In a word, no. Caffeine is an integral part of the tea leave's chemistry. Due to matcha's powder form you cannot separate it as you would with regular tea leaves. Decaf green tea is achievable by either harsh chemical processes which are damaging to the teas quality.
A composite factor is a factor that is a composite number, asopposed to a prime factor which is a factor that is a prime number. A factor is a number or quantity that when multiplied with another produces a given number or expression.
A composite number is a positive integer that has a factor other than 1 and itself. For instance, 6 is a composite number because: it is positive; it has a factor other than 1 and itself (both 2 and 3 are factors of 6) If you are familiar with prime numbers, then you should recognize that a positive integer is either prime or composite--these two terms are mutually exclusive. Examples of Composite Numbers. 4 4 is composite because 2 is a factor ; 8 8 is a composite number because it has 4 and 2 as factors ; non examples of Composite Numbers. 5 5 is a not a composite number because its only factors are 1 and itself (5). 5 is, however, a prime number. 2 2 is a not a composite number because its only factors are 1 and itself (2). 2 is, however, a prime number . 2 is also the even number that is not composite. Every other even number is indeed a composite number. 7 7 is a not a composite number because its only factors are 1 and itself (7).
