Does instant coffee contain caffeine?

Question

It doesn't say on the jar and it never seems to keep me that awake when I need to be, but it says its 100% coffee...so I dunno. does it contain caffeine??

Answer 1

Unless it states otherwise, then yes it contains caffeine.

Answer 2

Decaffeinated instant coffee
In commercial processes the decaffeination of instant coffee almost always happens before the critical roasting process which will determine the coffee's flavour and aroma characteristics.

Modern processes use one of two common decaffeination methods, solvent extraction or water extraction.


Solvent Decaffeination
The most commonly used solvents are trichloroethylene, methylene chloride or a similar chlorinated hydrocarbon. More recently, supercritical carbon dioxide has been used as an alternative solvent to the more hazardous chlorinated hydrocarbons.

In order for solvent decaffeination to function additional moisture is required in the coffee bean. The method for introducing this moisture does not matter, the importance is the water content of the bean, and typically anything between 18% and 55% is sufficient. The moisture is required to soften the cellular structure of the bean.

Basic steps of solvent decaffeination
Steaming of coffee beans for 30 minutes at 230 °F (110 °C).
Increase of coffee bean moisture content to above 40%.
Beans flow through extractor columns with solvent at temperatures between 120 °F and 250 °F (50 °C to 120 °C). Caffeine is removed from beans.
Decaffeinated beans are "steam stripped" of solvent for 90 minutes.
Decaffeinated beans are removed from extractors and dried.
Caffeine rich solvent is recycled to be used in step 2.

Water decaffeination
Water extraction of caffeine was first patented in 1941 by General Foods. Its claimed advantages are:

Higher extraction rates
Caffeine recovery by this method produces a purer product
Less heat treatment of the coffee bean
No direct solvent contact with the bean
This method takes about 8 hours, considerably longer than solvent decaffeination; however it does seem to produce a better quality end product.

The basic method involves the use of a water extract of green coffee beans in a battery of columns in contact, countercurrently, with green beans. As contact is made the green beans preferentially absorb water. The solid content of the water extract of green beans doubles (from 15% to 30%) as caffeine is taken up. During the 8 hour process about 98% of the caffeine is removed, which is comparable with the solvent extraction method. The decaffeinated beans, now 58% moisture by weight, are washed and dried.

Answer 4

Yes. There is decaffeinated instant coffee, but that word must be on the label. Folgers' instant has a mostly brown label, whereas Folger's instant decaf has a mostly green label. But be sure you look for the word "decafeinated" because manufacturers change labels periodically.

Answer 5

It is coffee..unless it says otherwise it would contain caffeine.

Answer 6

Yes it does that is why they have decaf, coffee as well, but I don't think it tastes as good as normal coffee..

Answer 7

Yes, it does, but less than brewed. See the link below for comparisons.

Answer 8

unless it says decaf then its got caffeine in it. in fact even de caf has caffeine in it.

Answer 9

yes

Answer 10

yes of course even if it is a processed product
