Formulation and Evaluation of Anti-Diabetic Chocolate from Fruit Extracts

Abstract

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia and associated complications, necessitating the development of safer and patient-friendly therapeutic approaches. The present study focuses on the formulation and evaluation of a nutraceutical product in the form of fruit extract-enriched dark chocolate for diabetes management. Cocoa flavonoids present in dark chocolate, along with bioactive compounds from selected fruits such as Mangifera indica (mango) and Ananas comosus (pineapple), offer significant antidiabetic potential through antioxidant activity, enzyme inhibition, and improvement of insulin sensitivity.The formulation was prepared by incorporating fruit extracts into a dark chocolate base along with cocoa butter, honey as a natural sweetener, and rosemary as a natural antioxidant and preservative. Different formulations were developed and evaluated for organoleptic properties, physicochemical parameters, and chemical characteristics. The prepared chocolates exhibited desirable attributes including uniform dark brown color, acceptable taste, and good consistency. The pH of the formulations ranged from 5.2 to 5.32, indicating suitability for consumption.Chemical evaluation confirmed the presence of carbohydrates and proteins, while weight variation studies indicated uniformity in formulation. Stability assessment showed no evidence of fat bloom, suggesting good product stability. The combined effects of cocoa flavonoids and fruit-derived phytochemicals demonstrated a potential synergistic role in improving glycemic control.In conclusion, the developed fruit extract-enriched dark chocolate represents a promising nutraceutical formulation with potential antidiabetic benefits, improved palatability, and enhanced patient compliance. However, further in-vitro, in-vivo, and clinical studies are required to validate its therapeutic efficacy and safety.
