Definitions
- the present invention relates to an improved gluten capable of imparting excellent freezing resistance to food dough, particularly bread dough, a method for producing the same, and use of the improved gluten.
- Patent Document 1 discloses a method of preparing a gluten-modified product having water absorption and emulsifying properties by adding gluten to an acidic aqueous solution to prepare a gluten dispersion and heat-treating the aqueous solution of lactic acid. It is described that bread prepared by adding a modified gluten product to dough has excellent extensibility and a soft texture.
- Patent Document 2 a thickener having a charge is added to an acidic dispersion of gluten having a pH of greater than 2.0 and less than 5.0 to obtain an aggregate with gluten, and then the aggregate
- Patent Document 3 discloses that gluten having a high processing property is obtained by subjecting gluten dispersed in an acidic solution having a pH of 2.0 to 6.0 to heat-denaturation treatment at 60 to 160 ° C. and then drying.
- a method for producing a dry powder is disclosed.
- none of these documents discusses the freezing tolerance of bread dough and the breadth of bread after baking.
- the acid used for the preparation of the acidic aqueous solution to which gluten is added is not limited as long as it can be adjusted to a predetermined pH, and organic acids or inorganic acids can be widely used (for example, Patent Document 1). Paragraph 0025, Patent Document 2 Paragraph 0020).
- Bread is generally manufactured through processes such as preparation, chaos, division, bench time, molding, proofing, and baking. Frozen bread dough is frozen and stored in the middle of this bread making process, once production is interrupted, then thawed, and after final fermentation, baked and used. By using frozen bread dough, work efficiency is greatly improved. Is possible. However, frozen bread dough does not sufficiently swell in the final fermentation because the gluten network in the dough is destroyed due to growth of ice crystals during frozen storage and the dough weakens and does not swell enough in the final fermentation. In addition, there is a problem that the appearance, texture, etc. are inferior to bread that is not subjected to frozen storage called the scratch method.
- the properties of gluten are improved by oxidizing the thiol group of gluten using an oxidizing agent such as L-ascorbic acid and promoting the formation of disulfide bonds. It is practiced to have a freezing tolerance. However, when L-ascorbic acid is added to the dough raw material so that the effect of freezing resistance is exerted, the dough is tightened and the elongation becomes worse.
- an oxidizing agent such as L-ascorbic acid
- JP 2014-198037 A Japanese Patent No. 4168102 Japanese Patent Publication No. 52-24579 Japanese Unexamined Patent Publication No. 63-079552
- An object of the present invention is to provide an improved gluten capable of imparting excellent freezing tolerance to bread dough and a method for producing the same.
- the present invention relates to the following (1) to (7).
- a process for producing improved gluten (2)
- a solution containing gluten and an organic acid having two or more carbonyl groups in the same molecule with respect to 100 parts by weight of the gluten is heated at 70 ° C. or more for 30 minutes or more.
- a method for producing bread dough comprising a step of preparing bread dough using the obtained improved gluten.
- a solution containing gluten and an organic acid having two or more carbonyl groups in the same molecule with respect to 100 parts by weight of the gluten is heated at 70 ° C.
- a method for producing bread comprising a step of preparing bread dough using the obtained improved gluten and a step of baking the prepared bread dough.
- a solution containing gluten and an organic acid having two or more carbonyl groups in the same molecule with respect to 100 parts by weight of the gluten is heated at 70 ° C. or more for 30 minutes or more.
- a method for improving physical properties of bread comprising adding the obtained improved gluten to a dough raw material.
- the method according to (4), wherein the improvement of physical properties of bread is improvement of breadiness of bread.
- Improved gluten obtained by heat-treating a solution containing gluten and an organic acid having two or more carbonyl groups in the same molecule with respect to 100 parts by weight of the gluten at 70 ° C. or more for 30 minutes or more .
- an improved gluten capable of imparting excellent freezing resistance to food dough, particularly bread dough, and a method for producing the same are provided.
- the improved gluten of the present invention By adding the improved gluten of the present invention to bread dough, the deterioration of the gluten network due to freezing storage is suppressed, and a bread having a high volume and a good shape can be obtained.
- the amount of water absorption can be increased by adding the improved gluten of this invention to bread dough, the cost reduction and the improvement effect of food texture are also acquired.
- the dough made with L-ascorbic acid added to have freezing resistance is too strong, for example, in a roll bread, it is easy to generate a forming error that the formed dough is “rolled”.
- the improved gluten of the invention provides freezing resistance and at the same time maintains the stretchability and elasticity of the dough. Further, by using the improved gluten of the present invention, for example, it is not necessary to prepare a moisture content different from that of the dough for the scratch method (method of straightening from kneading to baking / straight cooking method) that is not usually frozen during production. In both cases, the frozen dough can be frozen resistant, so the scratch dough and the dough for frozen dough can be manufactured on the same production line with the same formulation without distinction, improving work efficiency and productivity To do.
- Implementation product A (powder A: succinic acid-treated gluten used), implementation product B (powder B: malate-treated gluten use), implementation product C (powder C: citrate-treated gluten use), additive-free product, comparative product 1 ( The appearance of a baked roll bread obtained by baking each dough of untreated gluten) after freezing storage for 14 days is shown.
- Example product D (powder D: using malonic acid-treated gluten)
- Example product E (powder E: using succinic acid-treated gluten)
