Abstract

The objectives of this science project were to develop the biopolymeric capsule shells from tomato cutin
and chitosan and investigate on the properties of capsule shells prepared from different composition
ratios between cutin and chitosan. The capsule shells would be suitable for patients having difficulty in
drinking water after taking the capsule. The development of these capsules from tomato cutin and
chitosan derived from shrimp shell which are the agricultural wastes from food production also provides
the benefit of optimum use of the natural resource. The water resistance and dissolution studies revealed
that the film of cutin and chitosan at the ratio of 1 : 2 exhibited the advantages for capsule shell
application, therefore, this composition ratio was used for capsule shell fabrication. The obtained
capsule shell were compared with the capsule shell from cutin, chitosan and gelatin at the ratio of 1 : 1
: 1 and the commercial gelation product in terms of swelling and dissolution behavior, moisture content,
physical properties and processability. It was found that the biopolymeric blend obtained from tomato
cutin, chitosan and gelatin have strong potential for the application of capsule shell product.
