The International Halal Science Conference (IHASC) is jointly organised by the International Institute for Halal Research and Training (INHART), International Islamic University Malaysia, University Islam Sultan Sharif (UNISSA) and Halal Development Corporation Berhad (HDC) with the theme – Halal Industry Sustainability Through Science. Halal Science could be defined as Halal knowledge that attained systematically through observation and experimentation study and practice to describe and explain on the natural phenomena that relates to Halal practice. Halal Science is an important aspect that will support the integrity of what we called as Halal product or Halal services. Halal itself is holistic and comprehensive such that the sciences of halal can sit anywhere in the spectrum of social science, humanities, applied science and technology. With the increasing of global interest on the Halal product and services, it is timely for INHART, UNISSA and HDC to jointly organise this conference.
