Description:FIELD OF INVENTION
The field of the present invention relates to food technology, functional foods, and nutraceutical product development, particularly to the formulation of plant-based, no-bake, clean-label confections. More specifically, it pertains to the preparation of vegan, gluten-free, refined sugar-free chocolate-based functional snacks incorporating natural sweeteners, seeds, and bioactive ingredients that provide balanced nutrition, enhanced shelf stability, and health benefits such as antioxidant, metabolic, and digestive support.

BACKGROUND OF INVENTION
Conventional nutraceutical and snack products often rely heavily on refined sugars, artificial preservatives, and synthetic emulsifiers, creating health concerns and limiting their long-term benefits. Many commercially available snack bars and confectioneries are formulated with high-glycemic sweeteners, which cause rapid spikes in blood glucose levels, increase cravings, and may contribute to metabolic syndrome and type 2 diabetes. Additionally, these products frequently contain hydrogenated fats and low-quality fillers that lack essential micronutrients, dietary fiber, and beneficial fatty acids. Consumers seeking nutrient-dense, clean-label, and plant-derived snacks with functional health benefits often find limited options that combine both appealing taste and scientifically relevant nutrition.
This invention addresses these challenges by providing a nutraceutical composition incorporating chocolate, Medjool dates, and a multi-seed blend comprising watermelon, sunflower, pumpkin, chia, flax, soynut, and sesame seeds. The composition delivers plant-based protein, unsaturated fatty acids, dietary fiber, antioxidants, and essential minerals while avoiding refined sugar, dairy, and synthetic additives. Medjool dates act as both a natural sweetener and binding agent, offering slow-releasing carbohydrates for sustained energy without the drawbacks of processed syrups. The inclusion of chocolate and almond butter enhances palatability and consumer acceptance while maintaining the nutritional value of whole food ingredients.
A particular problem solved by the invention is the scarcity of functional, confection-like nutraceuticals that remain stable without baking or synthetic stabilizers. By employing a no-bake method, the invention preserves heat-sensitive bioactive compounds, ensuring retention of antioxidant capacity and micronutrient integrity. Furthermore, the composition eliminates the use of artificial flavorings, emulsifiers, and preservatives, offering a clean-label, shelf-stable nutraceutical product. Designed for active individuals, health-conscious consumers, and those adopting plant-based dietary preferences, the invention provides a convenient, portion-controlled, ready-to-eat format that supports balanced nutrition, sustained energy, and overall wellness.

