An exploratory mixed method was conducted with four steps include qualitative, development, quantitative and interpretation. The Food Additives Module (FAM) was developed based on the basic competence of food processing and extended on chemistry content. To get the content and face validity, two experts had reviewed the FAM and gave the feedback to revise it. The analysis of FAM feasibility gained by the response of 7 chemistry teachers on four aspects includes the worthiness of chemistry concept, concept presentation, linguistics, and graphic. This study had produced the FAM module based on the contextual approach. The module had four theme namely sweeteners, preservatives, coloring and flavoring foods. A group of experts declared that the FAM was worthy as the chemistry enrichment content for vocational students of tourism field. The teacher gave a good response to the FAM quality.
