A. First embodiment:
FIG. 1 is an explanatory diagram illustrating a configuration of a measuring device 10 that executes a method for measuring a sesame leaching oil amount. The XYZ axis of FIG. 1 has an X axis, a Y axis, and a Z axis as three spatial axes orthogonal to each other. The XYZ axes in FIG. 1 correspond to the XYZ axes in other figures. The measuring device 10 is a device that measures the amount of leached oil, which is oil that oozes from sesame by a process such as rubbing. The measurement device 10 includes a moisture content sensor 20 and a container 30.

The water content sensor 20 detects the water content based on the electrical characteristics. The moisture content sensor 20 is a TDT soil moisture sensor (model: CACC-SEN-SDI, manufactured by Climatec Corporation). Items that can be measured using the TDT soil moisture sensor include the following six items.
・ Relative permittivity ・ Waveform maximum rise value (mV / ns)
・ Maximum rising amplitude (mV)
・ Propagation time at the time of maximum rise (ps)
・ Waveform propagation time (ps)
・ Correction propagation time (ps)

  The moisture content sensor 20 includes a probe portion 25 and a head portion 27. The probe part 25 is a part of a probe for detecting a water content. The head portion 27 is a substantially rectangular parallelepiped portion for measuring a temperature. The moisture content measured by the probe portion 25 is corrected by the temperature value measured by the head portion 27.

  The container 30 has a size capable of storing the probe portion 25 and the head portion 27 of the moisture content sensor 20, and is formed of a material having an insulating property. In the present embodiment, the material of the container 30 is an acrylic resin. In another embodiment, the material of the container 30 may be any material as long as the material has an insulating property. The container 30 has a lid 32 and a main body 34.

  The lid 32 has a shape that fits into the opening of the main body 34. The main body 34 has a box shape with an opening on the + side in the Z-axis direction, and has a space in which the probe portion 25 and the head portion 27 can be stored inside. The size of the main body 34 is such that the length of the horizontal X1 is 7 cm, the length of the vertical Y1 is 21.6 cm, and the length of the height Z1 is 5 cm.

  On the side surface of the main body 34 on the + side in the Y-axis direction, there is formed a concave portion 36 that is recessed from the end surface on the + side in the Z-axis direction toward the − side in the Z-axis direction. When the probe portion 25 and the head portion 27 of the moisture content sensor 20 are disposed in the main body 34, the code portion 23 of the moisture content sensor 20 is placed in the concave portion 36.

  FIG. 2 is a process chart showing a method for measuring the amount of leached oil of sesame. The measurement method described with reference to FIG. First, the measurer performs a packing process of spreading sesame so that the bottom surface 38 (shown in FIG. 1) in the container 30 is covered (process P110). In the present embodiment, sesame is spread so as to have a height of about 2 cm from the bottom surface 38. Next, the measurer performs a sensor arranging step of arranging the probe portion 25 and the head portion 27 of the moisture content sensor 20 on the sesame laid on the bottom surface 38 (process P120).

  FIG. 3 is an explanatory diagram showing a state of the measuring device 10 after the process P120 has been completed. After the process P120, the probe portion 25 and the head portion 27 of the moisture content sensor 20 are placed on the sesame SE spread on the bottom surface 38.

  Next, the measurer supplies sesame to the container 30 so that the probe portion 25 and the head portion 27 disposed on the sesame SE are buried in the container 30, and supplies the probe portion 25 and the head portion to the container 30. A burying step for filling 27 is performed (step P130). Sesame used for burial is a sesame to be measured.

  FIG. 4 is an explanatory diagram showing a state of the measuring device 10 after the process P130 has been completed. After the process P130, the probe portion 25 and the head portion 27 are buried in the container 30 by the supplied sesame SE.

  After the burying step (step P130), the measurer performs a compression step of compressing the sesame supplied into the container 30 to bring the moisture sensor 20 into close contact with the sesame (step P140). At this time, the measurer presses the lid 32 in the negative direction along the Z-axis in a state where the lid 32 is fitted to the opening of the main body 34, thereby bringing the moisture sensor 20 into close contact with the sesame, and Reduce the sesame voids fed into the 30. At this time, the pressing force of the lid portion 32 is not such a force that new oil seeps out of the sesame but a force that the probe portion 25 and the head portion 27 are brought into close contact with the sesame. The close contact between the water content sensor 20 and the sesame and the reduction of the gap of the sesame reduce the measurement error by the water content sensor 20. By performing the compression step (step P140), the evaluation by the moisture content sensor 20 can be performed with high accuracy. In the present embodiment, the height of the sesame in the container 30 after being compressed by the lid 32 is approximately 4 cm from the bottom surface 38.

