Description

Method for manufacturing a functional sweet feed composition that promotes sex hormone secretion {METHOD FOR MANUFACTURING FEEDSTUFF COMPOSITION PROMOTING SECRETION OF SEX-HORMONE}

The present invention relates to a method for producing a sweet feed composition that has the effect of improving the stability of fat in grains such as flaxseed and has the effect of improving the absorption rate of lignans, omega-3, etc. in grains when consumed by animals.

Feed is food that provides nutrition to animals such as livestock or companion animals, maintains life, and is necessary for health maintenance or growth, and includes sweetened feed, compounded feed, and supplementary feed.

Sweet feed refers to raw feed that is made of vegetable, animal, or mineral substances and is used directly as feed or as a raw material for compound feed. At this time, good feed must have a high ability to supply nutrients to livestock, be harmless and non-toxic to livestock, have a high production volume and be easily available, the nutrients must be fresh and not easily deteriorated, and the digestibility of nutrients must be high.

Blended feed is a mixture or processing of sweet feed, auxiliary feed, etc. in an appropriate ratio, and can be manufactured by varying the ratio depending on the intended use. Meanwhile, supplementary feed is added to feed to prevent feed quality deterioration or increase feed utility, and includes essential minerals, vitamins, etc.

Flaxseed (linseed) is one of the world's best superfoods. It is a flat, long, oval-shaped seed grown for medicinal purposes and nutritional products. It is rich in fiber, phytoestrogen lignans, and alpha-linolenic acid, an essential omega-3 fatty acid, which is essential for human health. It is widely used not only for consumption but also as vegetable sweet feed for animals.

However, flax seeds have a high content of unsaturated fatty acids, so rancidity occurs relatively quickly. Rancid fat reduces the quality of feed and can be absorbed into the body and have a negative effect on animals, so it is necessary to allow absorption of the active ingredients of flax seeds. However, preventing rancidity of the fat contained in large quantities in flax seeds is essential for maintaining feed quality and animal health.

Republic of Korea Patent Publication No. 2023-0079739 is a method of manufacturing livestock feed that prevents fatty acid rancidity and reduces prussic acid in flax seeds through special processing, and includes a puffing extrusion process including a high temperature and high pressure puffing process, an antioxidant addition process, and a vacuum packaging process.

Hereinafter, each configuration of the present invention will be described in more detail so that those skilled in the art can easily implement it. However, this is only an example, and the scope of rights of the present invention is determined by the following contents. Not limited.

As used herein, “preferred” or “preferably” refers to an embodiment of the invention that has certain advantages under certain conditions. However, other embodiments may also be preferred under the same or different conditions. Additionally, the identification of one or more preferred embodiments does not mean that other embodiments are not useful, nor does it exclude other embodiments that are within the scope of the invention.

As used herein, the term “comprising” is used to list materials, compositions, devices, and methods useful in the present invention and is not limited to the listed examples.

In particular, in the present invention, the term "comprising" refers to various states, such as a state in which the component is included as is, a state in which the component is processed as a precursor, a state in which the component is satisfied after processing, etc. It is not limited to the examples listed.

Flaxseed is the seed of an annual herb native to Central Asia. Flaxseeds are squeezed and used as flaxseed oil, and are rich in lignans and omega-3. Among these, lignans act as phytoestrogens and have the effect of preventing diseases such as breast cancer and uterine cancer. However, lignans are poorly soluble substances that do not dissolve in water, so there is a problem in that they are not easily absorbed into the body.

Meanwhile, unsaturated fatty acids such as omega-3 have a higher rate of rancidity than saturated fatty acids, and flax seeds contain a large amount of unsaturated fatty acids, making them prone to rancidity.

In this way, although flaxseed contains a large amount of ingredients useful to animals, the amount absorbed into the body is not large compared to the content, and the raw material and processed product have the disadvantage of being prone to rancidity.

