Method for preparing deer bone frozen powder by ultrasonic degradation

Abstract

The invention relates to a health care food and a preparation method thereof, in particular to a method for preparing deer bone frozen powder by ultrasonic degradation. The method comprises the following steps of: cleaning a deer bone without anadesmas, crushing, and adding acetone to remove fat in the deer bone and prepare defatted deer bone powder; grinding the defatted deer powder with a colloid grinder to obtain deer bone slurry of 200-230 meshes; mixing the deer bone slurry and active water to form a suspension; crushing the sufficiently dispersed and emulsified deer bone suspension by an ultrasonic continuous flow cell crusher under stirring to fracture cell membranes and fully release the active substances in the cells; directly sublimating the target drying substance by utilizing a frozen drying and condensing technology to remove moisture, wherein drying by heating is avoided to prevent the inactivation of the active substances of the deer bone in the preparation process. The deer bone frozen powder has complete nutrition and high activity, and the preparation method needs short extraction time, reduces the loss of active substances and improves the utilization rate of the deer bone. The invention has the advantages of simple process, low production cost and shortened production period.

Description

technical field [0001] The invention relates to a health food and a preparation method thereof, in particular to a method for preparing deer bone freeze-dried powder by ultrasonic cracking. Background technique [0002] At present, the technology of deep processing of deer bone in our country is relatively backward, and the traditional method of high-temperature cooking and heating, roasting and crushing is adopted now. This high-temperature heating processing method will cause a large amount of damage and loss of active ingredients in deer bone. The value is also greatly reduced, especially the active substances in the deer bone are almost completely inactivated. Contents of the invention [0003] The object of the present invention is to address the above-mentioned shortcomings and provide a method for preparing deer bone freeze-dried powder with good health care effect, high utilization rate of the extract, short extraction time, and ultrasonic cracking of the extract r...
