- the physical property values of (A) and (B) are physical property values obtained for the inside of the puffed food.
- the inside of the puffed food is the part other than the surface of the puffed food and the part other than the hardened surface layer (in the case of bread, the part called the crust).
- each physical property value can be measured by using a cube having a side of 2 cm cut out from the central part including the center of the puffed food as a test specimen.
- OM is a food property evaluation system (evaluation device, evaluation method) developed by the applicant.
- the OM device is devised to improve the reproducibility of changes in food properties in the oral cavity by simulating the sliding motion of the tongue or teeth in the oral cavity.
- the physical properties of the food can be evaluated by obtaining the time change of the product and the time change of the torque.
- the eating process of puffed foods including bread consists of a chewing process and a swallowing process, and the chewing process in the oral cavity can be divided into four stages: the first mastication stage, the early mastication stage, the middle mastication stage, and the late mastication stage. can.
- the first mastication stage is a stage in which the food is first chewed with teeth, and in terms of texture, it is a stage in which "hardness of chewing" is felt.
- the first period of mastication corresponds to the first half of the period from the start of mastication in the oral cavity to the swallowing of the food (referred to as the "mastication period") divided into three periods.
- the first stage of mastication is a stage in which air bubbles in the puffed food are destroyed by mastication and a feeling of compression (increase in hardness) is felt.
- the middle period of mastication is a period in which the number of times of mastication from the start of mastication corresponds to 1/3 to 2/3 of the total number of times of mastication.
- the bolus compressed in the oral cavity is mixed with saliva by mastication, resulting in increased adhesiveness and a “sticky feeling” (when saliva and food are mixed, the mouth feels sticky). It is a stage where you can feel the stickiness you feel inside.
- the latter period of mastication is a period in which the number of times of mastication from the start of mastication corresponds to 2/3 to 3/3 of the total number of times of mastication.
- the bolus absorbs saliva and increases its water content, resulting in a decrease in hardness and adhesiveness. This is the stage where you can feel the ease of loosening the bolus.
- the "hardness of chewing" in the "first chewing period” stage can be evaluated by obtaining the impulse value of the first bite using the OM device.
- the "sticky feeling" in the "mid-mastication” stage is obtained by calculating the average value of the torque measured in the OM device from 40 seconds to 50 seconds after the start of operation of the OM device. can be evaluated by In the present disclosure, this is referred to as the "torque average value in the middle period of mastication".
- the average value of torque in the middle of mastication thus obtained corresponds to the sensory resistance in the oral cavity and corresponds to the viscosity of the test food (bolus) mixed with saliva.
- the torque average value in the middle stage of mastication can be understood as the "stickiness" of the bolus in which the food and saliva are mixed in the oral cavity.
- the OM device is designed so that simulated saliva can be added at a predetermined flow rate into the space between the upper jig and the lower jig from the simulated saliva supply unit through the inflow tube. Simulated saliva is added in By adjusting the flow rate of simulated saliva addition, the amount of simulated saliva at 45 seconds, which is the middle point between 40 and 50 seconds after the start of operation corresponding to the middle stage of mastication, was adjusted to 100 parts by mass of the test food used. The ratio can be set to 50 parts by mass.
- the “pseudo saliva” a 0.02% by mass aqueous solution of xanthan gum that approximates the flow characteristics of saliva is used.
- the ⁇ ease of loosening of the bolus'' in the ⁇ late mastication'' stage was evaluated by adding simulated saliva to the test food and mixing it with an automatic mortar. It is possible to evaluate by preparing a test sample simulating a bolus in the late stage of mastication, subjecting it to a texture test, and determining (1) hardness (load) and (2) adhesiveness.
- the latter stage of mastication corresponds to a stage in which the hardness and adhesiveness of the food decrease due to an increase in water content as the food continues to be masticated in a bolus state in which saliva has been absorbed.
- the test sample (simulated sample of the bolus at the late stage of mastication) subjected to the texture test was placed under room temperature (25 ° C.) conditions at a rate of 100 parts by mass with respect to 100 parts by mass of the test food. can be prepared by stirring for 30 seconds at a stirring speed of 20 times/30 seconds.
- Water is used as a "simulated saliva" in this texture test.
- the water may be ordinary water (drinking water that meets the water quality standards based on Article 4 of the Water Supply Law [Law No. 177 of June 15, 1957: Ministry of Health, Labor and Welfare of Japan]). The test method and conditions for the texture test will be described later.
- the texture test is defined as "a system that measures a sample containing simulated saliva to evaluate the ease of loosening of the bolus in the late mastication period" and "a system in which simulated saliva is added to evaluate the hardness of chewing.”
- texture test with simulated saliva
- texture test without simulated saliva

