Abstract

The invention discloses a preparation method of high-concentration lycopene oil resin. The preparation method is characterized by comprising steps as follows: tomato juice prepared from fresh tomatoes is subjected to centrifugal separation, supernatant is removed, precipitate is reserved, edible vegetable oil is added, and the mixture is uniformly mixed; constant-temperature extraction and centrifugal separation are performed, precipitate is removed, supernatant is reserved, edible ethanol and lecithin are added after obtained tomato plant oil containing lycopene is heated, and the mixture is uniformly mixed; the mixture is cooled and slowly stirred, lycopene is crystallized, and coolingcentrifugation is performed; lycopene crystals on the lower layer are separated, edible alcohol is distilled to the liquid state, the precipitate is washed and distilled until no liquid flows out, and the lycopene oil resin is obtained and is stored away from light. The extraction process is simple, large-scale production can be performed, the applicability is wide, the production cost is low, the extraction process consumes short time, the production efficiency is improved, and the lycopene oil resin is non-toxic, doesn't have residues and is beneficial to body health.

Description

Technical field: [0001] The invention relates to a preparation method of high-concentration lycopene oleoresin, and belongs to the technical field of biological food. Background technique: [0002] At present, the preparation method of existing lycopene oleoresin has the following shortcomings: [0003] 1. The use of chemical additives, such as methanol, acetone and other organic chemical reagents, will cause serious residues of toxic substances, which is not conducive to human health. [0004] 2. The applicability is narrow, and it is only applicable to a certain fruit. [0005] 3. The extraction steps are complex, the procedures are many and time-consuming, and some require a pressurizing device, which is not conducive to factory-scale production. Invention content: [0006] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a simple extraction process, large-scale production, wide applicability, low product...
