ABSTRACT

Selenium (Se) has been recognized as an essential nutrient for humans. Plant foods are the predominant source of selenium and majority of dietary selenium is absorbed depending on the type of food consumed. Nowadays, green tea is becoming increasingly popular for its prominent health benefits, including the ability to supplement selenium in organically bound, natural food form. The selenium content of Se-enriched green tea is influenced by the selenium level of local soils in which it is grown. However, selenium content of plants can also be improved by artificial fortification methods. In this review, the chemical speciation and biological functions of selenium, fortification methods, biological activities and nutraceutical applications of Se-enriched green tea are discussed. This review provides insights into the current research and the importance of Se-enriched green tea in the enrichment of human nutrition and health.

ABSTRAK

Selenium (Se) telah dikenal pasti sebagai nutrien yang penting bagi manusia. Tumbuhan adalah sumber utama selenium dan majoriti diet selenium diserap bergantung kepada jenis makanan yang dimakan. Pada masa kini, teh hijau menjadi semakin popular sebagai khasiat kesihatan, termasuk keupayaan suplemen selenium dalam bentuk makanan organik asli. Kandungan selenium teh hijau diperkaya-Se dipengaruhi oleh tahap selenium tanah tempatan di mana ia ditanam. Walau bagaimanapun, kandungan selenium tumbuhan juga boleh ditingkatkan dengan kaedah penguatan tiruan. Dalam kajian ini, penspesiesan kimia dan fungsi biologi selenium, kaedah penguatan, aktiviti biologi dan penggunaan nutraseutikal teh hijau diperkaya-Se dibincangkan. Kajian ini memberi pemahaman tentang penyelidikan dan kepentingan teh hijau diperkaya-Se dalam memperkaya pemakanan dan kesihatan manusia.

 

Kata kunci: Aktiviti biologi; nutrisi dan kesihatan; penggunaan; selenium; teh hijau
