description | The aim of this study was to determine some of the nutritional properties from the decaffeinated tea waste. The tea extract waste had the potential to be used as
animal feed. Minerals content analysed in this study were sodium (Na), copper (Cu), calcium (Ca), Iron (Fe), Zinc (Zn), magnesium (Mg), potassium (K) and phosphorus.
The nutritional properties that had been determined were lipid, protein and minerals. For the lipid, it was determined by undergo the process in soxhlet extraction system. There was only 0.25 w/w % of lipid found in the decaffeinated tea extract waste. The quality of decaffeinated tea waste can be improved by mixing with other plant like soy bean to become animal feed. Protein was determined according to the kjedahl digestion method. The optimal percentage of protein that need in poultry feed is
10.0 % but there was only 5.85 % of protein was present in tea extract waste. Three minerals found in decaffeinated tea extract waste were copper (Cu), iron (Fe), and sodium (Na) which were 0.1644 mg/g, 0.0860 mg/g and 0.0467 mg/g respectively. Besides that, amount of total other minerals that presented were phosphorus, 0.0031 mg/g, calcium, 0.0124 mg/g, magnesium, 0.0168 mg/g, zinc, 0.0318 mg/g and potassium, 0.0350 mg/g. These minerals play important roles in poultry growth. |
