3.6 Time induced behavior on food evaluation
In order to verify the shelf-life expansion of food packaging made by the LDPE and EVA blended film with these EOs, four different set of packaging films, namely blended film without EOs (control film) and the film incorporated with CL, SB, CB would be used to pack a piece of sliced tomato. A series of visual inspection at different time line were photographically documented as shown in Table 4. The tomato in the control film started to spoil on the 20th day wheareas the ones packed in the film incorporated with EOs did not show any noticable sign of spoilage. After two months, the tomato packed in control film was covered with mold and fungi. Surprisingly, the ones packed in the films incorporated with any given EOs illustrated of the well-kept conditions. Thus these films could be modified for the usage of food packaging with its high potency candidate as the substrates against microorganisms.
