Allyl isothiocyanate (AITC), a naturally occurring antim icrobial compound, is an effective inhibitor of various pathogens, but its use in the food industry is limited by its volatility and pungency. The objective of this study is to overcome the volatility of AITC using dried Laminaria japonica as its carrier. The powder of Laminaria japonica will be prepared with different particle size; 500 μm, 710 μm and 900 μm. AITC loading into raw and deoiled Laminaria japonica powder will be achieved using two different systems, vapor adsorption and complexation. Vapor adsorption will be carried out by heating small tube containing 10 ml liquid AITC inside a sealed larger vial containing 5 g powder sample at 60 °C and 101 kPa. Complexation of AITC with Laminaria japonica powder will be conducted by adding the powder sample directly into AITC solution at constant temperature (25 °C) and pressure (101 kPa). The study of AITC adsorption and desorption will be determined by monitoring sample weight changing with time. The quantification of AITC will be analyzed by gas chromatography (GC). AITC present in Laminaria japonica powder will be studied by FTIR spectroscopy.
