This invention relates to a method for manufacturing bakery products. Various attempts have been made to add soybean protein in the production of bakery products such as bread. The background to this is that the protein content in wheat flour is not very high, so it is desirable to increase the protein content by adding high-protein ingredients, and the balance of essential amino acids that make up wheat protein is not perfect, especially lysine. Due to the lack of protein, there is a need to increase the protein score by reinforcing protein materials rich in protein. However, at present, attempts to obtain bakery products by adding soybean protein have not yielded results that are satisfactory in terms of bread quality, apart from the nutritional standpoint. Firstly, the addition of high protein ingredients increases the protein content in the dough and inevitably reduces the relative proportion of wheat protein, resulting in loss of product mass volume and
Poor appearance becomes noticeable. Second, among various soybean proteins including soybean protein, for example, defatted soybean flour is preferred to full-fat soybean flour, and isolated soybean protein is preferred to defatted soybean flour. On the other hand, if low-purity soybean protein is used, there is a problem in that bakery products will have a soy odor and taste, and the effect of increasing the protein content will be small. The present inventor, while conducting various studies on the production of protein-enriched bakery products that better suppress loss of product mass volume and deterioration of appearance, found that when soybean protein is added, We have learned that it is extremely important to avoid contact with water, and as a result, even when using highly purified soy protein such as isolated soy protein, we can produce products with good lump volume and appearance. This invention was completed based on the knowledge that bakery products can be made to have a high protein content with almost no flavor limiting factors. That is, the present invention provides a method for producing a bakery product, the gist of which is to mix soybean protein with an oily substance in advance in a non-hydrated system and then use it as a component of flour dough;
It is. In this invention, soybean protein is full-fat to defatted soybean flour,
Tofu powder, powdered soy milk, concentrated soy protein powder, isolated soy protein powder, etc. are used, and these may or may not have been subjected to heat treatment or alcohol treatment to lower their NSI (Soluble Nitrogen Index). , used in dry or powdered form. Isolated soybean protein is most preferable in terms of soybean odor and taste, and if soybean protein is hydrolyzed, it becomes more preferable in terms of flavor and provides a bakery product with excellent texture. Hydrolysis rate (0.22 mole trichloroacetic acid soluble nitrogen/total nitrogen x 100 (%)) is effective when it is about 5% or more, and when it exceeds about 20%, it results in a slightly bitter taste. In this invention, the oily substances are animal and vegetable fats and oils, their hydrogenated oils, fractionated oils, transesterified oils, or ski tonings and margarines made from these as raw materials, and when they contain a phase other than lipids, such as margarine, an external phase is used. That is, only when the continuous phase is lipid. The oily substance may be liquid, plastic, or solid at room temperature, but solid substances are preferably mixed in a temperature range from liquid to plastic. The structure in which soybean protein and oily substances are mixed in advance in a non-hydrated system is the most characteristic part of the production method of the present invention, and unlike conventional methods, soybean protein powder is not added at the same time as wheat flour and water. This is different from the addition method in which soy protein powder is brought into direct contact with water, such as by emulsifying soy protein powder with water in advance. In other words, the conventional method of adding soybean protein is to bring it into direct contact with water together with other raw materials as a powder, but in addition to the above-mentioned drawbacks, this also has the drawback that it is difficult to homogenize the dough. In order to facilitate homogenization, a method has been devised in which soybean protein powder is emulsified with water in advance and then added. However, the addition method of the present invention has the effect of suitably suppressing the loss of product mass volume and poor appearance caused by the addition of high protein materials, and
In addition, there is almost no difficulty in making the dough uniform or in reducing the viscoelasticity of the dough. This is because soybean protein, which is naturally highly hygroscopic, is covered with an oily substance upon contact with water, etc., which makes all ingredients compatible with water and inhibits the function of non-wheat protein against wheat protein. It is thought that the effect is to suppress the By the way, "mixing in a non-hydrated system" means that no water is added to anything other than the soybean protein and the oily substance, and the dry or powdered soybean protein usually contains a few percent. This does not mean to exclude a certain amount of water, or even about 10% of water that may exist as an internal phase of oily substances, and of course, the flour dough that is prepared also contains water. The ratio of soybean protein and oily substance to be mixed in advance is such that if the ratio of the former is too low, there is a limit to the amount of oily substance that can be used as a raw material for bakery products.
