Chinese peony anthocyanin tea and preparation method thereof

Abstract

The invention relates to Chinese peony anthocyanin tea and a preparation method thereof, and belongs to the field of tea product processing. The preparation method of the Chinese peony anthocyanin teacomprises the following steps of washing petals of Chinese peony, and carrying out microwave fixation so as to obtain a pretreated material; adding distilled water into the pretreated material, and carrying out beating so as to obtain pulp; adding cellulase and pectinase into the pulp, and carrying out water bath treatment so as to obtain a primary material; inoculating the primary material witha compound fermentative bacterium agent, and carrying out fermentation so as to obtain fermented liquid; performing homogenization treatment on the fermented liquid so as to obtain homogenized liquid;adding a mixture of modified starch and sodium caseinate into distilled water, and carrying out stirring until the mixture is dissolved so as to obtain a mixed solution; uniformly mixing the homogenized liquid with the mixed solution, and performing decompressed concentration so as obtain an extract; and then, drying the extract, carrying out granulation, carrying out coating with honey, and carrying out vacuum freeze-drying so as to obtain the Chinese peony anthocyanin tea. By adopting the preparation method, anthocyanin ingredients in Chinese peony flowers are made full use of, and stability and retention rate of the anthocyanin ingredients are increased; moreover, the other nutrients are balanced by performing fermentation, and thus, the prepared Chinese peony anthocyanin tea is comprehensive in nutrients and relatively good in taste.

Description

technical field

[0001] The invention belongs to the field of tea product processing, and in particular relates to a peony anthocyanin tea and a preparation method thereof. Background technique

[0002] Anthocyanin is a water-soluble pigment, which belongs to flavonoids in phenolic compounds. It is widely found in the tissues of plant petals and fruits, as well as the surface cells and lower epidermis of stems and leaves. It is the main pigment that constitutes the color of petals and fruits. one. Its color changes with pH, ​​thus endowing many plants in nature with bright and vivid colors. In recent years, attention has focused more and more on the possible health benefits of anthocyanins as polyphenols, which are fundamentally powerful antioxidants that protect the easily oxidized They work together with other components in plants and have high bioavailability. Anthocyanins are significantly higher than VC in terms of the ability to resist free radicals and protect lipid ...
