CHAPTER ONE

1.1   INTRODUCTION

Tiger nut is a tuber that is grown in the soil. It has a dimension ranging from 6-10 mm and occurs in different varieties. The colour is brown and has a sweet flavor when eaten. Tiger nut has been used extensively mainly for human consumption in Spain (Mason, 2008; Tiger nuts Traders, 2009). Tiger nuts are prepared and eaten cold as snacks. The milk can be extracted, treated and bottled. The flour is used to make cakes and biscuits and the oil is used for cooking (Wise, 2009). In United Kingdom, tiger nut is superb bait for carp fishing (Wise, 2009).

In Nigeria, the utilization of tiger nut is highly limited in spite of the fact that tiger nut is cultivated widely in the Northern part of the country. Tiger nuts are eaten raw mainly as snacks or fried and eaten mixed with roasted groundnuts (Abaejoh et al., 2006).

Kofi (1990) reported that sweetened tiger nut extract are bottled and sold in Ghana.
