Bean sprouts are common vegetables on the table. They are nutritious, tasty, cheap, fragrant, crisp and tender, and are deeply loved by consumers. In order to shorten the growth cycle of bean sprouts, increase yield and improve appearance, some people will illegally use 6-benzyladenine during the growth of bean sprouts. So, what is 6-benzyladenine? Why is it used in the process of sprouting?


What is 6-benzyladenine?
6-benzyladenine (6-BA) is a plant growth regulator and the first synthetic cytokinin. It has the effects of inhibiting the decomposition of chlorophyll, nucleic acid and protein in plant leaves, and transporting amino acids, auxin, inorganic salts, etc. it is widely used in agriculture, fruit trees, gardening and other cultivation and production processes, and has good effects in plant yield increase and preservation.

The role of 6-benzyladenine in bean sprout development

What’s the effect?
The use of 6-benzyladenine in the sprouting process is conducive to the cell division of the sprout, making the sprout strong and rootless, which will not only greatly improve the yield, but also greatly shorten the production cycle. The bean sprouts made with 6-benzyladenine have beautiful appearance, white and tender without roots, and the buds are thick. Therefore, some people use it as a growth regulator of rootless bean sprouts.


The use of 6-benzyladenine in bean sprouts in China

What are the regulations?
6-benzyladenine was once administered as a food additive. In 1996, the national food safety standard for the use of food additives (GB 2760-1996) stipulates that it can be used in the production of soybean sprouts and mung bean sprouts, and the residue is not more than 0.2 mg/kg. In 2011, GB 2760-2011 removed 6-benzyladenine from the list of permitted food additives for bean sprouts.
In 2015, the former State Food and drug administration, the Ministry of agriculture and the former national health and Family Planning Commission issued the announcement on the prohibition of the use of 6-benzyladenine and other substances in the production of bean sprouts (2015 No. 11). In order to ensure the edible safety of bean sprouts, producers are not allowed to use 6-benzyladenine in the production process of bean sprouts, and bean sprout operators are not allowed to operate bean sprouts containing 6-benzyladenine.

What are the security risks?
The Joint Expert Committee on pesticide residues (JMPR) of the United Nations Food and Agriculture Organization and the World Health Organization (fao/who) evaluated and determined that the allowable daily intake (ADI) of 6-benzyladenine was 0.05 mg/kg · BW. Excessive intake of 6-benzyladenine in human body will stimulate skin mucosa, damage esophagus and gastric mucosa, and cause nausea, vomiting and other symptoms.
According to the calculation that the residue in GB 2760-1996 is not more than 0.2 mg/kg, an adult weighing 60 kg, regardless of other food sources, eating bean sprouts of more than 15kg per day will exceed the health guidance value of 6-benzyladenine.
The use of plant growth regulators generally has a strict limit range, and exceeding the limit concentration has an inhibitory effect. The use of 6-benzyladenine in bean sprout hair production is generally not high, and its safety risk is relatively low.

Consumers need to buy bean sprouts

Focus on what?
Since January 1st, 2015, Beijing has implemented a license management system for large-scale bean sprout production of food production enterprises. When purchasing bean sprouts, consumers should focus on:first, carefully examine the bean sprout packaging, try to choose bean sprouts sold through formal channels and produced by enterprises with food production licenses, and avoid purchasing bulk bean sprouts of unknown origin; Second, choose bean sprouts without rotten roots and sharp rot. the sprouts are clear white or milky white and shiny. Avoid buying bean sprouts with thick and long appearance and no roots; Third, bean sprouts should be kept away from light and low temperature for no more than 2 days.
