Production technology of wolfberry (goji) juice concentrate powder and wolfberry juice powder containing wolfberry polysaccharides

1. Technology introduction: The use of solubilization and filter-aid technologies has made the industrial production of wolfberry (goji) extract a reality. The wolfberry extract product has good instant solubility, and the solution is crystal clear and transparent with no precipitation or layering, solving technical problems such as turbidity, precipitation and layering of wolfberry juice and raising the product quality grade. Low-temperature vacuum concentration and two-stage vacuum low-temperature drying technologies give the product excellent color, aroma and taste, with very little loss of nutrients during processing.

Enzyme hydrolysis technology is adopted to improve extraction efficiency and moderately adjust the viscosity of the slurry, improving processing performance while ensuring product quality.

Two-stage countercurrent hot water extraction technology is adopted to maximize the extraction rate and reduce costs.

This technological achievement has passed the scientific and technological achievement appraisal organized by the Science and Technology Department of Ningxia, and the technology has reached the domestic advanced level. The achievement belongs to Ningxia Zao'an Soy Milk Co., Ltd., and national patents have been applied for, with patent application numbers: 02128459.8 and 01130410.3. This technology is an agricultural scientific and technological achievement transformation project.

2. Economic benefits: In a normal year, the total annual tax paid reaches 10.945 million yuan (including income tax), the net profit can reach 21.6226 million yuan, and the input-output ratio of the project is as high as 1:3.8, making it a high-tech project with low input and high output.

3. Applicable regions: Applicable to all regions.

4. Promotion method: Joint venture and cooperation.
