Abstract

PURPOSE:To obtain a thermally dried protein source which can be dissolved in water or hot water, by thermally drying a protein raw material using an animal oil or a vegetable oil. CONSTITUTION:A raw material of protein such as animal, fish, shellfish, etc. is immersed in an animal or vegetable oil heated at about 120 deg.C, and heated while reducing the pressure in two steps, i.e. initial evacuation and final evacuation. The protein contained in the raw material is thermally dried and dehydrated by the process, and a thermally dried protein having a water content of about 6% is recovered from the oil. The product is deoiled by conventional method to obtain a thermally dried powdery protein which can be dissolved when heated in water or in hot water.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for re-elution of a heat-coagulated protein source.

Conventionally, as a method for recovering proteins from animals, fish, and shellfish, etc., the protein is thermally coagulated and then recovered in the form of powder.If the protein is not to be dissolved in water or hot water and used as a flavoring agent or a nutrient source, - Proteins, etc. coagulated by heat coagulation do not dissolve in water, hot water, etc. again, but settle at the bottom, and cannot be used in a state dissolved in water, hot water & C. Even if it is boiled, the protein cannot be eluted into the broth, which has the disadvantage that it cannot be used again for other processing.

In this invention, animal oil or vegetable oil is heated, proteins contained in raw materials such as animals, fish and shellfish are thermally coagulated through the heated oil, and at the same time, the contained water is evaporated to perform dehydration treatment, and then After removing the oil, the powder-like heat-coagulated protein source is collected, and the collected powder-like protein source is reheated in water or hot water to obtain the heat-coagulated protein source in boiling broth or hot water. By redissolving the protein source, the thermally solidified protein source can be easily eluted in a reheating treatment step in water or hot water.

It is an object of the present invention to provide a method for re-eluting an fc heat-coagulated protein source, which has a wide range of processing applications and allows effective use of the protein source.

To explain in detail the embodiments of this invention, first, animals, fish and shellfish are used as raw materials, and sb, for example, mackerel,
Sardines, animal meat such as pigs and cows, animal bones, snakes, stinging turtles, earthworms, etc.

The raw material is immersed in preheated animal oil or vegetable oil.The oil temperature is around 120C, the raw material is placed in the oil, immersed, stirred, and heated at the oil temperature for about 1 to 8 hours. The water contained in the raw materials evaporates and dehydrates, and the proteins, especially water-soluble proteins, contained in the raw materials are thermally coagulated and solidified without being eluted into the oil.

Next, the moisture content is set to around 6%, the P raw material is recovered from the oil, the oil is deoiled using a press, and the fat content is deoiled using a deoiling agent such as normal hexane. When this protein is heated in water or hot water, the protein is dissolved in the water or hot water, and the protein that has been coagulated by heat is recovered as eluted as a broth or as a protein-dissolved liquid. It can be processed for both drinking and flavor purposes.

In addition, the broth produced by steaming powdered protein can be stored for a long time by rapid freezing, and just by pouring hot water, a broth-like solution with dissolved protein can be produced instantly. can.

In addition, when heating raw materials in oil to oil temperature, heating under reduced pressure conditions while immersed in oil will further speed up thermal coagulation of the protein and improve dehydration efficiency. In particular, the pressure reduction conditions are set in two stages, and the initial pressure reduction, that is,
The pressure was reduced to 10 to 20 mmHg for about 80 minutes after inputting the raw materials, and then the pressure was reduced to 740 to 750 mmHg.
Performing vacuum dehydration prevents the elution of water-soluble proteins into oil,
Rapid thermal solidification becomes possible.

According to this invention, the raw protein is thermally coagulated using animal oil or vegetable oil, and at the same time dehydrated using the oil temperature, so that the thermally coagulated protein can be redissolved in water or hot water. If Kaloe treatment is performed, it can be recovered as broth, which has a wide range of processing applications and can be used for beneficial purposes, and it is also easy to use the dissolved protein extract components of animals, fish and shellfish for flavoring purposes, cooking purposes, and nutritional sources. It has the effect that it can be used as such.
