DETERMINATION OF DIHYDROCHACLONE CONTENT IN RICE VARIETIES 2

Major Effect of Fuel Subsidy Removal

CHAPTER ONE
1.0                          INTRODUCTION
Rice consumption in Nigeriais higher than the others commodities, and making Nigeria as the largest producer in Africa(Moldenhaueret al., 2003).Rice has been recognized as an excellent source of vitamins and minerals, but has been under-utilized as human food. Research conducted in the last two decades has shown that it contains a unique complex of naturally occurring antioxidant compounds (Moldenhaueret al., 2003).

Rice as a product of paddy milling contained protein, carbohydrate, dietary fiber, ash, fat, vitamin, mineral and natural antioxidant compounds (Chen et al., 2008). Rice also contains phytochemical compounds in significant amount and these compounds have been considered as natural antioxidant. Rice according to Chen et al. (2008) contained 95.6% saponified lipid such as glycolipid and phospholipid and 4.2% unsaponified lipid such as tocopherol, tocotrienol, γ-oryzanol, sterol and carotenoid.
Amongst rice varieties there are rice varieties that contain color pigments. The cultivars of pigmented rice have a long history for human consumptions, especially in Ebonyi State, South East, Nigeria (Hu et al., 2003). These compounds ......................................................

AIM AND OBJECTIVES

Aim
To evaluate the dihydrochaclone content of some selectedAbakaliki Rice varieties.
Objectives
1.     To quantitative measure the content ofdihydrochaclone in different rice varieties?
2.     To compare the concentration of dihydrochaclone content among Abakakliki cultivars.

 LITERATURE REVIEW

2.1 RICE                                              
Rice refers to two species (Oryza sativa and Oryzaglaberrima) of grass, native to tropical and subtropical Southern and Southeastern Asia and to Africa, which together provide more than one fifth of the calories consumed by humans (WARDA, 2011).  (The term "wild rice" can refer to wild species of Oryza, but conventionally refers to species of the related genus Zizania, both wild and domesticated) (WARDA, 2011).
Rice is an annual plant, growing between 1–1.8 m tall, occasionally more, with long slender leaves of 50–100 cm long and 2–2.5 cm broad. The small wind-pollinated flowers are produced in a branched arching to pendulous inflorescence 30–50 cm long. The seed is a grain (caryopsis) 5–12 mm long and 2–3 mm thick (WARDA, 2011).
