Description

Hard biscuit and manufacturing method thereof

The present invention relates to a hard biscuit and a manufacturing method thereof.

Hard biscuit is a baked confectionery that uses wheat flour as a main ingredient, refrains from sugar and oil, and adds a lot of water to knead it over time. In general, gluten is formed by kneading and a firm dough is finished, and this is thinly molded and baked. It is characterized by having a chewy texture compared to soft and moist soft biscuits, but in recent years, it tends to be preferred to have a crispy texture and excellent mouth melting.

A method for increasing the fat content is conceivable as a method for imparting a light texture and a good meltability to hard biscuits. However, in general, increasing the fat content softens the biscuit dough and makes it difficult to form a sheet, or the mechanical suitability decreases due to the occurrence of stickiness, so there is a limit to increasing the fat content and a sufficient effect is obtained. Was difficult. There is also a problem in that the volume and strength after firing are reduced due to insufficient gluten formation. A method of increasing the fat content by applying spray oil to the baked confectionery after baking has been proposed (Patent Document 1), but a special facility is required, and the conventional baked confectionery line has poor feasibility.

Addition of an emulsifier can be mentioned as a method for improving the texture of hard biscuits without impairing the moldability of the dough and the product strength. Among them, it is known that the addition of a sucrose fatty acid ester having a high HLB is effective (Patent Document 2). By using sucrose fatty acid ester, dough extensibility and mechanical resistance can be improved, and the volume after baking can be improved to give a light and crisp texture. The baked confectionery added with sucrose fatty acid ester has a small inner layer opening and is rich in uniform bubbles, however, saliva is absorbed into the uniform bubbles when eating, resulting in a powdery taste and poor melting in the mouth. . In addition, there is a problem that stickiness in the oral cavity increases in proportion to the amount added. Furthermore, it cannot be said that the taste of the emulsifier itself is good, and the adverse effect on the original flavor of the baked confectionery cannot be ignored.

In addition, the following are disclosed as techniques for improving the texture of baked confectionery using emulsifiers, emulsified oils, and the like.

Patent Document 3 is obtained by emulsifying an oil-in-water type using edible fats and oils, carbohydrates, and water as main ingredients and adding an emulsifier selected from glycerin fatty acid ester, polyglycerin fatty acid ester, sucrose fatty acid ester or propylene glycol fatty acid ester. By adding a baked confectionery modifying agent, it is said that it can provide a baked confectionery that is well melted in the mouth and excellent in light feeling. In addition, Patent Document 4 discloses a soft food that is crispy by adding a confectionery or bakery quality improver whose constituent fatty acids of polyglycerin fatty acid ester having an HLB of 8 or more is myristic acid or oleic acid to baked confectionery. It is said that the mouth melts better and the flavor is improved. However, the effect of these techniques is largely due to the emulsifier used, and the dissatisfaction with conventional emulsifiers cannot be resolved. At present, satisfactory results are not yet obtained in terms of crispness, melting in the mouth, and strength.

Sodium stearoyl lactate is known as an anionic emulsifier. It has an effect of plasticizing the gluten network and an effect of stabilizing bubbles, and also has an effect of preventing the aging of the starch of the product, so it is used for bread, American dogs, cakes and the like (Patent Documents 5 to 8). However, no proposal has been made to use sodium stearoyl lactate for the purpose of improving the texture of hard biscuits.

Item 9. For flour, fats and oils, sugars, organic acid monoglyceride, and stearoyl sodium lactate, the total amount of organic acid monoglyceride and sodium stearoyl lactate is 0.1 to 0.9 parts by weight with respect to 100 parts by weight of flour. Organic acid monoglyceride and stearoyl lactic acid Adding and mixing water to the raw material blended so that the mass ratio of sodium is organic acid monoglyceride / sodium stearoyl lactate = 1/9 to 3/7, molding the resulting dough and baking A method for producing a hard biscuit characterized by the above.
Item 10. Item 10. The hard article according to Item 9, which includes a step of forming the dough into a noodle shape or a rod shape and having a cross-sectional area after baking of 8.0 to 80.0 mm ² and baking after immersion in alkaline water, and the hard biscuit is a pretzel Biscuits manufacturing method.

According to the present invention, by using sodium stearoyl lactate and organic acid monoglyceride as an emulsifier, it is possible to obtain a hard biscuit having a crispy texture and a good meltability without reducing the strength. Further, by using active gluten and hemicellulase in combination, it was possible to obtain a hard biscuit having a good volume increase during baking and excellent crispy feeling.

ステ Sodium stearoyl lactate works to plasticize the gluten network and improve the extensibility of the fabric. In hard biscuits, since the bubbles in the dough are maintained in a relatively rough state, it has been found that this affects the inner layer after baking and gives a good mouth melt without powderiness. However, the addition of sodium stearoyl sodium lactate is not suitable for a hard biscuit for forming a thin sheet because the elasticity of the fabric is extremely lowered and the extensibility becomes excessive. Further, the volume and crispness during firing were not sufficient. As a result of intensive studies, it was found that by adding an appropriate amount of an organic acid monoglyceride, it was possible to compensate for the decrease in elasticity, which is a drawback of sodium stearoyl lactate, and to improve sheet molding suitability and volume feeling. Further, when active gluten and hemicellulase are used in combination, the volume feeling can be increased and a more excellent crisp feeling can be imparted. The hard biscuits thus obtained had a powdery texture, stickiness during chewing, improved adhesion to teeth, and good melting in the mouth, as is the case with conventional emulsifiers.

According to the production method of the present invention, it is possible to obtain a hard biscuits with good flavor while improving the texture. In particular, it is very good in that there is no powderiness and the fragrance is emphasized.

The dough prepared by blending in the present invention is good in both elasticity and extensibility, and is said to bring about improvement in workability and reduction in loss rate in that it is easy to form a sheet without stickiness and into a noodle or rod shape. Has an effect.

The hard biscuits after baking have a moderate texture while having a light texture. Since there is no reduction in strength that is common in the prior art, stable production can be achieved with existing equipment. In addition, defects such as cracking and chipping are not likely to occur even in processes such as cream sand, it can withstand impact during transportation, and cracking and chipping do not cause problems, and it has high palatability and commercial value. It is also possible to produce a composite confectionery stably.
