Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a compound food or a compound feed containing soy protein fiber as a main raw material. The complex food or complex feed of the present invention refers to a product obtained by adding various food materials or feed additives to soybean protein fiber and subjecting it to various processes.

2. Description of the Related Art In producing a complex food product of various food materials suspended in water or an aqueous medium and soybean protein fiber,
First, the above-mentioned food material suspended in water or an aqueous medium is filtered with a non-edible filter medium, dehydrated or sieved, and the food material attached to the filter medium surface or on the sieve is taken out separately and mixed with soybean protein fiber again. However, a method of processing is usually considered.

[0003] For example, in the case of producing a composite food product of a food material such as vegetables and meat and soybean protein fiber, an aqueous medium containing seasonings, colorants and the like is first added for the purpose of seasoning and coloring. After suspending, it is filtered with a non-edible filter medium, and the above food material adhering to the surface of the filter medium is mixed with soy protein fiber,
A method of forming a composite food containing soybean protein fiber as a main raw material by performing processing such as molding and heating is adopted. Also, food materials such as okara, sake lees for wasabi pickles, tatami sardines, and seaweed are
It is usually suspended in various aqueous media, and in handling these, it is dehydrated with various inedible filter media, and then the above food material adhering to the surface of the filter media is mixed with soy protein fiber, and laminated, arranged, etc. It is conceivable that the above-mentioned processing is carried out to form a composite food containing soy protein fiber as a main raw material.

On the other hand, in producing a composite feed of a feed additive suspended in water or an aqueous medium and soybean protein fiber,
First, the above-mentioned feed additive suspended in water or an aqueous medium is filtered with a non-edible filter medium, dehydrated or sieved, and the feed additive attached to the surface of the filter medium or on the sieve is separately taken out, and the soybean protein fiber is regenerated. A method of mixing and processing with is usually considered.

For example, when a composite feed of feed additives such as chlorella powder and soybean protein fiber is to be produced, it is first suspended in water and then inedible in order to uniformly disperse it in soybean protein fiber. A method is employed in which the above-mentioned feed additive adhering to the surface of the filter material is mixed with soybean protein fiber and subjected to processing such as pulverization to obtain a composite feed containing soybean protein fiber as a main raw material. In addition, feed additives such as chlorella and spirulina are usually suspended in their culture solution.In handling these, after filtering with various inedible filter media, the above-mentioned feed additives attached to the filter media surface are added. It is conceivable that the product is mixed with soybean protein fiber and subjected to processing such as granulation to obtain a composite feed containing soybean protein fiber as a main raw material. Furthermore, when using silage, in addition to raw grass and root vegetables, starch meal, okara, etc. may be used in combination with silage, and since a large amount of water is discharged as it is, it is dehydrated with a non-edible filter medium. Alternatively, a method may be considered in which the silage accumulated on the surface of the filter medium is separately taken out, mixed again with soy protein fiber, and processed.

[0006]

In the food processing or feed manufacturing process, it is important to reduce the number of processes as much as possible and increase the efficiency. Conventionally, the step of separating the food material or the feed additive by filtering, dehydrating or sieving as described above and the step of mixing them with soy protein fiber and subjecting them to processing such as lamination and arrangement are separately performed. There is a problem in that it is necessary, the number of steps is large, and it is troublesome. So far, there is no known means that can effectively solve such a problem.

Therefore, it is an object of the present invention to provide a method for producing the above-mentioned product which has fewer steps and is more efficient than the conventional method in producing a complex food or a complex feed containing soybean protein fiber as a main raw material. .

[0008]
