Description

{FEED COMPOSITION USING INSECTS AND METHOD FOR MANUFACTURING FEED USING THE SAME}

The present invention relates to a feed composition using insects and a method for producing the feed thereof, and more specifically, to a feed composition using insects containing lauric acid and a method for producing the feed thereof.

Recently, as the number of households raising pets increases, the pet industry is growing. In particular, as the aging population and the increase in single-person households overlap, the size of the pet market is expected to expand even further.

In the rapidly growing pet industry, the field in which technology is being developed most actively is 'feed'.

In particular, research on feed using insects has been active recently, and technology development is being actively carried out focusing on grasshoppers, crickets, and mealworms.

Insect feed is generally manufactured by crushing insects into powder, mixing with feed ingredients, and molding. The process of powdering insects is generally performed in the steps of washing, drying, and crushing.

However, problems due to viscosity occur during the grinding stage after drying. For example, if the viscosity is too high, it can cause problems such as breaking the grinder or clogging the grinder.

To solve the above-mentioned problem, fat is removed using an oiler after drying to lower the viscosity, and then crushing is performed.

Meanwhile, heating and compression are repeated during the milking process, and at this time, the milking machine is heated to a temperature of 40 to 50℃.

However, as heating and compression are repeated, there is a problem of loss of effective nutrients in the insect raw material, and in particular, there is a problem of loss of essential fatty acids and deterioration of taste and flavor.

Therefore, there is a need for technological development for a method of manufacturing feed using insects that can minimize the loss of effective nutritional components of insect raw materials and maintain their taste and flavor.

Meanwhile, the background technology described above is technical information that the inventor possessed for deriving the present invention or acquired during the process of deriving the present invention, and cannot necessarily be considered as publicly known technology disclosed to the general public prior to the application of the present invention.

FIG. 1 is a flow chart of a method for manufacturing feed using a feed composition using insects according to one embodiment of the present invention.

Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily practice the present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. In addition, in order to clearly describe the present invention in the drawings, parts that are not related to the description are omitted, and similar parts are assigned similar drawing reference numerals throughout the specification.

Throughout the specification, when a part is said to be “connected” to another part, this includes not only the case where it is “directly connected” but also the case where it is “indirectly connected” with another member or element in between. Also, when a part is said to “include” a certain component, this does not mean that it excludes other components, but rather that it can include other components, unless otherwise specifically stated.

The present invention will be described in detail with reference to the attached drawings below.

According to one embodiment of the present invention, a feed composition using insects comprises larvae and feed raw materials containing lauric acid. The larvae containing lauric acid are immature insects before metamorphosis into adults, and may include at least one of black-faced beetles, crickets, brown mealybugs, white-spotted flower chafers, centipedes, silkworm pupae, grasshoppers, maggots, and long-legged worms (mosquito larvae).

The black-tailed hawk moth is an insect belonging to the black-tailed hawk moth family in the order Diptera. It contains crude protein, crude fat, ash, calcium, and phosphorus, and is rich in essential amino acids such as arginine, methionine, and lysine. It also contains useful nutrients such as lauric acid, a saturated medium-chain fatty acid, and oleic acid and linoleic acid, which are unsaturated fatty acids.

Crickets are insects of the Cricket family in the Orthoptera order, and are rich in protein, fat, minerals, and vitamins, and contain lauric acid, palmitic acid, oleic acid, and linoleic acid.

The brown beetle is an insect belonging to the beetle family of the arthropod insect order Coleoptera, and contains a lot of protein as well as lauric acid, palmitic acid, and oleic acid.

The white-spotted flower chafer belongs to the Coleoptera order, Scarabaeidae family, and Floridinae subfamily. It has a high protein content, and among the unsaturated fatty acids, oleic acid accounts for more than 60% of the total fatty acids, and it also contains lauric acid, linoleic acid, and arachidonic acid.

All of the above-mentioned larvae contain lauric acid, which is a saturated fatty acid that can provide effective nutrition when fed to companion animals.

According to one embodiment of the present invention, feed raw materials include animal raw materials or plant raw materials.

Animal raw materials are the animal itself, an extract of the animal, or a component refined from the extract.

The animal source may include at least one of, for example, chicken, beef, duck, lamb, pork, horse, turkey, salmon, tuna, crocodile, rabbit, bream, pollock, and shrimp.

Plant-based raw materials are the plant itself, an extract of the plant, or an ingredient purified from such an extract.

The plant-based raw material may include at least one of, for example, rice, potatoes, sweet potatoes, tapioca, beans, coffee beans, chickpeas, and wheat flour.

