Abstract

A fortified date fruit product includes date fruit sugar and one or more mineral phosphate nanostructures. The mineral phosphate nanostructures can be selected from one or more of calcium phosphate, zinc phosphate, and iron phosphate nanostructures, among others. The mineral phosphate nanostructures can have a particle size ranging from about 5 nm to about 100 nm, e.g., about 5 nm to about 20 nm, about 50 nm to about 100 nm, and about 75 nm to about 100 nm.

First claim

We claim:

1. A method of preparing a fortified date fruit sugar product, comprising:
deriving a date fruit sugar syrup from date fruits;
preparing mineral phosphate nanostructures, the mineral phosphate nanostructures including at least one of calcium phosphate nanostructures, zinc phosphate nanostructures, and iron phosphate nanostructures, wherein the step of preparing mineral phosphate nanostructures comprises:
i) adding a disodium phosphate solution dropwise to a mineral chloride solution under constant stirring conditions to form a mineral phosphate mixture, wherein the mineral chloride includes at least one of calcium, zinc, and iron chloride;
ii) keeping the mixture in an autoclave at 120° C. for 2 hours to form a reaction mixture; and
iii) centrifuging the reaction mixture to obtain a mineral phosphate nanostructure, wherein the calcium phosphate nanostructures are rod shaped and have a width of 5-10 nm, and a length of 50 nm to 100 nm, the zinc phosphate nanostructures are spherically shaped with a diameter of 5-20 nm, and the iron phosphate nanostructures are spherically shaped with a diameter of 75-100 nm;

mixing the date fruit sugar syrup with the mineral phosphate nanostructures to provide a mixture;
heating the mixture at 105° C. to provide a heated mixture; and
drying the heated mixture to provide the fortified date fruit sugar product.

2. The method of claim 1 , wherein the step of deriving the date fruit sugar syrup from date fruits comprises:
adding water to a quantity of date fruits;
crushing the date fruits in the water to provide a crushed date fruit solution;
sonicating the date fruit solution; and
and filtering the sonicated date fruit solution to obtain a date fruit sugar syrup.
