Abstract

A manufacturing method of flavored feed includes a material preparation step, a freeze-drying step, a crushing step, and a mixing step. The material preparation step is to prepare a feed material and at least one flavored material made from vegetable or fruit. The freeze-drying step is to dehydrate the flavored material by the low-temperature freezing process so as to reduce the water content of the flavored material. The dehydrated flavored material is crushed into flavored pellets in the crushing step. Essential oil of the flavored material can be greatly kept in the flavored pellets during the crushing process to thereby effectively avoid a loss of essential oil caused during the drying process. Finally, the mixing step is to mix the flavored pellets and the feed material evenly into flavored feed to thereby prevent the flavored feed from spoiling and rotting and to postpone the expiration of the flavored feed.

Description

Manufacturing method of flavored feed

The invention relates to a method for producing feed, especially a method for producing flavored feed.

In recent decades, the international aquaculture industry has developed rapidly, especially in countries in tropical regions. While developing aquaculture industry, countries are actively looking for aquatic products that can grow unique flavors to improve aquatic products. additional value; in addition, many consumers buy fish back to eat, in addition to paying attention to whether the fish is fresh, they are more concerned about whether there is a foul or fishy smell.

In Uwajima City, Ehime Prefecture, Shikoku, Japan, the fish farming industry tried to raise about 5,000 amberjacks in a pond with the peel of the local Iyokan. This experiment was originally intended to use the limonene component of the citrus peel to lengthen the freshness of the fish. During the period, a pool of "satsuma fish" with orange fragrance was raised instead. Due to the good results, the purchase price of satsuma fish was 30% higher than that of ordinary fish. Therefore, more and more farmers participated, and even "satsuma fish" "Fish" has become a brand of Uwajima City's aquaculture fish industry, and it is also one of the representative specialties of Ehime Prefecture, the kingdom of tangerines. It mainly includes satsuma yellowtail, satsuma sea bream and satsuma salmon. It has a fishy smell and a hint of orange, which is loved by women and children.

According to the survey, the general feeding method of mandarin fish is to chop up citrus peel and mix it with the feed, and gradually increase the mixing ratio of citrus peel in the feed, so that the farmed fish will gradually get used to adding feed with special flavor; in addition, in There are also breeders in China who use lemons to squeeze out lemon juice, and then mix it with the feed to form a flavored feed to feed fish with a lemon flavor; etc., it is easy to have the following deficiencies:

1. Uneven mixing: The aforementioned additives such as citrus peel or lemon juice are directly crushed from fresh fruits, so the water contained in these additives often depends on the additives , and these additives in the form of fruit pellets are mixed with the feed at the beginning, causing some of the feed to absorb the moisture of the additives excessively, even if it is combined with the subsequent mixing, it is impossible to make the feed and the additives It is in a uniform state, so more of these additives must be added to achieve the desired feed mixing state, which will increase the amount of these additives invisibly, resulting in an increase in feed costs, which really needs to be improved.

2. The nutrients of these additives are easy to lose: these additives, such as lemons, must first be squeezed to obtain lemon juice before they can be added, but the essential oil of the lemon skin is directly squeezed , It is easy to cause the essential oil of the lemon skin to disappear, and the composition content of the lemon is reduced virtually, which is not complete for the composition of the feed.

3. Difficulty in preservation: After mixing the feed with the additives, the juice has a certain shelf life at room temperature after the juice is squeezed out of the additives, and the juice will easily rot and deteriorate if the time limit is exceeded. Breeding has a certain impact, so it is easy to be restricted in use, so it is not easy to store.

Therefore, the object of the present invention is to provide a method for producing flavored feed, which can preserve the essence of flavor raw materials intact, and at the same time fully mix with feed more evenly, and have a longer service life after mixing.

Therefore, the present invention provides a method for producing a flavored feed, which includes a material preparation step, a freeze-drying step, a crushing step, and a mixing step; wherein, in the material preparation step, there is a feed and at least one flavor raw material of vegetables and fruits, Then freeze the flavor raw material first, so that when the moisture in the flavor raw material is lost during the freezing process, the loss of essential oils and nutrients in the fruits and vegetables can be reduced, and the preservation time can be extended when the moisture is reduced. The subsequent crushing step The vegetables and fruits are directly broken into vegetable and fruit granules, and finally the vegetable and fruit granules are mixed with the feed to complete the production. In this way, the vegetable and fruit granules can be mixed with the feed more uniformly, and the combination effect of the vegetable and fruit granules with the feed can be improved , and the vegetables and fruits or the feed combined with vegetables and fruits can also be kept for a long time.