The present invention is intended to solve this problem, and its purpose is to improve the fat stability of flaxseed, prevent rancidity of unsaturated fatty acids, and process it into a sweet feed with improved preservability. Furthermore, the absorption of active ingredients into the animal's body is achieved. The purpose is to increase the body utilization rate of the active ingredient.

Specifically, the method for producing a sweet feed composition using flaxseed according to the present invention includes the steps of a) mixing flaxseed and oats to prepare a mixture; b) puffing the mixture; c) adding air at 10 to 15° C. to the puffed mixture for 10 to 60 minutes; d) spreading the mixture obtained in step c) thinly and drying it; e) pulverizing the mixture obtained in step d); and f) forming the powder of step e) into pellets; Includes.

In order to improve the fat stability of flaxseed containing unsaturated fatty acids and the absorption rate of lignans in animals, flaxseed that has undergone a certain pretreatment is mixed with oats and a process is performed to improve the structure of the mixture so that it can be absorbed into the digestive organs. By puffing to ensure smooth digestion and then manufacturing it through a predetermined process, it has the effect of improving the storage of sweetened feed and improving the absorption rate of lignans and omega-3 contained in flaxseed.

Below, each step is described in more detail.

Step a) is a step of measuring flax seeds and oats and mixing them in a predetermined ratio.

Oats play a role in stabilizing the unsaturated fatty acids contained in large quantities in flax seeds, and as will be described later, they absorb the unsaturated fatty acids eluted during the process of grinding the mixture, solving the problem of the unsaturated fatty acids easily becoming rancid in the eluted state.

Specifically, the flaxseed and oats include 80 to 90% by weight of flaxseed and 10 to 20% by weight of oats, based on the total weight of the mixture. More preferably, it may contain 83 to 87% by weight of flaxseed and 13 to 17% by weight of oats.

If the flaxseed content is excessive than the above weight, there are problems such as fat components eluted during the grinding process or the viscosity of the ground product increases, causing it to stick to the grinder or easily lose its shape even after being formed into pellets. If the content of flaxseed is small compared to the weight, the content of the active ingredients, especially lignans and omega-3, which are desired to be obtained by increasing the content of flaxseed as a single feed, decreases, which reduces the amount of flaxseed used in compound feed. In this case, there is a problem that its effectiveness is lower compared to the same weight and the same volume.

Meanwhile, the flaxseed can be used after going through a pretreatment process. Specifically, the flaxseed can be used by soaking it in 70% alcohol for 10 minutes, drying it, then soaking it in 95% alcohol for 5 minutes, washing it with water, and then drying it. This is a process to emulsify the skin on the surface of the flaxseed and remove toxins, so that more micropores are formed in the tissue of the flaxseed during the future puffing process, and to maximize the increase in volume after puffing.

Since cyanogenic glycosides in flaxseed hulls can cause toxicity, in order to remove them, they are first immersed in low concentration alcohol for 10 minutes to soften the surface tissue, and then immersed in higher concentration alcohol to dissolve toxic substances. , Afterwards, wash with water and use.

In addition, during this process, the tissue of the flaxseed outer shell becomes soft in low concentration alcohol, and in the step of immersion in high concentration alcohol, the flaxseed tissue after removing the toxicity is strengthened again. However, in this process, by immersing it in a low concentration of alcohol, not only the outer skin but also the internal tissue becomes soft and then hardened again, making the tissue hard with micropores formed inside.

Subsequently, through the process of washing with water, a small amount of water penetrates into the inside of the flaxseed, allowing the subsequent puffing process to be performed well.

Step b) is a puffing step and is performed using a puffing machine. Before being put into the actual puffing machine and puffed, it is maintained at a temperature of -10 to 1℃ for 10 to 30 minutes, then maintained at -30 to -20℃ for 10 to 30 minutes, and then puffed at a temperature of -20 to -10℃ for 10 to 30 minutes. The step of maintaining for 30 minutes is performed to form a physical crack in the inner tissue of the flax seed through the cooling-cryogenic cooling-low temperature cooling process while the moisture is contained inside the flax seed tissue. This serves to further improve the puffing rate during puffing. In particular, it uses the micropores formed deep inside the flaxseed and the water trapped within them to allow puffing to occur even inside the flaxseed, helping digestion of nutrients when feeding feed. This is to maximize absorption rate.

