JPS5925648A - Recovery of protein source - Google Patents

Abstract

PURPOSE:To recover a powder protein source and to enable the recovery of the protein source having low hydroscopicity, slightly being coagulated, by boiling and steaming fishes and shellfishes, bones, skin, and meat of animals with water, concentrating them, dehydrating them in a hot animal or vegetable oil, removing the oil from them. CONSTITUTION:Raw materials such as fishes and shellfishes, bones, skin, and meat of animals are boiled and steamed with water, or steamed with live steam at 110-130 deg.C with applying 2-5K pressure, water-soluble protein is eluted in hot water, and recovered as jelly. It is put in a vacuum evaporator, boiled at about 40-60 deg.C, water is evaporated, the water content of the jelly is made<= about 40wt%, it is immersed in a hot animal or vegetable oil, dehydrated at about 120 deg.C oil temperature, and the water content is made about 6wt%, and protein crystal contained in the concentrated jelly is precipitated in the oil. The precipitated protein crystal is taken out, sprayed with a solvent such as n-hexane, etc. so that the oil is removed, to recover a powder protein source.

Description

[Detailed description of the invention] This invention relates to a protein resource recovery method.

Conventionally, when recovering protein resources for use as seasonings 131 or other raw materials 1, if they were recovered in powder form, they would be highly hygroscopic and coagulate. , animal bone broth, etc. J Rudo, protein resource recovery center J11! 'FF 1) has a drawback that makes it difficult to operate smoothly.

In this invention, seafood, animal bones, etc. are steamed in water, the broth is taken out, and the water content is about 40% by boiling the boiled water in one curve.
11j (water, 2nd oil)
Next, it is dehydrated and separated and treated with water to ensure smooth circulation of the powdered protein resource, and has low hygroscopicity and 0 coagulation

If we describe the embodiments of this invention in detail, firstly, we will first explain the processing method using seafood, animal bones, etc.

It is possible to recover the protein resources such as oil and protein resources, and these protein resource IJ) powders can be used as seasonings, other quality products, raw materials such as feedstones, and thickeners. It's something to be excited about. In addition, when using the punch 14, remove the oil by centrifuging the oil.

In order to pass through the two-stage dehydration treatment process of first dehydration and 12th dehydration, sea urchins undergo a truly complete 111 (water treatment Iψ) process, such as when drying. After dehydration is completed, the hygroscopicity of the rice product is slow, and the wood-like protein resources absorb moisture.
C Prevents coagulation - Good quality, and the product itself is high quality! J
In trade, it can be used for various purposes such as seasoning 1'+1, feed, fertilizer, etc. Furthermore, in water treatment, since it is vacuum In2 water, Secondary dehydration completes i':,'i 15) Wood-like and 1-stage V) 1
Since water treatment can be performed, there is no effect on the source product tT, and it is effective in preventing thermal transformation.
