Recently, some media released a "13 mustard mustard test ", which reported the nitrite , sweetener and lead content of 13 mustard mustard tubers commonly found in the market , and then based on this test , it gave the "X type mustard mustard safety Conclusions such as “higher”
.
.
The media from time to time to see such a report, it always causes a lot of other media and consumer attention
.
However, it is meaningless to choose mustard tuber based on such test results
.
The only conclusion that can be drawn from this "13 mustard tuber test" is that there is no need to consider the nitrite, sweetener, and lead content of these mustard tubers.
The data of different brands is meaningless

.
This question requires a bit of professional logic.
Here are a few points:
Here are a few points:
1.
Nitrite
Nitrite
The nitrite in mustard tuber is not artificially added, but is naturally produced during the fermentation process
.
Its content is relatively volatile, and the test value of a sample may not even represent the content of that batch, let alone the content of that brand
.
In other words, if you buy another product of the same brand and the same model for testing, the detection value may be completely different
.

.
In other words, if you buy another product of the same brand and the same model for testing, the detection value may be completely different
.
In this test, the value of the sample with the highest test value is 3.
6 mg/kg, while the national standard limit is 20 mg/kg
.
The test results of all samples are far below the national standard, so there is no need to entangle
.

2.
Sweetener
Sweetener
The sweetener is artificially added and the content is controllable
.
.
As long as the requirements of the national standard are met, there is no need to tangle at all
.
Taking "there are studies showing that a large amount of a certain sweetener may cause XX symptoms" is to use the logic of "prefer to believable" to deduce scientific experiments to cause consumers to be uneasy.
It does not mean to be responsible for consumers Attitude

.
As a mass media, what should be conveyed is: as long as the pectin is used in compliance with the standards, there is no need to worry about health effects
.
.
In that report, the content of different sweeteners in the same product was added together to get a "total content"
.
This is a very "civilian" operation
.
Different types of sweeteners have different sweetness levels, different usage limits, and possible effects on health when "large intake" are different.
Adding the contents is a completely layman's approach

Adding the contents is a completely layman's approach
.
In these mustard tubers, the amount of various sweeteners is below the maximum use limit
.
In the national standard, there is a provision to restrict the mixed use of multiple food additives-"When the food additives with the same function (same color and coloring agent, preservatives, antioxidants) are mixed and used, their respective amounts account for the largest amount of use.
The sum of the proportions should not exceed 1.
" In the specific description in parentheses, only the same coloring agents, preservatives and antioxidants are listed, and there is no "etc", which means that other food additives with the same function—— Such as sweeteners, mixed use is not subject to this restriction

.
In fact, the sweeteners used in these mustard pickles do not exceed 1 in "the sum of their respective amounts in their maximum consumption"
.
.
In short, the use of sweeteners in these 13 mustard pickles does not need to be entangled at all, and there is no need to consider who is high and who is low
.
.
3.
Lead
Lead
The situation of lead content is similar to that of nitrite
.
It mainly depends on the soil condition of the raw material producing area, and its volatility is also relatively large
.
The test value of a sample only shows the lead content in that batch of raw materials, and does not represent the lead content level of other batches of that product at all
.

.
Among the 13 samples, the highest lead content is 0.
237 mg/kg, which is much lower than the 1.
0 mg/kg limit of the national standard, so you don't need to care at all

In fact, the media also emphasized in the report that "the test results and the brands mentioned in this report are only responsible for the test samples, and do not represent the quality status of the same batch or other types of products
.
" However, for readers who read this report, how many people can notice and understand this explanation correctly? This statement is actually equivalent to a "disclaimer" to deal with the accusations of the brand

If you are really responsible for consumers, then the report of this test result only needs one sentence:
Purchase a pack of mustard tuber from the following 13 brands (brands A, B, C.
.
.
) and test for nitrite, sweetener, and lead.
All of them are fully qualified

When talking about this matter, Teacher Fan Zhihong posted a comment, which is also worth sharing:
When choosing pickled mustard, there is no need to care about such "tests

" Through formal channels, you can choose the taste you like according to the price you can accept
