Abstract
The present invention relates to a protein composition formed of dry matter of a dispersion in which a protein is dispersed in a stabilizer solution, in which the stabilizer includes at least one type selected from the group consisting of a catechol-based stabilizer, 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid, 2,6-di-tert-butyl-p-cresol, 2-tert-butyl-4-methoxyphenol, and 6,6′-di-tert-butyl-4,4′-butylidenedi-m-cresol.

A protein composition comprising:
- dry matter of a dispersion in which a structural protein is dispersed in a stabilizer solution, wherein the stabilizer comprises at least one type selected from the group consisting of a catechol-based stabilizer, 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid, 2,6-di-tert-butyl-p-cresol, and 2-tert-butyl-4-methoxyphenol.
A protein composition comprising:
- dry matter of a solution in which a structural protein and a stabilizer are dissolved,
- wherein the stabilizer comprises at least one type selected from the group consisting of N,N′-hexane-1,6-diyl bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionamide], 1,6-hexanediol bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], 2,6-di-tert-butyl-p-cresol, 3,9-bis(2,6-di-tert-butyl-4-methylphenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane, poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidinyl)imino]-1,6-hexanediyl[(2,2,6,6-tetramethyl-4-piperidinyl)imino]], propyl 3,4,5-trihydroxybenzoate and 4,4′,4″-(1-methylpropanyl-3-ylidene) tris(6-tert-butyl-m-cresol).
A method for producing a structural protein composition, comprising:
- a step of obtaining a dispersion by dispersing a structural protein in a stabilizer solution;
- and
- a step of obtaining dry matter by removing volatile components from the dispersion,
- wherein the stabilizer comprises at least one type selected from the group consisting of a catechol-based stabilizer, 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid, 2,6-di-tert-butyl-p-cresol, and 2-tert-butyl-4-methoxyphenol.
A method for producing a structural protein composition, comprising:
- a step of obtaining a mixed solution by mixing a structural protein, a solvent for dissolving the structural protein, and a stabilizer solution;
- and
- a step of obtaining dry matter by removing volatile components from the mixed solution,
- wherein the stabilizer includes at least one type selected from the group consisting of N,N′-hexane-1,6-diyl bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionamide], 1,6-hexanediol bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], 2,6-di-tert-butyl-p-cresol, 3,9-bis(2,6-di-tert-butyl-4-methylphenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane, poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidinyl)imino]-1,6-hexanediyl[(2,2,6,6-tetramethyl-4-piperidinyl)imino]], propyl 3,4,5-trihydroxybenzoate and 4,4′,4″-(1-methylpropanyl-3-ylidene)tris(6-tert-butyl-m-cresol).
A method for improving heat stability of a structural protein, comprising:
- obtaining a dispersion by dispersing the structural protein in a solution in which at least one type of compound selected from the group consisting of a catechol-based stabilizer, 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid, 2,6-di-tert-butyl-p-cresol, and 2-tert-butyl-4-methoxyphenol is dissolved, and obtaining dry matter in which the structural protein and the compound are both present by removing volatile components from the dispersion.
A method for improving heat stability of a structural protein, comprising:
- obtaining a mixed solution by mixing
- the structural protein,
- a solvent for dissolving the structural protein, and
- a solution of at least one compound selected from the group consisting of N,N′-hexane-1,6-diyl bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionamide], 1,6-hexanediol bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], 2,6-di-tert-butyl-p-cresol, 3,9-bis(2,6-di-tert-butyl-4-methylphenoxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane, poly[[6-[(1,1,3,3-tetramethylbutyl)amino]-1,3,5-triazine-2,4-diyl][(2,2,6,6-tetramethyl-4-piperidinyl)imino]-1,6-hexanediyl[(2,2,6,6-tetramethyl-4-piperidinyl)imino]], propyl 3,4,5-trihydroxybenzoate, and 4,4′,4″-(1-methylpropanyl-3-ylidene) tris(6-tert-butyl-m-cresol);
- removing volatile components from the mixed solution;
- and
- obtaining dry matter in which the structural protein and the compound are both present.
