Shenyang Bureau of quality supervision carried out chromatographic detection of plasticizers

affected by the plasticizer incident, the sales of beverages in some supermarkets in Shenyang fell

with the advent of summer, the weather is getting hotter and hotter. The beverage industry should have entered the peak sales season, but this year's beverage industry is somewhat chilly. Wave after wave, the haze of plasticizer has not subsided, but new quality problems have come one after another. On the 13th of this month, the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China (AQSIQ) reported the results of spot check on the product quality of tea drinks, carbonated drinks, fruit and vegetable juice drinks and plant protein drinks in 2011. A total of 349 products produced by 316 enterprises in 22 provinces were spot checked. It was found that 6 drinks, including Wahaha white grape juice drinks, were unqualified because the total number of colonies exceeded the standard

what is the business situation of the beverage industry? Can the plasticizer be inspected? What exactly is the total number of colonies? What harm will it bring to the human body after exceeding the standard? What is the current safety status of Shenyang beverage? With these questions, the newspaper went to the authoritative food inspection institutions in Shenyang, the National Center for quality supervision and inspection of processed food and additives, and the Food Safety Institute of Shenyang Institute of product quality supervision and inspection, to find experts to answer the meaning of total bacterial count and experience the whole process of beverage inspection, so as to open the "mystery" of Shenyang beverage inspection for readers

[survey]

beverage sales fell by 10-30%

in the face of the fact that beverage crises occur frequently, what is the current situation of the beverage industry? For this reason, I visited many supermarkets in Shenyang and found that this is the peak season for beverage sales, but this summer's beverage sales situation is difficult to be optimistic

in a large supermarket on Taiyuan street, rows of drinks were placed in the center of the store for sale. Ice green tea, ice black tea, oolong tea and fresh orange juice of some well-known brands were all reduced from 2.5 yuan to 2.4 yuan per bottle, and the price of varieties was mostly reduced by 1 to 20 cents

Ms. Liu, a promoter of a certain fruit juice beverage, told us that at this time last year, about 10 boxes could be sold every day, but this year only 6 boxes could be sold, a decrease of 10-30%. When asked why, she said: "recently, what plasticizers and additives, how can citizens' consumption enthusiasm be high?"

the same desolate scene was seen in the supermarket of a large shopping mall in the middle street. Mr. Wang, a citizen, told us, "in the past, we tried to form a batch of innovative achievements and typical use of supermarket beverage areas. We can buy whatever we want, but now we have to consider it."

[authoritative response]

Shenyang has the ability to test plasticizers

for the current business status of the beverage industry, plasticizers are the culprit

yesterday, we specially interviewed the Food Safety Institute of Shenyang Institute of product quality supervision and inspection

: does the food safety institute have the ability to inspect plasticizers

Liu ran (director of Food Safety Institute): of course, he has the ability to test plasticizers and promote the industrialization of this new biomaterial

: is this a routine test item

Liu ran: No

: is the inspection to be carried out for a long time

Liu ran: it depends on whether we have investigated and dealt with such illegal acts in China. If such acts are widespread, they will be detected

: what method is used to test plasticizer

Liu ran: use chromatography and other methods. However, at present, the relevant departments have not asked for testing

[Q & A]

the total number of colonies and the harm of exceeding the standard

in addition, regarding another incident in the beverage industry, Liu ran said that colonies refer to the growth products that can be recognized by the naked eye formed by the growth and reproduction of bacteria on solid culture medium, which are composed of tens of thousands of the same bacteria. If the total bacterial count exceeds the standard, people will suffer from intestinal diseases after eating. The total bacterial count is an important indicator to evaluate the degree of bacterial contamination of food

Liu ran said: "bacteria are the largest number of organisms in nature, which will naturally erode and pollute food. The total number of colonies is an indicator of the general health status of food. Food with an excessive total number of colonies indicates that it is polluted by microorganisms in the process of production, storage, transportation and sales, which reflects the degree of biological pollution of food. The more seriously the food is polluted, the more the total number of bacteria."

[testing industry regulations]

closed sampling testing needs to pass 24 passes

after submitting the application, he followed director Liu ran into the beverage inspection area

in the sample room, a manufacturer in Shenyang just sent a sample of 12 bottles of fruit juice drinks to be tested. Liu ran said, "according to the relevant regulations, in order to ensure the authenticity of the inspection items, the drinks can only be opened after they arrive at the inspection room, and it is absolutely not allowed to open them in advance. In addition, in order to facilitate the manufacturer's review of the results, we have to leave some spare samples, so at least 12 bottles of samples."

besides submission for inspection, sampling inspection is more important. According to Liu ran, beverage testing is frequent, with more than a dozen times a year. Moreover, they are conducted in strict confidentiality, and enterprises or supermarkets will not know the specific time of sampling inspection at all. In addition, there is another kind of risk monitoring, that is, sampling personnel go to major supermarkets and markets to buy samples for inspection. The purpose of these two inspection methods is to be fair and equitable, and to prevent enterprises from cheating consumers by falsifying and shoddy goods. For a bottle of seemingly ordinary beverage, the detection of various indicators is a very huge system project, involving at least 24 items

