How much caffeine does a mars bar have?

Milk chocolate has very little caffeine. Generally only dark chocolate has any appreciable amount of caffeine.

Nhs guidelines suggest a 50g bar of milk choc would have approximately 25mg. The amount of actual chocolate in a Mars bar is small so caffeine will be slight. Won't bring you anywhere near the 200mg recommended daily limit. A Mars bar will have almost no caffeine.

A mars bar is 58g total, milk chocolate makes up ~ 40%. So 23g of milk chocolate would be about 5mg of caffeine. To put that in perspective the average cup of coffee has 95mg of caffeine.

Does tea have more caffeine than coffee?

A cup of coffee tends to have much more caffeine than a cup of tea.

Tea (including black tea, green tea, white tea, oolong tea, etc.) tends to have about 15-70mg of caffeine per 8 oz. cup, whereas the same size cup of coffee tends to have about 80-135mg of caffeine. You cannot generalize about one type of tea (black, green, etc.) containing more or less caffeine.

However, by dry weight, tea actually contains substantially more caffeine than coffee. This fact can be misleading, since when brewing coffee, one uses more coffee grounds by weight than one uses tea. Tea is very light, and typically, only 2-3 grams of loose tea leaf are steeped to produce an 8 oz. cup of tea.

The brewing method for tea (and to some degree for coffee) can have a large effect on the caffeine content. For tea, using more leaf, and steeping for longer times, can result in a much higher caffeine content in the finished cup.

Do apples have as much caffeine as coffee?

No. Not even a little bit. Apples, as a pomaceous fruit, do not naturally contain caffeine. They do, however, have about 19 grams of sugar for one average medium - natural sugar, which is much healthier than the 4 grams of Sweet 'N Low mixed into your daily coffee. So despite the high sugar levels, eating an apple is a much healthier alternative to drinking coffee. The sugars are also one of the main reasons apples have similar effects to caffeine.

Does ginger ale green tea have caffeine?

The amount of caffeine in green tea is widely variable. A lot of sources claim that green tea is lower in caffeine than black tea, but this is not necessarily true. It's hard to generalize about whether green or black teas contain more or less caffeine.

Nearly all tea, however, has much less caffeine than coffee.

People sensitive to caffeine and drinking green tea as an alternative should be aware that green tea still contains caffeine which will affect you if you drink several cups.

Green tea is generally brewed with water below the boiling point for 2-4 minutes. Longer steeping times can result in more caffeine being released into the cup. The amount of leaf used also influences the caffeine content.

Why caffeine is used for calibration of HPLC?

Caffeine responds in 3 wavelength regions i.e

196 - 208nm in which caffeine maxima at 203±2nm

240 - 248nm in which caffeine minima at 244±2nm

270 - 278nm in which caffeine maxima at 273±2nm

So it covers the operation range of HPLC UV detector to perform wavelength accuracy.

Apart from this Caffeine elutes in approx 2 min when using any C18 column which helps in reducing run time.

That s the caffeine is preferred than any other standards for HPLC calibration

What is caffeine?

Caffeine is a bitter white crystalline xanthine that acts as a psychoactive stimulant drug and a mild diuretic (speeds up urine production) in humans and other animals. Caffeine was discovered by a German chemist, Friedrich Ferdinand Runge, in 1819. He coined the term "kaffein", a chemical compound in coffee, which in English became caffeine. Caffeine is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea; all of these names are synonyms for the same chemical compound.

Caffeine is found in varying quantities in the beans, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the beans of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. Other sources include yerba mate, guarana berries, and the Yaupon Holly.

In humans, caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Beverages containing caffeine, such as coffee, tea, soft drinks and energy drinks enjoy great popularity. Caffeine is the world's most widely consumed psychoactive substance, but unlike most others, it is legal and unregulated in nearly all jurisdictions. In North America, 90% of adults consume caffeine daily. The U.S. Food and Drug Administration lists caffeine as a "Multiple Purpose Generally Recognized as Safe Food Substance.One 2008 study suggested that women consuming 200 milligrams or more of caffeine per day had about twice the miscarriage risk as women who had none, while another 2008 study found no link between miscarriage and caffeine consumption.

Caffeine is a naturally occurring white bitter alkaloid found in the seeds and other parts of plants, particularly coffee. It acts as a natural insecticide for the plants, helping to control and even kill some of the insects that would feed on the plants, and and the same time it acts as a reward mechanism for insects that pollinate the plants. In humans it acts as central nervous system (CNS) stimulant.
