Abstract

The objectives of this study were to characterize and utilize the seeds flour of two species of cucurbitaceae with wheat flour for biscuits making. Cucurbitaceae species used were (Tibish) Cucumis melo agrestis and (Fagoos) Cucumis metuliferus obtained from Khartoum and Darfor, respectively, season 2011/12. The cucurbitaceae seeds were milled into flour by warring blender then proximate analysis, minerals composition and protein fractions were conducted. Biscuits were made from cucurbitaceae seeds flour and wheat flour in ratios 5:95, 10:90 and 15:85 respectively. Organolyptic quality of biscuits was investigated. Proximate analysis of the seeds flour revealed that the crude protein was 26.1 and 27.0% respectively, crude fat was 26 and 33.3%, crude fiber 24.8 and 25%, ash 2.8 and 5.3 respectively. The results proved that the two species contained height amount of minerals especially iron (7.4 mg/100 g and 5.7 mg/100). Protein fractions showed that the water- and salt-soluble proteins (albumin and globulin) of the two species of cucurbitaceae seeds flour were the ranges of (32.4, 35.1) and 26.57 to 28.7% respectively, prolamin and glutelin fractions were (10.9, 11.15) and (23.85, 19.7%), respectively. The highest spread ratio of the wheat biscuits and composite cucurbitaceae seeds flour biscuits was observed in 5%Fagoos (3.63) and the lowest in 15% Tibish (4.07). The mean quality scores for the overall acceptability was highest in 15%Tibish (7.87) and the lowest score of (4.5) was obtained by 5% Fagoos. In conclusion the results revealed that the good nutritional value of seeds flour reinforced the usefulness of cucurbitaceae seeds flour in biscuits making.

Highlights

The cucurbitaceae is a predominantly tropical plant family of about 130 extant genera and 900 species, the over-whelming majority of which are distributed in Africa, Madagascar, Central and South America and Southeast Asia [1]
The results were above of the finding of Mariod et al, [20] who concluded that the protein content of seeds of tibish and fagoos were 16.6% and 14.5%, respectively
A according to Table 1, oil of the two species of cucurbita seeds flour (Tibish and Fagoos) were 27.17% and 34.25% respectively, the highest oil content was obtained by Fagoos

Summary

Introduction

The cucurbitaceae is a predominantly tropical plant family of about 130 extant genera and 900 species, the over-whelming majority of which are distributed in Africa, Madagascar, Central and South America and Southeast Asia [1]. In tropical Africa, cucurbitaceae distributions especially characteristic of the drier regions [2], the cucurbitaceae are an important source of vegetables, fruits, edible seeds and seed oil, domestic utensils, medicines, water, animal fodder and fuel. In spite of this potential, less than 0.5% of the species are being commercially exploited and the family is relatively poorly known. In order to have a healthy population that can promote development, the relation between food, nutrition and health should be reinforced. One of the ways of achieving this is through the exploitation of available local resources, in order to satisfy the needs of the increasing population
