ABSTRACT

Public awareness of high-quality, nutritious foods and their effects on human health has risen sharply over the years. Well embroiled within the evolution of consumer food preferences are functional foods and their growing role as healthy foods for general well-being and disease prevention. The development of functional foods has been driven by mounting evidence of health