  FIG. 5 is an explanatory diagram showing a state of the measuring device 10 after the process P140 has been completed. After the process P140, the probe portion 25 and the head portion 27 are brought into close contact with sesame by the lid portion 32 pressed against the main body.

  After the compression step (step P140), the measurer performs a measurement step of causing the water content sensor 20 embedded in the container 30 to perform measurement (step P150). Through steps P110 to P150 shown in FIG. 2, by analyzing the items measured by the water content sensor 20, the amount of sesame leached oil is measured.

  FIG. 6 shows measurement results of sesame samples 1 to 4 measured by the measurement method of FIG. FIG. 6 also shows the results of oil red staining in addition to the above-described six items measured by the water content sensor 20 as the measurement results. The reason why the amount of sesame leached oil can be measured by analyzing the items measured by the water content sensor 20 will be described with reference to FIG.

  Sesame samples 1 to 4 are samples obtained by subjecting the same sesame to different treatments and changing the amount of sesame oil discharged. The different processing here refers to rubbing sesame, piercing sesame with a stick, chopping sesame with a cutter, and adjusting the frequency of the processing. It has been experimentally confirmed that by performing different treatments on the same sesame, the amount of oil discharged from the sesame varies. Sesame samples 1 to 4 have larger amounts of leached oil in the order of sesame sample 1, sesame sample 2, sesame sample 3, and sesame sample 4. In other words, among the sesame samples 1 to 4, the amount of oil discharged from the sesame sample 1 is the largest, and the amount of oil discharged from the sesame sample 4 is the smallest.

  The measurement results by oil red staining will be described. In the oil red dyeing, the sesame samples 1 to 4 were pressed using a creep meter to dye the discharged oil adhering to the filter paper. The pressing strength of the creep meter when pressing the sesame samples 1 to 4 against the filter paper is the same between the sesame samples. As shown in the item “oil red staining” in FIG. 6, from the measurement results by the oil red staining, the sesame samples 1 to 4 are in the order of sesame sample 1, sesame sample 2, sesame sample 3, and sesame sample 4, It was confirmed that the amount of leached oil was large.

In FIG. 6, the calculation result of the correlation coefficient indicating the degree of correlation between the measurement result by the oil red staining described above and the measurement result of the six items by the water content sensor 20 is indicated by the item “correlation coefficient with staining”. It is shown as From the calculation result of the correlation coefficient shown in FIG. 6, among the items measured by the moisture content sensor 20, strong positive correlation was obtained in five items except the waveform maximum rising value (mV / ns) among the following six items: It was confirmed that there was. Further, it was confirmed that the waveform maximum rising value (mV / ns) had a strong negative correlation. That is, it was confirmed that the amount of oil discharged from sesame can be accurately measured by the measurement method using the water content sensor 20 described with reference to FIG.
・ Relative permittivity ・ Maximum rising value of waveform (mV / ns)
・ Maximum rising amplitude (mV)
・ Propagation time at maximum rise (ps)
・ Waveform propagation time (ps)
・ Correction propagation time (ps)

  According to the measurement method described above, it is possible to easily and accurately evaluate the amount of oil discharged from sesame as compared to the measurement method in which oil red is stained using a sample in which oil is adhered by pressing sesame on filter paper. it can.

  By using such a measurement method, effects can be expected in the following situations. In other words, when evaluating the amount of sesame leaching oil produced in a factory, the conventional method using oil red dyeing is complicated in the process of performing the evaluation. Unless transported to the laboratory, the amount of bleeding oil could not be evaluated. Moreover, it is difficult for those who do not have much working experience in the laboratory to carry out oil red staining. However, in the measurement method of the present embodiment, since the processing at the time of the evaluation is simple, it is necessary to evaluate the amount of leached oil on the spot without transporting the sample drawn from the factory line to the laboratory. Can be. For this reason, the amount of leached oil of sesame being manufactured can be quickly known. In other words, the measuring method of the present embodiment has an application possibility that the amount of leached oil of sesame being produced can be measured in real time while producing sesame on a factory line. In addition, since the measurement method of the present embodiment is simpler than performing oil red staining, even those who do not have much working experience in the laboratory, evaluate the amount of sesame leached oil. be able to. Further, in the measurement method of the present embodiment, since a reagent such as an organic solvent used for oil red staining does not need to be used, labor required for processing such a reagent can be omitted.

