Abstract
The invention discloses a preparation method of a Fu tea water extract with high light transmittance. The preparation method comprises the following steps: preparing Fu tea, adding water, carrying out extraction, performing solid-liquid separation, storing the extract at a low temperature, then carrying out centrifugation to obtain a liquid Fu tea extract; condensing the liquid extract to obtain a concentrate; adding edible alcohol into the concentrate, storing the solution at a low temperature, then subjecting the solution to centrifugation to obtain an alcohol precipitation concentrate, and subjecting the alcohol precipitation concentrate to vacuum concentration to obtain the Fu tea extract. The Fu tea extract prepared through an alcohol precipitation method does not contain any alcohol, and can be directly used as a raw material or an auxiliary material of tea beverages. The light transmittance of the tea soup can reach the requirements of beverage enterprises. The Fu tea extract can be stored for a long time without any high temperature sterilization treatment. The Fu tea extract is safe, convenient and efficient, and can be widely used in the tea beverage industry.
Description
Technical field
The present invention relates to the preparation method of high-transmittance water extraction Fu tea extract is and in particular to one kind is prepared with Fu tea for raw material
The method of high-transmittance water extraction Fu tea extract.
Background technology
Fu tea is one kind of black tea, has fat-reducing aid digestion, anticancer, hypoglycemic, the coordinating intestines and stomach anti diar rhea of lipid-loweringing etc. multiple
Health care, therefore Fu tea beverage become the teabag drink of in recent years each big drink enterprise focus development.Traditional water extraction tea concentrate/leaching
Flooding tealeaves typically used by cream, through filtering or being centrifuged, concentrate and make, does not have tea grounds and keeps the paste of the peculiar taste of tealeaves to produce
Product, can use directly as tea beverage supplementary material.Existed serious using the Fu tea concentrate/medicinal extract of traditional extraction process by water preparation
Cream down phenomenon, is unable to reach the light transmittance standard of the net millet paste of tea beverage after reduction, need to through multiple times of filtration clarifying treatment
The net millet paste requirement of production can be reached, this will certainly improve drink enterprise production cost, reduces production efficiency.
Application for a patent for invention in Publication No. CN102696811A《A kind of preparation method of instant dark tea》, disclose mesh
Front domestic processed solving the example of the turbid problem of black tea cream down with compound enzyme technology, but because enzyme preparation is relatively costly,
And can not reuse, therefore limit its industrial applications.
