Embodiment 1
[0029] Such as figure 1 As shown, the present invention provides a production process of edible test paper for measuring psychological stress. Pullulan (α-1,4-; α-1,6-glucan) and polymer hydroxypropylmethyl Cellulose (HPMC) was mixed and used at a weight ratio of 1:11.5 to prepare a colloid with a final polymer concentration of 3.25% wt / vol.
[0030] Concrete preparation steps are as follows:
[0031] 1) First, add 2.99g of HPMC powder to a solution of 100mL of distilled water at 75 to 80°C and stir rapidly, then add 0.26g of pullulanpowder, cool the mixture to room temperature, and then add quinine hydrochloride (Quininehydrochloride, according to Concentration requirements, the specific addition amount can be calculated, the maximum concentration is 2.5%wt / vol).
[0032] 2) The surface of the container is washed with ethanol with a concentration of 95% by mass, dried and wiped clean with a paper towel.
[0033] 3) Spread 2.34 mL of the solution evenly on a cell culture d...
Embodiment 2
[0037] Such as figure 2 As shown, the process of using the test paper of the present invention to carry out the psychological stress test is also provided, and the specific measurement steps are as follows:
[0038] 1) Ask the subjects to rinse their mouth twice;
[0039] 2) Put the test paper of the initial concentration on the tip of the subject's tongue, and ask the subject to touch the chamber with the tip of the tongue;
[0040] 3) After 5 seconds, the subject is asked to answer the taste and rinse his mouth;
[0041] 4) Select a test paper with a higher or lower concentration according to the reported results, and repeat the previous step.
[0042] 5) When the subject can perceive the current concentration, but cannot perceive the concentration one level lower than the current concentration, the measurement is ended;
[0043] 6) The threshold value can be determined multiple times through repeated testing, and the average value can be taken.
[0044] 7) The testees ...

Abstract
The invention provides edible test paper for measuring psychological stress. The edible test paper comprises a layer of a test film, wherein the test film is composed of amylopectin, polymer hydroxypropyl methyl cellulose and quininehydrochloride in a mass ratio of (0.2-0.3): (2.5-3.5): (0-2.5). The invention also provides a preparation method of the edible test paper for measuring psychologicalstress. The invention also provides a method for testing psychological stress by adopting the test paper. According to the invention, the edible quinine test paper is used for determining the bitter tasteperception threshold value of a testee, and the bitter tasteperception threshold value of quinine is positively correlated with the degree of recent psychological stress.
Description
technical field [0001] The invention belongs to the field of human life and relates to a psychological measurement method, in particular to an edible test paper for measuring psychological stress and a preparation method thereof. Background technique [0002] Psychological stress is a human state of mind that is of concern to many industries and application areas. Some fields, such as aviation, military and other fields involving dangerous operations, pay special attention to people's psychological stress state, and need objective and convenient measurement methods. [0003] At present, the measurement of psychological stress mainly relies on the "perceived stress scale". The questionnaire investigates the level of psychological stress in the past month through 10 questions. However, this questionnaire is a subjective questionnaire, which is influenced by subjective intention and social approval, so it is not suitable for a test of great importance. [0004] At present, t...
