AI Technical Summary

Problems solved by technology

Disadvantages: non-water-soluble nutrients and functional components have not been extracted; the product yield is low, the taste is poor, and the color is poor; the slag is difficult to be comprehensively utilized, the value of raw materials is far from being fully utilized, and the waste of raw materials is large

Disadvantages: low product yield, deep color, many impurities, poor properties, large residual organic solvents; slag is difficult to be reused, and raw materials are wasted; the production process pollutes the environment and has serious safety hazards

Disadvantages: Only fat-soluble products can be obtained, and the water-soluble nutritional functional components cannot be extracted. The slag is only used as ordinary leftovers and has not been well comprehensively utilized, resulting in a large waste of raw materials

[0009] In addition, the taste of the extract obtained by any of the above methods is not good: bitter, numb, dry and astringent