  FIG. 7 shows the results of the sensory evaluation of sesame samples A to D. The correlation between the amount of oil discharged from sesame and the sensory evaluation will be described with reference to FIG. The sesame samples A to D are sesame products sold by four different companies. In FIG. 7, the amount of leached oil of the sesame samples A to D is shown in the item “oil red”.

  The sensory evaluation of the aroma and taste of the sesame samples A to D was performed by a score evaluation by 25 specialized panelists. The evaluation items of the sensory evaluation are evaluation items related to fragrance, evaluation items related to taste, and evaluation items related to comprehensive evaluation. The evaluation items relating to the fragrance are five items of “fragrance”, “sweet fragrance”, “blue odor”, “sulfur odor”, and “comprehensive fragrance evaluation”. Evaluation items relating to taste are four items of “sweetness”, “bitterness”, “astringency”, and “mellowness”. The evaluation item related to the comprehensive evaluation is one item of “Comprehensive evaluation of fragrance and taste”. The sesame samples A to D were evaluated by setting the score of each item to three points of the sesame sample B as a reference and selecting from the range of 1 to 5 points. Each value in FIG. 7 indicates an average value.

  The item “correlation coefficient with staining” in FIG. 7 is a correlation coefficient indicating the degree of correlation between the item “oil red” and each evaluation item. The item “correlation with the comprehensive evaluation of fragrance / taste” in FIG. 7 is a correlation coefficient indicating the degree of correlation between the evaluation item “global evaluation of fragrance / taste” and each of the other evaluation items. is there.

  According to the result of the item “correlation coefficient with dyeing” shown in FIG. 7, in the evaluation items “sweet fragrance”, “sweetness”, and “mellowness”, there is a strong positive correlation with the item “oil red”. confirmed. In addition, from the results of the item “correlation with comprehensive evaluation of fragrance and taste” shown in FIG. And a strong positive correlation. Therefore, the evaluation items “sweet fragrance”, “sweetness”, and “mellowness” are evaluation items that have a high correlation with the item “oil red” and contribute to raising the item “comprehensive evaluation of fragrance and taste”. I found it. That is, it was confirmed that the score of the item “Comprehensive evaluation of aroma and taste” tends to increase as the amount of sesame oil discharged increases.

  As described with reference to FIG. 7, by confirming the amount of oil discharged from sesame, it is possible to estimate whether the “comprehensive evaluation of aroma and taste” of the sesame is high or low. In the past, oil red dyeing was used to evaluate the amount of leached oil, so that the process of performing the evaluation was complicated. However, by using the measurement method described with reference to FIG. 2, it is possible to easily and accurately evaluate the amount of oil discharged from sesame and quickly know the evaluation of the amount of oil discharged from sesame.

B. Other embodiments:
In the measurement method described above, the measurer performed the burying step (step P130), then performed the compression step (step P140), and then performed the measurement step (step P150). However, the present invention is not limited to this. I can't. For example, after performing the burying step (step P130), the measurer may omit the compression step (step P140) and perform the measuring step (step P150). Such a measuring method is preferably used when the sesame used for the measurement is relatively heavy. This is because, in the case of relatively heavy sesame, it is highly possible to realize close contact between the moisture content sensor 20 and the sesame and reduction of the sesame gap without the need for the compression step (step P140).

  In the measurement method described above, the measurement device 10 including the moisture content sensor 20 and the container 30 is used, but the present invention is not limited to this. For example, the moisture sensor 20 for measuring the amount of oil discharged may use a moisture sensor different from the TDT soil moisture sensor. The container 30 is not limited to the shape described with reference to FIG. 1 and is formed of a material having an insulating property, and has a shape that can realize close contact between the moisture content sensor 20 and the sesame and elimination of voids in the sesame. As long as the container has any shape, any shape may be used.

  The present invention is not limited to the above-described embodiments, examples, and modified examples, and can be realized with various configurations without departing from the spirit thereof. For example, the technical features in the embodiments, examples, and modifications corresponding to the technical features in each embodiment described in the Summary of the Invention section are for solving some or all of the above-described problems, or In order to achieve some or all of the above-described effects, replacement and combination can be appropriately performed. If the technical features are not described as essential in this specification, they can be deleted as appropriate.
