  • METHOD FOR OBTAINING PRODUCTS FOR THE FOOD INDUSTRY AND/OR FEED INDUSTRY FROM INSECTS, AND SOLID PHASE OBTAINED FROM INSECTS
    Publication number: 20210315234
    Abstract: A method for obtaining products for the food industry and/or feed industry from insects at the larval stage involves: a) comminuting the insects to form an insect pulp; b) shifting the pH-value of the insect pulp to an acid range by adding an acid and malaxing the insect pulp for a period of at least 45 minutes; and c) fractioning the insect pulp using centrifugal treatment into at least two fractions i) a solid fraction, ii) a fatty phase; and a fat-reduced solid phase.

  • Method for the fractionation of oil and polar lipid-containing native raw materials
    Patent number: 7550616
    Abstract: The present invention relates to a process for the production of polar lipid-rich materials and preferably phospholipids. Preferably the polar lipid-rich materials are separated and recovered from de-oiled native raw materials by extraction with water and alcohol and use of density separation to separate the resulting mixture. The invention also includes an improved process for de-oiling the native raw material before extraction and recovery of the polar lipids.
