This book serves as a platform for the global community of halal researchers to share their insights on approaches to solve halal industry issues through science. The global halal industry is estimated to be worth around USD2.3 trillion (excluding Islamic finance). Growing at an estimated annual rate of 20%, the industry is valued at about USD560 billion a year, making it one of the fastest-growing consumer segments in the world. The global halal market of 1.8 billion Muslims is no longer confined to food and food-related products. This book brings together research carried out through halal sciences to solve issues in halal industries, covering topics such as general issues in halal industries, the level of verification and authentication, finding alternative materials or ingredients that are halal in pharmaceutical and food industries, as well as legal issues that could arise. This book is useful to graduate students in universities, researchers, academics, and industry practitioners working in halal industries.