The larvae and feed raw materials containing the above-described lauric acid are suitable for feed formation and can be included in an appropriate mixing ratio so as to have abundant effective nutrients.

For example, the larvae containing lauric acid may be included in an amount of 0.1 to 40 wt% based on the total weight of the feed composition using insects.

If the larvae containing lauric acid are included in less than 0.1 wt%, there is a disadvantage in that it is difficult for animals to digest and absorb quickly. In addition, if the larvae containing lauric acid are included in more than 40 wt%, there is a disadvantage in that palatability is reduced and animals avoid ingesting them.

Additionally, the feed raw material may be included at 50 wt% based on the total weight of the feed composition using insects.

For example, animal raw materials may be included in an amount of 0.1 to 50 wt% based on the total weight of the feed composition using insects.

For example, the plant-based raw material may be included in an amount of 0.1 to 50 wt% based on the total weight of the feed composition using insects.

When the feed ingredients are included in the weight ratio of the above-mentioned range, the taste of feed using insects is improved and there is an effect of preventing obesity. If the feed ingredients are included in less than 0.1 wt%, there is a disadvantage of lowering palatability. In addition, if the feed ingredients are included in excess of 50 wt%, there is a disadvantage of lowering the digestion and absorption rate.

As described above, the feed composition using insects according to one embodiment of the present invention includes larvae containing lauric acid. Lauric acid has the advantage of excellent antibacterial action, and can provide the advantage of easy feeding to companion animals by increasing the taste and flavor of the feed.

In particular, a feed composition using insects according to one embodiment of the present invention has excellent nutritional components compared to existing insect-based pet feeds by minimizing the loss of lauric acid, and has the characteristics of excellent taste and flavor.

Hereinafter, a method for manufacturing pet food using a feed composition using insects according to one embodiment of the present invention will be described with reference to FIG. 1.

FIG. 1 is a flow chart of a method for manufacturing feed using a feed composition using insects according to one embodiment of the present invention.

Referring to FIG. 1, a method for manufacturing feed using a feed composition using insects according to one embodiment of the present invention may be configured to include a cooling (S110) step of cooling larvae containing lauric acid, a grinding (S120) step of grinding the cooled larvae containing lauric acid without going through a milking process, a mixing (S130) step of mixing the ground larvae containing lauric acid and feed raw materials containing animal or plant raw materials, a molding (S140) step of molding the mixed mixture into a product, and a sterilization (S150) step of sterilizing the molded mixture.

The cooling (S110) step is a step of cooling the larvae containing lauric acid, and can be performed at a temperature range of -30 to 30°C.

If larvae containing lauric acid are cooled to a temperature below -30℃, they can easily deteriorate. On the other hand, if larvae containing lauric acid are cooled to a temperature above 30℃, fat may become rancid and sensory properties may deteriorate.

The crushing (S120) step is a step of crushing larvae containing cooled lauric acid to have an average particle size of 8 mm or less.

Preferably, it may be a step of grinding larvae containing lauric acid into a powder having an average particle size of 30 μm to 3 mm or less.

Grinding can be done using a wet grinder, a high-speed mixer with blades, etc.

The mixing (S130) step is a step of mixing raw materials with larva powder containing lauric acid.

The mixing step can be performed in a manner that the larvae powder containing lauric acid is mixed in an amount of 0.1 to 40 wt%, the animal raw material is mixed in an amount of 0.1 to 50 wt%, and the plant raw material is mixed in an amount of 0.1 to 50 wt% based on the total mixing ratio.

Mixing can be accomplished using a rotary kneading device having kneading blades to mix the mixed ingredients.

The molding (S140) step is the step of molding the mixed compound.

The forming (S140) step can be performed using a pelletizer.

The sterilization (S150) step is a step for removing harmful microorganisms within the molded mixture. The sterilization step may be a step for heat-treating the molded mixture.

Specifically, the sterilization step can be performed by steaming the molded compound using a steamer at a temperature range of 85 to 100°C.

If the molded mixture is heat-treated at a temperature below 85℃, the sterilization effect may not be achieved. If it is heat-treated at a temperature above 100℃, the sterilization effect is improved, but the effect gradually decreases, which may be disadvantageous in terms of cost.

In another example, the sterilization step can be performed by baking the molded compound using an oven at a temperature in the range of 130 to 180° C.

If the molded mixture is heat-treated at a temperature below 130℃, the sterilization effect may not be achieved. If it is cooled at a temperature above 180℃, the texture may not be good when consumed.

In another example, the sterilization step can be performed by frying the formed compound using a frying pan at a temperature in the range of 90 to 130° C.

If the molded mixture is heat-treated at a temperature below 90℃, the sterilization effect may not be achieved. If it is heat-treated at a temperature above 130℃, the texture may not be good when consumed.