If the latter ratio is too low, it will be difficult to achieve the goal of high protein content, and soybean protein will be difficult to be covered with oily substances. The amount of oily substance used as a raw material for bakery products varies depending on the type of product intended, and the amount of oily substance sufficient to cover soybean protein depends on whether the oily substance is liquid or plastic. Therefore, although there are some differences, if the total ratio of soybean protein to oily substance is within the range of 2:3 to 4:1, it will work well regardless of the type of bakery product intended or the type of oily substance. It has the versatility of being able to provide high protein content, and
Within this range, even if the oily substance is in liquid form, it will exhibit plasticity by mixing it with soybean protein.
Since the two are difficult to separate, workability is also good. The mixture may further contain small raw materials contained in ordinary bread-making raw materials, such as emulsifiers such as lecithin, monoglyceride, and sorbitan fatty acid ester. When these emulsifiers are used, the appropriate amount is in the range of about 0.1 to 1% based on the oily raw material. Any method for mixing soybean protein and oily substance can be used as long as each particle of soybean protein powder etc. is sufficiently dispersed in the oily substance. Alternatively, a continuous mixer is sufficient. Since the mixture of soybean protein and oily substance obtained in this way was mixed in a non-hydrolyzed system, the oily substance was a continuous phase. It is different from powdered oils and fats. Furthermore, oily substances contain an aqueous phase like margarine, and the water content is about 20% at most, so the water content in the resulting mixture is at most 15% or less. The mixture is used as a component of flour dough for manufacturing bakery products, either as it is or once passed through distribution and storage. The bakery products referred to in this invention are those that are puffed and baked using flour, water, and yeast or baking powder, and include not only various breads but also donuts, cakes, crepes, and the like. Any baking method can be used, such as a direct kneading method, a dough method, a no-time method, etc., but when adding soybean protein, the above-mentioned configuration in which soybean protein is mixed with an oily substance in advance should be satisfied. In addition to flour and water, the dough contains sugar, salt, milk solids, egg ingredients,
In addition, known raw materials such as conditioning agents such as calcium stearoyl lactitate, vitamins such as vitamin B 1 B 2 and niacin, iron, minerals, etc. can be added, and in addition to the oily substance that is mixed with soybean protein in advance. It is also possible to add similar oily substances at a separate stage. A composition in which soybean protein and an oily substance are mixed in advance,
The proportion of wheat flour dough can be used in the range of 5 to 15%, calculated as the weight ratio of isolated soy protein powder/flour.
The preferred percentage is in the range 8-11%. This invention will be explained below with reference to Examples. Example 1 Bread was produced by changing the method of adding soybean protein, and control bread without soybean protein was also produced. That is, for each test plot, 80% of strong flour
2.5 parts of yeast, 0.1 part of yeast food, 0.2 parts of emulsifier, and 48 parts of water using a cake mixer (26.5°C), fermented for 4 hours (28°C) to prepare a medium dough, and then mixed with strong wheat flour. Add 20 parts, 50 parts of caster sugar, 2 parts of table salt, and the additives listed in Table 1 to the middle dough, and after kneading, 15 minutes on the floor, and 20 minutes on the bench,
Round and divide, then put into a Pullman mold, ferment in a roasting oven at 40℃ for the time shown in Table 1, and finally
It was fired at 180°C for 35 minutes. The condition of the dough during rolling and the evaluation of the product bread are also shown in the same table. The cross section of the product slice is shown in the reference photo. In addition, the rolled and divided dough was placed in a one-loaf mold separately, fermented in a roasting oven for the time shown in Table 2, then baked at 180℃ for 25 minutes, and the height and specific volume were measured. The results shown in Table 2 were obtained.
