Essential oils are highly concentrated plant extracts, a single drop potentially containing the essence of dozens of plants. This raises a common question: do essential oils have calories? While they contain organic compounds, the definitive answer is that they do not contribute meaningful dietary energy, and consuming them is dangerous.

According to the National Institutes of Health, caffeine is a colorless, odorless alkaloid that requires temperatures far exceeding water's boiling point to vaporize. This fact is key to understanding the science behind the question: does tea steam have caffeine? The answer, surprisingly, is no, and the reasons lie in fundamental chemical properties that differentiate the bitter compounds in your cup from the pleasant aroma that rises from it.

Research shows VOC concentrations can range widely in everyday foods, from natural flavor compounds in citrus to contaminants like benzene in cooked meats. Understanding what foods contain VOCs helps in appreciating the science behind food aroma and safety.

According to botanists, a fruit's flavor is defined by a complex interaction of taste and aroma, influenced by non-volatile compounds like sugars and acids and hundreds of volatile compounds. So, why do plants taste different, and what's responsible for the unique flavor profiles of different produce? The answers lie in a fascinating interplay of genetics, environment, and evolutionary biology.

Approximately 99% of tequila's chemical composition consists of ethanol and water, but the remaining 1% is a complex blend of hundreds of minor compounds that create its distinctive flavor profile. Understanding what chemicals are in tequila reveals how the agave plant, yeast, and aging process contribute to its rich and varied character.

Correction fluid, commonly known as whitener, contains a mixture of toxic chemicals, including volatile organic compounds (VOCs). An estimated 5% of eighth graders in the United States have reported inhalant use, highlighting a significant public health issue. Is whitener good for health? The unequivocal answer is no, and understanding its dangers is crucial.

Recent research has shown that volatile organic compounds are key indicators of honey quality and botanical origin. This discovery raises the question: does honey contain linalool, a well-known floral and citrus terpene? The short answer is yes, many honeys do, but its presence and concentration vary significantly based on several factors, including the source of nectar and processing methods.

According to a University of Nebraska–Lincoln study, properly conducted distillation can remove up to 99.5% of impurities from water. This remarkable effectiveness leads many to wonder, "Does distilling water remove all toxins?". However, the simple boiling and condensing process has a few critical limitations that must be understood to achieve truly pure water.

Methanethiol, a compound known for its pungent, rotten-cabbage-like odor, is a naturally occurring volatile sulfur compound found in many foods. Understanding what foods have methanethiol can help explain certain strong aromas and flavors in your diet, from cheeses to coffee.

Over $45 billion is spent on toys globally each year, and among the most popular are 'squishies', but a common misconception leads many to ask, 'How many calories are in squishies?'. In reality, squishy toys contain no calories because they are not food; the question likely stems from confusion with a similar-sounding confectionary product. This critical distinction is vital for both nutritional awareness and child safety.
