JPS6163250A - Production of feed having high lysine content - Google Patents

Abstract

PURPOSE:To obtain the titled feed preserbable for a long period, having high nutritive value and good nutrition balance, by dehydrating chicken and bony parts of fish under reduced pressure by the use of a hot oil as a heating medium, to give chicken flour meal and fish flour meal, respectively, and blending them. CONSTITUTION:Chicken and bony parts or soluble parts of fish are dehydrated under reduced pressure by the use of an oil at >=90 deg.C, a temperature where protein and gelatinous substance is not dissolved in the oil but thermally coagulated, made into chicken flour meal and fish flour meal, respectively, and they are blended to give the aimed feed.

Description

[Detailed Description of the Invention] (a) Industrial first-use valve lrI The present invention relates to a method of manufacturing a high-grade gin-containing valve.

(0) Prior Art Chicken powder meal conventionally used as feed had a low lysine content, low nutritional value as feed, and poor nutritional balance.

(c) Problems to be solved by the invention Therefore, when using chicken powder meal as feed, it is necessary to also use feed containing high lysine, but when feeding, two or more parts of feed must be added. However, it was troublesome to use it in advance.

Therefore, it is best to mix two or more types of feed from the beginning, but since chicken meal becomes highly perishable due to the presence of moisture, it is best to use highly dehydrated feedstuffs containing high lysine. It was not profitable in terms of cost as it had to be done by ronin.

(2) A method for solving the problems In the present invention, chicken powder is prepared by dehydrating chicken meat under reduced pressure conditions using heated oil as a heating medium, and a high-lysine compound containing fish meat or soluple is used. is similarly dehydrated using heated oil as a heat medium to form fishmeal meal, and y! It is an object of the present invention to provide a method for producing feed v1 containing high lysine, which is characterized by mixing A flour meal and fish meal meal.

(Small) Effect In the present invention, chicken meat is heated using heated oil as a heat medium.
Since the chicken meal is dehydrated at the bottom, the dehydration can be completed completely, the processing time can be reduced, and the cost can be reduced.

In addition, since the fish meal or solubles that contain high lysine are made into fishmeal meal using heated oil as a heating medium, it is possible to completely produce flf2 water, shorten the processing time, and further reduce the cost. can be achieved.

In this way, by mixing high lysine-containing fish meal with chicken meal, a feed with high nutritional value and good nutritional balance can be produced at low cost. In addition, since both chicken meal meal and fish meal meal are completely dehydrated by oil crystal dehydration, there is no risk of dryness even if the two are mixed.

(f) Effects Therefore, since the complete dehydration process is carried out, the mixing of chicken meal and fish meal can be carried out in a state that can be stored for a long period of time, and the feed can be easily supplied at a low cost. Nutrition 1
The effect is that it is possible to produce fil f:1 with a high surface content and a good nutritional balance.

(g) Example Embodiments of the present invention will be described in detail as follows.

That is, animal oil, vegetable oil,
Add oil such as mineral oil, animal fat, vegetable oil, etc., and heat the oil to 90°C or higher, which is the temperature at which protein and gelatin coagulate without being dissolved in the oil. Raw material chicken meat cut into large pieces or shredded in this heated oil 5
Add 00ko, let it soak, and close the lid.

Such a vacuum treatment is carried out under a small vacuum condition where proteins are likely to thermally coagulate, that is, a vacuum of 10 to 2 QnvH (I), for the initial 30 minutes or so after immersing the raw chicken meat in heated oil, and then under a large vacuum condition. , i.e. 740-750mm)-1a
This treatment is carried out for approximately 60 minutes under reduced pressure and approximately empty conditions to dehydrate the material to a moisture content of approximately 3 to 6%.

Therefore, in the first time of true pressure, the oil temperature is 90℃ or higher, and the oil temperature is 10~
・Due to the small decompression conditions of 20mmt-10, the original n
The water-soluble protein of chicken 7ζ and piratin 71 are carefully stabilized. Prevents the leakage and decomposition of flavor components, and furthermore, prevents the leakage and decomposition of flavor components.
It has a structure that prevents the leakage of various vitamins.

In addition, 740-7 with hb temperature of 90℃ or higher and midway through decompression
50mmt-1! ], the moisture contained in the raw chicken meat is dispersed and replaced with heated oil, which penetrates deeply into the tissue of the heated oiled chicken. Then, the chicken is heated in heated oil from both the outside and the inside of the rug, and dehydrated in a short period of 0+1, allowing water-soluble protein, gelatin, vitamin △, vitamin C, etc. to be extracted. It is possible to prevent bicumins from being denatured, decomposed, and leaked (114), and measures are also taken to denature and destroy basic nitrogen in tissues by the temperature of fats and oils.

Next, the dehydrated product is taken out of the heated oil and deoiled by pressing with a screw press or core separation, and then the oil is removed by n-hexane spraying on a mesh conveyor to completely remove the oil. It is something that does oil.

And then, what about grinding it and making it into chicken powder meal? j.

In addition, fish grits or solubles, which are low cost and contain high lysine, are dehydrated using heated oil as a heating medium in the same manner as in the case of chicken meat, and the oil is removed and pulverized to form fish meal meal.

Next, mix chicken powder meal and fish powder meal at appropriate times and feed it.

Claims (1)

[Claims] 1) Chicken meat is immersed in oil preheated to 90°C or higher, which is the temperature at which protein and gelatin coagulate without dissolving in the oil, and dehydrated using the heated oil as a heat medium while reducing pressure. At the same time, fish meal, which is a high lysine-containing substance, is dehydrated using heated oil as a heating medium to form a fish meal, and the fish meal and chicken meal are mixed to make feed. A method for producing feed containing high lysine.
