Abstract

The present invention relates to novel green tea water soluble film composition comprising a) green tea extract, b) water soluble polymer mixture consisting of sodium carboxymethyl cellulose and sodium alginate, and c) additives. Green tea is conveniently prepared by dissolving the novel water soluble green tea film of the said invention in hot water.

First claim

I claim:

1. A water soluble film composition consisting essentially of a) about 40% w/w to about 60% w/w green tea extract, b) water soluble polymer mixture consisting of about 2% w/w to about 5% w/w sodium carboxymethyl cellulose and about 15% w/w to about 25% w/w sodium alginate, and c) additives.

2. The water soluble film composition according to claim 1 , wherein the additives are selected from plasticizers, diluents, sweetening agents, disintegrating agents, colouring agents and flavoring agents.

3. A water soluble film composition consisting essentially of a) about 40% w/w to about 60% w/w green tea extract, b) water soluble polymer mixture consisting of about 2% w/w to about 5% w/w sodium carboxymethyl cellulose, about 15% w/w to about 25% w/w sodium alginate and about 0.5% w/w to about 5% w/w cross-linked polyacrylate polymer, and c) additives.

4. The water soluble film composition according to claim 3 , wherein the additives are selected from plasticizers, diluents, sweetening agents, disintegrating agents, colouring agents and flavoring agents.

5. A water soluble film composition consisting of
a) about 40% w/w to about 60% green tea extract,
b) water soluble polymer mixture consisting of about 2% w/w to about 5% w/w of sodium carboxymethyl cellulose and of about 15% w/w to about 25% w/w sodium alginate based on the total weight of the film,
c) about 2% w/w to about 8% w/w of plasticizers,
d) about 7% w/w to about 15% w/w of sweetening agents,
e) about 2% w/w to about 7% w/w disintegrating agents, and
f) flavouring agents.

6. A water soluble film composition consisting of
a) about 40% w/w to about 60% green tea extract,
b) water soluble polymer mixture consisting of about 2% w/w to about 5% w/w of sodium carboxymethyl cellulose; of about 15% w/w to about 25% w/w sodium alginate and about 0.5% w/w to about 5% w/w cross-linked polyacrylate polymer based on the total weight of the film,
c) about 1% w/w to about 5% w/w diluents,
d) about 2% w/w to about 18% of plasticizers,
e) about 2% w/w to about 7% w/w disintegrating agents, and
f) flavouring agents.
