Description

Technical Field

[0001] The invention relates to the technical field of salt consumption evaluation, and in particular to an edible salt test paper evaluation system. Background Art

[0002] With the progress of society and economic development, people's living standards and quality of life are also constantly improving. The demand for necessities such as edible salt has developed from satisfying usage needs to requiring a variety of nutritional salts. As a necessity in life, the safety of edible salt is extremely important and is related to the health and life of every family and consumer.

[0003] Everyone has a different taste for salt. Some people prefer light salt, while others prefer heavy salt. Especially for people with medium salt taste, epidemiological and clinical studies have shown that excessive intake of salt (sodium chloride) can increase the risk of stroke, cardiovascular and cerebrovascular diseases. However, it is difficult to accurately assess salt intake, and there is an urgent need to develop and validate innovative dietary assessment methods.

[0004] At present, in the prior art, the main methods for evaluating salt intake are questionnaire method and detection method, that is, using analytical instruments to detect the concentration of sodium and potassium ions in food and urine. Among them, the excretion of sodium and potassium in 24h urine is considered to be the gold standard for evaluating salt intake. However, it is difficult to obtain all the urine of an individual for 24h in an evaluation survey with a large number of research subjects. Instead, the morning urine of each participant is collected, and the sodium and potassium content is determined by atomic absorption spectrophotometry or ion chromatography. Combined with parameters such as creatinine concentration, individual weight, height and age, the Kawasaki formula is finally used to correct the excretion of 24 urinary sodium and potassium.

[0005] The above methods in the prior art mainly focus on the evaluation of the salt intake of the population, rather than the evaluation of the salt tolerance and degree of the population. It is not convenient to evaluate and screen out people with different levels of salt tolerance and degree. In addition, the sampling and analysis costs of the above existing methods are relatively high, and the evaluation and calculation results are easily affected by insufficient or excessive sample collection.

[0006] Therefore, the present invention aims to provide a salt test paper evaluation system to solve the above-mentioned problems, evaluate the amount and degree of salt tolerance, and facilitate statistical screening of different groups of people in the country with different amounts and degrees of salt tolerance.

The evaluation test paper board 1 is provided with multiple salinity tolerance value identification areas 6 corresponding to the multiple salinity tolerance evaluation test paper blocks 5 one by one.

[0043] The salt tolerance test strip 5 is used to test the salt tolerance corresponding to the taste of different people.

[0044] The salinity tolerance value identification area 6 is used to identify the salinity tolerance value of an individual in the population measured by the salinity tolerance evaluation test paper block 5 .

[0045] The evaluation and analysis system is used to record, count and analyze the salt tolerance values ​​corresponding to the taste of each person in the population measured by the salt tolerance evaluation test strip 5, classify the salt tolerance of the population, and distinguish between people with high salt tolerance, people with medium salt tolerance and people with low salt tolerance.

[0046] The evaluation equipment is used to collect the salinity tolerance of individuals in the population measured by the salinity tolerance evaluation test paper block 5 and the salinity tolerance value marked in the salinity tolerance value identification area 6, and match the evaluation and analysis system to perform recording, statistics and analysis.

[0060] In this embodiment, an extension strip 20 is integrally formed on one side edge of the evaluation paper strip 1. On the one hand, it is convenient to mark the side of the evaluation paper strip 1 opposite to the extension strip 20 as the head end inserted into the strip-shaped slot 8. On the other hand, it is convenient to take the evaluation paper strip 1 out of the strip-shaped slot 8.

[0061] The specific implementation process of this implementation plan is as follows:

[0062] The salt tolerance of the person being tested is tested by placing the salt tolerance test paper block 5 in the salinity test paper strip pasting area designed on the test paper board 1 starting from the lowest salinity value, that is, the salt tolerance test paper block 5 is given to the person being tested to lick. When the person being tested feels that the salinity of the salt tolerance test paper block 5 is suitable for his or her taste buds, the salinity value of the salt tolerance test paper block 5 is marked in the salt tolerance value marking area 6 corresponding to the salt tolerance test paper block 5 on the test paper board 1, which is the salt tolerance value of the salt tolerance test paper block 5. The salt tolerance value of the person being tested; when the person being tested licks the salt tolerance assessment test paper block 5 with his mouth and his taste buds feel that the salinity of the salt tolerance assessment test paper block 5 is not suitable for his taste buds, the test paper blocks 5 of the next gradient are replaced in sequence for testing until the person being tested feels that the salinity of the salt tolerance assessment test paper block 5 is suitable for his taste buds, and the salinity value of the salt tolerance assessment test paper block 5 is marked in the corresponding salt tolerance value identification area 6, which is the salt tolerance value of the person being tested. Then, the tested evaluation paper board 1 is placed into the strip slot 8 of the testing equipment, and the test data information (salinity value marked in the salinity tolerance value identification area 6) of the evaluation paper board 1 is recorded, counted and analyzed through the testing equipment and the evaluation and analysis system, and the salinity tolerance of the tested persons is classified to screen them out as people with high salinity tolerance, people with medium salinity tolerance or people with low salinity tolerance.
