Study of the Physiochemical and Sensory Properties of Therapeutic Low-Cholesterol Yoghurt Fortified with Zinc Nanoparticles

Abstract

Abstract The objective of this research is to develop a yoghurt enriched with B-cyclodextrin-based nano-coated, uncoated, and low-cholesterol additives. The objective of this study is to assess the impact of fortification on the physicochemical and sensory characteristics of yoghurt. This will be achieved by fortifying raw milk with varying concentrations of nano-zinc., which are 15, 7.5, 3.75 mg / 100 mL The treatments T4, T3, and T2 are denoted as such,, along with the treatment. of yogurt fortified with zinc nanoparticles, which is not coated, represents the treatment T1 and the control treatment, denoted as C, involved the production of yoghurt using milk as the primary ingredient. that was not fortified with zinc nanoparticles. Chemical, physical and rheological tests were conducted in addition to sensory the evaluation will be conducted promptly following the completion of manufacturing and subsequent storage at a controlled temperature range of (1 ± 5) degrees Celsius for a duration of 21 days. The findings indicated that there were no statistically significant disparities in the levels of fat, protein and ash. As for the values of moisture and carbohydrates there were notable disparities observed between the control treatment and the remaining treatments. The total acidity and pH values exhibited minimal variation across all yoghurt treatments. Yogurt treatments fortified with nano-encapsulated zinc were characterized by lower values in ADV and pV. The addition of zinc to yoghurt resulted in enhancements in rheological properties, specifically in terms of spontaneous whey perfusion and viscosity. The experimental group achieved higher scores and demonstrated superior performance in all sensory characteristics when compared to the control treatment, denoted as treatment C.
