption, but also rich in Omega-3 and other fatty acids, which can lubricate joints and relieve pain. The DHA in fish oil can also protect the pet's eyes, heart and other organs.

[0003] Currently, fish oil products sold on the market are mainly tube-packed, bagged, bottled and compressed soft capsules with seams. Tube-packed and bottled fish oils mainly have oxidation problems, which are not conducive to the storage of fish oil products; compressed soft capsules with seams are larger and have thicker capsule shells, and need to be broken with external force to take out the fish oil for feeding. Not only is the operation cumbersome, but it is also easy to get the fish oil on the hands, making it inconvenient to feed. Summary of the invention

[0029] In order to enable those skilled in the art to clearly understand the above implementation details and operations of the present invention, the implementation of the present invention is illustrated by examples below.

[0030] Examples 1-3

[0031] The following Table 1 is the formula of the fish oil burst beads (seamless soft capsules) of each embodiment, and Table 2 is the performance test results of the fish oil burst beads (seamless soft capsules) prepared by each formula.

[0032] As shown in the results of Table 2, the fish oil bursting beads prepared in Examples 1-3 are easy to form, with a yield rate of more than 99%, and the bursting beads are soft and elastic with good thermal stability. The raw material for preparing the bursting bead wall material of Comparative Example 1 is only propylene glycol, and the fish oil cannot be wrapped by the bursting beads and cannot be formed, which directly leads to the failure of the preparation of fish oil bursting beads. The raw materials for preparing the bursting bead wall material of Comparative Example 5 do not contain propylene glycol, which results in the prepared bursting beads being hard, not soft, and inelastic. The amount of propylene glycol used in Comparative Example 6 is 40 parts, and there is no film-forming substance in the preparation process, which makes the bursting beads difficult to form; the propylene glycol in Comparative Example 12 is replaced by propylene glycol. Considering the dosage limit of propylene glycol food additives and safety considerations, the use of this raw material in the preparation process of the bursting beads is not considered. Combined with the results of Comparative Examples 1, 5, 6, and 12, it is shown that propylene glycol and its dosage have an important influence on the molding effect of fish oil bursting beads and the hardness of the bursting beads. The amount of collagen used in Comparative Example 2 is greater than 25 parts, the viscosity of the collagen glue is relatively high, the bubbles in the colloid are not easy to remove, and the dripper pipeline is easily blocked, resulting in the failure of the preparation process of the bursting beads. Comparative Example 10 replaces the collagen with carrageenan, resulting in a high viscosity of the glue and no formation, which directly leads to the failure of the preparation of fish oil bursting beads. Combined with the results of Examples 1-3 and Comparative Examples 1-2, it is shown that collagen and its dosage have an important influence on the formation and performance of fish oil bursting beads. The raw materials for the preparation of the bursting bead wall material in Comparative Example 3 do not contain calcium carbonate, and the bursting beads are not easy to form during the preparation process. In the raw materials for preparing the popping bead wall material of Comparative Example 4, the weight ratio of collagen and calcium carbonate is 22: 0.01. Combined with the results of Example 1 and Comparative Example 3, it is shown that the relative amount of collagen and calcium carbonate affects the molding of the popping bead. When the weight of collagen is 10 parts, the weight of calcium carbonate is less than 0.0045 parts, and when the weight of collagen is 15 parts, the weight of calcium carbonate is less than 0.0068 parts. Within this range, the molding effect of the popping bead can be guaranteed. Comparative Example 11 replaces calcium carbonate with calcium lactate, and the popping bead is not easy to form during the preparation process, which shows that calcium carbonate itself and its weight ratio with collagen also affect the molding effect of the popping bead. The amount of fish oil in Comparative Example 7 is 50 parts, the amount of fish oil in Comparative Example 8 is 140 parts, and the fish oil in Comparative Example 9 replaces fish oil with krill oil. These comparative examples all show that they are slightly difficult to form during the preparation of the popping bead, but the degree is relatively light.

