Comparative study of the proximate analysis and phytochemical screening of yellow and black tigernut Department:Pharmaceutical Technology By: Muhammnnad1 Project ID: 9040 Rating: (5.0) votes: 1 Price:₦5000 Get the Complete MaterialAbstractA comprehensive comparative analysis was conducted to evaluate the proximate composition and phytochemical profile of yellow and black varieties of tiger nut (Cyperus esculentus). The study revealed significant varietal differences in both nutritional and bioactive components. The black tiger nut demonstrated superior protein (25.14%) and fat (32.56%) content, while the yellow variety showed higher carbohydrate (19.24%) and crude fiber (19.86%) levels. Phytochemical screening identified distinct bioactive patterns: the black variety exhibited strong positive results for flavonoids (+++), tannins, and phenols, whereas the yellow variety showed only moderate flavonoid presence and absence of tannins and phenols. Both varieties tested positive for alkaloids and saponins. The results demonstrate fundamental metabolic specialization between varieties: the black tiger nut represents a defense-oriented chemotype with integrated high-nutrient and high-antioxidant characteristics, while the yellow variety exemplifies an energy-specialized strategy prioritizing carbohydrate storage and mineral content. Strong correlations were observed between proximate and phytochemical parameters, particularly between high fat content and flavonoid concentration, and between high protein and tannin presence in the black variety. These findings provide a scientific basis for cultivar-specific applications in functional food development, nutritional supplementation, and agricultural breeding programs. The study establishes that yellow and black tiger nuts constitute distinct nutritional entities requiring differentiated utilization strategies in food systems and health applications. ...Preview Download Preview +Other Pharmaceutical Technology project topics and materials you might be interested in»Comparative analysis of the acidity of different brands of folic acid sold in Owerri»Knowledge, attitude and practice of prescription of drugs among school of community health science College of Health Sciences and Technology, Tsafe, Zamfara state»Spectroscopic analysis of the first eluate of Piper Guineense extract»Analysis of the impact of electronic prescribing on medication safety and efficiency»Phytochemical screening, proximate and elemental analysis of two varieties of bitter kola (Garcinia kola) seed sold in Mariri market, Kano state»Identification of phytochemicals responsible for anti-ulcer activity of acioa barteri using high performance liquid chromatography-diode array detector (HPLC-DAD)»Antimicrobial activity of Acioa Barteri and its synergestic effect with Darlium Guineense»Formulation of ointment using Mitracarpus Scaber extract and its antifungal activity against clinical isolate»Comparative analysis of different absorbance of paracetamol using spectrophotometer»Phytochemical analysis and antifungal activity of Syzagium Aromaticum against some fungal isolates»Formulation and evaluation of toilet soap using suitable raw materials»Comparative analysis of phytochemical constituent and the proximate composition of green and red apple»Comparative study of the proximate analysis and phytochemical screening of yellow and black tigernut
