Vitamins are a kind of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. They play an important role in human growth, metabolism and development. The GB14880-2012 "Standard for the Use of Food Nutrition fortifiers" stipulates the types and amounts of foods allowed to add B vitamins. GB 10765-2010 "Infant Formula", GB 10767-2010 "Formula for Larger Infants and Young Children", GB 10769-2010 "Cereal Supplementary Food for Infants" and GB 10770-2010 "Canned Supplementary Food for Infants" stipulate the allowable amounts of B vitamins in infant-related foods. According to GB 28050-2011 "General Principles for Nutrition Labeling of Prepackaged Foods", prepackaged foods using nutritional fortifiers should be marked with the content value of the nutritional component in the fortified food and its percentage of the nutrient reference value (NRV) in the nutritional composition table.

According to the national standard for vitamin testing, vitamin B12, folic acid, biotin, niacin and pantothenic acid are all tested by microbiological method as the preferred method and arbitration method. However, the problem has come. When it comes to vitamin testing by the national standard microbiological method, people who have done it all shake their heads, which is called a difficult one. Where is the difficulty?

First of all, microbial strains need to be activated, regularly transferred and prepared for determination of bacterial liquid, which is not only complicated to operate, but also prone to differences in bacterial activity.

Secondly, the pretreatment is complicated and the operation steps are complicated. Only the standard curve needs 30 test tubes, each sample needs 24 tubes, and the spectrophotometer needs to be used to read branch by branch. If the dilution gradient is wrong, I'm sorry, start again.

Thirdly, a large number of glassware is required and thorough cleaning is required. These national standard methods all stipulate the requirements for glassware, requiring dry heating at 200 ℃ for 2 h after cleaning with active agent. Incomplete cleaning is easy to affect the test results. Therefore, the workload of cleaning and sterilization is very large.

In addition, it is necessary to operate under sterile conditions to avoid interference from other bacteria. Once improper operation is very prone to contamination.

Therefore, the national standard microbial detection method is not only cumbersome to operate, heavy workload, but also very prone to problems.

Is there a method that not only meets the accuracy and sensitivity of the national standard method, but also is simple to operate? Zhongjian Baotai vitamin test kit, so that the above difficulties and pain points no longer bother you.

Zhongjian Baotai B vitamin detection kit is improved on the basis of the national standard microbial method. Vitamin B12, biotin, folic acid, nicotinic acid, pantothenic acid detection kits have national patents.

1. The test results are equivalent to national standards.

2. Not only high sensitivity, but also make up for the shortcomings of the traditional microbiological method.

3. The operation is simple, no need to transfer bacteria regularly and increase bacteria before experiment.

The detection speed is faster, saving 3-5 days than traditional methods.

Fewer utensils are required, reducing the workload of cleaning and sterilization.

6. It is easier to calculate the results by software.
