Terrifying harm when 'dyeing' coffee with battery core

If the amount of manganese in the core of dry cells absorbed into the body is high, it can cause memory impairment, nervous system, and motor movement.

MSc Hoang Trong Phu, lecturer in Faculty of Chemistry at the University of Natural Sciences (Ho Chi Minh City National University), said that people now use many ways to produce black coffee such as burnt popcorn and caramel. If using a battery of coffee dye is very rare, it can be profitable.

According to MSc, in the process of creating a dry battery like battery type, the manufacturer must use a manganese dioxide compound (MngO ₂ ) , the dark brown color around the graphite core which is electrically conductive as a substance. The power dissipation releases power to the battery core. Cooking pin cores will more or less cause manganese dioxide to enter the user's body, negatively affecting the nervous system. To test the level of toxic manganese dioxide to users' health, it is necessary to test the coffee sample.

According to the regulations of the countries in the world, the battery factory must be responsible for recovering and disposing of batteries due to the storage of some heavy metals such as Manganese, which may follow the source of water that is naturally polluted. , according to the source of water entering the human body. In Vietnam, batteries are discharged blameless.

As for Assoc. Prof. Dr. Nguyen Duy Thinh (former staff of the Institute of Biotechnology and Food - Hanoi University of Science and Technology), the fact that there are many ways to color coffee safely like using caramel has been allowed. . He said batteries are not allowed to be used in manufacturing and processing any kind of food. Dyeing coffee with battery cores is unique but confusing and affecting great confidence for consumers. Facility owners who use batteries for food processing should be subject to appropriate penalties and extensive information.

Harmful to the nervous system

The Ministry of Health has made many recommendations about the harmful effects of manganese on human health and people often exposed to manganese.

According to the Ministry of Health, manganese is one of the basic microelements of life, playing many important roles in the body such as: impact on cellular respiration, bone growth, metabolism of glucose and actives. brain activity . Although it does not cause direct impact on human health, but if exposed, eating, using manganese-contaminated water sources for a long time also leave bad and dense consequences. especially for the nervous system.

Manganese is present in water in the form of soluble ions (Mn2 +). If the content is less than 0.1mg / liter, manganese is beneficial for health. However, if the manganese content of 1-5mg / liter is high, it will cause many effects on some organs of the body.

Manganese does not have the ability to mutate or form dangerous diseases like cancer, nor does it affect reproduction . but it is closely related to the nervous system, causing toxins to form manganism syndrome. with symptoms similar to Parkinson's disease. If the amount of manganese absorbed into the body can be toxic to the lungs, nervous system, kidneys and heart. When inhaled manganese in large quantities can cause poisoning syndrome in animals, causing nerve damage.

Manganese is particularly harmful to children because the body is easily absorbed by many children while excreting is very small. That leads to the accumulation of manganese in the young body, causing serious consequences. Therefore, health experts recommend that pregnant women and children absolutely avoid contact and use of manganese-contaminated water.

Using long-term sources of manganese-contaminated water, manganese toxicity from drinking water reduces language ability, memory loss, decreased mobility related to the hands and eye movements, if manganese poisoning lasts for a long time. can lead to abnormal neurological symptoms such as gait and abnormal language.

In fact, manganese exists in nature very much and it can be said that their form of existence in water is the least effective.

In addition, people often exposed to manganese are prone to neurological symptoms, initially headache, weakness, poor sleep, balance disorders, awkward, awkward gait. In the developmental phase, there will be symptoms similar to Parkinson's syndrome, mild tremor, and work, but then severe tremor, severe illness, no labor and self-service.

Manganese poisoning can occur in many forms. The most common form is the nervous system. In addition, there are endocrine, hematological, gastrointestinal disorders, liver, kidney, lung and nasopharyngeal lesions.