The aforementioned and other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of preferred embodiments with reference to the drawings.

Referring to Fig. 1, the first preferred embodiment of the present invention, the manufacturing method 3 of flavored feed of the present embodiment, it comprises material preparation step 31, freeze-drying step 32, crushing step 33 and mixing step 34; Wherein, the material preparation step 31 There is a flavor raw material and a feed, the feed is different according to the species of cultured fish, and in the best case, the characteristics of the feed can be general dry granular feed or plant feed, etc.; in addition, The flavor material is selected from at least one vegetable and fruit, such as lemon, citrus, tomato, wasabi, kiwi, banana, strawberry, pomelo, or a combination thereof, and can also be used whole or cut into pieces .

Continuing from the above, the freeze-drying step 32 is to use a freeze-drying device. After the flavor material is put into the freeze-drying device, the moisture in the fruits and vegetables can be made from solid ice in a high vacuum and low temperature environment. The water vapor sublimated into a gaseous state is condensed into liquid water and removed, thereby reducing the moisture in the fruits and vegetables, and reducing the moisture to below 20% (inclusive), and the best freezing temperature is below -18 degrees At the same time, when the water content of the fruits and vegetables is reduced, the preservation of the fruits and vegetables can be relatively prolonged, and through the freeze-drying process, most of the nutrients and essential oils in the fruits and vegetables can be preserved in the fruits and vegetables without due to The temperature of the treatment process causes the loss of essential oil; in addition, the crushing step 33 can use a crusher to crush the above-mentioned freeze-dried fruits and vegetables, and in a dry state, crush the fruits and vegetables through the crusher to make the fruits and vegetables Vegetables and fruits are easier to be broken into multiple vegetable and fruit particles without forming a soft state, so during the crushing process, it can better retain the essential oils and nutrients in the vegetables and fruits in the vegetable and fruit particles, reducing the loss during the manufacturing process. , The particle size of the vegetable and fruit particles can be crushed to a size that can be mixed with the feed, so the size of the particle size can be adjusted according to the size of the farmed fish and the matching feed.

Continuing with the above, the mixing step 34 uniformly mixes the above-mentioned crushed vegetable and fruit particles with the feed, and presents a particle dispersion state through the vegetable and fruit particles, which can be more easily and uniformly mixed in the feed; as for the vegetable and fruit particles The mixing ratio with the feed is adjusted according to the culture status and fish species, so the mixing ratio is not the technical content that this case focuses on; therefore, through the manufacturing method 3 of the flavored feed of the present invention, the fruits and vegetables can be freeze-dried in advance , which can prolong the storage time of the fruits and vegetables, and at the same time, when it is desired to feed, the fruits and vegetables are crushed into a plurality of fruit and vegetable particles after the freeze-drying step through the crushing step 33, and then can be added to the feed for mixing , can mix the vegetable and fruit pellets with the feed more evenly, and improve the combination quality of the vegetable and fruit pellets and the feed. Moreover, when the moisture content of the vegetable and fruit pellets is low, they can be mixed with the feed immediately Compared with the conventional mixed state of using squeezed juice or directly using the peel, the present invention can be preserved for a longer time as a whole.

To sum up the above, the manufacturing method of the flavored feed of the present invention comprises a feed and at least one flavor material of fruits and vegetables, and then freeze-dries the flavor materials, so that the essential oils and nutrients in the fruits and vegetables can be lost under the condition of low loss. Reduce the moisture in the fruits and vegetables, and then directly break the freeze-dried fruits and vegetables into vegetable and fruit particles, and finally mix the vegetable and fruit particles with the feed; In the dry state, the juice loss in the vegetable and fruit can be avoided in the crushing step. Finally, in the mixing step, because the vegetable and fruit particles are still in a dry state, the vegetable and fruit particles can be more evenly mixed with the feed during the mixing process. Mix, and then make this flavor raw material and this feed combine effect better, so can really reach the purpose of the present invention.

But the above is only to illustrate the preferred embodiments of the present invention, and should not limit the scope of the present invention, that is, all the simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the description of the invention , should still fall within the scope covered by the patent of the present invention.
