oluble portion. By treating tea extracts with iron lactate solution, black dye can be produced. Tea polyphenols impart stability to these colors, making them heat-stable and resistant to enzymic action and microbial growth(1, . 7.3 Vitamins and Minerals Dried tea leaves and tea waste are comparable to dried alfalfa leaves in their vitamin and mineral content, and vitamin an can be produced from vegetative waste of tea bushes. 7.4 Extenders in Polymers In the production of phenolformaldehyde resin, partial replacement of phenol with tea waste polyphenols increases the owability of the resultant resin, without adversely affect-ing the polymer characteristics, and reduces the cost. Adhesives for wood that have high water content are prepared by using tea powder as ller, producing high ow values. The replacement of the existing resins in plywood adhesive with tannin polymers from teawaste appears to be possibility. 7.5 Animal Feed and Composting Spent tea waste, which is rich in crude protein and amino acids, can be good source for animal feed formulations. 7.6 Tobacco Substitutes and Foaming Agents Tea waste tannins are used in lters for tobacco smoke and as tobacco substitute sheets by grinding to paste, mixing with plasticizing substances, and rolling into sheet. foaming agent produced from tea extract can be used as substitute for egg white. 7.7 Triacontanol, New Plant Growth Regulator from Tea Instant tea waste, obtained from green tea leaves, contains maximal amount of triaconta- nol. Triacontanol in quantities as small as 5 mg/Ha enhances the yield of some crops, Tea 7 such as tomato, cucumber, lettuce, maize, corn, and rice. Trials on tea plants showed an increase in harvestable yield of 2%3% with reduction in the dormant shoots. Tests ofthese materials on other crops also showed good and encouraging results. 7.8 Tea Seed Oil Tea seed contains 2%4% oil, which resembles groundnut and olive oils. It is rich in unsaturated fatty acids, especially lino