- Delayed elastic modulus (elastic modulus E1 [Pa]): elastic modulus of the Voigt body
- the delayed elastic modulus indicates the elastic modulus of the spring among the elastic moduli of the Voigt body in the delayed deformation portion. Delayed deformation means that the spring tries to deform instantaneously against the load, but is controlled by the dashpot and deforms with a delay (the spring and the dashpot are parallel). It corresponds to the value obtained by dividing the stress by the strain.

It corresponds to the value obtained by multiplying the elastic modulus by the delay time. From these delayed elastic modulus and delayed viscous modulus, it is possible to evaluate the delayed deformation part, that is, both the elastic property that deforms immediately when force is applied and the viscous property that deforms with a delay as a state over time. Therefore, it can be interpreted as the elasticity and viscosity (the texture when the food starts to break down after being chewed) when the food is chewed with teeth and force is applied.

- each test food was cut into 5 cm long and 1 cm thick pieces (1 test piece) after cutting off the ears on all four sides, and immediately subjected to the sensory test.
- the sensory evaluation was carried out by masticating the test food with teeth on the eating surface. Moreover, the amount for one mouthful was set so that one test piece could be eaten in two mouthfuls. First, the panel was asked to eat the test food, and the number of times of chewing required to swallow a mouthful was counted. Next, the "hardness of chewing" when the same test food is chewed again with teeth on the eating surface (first mastication period), and the total number of chewing times between chewing in the mouth and swallowing , the "sticky feeling” that sticks to the teeth and oral cavity during the period from 1/3 to 2/3 of the number of chewing (mid-mastication), and swallowing from 2/3 of the total number of chewing. The following method was used to evaluate the "ease of loosening of the bolus" during the period (late stage of mastication) until (3/3 of the total number of mastications).
- the reference product (2) After cutting off the four edges of the reference product (1), it was cut into pieces of 5 cm in length and width and 1 cm in thickness, baked in an oven toaster for 3 minutes, and returned to room temperature.
- the scoring method was carried out based on the description on pages 186 to 187 of "Sensory Evaluator Text" (edited by Japan Sensory Evaluation Society: 2009, published by Kenpakusha).
- the sensory evaluation in order to unify the internal standards of each panel, several puffed foods were used in advance, and the sensory evaluation test was performed by the above method. By combining these feelings (trial evaluation/calibration), each panel has a common understanding. This evaluation was performed blind so as not to distinguish between test foods.
- Examples 1 to 3 and Comparative Examples 1 and 4 were carried out by three panelists, and the average values and standard deviations are shown. Other examples and comparative examples were carried out by one of the three panelists who was an expert in the sensory evaluation test and who represented the panel, and the results are shown below. From these results, the bread-like food of the example had a chewy hardness and a soft texture similar to that of wheat bread. On the other hand, the sensation of sticking (sticky) to the teeth and the oral cavity during the middle stage of mastication in the oral cavity was significantly less than that of wheat bread, and the loosening of the bolus in the latter stage of mastication in the oral cavity was significantly less. Ease was significantly higher than wheat bread.
