Problems solved by technology

The defect of this kind of production method is: because the spray drying method is to use the emulsion to be atomized into fine particles during the heating process and then heated and sprayed dry, so the material will lose oil and fat-soluble nutrients during the process of contacting air and heating. Inevitably oxidized, reducing the effective ingredients of nutrients and producing harmful peroxides and trans fatty acids

Abstract

The invention relates to a nutrient freeze-drying production method, which comprises: making the nutrient into emulsion in a emulsifying machine; putting the emulsion into a vacuum freeze-drying chamber for vacuumizing and quick-freezing; sublimating by heating to obtain a dry anhydrous solid matter; and grinding the freeze-dried solid matter into powder in a grinding machine. By making the nutrient into powder by vacuum freeze-drying technology, the invention avoids the generation of peroxides and trans-fatty acid which is harmful to human body cuased by the oxidation of grease and fat-soluble nutrients, consequently, protects the active components of nutritious oil and fat-soluble nutrients. The powder made by the method achieves good stability and a long shelf life.

Description

technical field [0001] The invention relates to a production method of nutrient oil or / and fat-soluble nutrient powder, in particular to a production method of freeze-drying nutrient substance. Background technique [0002] The traditional technique for preparing nutrient oil or / and fat-soluble nutrient powder is the spray drying method. Due to different spraying methods, it is divided into pressure spray drying, airflow spray drying and centrifugal spray drying. The commonality of these drying methods is to use the spray principle to spray and dehydrate the emulsion of nutrient oil and fat-soluble nutrients. For example, the process of pressure spray drying is as follows: emulsion → (high pressure pump atomization) → {(in spray drying tower top mixing)→mixture→air→(filtering, heating)→powder or granular solid finished product→(fog drops are heated to evaporate water)}→(exhaust fan, tap water condenses)→waste liquid. The defect of this kind of production method is: because...
