NUTRITIONAL VALUE OF TIGER NUT (CYPERUS ESCULENTUS L.) TUBERS AND ITS PRODUCTS

The purpose of this study is to identify the nutritional value of
tiger nut tubers and their products. Tiger nut tubers (Cyperus
esculentus L.,) cultivar were collected from Tanta city, Egypt. The
chemical composition and mineral analysis of tiger nut tubers were
determined. Extraction of oil and determined of some physico-
chemical properties of oil and identification of fatty acids composition
(%) by gas liquid chromatography (GC). Also, identify of amino acids
in tiger nut flour by amino acid analyzer. Preparation of tiger nut milk
was processed in lap and compared with soymilk as a control. Also,
microbial content of tiger nut milk were determined. In addition to,
sensory evaluation of milk made from tiger nut was determined. The
obtained data for the composition of tiger nut tubers indicated that the
moisture content of tiger tubers was 8.50%. The carbohydrate content
of tiger nut tubers was found to be the first component in these tubers
(45.73%) followed by oil content (30.01%). moreover; protein, ash
and crude fiber of tiger nut tubers were 5.08%, 2.23% and 14.80%
respectively. The results provide additional information about the
nutritional value and confirm that of tiger nut tubers are an interesting
healthy food such as imitation milk.
