ABSTRACT
Interest in nutraceuticals and functional foods continues to grow, powered by progressive research efforts to identify properties and potential applications of nutraceutical substances, and coupled with public interest and consumer demand. Estimates vary; global market size for functional food ingredients is projected to exceed 250 billion by 2025. Among the principal reasons for the growth of the functional food market are current population and health trends. Across the globe, populations are aging. For instance, in 2015, the average projected life expectancy globally for those born that year was 71.4 years. Moreover, about 30 countries recorded average life expectancy at 80 years or above, including Japan, Singapore, and Switzerland, all above 83 years. 1
