Production And Characterization Of Natural Date Fruit Powder (Pheonix Dactylifera L.), Fayeza Hasan
Production And Characterization Of Natural Date Fruit Powder (Pheonix Dactylifera L.), Fayeza Hasan
Theses
The aim of this thesis was to study the possibilities for production and the characterization of powder from ripened date fruits (Phoenix dactylifera L.). Various techniques including tray drying, freeze-drying, vacuum drying, microwave drying, convection drying were tested for their ability to dry the dates sufficiently to produce a dated powder. Six varieties of dates namely Barhi and Khalas (soft varieties), Sagi and Sukari (semi-dry varieties), and Barakawi and Gundeila (dry varieties) were evaluated for their drying characteristics. The drying parameters and the physicochemical characteristics were compared and a storage study for the date powder was conducted. It …
Date Fruit Fiber Variability In Composition, Tissue Distribution, And Contribution To Hardness Of Date Fruits (Phoenix Dactylifera L.), Navomy George
Date Fruit Fiber Variability In Composition, Tissue Distribution, And Contribution To Hardness Of Date Fruits (Phoenix Dactylifera L.), Navomy George
Dissertations
Date fruit (Phoenix dactylifera L.) is a major desert crop and is an integral part of the United Arab Emirates. This study is on the various aspects of dietary fiber of ten Emirati date varieties. The main objective of this dissertation is to analyze the content and composition of mature date fruits and to study their microstructure. The aspects of biomineralization with particular importance to silica phytoliths and lignification are also studied. Finally, the date fruit dietary composition and microstructure are related to the textural attributes of the fruit. Uppsala method of dietary fiber analysis (AOAC 994.13) is used …
Hyperspectral Properties Of Date Palm Trees (Phoenix Dactylifera L.), Mohamed Ali Saeed Ahmed Al Abdouli
Hyperspectral Properties Of Date Palm Trees (Phoenix Dactylifera L.), Mohamed Ali Saeed Ahmed Al Abdouli
Theses
The goal of this study is to classify the Date Palm varieties based on hyperspectral signature technology since it is difficult to identify the Date Palm cultivars without fruits. It will also help to obtain the hyperspectral signature for different types of date palm trees. Moreover, it also assists to determine the wavelength fingerprint of each cultivar and to recommend the best classification protocol differentiating among different cultivars based on spectral signature. Utilizing the Hyperspectral imaging technology precisely on the leaves of different Date Palm cultivars, thus facilitating identification of date palm cultivars without the fruits and make the spatial …