[various indicators]

[first pass] total arsenic ≤ 0.2mg/l. Total arsenic refers to the total amount of arsenic in inorganic and organic compounds. Arsenic poisoning is often referred to as acute arsenic poisoning. Epidemiological studies have shown that long-term exposure to arsenic can cause a variety of cancers. [Second close] lead ≤ 0.05mg/l. It is mainly harmful to the nerve, hematopoietic system and kidney. It damages the skeletal hematopoietic system, causing anemia, cerebral hypoxia, brain edema, and abnormal movement and sensation. [the third pass] copper ≤ 5mg/l. [the fourth pass] sulfur dioxide residue ≤ 10mg/kg. The main reason why the sulfur dioxide residue exceeds the standard is that the production enterprises want to extend the storage time of the products and increase the appearance beauty of the products. However, excessive intake of sulfur dioxide will accumulate in the body, seriously damage the health of gastrointestinal, liver and other organs, and cause dyspnea, diarrhea, vomiting and other symptoms. [the fifth pass] patulin ug/l ≤ 50. Only applicable to fruit juice and hawthorn juice drinks. [the sixth pass] benzoic acid g/kg ≤ 1.0. Benzoic acid added to food can inhibit the growth of microorganisms, prevent food from spoilage and prolong the shelf life, but it has little toxicity. Excessive preservatives will endanger the health of consumers. Excessive consumption of benzoic acid for a long time may lead to the imbalance of gastrointestinal function and blood pH, which will affect the liver and kidney of the human body, especially increase the burden on the liver, which is harmful to human health. Therefore, the national standard has made strict provisions on its use. [seventh pass] sorbic acid g/kg ≤ 0.5. [the eighth pass] saccharin sodium g/kg ≤ 0.15. [9th level] sodium cyclamate g/kg ≤ 0.65. In order to reduce production costs, many enterprises use sodium cyclamate instead of fresh fruit juice to artificially make "fruit juice sweet" in beverages. However, long-term consumption of foods with excessive sodium cyclamate may have adverse effects on human health. [the tenth level] acesulfame g/kg ≤ 0.3

[11th pass aluminum rope tensile testing machine is applicable to the high-precision testing of tensile, zigzag, contraction, peeling, tearing and other mechanical properties of various materials to the 16th pass] colorant testing. Lemon yellow g/kg ≤ 0.1. Sunset yellow g/kg ≤ 0.1. Carmine g/kg ≤ 0.05. Amaranth g/kg ≤ 0.05. Bright blue g/kg ≤ 0.02. Alluring red g/kg ≤ 0.1. [the seventeenth pass] the total number of colonies cfu/ml low-temperature reconstituted fruit juice ≤ 500, others ≤ 100. Exceeding the standard will cause intestinal diseases after eating. [the 18th pass] coliform mpn/100m low temperature recovered juice ≤ 30, others ≤ 3. [19th pass] mold cfu/ml ≤ 20. [20th level] yeast cfu/ml ≤ 20

[twenty first level] pathogenic bacteria detection. Salmonella, Shigella and Staphylococcus aureus shall not be detected. [level 22] commercial sterility shall meet the requirements of commercial sterility, and is only applicable to canned products produced by canning process. [twenty third pass] the original juice content enterprise has indicated the technical requirements, which are only applicable to orange, orange, orange juice and its beverages, hawthorn juice and other beverages. [24th level] label

[spot check results]

the qualified rate of Shenyang produced beverages was 100%

after the test, Liu ran told that the products submitted for inspection were all qualified products. So, what are the inspection results of the beverages produced by Shenyang manufacturers? On the official station of Shenyang Municipal Bureau of quality and technical supervision, it was found that Shenyang Municipal Bureau of quality and technical supervision conducted product quality supervision and spot check on beverage production enterprises within the jurisdiction of Shenyang from February 15, 2011 to March 7, 2011. 19 beverage production enterprises were supervised and spot checked, and 19 were qualified, with a qualification rate of 100%; The oxygen index of ABS in 33 batches of products was 18.2 times, 33 batches of qualified products, and the product qualification rate was 100%

[expert advice]

Liu ran gave us several suggestions on how to buy drinks:

1 Select products with QS (food production license) mark

2. When purchasing, pay attention to whether the product packaging marks are complete (product name, factory name, factory address, production date, shelf life, ex factory date, net content, executive standard, raw and auxiliary ingredients list, etc.)

3. When purchasing beverage products, consumers should go to supermarkets and shopping malls with large scale and perfect management

4. In hot summer, don't drink cheap drinks. Pay attention not to drink drinks with too low temperature and too high carbon dioxide content. Because it is easy to cause gastrointestinal discomfort
