Physicohemical Properties of Doum (Hyphaene thebaica) Fruits and Utilization of its Flour in Formulating Some Functional Foods

Abstract

Doum (Hyphaene thebaica) fruit, and doum-fruit flour (DFF) were studied in terms of physicohemical properties as well as technological processing to prepare biscuits, crackers and pudding containing DFF. Chemical composition showed that DFF possessed low contents of crude protein and crude ether extract being, 2.87 and 0.76%, respectively. Non reducing sugars represented about (91.94 %) of the total sugars (43.70%). The DFF could be considered as a good source of minerals (K, Ca, Na, and Mg). The results also indicated that DFF had very good values in terms of dietary fiber, total phenolic content, flavonoid content and antioxidant activity in addition to some vitamins such as B 3 , B 6 and B 1. The edible portion of doum fruits (DFF) was used to formulate some functional foods. The organoleptic properties of biscuits and crackers containing DFF up to 20% and budding up to 50% showed that generally all the treatments were well accepted by the panelists.

Doum Palm Meal (Hyphaene Thebaica) and Partial Maize Substitution: Impact on The Blood Biochemical Indicators of Weaned Pigs

“…Although the leafy stem is used for construction, the foliage is used to make hats, mats, ropes, and baskets [11]. The doum palm is used to treat bilharziasis and its fruit is sometimes chewed to decrease high blood pressure [12,13]. [14] reported that the doum palm fruit pulp's proximate composition included the following: protein (2.86%), fat (0.92%), ash (6.24%), crude fiber (12.87%), moisture (8.64%), and carbohydrates (68.47%).…”

Development of Functional Synbiotic Flavored Fermented Skim Milk Drinks Supplemented with Doum (<i>Hyphaene thebaica</i> L.) and Carob (<i>Ceratonia siliqua</i>) Fruits Powder for Nutritional, Antimicrobial and High Antioxidant Activities

“…Doum fruit (Hyphaene thebaica L.), belonging to the family of Arecaceae [16], is widespread in the Sahel and tends to grow in areas where groundwater is present and is found along the Nile River in Egypt, Sudan [17] and Western India [16]. Doum fruit is registered as one of the most beneficial and useful plants in the world [18]. It has a taste like gingerbread and has an oblong, yellow-orange apple sized fruit with red outer skin, a thick, spongy and rather sweet and fibrous fruit pulp [19].…”
