Genetic carcinogens detected in 95% of coffee samples
The test found that acrylamide was detected in a total of 47 coffee samples. Acrylamide is a genetic carcinogen and neurotoxic substance. It is a pollutant produced by free amino acids and reducing sugars in food at high temperatures. Currently, there is no standard for acrylamide in food in Hong Kong. Instant coffee powder had the highest acrylamide content per kilogram, ranging from 160 micrograms to 790 micrograms. The acrylamide content of the remaining 33 models ranged from 53 micrograms to 240 micrograms. Although the detection levels of acrylamide in all samples are in line with the benchmark levels established by the European Union (roasted coffee: 400 micrograms per kilogram; instant coffee: 850 micrograms per kilogram), the test results found that the acrylamide content of the same type of coffee products has the most variation Can be nearly 4 times. Among the 49 types of coffee, only 2 samples did not detect acrylamide, including “The Coffee Academics” and “OPAL Coffee”.
Pesticides detected in 46 coffee products
The test found pesticides were detected in 46 coffee samples, 45 of which were found to contain Forbes, a pesticide commonly found in fruits and vegetables, which is an eye and throat irritant. Ortho-phenylphenol was detected in 13 models. Although its acute toxicity is not high, animal experiments have shown that it can cause bladder tumors. Another 3 models were detected with pyridaben, a pesticide commonly found in nut plants, with mild to moderate acute toxicity. And 1 biphenyl was detected, long-term intake may cause kidney poisoning or symptoms of the central nervous system. Only 3 models did not detect pesticides, including “UCC”, “The Coffee Academics” and “M&S Food”.
Heavy metals detected in 12 coffee products
The test results also showed that heavy metals were detected in 12 samples, including lead detected in 7 models, tin detected in 2 samples, and both lead and tin detected in 3 models; Food Adulteration (Metallic Contamination) Regulations, but consumers should be aware that ingestion of even small amounts of lead may cause serious health problems, especially for the nervous system of children under 6 years of age and developing infants; Excessive intake of tin may cause gastrointestinal reactions, including nausea, abdominal cramps, vomiting and diarrhea.
Long-term caffeine intake may lead to addiction
Caffeine can be used as a natural stimulant for the brain. It is a chemical substance naturally present in coffee and tea. However, long-term intake of caffeine may lead to addiction and affect sleep time, quality and melatonin secretion. The test results showed that the caffeine content detected in each sample varied widely. The instant coffee powder had the highest caffeine content per 100 grams, ranging from 2,188 mg to 4,316 mg of caffeine, while the rest of the samples (coffee beans, coffee capsules and coffee powder) ranged from 1,117 mg to 2,380 mg per 100 g. The recommended caffeine intake for an average adult is no more than 400 mg per day. If calculated according to the brewing method indicated on the sample, drinking 1 cup of coffee sample can consume up to regarding 295 mg of caffeine, which is 74% of the recommended daily intake for adults.