As described above, the method for manufacturing feed using insects according to one embodiment of the present invention is characterized by not performing a separate milking process, but only cooling and crushing the larvae containing lauric acid to process them. Accordingly, the problem of lauric acid being lost due to heat and pressure generated during the milking process can be minimized.

In particular, by cooling and then crushing the larvae containing lauric acid, the problem of the pulverizer becoming clogged or damaged due to viscosity during the crushing process of the larvae containing lauric acid can be minimized, and the larvae can be effectively pulverized.

A method for manufacturing feed using insects according to one embodiment of the present invention can provide the antibacterial effect of lauric acid to companion animals by minimizing the loss of lauric acid, and can also improve the taste and flavor of the feed.

Hereinafter, in order to explain that pet food manufactured using a method for manufacturing feed using insects according to one embodiment of the present invention has the effect of reducing the loss of lauric acid, the following experimental examples will be described.

<Manufacturing Example 1 - Manufacturing of feed composition using insects>

First, a feed composition using insects was prepared using larvae of Dongae, etc. Specifically, as shown in [Table 1] below, a feed composition (exemplary composition) was prepared using larvae of Dongae, etc. according to the manufacturing method of Manufacturing Example 1, and a feed composition (comparative composition) was prepared using larvae of Dongae, etc. according to the manufacturing method of Comparative Example 1.

Manufacturing example 1 Comparative Example 1 start start ↓ ↓ Incoming and outgoing storage Incoming and outgoing storage ↓ ↓ cooling dry ↓ ↓ Milking ↓ smash smash ↓ ↓ complete complete

As can be seen from the above [Table 1], in Manufacturing Example 1, the “drying” and “milking” steps were omitted compared to Comparative Example 1, and the larvae of the same species were pulverized through “cooling” and then “pulverization.”

Specifically, in Manufacturing Example 1, the larvae of Dong-ae-deung were cooled to 5°C using a refrigerator. The cooled larvae of Dong-ae-deung were ground using a wet grinder at 750 rpm for 30 minutes.

In Comparative Example 1, the larvae of the black-tailed hawk were washed with water and then naturally dried. The dried black-tailed hawk larvae were placed in a hopper and milked at 45°C using a press-type milking machine. The milked black-tailed hawk larvae were ground using a wet grinder at 750 rpm for 30 minutes.

<Experimental Example 1 - Comparison of general nutritional components of feed compositions using insects>

The general nutritional components of the exemplary composition and comparative composition manufactured according to Manufacturing Example 1 and Comparative Example 1 of the above [Table 1] were analyzed.

Specifically, moisture (AOAC 930.15), crude protein (AOAC 976.05), crude fat (AOAC 954.02), and crude ash (AOAC 942.05) in the composition were each analyzed, and the analysis was performed according to the process analysis method of the Association of Official Analytical Chemists (AOAC).

The analysis results are as shown in [Table 2] below.

Implementation Composition Comparative Composition moisture 71.64 % 3.6 % Crude protein 13.18 % 44.1 % Joe's fat 9.60 % 10.3 % Views 3.52 % 14.3 %

Referring to the above [Table 2], the contents of crude fat in the exemplary composition and the comparative composition were 9.60 and 10.3%, respectively, and the contents of crude fat in the exemplary composition and the comparative composition were similar within the margin of error.

<Experimental Example 2 - Comparison of fat components in feed compositions using insects>

The general fat components of the exemplary compositions and comparative compositions manufactured according to Manufacturing Example 1 and Comparative Example 1 of the above [Table 1] were analyzed.

Specifically, the general fat components in the composition were analyzed according to the process analysis method of AOAC 969.33.

The analysis results are as shown in [Table 3] below.

Implementation Composition Comparative Composition Lauric acid 41.76 % 38.12 % Linoleic acid 12.83 % 7.36 % total 54.59 % 45.48 %

Referring to the above [Table 3], it can be seen that the lauric acid content of the exemplary composition increased by 3% or more compared to the lauric acid content of the comparative composition.

As can be seen from the results in the above [Table 3], the lauric acid content of the exemplary composition manufactured according to Manufacturing Example 1 is higher than that of the comparative composition manufactured according to Comparative Example 1. This is thought to be because, in the case of Manufacturing Example 1, no milking process is involved.

Meanwhile, the contents of major fatty acids of the exemplary composition manufactured according to Manufacturing Example 1 and the comparative composition manufactured according to Comparative Example 1 were quantitatively analyzed.

Specifically, the content of major fatty acids was calculated as the product of the content of general nutrients and fat components.

The results are shown in [Table 4] below.

