Recommended daily nutrition.

Summary of the invention

[006] The present invention is a nutrition bar allowing to utilize date seeds which are considered as waste product of date harvesting and challenging for humans to digest, and at the same time providing edible nutrient dense bar that is able to provide daily nutrition intake. The present invention is a nutrient dense bar comprising 60%wt to 70%wt of pitted dates, 30%wt to 35%wt of dried camel or Bovine milk powder, 0.6%wt to 1.3%wt of dehydrated date seed powder, 0.4%wt to l%wt of salt, and 0.15%wt to 0.45%wt of multivitamin and multimineral composition. The multivitamin and multimineral composition comprises Vitamin A, Vitamin C, Vitamin E, Vitamin D, Vitamin K, Vitamin Bl, Vitamin B2, Vitamin B3, Vitamin B5, Vitamin B6, Vitamin B7, Vitamin B9, Vitamin Bl 2, Sodium, Calcium, Iron, Potassium, Phosphorus, Iodine, Magnesium, Zinc, Selenium, Copper, Manganese, Chromium, Molybdenum, Chloride and Choline.

[007] Dates are composed of primarily sugars, specifically glucose and fructose. These sugars make up nearly 70 to 80% of the date mass. The ratio of these simple sugars is approximately 1 : 1 in most date cultivars, exception for Labanah which contains a higher proportion of glucose to fructose. This makes dates an excellent source of fermentable substrates for simple microorganisms, such as edible yeasts, molds, and other microbes as a source of protein and other nutrients. Additionally, the high sugar content is favourable to formulate the food product as a quick source of energy, binder, and preservative, as many molds, yeasts, and bacteria cannot consume high concentrations of sugars. Dates contain a significant amount of potassium, magnesium, and calcium, with trace amounts of phosphorus and sodium. Protein and fat content in date flesh is too low to be considered of any nutritional relevance.

[008] Date seeds are considered a waste product of date harvesting. However, they make up 10 to 15% of the weight of dates and contain exceptional nutrition that is, unfortunately, challenging for humans to digest. They contain a high amount of dietary fiber and valuable bioactive compounds that could be used to improve the nutritional composition of the food prototype. Date seeds are made up of between 20 to 80% dietary fiber, which can be used as a rich substrate for the production of other protein-rich ingredients using fermentation to enrich the overall protein yield of the date material. Approximately 53% of that fiber is insoluble fibers hemicellulose, cellulose, and lignin. This dietary fiber can also be included directly in the food product. The date seed is also a rich source of sodium, potassium and magnesium, with trace levels of phosphorus, selenium, calcium, iron, manganese, zinc, copper, nickel, cobalt, lead, and cadmium. One of the important components of date seeds is the protein content, which is higher than that of the date flesh. Making up approximately 5% of the total weight of the seed, the protein is composed of a moderate amount of essential amino acids methionine and lysine, as well as the semi-essential amino acid cysteine. However, date seeds are limited in their tryptophan content. Another source of protein is needed to make up the natural nutritional limitations of date seeds. The oil content is also higher in the seeds than in the date flesh, at approximately 10% of the mass. The oils of date seeds are composed of primarily oleic acid, lauric acid, followed by myristic and palmitic acid. There is a very minute quantity of linoleic acid and arachidonic acid. Date seeds also contain a high level of phenolic compounds (3102-4430 mg/100 g), which help improve gastrointestinal digestion, reduce inflammation, and increase the diversity of the microbiome over time.

[009] The following varieties of date seeds have been found to contain these nutritional elements (see table 2):

Table 2

Date Seed Varietals and Nutritional Composition

[010] Depending on the type of camel, the region it’s from, and the diet of the animal, camel milk can range in the following nutritional composition - 0.28 to 6.40% fat matter, 2.15 to 4.90% total proteins, and 2.4 to 5.8% lactose, for a total of 8 to 15% dry matter. Freeze-drying camel milk increases the dry matter mass to the following composition - 26.13% protein, 25.6% fat, and 36.6% lactose. The remainder is 7.2% ash and minerals, as well as some moisture. The protein fraction is primarily casein, which makes up 21% of the total freeze- dried mass. The remainder is whey protein, making up 5% of the powder mass. The amino acid composition is complete with all nine essential amino acids. Major amino acids include glutamic acid, aspartic acid, leucine, isoleucine, lysine, and proline. Major minerals include calcium, magnesium, phosphorus, potassium, and sodium. Trace minerals include zinc, iron, manganese, and copper. Freeze-dried camels milk also contains vitamins A, C, Bl, B2, B3, B5, B6, B9, B12, D, and E.

[011 ] It is also preferred that the nutrient dense bar comprising 63%wt to 67%wt of pitted dates, 30%wt to 35%wt of dried camel or Bovine milk powder, 0.7%wt to 0.9%wt of dehydrated date seed powder, 0.4%wt to l%wt of salt, and 0.25%wt to 0.35%wt of multivitamin and multimineral composition as mentioned in previous paragraph.

[012] Another aspect of the present invention is a method of manufacturing a nutrient dense bar comprising pitted dates, dried camel or Bovine milk powder, dehydrated date seed powder, salt, and multivitamin and multimineral composition.

[013] The method of manufacturing a nutrient dense bar comprises the following steps:

- providing pitted dates, dried camel or Bovine milk powder, dehydrated date seeds, salt and a multivitamin and multimineral composition in the form of a tablet;

- grounding multivitamin and multimineral composition tablet into a fine powder and date seeds into a fine powder;

- mixing the powdered multivitamin and multimineral composition and powdered date seeds with the salt and dried camel or Bovine Milk powder;

- blending of pitted dates until the pitted dates take on a creamy consistency;

- addition of the mix of the powdered multivitamin composition, powdered date seeds, salt and dried camel or Bovine Milk powder to the blended pitted dates; - blending the mixture obtained in a previous step until the mixture is homogenized in a paste; and

- baking the paste in oven to about 175 degrees Celsius and for about 10 minutes.

[014] Added multivitamin and multimineral composition comprises Vitamin A, Vitamin C, Vitamin E, Vitamin D, Vitamin K, Vitamin Bl, Vitamin B2, Vitamin B3, Vitamin B5, Vitamin B6, Vitamin B7, Vitamin B9, Vitamin B12, Sodium, Calcium, Iron, Potassium, Phosphorus, Iodine, Magnesium, Zinc, Selenium, Copper, Manganese, Chromium, Molybdenum, Chloride and Choline.

[015] In addition the step of baking the paste may comprise the following substeps:

- preheating the oven to about 175 degrees Celsius;

- placing an aluminium baking sheet on a cooking pan;

- placing a piece of parchment paper of the aluminium baking sheet;

- placing of the paste on the piece of parchment paper and forming the paste on the piece of parchment paper in a sheet like shape;

- placing the cooking pan in the oven and baking for about 10 minutes; and

- removing the cooking pan from the oven to allow the paste to cool.

[016] Another surprising advantage of the present invention is a minimal necessity or no necessity to use additional water supply for a nutrition bar and its manufacture. The pitted dates already have sufficient amount of water. This feature is even more crucial in regions where reach to drinkable water is limited. In some circumstances, especially during mixing of ingredients, there can be a necessity to add the water.

[017] The term "comprising" is meant not to be limiting to any subsequently stated elements but rather to encompass non-specified elements of major or minor functional importance. In other words, the listed steps, elements or options need not be exhaustive. Whenever the words "including" or "having" are used, these terms are meant to be equivalent to "comprising" as defined above.
