Problems solved by technology

[0002] It is an existing technology to prepare freeze-dried wolfberry powder after peeling and seeding fresh wolfberry. The wolfberry powder produced by this method has pesticide residues, is easy to get damp and agglomerated, and has coarse particles, generally less than 80 mesh. It contains a lot of fiber, vitamins, oils and other nutrients that are beneficial to the human body. It is a pity to discard it. The size of the particle size directly affects the deep processing and use of wolfberry powder. Because the sugar content in wolfberry is extremely high, it is easy to stick when crushed. , it is difficult to crush it above 100 mesh

Embodiment 1

[0013] Embodiment 1: with the fresh fruit of Lycium barbarum as raw material, the first step of its technological process is to reduce pesticide treatment, adopts the method for adding organic acid to potassium permanganate, prepares 0.1 (W) of potassium permanganate containing, organic acid thousandth 0.5 (W) aqueous solution, soak wolfberry in it for 10 minutes, and keep stirring, take out and drain, rinse with running water for 3 to 5 minutes, then put in the solution containing ClO 2 After soaking in 0.2% aqueous solution for 10 minutes, take it out and drain it, put it on a plate and move it into the freezer, quickly lower the temperature to below -40°C, put the frozen wolfberry fresh fruit into the sublimation dryer, and control the sublimation temperature at -10~ -20°C, vacuum degree 80-100Pa, it takes about 10 hours, take it out and put it into a freezer grinder, control the temperature of the material not to exceed 0°C, grind it to a fineness > 100 mesh, and then carry...

Embodiment 2

[0014] Example 2: Using dried wolfberry as raw material, the dried wolfberry was first treated to reduce pesticides according to the method in Example 1, and then the dried wolfberry was rehydrated, and the subsequent treatment method was the same as in Example 1.

The production process of whole lycium berry powder includes the following steps of reducing pesticide residue, rinsing, freezing, lyophilizing, low-temp. pulverizing and composite packaging, and the fineness of the whole lycium berry powder produced by said invented process is up to above 100 meshes, and said product has no lump, and contains no pesticide residue, and can meet the American FDA quality standards.

Description

technical field [0001] The invention relates to a processing method of health food, in particular to a freeze-sublimation drying process. Background technique [0002] It is an existing technology to prepare freeze-dried wolfberry powder after peeling and seeding fresh wolfberry. The wolfberry powder produced by this method has pesticide residues, is easy to get damp and agglomerated, and has coarse particles, generally less than 80 mesh. It contains a lot of fiber, vitamins, oils and other nutrients that are beneficial to the human body. It is a pity to discard it. The size of the particle size directly affects the deep processing and use of wolfberry powder. Because the sugar content in wolfberry is extremely high, it is easy to stick when crushed. , it is difficult to crush it above 100 mesh. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process of wolfberry whole powder with no pesticide residue, no moisture return...
