Opis:
In this study, the proximate, mineral, anti-nutrient content and sensory evaluation of the tea brands sold in Nigeria were evaluated. Fours brands including Lipton tea (LPT), Anti Malaria Tea (AMT), Green Tea (GRT) and Eternal slimming tea (SLM) and lemon grass tea (LEM) as control were studied. The official methods of Analysis of Association of Analytical Chemists were adopted for the analysis. Results for proximate showed that GRT showed significant difference (P>0.05) Moisture content (5.99 %) while SLM had significant low value p≤0.05 (4.85 %) compared to LEM (control) (5.12). The Protein content of the tea samples was discovered in traces having SLM as the highest (0.46 %). The crude fat as ether extract of the samples ranged between LPT (3.18) as the highest (3.18 %). SLM appeared to have high (6.08) value in Ash and GRT lowest value. LEM (control) had a high (88.58 %) value in Carbohydrate compared to the other tea brands with LPT as the lowest (86.03 %) value. The results of the mineral analysis showed that LEM has the highest (28.31 mg/kg, 85.96 mg/kg and 18.31 mg/kg) for calcium and potassium content respectively SLM had the highest (7.35 mg/kg) value for Magnesium. Antinutrient results showed that all teas brands had traces of alkaloid at various values ranging from GRT (0.15 mg/kg) to SLM (0.01 mg/kg). Phytate and oxalate was not detected at all in GRT and was discovered in traces the other tea brands. The average taste scores of tea samples ranged from 6.60-5.30 with highest (6.75) taste scores assigned to sample LPT while lowest (4.95) taste scores were observed in sample AMT. The four tea brands evaluated in this study are nutritionally valuable, including the natural extract of lemon grass which contains zinc, which helps boost the immune system and acts as an antioxidant that protects the body. The content of this tea brands and lemon grass are also safe.
