Processing method for improving selenium enrichment of tea flowers

Abstract

The invention discloses a processing method for improving selenium enrichment of tea flowers, belongs to the field of tea leaf making, and aims to obtain selenium-enriched tea flowers with excellent color and flavor by applying an exogenous selenium fertilizer to improve the selenium enrichment of fresh tea flowers and adopting a freeze drying technology. Liquid nitrogen is used for freezing, so that the tea flowers are quickly cooled, biological structures and gaps in the tea flowers are kept, ice crystals at the positions of the tea trees support the tea flowers, and the gaps are reserved when the ice crystals sublimate, so that the biological and chemical structures of the tea trees and the integrity of the activity of the tea trees are reserved. The original color, fragrance, taste and other chemical components of the tea leaves can be preserved to the maximum extent, so that the natural color, fragrance and taste of the tea leaves can well pass through pores when the tea leaves are brewed, and the tea flowers contain 90% or above of tea polyphenol, amino acids, tea polysaccharide, proteins, saponin and other substances, which are beneficial to the human body. The tea flowers have the effects of detoxifying, lowering lipid, lowering blood sugar, resisting aging, resisting cancer, inhibiting cancer, nourishing, strengthening body, nourishing skin, beautifying features and the like.

Description

technical field [0001] The invention relates to the field of tea production, in particular to a processing method for improving the selenium-enrichment of tea tree flowers. Background technique [0002] Selenium is one of the 15 kinds of trace elements necessary for the human body, and also one of the very important non-metallic trace elements related to various diseases of the human body. It can regulate the body's immunity, anti-aging, and remove harmful free radicals in the body Features. Therefore, the development and utilization of selenium resources to produce natural selenium-enriched health food and selenium-enriched agricultural products has gradually become a new hot spot in my country's health food industry. [0003] Tea tree flower is the reproductive organ of tea tree. Due to its long growth period, tea tree flower has accumulated a large amount of organic substances in its body, especially the content of tea polyphenols, amino acids, proteins, tea polysacchari...