Implementation Composition Comparative Composition Lauric acid 4.00 % 3.90 % Linoleic acid 1.23 % 0.76 % total 5.23 % 4.66 %

Referring to the above [Table 4], the contents of lauric acid in the exemplary composition and the comparative composition were 4.00 and 3.90%, respectively, and the contents of lauric acid in the exemplary composition and the comparative composition were similar within the margin of error.

As can be seen from the results in the above [Table 4], it can be seen that the lauric acid content of the exemplary composition manufactured according to Manufacturing Example 1 is similar to that of the comparative composition manufactured according to Comparative Example 1. This is because, in the case of Manufacturing Example 1, there is no loss of lauric acid content without going through an oiling process, so it is considered to be economical in terms of cost.

<Manufacturing Example 2 - Manufacturing of feed using insects>

Pet food was manufactured using the insect-based composition and comparative composition manufactured according to Manufacturing Example 1 and Comparative Example 1 of the above [Table 1].

Specifically, the working composition and the comparative composition were each mixed with the feed raw material, and the mixed mixture was kneaded using a rotary kneader. The mixed mixture was molded using a pelletizer. The molded mixture was sterilized at 90°C using a steamer.

Meanwhile, the implementation composition and the comparative composition were each mixed with the feed raw material according to the mixing ratio shown in [Table 5] below.

Implementation Feed Comparative Feed Implementation Composition 40 wt% Comparative Composition 15 wt% flour 40 wt% 38 wt% etc 9 wt% 7 wt% Purified water 11 wt% 40 wt% total 100 wt% 100 wt%

<Experimental Example 3 - Comparison of general nutritional components of feed using insects>

The general nutritional components of the practical and comparative feeds manufactured according to the mixing ratios in [Table 5] above were analyzed.

The results are shown in [Table 6] below.

Implementation Feed Comparative Feed moisture 8.36 % 7.65 % Crude protein 8.71 % 11.12 % Joe's fat 6.35 % 2.60 % Views 9.78 % 10.68 %

Specifically, moisture (AOAC 930.15), crude protein (AOAC 976.05), crude fat (AOAC 954.02), and crude ash (AOAC 942.05) in the composition were each analyzed, and the analysis was performed according to the process analysis method of the Association of Official Analytical Chemists (AOAC).

Referring to the above [Table 6], it can be seen that the crude fat content of the experimental feed increased by more than 3% compared to the crude fat content of the comparative feed.

As can be seen from the results in [Table 6] above, the crude fat content of the practical feed is higher than that of the comparative feed, and this is thought to be because the milking process is not involved.

<Experimental Example 4 - Comparison of fatty acid components of feed using insects>

The major fatty acid components of the practical and comparative feeds manufactured according to the mixing ratios in [Table 5] above were analyzed.

Specifically, the general fat components in the feed were analyzed according to the process analysis method of AOAC 969.33.

The results are as shown in [Table 7] below.

Implementation Feed Comparative Feed Lauric acid 2.65 % 0.98 % Linoleic acid 0.82 % 0.19 % total 3.47 % 1.17 %

Referring to [Table 7], it can be seen that the lauric acid content of the experimental feed increased by more than 1.5% compared to the lauric acid content of the comparative feed.

As can be seen from the results in [Table 7] above, the lauric acid content of the practical feed is higher than that of the comparative feed, and this is thought to be because the milking process is not involved.

<Experimental Example 5 - Comparison of palatability of feed using insects>

A palatability test of the actual feed and comparison feed was conducted.

Specifically, the palatability test was conducted using the two-bowl method. A total of six general companion animals (three dogs and three cats) were fed twice a day at the same time for a total of seven days. The dogs and cats in the free space were presented with the test food and the comparison food in two bowls of the same shape and volume at the same time. The positions of the bowls were changed every day according to the intake day to avoid the selection induced by the feet of the companion animals that frequently used them.

Scoring criteria 1 point 2 points 3 points 4 points 5 points Not eating Just keep your mouth shut Eat a little Eat well Very delicious

The above [Table 8] shows the score evaluation criteria for palatability tests on actual feed and manufactured feed.

The analysis results are as shown in [Table 9] below.

individual Implementation Feed (Score) Comparative Feed (Score) 1 Malsuk (dog) 5 5 2 Congee (dog) 4 4 3 Drop (dog) 4 1 4 Choco (cat) 5 2 5 Pretty (cat) 5 5 6 Toli (cat) 5 4 average 4.7 3.5

Referring to the above [Table 9], it can be seen that the average score of the implemented feed is higher than the average score of the compared feed.

As can be seen from the results in [Table 9] above, it was confirmed that pets had a high preference for the tested feed.
