After the "first cup of milk tea in autumn" is consumed, claims such as "one cup of milk tea has caffeine content equal to four cups of coffee" and "one cup of milk tea wakes up until dawn" have once again caused milk tea enthusiasts to struggle. Can you drink milk tea with peace of mind? Take a look at the "Chinese Consumer Caffeine Cognition and Attitude Survey (2023)" by the Kexin Food and Health Information Exchange Center. According to relevant market research institutions, more and more consumers are looking for foods and beverages that can affect cognitive ability, manage stress levels, and optimize brain function after the epidemic, with caffeine being considered one of the most promising ingredients for development. This survey shows that the most anticipated effect of caffeine on consumers is to refresh their minds (91.56%), followed by improving exercise performance (45.47%), improving reaction speed (38.75%), and improving cognitive function (36.12%). Researcher Liu Ailing from the Institute of Nutrition and Health of the Chinese Center for Disease Control and Prevention believes that caffeine can have various effects on the human body. It can promote the release of neurotransmitters, enhance neuronal activity, thereby increasing central nervous system excitability, increasing alertness, attention, and more. However, excessive caffeine intake may lead to symptoms such as palpitations, nervousness, insomnia, gastrointestinal discomfort, etc. Therefore, consumers should pay attention to moderate consumption. Half of consumers are unaware that caffeine in tea naturally exists in various plants, and drinking coffee is not the only way to obtain caffeine. The results of the "Dietary Caffeine Intake Level and Risk Assessment of Chinese Residents" show that for adult consumers in China, the highest contribution rate of caffeine intake is in order of tea, tea drinks, milk tea, and coffee; The contribution rate of tea to the caffeine intake of Chinese consumers is 74.80%, which is much higher than other categories. The highest contribution rate of caffeine intake among minors is in the order of milk tea, tea drinks, tea leaves, and chocolate. However, this consumer survey shows that 52.15% of people are unaware that tea contains caffeine. Zhong Kai, director of the Kexin Food and Health Information Exchange Center, stated that tea and coffee are both popular caffeine drinks worldwide. However, when it comes to caffeine, it's easy for consumers to "take it literally" and only associate it with coffee. But in fact, both tea and milk tea also contain caffeine, and what people often say is' drinking tea to refresh oneself 'is actually the effect of caffeine. Caffeine naturally exists in various plants, including tea, such as coffee beans, tea leaves, cocoa beans, guarana leaves, Paraguay tea, etc. The survey shows that consumers have the highest awareness rate of "coffee bean extract" at 89.10%, but their recognition rate of other caffeinated ingredients is relatively low. For example, 51.79% of consumers are unaware of the caffeine content in "black tea concentrate", 63.42% of consumers are unaware of the caffeine content in "Paraguay tea extract", and 76.05% of consumers are unaware of the caffeine content in "Guarana extract". Li Yu, Chief Engineer of the China Food Industry Association, believes that currently, caffeine is only allowed for some health foods and cola carbonated beverages in China. However, caffeinated ingredients such as coffee powder, tea powder, and guarana extract can also be brought in. These contain coffee