US20230354844A1 disclosed a chocolate confection free from dairy, gluten, and animal products, and a process for making such a confection are disclosed. In the chocolate confection of this invention, traditional milk chocolate's milk solids are replaced by heat-treated legume flour. Heat-treated legume flour contributes desirable flavor and texture properties to the chocolate confection. Legume flours generally contain relatively low amounts of sugar and high amounts of both protein and fiber. They are also suitable for reduced-sugar chocolate formulations.
US20050002989A1 disclosed nutrition bar comprising; about 10% wt or more of soy and/or rice protein, at least one transition metal or transition metal compound, and about 2% wt or more of a humectant, and wherein the at least one transition metal or transition metal compound is in a substantially water insoluble form at 20° C. or the nutrition bar has an Aw of 0.45 or less or about 1% wt or more of the soy and/or rice protein is in the form of nuggets and the humectant is selected from polyols. The bars have elevated levels of soy and/or rice protein, yet do not suffer unacceptable from a deterioration in taste or other organoleptic properties over time.
US4451488A disclosed a shelf stable, intermediate moisture, food bar having a soft and chewy texture with good taste is disclosed. Lowered sugar content and good texture and taste characteristics are maintained through the use of a combination of at least two polyhydric alcohols in varying ratios, one of which comprises a sugar alcohol and the other either glycerol or propylene glycol. In preferred embodiments the two polyhydric alcohols are glycerol and sorbitol employed in a ratio of glycerol to sorbitol in the range 1:1 to 5:1. Despite a low total sugar content the water activity may be maintained in the 0.2-0.55 range through the use of such polyhydric alcohols while achieving a soft texture.
Research gap
Although numerous confectionery and nutraceutical products exist, most commercially available chocolate-based snacks rely on refined sugar, artificial sweeteners, synthetic stabilizers, or processed protein powders. Such formulations often compromise nutritional integrity and fail to provide a balanced combination of natural macronutrients and micronutrients. While dates and seeds are individually recognized for their health-promoting properties, limited research has explored their synergistic incorporation into a stable, chocolate-based nutraceutical composition with proven physicochemical attributes. Additionally, very few existing products are supported by standardized analytical characterization such as moisture, protein, fat, vitamin C content, and amorphous nature by XRD. This reveals a gap in developing a scientifically validated, functional chocolate-date-seed formulation that is naturally sweetened, nutrient-dense, structurally stable, and suitable for extended storage without chemical preservatives.
None of the prior art disclosed what the present invention disclosed. Present invention relates to a nutraceutical composition incorporating chocolate, medjool dates and a multi-seed blend.
SUMMARY OF INVENTION
This invention relates to a nutraceutical composition that integrates plant-based nutrition, clean-label formulation, and functional food technology by incorporating chocolate, Medjool dates, and a multi-seed blend. Unlike conventional confectionery or snack products, the formulation avoids refined sugar, dairy, and synthetic additives by employing Medjool dates as a natural sweetener and binder. A diverse seed mixture comprising watermelon, sunflower, pumpkin, chia, flax, soynut, and sesame delivers plant-derived protein, omega fatty acids, dietary fiber, and essential minerals. Chia seeds enhance viscosity, cohesiveness, and product stability, while almond butter contributes protein, healthy fats, and satiety. Raw cacao powder provides antioxidant polyphenols and natural chocolate flavor, supported by unsweetened coconut flakes and coconut oil for fiber, texture, and emulsification. The addition of dark chocolate pieces and topping enhances sensory appeal without compromising functional benefits.
The preparation process involves blending these whole-food components, molding, and chilling to yield a cohesive, sliceable bar with minimal processing. Physicochemical evaluation demonstrated favourable nutritional values, including 8% moisture, 1% ash, 2.4% fat, 3.65% protein, and 2.36 mg/ml vitamin C, confirming balanced macronutrient distribution and moderate shelf stability without preservatives. The composition retains a dense yet soft texture, balanced sweetness, and structural integrity during storage, making it suitable for vegan, gluten-free, and refined sugar-free applications. Overall, the invention delivers a nutraceutical composition with antioxidant, digestive, and metabolic health benefits, positioned for nutraceutical, functional food, and specialty diet markets.
DETAILED DESCRIPTION OF INVENTION
The present invention lies at the convergence of plant-based nutrition, functional food technology, and clean-label snacking. With rising consumer awareness regarding allergies, chronic metabolic disorders, and the adverse impact of highly processed foods, the demand for nutrient-dense, minimally processed, no-bake functional foods has increased exponentially. Traditional chocolate-based confections are typically rich in refined sugars, dairy derivatives, trans fats, and preservatives, all of which compromise their nutritional value and reduce shelf stability.
The proposed nutraceutical composition provides an alternative by incorporating chocolate, Medjool dates, and a carefully optimized multi-seed blend, delivering enhanced nutritional value and bioactivity. Unlike conventional products, this formulation does not require refined sugar or artificial binders, as Medjool dates act as both the natural sweetener and binder. Dates are rich in soluble fiber, glucose, and fructose, and also provide essential minerals and natural stickiness, enabling structural integrity of the product.
The invention integrates a composite multi-seed blend comprising watermelon, sunflower, pumpkin, chia, flax, soynut, and sesame seeds (~30 g per batch). These seeds supply high-quality plant proteins, omega-3 and omega-6 fatty acids, vitamins (E and B-complex), and minerals (iron, zinc, magnesium, calcium). Chia seeds in particular contribute natural mucilage, enhancing binding, viscosity, cohesiveness, and moisture retention, while also prolonging shelf life.
Additional functional components include:
Almond spread (almond butter): Provides unsaturated fats, plant proteins, and smooth texture.
Raw cacao powder: Supplies polyphenols, flavonoids, and theobromine with neuroprotective and antioxidant benefits while imparting a rich chocolate flavor. Raw cacao is preferred over processed cocoa to retain higher antioxidant activity.
Unsweetened shredded coconut: Adds fiber and textural enhancement.
Coconut oil: Acts as a natural emulsifier, improving lipid uniformity and smoothness after setting.
Dark chocolate cuttings: Provide indulgence, sensory appeal, and additional antioxidant content.
Collectively, the composition constitutes a functional nutraceutical chocolate composition offering a balanced macronutrient profile, bioactive lipid fraction, and natural antioxidants, while remaining vegan, gluten-free, and refined sugar-free. This invention treats whole plant materials using natural emulsion, binding, and gelling functions, altogether, and creates clean-label, science-based responses to classic high sugar sweets. It goes along with the vegan, gluten-free and refined sugar-free snacking trend and can be adjusted to the nutraceutical, functional food and specialty diet sectors

RESULTS:
The prepared Nutraceutical composition was subjected to analysis of their physicochemical properties, with the results presented as follows. The oven drying method was used to estimate moisture content. The equation employed was:

Moisture (%) = ((Initial weight -Final weight)/(Initial weight)) x 100

An 8% moisture content was found to indicate low enough water activity to support moderate shelf stability without the need for preservatives.
The ash content, denoting total mineral residue, was calculated via the formula:
Ash (%) = ((Ash content)/(Total wt of the sample )) x 100
The ash content was at 1%, implying the presence of natural minerals from seeds and dates. The fat content was estimated using Soxhlet extraction with the formula:

Fat (%) = ((Dry wt-empty wt of flask)/(sample wt)) x 100
The measured fat content was 2.4%, indicating a moderate level of almond spread, seeds, and coconut oil in the mix.
Protein estimation was conducted using the Kjeldahl technique. Nitrogen was first identified, and then converted to protein using a conversion factor of 6.25. The formula used was:
Protein (%) = ((B.TV-S.TV) X 6.25 X 0.0014 X 100 X N of NaOH)/(Sample wt. X 0.1)

A protein content of 3.65% suggests a balanced contribution from plant-based protein sources including mixed seeds and almond spread.
The measurement of Vitamin C was carried out via titration, the formula:
Vitamin C concentration in milligrams per milliliter.
Vitamin C = (Observed value x N of Iodine sol. X (Molecular wt of Ascorbic Acid )/2)/1
The vitamin C content was determined to be 2.36 mg/ml, largely due to the presence of dates and residual cocoa antioxidants.
The composition displayed a dense, chewy texture and a mild nutty aroma, topped with a glossy dark chocolate. The combination of dates and seeds yielded a natural sweetness that was balanced by the bitterness of raw cacao. The product maintained its structural stability throughout the slicing and handling process. It can be stored in an airtight container under refrigeration for up to 7 days, or frozen for up to 3 months to extend its shelf life. The mix of seeds in Chocolate composition showed desirable nutritional properties, a pleasing taste, and stable storage, backing up its suitability as a healthy, plant-based functional snack.
