| Abstract | ||||
| 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. | ||||