The puffing conditions are not particularly limited, but can be appropriately changed depending on the surrounding environment.

Step c) is a step of adding air at 10 to 15°C for 10 to 60 minutes to the puffed mixture, and is a process to induce natural cooling rather than rapid cooling. Air is first applied to slightly lower the temperature, and then in step d), it is spread thinly on a metal tray and dried. This process is to prevent the product from becoming soggy due to moisture during the natural cooling process.

Step c) may be performed by placing the vacuum chamber in a vacuum chamber for 1 to 3 hours before adding air and then adding air. This is to prevent the mixture puffed through the process of placing it in a vacuum chamber from slightly reducing in size as it cools immediately after puffing. The advantage of performing this process is that the puffing rate is improved and the digestibility of the sweet feed is improved. There is.

Step e) is a step of pulverizing the puffed mixture, and can be formed into a uniform powder by simultaneously pulverizing flaxseed and oats, or a mixed powder containing flaxseed and oats. The particle size at the time of grinding is about 50 to 100 mesh to prevent the structure from being too agglomerated when forming into pellets.

Step f) is a step of forming pellets, and can be formed at a level similar to commercially available single feed, and can be formed in various shapes and sizes as needed.

Hereinafter, the present invention will be described in more detail based on examples, but this is only an exemplary description for understanding the present invention, and the scope of the present invention is not limited or restricted to the following examples.

<Example 1>

The mixture was kept at a temperature of -5℃ for 30 minutes, then kept at -25℃ for 30 minutes, then kept at a temperature of -10℃ for 30 minutes and then immediately placed in a puffer, drying temperature of 40℃, moisture content. The mixture was puffed under conditions of 12% and a puffing temperature of 220°C. Air at 10 to 15°C is applied for 30 minutes, and then spread thinly on a stainless steel tray to dry.

This was then pulverized into a powder of 50 to 100 mesh, and then put into an extruder to form pellets to prepare sweet feed.

4. Evaluation of the effect of improving sexual function through improving lignan absorption rate

In order to confirm the effectiveness of the sexual function enhancement function, one set of male and female cattle were prepared for each experimental group. In the experiment, each group was first observed for 6 months, blood from cows in estrus was collected, and the concentration of sex hormones (estrogen) was measured.

Based on this, after feeding feed for 3 months, observe for 3 months, collect blood from cows in estrus, measure the concentration of sex hormones, compare this with the concentration of sex hormones before feeding feed, and calculate the measured value as follows. It is shown in the table.

Sex hormone concentration ratio (%) = 100* (average sex hormone concentration in blood after feeding)/(average sex hormone concentration in blood before feeding)

Sex hormone concentration ratio (%) Example 1 110 Example 2 119 Comparative Example 1 93 Comparative example 2 102 Comparative Example 3 98 Comparative Example 4 103

Referring to Tables 1 to 5, the sweet feed of Examples 1 and 2 showed excellent results compared to the comparative examples in meat mass and meat quality evaluation, and the concentration of sex hormones increased with feeding in Examples 1 and 2. You can check it.

In particular, these results are presumed to be due to the fact that the process before and after puffing allowed puffing to occur in the internal tissue of the flaxseed containing lignans, thereby improving the digestion and absorption rates of the lignans in the flaxseed.

Meanwhile, it was confirmed that the sweet feed of Examples 1 and 2 was excellent in the preservability evaluation. By mixing flax seeds and oats in a predetermined ratio and puffing them, the texture, color, and flavor were maintained at a somewhat high temperature by stabilizing the fatty acids. It can be confirmed that everything is maintained without deformation.

In the case of Example 2, even in comparison with Example 1, it can be confirmed that the absorption rate of nutrients is further improved by performing the process of putting it into a vacuum chamber after puffing.
