Description

Material odor test apparatus and material odor test method used therefor

The present invention relates to a material odor test apparatus for measuring a diffuse odor of a sample such as a food and a material odor test method used therefor.

When a human obstructs food, an aroma component is released from the food in the oral cavity, and it reaches the nasal cavity through expiratory airflow, causing olfactory stimulation. Moreover, the obstructive property is human.
Therefore, an inhibition model device (material odor test device) capable of measuring the emitted odor during inhibition after grasping such inhibition characteristics is disclosed (for example, see Non-Patent Document 1). . In such an obstruction model device, the strength test of the target sample is performed in a cylindrical sealed container made of a transparent material such as glass or acrylic, and then a Tenax (registered trademark) tube is placed in the sealed container. It is connected or connected to a PTR-MS or the like and purged with an inert gas (for example, nitrogen gas) or clean air to measure the diffuse odor during the simulated inhibition.

On the other hand, as a test apparatus, a material test apparatus that performs a three-point bending strength test is disclosed (for example, see Patent Document 1). FIG. 8 is a schematic configuration diagram showing a material testing apparatus for performing a three-point bending strength test. One direction horizontal to the ground is defined as an X direction, a direction horizontal to the ground and perpendicular to the X direction is defined as a Y direction, and a direction perpendicular to the X direction and the Y direction is defined as a Z direction.
The material test apparatus 101 includes a machine base 7, a casing 14 that rotatably supports two

screw shafts

5 and 13 whose vertical direction (Z direction) is a rotation axis, and a central portion on the upper surface of the machine base 7. A support base 112 provided; a crosshead 8 that can be screwed into the

screw shafts

5 and 13 and moved vertically with respect to the machine base 7 as the

screw shafts

5 and 13 rotate; A load cell 111 fixed at the center of the lower surface and an arithmetic control unit 103 that performs control and arithmetic processing are provided.

Inside the machine base 7, a motor 4 controlled by a control signal from the arithmetic control unit 103, a belt 61 that transmits the rotational force from the motor 4 to the

screw shafts

5 and 13, and an interlocking pulley 62 are connected. A gear mechanism 6 is arranged. Thereby, when the motor 4 rotates, the two

screw shafts

5 and 13 rotate, and the crosshead 8 is moved in the vertical direction with respect to the machine base 7.

Two plate-like supports 130 that are parallel to each other are attached to the upper surface of the support 112 so as to be aligned in the X direction. On the other hand, one plunger (pressing part) 120 is attached to the lower surface of the load cell 111. With such a support 130 and the plunger 120, the plate-shaped test piece S is placed with the upper ends of the two supports 130 as a fulcrum, and the load W is set with the lower end of the plunger 120 as a load point. The test piece S is loaded on a predetermined part.

Using such a material test apparatus 101, the moment when a crack occurs in the test piece S is detected.

When 0.90 minutes elapses after the measurement start signal is input, the switching mechanism 63 is switched to connect to the discharge flow path 61d, and from the inert gas supply source 72 through the sample back 40 to the discharge flow path 61d in this order. A certain amount of gas is circulated. At the same time, the pressing body 21 starts to descend at a constant speed (for example, 100 mm / min), descends at a constant speed for 0.15 minutes, and then rises at a constant speed for 0.15 minutes.
Then, when 1.20 minutes have passed since the measurement start signal was input, the switching mechanism 63 is switched and connected to the discharge flow path 61e, and the inert gas supply source 72 passes through the sample bag 40 and the discharge flow path 61e. A certain amount of gas is circulated in order. At the same time, the pressing body 21 starts to descend at a constant speed (for example, 100 mm / min), descends at a constant speed for 0.15 minutes, and then rises at a constant speed for 0.15 minutes.
Thereafter, that is, when 1.50 minutes have passed since the measurement start signal was input, the operation of the suction pump 70 is stopped.

Here, a material odor inspection method for measuring the diffuse odor of the sample S using the material odor test apparatus 1 according to the embodiment of the present invention will be described.

Specifically, the measurer or the like inputs a measurement start signal to the arithmetic control unit 3 to start measurement. When the measurement start signal is input, the calculation control unit 3 starts to lower the pressing body 21 at a constant speed (for example, 100 mm / min), lowers the pressing body 21 at a constant speed for 0.15 minutes, and then decreases to 0.15 at a constant speed. The raising is repeated several times (for example, 4 times) for a minute. Further, by operating the suction pump 70 and switching the switching mechanism 63 at a predetermined timing, the suction pump 70 is connected to one discharge flow path 61 selected from among the five discharge flow paths 61a to 61e. As a result, the components contained in the gas are adsorbed to the adsorbents in the test tubes 62a to 62e at the respective timings.

The component adsorbed on is introduced into GCMS. Thereby, the diffuse odor of the sample S at the time of the 0th press is measured.
Next, one test tube 62b is connected to the GCMS, and the component adsorbed by the adsorbent in the test tube 62b is introduced into the GCMS. Thereby, the diffuse odor of the sample S at the time of the 1st press is measured.
Next, one test tube 62c is connected to the GCMS, and the component adsorbed by the adsorbent in the test tube 62c is introduced into the GCMS. Thereby, the diffused odor of the sample S at the time of the 2nd press is measured.
Next, one test tube 62d is connected to the GCMS, and the component adsorbed by the adsorbent in the test tube 62d is introduced into the GCMS. Thereby, the diffuse odor of the sample S at the time of the 3rd press is measured.
Next, one test tube 62e is connected to the GCMS, and the component adsorbed by the adsorbent in the test tube 62e is introduced into the GCMS. Thereby, the diffused odor of the sample S at the time of the 4th press is measured.