[0033]

[0034] Note: RO water stands for water filtered through a reverse osmosis membrane Example 4

[0035] The fish oil burst beads (seamless soft capsules) prepared in Example 1 above were subjected to a comparative oxidation test at 37°C with commercially available fish oil products: The fish oil beads and various commercially available fish oil products were modeled for usage scenarios: after opening, they were placed in a constant temperature and humidity chamber (temperature 37°C, humidity 75%RH) for 3-5h / day, used once, 2-3 times / day, and physical and chemical tests were performed for 30 days. Among them, the fish oil Kress qualitative test references 1 (Xie Shouhua. Physical methods for determining oil oxidation [J]. Sichuan Cereals and Oils Science and Technology, 1999, 2: 51-53.), and reference 2 (Liu Yaomin, Mao Yanzhen, Song Jun, Zhang Rui, Zhou Xiumei, Zhang Fengping. Research on the evaluation system of freshness of feed oils [J]. Feed Industry, 2012, 33 (7): 61-64.). The acid value of fish oil is determined in accordance with "GB / T 5530-2005 Determination of acid value and acidity of animal and vegetable oils and fats", the peroxide value of fish oil is determined in accordance with "GB / T 5538-2005 Determination of peroxide value of animal and vegetable oils and fats", and the malondialdehyde value of fish oil is determined in accordance with "GB / T 5009.181-2003 Determination of malondialdehyde in lard".

[0036] As shown in Table 3, the above-mentioned fish oil bursting beads (seamless soft capsules) have better antioxidant stability than other fish oil products, and can effectively slow down the rancidity of oil and maintain the freshness of oil, which has positive significance for the development of products that need to mask taste and are easy to oxidize, and also fills the gap in the application of commercially available fish oil products in this field. At the same time, this also shows that the fish oil bursting beads (seamless soft capsules) and the preparation method thereof provided in this embodiment can also be used as a natural fish oil preservation method, which is represented by: WBN natural fish oil preservation method, wherein "W" in "WBN" represents Water-soluble capsule, i.e., water-soluble capsule; "B" represents Blister packaging, i.e., blister packaging; and "N" represents nitrogen filling, i.e., nitrogen filling.

[0037]

[0038] Example 5 This embodiment refers to Figure 2 The process flow shown in the figure is to prepare a fish oil bursting bead (seamless soft capsule) companion freeze-dried. Fresh meat or frozen meat is homogenized into meat paste or meat puree, with or without auxiliary materials, stirred evenly and then put into a mold, the semi-finished product after being put into the mold is put into a -40℃ quick freezer for quick freezing and forming, and finally the quick-frozen semi-finished product is vacuum freeze-dried, and the freeze-dried finished product is taken out for inspection, bagging, irradiation, inspection, and storage.

[0039] In order to verify the palatability effect of freeze-dried fish oil beads (seamless soft capsules), 20 healthy adult pet cats (different breeds, basically the same weight) were selected according to the common methods in the field to conduct palatability test experiments. The freeze-dried fish oil beads (seamless soft capsules) were placed in a food tray and placed in an independent test area for a single bowl test. The experimental dogs were allowed to eat independently, and the number of test dogs that ate freeze-dried fish oil beads (seamless soft capsules) was observed and recorded, as shown in Table 4.

[0040] Through the palatability test, it was found that the pet fish oil bursting beads (seamless soft capsules) companion freeze-dried in this embodiment had a preference rate of 90%, which has good palatability.

[0041]

[0042] In summary, the embodiments of the present invention are based on the different feeding methods and scene demands of dogs and cats, respect the feeding nature of dogs and cats, and develop a combination of gelatin, glycerol and calcium carbonate to complement each other's advantages, and a ratio of safe and non-toxic, fish oil oxidation-free, and convenient feeding. A kind of bursting bead (seamless soft capsule) product for dogs and cats. Its advantages include: ① The collagen with high gel strength has its own freezing strength, and it can gel and solidify at a temperature below 37°C; ② Glycerol can quickly absorb water in water to accelerate the expansion and dissolution of the bursting beads; ③ Collagen is a protein that can be quickly hydrolyzed under the action of oral proteases; ④ The synergistic effect of collagen, calcium carbonate and glycerol is used to prepare a high-performance fish oil bursting bead (seamless soft capsule); ⑤ The soft capsule embedding form can not only mask the fishy smell of fish oil, but also solve the problem that fish oil is easily oxidized; ⑥ The bursting beads are matched with freeze-dried companions to facilitate dogs and cats to eat independently. The advantages of each component complement each other and are mixed into safe, non-toxic, fast-dissolving and soft fish oil beads (seamless soft capsules). At the same time, in order to meet the independent eating nature of dogs and cats, it is chosen to be used in combination with freeze-dried companion.
