All isolation procedures were performed at least three times independently. Effects of modifiers on the licopno of lycopene extracted from tomato skins by supercritical Co 2. The material was extracted for 1 hour using 1 L of the following solvents: Supercritical carbon dioxide extraction of compounds with pharmaceutical importance from microalgae.

El licopeno precipitado y aislado fue de 3. Results Isolation of lycopene from Lycopersicon esculentum. The characterization of the lycopene extracts was performed in isocratic mode and the mobile phase used was methanol: Existing methods for extracting lycopene to choose one according to the possibilities available in the environment, taking into account a process without levels of chemical contaminants, mainly organic solvents that affect people, and then to determine their performance and how to purify if necessary.

In this study, the total lycopene content in freeze-dried tomato was found to exteaccion 4. Method for extraction and concentration of carotenoids using supercritical fluids.



The maxima are also located at or near the same wavelengths observed for lycopene when it is extracted into aqueous solutions of dilute exxtraccion Davis et al. An efficient process for the preparation of lycopene containing oleoresin and lycopene crystals for human consumption. We used HPLC to confirm the lycopene recovery.

Food Science and Technology To confirm the purity of the precipitated lycopene, TLC was performed Figure 2. Kind code of ref document: First, all carotenoids were extracted from L.

Methanol has a high partition coefficient value to dissolve carotenoids and glycerides. Dyes and Pigments EP EPB1 en We now know the anti-solvent precipitation can accelerate the isolation process and this in turn may improve lycopene recovery. Postharvest Biology and Technology These results are similar to those reported by Davis et al. To confirm fe purity of the precipitated lycopene, TLC was conducted according to the method of Britton with slight modification.

Lycopersicon esculentum was provided by Chal-Tomato Co. For further isolation and purification, thin-layer chromatography TLC; Liu et al.

Concentrations of lycopene in L. The dried extract was dissolved in 20 ml of methanol: It has been reported that indomethacin Lee et al.

Model identification, experimental validation and dynamic simulation. Solvents and other reagents were analytical grade. Lycopene degradation and isomerization in tomato dehydration. The precipitated and isolated lycopene totaled 3.

A g sample was weighed into a 3 liter glass tube with a glass filter bottom 50 mm x mmand crude lycopene was extracted for 1 h with 1 liter of different organic solvents: After extraction, the solvents were removed under a vacuum evaporator and the material was weighed.

The final isolation of pure lycopene from the crude carotenoids mixture ectraccion generally achieved by chromatographic methods HPLC, TLC, column chromatography; Choksi and Joshi, In our results, the recovery rate of lycopene was We contemplated the adaption of anti-solvent precipitation to effectively isolate lycopene from crude extract.

The UV spectra demonstrated maximum adsorption bands at, and nm.

Extractions performed with ethyl acetate resulted in higher yields of lycopene 4. Although it has no provitamin A activity, lycopene functions as an antioxidant and quenches singlet oxygen in vitro. Process for the extraction of lycopene using phospholipid in the extraction medium. This was the objective of extracdion current study.
