Definitions
- the present invention relates to a method for improving the gelling property of protein by electron beam irradiation, a protein treated by the method, a method for gelling a protein having an improved gelling property by electron beam irradiation, and these methods. And a product containing the protein obtained by the method of (1).
- Proteins are destroyed by heat, denaturing agents such as guanidine hydrochloride and urea, or organic solvents such as ethanol, causing so-called denaturation.
- denaturation of a protein by heat treatment does not involve disruption of peptide bonds contained in the primary structure, but changes the tertiary structure at the secondary, tertiary, and quaternary levels.
- Aggregation refers to the regular formation of a protein network.
- Such a phenomenon can be defined as gelation and is thought to be caused by the interaction between proteins.
- heat denaturation during the manufacturing process is prevented by adding sugar or sugar alcohol to raise the temperature at which protein is denatured, or by adding salts such as sodium salt to salt out. Is planned.
- desalting treatment removes excess ions and calcium ions that are contaminants to obtain a clear protein solution, or removes metal salts using a chelating agent such as citrate or polymerized phosphate.
- the method of preventing denaturation is also adopted You. However, none of these methods alters the properties of the protein itself, but merely adjusts the gelation due to thermal deformation by adjusting the conditions of the surrounding environment.
- proteins are denatured by heat and gelled as a result, resulting in functional properties such as not only viscoelasticity but also water absorption, denseness, improved particle binding, adhesion, emulsification and foam stabilization. Is generated. For this reason, protein gelation is important in the production of food products such as various dairy products, coagulated egg white, gelatin protein, heat-coagulated products of minced meat and ground fish, soy protein, and extruded vegetable protein and bread dough. Role.

- gelation is also performed by making a protein alkaline once and then neutralizing or adjusting the pH to the isoelectric point.
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, it was possible to improve the gelling properties of proteins by irradiating protein with an electron beam. It has been found that proteins that are transferred to a region above the temperature or gelled at a higher rate than the original rate can be obtained.

- the method of the present invention is performed by irradiating a protein with an electron beam.
- the electron beam is usually generated from an electron beam generator, for example, a linear electron accelerator, a van de Graaff electron accelerator, or an area beam. Or an electron beam generator of Cockcroft-Walton type or the like.
- the acceleration voltage applied to the electron beam is in the range of 50 KeV to 10 MeV, preferably 300 KeV to 5 MeV, more preferably 300 KeV to 2.5 MeV.
- Expected effects cannot be obtained with an electron beam to which an accelerating voltage of less than 50 KeV is applied, and the use of an electron beam with an accelerating voltage of more than lOMeV to food is prohibited.
- dose rate ⁇ ⁇ 5 -. 1.0xl0 refers to the range of 9 Gy / hr.
- the protein to be irradiated with the electron beam may be in a dry state or in a state of being dispersed in water, but in order to sufficiently irradiate the electron beam, the protein is in a dry state, and is in the form of a film or a plate. It is preferably in the form of granules or powder.
- irradiating a protein dispersed in water with an electron beam it can be solidified by spray-drying, drum-drying, hot-air drying or the like after irradiation, if necessary.
- the electron beam can be directly or indirectly applied to the protein.
- the film has a thickness such as a plastic container through which the electron beam can pass, preferably a polyethylene bag. Irradiation can be performed in an 80 m container. At this time, the thickness can be appropriately adjusted depending on the specific gravity of the protein, and is preferably adjusted between 5 to 10 thighs, and the irradiation can be easily performed.
- Irradiation with an electron beam can be performed in the presence of air in a closed system or in the presence of air, oxygen gas or nitrogen gas in a closed system, and in the presence of alcohol such as water or ethanol. You may.
- the present inventors By irradiating an electron beam as described above, the present inventors It has been found that the gelling property of the protein is improved, and in particular, the gelling temperature of the protein is shifted to a higher temperature region than the original gelling temperature, or the ratio of the gelled protein is increased from the original ratio. .
- the gelation temperature is higher than the original gelation temperature under the same conditions due to electron beam irradiation. Transferred to temperature.
- egg white that gels when heated, it has the property of gelling under cooling conditions after heating by electron beam irradiation, and its gelation temperature is higher than the original gelation temperature under heating conditions. Moved to the area.
- the percentage of gelling protein is increased from the original percentage.
- the “gelation temperature” means the temperature at which the protein gels
- the “proportion of the gelled protein” refers to the property of gelation of protein molecules in all evening.
- the protein irradiated with an electron beam according to the method of the present invention does not have the roughness or viscosity inherent to gelation at the original gelation temperature due to the change in the gelation temperature, and not only is easy to handle, but also On the other hand, an increase in the proportion of gelling protein increases the amount of water added, thereby providing a product having good water retention.

- the thermal stability of the protein is improved, and the floating of aggregates and A viscous thickened material or a good foamed material can be obtained without roughness.
- the desired gel strength can be adjusted by arbitrarily setting the amount of heat-resistant protein to be added, and a product having good emulsifiability can be obtained.
- enzymes and carrageenans such as thickening polysaccharides conventionally used for gelling and saccharides, salts, chelating agents, etc. added for adjusting thermal denaturation are not required, and excessive Use of quantities of additives 3 ⁇ 4 can be avoided.
- these additives may be used in the method of the present invention. Can be assured.
- the electron beam irradiation gives 1 J of energy per kg of protein, for example, by irradiation with an absorption dose of 1 kGy. For this reason, it is also presumed that the energy absorbed by the aromatic amino acid or the like excites the amino acid in an energy-like manner, resulting in a more stable quasi-excited structure.
- the protein irradiated with the electron beam can be gelled according to a method well known in the art to obtain a protein gel having the above properties.
