Abstract

The present invention provides a preparation method of olea europaea leaf black tea. Olea europaea leaves are selected, the selected olea europaea leaves are moistened with water, aspergillus niger is inoculated for a first fermentation, when the olea europaea leaves turn soft in texture, kneading is conducted, then monascus purpureus is inoculated to conduct a second fermentation, and after the fermentation, the fermented olea europaea leaves are dried to prepare the olea europaea leaf black tea. The prepared olea europaea leaf black tea by the method is red brown in color, mellow in ester fragrance, and mellow in tea flavor, and contains the substance of monacolin K having blood lipid reducing effects.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of olive leaf black tea. Background technique [0002] Olive is an evergreen tree of Oleaceae Oleaceae. It is a world-renowned woody oil and fruit tree species. The cultivated species have high edible value and are rich in high-quality edible vegetable oil-olive oil. It is a famous subtropical fruit tree and an important economic tree. It is mainly distributed in Mediterranean countries, with Greece, Italy, Tunisia and Spain as the concentrated production areas. For a long time, people have limited their use of olives to their fruits, ignoring the huge value of olive leaves. Olive leaves contain choline, tea polyphenols, rutin, stevioside, various proteins, various vitamins (A, C, D, E, K, B1, B12, H, β-carotene, etc.), Various trace elements (sodium, iron, zinc, copper, calcium, phosphorus, manganese, chromium, molybdenum, iodine, selen...
