  • Pretreatment method for producing lycopene raw material
    Patent number: 11549128
    Abstract: A pretreatment method for producing a raw material of lycopene, comprising: uniformly mixing tomato peel residue with a fermenting agent, an antioxidant and an enzyme preparation, and subjecting the resultant to light-proof anaerobic fermentation. The present invention employs bacteria-enzyme-combined fermentation technology, which prolongs the storage period of wet tomato peel residue, and also destroys the cell wall of tomato peels, thus facilitating exaction of lycopene and improving the purity of lycopene extracted in the later stage.
    Type: Grant
    Filed: October 25, 2017
    Date of Patent: January 10, 2023
    Assignee: CHENGUANG BIOTECH GROUP CO., LTD.

  • Process for extracting lycopene
    Patent number: 9434886
    Abstract: A process for extracting lycopene, comprising the following steps: pressing and dehydrating tomato pomace which is the by-products of tomato processing production, then drying it to control the water content in the range from 10% to 20%; crushing the dried tomato pomace, and separating tomato skins and tomato seeds by air blast process, granulating the separated tomato skins and extracting them, then purifying by removing impurity from the extracted lycopene with active carbon.
