The invention belongs to the technical field of
food processing, and particularly relates to a preparation method of
common turnip powder without hot taste. The preparation method comprises the following steps of selecting fresh
common turnip rhizomes, performing washing, performing trimming,
cutting the treated
common turnip rhizomes into slices, putting the common turnip
rhizome slices into
alkaline water, performing heating to a boiling state, performing draining, performing freezing at minus 20 DEG C, performing complete natural unfreezing on the frozen common turnip slices at
room temperature, squeezing the unfrozen common turnip slices, collecting common turnip juice obtained through squeezing,
drying the squeezed common turnip slices, and performing crushing and screening so as to obtain the common turnip
powder. According to the preparation method disclosed by the invention, the hot taste of the common turnips is effectively removed with the
alkaline water, favorable mouth feelis given to the common turnip
powder, through a freezing technology, the common turnips are processed into powder, the common turnip powder can be widely used for food and
beverage industry, raw materials of health-care foods and ingredients in production of medicines, the application prospect is great, the operation is simple and convenient, the preparation method belongs to a new technology easy in large-scale production, the
processing technology does not blowdown
pollution, the
blanching working procedure is not used, and depletion
energy resources is saved.
