Abstract
Present invention teaches the method of using a keratin hydrolysis peptide (“KHP”) solution to enhance sweetness and flavors of tea leaves. By selectively choosing specific weights of feathers and water, and treating the mixture to a high-temperature high-pressure hydrolysis process, the resulting solution is confirmed to contain at least 253 peptides and then applied to the surface of tea leaves during sprouting stage and infused to the soil around the tea trees/plants; the increased content of L-theanine and polyphenol is separately tested and confirmed. Optionally, the KHP solution can be diluted by water, as taught in the specification, before applying to the tea leaves and the soil as taught herein.
